Building Performance Standards by City: A Complete Comparison

NYC has one set of rules. DC has another. Boston does it differently again. If you own buildings in more than one city, you're tracking multiple systems with different deadlines, different limits, and different penalty structures.

It's a mess. But it's the reality. At least 40 cities and states have passed or proposed building performance standards, and each one works a little differently. This guide puts the five biggest ones side by side so you can see exactly what you're dealing with.

What Are Building Performance Standards?

Building performance standards (BPS) are laws that set energy or emissions limits for existing buildings. Not new construction. Not major renovations. Buildings that are already standing and operating right now.

The basic idea is the same everywhere: measure your building's energy use or carbon emissions, compare it to a limit, and face penalties if you're over. But the specifics vary wildly between cities.

Some laws use Energy Use Intensity (EUI) as the metric. Others use carbon emissions. The thresholds, timelines, and penalty structures are all different. You can't just apply one strategy across your whole portfolio. You need to understand each law on its own terms.

Now let's dig into each one. Because the devil is absolutely in the details.

NYC Local Law 97

New York's law is the biggest and most aggressive building performance standard in the country. It covers roughly 50,000 buildings and uses carbon emissions as the compliance metric.

The first compliance period (2024 to 2029) has relatively achievable limits. A typical office building needs to stay under about 8.46 kg CO2e per square foot. Most decent buildings can hit that without major work.

The real problem is 2030. That same office building limit drops to roughly 4.53 kg CO2e per square foot. That's nearly a 50% cut. A lot of buildings that are comfortable today will be way out of compliance.

The penalty: $268 per metric ton of CO2 over your limit, every year. For a 200,000 sqft building that's 400 tons over, that's $107,200 annually. We break this down in detail in our complete guide to LL97 penalties.

Filing is annual, due May 1st. The city is actively enforcing. This is not a suggestion.

Washington DC BEPS

DC's Building Energy Performance Standards apply to buildings over 10,000 square feet. That's a much lower threshold than anywhere else. If you own smaller commercial properties in DC, pay attention.

DC uses a two-track approach. If your building's ENERGY STAR score is below the median for your property type, you either need to meet a performance standard or show a 20% improvement in energy performance over a five-year compliance cycle.

Timeline

The first compliance cycle begins in 2026 for the largest buildings (over 50,000 sqft that scored below the median). Smaller buildings phase in over later cycles.

Penalties

Instead of a per-ton carbon fine, DC charges up to $10 per square foot spread over five years for non-compliance. For a 100,000 square foot building, that could add up to $1 million over the compliance cycle.

DC's alternative compliance pathway: You can submit an approved action plan showing the steps you'll take to improve, even if you can't meet the target right away. The plan has to be credible, and the improvements have to actually happen. But it buys you time.

Washington State Clean Buildings Act

This one's different because it's a state-level standard, not a city ordinance. It applies to all commercial buildings over 20,000 square feet across the entire state of Washington.

The metric is EUI (Energy Use Intensity), not carbon emissions. Your building has to meet an EUI target based on its type. If you're over, you need to implement energy management measures to bring consumption down.

Timeline

  • Buildings over 50,000 sqft: First compliance deadline was June 2026
  • Buildings 20,000 to 50,000 sqft: Deadline is June 2028

Penalties

A $5,000 base fine plus up to $1 per square foot. For a 100,000 square foot building, the max penalty is $105,000. Lower than NYC or DC, but still real money.

Important detail: Washington requires an energy management plan even if your building already meets the EUI target. Not having a plan on file is itself a violation. Don't skip this.

Boston BERDO 2.0

Boston's Building Emissions Reduction and Disclosure Ordinance covers buildings over 20,000 square feet or with 15 or more residential units. That pulls in about 3,500 buildings.

Like NYC, Boston uses greenhouse gas emissions as the metric. Buildings must meet declining emissions targets on a five-year cycle, with the first compliance check in 2025 and net-zero required by 2050.

Penalties

$234 per ton of CO2 over the limit. Slightly less than NYC's $268, but still substantial. A multifamily building 100 tons over its limit faces $23,400 per year.

Alternative Compliance

Boston created "Alternative Compliance Credits" that work like renewable energy certificates but are specific to the BERDO framework. You can buy credits to cover a portion of excess emissions instead of making all improvements on-site.

There's also a hardship exemption for buildings where compliance costs would be "unreasonable" relative to the building's value. This mostly applies to smaller, older buildings. If you own a Class A office tower, don't count on it.

Denver Energize Denver

Denver's ordinance covers buildings over 25,000 square feet. The city uses EUI-based performance targets that vary by building type and get stricter over time.

Timeline

  • 2024: First compliance period started
  • 2027: Interim targets kick in
  • 2030: Final targets in effect

Penalties

$0.70 per square foot annually for non-compliant buildings. For a 100,000 square foot building, that's $70,000 per year. Denver also requires annual energy benchmarking through ENERGY STAR Portfolio Manager.

Denver's big push is electrification. The city's climate action plan prioritizes getting buildings off natural gas. The EUI targets are structured to reward all-electric buildings. If you're planning improvements in Denver, electrification should be central to your strategy.

Key Takeaways for Multi-City Owners

If you own buildings in more than one city, here's what you need to have straight:

The Metrics Aren't the Same

NYC and Boston use carbon emissions. DC uses ENERGY STAR scores. Washington State and Denver use EUI. You can't run the same analysis everywhere. A building that's compliant on one metric might be out on another.

Thresholds Vary Wildly

DC catches buildings as small as 10,000 square feet. NYC and Denver start at 25,000. A building that's exempt in one city might be regulated in another.

Timelines Overlap

You might have compliance deadlines in multiple cities hitting in the same year. If you're not planning your capital budget across your whole portfolio, you're going to get surprised.

Penalties Stack Up Fast

A portfolio with 10 non-compliant buildings across three cities could face combined annual penalties in the hundreds of thousands or millions of dollars. That's not an exaggeration. Run the numbers.

One tool, every city: Instead of tracking each law separately, use BPS Check to see your compliance status across every major building performance standard in one place. Enter your building data once. See where you stand everywhere.

More Laws Are Coming

This isn't a temporary trend. St. Louis, Chula Vista, Ann Arbor, and Montgomery County (Maryland) have all passed or proposed their own building performance standards. The federal government has signaled support through the DOE's BPS Coalition.

If your city doesn't have a BPS law yet, it probably will within the next few years. The smart move is to start benchmarking and improving now, before a law forces you to do it on a deadline with penalties attached.

Start With Your Data

Every building performance standard starts with the same thing: knowing your building's energy consumption and emissions. If you don't have reliable benchmarking data, nothing else matters.

Get your numbers. Check your compliance status across every jurisdiction that applies. Then make a plan. The owners who figure this out early will spend less and stress less than the ones who wait for the penalty notice.
