Visit mayberryworkshop.comWhat our permit labels mean
The drawings are complete and ready to submit. Your city reviews your project through its standard permit process.
We have submitted this plan to the city named on the label for pre-approval. The city has not approved it yet.
The city named on the label has reviewed and pre-approved this plan. Your project still needs a site plan and a permit for your lot, and changes to the plan can move it to standard review.
City labels apply only to the plan and city shown. A plan with no label for your city goes through that city's standard permit process. Timing, fees and eligibility vary by city and lot, and we confirm your path at the site evaluation.
How it works
Check your lot
Most single-family lots support at least one ADU. Start with the lot search.
Configure
Choose a plan, roof and exterior materials, and an interior vibe.
Site evaluation
We walk your site, confirm your price and turn your selections into a contract.
Permit and build
Permits take a few weeks to 3 months depending on the city. Construction takes about 5 to 6 months.

Common questions
What does an ADU cost to build?
We confirm price after a site evaluation, because tree removal, landscape patching and utility hookups vary from lot to lot. The configurator gives you an all-in starting number.
How long do permits take?
From a few weeks to about 3 months, depending on the city. Construction takes about 5 to 6 months after that.
What does permit ready mean?
Permit ready means our drawings are complete and ready to submit to your city, which reviews your project through its standard permit process. Pre-permitted means a city has already reviewed and pre-approved a specific plan. Each plan shows its status by city.
What if I already have a builder?
We'll help you get the building permits, but we build every A Mayberry ADU ourselves. That's how we keep the quality consistent and stand behind it with our warranty after construction.
