3. Filter by borough, street address, or tax lot to narrow parcel data.
4. Download CSV export or view API access for bulk analysis of complaints and open permits.
5. Cross-reference with BIS system (Building Information System) for certificate of occupancy and active violations.

For example, BIN 3729561 returns 45 DOB records showing elevator inspections, ECB violations, and construction type. This reveals year built, number of floors, and litigation history. Pair it with HPD data for rodent infestation or lead paint issues, and PLUTO for assessed value and land use.

Experts recommend verifying data freshness via last modified dates in the data dictionary. Combine with ACRIS for sales history and DOB NOW for permit status. This process ensures a full building profile from public records.

Key Portals (Buildings, DOB, HPD)

Use BIS (a810-bisweb.nyc.gov) for DOB records, HPDOnline (hpdonline.nyc.gov) for housing complaints, and data.cityofnewyork.us for integrated API access. These portals form the core of a thorough Building Check in NYC. They provide essential property data like violations, permits, and ownership details.

The Department of Buildings (DOB) BIS system offers detailed real estate records on job applications, certificates of occupancy, and open permits. Search by address, borough, block, lot (BBL), or BIN to uncover construction history and compliance status. HPD focuses on building conditions, including class B and class C violations for issues like heat complaints or rodent infestation.

NYC Open Data integrates these sources into 50+ datasets for bulk analysis. Experts recommend starting with BIS for DOB data, then cross-referencing HPD for complaints and violations. This approach reveals full building profile insights, from year built to active ECB violations.

Portal	Records	Search Types	Update Frequency	Best For
BIS	DOB jobs and permits	Address, BBL, BIN, owner name	Daily updates	Construction docs, violations, occupancy
HPDOnline	Housing complaints and violations	Address, BBL, owner address	Real-time	Class B/C violations, emergency repairs, litigation
NYC Open Data	50+ datasets (PLUTO, DOB, HPD)	API, bulk download, GIS layers	Weekly to monthly	Property valuation, zoning, spatial data

Login requirements vary: BIS and HPDOnline need free accounts for full access, while NYC Open Data is public. Use the data dictionary in each portal to understand fields like square footage or zoning district. Combine them for checks on stop work orders, vacate orders, and 311 service requests.

Building Identification Number (BIN)

The 7-digit BIN, such as 3729561 at 123 Main St, uniquely identifies each structure in DOB/BIS systems across NYC buildings. This building identification number serves as a key link in NYC Open Data for accessing property data. It helps users cross-reference records efficiently during a building check.

The BIN structure starts with the first digit indicating the borough: 1 for Manhattan, 2 for Bronx, 3 for Brooklyn, 4 for Queens, and 5 for Staten Island. Remaining digits detail the specific building within Building Information System records. This format ensures precise tracking in DOB data and related datasets.

To lookup a BIN, use the BIS search tool or explore the PLUTO dataset on the data portal. Cross-reference with HPD and DOF records by matching the BIN to addresses, BBL, or owner name. For example, BIN 3341477 links to 28 DOB jobs and 15 HPD violations, revealing permits, complaints, and violations.

During a building check, verify BIN against multiple sources like DOB job data, HPD violations, and PLUTO parcel data. This reveals building class, square footage, year built, and active issues such as open permits or ECB violations. Experts recommend noting the BIN early to streamline access to real estate records and compliance history.

Borough-Block-Lot (BBL)

The 10-digit BBL (ex: 1001410023 = Bronx Block 141 Lot 23) identifies tax parcels in PLUTO/ACRIS datasets for property valuation and ownership. This unique code breaks down into Borough (1 digit) + Block (5 digits) + Lot (4 digits). It serves as a key identifier across NYC Open Data for linking building information.

In the PLUTO dataset, enter a BBL to access parcel data like assessed value, zoning district, and square footage. For example, BBL 2071730011 in Manhattan reveals building class, year built, and number of floors. This helps in evaluating property valuation during a building check.

