New York City’s first year of building-emissions reporting has produced high participation, but enforcement is underway for properties that have not met their obligations. Meanwhile, Denver has introduced a review process with a December 31 deadline for owners challenging certain earlier building-performance decisions, according to the cities’ Local Law 97 announcement and Energize Denver program guidance.
For property managers, the developments highlight a distinction that can get lost in a compliance spreadsheet: submitting a report, meeting a performance target and receiving approval for an alternative path are different milestones.
New York’s results show why the compliance pathway matters
New York’s initial results cover building operations during 2024, the first compliance year under Local Law 97.
Among properties reporting under Article 320, which generally requires annual reporting against building-specific greenhouse gas emissions limits, approximately 95% met their 2024 limits. The Department of Buildings audited every Article 320 report, according to Urban Green Council’s September analysis of the city’s results.
That percentage does not mean 95% of every building covered by Local Law 97 satisfied an identical requirement. The law includes different compliance pathways. Properties and buildings are also different counting units, a distinction reflected in the city’s April compliance announcement.
Article 321, available to certain affordable housing properties and houses of worship, allows qualifying properties to comply through prescribed energy-saving improvements rather than an annual emissions cap. Urban Green Council reported that approximately 95% of Article 321 properties had either completed their requirements or requested mitigation.
Those outcomes should not be combined into a single “work completed” category. A mitigation request does not establish that a property has finished its improvements or received approval.
For managers overseeing mixed portfolios, the practical implication is straightforward: identify each property’s applicable pathway before assigning its compliance status.
Enforcement follows missing reports and unresolved obligations
New York has paired enforcement with opportunities to correct deficiencies.
In its April 22 announcement, the Department of Buildings said it had begun issuing Notices of Deficiency to properties that had not reported. The notices provided another 60 days to submit late reports and potentially avoid penalties.
The department also said it was preparing cases for the Office of Administrative Trials and Hearings involving properties that remained out of compliance.
By September, some properties referred for penalty assessment were submitting their missing reports. Almost a third of properties exceeding their emissions limits had received good-faith-effort mediated resolutions that allowed time to complete energy-saving retrofits, according to Urban Green Council.
These are materially different positions. A property may have submitted its report but exceeded its limit. Another may have received additional time for work but still need to satisfy the terms of its resolution.
A filing receipt, an approved work plan and confirmation of completed improvements document different stages of compliance.
Denver creates a year-end review opportunity
Denver’s Energize Denver program presents a separate, time-sensitive development.
Rules adopted in August 2026 introduced a pre-compliance decision review process. Owners can request review of certain city decisions involving an application or submission, including a denied alternative compliance option or an allegedly incorrect target adjustment, according to the city’s program guidance.
Normally, an owner must request review within 30 calendar days of the initial decision notice. For decisions dated before August 27, 2026, however, Denver allows requests through December 31, 2026.
The city says a request must describe the decision, explain the alleged error, identify the desired outcome and include supporting exhibits. The original application or submission must also have met minimum requirements to qualify for further review.
For managers handling regulatory correspondence, the immediate task is to determine whether ownership received an eligible decision that warrants review. That means locating the original submission, the city’s notice and the building records supporting the requested correction.
The December deadline is not a general extension of Energize Denver obligations. It is a review window for specified earlier decisions.
Performance requirements do not prescribe the same project for every building
Energize Denver applies to commercial and multifamily buildings of at least 5,000 square feet, with different requirements for buildings from 5,000 to 24,999 square feet and those of at least 25,000 square feet.
The city explicitly states that its policy is not a blanket requirement to electrify heating or cooling. It also says the program does not require owners to replace HVAC equipment before the end of its useful life or impose the same energy-reduction requirement on every building.
That distinction matters when managers present capital requests. The applicable target and available compliance options should be established before a particular equipment replacement is described as legally required.
New York’s framework is different. Local Law 97 generally covers buildings larger than 25,000 gross square feet, with requirements and pathways that vary by property. Its emissions limits become more stringent in 2030, according to the city’s explanation of the law.
A successful first-year result therefore does not establish that a building is ready for the next compliance period.
What managers should put in front of ownership
The operating challenge is connecting regulatory records with maintenance schedules and capital plans.
A useful internal status report should answer four questions:
- Which requirement and compliance pathway apply to the property?
- Has the required filing been submitted, and has the agency identified any deficiencies?
- What work, approval or supporting documentation remains outstanding?
- Who owns the next action, and when is it due?
These are management recommendations, not additional legal requirements. Their purpose is to prevent an administrative milestone from obscuring an unresolved performance obligation.
New York’s tighter 2030 limits call for forward planning. Denver’s December review deadline calls for an immediate check of earlier decisions. In both cases, the manager’s role is to show ownership what has been filed, what has been accepted and what still requires action.
