NYC No. 4 Heating Oil Phase-Out Under Local Law 32

New York City prohibits most boilers from burning No. 4 heating oil starting July 1, 2027. If your building still uses No. 4 oil, check when your boiler authorization expires and plan the conversion before the applicable deadline. Energo helps building owners and property managers across all five boroughs assess equipment and plan fuel conversions.

When Does NYC’s No. 4 Heating Oil Ban Take Effect?

For most privately owned buildings, the cutoff is July 1, 2027. The ban already applies to boilers in City properties and Department of Education public schools as of July 1, 2025. Certain electricity and steam generation facilities had an earlier January 1, 2025 deadline.

NYC stopped issuing and renewing work permits, certificates of operation, and registrations for boilers to burn No. 4 oil on June 30, 2024. If your current authorization expires before the citywide cutoff, plan around that earlier date. The city lists penalties of up to $10,000 for noncompliance. See NYC Accelerator’s building energy law guidance.

What Are Your Options for Converting From No. 4 Oil?

Switch to No. 2 Heating Oil

If your system is compatible, switching to No. 2 heating oil may allow you to keep some existing equipment. Your boiler, burner, tank, and fuel lines should be evaluated first. Depending on the equipment and work involved, the conversion may require burner adjustments, fuel-system cleaning, testing, a Department of Buildings (DOB) permit, or updates to Department of Environmental Protection (DEP) records.

Evaluate Natural Gas or Dual-Fuel

Natural gas or a dual-fuel system may be an option if your building can obtain the required utility service and the project meets applicable codes. The equipment, permits, and utility approvals involved can affect both cost and timing. Energo can help assess the scope alongside your Local Law 97 emissions compliance plan if your building is covered.

Frequently Asked Questions About Local Law 32

When is No. 4 heating oil banned in NYC?

Most NYC boilers must stop burning No. 4 heating oil by July 1, 2027. The restriction took effect earlier for boilers in City properties, Department of Education public schools, and certain electricity or steam generation facilities.

Can I keep burning No. 4 oil until July 2027 if my boiler permit expires first?

An existing authorization does not give you until July 2027 if it expires sooner. Since June 30, 2024, NYC has prohibited issuing or renewing work permits, certificates of operation, or registrations for boilers to burn No. 4 fuel oil. Check your equipment records and expiration dates before planning your conversion.

Can my existing boiler switch from No. 4 oil to No. 2 oil?

It depends on the condition and compatibility of your boiler, burner, tank, and fuel lines. Some systems can be adapted. Others need equipment upgrades or replacement. An on-site assessment can identify what can stay and which permits or filings apply.

Does Local Law 32 require my building to switch to natural gas?

No. Local Law 32 prohibits burning No. 4 fuel oil in boilers. Compatible systems may be able to switch to No. 2 heating oil. Natural gas or dual-fuel may be an option where utility service and applicable codes allow it.

Does Local Law 32 allow an extension to keep burning No. 4 oil until 2030?

No. A provision in the law allows eligible owners to request more time for certain additional construction code work triggered by the conversion, subject to NYC DOB approval. It does not extend the deadline to stop burning No. 4 oil.

Does converting from No. 4 oil satisfy Local Law 97?

Local Law 32 governs the fuel your boiler can burn. Local Law 97 has separate emissions limits and reporting requirements for covered buildings. A fuel conversion can affect your emissions, so review its impact against your building’s own Local Law 97 limit.

What should I have ready for a No. 4 oil conversion assessment?

Start with your building address, current fuel grade, boiler and burner information, and any DEP registration or certificate of operation you have. If you do not know which fuel you use, check a recent delivery invoice or ask your supplier.
