Redondo Beach ADU contractor.

It's the question everyone asks first, and the honest answer is: it depends on what you build. A garage-conversion ADU, a detached new-build ADU, and a junior ADU are different projects with different price tags — then site work, sewer, and finish level move the number further. We don't quote a figure before we've walked the lot. What we do on the free consult is give you an honest range and design backward from your real budget, so you get an ADU that actually builds for the number you have — and one that adds rental income and resale value, which is why most Redondo owners build.

We pick the type on the lot walk based on your goal — rental income, multi- generational living, or a home office — and what your lot will actually hold.

Redondo isn't one place to build. North Redondo — the old Golden Hills and TRW flats — is mostly single-family R-1 on flatter, regular lots, where detached ADUs and garage conversions go in cleanly. South Redondo, toward the pier and harbor, carries a lot of R-2 and R-3 multi-family zoning and older infrastructure — and California law lets you add ADUs on those lots on top of the existing units, which makes many duplex and triplex parcels far more flexible than owners expect. Our South Redondo Triplex is exactly the kind of dense, infill-aware work that a multi-family ADU calls for. The Riviera runs uphill, with view lots and slope to manage.

The lever that matters is the ministerial ADU pathway — when a project qualifies, Redondo Beach reviews it administratively against objective standards instead of at a discretionary hearing, which is faster and far more predictable. We draw to Redondo Beach Community Development's plan-check conventions up front and run the corrections cycle, typically 8–14 weeks, then 5–9 months of construction. Two Redondo-specific items we check early: sewer capacity on older South Redondo laterals, and parking, which state law usually waives for garage conversions and transit-adjacent lots. For exactly what the counter looks for, read our field notes on ADU permits in Redondo Beach.

The expensive failures on ADUs happen in the handoff — a designer draws something the lot or zoning can't carry, or the permit set doesn't match what gets built. Because the people who draw your ADU are the people who build it, that gap doesn't exist: one contract, one schedule, one point of accountability. We've built in Redondo for decades — the South Redondo Triplex, the Redondo Beach Home, and Broadway Lofts — and the same team serves the rest of Redondo Beach and the South Bay, under one license since 1978.
