Download the full LL11 guide to understand inspection requirements, filing timelines, and how to plan for necessary repairs, plus:
Local Law 11, also known as the Façade Inspection & Safety Program (FISP), requires periodic inspections of building exteriors to ensure they are safe and properly maintained.
The law focuses on identifying conditions such as cracks, loose materials, or deterioration that could pose a risk to public safety.
Buildings that are 7 stories or taller
Retain a Qualified Exterior Wall Inspector (QEWI)
Perform a façade inspection, including a critical examination of exterior walls and appurtenances
Classify the building’s condition (Safe, Safe with a Repair and Maintenance Program (SWARMP), or Unsafe)
File an inspection report with the NYC Department of Buildings
Compliance Cycle: Every 5 years, based on assigned building cycle
Buildings classified as Unsafe require immediate protective measures and repairs, while SWARMP conditions must be corrected within the required timeframe or may be reclassified as Unsafe
LL11 compliance involves coordinating an inspection, documenting conditions, and filing the required report with the DOB.
The inspector evaluates exterior walls and appurtenances, identifies any unsafe conditions, and assigns a classification based on the building’s condition.
If repairs are required, they must be completed and, in some cases, re-inspected before final compliance is achieved.
LL11 is often treated as a routine inspection, but the real challenge comes when conditions are identified that require repairs.
In practice, many buildings:
This often results in higher costs, limited contractor availability, and increased pressure to complete repairs quickly. Missed filings and delayed repairs can also lead to violations, ongoing penalties, and increased project costs.

Download the full LL33/95 guide to understand how your building’s energy grade is calculated and what impacts your score, plus:
Local Law 33 (updated by Local Law 95) requires certain NYC buildings to publicly display an energy efficiency grade based on their annual benchmarking data.
Each building receives a letter grade (A through F), similar to a restaurant inspection grade, which reflects its ENERGY STAR score and overall energy performance.
Deadline: Grades must be displayed each year by October 31 (the grades are typically made available by the DOB on October 1)
LL33/95 relies directly on benchmarking data submitted under Local Law 84.
Once benchmarking is completed and the DOB has processed the information, they assign a letter grade (this typically occurs on October 1) based on the building’s ENERGY STAR score. The building owner must then download the official grade label, print it out, and display it in a visible location near the main entrance.
Many buildings assume this is just a posting requirement, but the grade itself often creates real pressure.
In practice, buildings:
Because the grade is visible to the public, it can influence perception, tenant expectations, and decision-making.

Download the full LL87 guide to understand audit scope, retro-commissioning requirements, and how to plan your compliance timeline, plus:
Local Law 87 requires certain NYC buildings to complete an energy audit and retro-commissioning study every ten years. The goal is to identify energy-saving opportunities and confirm that existing building systems are operating efficiently. An energy audit analyzes where energy is being used and where it can be reduced, while retro-commissioning focuses on testing and optimizing existing systems.
The filing year is based on the last digit of the building’s tax block number, and the report is due by December 31 of that assigned compliance year.
LL87 compliance typically involves evaluating major building systems, identifying operational inefficiencies, and documenting recommended improvements in an Energy Efficiency Report. DOB provides reporting forms, an energy audit template tool, and a retro-commissioning reporting tool for submission. Completed EER filings are submitted to [email protected].
Many buildings work with a Registered Design Professional or qualified energy consultant to complete the audit, retro-commissioning, and required reporting accurately. DOB also allows certain buildings to apply for an extension or deferral under specific circumstances.
LL87 is often treated like a one-time filing requirement, but in practice it tends to surface deeper operational issues. This is often where buildings discover that systems are no longer performing as intended, controls are out of sync, or prior upgrades were never fully optimized. Because it is only required every ten years, many buildings wait too long to prepare and end up compressing both analysis and implementation into a much shorter timeline than they should. This is an inference based on the law’s ten-year cycle and the audit/retro-commissioning requirements.

