NYC Local Laws Every Building Owner Must Know in 2026

New York City has over one million buildings, and each one is subject to a web of overlapping compliance laws enforced by the Department of Buildings (DOB), Fire Department (FDNY), and Department of Environmental Protection (DEP). Missing a single filing deadline can trigger violations that cost thousands of dollars in fines, require emergency remediation, or even result in building access restrictions. For building owners, board members, and property managers, keeping track of every requirement across every law is one of the hardest parts of the job.

This guide covers every major local law that applies to NYC buildings in 2026 — what each law requires, who it applies to, what the penalties look like, and where to go for detailed guidance on each one.

Local Law 11 — Facade Inspections (FISP)

Local Law 11, officially the Facade Inspection and Safety Program (FISP), requires all buildings greater than six stories in height to have their exterior walls inspected every five years by a Qualified Exterior Wall Inspector (QEWI). The QEWI must be a licensed Professional Engineer or Registered Architect with at least seven years of relevant facade experience, accepted by the DOB to perform FISP inspections.

The current inspection cycle is Cycle 10, with filing deadlines staggered by the last digit of the building's tax block number across three sub-cycles. After inspection, the facade is classified as Safe, SWARMP (Safe With a Repair and Maintenance Program), or Unsafe. A single unsafe condition on any part of the exterior results in an Unsafe classification for the entire building, triggering immediate protective measures such as sidewalk sheds and expedited remediation.

Penalties for late filing start at $1,000 per month and escalate. Buildings with unresolved unsafe conditions face additional DOB violations, stop-work orders on other permits, and potential personal liability for building owners if a falling facade element causes injury. For a detailed breakdown of FISP requirements, inspection processes, and filing deadlines, see our [Local Law 11 guide](/guides/local-law-11).

Local Law 16 — Elevator Safety and Inspections

Local Law 16 expanded the regulatory framework for elevator safety in New York City, building on earlier requirements under Local Law 26. The law established more rigorous oversight of elevator maintenance, testing, and reporting, reflecting the city's focus on elevator safety after a series of high-profile incidents.

Under the current framework, all elevators in NYC require annual inspections by DOB-authorized inspectors, annual Category 1 (CAT1) no-load safety tests, and Category 5 (CAT5) full-load safety tests every five years. CAT1 tests verify that the elevator governor and safety devices function correctly at rated speed with an empty car. CAT5 tests are more demanding, evaluating safety devices under full rated load at governor tripping speed.

Building owners must maintain active maintenance contracts with DOB-licensed elevator companies, keep maintenance logs on-site in the machine room, and file inspection reports and Affirmations of Correction through DOB NOW. Penalties for non-compliance start at $1,000 per violation per month, and the DOB can order elevators out of service for serious safety deficiencies. For complete details on testing schedules, filing requirements, and penalties, see our [Local Law 26 guide](/guides/local-law-26).

Local Law 26 — Fire Alarm and Detection

Local Law 26 established fire alarm and detection requirements for commercial and residential buildings in New York City, with oversight by the FDNY. The law requires buildings to install and maintain fire alarm systems appropriate to their occupancy type, size, and use. Fire alarm systems must be inspected and tested annually by contractors holding an FDNY Certificate of Approval.

The FDNY has increased enforcement on fire alarm testing compliance, and buildings found with expired or missing test reports face immediate violations. For high-rise buildings, additional requirements apply including more frequent testing of emergency communications systems and witnessed testing by FDNY inspectors for certain system types.

Fire alarm inspections must follow NFPA 72 standards for inspection, testing, and maintenance, including annual functional testing of all devices, semi-annual battery load tests, and sensitivity testing of smoke detectors every two years. For fire alarm inspection and testing standards, see our [NFPA 72 guide](/guides/nfpa-72).

Local Law 87 — Energy Audits and Retro-Commissioning

Local Law 87 requires buildings over 50,000 gross square feet to undergo a comprehensive energy audit and retro-commissioning study every ten years. The audit identifies energy efficiency opportunities, while retro-commissioning evaluates existing building systems to ensure they operate at optimal efficiency without major capital investment.

The audit must be performed by a Professional Engineer or Registered Architect, and the results must be filed with the DOB. The retro-commissioning study includes a review of HVAC sequences of operation, lighting controls, domestic hot water systems, and building envelope performance. While building owners are not required to implement every recommendation, the process frequently identifies low-cost and no-cost improvements that reduce energy consumption by 10 to 20 percent.