ACRIS deeds provide deeper insights using the same BBL for sales history and ownership details. Searching 2071730011 shows a $15M sale and LLC ownership, plus mortgage records. Combine PLUTO and ACRIS for a full picture of real estate records.

To lookup a BBL, start with an address in the NYC Open Data portal, then cross-reference in PLUTO for land use and ACRIS for deed records. Experts recommend verifying BBL across datasets for accuracy in property searches. This approach uncovers owner name, tax class, and exemption codes efficiently.

Address and Street Details

Standardized addresses include house number, street name, borough, and BIN/BBL cross-references for geocoding via NYC GeoClient API.

These fields help users pinpoint exact locations in NYC Open Data building checks. For example, a record might show 123 Main St, Manhattan with linked identifiers for precise mapping.

The dataset provides six key address fields for comprehensive property data. These include House#, Street Name, Borough, BIN (Building Identification Number), BBL (Block and Lot), and Latitude/Longitude.

• House# captures the numeric portion, like 456.
• Street Name follows normalization rules, standardizing St to Street.
• Borough specifies Manhattan, Brooklyn, or others.
• BIN links to Department of Buildings records.
• BBL identifies the tax lot uniquely.
• Latitude/Longitude offers geographic coordinates for GIS analysis.

NYC GeoClient API endpoint standardizes these inputs for accurate results. Normalization rules ensure consistency, converting variations like Ave to Avenue or handling abbreviations. This supports reliable building information retrieval in BIS system queries.

Users checking buildings benefit from these details for cross-referencing DOB data, HPD records, or PLUTO dataset parcels. Always verify against the data dictionary for field names and update frequency.

Owner and Contact Information

DOF tax rolls on NYC Open Data reveal owner names and addresses for most properties. These records come from the Annual Tax Roll dataset. They help identify who controls a building through public real estate records.

Common examples include 123 MAIN LLC c/o AKAM Associates, 100 Park Ave. This format shows the owner name and mailing address. ACRIS provides additional mailing address details from deed and mortgage records.

Beneficial ownership often remains hidden behind LLCs and trusts. NYC Open Data exposes the registered owner but not ultimate beneficiaries. Cross-reference with ACRIS for ownership history and sales data to build a fuller picture.

When checking a building, search by BBL or address in the DOF Property Valuation dataset. Combine with ACRIS for deed records and recent transfers. This approach uncovers key contacts for inquiries or due diligence.

Building Classification (Class A/B)

DOF Class A buildings feature elevators and often have 6 or more stories, while Class B buildings are typically walk-ups. This classification determines maintenance standards and HPD oversight in NYC Open Data. Checking building class helps assess property risks during a building check.

Class A properties face stricter rules for elevator inspections and fire safety systems. Class B buildings, common in older neighborhoods, often deal with more heat complaints and lead paint issues. Use NYC Open Data to filter by class for targeted property data searches.

Legal differences include higher HPD scrutiny for Class A on boiler inspections and facade safety under Local Law 11. Class B may have more leniency but higher rates of class B violations like rodent infestation. Review DOB data and HPD datasets for full building conditions.

Class Code	Description	Typical Unit Count	Common Violations
A1	Two-Family Homes	2 units	Heat complaints, minor plumbing
A5	Eight-Family with Elevator	8 units	Elevator issues, ECB violations
A9	Ten-Family with Elevator	10 units	Fire safety systems, hot water
B1	Two-Family Walk-Up	2 units	Lead paint, rodent infestation
B2	Three-Family Walk-Up	3 units	Emergency repairs, 311 requests
B3	Four-Family Walk-Up	4 units	Class B violations, leaks
C0	Three-Family with Stores	3 units	Commercial complaints, facade
C1	Four-Family with Stores	4 units	Storefront violations, boilers
C3	Five-Six Family with Stores	5-6 units	Noise, garbage issues
C4	Seven-Eight Family with Stores	7-8 units	Open permits, scaffolding
D0	Elevator Apartments, Non-Fireproof	10+ units	Local Law 11, sprinklers
D1	Elevator Apartments, Fireproof	10+ units	Accessibility features, audits
D3	Elevator Apartments, Semi-Fireproof	10+ units	Boiler inspections, vacate orders
D4	Elevator Apartments, Over 6 Stories	20+ units	Facade inspections, litigation
RA	Primarily Residence District Use	Varies	Zoning district mismatches

