How It Works
San Diego ADU Planner helps homeowners in the San Diego area get in touch with independent ADU contractors. We do not design, permit, or build ADUs ourselves. Here is what happens when you send a request.
Step 1: Tell us about your project
Use the quote request form. We ask for your name, phone number, city, the type of ADU you have in mind, and its rough size. Email and extra details are optional, but they help.
Step 2: We pass your request along
We send your request to an independent contractor who works in your area. That contractor may pay us a referral fee. You do not pay us anything.
Step 3: A contractor may reach out
The contractor may call, text, or email you about your project. We cannot promise that a contractor will contact you or when they will do so.
Step 4: You decide
Ask questions, compare quotes, and take your time. Hiring a contractor is your choice. A referral is not an endorsement, so check any contractor yourself before you sign. You can look up a contractor's license with the California Contractors State License Board.
What helps a contractor quote your ADU
The more a contractor knows up front, the more useful the first talk will be. Have these ready if you can:
- Your lot. Lot size, slope, and where on the lot you want the ADU.
- Your zone. Your zoning, and whether your property is in a coastal zone or a fire hazard area. In the City of San Diego, these can change setbacks and permits [1].
- The type. Detached, attached, garage conversion, or JADU.
- The size. A rough square footage. In the City of San Diego, new attached and detached ADUs can be 150 to 1,200 square feet [1].
- Your goal. Rental income, family, a home office, or something else.
- Your timeline and budget. Even a rough range helps. See our ADU cost guide for published ranges.