Download the full LL55 guide to evaluate infrastructure requirements and plan EV charging implementation, plus:
Local Law 55 (2024) requires certain NYC buildings with parking facilities to install electric vehicle (EV) charging infrastructure.
This includes installing a minimum number of Level 2 EV chargers and making additional parking spaces “EV-ready” to support future charger installation.
Compliance typically involves evaluating the building’s electrical capacity, upgrading infrastructure where needed, and installing EV chargers
This often requires coordination between engineers, electricians, and utility providers to determine load capacity and upgrade requirements.
Many buildings underestimate the complexity of infrastructure upgrades required to support EV charging.
In practice, challenges often include:
Buildings that plan early are better positioned to avoid costly upgrades and delays.

Download the full LL97 guide to understand your emissions limits, potential penalties, and available compliance strategies, plus:
Local Law 97 sets annual carbon emissions limits for large buildings in New York City.
Instead of focusing on reporting or system upgrades alone, this law requires buildings to reduce emissions over time or face financial penalties. Emissions are calculated based on energy usage, space types, and specific emissions factors tied to fuel types.
Deadline: May 1 each year, with an automatic grace period through June 30th.
Buildings that exceed their emissions limit are subject to penalties.
LL97 compliance requires collecting building energy data, applying emissions factors, and calculating total annual emissions.
This process is typically completed using benchmarking data (LL84) and supporting analysis. It is required that buildings work with a Registered Design Professional (RDP) to sign off on the calculations, reporting, and filing.
Buildings must submit an annual report through the DOB platform confirming emissions and compliance status.
LL97 is often misunderstood as a single compliance requirement, when in reality it is an ongoing performance standard.
In practice, many buildings:
Because limits become stricter over time, decisions made today can significantly impact future compliance costs.

Download the full LL88 guide to determine what upgrades are required and how to properly document compliance, plus:
Local Law 88 requires covered NYC buildings to upgrade lighting systems to current energy code standards and install electrical sub-meters in covered tenant spaces. In practice, this law is about improving lighting efficiency, adding required controls, and increasing visibility into tenant electricity usage.
The DOB page also lists key exceptions, including certain one-, two-, and three-family homes, some garden-style apartments, and dwelling units in occupancy groups R-2 and R 3.
For sub-metering, covered tenant spaces include spaces larger than 5,000 gross square feet occupied by one tenant, or a floor larger than 5,000 gross square feet occupied by multiple tenants.
Deadline: LL88 reports are due May 1 annually until compliance is met.
For lighting, DOB requires an attestation of compliance confirming that the building’s lighting system has been inspected and upgraded in accordance with the law. For sub-metering, filing includes an attestation of compliance, a list of covered tenant spaces, and sample monthly statements for each tenant or sub-meter, if applicable. These attestations must be certified by a registered design professional or a licensed master or special electrician and then submitted through the BEAM portal and currently require a $115 filing fee.
LL88 is often viewed as a simple lighting project, but it becomes more complex once buildings evaluate which spaces are covered, what documentation exists, and whether prior upgrades meet current requirements.
Buildings that wait too long are often forced to act quickly, limiting their ability to explore options and leading to higher costs or unnecessary upgrades. Delays can also mean complying under newer, more stringent energy code requirements, further increasing project scope and cost.

Download the full LL84 guide to see exactly how to complete your benchmarking submission and avoid common reporting issues, plus:
Local Law 84 requires certain NYC buildings to track and report their annual energy and water usage. This is done through the ENERGY STAR Portfolio Manager system and submitted to the NYC Department of Buildings each year.
Rather than focusing on upgrades, this law is about measuring building performance and establishing a baseline for future compliance requirements.
Deadline: May 1 each year
Benchmarking requires organizing building data such as square footage, usage types, and energy and water consumption, then submitting it through ENERGY STAR Portfolio Manager.
Many buildings work with a Registered Design Professional (RDP), such as a Professional Engineer or Registered Architect, to help ensure the data is accurate and properly filed.
Many buildings treat benchmarking as a routine filing, but overlook its role in long-term planning.
In practice, this is often where:
