What applies to your lot
Building an ADU in Carson
Who approves your ADU
City of Carson: ADUs follow Section 9122.1 of the Carson Municipal Code. State law applies everywhere: a decision within 60 days of a complete application, no public hearing, and at least 800 sq ft with 4 ft side and rear setbacks.
Garage or backyard
Many homes have an attached garage. Converting it is often the fastest path; a detached unit keeps the garage and adds more space.
No impact fees under 750 sq ft
An ADU under 750 sq ft pays no impact fees. Above that, fees are proportional to the size of the house.
One ADU plus one JADU
On a single-family lot, an ADU and a junior ADU inside the house can be built together.
