A TR8 inspection in NYC is an energy code progress inspection filed under the Department of Buildings’ Technical Report 8, the form that identifies every energy-related check a project needs and certifies, once construction is done, that those checks were performed and passed.1New York City Department of Buildings. TR8 – Technical Report Statement of Responsibility for Energy Code Progress Inspections It applies to most new buildings and major alterations with heated or cooled space, and without a completed TR8 the Department will not issue a Certificate of Occupancy.2NYC Buildings.

What a TR8 Actually Covers
The TR8 sorts energy code compliance into three categories, and the specific checks required for your job depend on the scope of work and the compliance path chosen in Section 10 of the PW1 application.3NYC Buildings. DOB NOW Build – Special and Progress Inspector User Manual
Building Envelope
Envelope inspections look at the shell between conditioned and unconditioned space. Inspectors verify insulation placement and R-values, foundation insulation protection, fenestration and door U-factors, fenestration air leakage, window and door area calculations, and air barrier continuity.1New York City Department of Buildings. TR8 – Technical Report Statement of Responsibility for Energy Code Progress Inspections If a window arrives without a manufacturer’s label, the inspector has to obtain an independent NFRC-standard report certifying each unit type’s assembly values.4New York City Department of Buildings. TR-8 Inspections Reporting
Mechanical and Service Water Heating
This category takes in HVAC equipment, duct and pipe insulation, controls and thermostats, ventilation and air distribution layout, shutoff dampers, and duct leakage testing. Water heating equipment is verified against the efficiency ratings submitted at filing. The inspector reviews both the installation and the control sequences to confirm the systems will perform the way the energy analysis predicted.4New York City Department of Buildings. TR-8 Inspections Reporting
Electrical Power and Lighting
Lighting checks confirm that automated controls are installed and functioning. Occupancy sensors are required in a broad list of space types, from classrooms and conference rooms to open-plan offices, restrooms, storage rooms, and warehouses, and they must turn lighting off within 15 minutes of the last person leaving.5New York City Department of Buildings. How-to Guide – Supporting Documentation In Compliance with 2020 New York City Energy Conservation Code – Section: Lighting and Electrical Power Daylight-responsive controls are verified to confirm they reduce artificial lighting when natural light is sufficient, and exterior lighting is checked against allowable power density limits.
Timing: When the Inspector Has to Be There
This is where projects fall apart. Most TR8 inspections have to happen while the work is still exposed. Close up the wall and the chance to verify what’s inside is gone.
Insulation placement and R-values must be confirmed while walls, ceilings, and floors are open, before drywall or other finishes go on. Fenestration U-factors have to be confirmed before insulation and interior finishes cover the frames. Air barrier visual inspections run as interior work begins and cover fenestration sealing, pipe and outlet penetrations, rim joists, duct enclosures, and sealing between conditioned and unconditioned spaces. Ventilation and ductwork need documentation while cavities are still accessible.4New York City Department of Buildings. TR-8 Inspections Reporting
The contractor is required to notify the progress inspector before covering or concealing any portion of work that still needs inspection. Multiple visits are often necessary, and the inspector and contractor have to sequence them so nothing gets sealed prematurely.4New York City Department of Buildings.

Who Can Perform and Sign the TR8
The property owner hires an approved progress inspection agency. A registered design professional (a New York State licensed Professional Engineer or Registered Architect) has to serve as the primary inspector or inspection supervisor. For residential energy code work, that RDP needs at least five years of experience with energy code systems. For commercial buildings, the same five-year minimum applies, with at least three years in the specific system type being inspected.6NYC Buildings. 1 RCNY 101-07 – Approved Agencies
Supplemental inspectors who aren’t registered design professionals can also perform inspections, but only under the direct supervision of the inspection supervisor, and they need at least three years of relevant inspection or construction observation experience.6NYC Buildings. 1 RCNY 101-07 – Approved Agencies Only a registered design professional can actually sign the TR8 and the accompanying EN2 form.2NYC Buildings. Progress Inspections
The inspector cannot have any financial or other interest in the construction, installation, manufacture, or maintenance of what they are inspecting. The rule is wider than simply being a different person from the contractor; any relationship that could compromise objectivity disqualifies the inspector.6NYC Buildings. 1 RCNY 101-07 – Approved Agencies
The EN2 Form and As-Built Verification
The TR8 isn’t the only document closing out the energy side of the job. Before sign-off, the progress inspector also completes an EN2 form, which certifies that the values found in actual construction match those in the last-approved energy analysis.2NYC Buildings. Progress Inspections
If construction deviated from the approved plans, the original preparer of the energy analysis has to produce an as-built energy analysis using the values actually installed. That updated analysis still has to demonstrate compliance with the New York City Energy Conservation Code. The preparer signs and seals it, and the progress inspector then certifies on the EN2 form that the as-built analysis matches the site.2NYC Buildings. Progress Inspections If the as-built analysis fails to comply, the inspector cannot complete the EN2 and the application won’t be signed off. The only path forward is corrective work followed by another round of analysis and verification.
