Build it right.
Permit or not.

Sully never answers with “call the permit office.” You get the code section, what it means for your project, and what to do next.

How it works

From “can I build this?”
to a permit-ready plan.

  1. 01

    Tell Sully the idea

    Chat in plain English, or start from a napkin sketch. Sully asks only what it needs.

  2. 02

    Fill a short project form

    A form built for your project type: size, height, attachment, location. Seconds, not pages.

  3. 03

    Get a real answer

    Short and specific, with code citations for your jurisdiction. Then open project mode for drawings and site photos.

  4. 04

    Review, then Stamp

    The readiness review scores you toward 100 and names each blocker. Clear them and get your Sully Stamp.

Napkin sketch

Draw it badly.
Sully cleans it up.

Photograph the rough sketch on the back of an envelope. Sully reads your dimensions, works out the house, the setbacks and the property line, and turns it into a clean plan you can mark up in project mode.

The Sully Stamp

The report you carry to the counter.

When your readiness review reaches 100, Sully writes it up as one tidy report: the project, the authority that issues your permit, the code edition it adopted, and every key requirement with its citation.

Straight answers.

Does Sully work where I live?

Yes. Sully covers all 50 states. It works out the authority that issues permits at your address and the code edition it has adopted, and answers from there.

Is the Sully Stamp a permit?

No. Your local building department issues permits. The Sully Stamp is a readiness report that organizes what the office will ask for, with code citations, so your application is complete.

Will Sully just tell me to call the city?

No. Sully gives a real answer: whether you likely need a permit, which code sections apply, and what to do next. If something truly depends on a local decision, Sully says exactly what to ask.

Do I need an account to try it?

No account is needed to ask Sully a question. Sign in with Apple or Google to save projects across devices.
