What to Expect from ADU Contractors in Gardena
An accessory dwelling unit is a small building with all of a large one’s obligations. It needs its own foundation, its own utility connections, and its own path through plan check — and unlike a remodel, it adds a dwelling, so the questions about setbacks, parking, fire separation and utility capacity are asked seriously.
In practice the schedule is dominated by approvals rather than construction. State law has narrowed what a city can refuse and set time limits on review, but Building and Safety Division still decides what your specific parcel allows. Confirm your local rules first — a contractor who tells you the rules without asking your address has not looked.
- Feasibility against setbacks and lot coverage
- Foundation and full structural shell
- Separate utility connections and metering
- Plan check and impact fee handling
- Kitchen and bathroom fit-out
- Final inspection and certificate of occupancy
Why CSLB Licensing Matters
An ADU is a new structure, not an alteration, which puts it under Class B (General Building). CSLB defines a general building contractor as one whose work involves structures requiring at least two unrelated trades — the classification that covers building something from the ground up.
Every contractor on this page holds an active Class B (General Building) licence recorded at a Gardena address, with the number linked to the CSLB record. Check it before you pay for design work. The register will not tell you whether someone has built an ADU before, so ask directly and ask to see one.
What the register cannot tell you is whether a contractor has taken an ADU through plan check in your jurisdiction specifically. Requirements and review times differ between cities and unincorporated county areas, and familiarity with one department is worth real money in weeks saved. Ask how many ADUs they have completed, where those were, and whether any needed revisions after submission. Ask as well whether the price includes impact fees and utility connection charges — those are frequently excluded, they are not small, and discovering it at invoice stage is the most common unpleasant surprise on an ADU.
Every licence number below links to its record at cslb.ca.gov, where you can confirm status and expiry yourself.

Frequently Asked Questions
What licence does building an ADU require?
An ADU is new construction, so it falls under Class B (General Building) — the general building classification for structures involving two or more unrelated trades. This page lists contractors the register records with that classification at a Gardena address.
How many general building contractors are registered in Gardena?
The register shows 183 with an active licence in this classification at a Gardena address, and 22,043 across Los Angeles County. The same pool covers general contracting work, so those pages list the same contractors.
Has True Local Pros confirmed these contractors build ADUs?
No. The register records classification and status, not project history or specialism, and we do not claim more than it holds. Ask each contractor how many ADUs they have completed and request an address you can go and look at.
Who decides what I can build on my lot?
Building and Safety Division. State law sets the outer limits, but setbacks, height, parking and utility requirements are applied locally and vary by parcel. Ask them before you commission drawings.