When Commissioning Is Also Required
For larger or more complex projects, the TR8 process includes a commissioning component. Whoever files the TR8 has to determine whether commissioning is required under Section C408 of the energy code or ASHRAE 90.1 Section 6.7.2.3. If it is, a preliminary commissioning report must be certified and provided before the TR8 can be signed off.1New York City Department of Buildings. TR8 – Technical Report Statement of Responsibility for Energy Code Progress Inspections Commissioning typically applies to mechanical, lighting, and envelope systems in commercial buildings above certain size thresholds. Overlooking it is a common reason projects stall at the finish line.
How the TR8 Is Filed in DOB NOW: Build
The TR8 is filed electronically through DOB NOW: Build. The form appears as part of the application only if NYCECC or ASHRAE was selected as the compliance path in Section 10 of the PW1.3NYC Buildings. DOB NOW Build – Special and Progress Inspector User Manual
Filing happens in two phases. Before construction begins, the progress inspector identifies every required inspection category for the scope of work and accepts responsibility for conducting those inspections. The inspector’s license type and number are linked to each requirement in the system. This step has to be complete for a permit to issue.3NYC Buildings. DOB NOW Build – Special and Progress Inspector User Manual
After all physical inspections are performed, the progress inspector logs back in to certify each requirement as complete, applying a professional seal and signature through the portal and acknowledging that false statements carry sanctions under NYC Administrative Code Section 28-211.1.2.1New York City Department of Buildings. TR8 – Technical Report Statement of Responsibility for Energy Code Progress Inspections Once all TR8 requirements and the EN2 are complete, the application can move toward a Certificate of Occupancy or Temporary Certificate of Occupancy.
The form itself requires the DOB job number (BIS job number), the property address and BIN, and identification of every progress inspection and commissioning requirement applicable to the project.1New York City Department of Buildings. TR8 – Technical Report Statement of Responsibility for Energy Code Progress Inspections The owner authorizes the filing, and the inspection agency’s principal or director accepts responsibility for conducting the identified inspections. The inspector also has to identify which energy code version applies, since the applicable code depends on the filing date.
When Something Doesn’t Match the Plans
If installed work doesn’t match the approved documents, the inspector reports the deviation with a description and photographs of both the discrepancy and the alternative construction. If the deviation presents a gross detriment to total building performance, the inspector submits the report immediately to alert the Department.4New York City Department of Buildings. TR-8 Inspections Reporting
The inspector also provides corrective recommendations describing the non-conformance and what has to happen before work can advance to the next phase.4New York City Department of Buildings. TR-8 Inspections Reporting Where insulation can’t be verified by its label, the inspector has to obtain a site-specific, dated installer’s certificate or other field evidence confirming the type and thickness installed. Generic manufacturer specification sheets don’t count.
What’s Exempt, and the 2026 Landmark Change
Not every job triggers a TR8. Application types not regulated by the NYCECC include full demolitions, sign applications (unless the sign affects the building envelope), emergency generators, and subdivisions.7NYC Department of Buildings. Energy Conservation Code
Buildings with state or national landmark status have historically been exempt from energy code compliance. Under the 2025 NYCECC, which takes effect March 30, 2026, historic buildings are no longer automatically exempt.7NYC Department of Buildings. Energy Conservation Code Narrower exceptions remain for city-designated landmarks and historic district properties, including storm windows over existing fenestration, glass-only replacements in existing sash and frame, and alterations to cavities where existing structures lack framing. The blanket exemption is gone, so many landmark projects filed after March 2026 will need TR8 inspections for the first time.
Penalties for Skipping or Falsifying
Energy code violations can be classified as immediately hazardous, major, or lesser. Immediately hazardous violations draw penalties of $2,500 to $25,000 per violation, plus up to $1,000 per day uncorrected. Major violations run $1,000 to $10,000, plus up to $250 per month. Lesser violations can bring fines up to $500 each.8American Legal Publishing Code Library. NYC Administrative Code 28-202.1 – Civil Penalties
If site conditions are deemed unsafe, the Department can issue a Stop Work Order halting construction. Violating a Stop Work Order brings a $6,000 penalty for a first offense and $12,000 for each subsequent offense, and the order stays in place until all penalties are paid and all cited conditions are corrected and re-inspected.9NYC Buildings. Stop Work Order
Filing a false TR8 carries separate consequences. Under NYC Administrative Code Section 28-211.1.2, anyone found to have knowingly or negligently made a false statement on a required form can be barred from having future applications or documents accepted by the Department.1New York City Department of Buildings.
