Do you own a home in Playa del Rey and are you considering a detached ADU? Then you are in the right place. Solid ADU guides these projects throughout Playa del Rey and also in Westchester, Del Rey and Venice, and matches you with a vetted licensed contractor who does the building.
Playa del Rey is a small beach community tucked between the Ballona Wetlands, the bluffs and the ocean, with a quieter feel than its Westside neighbors. Housing splits between mid-century homes up on the bluffs and older beach cottages on the compact lots of the lowlands near the sand. On lots this tight, a garage conversion is often the only realistic way to add living space, and it is a popular one: owners create guest quarters, home offices and rentals that benefit from the proximity to the beach, LAX and Playa Vista. Bluff properties need a careful look at slope and access before planning, which is exactly what our feasibility check covers. We tell you up front what your lot supports, then handle the LADBS process from plans to final inspection. Think of mid-century bluff homes, older beach cottages, postwar single-family homes and coastal duplexes: we tailor the approach to the type of home and the condition of your lot and existing structures.
A detached ADU (Accessory Dwelling Unit) is a stand-alone home in your backyard, fully separate from your main house. It has its own entrance, kitchen and bathroom, which makes it ideal as a long-term rental, a home for parents or adult kids, or a private office and guest house in one.
There is no pressure to decide right away. We first discuss your plans free of charge, check feasibility for your lot, and then match you with a vetted licensed contractor who sends you a detailed fixed proposal. That way you know exactly where you stand before you commit to anything.

Detached ADU in Playa del Rey: what is possible
Free feasibility check
Before you spend anything, we review your lot: zoning, setbacks, existing structures, slope, access and utility locations. You get a clear answer on what size and placement are realistic on your property.
Design and architectural plans
Together with you we shape the layout, and design professionals turn it into full construction drawings: floor plan, elevations, structural details and the energy calculations California requires. You approve the design before anything is submitted.
LADBS plan check and permits
We guide you through the LADBS permit process: your contractor's team prepares and submits the plans, responds to plan check corrections and pulls the building permit. You do not have to stand in line or decode correction letters, and you always know where the application stands.
Site preparation and grading
Your contractor clears the build area, demolishes and hauls away any old sheds or slabs, and grades the site so water drains away from the new unit. On sloped lots, retaining and drainage solutions are planned up front.
Foundation work
Most detached ADUs sit on a concrete slab foundation; some sites call for a raised foundation instead. Your contractor forms, reinforces and pours the foundation and has it inspected before the structure goes up.
Framing and structural shell
For a site-built ADU, your contractor frames the walls, roof and openings on your lot, following the engineered plans. Shear walls and hardware are installed to meet California's seismic requirements.
Prefab and modular ADU installation
Prefer a factory-built unit? Our network includes contractors who prepare the foundation and utilities, coordinate delivery and crane placement, and complete the on-site connections and finish work so the unit is approved for occupancy.
Utility connections
Your contractor trenches and connects water, sewer and electrical service from your main house or the street to the new unit. Where the existing electrical panel is too small, the upgrade is included in the plan.
Roofing, windows and exterior finish
The shell is closed in with roofing, dual-pane windows, exterior doors and your choice of siding or stucco. The exterior can match the look of your main house or give the ADU its own character.

Why invest in a detached ADU?
Most homeowners we talk to want a backyard ADU but get stuck before the project even starts. Does any of this sound familiar?
- You are not sure whether your lot even qualifies for a detached ADU, or how big it could be.
- The permit process feels like a maze: plan check, corrections, inspections, and no idea how long each step takes.
- Contractors give you vague ballpark numbers that keep shifting, so you cannot budget with confidence.
- You would have to coordinate an architect, an engineer and multiple trades yourself, without knowing who is responsible when something goes wrong.
- Nobody can tell you up front what the utility connections will involve, or whether your electrical panel can handle a second home.
- You have heard stories of backyard projects that stalled for months halfway through construction.

Detached ADU costs in Playa del Rey
What a detached ADU costs depends heavily on your lot and your choices. A compact studio on a flat lot with utilities nearby is a very different project from a 1,200 sq ft two-bedroom on a slope that needs an electrical panel upgrade. That is why you will not find standard prices here: for your situation they would almost always be too high or too low.
- The size of the unit in square feet and the number of bedrooms and bathrooms
- Site conditions: slope, soil, access for equipment and material deliveries
- The foundation type your lot requires
- Site-built construction versus a prefab or modular unit
- The distance from the unit to water, sewer and electrical connections
- Whether your electrical panel needs an upgrade to serve a second dwelling
- The finish level of the kitchen, bathroom and flooring
- Design complexity: roof lines, ceiling heights, custom features