Consult the PLUTO dataset or BIS system for class details tied to BIN and BBL. Cross-check with HPD data for active violations specific to class type. This reveals risks in real estate records before purchase.

Year Built and Construction Info

PLUTO reports construction years and 12 construction types from balloon frame wood to steel skeleton. This data helps users assess a building's age and structural makeup through NYC Open Data. Check the year built field for key insights into potential updates or original features.

Common construction codes include 13-A for masonry and 1 for wood frame. These codes reveal fire safety implications, such as wood frames needing extra sprinklers in dense areas. Review them alongside DOB data for full context on risks.

Pre-1978 buildings often flag lead paint risks, a common issue in older NYC properties. Use the PLUTO dataset to cross-reference with HPD data on violations like class C issues. This step aids in evaluating health hazards before purchase or rental.

To analyze, search by BBL or BIN in the data portal, then filter for construction type. Combine with BIS system records for permits and complaints tied to the build era. Experts recommend noting these for insurance or renovation planning.

Number of Stories and Units

BIS/PLUTO reports residential units, commercial units, and stories for density calculations. These fields help users verify building scale in NYC Open Data. They draw from Department of Buildings records and PLUTO datasets.

The NumFloors field shows the number of stories, ranging from 1 to over 100 in high-rises. Use it to assess height and zoning district fit. For example, a 15-story building at BIN 1073919 indicates mid-rise residential use.

NumBldgs counts separate structures on a tax lot, often 1 for single buildings but higher for complexes. TotalUnits sums residential and commercial spaces, like 250 units in that Class A tower. Cross-check with certificate of occupancy for accuracy.

To verify FAR compliance, compare TotalUnits and NumFloors against zoning rules in PLUTO. Download CSV exports from the data portal for bulk analysis. This process reveals if a property matches its building class and primary land use.

Square Footage and Lot Size

PLUTO measures LotAreaSF (2,500-10M sq ft) and BldgAreaSF (500-4M sq ft) for 1:1 FAR ratio verification. These fields in the NYC Open Data PLUTO dataset provide essential property data for any building check. Use them to confirm if the structure fits zoning rules.

The FAR, or Floor Area Ratio, calculates as building square footage divided by lot size. This ratio shows development intensity in a zoning district. For example, a 25,000 sf lot with a 75,000 sf building yields a 3.0 FAR.

Residential zones set minimum lot sizes, like R6 requiring 1,800 sf per lot. Check the zoning district field in PLUTO alongside BBL (block and lot) for compliance. This helps verify if a tax lot supports the current building type.

To apply this in practice, download the PLUTO dataset CSV from the data portal. Filter by address, borough, block, and lot to pull square footage metrics. Cross-reference with DOB data for permits or violations tied to expansions.

Permit History and Status

The DOB Job Applications dataset on NYC Open Data tracks millions of records for building permits across the city. It reveals common permit statuses like Issued, Approved, and Expired. Use this data to assess a property's compliance history during a building check.

Search by Job#, such as 520123456, to view details like 'PLUMBING ALTERATION - ACTIVE' since 2023. This shows ongoing work and potential risks. Cross-reference with DOB NOW for recent digital submissions or legacy BIS system for older records.

Understanding permit status helps buyers spot open issues before purchase. For example, an Expired permit might need renewal. Always check the full history for patterns in violations or delays.

