Local Law 84 vs Local Law 95: What’s the Difference for NYC Building Owners?
If you own or manage a building in New York City, staying compliant with energy regulations is no longer optional. Local Law 84 and Local Law 95 are two major NYC energy compliance laws that directly affect thousands of commercial and residential buildings. Yet, many property owners still confuse the two.
At first glance, these laws may seem similar because both focus on building energy performance. However, they serve different purposes. One law requires benchmarking and reporting energy use, while the other focuses on public transparency by displaying a building’s energy grade.
Understanding the difference between Local Law 84 and Local Law 95 is essential if you want to avoid penalties, protect property value, and maintain compliance with NYC sustainability regulations.
This guide explains what each law means, who must comply, and how building owners can stay ahead of deadlines.
What Is Local Law 84?
Local Law 84 (LL84) is part of New York City’s Greener, Greater Buildings Plan. The law requires certain buildings to benchmark and report annual energy and water usage.
In simple terms, benchmarking means measuring how efficiently your building uses energy compared to similar properties.
Under Local Law 84, covered building owners must submit annual energy performance data through the ENERGY STAR Portfolio Manager, a platform developed by the U.S. Environmental Protection Agency.
The goal of LL84 is to help NYC understand how buildings consume energy and identify opportunities to reduce waste and carbon emissions.
Who Needs to Comply With Local Law 84?
Local Law 84 generally applies to:
- Buildings larger than 25,000 square feet
- Two or more buildings on the same tax lot totaling over 100,000 square feet
- Properties participating in city benchmarking requirements
If your building falls into these categories, annual reporting is mandatory.
Building owners must submit benchmarking data by May 1 each year. Missing deadlines can result in fines and compliance issues.

What Data Is Required for LL84 Compliance?
To comply with Local Law 84, building owners typically need to report:
- Electricity usage
- Natural gas consumption
- Water usage
- Fuel oil consumption
- Whole-building energy performance data
- Occupancy details
The City uses this information to evaluate energy performance trends across NYC buildings.
For many owners, gathering accurate utility data can become complicated, especially for multi-tenant commercial properties.
This is where professional energy compliance consultants often help streamline reporting and reduce errors.
What Is Local Law 95?
While Local Law 84 focuses on reporting data, Local Law 95 (LL95) is about public disclosure.
Under LL95, covered buildings must display an energy efficiency grade near the public entrance. The grade is based on benchmarking information submitted through Local Law 84.
Think of it like a restaurant health score—but for building energy performance.
The law assigns grades ranging from:
- A — High-performing, energy-efficient building
- B — Good energy performance
- C — Below-average performance
- D — Poor energy efficiency
Some buildings may receive an “N” grade if they are exempt or have insufficient data.
The purpose of Local Law 95 is simple: create transparency so tenants, investors, and the public can see how efficiently a building operates.

Who Must Comply With Local Law 95?
Most buildings covered under Local Law 84 are also subject to Local Law 95.
If your property is required to benchmark annually, you will likely need to post an energy grade in a visible public location.
The grade must be displayed:
- Near the building entrance
- Clearly visible to the public
- Following NYC Department of Buildings requirements
Failure to display the required grade can lead to financial penalties.
Local Law 84 vs Local Law 95: Key Differences
Although these laws work together, they are not the same.
1. Purpose of the Law
Local Law 84 focuses on collecting energy benchmarking data.
Local Law 95 focuses on making building performance visible to the public.
One is about reporting. The other is about transparency.
2. Compliance Requirement
Under LL84, owners must annually submit energy and water consumption information.
Under LL95, owners must publicly post an energy grade.
3. Deadline Responsibilities
For Local Law 84, annual reporting deadlines are critical.
For Local Law 95, building owners must ensure energy grades are displayed once issued.
4. Impact on Building Reputation
LL84 compliance happens mostly behind the scenes.
LL95 directly affects how tenants, investors, and visitors perceive your building.
A poor energy grade may influence leasing decisions, tenant confidence, and property marketability.
Why These Laws Matter for NYC Building Owners
Many owners assume Local Law 84 and Local Law 95 are simply administrative requirements. In reality, they can affect operating costs, tenant retention, and long-term building performance.
Here’s why compliance matters:
Lower Energy Costs
Benchmarking reveals inefficiencies.
When owners understand energy consumption patterns, they can make improvements that lower utility expenses.
Even small upgrades such as HVAC optimization or lighting improvements can reduce operational costs.
Better Building Reputation
Buildings with stronger energy grades often gain a competitive advantage.
Sustainability is becoming a priority for tenants, especially in commercial real estate markets across New York City.
An efficient building may attract environmentally conscious tenants and investors.
Avoid Costly Violations
Missing Local Law deadlines can trigger penalties.
Failure to benchmark under Local Law 84 or display grades under Local Law 95 may result in violations and unnecessary financial burdens.
Staying proactive is usually more affordable than correcting compliance mistakes later.
Preparation for Local Law 97
Another reason these laws matter is their connection to Local Law 97, NYC’s major carbon emissions regulation.
Building energy benchmarking data plays an important role in understanding future emissions performance.
Owners already complying with LL84 and LL95 are often better positioned to prepare for carbon caps under Local Law 97.
Common Mistakes Building Owners Make
Even experienced property owners make compliance mistakes.
Some common issues include:
Assuming LL84 and LL95 Are the Same
Many owners think posting an energy grade automatically satisfies benchmarking requirements.
It does not.
Local Law 84 reporting must happen first before a Local Law 95 grade can be generated.
Missing Annual Deadlines
Energy reporting deadlines are recurring.
Failing to submit updated benchmarking data can affect compliance status and energy grades.
Using Incomplete Utility Data
Inaccurate reporting may create compliance issues or lead to misleading energy scores.
Proper documentation is essential.
Waiting Until the Last Minute
Many building owners wait until deadlines approach.
This often creates stress, missing data problems, and reporting delays.
Working with experienced NYC compliance specialists can simplify the process.
