How much does a Title 24 report cost?

Flat fee, quoted before anything starts — $99 for your first report, homes under 3,000 square feet. No hourly billing, no line-item surprises on the invoice.

The short answer

One flat number, not a range

A lot of Title 24 pricing online is quoted as a range — “$200–$500” — because it depends on hourly rates, revision fees, or a bid that changes once the scope is understood. T24 Studio prices flat instead: $99 for a new client’s first report (struck from $150), $150 flat per model after that, both for homes under 3,000 square feet. The number on the quote is the number on the invoice.

What moves the price isn’t the city, the code cycle, or how complicated the HVAC is — it’s square footage and building type. Over 3,000 square feet, or commercial and tenant-improvement work, gets a flat quote back the same day once the plans are in hand, because scope varies too much there to price sight-unseen. An ADU or garage conversion under 3,000 square feet runs the same rate card as anything else residential — there’s no separate “ADU markup.”

Process

How it works

  1. 01

    Send the plans

    A PDF of the architecturals and the project address. If something’s missing I ask once, in one email — not five.

    Mechanical and plumbing don’t have to be picked yet. If the plans don’t call out the HVAC or the water heater, I model what I’d normally specify for that job and tell you exactly what I assumed. Change any of it and I’ll rerun — that’s not a revision.

  2. 02

    I build the model

    If the design does not comply as drawn, I tell you what the model needs to pass and the least disruptive way I can find to get there — your call what goes on the drawings.

  3. 03

    You get it back ready to sign

    CF1R registered with CHEERS, you named as the responsible designer. 3 business days — 24–48 hours on your first one. Pay on delivery: Zelle, Venmo or Cash App.

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

Pricing questions

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

How does payment work?

Flat fee, quoted in writing before I start — the number on the quote is the number on the invoice. You pay on delivery, not up front: Zelle, Venmo or Cash App. No deposit, no retainer, no minimum, and nothing to sign to keep sending work.

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.

Does the price change if plan check sends back a comment?
No, not on a T24 Studio report — the first two revisions are free, including answering an energy-code plan-check comment. Past two, you get a quote before anything is touched. See plan-check corrections for how that works if the original report wasn’t written here.
Why do other Title 24 quotes vary so much?
Most of the spread comes from how the work is billed — hourly, or a bid that gets revised once the reviewer sees the plans — plus how revisions and registration fees are handled. A flat rate quoted up front removes that variability; it’s the same $99 first-job / $150-after structure regardless of what the model turns out to need.
