Title 24 reports for Whittier permits.
Whittier publishes a real number on its preapproved ADU track — roughly five business days for plan check — and still leaves the Title 24 report on the applicant’s own document list.
The plan set is frozen. The energy report isn’t.
Whittier keeps plan check in-house, and Planning goes first: the city states that before plans go in for Building & Safety review, projects “must first be evaluated by the Community Development’s Planning Services Division.” Its preapproved ADU program is where real numbers get published — a completeness check in 1–2 business days, plan check in approximately 5 business days, resubmittals in about 5 days — across four one-story detached plans at 311, 495, 757 and 800 sf. The city is blunt that those plans “cannot be modified in anyway.” One document is still yours to bring: “Building Energy Analysis Report (Title 24 Compliance)” sits on the applicant’s Step 3 list.
That is deliberate. The site-plan checklist asks for the “Location of proposed heating / cooling equipment per energy documentation,” so the plans get read against the energy report at intake. The city also names a form for small work: a water heater replacement needs a completed CF-1R-ALT, worth knowing before you quote a change-out. Solar PV under Energy Code Section 150.1(c)14 may still be required on top of a preapproved plan (more on ADU solar). Whittier is climate zone 9 and adopted the 2025 Energy Code on January 1, 2026; no local energy reach code beyond the state code was found on the city’s pages.
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.
Prices
Flat fees, in writing before I start. No hourly, no bid package, no change-order games — the number on the quote is the number on the invoice.
Your first report with me
One per client, homes under 3,000 square feet. Full energy model, CF1R and CHEERS registration. It’s a test run — send one job and see how it goes.
Every model after the first
The standard rate once you’re a client — the second building, ADU plus main house, the next project that walks in. Back in 3 business days.
Over 3,000 square feet
Quoted from the plans before any work starts, same day.
24×36 plan-sheet set
Your CF1R laid out full size, matched to your drawing set. Comes back as a PDF you drop straight in.
Revisions
Two revisions included, plus questions any time. Past two I quote first, before I touch it.
Commercial / tenant improvement
Send the plans and you’ll have a flat quote back the same day. No deposit, no minimum.
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.
Whittier plan-check questions
If yours isn’t here, see the full FAQ or call and ask.
How long does Whittier take to plan-check a preapproved ADU?
If the preapproved plan is fixed, why do I still need a Title 24 report?
Does my ADU or addition actually need one?
Almost certainly. New conditioned floor area — ADUs, JADUs, garage conversions, additions — triggers Title 24. So do alterations that touch the envelope, the ductwork, or the HVAC equipment, including a straight change-out. A remodel that only moves non-structural interior partitions usually doesn’t.
Send it either way. If it doesn’t need a report I’ll say so and there’s no charge for the look.
What do you need from me to start?
A PDF of the architecturals and the project address. Floor plans, elevations and a window schedule is plenty.
You don’t need the HVAC or water heater picked. If the plans don’t call them out, I model what I’d normally specify for that job — and I list every assumption in the email so nothing is buried. Swap any of it and I rerun; that doesn’t count against your free revisions.
The design doesn’t have to be finished either. Early is often better, because that’s when a compliance problem is still cheap to fix.
