Title 24 reports for Simi Valley permits.

Simi Valley publishes its clock in three segments and says outright that plan check takes 20 to 25 working days and is the same for resubmittals — so a correction round costs a second full review, not a short recheck.

Local plan check

A resubmittal is a full second plan check

Building & Safety here sits in Environmental Services, not Community Development, and publishes its timeline in three segments: counter review may take up to 5 to 10 business days; then plan check takes 20 to 25 working days, and is the same for resubmittals; then up to 3 business days to issue the permit. Small permits carry their own numbers: a reroof 2 to 3 days, and a residential mechanical permit covering HVAC, FAU, AC, ductwork, coil and condenser the same — which makes an HVAC change-out among the quickest permits here. Because a correction round restarts the whole 20 to 25, the cheapest submittal is the complete one.

There is a packaging rule to match. Items go in as separate PDF files, but the plan set — site, architectural, structural, mechanical, plumbing, electrical and the Title 24 compliance forms — must be submitted as one PDF file and not as separate PDF files. Structural calculations stay outside it. State Energy Conservation Information is a listed drawing requirement on new homes and room additions, on commercial work and tenant improvements; the ADU checklist reduces the submittal to three items, the third Title 24 energy calculations. Simi Valley is Climate Zone 9 citywide, which the city never states: it publishes Seismic Design Category D or E and a 110 mph wind speed, and its Energy Code page still links the 2019 manuals. There is no local amendment to the Energy Code either — SVMC ch. 8-15 contains one section, Adoption — and the city is on neither CEC list.

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

Simi Valley plan-check questions

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

How does Simi Valley want the CF1R packaged?
Inside the plan set. The city asks for items as separate PDF files, but the site, architectural, structural, mechanical, plumbing and electrical sheets together with the Title 24 compliance forms must be submitted as one PDF file and not as separate PDF files. Structural calculations and reports stay outside that file. State Energy Conservation Information is a listed drawing requirement on residential, commercial and tenant-improvement submittals alike.
Which climate zone does a Simi Valley model run in?
Zone 9, for both delivery ZIPs, 93063 and 93065 — but the city never says so. Building and Safety publishes a Seismic Design Category of D or E, a 110 mph basic wind speed and exposure category B, and no building climate zone at all, while its own California Energy Code page still links the 2019 residential and non-residential manuals. The zone comes from the parcel, not the page.
Plan check came back with an energy comment. Now what?

Forward it to me. If it’s a job I did, the first two revisions are free and I answer the comment directly — you don’t have to translate between your plan checker and me.

If someone else did the original report, I’ll still take it. Send the comment and the existing CF1R and you’ll get a flat quote back the same day.

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.

Send your Simi Valley plans.

The CF1R comes back as sheets that merge straight into the single plan-set PDF the city asks for, so nothing bounces at counter review and nobody spends 20 to 25 days twice.
