Terms of service
Short and specific. If anything here conflicts with the written quote for your job, the quote wins.
What you are hiring, and on what terms
Plain terms for a small, specific service: T24 Studio builds the energy model and produces the Title 24 compliance documentation for your project. Using this site or sending a plan set means these terms apply. If anything here conflicts with the written quote for your job, the written quote wins — it is the document with your actual scope and price on it.
What T24 Studio is, and is not
This is stated on the home page and it is worth repeating here because it is the term that matters most. T24 Studio is the documentation author on your compliance certificate, not the responsible designer. I am not a licensed engineer or architect, I do not stamp drawings, and I do not perform HERS or ECC field verification — that is a separate trade the owner or contractor hires. You remain the responsible designer of record and the registered certificate names you as such. Nothing about your role, your license, or your liability on the project changes by hiring me for this piece of it.
Quotes and price
Prices are flat and quoted in writing before any work starts, and the number on the quote is the number on the invoice. The rate card on the home page is the price for residential work under 3,000 square feet; anything larger, or commercial and tenant-improvement work, is quoted from the plans. Rates shown on this site are current pricing and can change for future jobs — a quote you have already been given does not change.
What I need from you
A plan set and a project address. The model is only as good as what it is built from, so you are responsible for the accuracy of what you send — dimensions, orientation, assemblies, equipment. Where the plans do not specify mechanical or water-heating equipment, I model what I would normally specify for that job and list every assumption in writing. Correcting the model after you change one of those assumptions is a rerun, not a revision, and is not charged as one.
Revisions and plan check
Two revisions are included on a report I produced, including answering an energy-code comment from plan check. Past two, you get a quote before anything is touched. A revision needed because the design changed is still a revision; a rerun caused by an assumption I made is not.
What is not promised
The work is done to comply with the applicable Title 24 code cycle as I read it, using the state’s own compliance software. No one can promise a building department will approve a permit — plan check is a human process, local jurisdictions apply reach codes and local amendments, and reviewers disagree. What is promised is that if an energy comment comes back on my report, I answer it, and the first two of those are free.
Payment
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.
Registration
California requires the compliance certificate to be registered with an approved data registry before a building department will accept it. I use CHEERS and registration is included in the rate. The registry is a third party operating under its own rules and its own terms; its availability and processing are not something I control.
Who owns what
Your plan sets stay yours. The compliance documents produced for your project are yours to use on that project once paid. The underlying energy model, working files and this website’s content remain T24 Studio’s. Reselling or redistributing a report as a compliance product for a different project is the one thing not covered.
Limits
Liability for a job is limited to what you paid for that job. Consequential losses — schedule delay, carrying costs, lost profit — are not covered. To be clear about the boundary, this does not limit liability for the work actually performed, and it does not limit anything California law does not permit to be limited.
Governing law
These terms are governed by the laws of the State of California, and any dispute belongs in the state or federal courts serving Riverside County, California.
Changes and contact
If this page changes, the date below changes with it, and the version in effect for your job is the one at the time of your quote. Questions: info@t24studio.com or (951) 733-9108.

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.
Terms questions
If yours isn’t here, email and ask.
Does hiring you change my role on the project?
Can you guarantee the permit gets approved?
What happens if the design changes after I get the report?
