Local Law 31 in NYC: The Complete 2026 Compliance Guide for Property Owners

You just received a notice from HPD about Local Law 31. Or your property manager mentioned an upcoming inspection requirement. Or maybe you’re buying a building and someone told you there’s a lead paint law you need to know about. Whatever brought you here, the question is the same: what exactly does Local Law 31 require, and what do you need to do about it? Local Law 31 is one of several NYC regulations designed to protect children from lead paint hazards. It mandates regular inspections of certain residential buildings by certified professionals, and the requirements have gotten stricter in recent years. This guide covers everything NYC property owners need to know about Local Law 31 compliance in 2026: which buildings are covered, what inspections involve, current deadlines, what happens if lead is found, and how to stay on the right side of the law.

What Is Local Law 31?

Local Law 31 of 2020 (LL31) requires owners of certain New York City residential buildings to conduct lead-based paint inspections at regular intervals. The law strengthened and expanded previous lead safety requirements, creating a comprehensive inspection and remediation framework. The core requirements:

• Covered buildings must be inspected for lead-based paint by EPA-certified inspectors
• Inspections must occur on a rotating cycle based on community district
• All dwelling units and common areas in covered buildings must be inspected
• Owners must file inspection reports with HPD
• Lead hazards identified during inspection must be remediated
• Records must be maintained and made available to tenants and HPD

Local Law 31 works alongside other NYC lead safety laws, including Local Law 1 of 2004 (which requires annual visual assessments and maintenance of lead-safe conditions) and the Lead-Safe Housing Law amendments. Together, these regulations create overlapping obligations that can confuse property owners, but LL31’s inspection requirement is distinct and carries its own compliance cycle. Why Local Law 31 exists: Lead poisoning remains a serious health threat to children, causing developmental delays, learning disabilities, and other permanent harm. NYC’s older housing stock, much of it built when lead paint was standard, creates ongoing exposure risks. Local Law 31 ensures that lead hazards are identified and addressed proactively, rather than waiting until a child is poisoned. The law reflects a shift from reactive to preventive regulation. Rather than responding only when elevated blood lead levels are detected, LL31 requires systematic inspection of at-risk buildings regardless of whether problems have been reported.

Which Buildings Must Comply with Local Law 31?

Not every NYC building falls under Local Law 31. The law targets residential properties most likely to contain lead paint and house young children. Covered buildings: Local Law 31 applies to multiple dwellings (buildings with three or more residential units) that meet either of these criteria:

1. Built before 1960, OR
2. Built between 1960 and 1978 where a child under age 6 resides

For buildings constructed before 1960, the inspection requirement applies to the entire building regardless of whether children currently live there. The age of the building creates a presumption of lead paint presence. For buildings constructed between 1960 and 1978, the requirement is triggered by child occupancy. Owners must know whether young children reside in their buildings to determine compliance obligations. Exempt properties:

• Single-family homes (1 unit)
• Two-family homes (2 units)
• Buildings constructed in 1978 or later
• Buildings where all units have been certified lead-free through proper testing and documentation

Common ownership scenarios:

Property Type	LL31 Applies?
10-unit apartment building built in 1950	Yes: pre-1960 multiple dwelling
4-unit building built in 1965, no children	No: post-1960, no child under 6
4-unit building built in 1965, child in unit 2	Yes: post-1960 with child under 6
2-unit brownstone built in 1920	No, not a multiple dwelling
Condo building built in 1955 (50 units)	Yes: pre-1960 multiple dwelling

Important note on child occupancy: Building owners are required to annually inquire whether children under age 6 reside in their units. This inquiry triggers obligations under both Local Law 31 and Local Law 1. If you own a post-1960, pre-1978 building and haven’t been conducting annual occupancy inquiries, you may be out of compliance regardless of inspection status. If you’re unsure whether your building requires Local Law 31 inspection, a quick consultation with a certified inspector can clarify your obligations before HPD does it for you.

What Does a Local Law 31 Inspection Include?

