Title 24 reports for Ventura permits.

Ventura issues fifteen residential permit types in minutes with no plan review at all, and eight of them are Title 24 alterations — which moves the moment somebody checks your energy paperwork from a plan checker’s desk to the field inspection.

Local plan check

Fifteen instant permits, eight of them energy work

Ventura issues fifteen residential permit types instantly through Symbium with no plan check, and eight are Title 24 alterations — window replacement, reroof, water heater, wall heater, HVAC replacement, a service panel upgrade to 400 amps, rooftop PV no larger than 38.4 kW and an energy storage system. The city’s words: issued in real time, in a matter of minutes. They are residential-only, and GIS-based historical property screening pulls designated properties off the window and reroof types. The one-page application behind them, BS 517 (Rev. 5-2023), prints “Title 24 Form Required” four times across five appliances, and window form BS 305 makes you write a U-factor and SHGC of 0.30 / 0.23 into a table, opening by opening.

So the review moves to the inspector. An HVAC change-out gets one visit — after a passing HERS inspection by a certified rater, with a copy of the certificate available at the time of inspection, which makes HERS registration the gate instead of plan check. The window checklist is the same idea in reverse: the factory stickers must still be in place at final. Ventura is Climate Zone 6 across 93001 through 93007. There is no local amendment to the Energy Code — SBMC 12.135.010 adopts the 2025 edition and the chapter contains no changes — and Ventura is on neither CEC approved-ordinance list, while Ojai is on both, its threshold dropping from 1,000 sf to 300 sf under the 2025 code. For drawn work — an addition, a new detached ADU — the city publishes no plan-check turnaround.

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

Ventura plan-check questions

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

Which Ventura permits skip plan check entirely?
Fifteen residential types issue instantly through Symbium, in the city’s phrase, in a matter of minutes — and eight of them are energy work: window replacement, reroof, water heater, wall heater, HVAC replacement, a service panel upgrade up to 400 amps, rooftop PV up to 38.4 kW and an energy storage system. Commercial buildings, duplexes, mobile homes and multifamily are excluded, and GIS screening removes historically designated properties from the window and reroof types.
If the permit is instant, when does anyone look at the energy documents?
At the inspection. Ventura’s HVAC checklist says a residential replacement can generally be inspected in one visit after a passing HERS inspection has been performed by a certified HERS rater, with a copy of the certificate available at the time of inspection. The window checklist runs the same way — the factory labels must be left in place on all windows and sliding doors to be verified at time of inspection.
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 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.

Instant permit or drawn set, the CF1R comes back registered so the HERS certificate is on file before the inspector asks for it at final.
