Title 24 reports for Temecula and Murrieta permits.

Temecula gives away five city-owned ADU plans and expedites them. Murrieta keeps a registry of private designers’ plans instead. In both, the energy model is the piece that never comes pre-approved.

The energy model never comes pre-approved

Temecula publishes its review times: 10–12 business days initially, 5–7 for resubmittals, footnoted that incomplete applications may delay them. Submittal is digital through Citizen Self Service, and CD-18 asks for two sets of calculations with the Certificate of Compliance and Mandatory Measures “completely filled out, signed by the proper individuals and printed on the plans.” Its Permit Ready ADU program hands over five plans and reviews them in 7–10 business days — and the 2BR/1BA plan is exactly 749 sf, one foot under the city’s own development-impact-fee question. The same handout says the T24.X sheets still need site-specific updates.

Murrieta publishes no plan-review turnaround at all — what it publishes is the queue in front of one: a completeness check of about 15 business days, and projects on state-mandated timelines must send a separate follow-up email or risk extended timelines. Its pre-approved ADU program is a registry of private designers’ sets, capped at four options apiece. DS-138 warns that any omitted item makes a submittal incomplete, and wants the compliance forms copied onto the full-size plan sheets. Both cities sit in Climate Zone 10, and neither appears on the CEC’s approved local-ordinance list for the 2025 Energy Code — no local energy reach code in either. An addition and a correction resubmittal face the same intake rules.

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.

Nearby, same flat rate: Vista & San Marcos, Oceanside, Moreno Valley and Escondido.

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

Temecula & Murrieta plan-check questions

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

What review times do Temecula and Murrieta publish?
Temecula publishes 10–12 business days for an initial submittal and 5–7 for resubmittals, footnoted that incomplete applications may delay review. Murrieta publishes none. What it does publish is a permit-processing completeness check of about 15 business days that sits ahead of plan review, plus a request to email the city separately on projects with state-mandated timelines.
Do Temecula’s Permit Ready ADU plans come with the Title 24 report?
No. The plans are free, though the city notes there are fees for submitting and building one. Its own handout says the energy calculations will need to be updated with site-specific calculations and the T24.X sheets updated. Murrieta’s program works differently again — a registry of private designers’ plans, limited to four options per set.
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.

How fast do I get it back?

24 to 48 hours on your first job, three business days for everything after that — a date you can put on the schedule, not an estimate. If your permit deadline is tighter than that, say so in the notes; I’ll tell you honestly whether I can hit it before you commit.

Send your Temecula or Murrieta plans.

Say which city in the notes — the CF1R comes back with the compliance forms formatted to print onto the full-size plan sheets, which is what both cities ask for.
