Get your ADU permit faster
Use our free online mapping tool to mark up your property and generate a site summary with key site information.
Then, turn it into a permit-ready site plan using your city’s pre-approved ADU designs.
You’ve heard it’s easy to build a pre-approved ADU — yet no one tells you where to start.
Cities offer pre-approved ADU plans — but the planning department still requires a custom site plan for your property.
It’s confusing and complicated when you are doing it for the first time.
Our Site Plan Tool makes it easy — simply follow the prompts to map your utilities, trees, driveways and structures.
How it works
From backyard sketch to permit approval - in two steps.
Map your property
Our free online tool helps you quickly outline your property and key features the city needs to see.
You’ll get an instant site summary.

Our team turns your site data into a professional plan that meets city requirements.
No back-and-forth, no guesswork.

The one document your city won’t approve an ADU without.
A site plan shows your entire property — distances between structures, where the new ADU goes, how to access it, and how it connects to existing utilities.
Cities use site plans to confirm that your ADU meets zoning and safety rules — things like setbacks, access, and utility connections.
Without a clear, scaled site plan, your permit can’t move forward.
We create site plans that meet official California city standards — ready for submission with pre-approved ADU designs.
