Title 24 reports for San Francisco permits.

The energy paperwork here has its own inspection unit, its own email address and its own final affidavit — and the Certificate of Final Completion and Occupancy does not issue until every Title 24 item is cleared.

Local plan check

The energy paperwork has its own inspector

The Department of Building Inspection publishes four information sheets whose only subject is Title 24 energy documentation, split by building type and all dated August 6, 2026 — M-03 covers single-family, M-06 the process. M-03 says the responsible designer fills in the CEC and Green Building Code inspection checklists and affixes them to the drawings before permit approval. Each item then becomes a form code in DBI’s Permit Tracking System. Before final, a certified ECC rater emails a compliance affidavit to DBI’s Energy Inspection Services unit, and the sheet says the permit will not be finalized without it. The carve-out: alterations where field verification is not required, such as water heater and window replacements, and additions under 300 square feet.

The whole city and county is Climate Zone 3. There is no local amendment to the Energy Code — the city publishes its own 2025 Building, Green Building, Mechanical and Plumbing codes but no San Francisco Energy Code, and sits on neither CEC approved-local-ordinance list; the electrification rules live in Building Code § 106A.1.17 and the Green Building Code. GS5, the form every residential applicant signs, carries them: freestanding ADUs must be all-electric, and for permits filed July 1, 2026 or later so must Major Renovations, a term defined at Building Code § 202. On the 2025 codes the city is blunt — there is no grace period.

One thing that doesn’t change by city: my price and turnaround are flat statewide — $99 first report, $150 flat after, 24–48 hours on your first job. What differs city to city is what happens on the plan-check side before and after the CF1R lands in your permit set, which is what this page covers.

Disclosure

One honest note

I’m not a licensed engineer or architect, and I don’t stamp drawings. On the CF1R I’m the documentation author — you stay the responsible designer. Nothing about your role on the job changes.

That’s on purpose. I’m not after your scope or your clients. I do one piece of the permit set — the piece that usually holds it up — and I do it fast.

Questions

San Francisco plan-check questions

If yours isn’t here, see the full FAQ or call and ask.

Who signs off the energy work before a San Francisco permit closes?
DBI runs a dedicated Energy Inspection Services unit at 49 South Van Ness Avenue, Suite 400. Before final, a compliance affidavit goes to that unit — for ECC items it must come from a certified ECC rater, and for NRCA-MCH and NRCA-LTI/LTO acceptance tests from a certified ATT. Information Sheet M-06 adds that the Certificate of Final Completion and Occupancy will not issue until all required Title 24 items are cleared.
Does San Francisco publish a plan-check turnaround?
One number, and it is narrow. DBI aims to provide comments or approve permit applications for new residential buildings of one to ten units with no floors above 40 feet within 30 business days of receiving payment of the filing fees. Nothing is published for additions, alterations, ADUs or commercial work. Over-the-counter review is budgeted by time instead — projects needing less than one hour of plan review.
Does the project need HERS field verification?

Sometimes — typically for duct leakage, refrigerant charge, or certain heat-pump and quality-insulation measures. The CF1R lists exactly which measures need it, and I’ll flag it in the email so it isn’t a surprise at inspection. The field testing itself is done by a third-party HERS rater the owner or contractor hires; that’s outside what I do.

What is CHEERS registration, and is it extra?

California requires the compliance certificate to be registered with an approved data registry before the building department will accept it. I use CHEERS, and registration is included in the rate — no separate registry fee, no account you have to open.

The CF1R comes back ready to sit on the drawings next to the CEC and Green Building Code inspection checklists, which is what DBI wants affixed before the permit is approved.