Local Law 31 inspections are comprehensive surveys of lead-based paint presence throughout covered buildings. They must be performed by EPA-certified lead-based paint inspectors or risk assessors. Scope of inspection: The inspection covers all painted surfaces in:

• Every dwelling unit in the building
• All common areas (hallways, stairwells, lobbies, laundry rooms, etc.)
• Building exterior components (porches, railings, window frames visible from common areas)

Within each space, inspectors test painted components including:

• Walls and ceilings
• Window frames, sills, and wells
• Door frames and doors
• Baseboards and trim
• Radiators and pipes
• Cabinets and shelving
• Any other painted building component

Testing methodology: Most Local Law 31 inspections use XRF (X-ray fluorescence) testing, a non-destructive method that provides immediate results. The inspector holds a handheld device against each painted surface, and the device measures lead content in milligrams per square centimeter. Surfaces with lead content at or above 1.0 mg/cm² are classified as lead-based paint under federal standards. XRF testing allows inspectors to survey hundreds of components efficiently without damaging surfaces or collecting samples. For a typical apartment, inspection takes 30-60 minutes. Larger units and buildings with complex trim work take longer. What you’ll receive: After inspection, you’ll receive a detailed report documenting:

• Every component tested
• Location of each component (unit, room, wall)
• XRF reading for each component
• Classification (positive or negative for lead-based paint)
• Summary of findings by unit and common area
• Recommendations for any lead hazards identified

This report becomes part of your compliance documentation and must be filed with HPD according to the established schedule. Tenant access requirements: Inspectors need access to all dwelling units. As a building owner, you’re responsible for providing this access, which often means coordinating with tenants. HPD recommends providing advance notice and flexible scheduling options to ensure all units can be inspected. Units that cannot be accessed during the initial inspection visit may require follow-up, adding time and cost to the process. Proactive tenant communication helps avoid these delays.

Local Law 31 Compliance Deadlines and Inspection Cycles

Local Law 31 established a rolling inspection cycle based on community district. Your compliance deadline depends on where your building is located. The four-year cycle: All covered buildings must complete LL31 inspections within a four-year cycle. NYC’s 59 community districts are divided into four groups, with approximately one-quarter of districts due each year. Current cycle (Cycle 2):

Year	Community Districts Due
2025	Districts in the Bronx, Brooklyn, Manhattan, Queens, Staten Island (Group 1)
2026	Group 2 districts
2027	Group 3 districts
2028	Group 4 districts

To find your specific deadline, check HPD’s community district lookup tool or contact HPD directly with your building’s address. The deadline for filing your inspection report is typically the last day of the calendar year for your assigned year. What “compliance” means: Meeting your Local Law 31 deadline requires:

1. Complete the inspection of all units and common areas by a certified inspector
2. File the inspection report with HPD through the HPD Online portal
3. Address any lead hazards identified during inspection (see next section)
4. Maintain records of inspection and any remediation work

Simply scheduling an inspection isn’t enough, the report must be filed with HPD by your deadline. Late filings result in violations and potential penalties. Missed deadlines: If your building’s deadline has passed and you haven’t filed, you’re already in violation. HPD can issue violations, impose fines, and in some cases order emergency inspections at owner expense. The best course of action is to complete inspection and filing as quickly as possible, continued non-compliance increases penalties. Ongoing obligations: Local Law 31 isn’t a one-time requirement. After your initial inspection, you’ll need to complete subsequent inspections in each four-year cycle. The inspection and filing process repeats indefinitely for covered buildings. Between LL31 inspection cycles, you’re still obligated under Local Law 1 to:

• Conduct annual visual assessments for deteriorating paint
• Perform annual tenant inquiries about child occupancy
• Maintain lead-safe conditions through proper turnover protocols
• Address any deteriorating paint promptly

What Happens If Lead Paint Is Found?

Finding lead paint in your building doesn’t automatically mean expensive remediation. The response depends on the condition of the paint and the specific components affected. Lead paint in good condition: Intact lead paint that isn’t deteriorating, peeling, or chalking can often be managed in place. The law doesn’t require removal of all lead paint, it requires that lead paint hazards be controlled. For intact lead paint, ongoing management includes:

• Regular monitoring for deterioration
• Safe maintenance practices when working near lead paint
• Proper protocols during tenant turnover
• Documentation of paint condition

Deteriorating lead paint: Paint that is peeling, chipping, flaking, or chalking creates a lead hazard that must be addressed. Under NYC law, deteriorating lead paint must be remediated using lead-safe work practices by trained workers. Remediation options include:

• Repair and stabilization: Scraping loose paint, priming, and repainting using lead-safe methods
• Enclosure: Covering lead paint with durable materials (drywall, paneling)
• Encapsulation: Applying specialized coatings that seal lead paint in place
• Removal: Complete removal of lead paint (most expensive, not always necessary)

The appropriate method depends on paint condition, component type, and building circumstances. A qualified inspector can recommend approaches based on your specific findings. Friction and impact surfaces: Certain surfaces receive special attention regardless of paint condition:

