Do you own a home in Eagle Rock and are you considering an attached ADU? Then you are in the right place. Solid ADU guides these projects throughout Eagle Rock and also in Highland Park, Glassell Park and Mount Washington, and matches you with a vetted licensed contractor who does the building.
Tucked between Glendale and Pasadena, Eagle Rock is a family neighborhood of 1920s Spanish bungalows and postwar ranch homes spread along the streets on either side of Colorado Boulevard. Lots here tend to be a bit wider and flatter than elsewhere on the Eastside, with generous backyards and detached one or two car garages. That extra room gives you options: convert the existing garage into a rental or in-law unit, or build a new detached ADU and keep your parking. Many Eagle Rock owners are planning for the long term, a place for parents, a returning college kid or steady rental income, and a permitted unit fits that plan. Every project runs through LADBS, and we manage the permits, construction and inspections for you from start to finish. Think of 1920s Spanish bungalows, postwar ranch homes, Craftsman houses and detached backyard garages: we tailor the approach to the type of home and the condition of your lot and existing structures.
An attached ADU (Accessory Dwelling Unit) is a complete, self-contained home that shares at least one wall with your main house. It has its own entrance, kitchen, bathroom and living space, so it can be rented out or used by family while everyone keeps their privacy. You can build it as a new addition on the side or rear of your house, or convert an existing part of your home, such as a rear wing or an oversized family room, into a separate unit.
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.

Attached ADU in Eagle Rock: what is possible
Free feasibility check
We review your lot, existing structure, setbacks and utility locations, and tell you what size and layout of attached ADU is realistic before you spend anything on design.
Design and floor plans
We help you shape the unit around how it will be used: rental, family housing or home office with living space. You review the layout and finishes before anything moves toward permitting.
LADBS plan check and permits
Your contractor's team prepares the full plan set with structural, Title 24 energy and site documents and submits it to LADBS plan check. We guide you through the process, track corrections and keep the application moving through to permit issuance.
Connecting to the existing structure
An addition has to carry its own loads and tie cleanly into your house. Your contractor handles the foundation, framing and roof connection so the new unit and the existing structure work together, verified by inspection.
Converting part of your home
Instead of building new, your contractor can turn an existing section of the house into the ADU: closing interior openings, adding the separate entrance and upgrading the space to full dwelling standards.
Private entrance
Every ADU needs its own exterior entrance. The plans place it for privacy on both sides, with its own path, address marking and lighting, so tenants never walk through your space.
Fire and sound separation
The wall and any floor or ceiling between the units are built as rated assemblies: layers of fire-resistant drywall, insulation and sealed penetrations that slow fire spread and block everyday noise.
Plumbing, electrical and HVAC
Your contractor runs new supply, drain and electrical lines, adds or extends panels where needed, and installs efficient heating and cooling, typically a ductless mini-split, sized for the unit.
Kitchen and bathroom build-out
A full kitchen and bathroom are what make it a dwelling. Your contractor builds both complete: cabinets, counters, appliances, fixtures, waterproofing and tile.
You can find the full overview on our attached ADU page.
Why invest in an attached ADU?
Most homeowners we talk to want the extra space or rental income but get stuck on the same points. Recognize any of these?
- You are not sure whether your lot even qualifies for an attached ADU, or how big it could be.
- You need rental income or space for family, but a detached backyard unit does not fit your lot.
- The permit process feels like a black box: plan check, corrections, inspections, all with their own rules.
- You have talked to an architect and a contractor separately and got two stories that do not line up.
- You do not know how to vet a contractor, or which quote you can actually trust.
- You worry the addition will look bolted on and hurt the value of your home.

Attached ADU costs in Eagle Rock
What an attached ADU costs depends heavily on the route you take. Converting an existing part of the house that already has a roof and slab is a different project from building a new addition with its own foundation. That is why you will not find standard prices here: for your situation they would almost always be too high or too low.
- New addition or conversion of existing space
- The size and layout of the unit (studio, one or two bedrooms)
- Foundation and structural work needed to tie into the existing house
- The condition of the existing structure, slab and roof at the connection point
- How far water, sewer and electrical lines must be extended, and whether the panel needs upgrading
- The fire and sound separation assemblies between the two units
- Kitchen and bathroom scope and the finish level you choose
- Matching the exterior: stucco, siding, roofing and windows
