Solid ADU is active in Boyle Heights and the immediate area, including Lincoln Heights, El Sereno and Montecito Heights. We can guide your detached ADU too, from first advice through the final LADBS inspection, with the build done by a licensed contractor from our network.
Just east of the LA River, Boyle Heights is one of the oldest neighborhoods in the city, with Victorian houses, Craftsman bungalows and early 1900s cottages on compact lots, many of them backing onto alleys with a garage or shed at the rear. Multigenerational living is a way of life here, and that is exactly what a permitted ADU supports: grandparents, adult kids or a tenant get a real home with its own kitchen and bath, while the family keeps the property. Because many Boyle Heights garages are older structures, the feasibility check matters, we look at the foundation, framing and utilities honestly before proposing a conversion or a rebuild. Everything is permitted and inspected through LADBS, so the finished unit is legal, safe and adds lasting value to the lot. Think of Victorian-era houses, Craftsman bungalows, early 1900s cottages and alley-access rear garages: 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.

Detached ADU in Boyle Heights: 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.
You can find the full overview on our detached ADU page.
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 Boyle Heights
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
