About us

What is StructBuilder?

StructBuilder is a Los Angeles ADU design-build company. We plan, permit and build backyard homes, garage conversions and second-story units for homeowners, with one team from the first call to the final inspection.

Can I build an ADU on my lot?

Most single-family lots in Los Angeles can host at least one ADU. What decides the outcome is the lot itself: space, utilities, easements and fire or flood zones. Our free feasibility check answers it for your address.

FAQ

Questions homeowners ask us.

How much does it cost to build an ADU in Los Angeles?

Cost depends on size, type (detached, garage conversion or second story), site access, utilities and finishes. After the free feasibility check, StructBuilder gives a written range for your lot. [Insert StructBuilder price ranges here.]

Can I build an ADU in my backyard in Los Angeles?

Usually, yes. California law requires cities to allow ADUs on most residential lots and caps side and rear setbacks at 4 feet for new construction. Lot size, utilities, easements and fire or flood zones decide what fits. The feasibility check answers this for your address.

Do I need extra parking for an ADU?

Often not. State law does not allow cities to require replacement parking when a garage is converted, and no parking can be required for an ADU converted from existing space or near transit. Confirm your address with us.

Can I build now and pay later?

For qualified California homeowners, yes: StructBuilder covers the payments until end of 2028, so the ADU is built before the first payment is due. Eligibility depends on the project and the property equity profile, and is checked during the free call.

How long does the process take?

It is split in stages: feasibility, design, permits, construction and inspection. [Insert real durations from StructBuilder projects.]

Who handles permits and inspections?

StructBuilder prepares and submits the permit package, answers plan-check comments and schedules inspections, so you deal with one contact.