• Issued: Permit granted, work can start; verify inspections are scheduled.
• Approved: Plans accepted, issuance pending; monitor for final approval.
• Expired: Time limit passed, reapply if work incomplete; flag as risk.
• Active: Ongoing permit, site visits required; check progress reports.
• Finaled: Work complete and inspected; confirms compliance.
• Revoked: Canceled due to violations; investigate reasons.
• Denied: Application rejected; review for code issues.
• Pending: Under review; delays signal potential problems.

These statuses guide actions like requesting stop work orders or scheduling audits. Integrate with HPD data for a complete property profile on the data portal.

Violations and ECB Cases

The BIS Violation dataset on NYC Open Data logs cases from the Department of Buildings. It tracks DOB violations tied to building safety and code compliance. Check this dataset during a building check for full property data.

Violations fall into three classes based on severity. Class 1 covers immediate hazards like faulty fire escapes that may require evacuation. Class 2 includes serious issues such as illegal occupancy, while Class 3 handles general code violations like improper signage.

ECB cases link to the Environmental Control Board for fines and hearings. Use the ECB docket lookup in datasets to find open cases by BIN or BBL. For example, BIN 3729561 shows 7 open ECB violations totaling $18K in penalties.

• Search by building identification number (BIN) or address for quick matches.
• Review violation status, fine amounts, and resolution dates.
• Cross-check with HPD data for related class B or C violations on habitability.

Active violations signal risks for buyers or renters. Experts recommend verifying open permits alongside ECB cases. This reveals full compliance history in the BIS system.

Complaints Log

The DOB Complaint dataset on NYC Open Data holds over 750K records and averages 3 complaints per building, with 62% tied to construction noise and dust. This complaints log offers key insights into building issues reported to the Department of Buildings. Check it during your building search for patterns of problems.

Review the log by entering the address, BIN, or BBL in the NYC Open Data portal. It lists complaint dates, descriptions, status, and resolution details from the Building Information System. High volumes can signal ongoing maintenance concerns.

NYC DOB triggers inspections at 3+ complaints within a set period, leading to mandatory checks. For example, the building at 456 Amsterdam Ave has logged 28 complaints since 2018, mostly about noise and structural issues. Use this data to assess risk before buying or renting.

• Construction noise and dust dominate top complaints.
• Plumbing leaks and water damage rank high in volume.
• Structural safety concerns follow closely.
• Illegal conversions and occupancy violations appear frequently.
• Elevator malfunctions and fire safety lapses round out the top 10.

Filter the dataset by borough, block, lot, or complaint type for targeted views. Cross-reference with HPD data and 311 service requests to build a full picture of property conditions and owner responsiveness.

Certificate of Occupancy (CO)

BIS CO records verify legal occupancy for buildings on NYC Open Data. These records from the Department of Buildings Building Information System show if a structure matches its approved use. Missing COs often flag potential illegal conversions.

CO statuses include Active, Superseded, or None. An Active CO means the current certificate applies. Superseded indicates a newer one replaced it, while None suggests no record exists.

Occupancy classifications detail allowed uses, such as R-2 residential for multi-family homes or M-1 manufacturing for industrial spaces. For example, CO# 12345 might limit a building to 175 residential + 10 commercial units. Check these against current building class and square footage in the dataset.

When checking a building, search by BIN, BBL, address, borough, block, or lot. Cross-reference CO data with DOB data, violations, and permits for full compliance picture. This helps assess property data risks in real estate records.

Housing Maintenance Code Violations

HPD violations fall into Class B hazardous conditions like plumbing and heat issues, and Class C immediately hazardous ones such as no heat or water. These appear in NYC Open Data under HPD data when you check a building. Class B violations typically require correction within 21 days.

Review the violation codes in the dataset to spot patterns in building conditions. For example, Violation# 987654 shows 'NO HOT WATER' open for 45 days, signaling ongoing issues. Open violations can impact property valuation and rental safety.

Common top violations include rodent problems, lead paint hazards, and heat complaints. Use the data portal to filter by borough, block, lot, or BIN for precise property data. This helps assess risks before purchase or rental.