LL87 compliance is closely connected to Local Law 97 (carbon emissions limits). The energy audit required under LL87 is often the first step in developing a compliance strategy for LL97, since it identifies the most cost-effective pathways to reducing building emissions. For the complete guide to LL87 requirements, audit scope, and filing deadlines, see our [Local Law 87 guide](/guides/local-law-87).

Local Law 97 — Carbon Emissions Limits

Local Law 97, enacted as part of the Climate Mobilization Act in 2019, sets greenhouse gas emissions limits for buildings over 25,000 gross square feet. It is one of the most ambitious building emissions laws in the world, covering approximately 50,000 properties and targeting an 80 percent reduction in building emissions by 2050.

The law establishes two compliance periods with progressively stricter caps. Period 1 (2024–2029) sets initial limits designed to target the worst-performing buildings — office buildings at 8.46 kgCO2e/sf/yr and multifamily residential at 6.75 kgCO2e/sf/yr. Period 2 (2030–2034) introduces significantly stricter limits — office buildings at 4.53 kgCO2e/sf/yr and multifamily at 3.35 kgCO2e/sf/yr — that will affect the majority of covered buildings.

The penalty for exceeding emissions limits is $268 per metric ton of CO2 equivalent over the limit, assessed annually with no cap. For a large office tower, this could mean penalties exceeding $1 million per year in the 2030 compliance period. Building owners should benchmark their emissions now, conduct energy audits, and plan capital improvements to meet the stricter Period 2 limits. For the complete LL97 guide including emissions thresholds by building type and compliance strategies, see our [Local Law 97 guide](/guides/local-law-97).

Local Law 152 — Gas Piping Inspections

Local Law 152 requires periodic inspection of gas piping systems in all NYC buildings served by gas. The inspection must be performed by a Licensed Master Plumber (LMP) or a qualified individual working under an LMP's direct supervision. The LMP must inspect all exposed gas piping from the point of entry to each gas utilization equipment connection using a portable combustible gas detector.

Inspections are required every four years, with deadlines staggered by community board district. After inspection, the LMP files a GPS-2 form with the DOB certifying the condition of the gas piping system. If an immediate safety threat is discovered — such as a gas leak — the LMP must notify the utility company (Con Edison) the same day and take appropriate measures to protect building occupants.

Non-compliance penalties can reach $10,000, and the DOB issues violations for both missed inspections and late filings. Building owners should schedule inspections well in advance of their community board deadline to avoid the rush period when LMP availability tightens. For complete details including the community board deadline schedule, inspection scope, and cost estimates, see our [Local Law 152 guide](/guides/local-law-152).

Which Laws Apply to Your Building

Not every law applies to every building. Here is a quick reference to help you determine which requirements are relevant to your property:

If your building is six stories or fewer, Local Law 11 (FISP) facade inspections do not apply. However, you are still responsible for maintaining fire escapes and exterior elements under the Building Code. If your building is under 25,000 gross square feet, Local Law 97 carbon emissions limits do not apply. If your building is under 50,000 gross square feet, Local Law 87 energy audits do not apply. If your building has no gas service, Local Law 152 gas piping inspections do not apply.

Elevator inspections apply to every building with elevators regardless of size. Fire alarm and detection requirements apply to all buildings with fire alarm systems. Boiler inspections apply to every building with a boiler.

For most mid-size to large buildings in NYC — particularly co-ops, condos, and commercial properties over six stories — all of these laws apply simultaneously, creating a complex compliance calendar that requires careful tracking and advance planning.

Beyond NYC — Tri-State Requirements

Building compliance does not stop at the NYC border. New Jersey and Connecticut have their own inspection and filing requirements that building owners and inspection companies must track. New Jersey follows the Uniform Fire Code, requiring annual fire safety inspections, state-licensed elevator inspections, and building energy benchmarking under the Clean Energy Act. Connecticut follows the NFPA 1 Fire Code with oversight by local fire marshals, plus its own elevator, boiler, and energy benchmarking requirements.

Companies that manage or inspect buildings across the tri-state area need to understand the specific requirements, enforcement agencies, and filing systems for each jurisdiction. For a comprehensive comparison of requirements across all three states, see our [Tri-State Compliance guide](/guides/tri-state-compliance).

Staying Compliant Across Every Law

The biggest risk for building owners is not any single law — it is the cumulative complexity of tracking deadlines, scheduling inspections, and filing reports across all of them simultaneously. A building that is fully compliant with FISP and LL152 but misses its LL87 energy audit filing still faces DOB violations. Compliance software that tracks every requirement, sends automated deadline alerts, and maintains a single source of truth for all buildings in a portfolio eliminates the gaps that manual tracking inevitably creates.