• Friction surfaces: Windows, doors, and other components where painted surfaces rub together
• Impact surfaces: Areas subject to repeated contact (door edges, stair treads, baseboards in high-traffic areas)

These components generate lead dust through normal use even when paint appears intact. NYC law requires that friction and impact surfaces with lead paint be addressed during turnover and may require attention even outside turnover situations. Remediation timeline: When lead hazards are identified during a Local Law 31 inspection, you’re required to remediate within specific timeframes, generally before the next inspection cycle, but potentially sooner for serious hazards. HPD violations for hazardous conditions carry their own correction deadlines. Documentation requirements: All remediation work must be documented and records maintained. This includes:

• Scope of work performed
• Methods and materials used
• Clearance testing results (when required)
• Worker certifications

This documentation becomes part of your ongoing compliance record and may be requested by HPD or during property transactions. UNYSE provides both Local Law 31 inspection and remediation consulting services, helping property owners understand their obligations and develop practical compliance strategies.

Local Law 31 Penalties: What Non-Compliance Costs

HPD takes lead safety seriously, and penalties for Local Law 31 violations reflect that priority. Understanding the potential costs helps frame the value of proactive compliance. Violation classes and fines: Local Law 31 violations are typically classified as follows:

Violation Type	Classification	Penalty Range
Failure to file inspection report	Class C (immediately hazardous)	$1,000–$2,500 per month
Failure to remediate lead hazards	Class C	$1,000–$2,500 per month
Failure to maintain records	Class B	$250–$500
Failure to provide tenant notice	Class A/B	$250–$1,000

Escalation for continued non-compliance: Fines aren’t one-time assessments. Class C violations accrue penalties for each month they remain uncorrected. A building with an unfiled inspection report could face thousands of dollars in accumulated fines before the situation is resolved. HPD can also:

• Order emergency inspections performed by city contractors at owner expense
• Place liens on properties for unpaid fines
• Refer egregious cases for criminal prosecution
• Publicize non-compliant buildings, affecting reputation and tenant relations

Beyond financial penalties: Non-compliance creates risks beyond fines:

• Liability exposure: If a child is lead-poisoned in a building where required inspections weren’t performed, the owner faces significant legal liability
• Transaction complications: Buyers and lenders increasingly require LL31 compliance documentation; violations can delay or derail sales
• Insurance issues: Some policies exclude coverage for lead-related claims when owners haven’t maintained compliance
• Tenant relations: Tenants have access to violation records and may use non-compliance as leverage in disputes

The cost of compliance vs. Non-compliance: A Local Law 31 inspection for a typical NYC apartment building costs $500–$2,000 depending on size. Even including potential remediation costs, proactive compliance is almost always less expensive than accumulated penalties, emergency inspection orders, and legal exposure from non-compliance.

How to Schedule a Local Law 31 Inspection

Ready to get compliant? Here’s how to move from concern to completed filing. Step 1: Verify your obligations Confirm that your building requires Local Law 31 inspection:

• Is it a multiple dwelling (3+ units)?
• Was it built before 1960, OR built 1960-1978 with a child under 6 in residence?

If yes to both questions, you need LL31 inspection. Step 2: Find your deadline Check which community district your building is in and when your inspection cycle deadline falls. HPD’s website provides lookup tools, or you can call HPD directly. Step 3: Choose a qualified inspector Local Law 31 inspections must be performed by EPA-certified lead-based paint inspectors or risk assessors. Verify credentials before hiring:

• Current EPA certification (TSCA Section 402)
• Experience with NYC Local Law 31 requirements
• Proper XRF equipment and calibration
• Clear pricing and scope documentation

Ask for references from other NYC building owners and confirm the inspector can meet your timeline. Step 4: Coordinate tenant access You’ll need to provide access to every dwelling unit. Notify tenants in advance, offer flexible scheduling windows, and follow up with any units that can’t be accessed initially. Step 5: Complete inspection and receive report The inspector will survey all units and common areas, then provide a detailed report of findings. Review the report for accuracy and clarify any questions about the results. Step 6: File with HPD Submit your inspection report through HPD Online by your deadline. Keep confirmation of filing for your records. Step 7: Address any lead hazards If the inspection identifies lead hazards requiring remediation, develop a plan to address them within required timeframes. This may involve hiring certified renovation contractors or lead abatement professionals. Step 8: Maintain ongoing compliance Remember that Local Law 31 is cyclical. Mark your calendar for the next inspection cycle and continue meeting your Local Law 1 obligations (annual assessments, tenant inquiries, turnover protocols) in the meantime.
