The California ADU Permit Guide
For California homeowners. Current to the law in force in August 2026.
What's Inside
- Where you stand. Ten situations, one row each, routed to the pages that decide yours.
- The numbers that decide your design. The size thresholds state law draws, and what each one buys you.
- The process. Approval, clocks, sizes and fees — each with its code section cited in the guide.
- The money you do not have to spend. The fees, waivers and programs most owners never claim.
- Six kits. From choosing your route to pricing your own city's fees.
What This Guide Does
Every figure is quoted from the Government Code. The guide asserts no dollar saving, because California publishes no statewide fee schedule — Kit 4 computes yours from your own city's. The entitlements in it are worth the same to everyone; the fees are not, and it says so on page one.