• Plumbing leaks: Class B, fix in 21 days, often linked to hot water issues.
• Rodent infestation: Class B, requires pest control within 21 days.
• Lead-based paint: Class C, immediate action needed for peeling surfaces.
• Inadequate heat: Class C, must resolve right away during cold months.
• Broken windows: Class B, secure within 21 days to prevent entry.

• No hot water: Class B, restore service in 21 days.
• Illegal occupancy: Class C, vacate or comply immediately.
• Fire hazards: Class C, eliminate risks without delay.

Cross-check with 311 service requests and complaints for full context on building profile. Active Class C violations may trigger emergency repairs or litigation, affecting real estate records.

Emergency Repair Program

The ERP dataset logs 28K annual emergency repairs costing taxpayers $165M, with an average of $6K per job. This NYC Open Data resource tracks repairs triggered by serious building violations. Owners face liens for reimbursement after city intervention.

Class B and Class C violations open over 20 days often activate ERP actions. These include issues like heat complaints, hot water problems, or rodent infestations from HPD data. Checking this in Building Check reveals repair history tied to your building identification number (BIN) or BBL.

The lien process starts with city-contracted work, followed by billing the owner at set rates. For example, at BIN 1073919, records show 15 ERP jobs since 2019 for problems like lead paint hazards and structural fixes. Use the dataset to filter by address, borough, block, and lot for precise property data.

Review DOB data alongside ERP logs for full context on violations, complaints, and permits. This helps assess risks in real estate records, such as ongoing class C violations impacting occupancy. Export CSV or use API access for deeper analysis on building conditions.

Lead-Based Paint Violations

Local Law 1 flags 420K pre-1978 buildings; HPD logs 12K annual lead violations averaging $8K fines. NYC Open Data provides detailed HPD data on these issues through building checks. Owners of older properties must test and abate lead paint to comply with city rules.

Lead testing and abatement requirements depend on building age. Structures built before 1978 face strict guidelines under Local Law 1. Check the year built in property data to assess if testing is needed.

Violation severity levels range from class B to class C in HPD violation data. Class C violations signal immediately hazardous conditions, like peeling lead paint. Tenants may gain relocation rights if severe issues persist without remediation.

For example, BIN 3341477 shows remediation completed in 2022 on NYC Open Data. Search by BIN or BBL in the data portal to view open violations, abatement status, and fines. This helps buyers review building conditions before purchase.

Harassment Complaints

The HPD harassment log on NYC Open Data tracks tenant complaints against landlords. It includes over 3.5K cases that can trigger emergency tenant protections and fines exceeding $10K. Checking this data helps reveal building conditions and potential risks.

NYC Open Data lists 7 harassment categories such as buyouts, illegal evictions, and tenant intimidation. Each entry shows the investigation timeline, often within 90 days. Use the building address or BBL to filter relevant records during your building check.

For example, the property at 456 Amsterdam Ave shows 3 open harassment cases in the HPD dataset. These cases link to HPD data on complaints and violations. Review them alongside DOB data for a full picture of property issues.

Access this through the data portal by searching harassment complaints datasets. Export in CSV for analysis or use API access for bulk checks. This building information supports informed decisions on real estate records and tenant protections.

Zoning District Code

PLUTO ZONEDIST1/2 fields code districts like R6 and C4-2 with base FAR limits. These fields in the NYC Open Data PLUTO dataset identify the primary and secondary zoning districts for each tax lot. They help users understand land use rules during a building check.

Zoning district codes dictate what can be built on a property. For example, R6 zones often apply to medium-density residential areas in Brooklyn. Check these codes to confirm if a building matches its permitted uses.

The top districts by parcel count include residential zones like R6, R4, and R5, plus commercial ones such as C1-2 and C4-2. Use the NYC Zoning Handbook for permitted uses and a zoning map lookup. This reveals details like height limits and lot coverage.

