ADUs in Manhattan Beach
Every ADU is a small house with all the same complexity. We've built detached, attached, and garage-conversion ADUs across the South Bay — and we're fluent in the local lot constraints, setbacks, and SB-9/SB-10 timelines that trip up out-of-town builders.
Manhattan Beach holds some of the South Bay's most demanding homeowners and highest finish expectations. From Sand Section walk streets to the larger Hill and Tree Section lots, the bar is high and the detail shows.

Building in Manhattan Beach
We know the local ground.
Design review, careful setback and height math, and Coastal Zone rules on the west side all shape what's buildable. Basements are a common move here to add square footage without going up or out.

Frequently asked
Common questions.
Do you take on adus projects in Manhattan Beach?
Yes. Manhattan Beach is squarely in our South Bay service area, and adus work is one of our core services. Design review, careful setback and height math, and Coastal Zone rules on the west side all shape what's buildable. Basements are a common move here to add square footage without going up or out.
How long does an ADU take?
Plan on 4–8 months from permit-ready drawings to keys, depending on size and city. Permitting itself can take 2–4 months in some South Bay cities.
Will the rental income cover the build?
Sometimes. We'll model realistic build cost vs. realistic local rents before you commit so you're not guessing.
Do you do garage conversions?
Yes. Garage and JADU conversions are often the fastest path to permitted square footage if the existing structure is sound.
