Understanding Local Law 87 Requirements

What Building Owners Need to Know About Local Law 87 Requirements

LL87 is a New York City energy-efficiency law requiring qualifying properties to undergo an energy audit and retro-commissioning on a ten-year cycle. The owner must then submit electronic compliance documents describing the audit and retro-commissioning results. The purpose of these requirements is to help owners understand energy consumption and ensure existing systems function properly. :contentReference[oaicite:0]index=0

Compliance begins by verifying that the property meets the law’s coverage criteria. According to Department of Finance records, covered properties generally include individual buildings exceeding 50,000 gross square feet. The law also covers multiple buildings on the same tax lot with a combined gross area above 100,000 square feet. In addition, it can apply to qualifying condominium building groups whose combined area is greater than 100,000 square [https://iagenergy.com/new-york-local-law-87/ local law 84 compliance consulting] feet. :contentReference[oaicite:1]index=1

The most dependable way to confirm an obligation is to review the City’s current covered-building records. Informal measurements or old property documents may contain outdated square-footage or ownership details. Certain Class 1 properties are exempt, including some one-, two-, and three-family dwellings and qualifying low-rise condominiums. Owners who believe a listed building is exempt should confirm the property classification before ignoring a filing requirement. :contentReference[oaicite:2]index=2

The second major requirement is identifying the correct filing year. A building’s filing year is generally connected to the last digit shown in the property’s tax block. The owner must submit the EER before the end of the assigned compliance year, with the obligation recurring every decade. Because the work may involve record collection, inspections, testing, repairs, professional review, and electronic filing, owners should begin months before the deadline rather than waiting until the final weeks. :contentReference[oaicite:3]index=3

LL87 requires a systematic review of how the covered building consumes energy. The audit must examine the building’s energy performance and potential energy conservation measures. Systems reviewed may include major mechanical and electrical systems that consume or influence energy. The audit should produce a structured list of potential improvements, estimated savings, implementation considerations, and other required technical information. :contentReference[oaicite:4]index=4

The audit must be detailed enough to meet the City’s required level of analysis. The original law describes an audit that is no less stringent than the referenced ASHRAE Level II energy survey and engineering analysis. The professional may need to collect documents that explain how the building is designed and operated. Site inspections and interviews with building personnel can help verify operating conditions and identify problems that records alone may not reveal. :contentReference[oaicite:5]index=5

Retro-commissioning is another mandatory component of LL87. Retro-commissioning verifies that systems are working correctly and meeting the owner’s present operational needs. The process may identify operational deficiencies that waste energy even when equipment remains functional. Required corrections generally must be completed and documented as part of the retro-commissioning process. :contentReference[oaicite:6]index=6

Building owners cannot rely solely on ordinary maintenance staff to complete the compliance documentation. The energy auditor and retro-commissioning agent must satisfy current City requirements for technical competence and professional responsibility. Owners should verify that the consultant understands both engineering requirements and electronic filing procedures. Selecting an experienced team can make the compliance process more efficient and dependable. :contentReference[oaicite:7]index=7

The final filing requirement is an acceptable EER submitted electronically to the Department of Buildings. The EER consists of the forms and technical materials required by current DOB instructions. Available forms include the EERC1 certification for the energy auditor and owner and the EERC2 certification for the retro-commissioning agent and owner. Owners should use the latest City-issued forms and filing guidance. :contentReference[oaicite:8]index=8

Hiring an energy auditor does not transfer the entire legal obligation away from the owner. Owner responsibilities may include providing accurate building information, arranging site access, supplying records, reviewing findings, authorizing corrective work, signing certifications, and paying filing fees. Owners should retain organized documentation showing what work was completed and when. Good recordkeeping can provide evidence of compliance if City records are disputed. :contentReference[oaicite:9]index=9

Some properties may qualify for special treatment under limited circumstances. Eligibility can depend on the particular facts and documentation associated with the property. These provisions are subject to detailed eligibility and filing requirements. An owner seeking a deferral or extension may need to submit an application, supporting evidence, certifications, and applicable fees. :contentReference[oaicite:10]index=10

Owners must also respond appropriately to any LL87 violations. Beginning with violations associated with the December 31, 2024 deadline and future deadlines, civil-penalty payments and challenge requests are handled through DOB NOW: Safety. An owner who believes a violation was issued incorrectly should follow the official challenge procedure and provide supporting documentation within the required timeframe. Starting work after the deadline does not necessarily replace the need to file the required report. :contentReference[oaicite:11]index=11

LL87 requirements focus on both identifying improvements and correcting operational deficiencies. The energy audit identifies possible energy conservation measures and future investment opportunities. Retro-commissioning addresses deficiencies that may be corrected through calibration, repair, adjustment, or programming. Although LL87 does not necessarily require implementation of every energy conservation measure recommended by the audit, required retro-commissioning corrections must be addressed as part of the compliance process. :contentReference[oaicite:12]index=12

Compliance with Local Law 87 does not automatically satisfy every building-energy requirement. A building may have several sustainability requirements that must be managed independently. The LL87 EER is generally required once every ten years, while other programs may require annual reporting or separate physical improvements. Coordinating these obligations can help owners use audit findings to support broader energy and capital-planning goals. :contentReference[oaicite:13]index=13

Ultimately, the main LL87 requirements are to confirm that a property is covered, determine its filing year, complete a compliant energy audit, perform retro-commissioning, correct applicable deficiencies, and submit an acceptable EER. Successful compliance depends on early planning, qualified professionals, accurate building records, proper documentation, and timely filing. Because forms, procedures, and administrative systems may be updated, owners should rely on the latest official instructions available for their filing year. :contentReference[oaicite:14]index=14