• R6B: Limits to 2.2 FAR, suits contextual rowhouses with gardens.
• C4-2: Allows mixed residential and commercial, common near transit.
• M1-1: Permits light manufacturing alongside some residential.
• R3-2: Focuses on one- and two-family homes with setbacks.
• C2-4: Neighborhood retail with apartments above.

Cross-reference zoning district data with DOB records for compliance. If mismatched, it may signal variances or illegal construction. This step refines your property data analysis.

FAR (Floor Area Ratio)

PLUTO reports allowable FAR from 0.35 to 15.0 versus actual FAR for each building. Some buildings exceed limits through variances. Check this data in NYC Open Data to understand zoning compliance during a building check.

The FAR formula calculates maximum floor area as lot area times the district's FAR value. For example, a 10,000 square foot lot in a 2.0 FAR district allows 20,000 square feet total. Bonuses like plazas add 20-33% more floor area in eligible zones.

Here are FAR examples for 10 common zoning districts:

• R3-1: 0.6 base FAR, low-density residential.
• R6: 2.2-3.0 base FAR, medium-density apartments.
• R10: 10.0 base FAR, high-rise residential.
• C1-2: 1.0 base FAR, neighborhood retail.
• C4-2: 2.0 base FAR, general commercial.
• C6-2.5 district: 6.5 base FAR + 1.0 bonus via plaza, totaling 7.5.
• C6-4: 4.0 base FAR, dense commercial.
• M1-1: 1.0 base FAR, light manufacturing.
• M2-1: 2.0 base FAR, heavy industrial.
• Special Midtown: up to 15.0 FAR with incentives.

Use PLUTO's zoning district and FAR fields with DOB data for full property analysis. Compare actual versus allowable to spot variances or overbuilds in real estate records.

Permitted Uses and Restrictions

Zoning Resolution Article II lists residential (R), commercial (C), and manufacturing (M) uses by district. When you check a building on NYC Open Data, the zoning district field reveals principal, accessory, and prohibited uses. This helps assess if current building activities align with rules.

Review the zoning district in the Building Information System (BIS) data or PLUTO dataset for specifics. For example, an R6 district allows multi-family dwellings as principal uses but bans industrial operations. Accessory uses might include home offices or community gardens.

District	Principal Uses	Accessory Uses	Prohibited
R6	Single or multiple dwellings	Garages, recreational facilities	Industrial, commercial retail
C1-2	Local retail stores, offices	Residential above stores	Manufacturing, heavy industry
M1-1	Light manufacturing, warehouses	Accessory offices	Residential dwellings

Use this table as a quick reference when exploring property data on the data portal. Cross-check with DOB data for open permits or violations tied to zoning misuse. Experts recommend verifying against the full Zoning Resolution for site-specific details.

Practical tip: Search by BBL or BIN in the BIS system to pull zoning info alongside complaints and ECB violations. This reveals if prohibited uses like unauthorized commercial space in residential zones trigger class B or C violations. Always confirm with current datasets for data freshness.

Special Districts/Overlays

PLUTO flags 68 special districts (TMU, MX) covering unique zoning areas with contextual height and form rules. These overlays appear in the zoning district field during a Building Check on NYC Open Data. They guide developers on restrictions tied to specific neighborhoods.

Each district enforces unique rules for building height, setbacks, and massing to preserve character. For example, the East Midtown Subdistrict caps towers at 1,200 feet to balance density and skyline views. Check the PLUTO dataset for flags like Special Midtown District or Theater District.

• Garment Center: Limits non-garment uses to protect manufacturing space.
• Special Clinton District: Controls tower heights near residential zones.
• Special Lincoln Square District: Regulates mixed-use developments for cultural sites.

• Special Harlem River Yards: Promotes waterfront industrial reuse.
• Special Willets Point District: Focuses on Queens stadium-area redevelopment.
• Special Coney Island District: Guides amusement and residential mix.
• Special South Street Seaport District: Maintains historic waterfront features.

Cross-reference these with DOB data or BIS system records for permit compliance. Use the data portal's filters on borough, block, lot, or BIN to spot overlays in property data.

