How can we help?

It's a home-improvement project manager: a step-by-step plan, materials and shopping list, budget, tool shed, and permit help that checks your town's published rules first. Sully, the app's AI guide, walks you through it.

Sully is designed for any U.S. town, using a town, county, state, model code ladder. Results depend on what your town publishes. When a rule can't be found, the report says so and tells you who to call.

No. Your local permit office issues permits and decides. Sully gives general guidance, not legal or engineering advice.

Tap “this looks wrong” on the rule, and confirm it with your permit office. If you'd like us to look too, email us the project type and town.

With Hire a pro, you choose whether to connect and see what's shared first. If we add pro-matching partners in the future, we may earn a fee when you connect with a pro through them. We'll disclose it right there.

Open the project and start denial recovery. Take a photo of the letter or paste its text, and Sully explains each reason, the fix and the next steps. It's included with a Sully Stamp for that project, or with Sully Pro.

Yes. The filing packet is a PDF you can save, print or email from the app.
