How to Qualify for the 5% FAR Bonus in NYC New Construction
New York City's ULEB program offers developers and property owners up to 5% additional Floor Area Ratio — free buildable area — for new construction projects that meet specific energy performance standards. Here's exactly how to earn it.
Is Your Project Eligible?
Before investing in design changes or energy modeling, confirm your project meets the basic eligibility criteria:
- Project type: New construction or a qualifying building enlargement. Renovations and change-of-use projects do not qualify.
- Zoning district: The ULEB bonus applies across most NYC zoning districts. Confirm with your architect or zoning attorney that your specific district is covered.
- Filing date: Projects filed under the current NYC Energy Conservation Code are subject to ULEB requirements. Projects with earlier filings may be subject to different rules.
If your project is new construction in NYC and you have not yet filed your energy compliance documents with the DOB, you can pursue the ULEB bonus. Contact us for a no-cost eligibility review.
The Value Calculation
Before committing to the ULEB path, understand what the 5% bonus is actually worth on your project. The math is straightforward:
Example: 10,000 SF lot in Brooklyn
The incremental cost of achieving the 15% energy performance threshold — primarily through a stronger building envelope and efficient mechanical systems — typically ranges from $200,000 to $800,000 on a project of this size. The return on that investment is often 3x to 10x.
The 5-Step Qualification Process
Commit to Full Electrification
The ULEB bonus requires compliance with Local Law 154 of 2021, which prohibits fossil fuel combustion systems in new construction. This means your building must use all-electric heating, cooling, domestic hot water, and cooking — no gas service of any kind in most project types.
This decision affects your mechanical system design, utility connections, and equipment specifications. Make it early, before schematic design is complete, so your engineering team can design around it from the start rather than retrofitting it later.
Engage a ULEB Energy Modeler
Hire a qualified energy modeler experienced in ULEB submissions before your design team finalizes envelope and mechanical systems. The modeler will run preliminary energy simulations to identify which design strategies — insulation levels, glazing ratios, HVAC efficiency, lighting power density — will achieve the 15% performance threshold most cost-effectively.
Early engagement allows the modeler to guide design decisions rather than simply document them. This distinction matters: a model run at design development may reveal that switching from a VRF system to a WSHP system saves $50,000 in construction cost while improving energy performance. A model run at permit application can only document what's already designed.
Finalize and Document the Energy Model
Once the design is sufficiently developed, your energy modeler will run the formal ULEB energy model — a whole-building simulation using DOE2-based or equivalent approved software — and prepare the required documentation package. This includes:
- A comprehensive energy modeling report with input assumptions and output results
- The DOB EN1 form (or equivalent ULEB-specific form)
- Verification that the modeled systems match the construction documents
- Electrification compliance documentation under Local Law 154
The energy model must clearly demonstrate that the proposed building achieves at least 15% better energy performance than the NYCECC baseline for a building of the same type and location, including both regulated and non-regulated end-uses.
Submit to the NYC Department of Buildings
Your architect of record files the ULEB energy model documentation with the NYC DOB as part of the construction document submission. The DOB reviews the energy model for compliance with NYCECC requirements and ULEB performance thresholds.
DOB objections are common — the review process may identify missing information, modeling assumptions that require clarification, or documentation gaps. A ULEB modeler experienced with DOB review can anticipate these objections and prepare responses efficiently. Working with a modeler who handles objections through approval as part of their service is strongly recommended.
Complete Verification and Receive CO
The ULEB program requires post-construction verification. After construction is complete, a registered design professional must conduct inspections, commissioning, and airtightness testing to verify that the completed building meets the ULEB performance standards specified in the energy model.
A final verification report must be submitted to the DOB before a certificate of occupancy is issued. No CO is granted without this sign-off. This step is non-negotiable — ensure your construction contract and project schedule account for it.
Common Reasons Projects Fail to Qualify
After reviewing dozens of ULEB submissions, the most common reasons projects fail to earn the bonus are:
- Late engagement of the energy modeler. When modeling is treated as a permitting deliverable rather than a design tool, teams often discover the 15% threshold requires expensive late-stage design changes.
- Gas retained for cooking or backup. Any fossil fuel combustion system disqualifies the project under Local Law 154, even if it's limited to a single appliance.
- Modeling scope errors. Using a residential modeling scope for a mixed-use building, or omitting required non-regulated end-uses, can cause a technically sound design to fail on paper.
- Construction deviations. Systems installed during construction that differ from the approved energy model — even minor substitutions — can trigger DOB objections at the CO stage. Track all system changes against the approved model throughout construction.
ULEB Documentation Checklist
Use this checklist to ensure your submission package is complete before filing with the DOB:
- Whole-building energy model demonstrating ≥15% performance above NYCECC baseline
- DOB EN1 form (or current equivalent) completed and signed by a registered design professional
- Local Law 154 electrification compliance documentation
- Construction documents with all energy-related features clearly identified and consistent with the energy model
- Electronic modeling input and output files available for DOB review upon request
- Post-construction inspection, commissioning, and airtightness testing plan
Timeline Expectations
A realistic ULEB process from first engagement to DOB approval typically takes 6 to 14 weeks, depending on project complexity and the completeness of construction documents at the time of engagement. Post-construction verification typically takes 4 to 8 weeks after construction completion, depending on the size of the building and the scope of required commissioning.
Budget for ULEB as a line item in your project pro forma. A dedicated ULEB energy modeler typically charges $8,000 to $25,000 for the full service depending on building size and complexity — a small fraction of the value the FAR bonus delivers.