Assessed Value

DOF assesses Class 1 at 6% of market value, Class 2-4 at 45%; median Brooklyn multifamily sits at $2.8M. This assessed value appears in NYC Open Data building checks under property valuation fields. It helps compare tax burdens across similar properties.

Assessment ratios vary by tax class, reflecting building type and use. For example, a market value of $10M for a Class 2 property equals $4.5M assessed using the 45% formula. Check the PLUTO dataset or tax rolls for exact ratios applied to your building's BBL.

Use assessed value with market value and exemption codes to gauge true worth. Class 1 owner-occupied homes get lower ratios for fairness. Review real property tax rolls on the data portal for updates and formulas.

Practical tip: Cross-reference assessed value from Building Information System with ACRIS deed records. Spot discrepancies in sales history or ownership changes. This informs investment decisions on tax class shifts or appeals.

Tax Class and Exemptions

NYC uses 42 tax classes and 300 exemption codes that reduce taxes for many properties, with 501(c)3 properties paying $0 in taxes. These details appear in the NYC Open Data datasets like PLUTO and tax assessment rolls. Checking a building reveals how its tax class and exemptions impact its assessed value and market value.

The top 10 tax classes cover most properties and include specific rules for valuation. For example, Class 1 handles one- to three-family homes and small parcels under 10,000 square feet. Class 2 covers all other residential like apartment buildings, with subclasses like 2B for rent-stabilized units that qualify for abatements of 17.5-45%.

Other key classes are Class 3 for utility property, Class 4 for commercial and industrial, and Class 5 for railroads. Use the Building Check on the data portal to filter by tax class, BBL, or address. This helps assess property valuation for real estate decisions.

• Class 1A: One-family homes with owner occupancy.
• Class 2A: Walk-up apartments under six stories.
• Class 4A: Primarily office buildings.
• Class 4B: Primarily retail.
• Class 4C: Primarily garage or parking lots.
• Class 4D: Primarily hotels or motels.
• Class 4E: Primarily theaters.
• Class 4F: Primarily golf courses.
• Class 4G: Other commercial or miscellaneous.
• Class 5: Railroad property.

Common exemptions include those for senior citizens and veterans, plus others like clergy, volunteers, and green roof incentives. Search exemption codes in the dataset by block and lot or BIN. Experts recommend reviewing these for accurate property data in transactions.

Annual Taxes and Billing

Property taxes bill quarterly; median Class A multifamily pays $185K/year at 11.7% rate. This data appears in NYC Open Data's property valuation records, including assessed value and market value. Check the PLUTO dataset for tax class and exemption codes tied to your building's BBL.

The tax rate formula multiplies assessed value by the class-specific rate set annually by the NYC Department of Finance. For example, a residential property in tax class 1 uses a lower rate than commercial class 4 buildings. Review building information in the data portal to confirm your tax lot details.

Billing follows a quarterly calendar: March 1 for July-September, June 1 for October-December, September 1 for January-March, and December 1 for April-June. Late payments trigger delinquency, with liens searchable via ACRIS for real property records. Use the building identification number to pull owner name and billing history.

To assess risks, search for ECB violations or HPD data alongside tax records, as unpaid taxes can lead to liens affecting sales history. Experts recommend cross-referencing with DOB data for open permits before purchase. This ensures clear title in your building check.

Market Value Estimates

DOF Market Value (AV / ratio) median $15M Manhattan; lags true values by 20-40%. This estimate comes from NYC Open Data's tax assessment rolls, where assessed value (AV) divides by the class ratio to approximate market worth. Check this in the PLUTO dataset or property valuation records for your building's BBL.

Sellers and buyers often spot appraisal gaps here, as DOF figures trail recent sales. Compare with ACRIS sales comps for nearby properties to gauge accuracy. For instance, a Manhattan condo at 123 Main Street might show $10M DOF value but $14M in recent ACRIS comps.
