Built for Manhattan Beach Homes
Small lots, big ambitions. Sand Section parcels are typically narrow, with tight side setbacks, so a plunge pool, a spa, a roof deck and a stair tower all have to be resolved as one three-dimensional puzzle. Walk-street addresses have no vehicle frontage at all, which makes staging and material handling a design decision. We plan the coastal permit and the crane pick together.
Tight and narrow near the beach, with larger, steeply sloped view parcels up the hill and wider conventional lots inland.
We are a design-build team, which means the people who draw your project are the people who build it. Design, engineering, permits and construction run through one project manager and our own crews, so nothing gets lost in a handoff between a salesperson and a subcontractor. We are licensed, bonded and insured, CSLB license #1119054 .
Permits in Manhattan Beach: Building permits are issued by the Building and Safety Division of the City's Community Development Department, with applications accepted through the Citizen Self Service portal. Manhattan Beach has a certified Local Coastal Program, so the City itself issues Coastal Development Permits under the Coastal Development Permit Procedures chapter of that program, and certain decisions remain appealable to the California Coastal Commission.
Chapter A.96 of the Local Coastal Program decides whether a Coastal Zone project needs a Coastal Development Permit or qualifies for an exemption, so we check the City's Coastal Zone map first. Review time varies with scope, and a plan check expires if no permit is issued within 12 months of the application.
Permit details checked September 2026 against California Coastal Commission . Rules change, so we confirm them again for your parcel.

Local Conditions
What to Know in Manhattan Beach
These local conditions change the scope, the schedule and the budget.
01
Loose beach sand and dune deposits across much of the west side require engineered shoring, and often caissons, before excavation for a basement, pool or equipment vault.
02
Walk-street properties have no vehicle frontage, so gunite, steel, spoil and finish materials move by hand, conveyor or crane from an adjoining street.
03
Persistent salt air corrodes fasteners, equipment housings and unprotected metal, pushing specification toward marine-grade hardware and coated components.
04
Hill Section parcels fall steeply from street to rear, so outdoor living stacks vertically across decks and terraces instead of spreading out.

Questions
What Manhattan Beach Homeowners Ask
Who issues the permits for this work in Manhattan Beach?
City of Manhattan Beach Community Development Department, Building and Safety Division. Building permits are issued by the Building and Safety Division of the City's Community Development Department, with applications accepted through the Citizen Self Service portal.
Manhattan Beach has a certified Local Coastal Program, so the City itself issues Coastal Development Permits under the Coastal Development Permit Procedures chapter of that program, and certain decisions remain appealable to the California Coastal Commission.
Chapter A.96 of the Local Coastal Program decides whether a Coastal Zone project needs a Coastal Development Permit or qualifies for an exemption, so we check the City's Coastal Zone map first. Review time varies with scope, and a plan check expires if no permit is issued within 12 months of the application.
We prepare the drawings, make the submittal and handle plan-check corrections ourselves, so you are not the one chasing plan check.
What makes building in Manhattan Beach different?
Tight and narrow near the beach, with larger, steeply sloped view parcels up the hill and wider conventional lots inland. One local condition that shapes the work: Loose beach sand and dune deposits across much of the west side require engineered shoring, and often caissons, before excavation for a basement, pool or equipment vault.
Which parts of Manhattan Beach do you work in?
All of it, including Sand Section, Tree Section, Hill Section and El Porto. Our crews run every job out of our Cahuenga Pass base in Los Angeles, with our own people on site.
What does an ADU or addition cost in Manhattan Beach?
Detached ADU: generally $150,000 to $400,000+ across Southern California. What moves it is square footage, finish level, utility runs, and site access; garage conversions typically run well below a ground-up detached build. We give line-item pricing after seeing the site rather than quoting a number over the phone.
How long does an ADU take start to finish?
Plan a realistic year. Design and engineering typically take one to three months, city plan check and corrections add several more, and construction usually runs four to eight months depending on size and site access.
Is a garage conversion cheaper than a detached ADU?
Usually yes, and often substantially, because the foundation, walls and roof already exist. The trade-offs are that you lose the garage, and older slabs and framing sometimes need upgrading to meet current code.
Can I rent the ADU out?
California ADU law is designed to allow long-term rental, and an ADU is one of the few ways to add rentable square footage to a single-family lot. Short-term rental rules vary by city, so confirm your local ordinance before counting on that income.
Do you handle the permits?
Yes. Plans, engineering, Title 24 and the city submittal are all handled in-house, including responding to plan-check corrections. That is a service we sell on its own, so it is not something we hand off.
