Building an ADU in Eagle Rock
Eagle Rock mixes hillside streets with flatter blocks of older homes, and that split shapes what an ADU costs here. On a flat lot with an old detached garage, a conversion or a new backyard unit can be simple. On a slope, grading and foundations become a bigger part of the budget.
ADU Resource Center designs, permits and builds ADUs in Eagle Rock with one in-house team, about fifteen minutes from our Glendale office. Here we turned a two-car garage into a 2-bedroom, 2-bath ADU with an added extension and 9.5-foot ceilings, and built a blue backyard cottage painted to match the main house.
You get a fixed quote before construction starts, one project manager from design through final inspection, and help lining up financing.

Local know-how
What to know before building in Eagle Rock.
City of LA permits
Eagle Rock is part of the City of Los Angeles, so plans go through LADBS. LA's Standard Plan program offers pre-approved designs that can shorten review.
Hillside lots
Sloped lots can need a soils report, retaining walls and an engineered foundation. We plan for it in the first design pass so it's in your quote from the start.
Fire hazard zones
Parts of the Eagle Rock hills are in very high fire hazard severity zones, which means ignition-resistant materials and specific roof, vent and siding requirements. We design to those rules from day one.
Garage conversions
Older Eagle Rock homes often have detached garages. Converting one reuses the existing structure, which usually costs less than building new. See garage conversion cost.

Questions
Eagle Rock ADU questions, answered.
Still have a question? Ask us during your free consultation.
Can I build an ADU in Eagle Rock?
Most single-family lots in Eagle Rock can add a detached ADU, an attached ADU or a garage conversion, and often a junior ADU inside the house. Hillside lots and fire hazard zones add steps. We check your lot against current City of Los Angeles and state rules on your free consultation, since ADU rules change from time to time.
Who issues ADU permits in Eagle Rock?
Eagle Rock is a neighborhood of the City of Los Angeles, so ADU plans go through LA's Department of Building and Safety (LADBS). LA also runs a Standard Plan program of pre-approved ADU designs, which can shorten design review. We prepare and submit the plans and answer every correction.
How much does an ADU cost in Eagle Rock?
We build at a flat construction rate of $275, $300 or $325 per sq ft for basic, mid-range or luxury finishes, so a 600 sq ft one-bedroom runs roughly $165K–$195K in construction. Garage conversions have their own rates of $235–$285 per sq ft. Hillside work, retaining walls or long utility runs can change the fixed quote for your property.
Is a hillside lot a problem for an ADU?
Not necessarily, but it usually costs more. Sloped lots can need grading, retaining walls and an engineered foundation. Some Eagle Rock homeowners we've worked with chose a flat lot or a garage conversion for exactly this reason. We price the site work up front.
Can I convert my garage into an ADU in Eagle Rock?
Often, yes. We converted a two-car garage in Eagle Rock into a 2-bedroom, 2-bath ADU with an added extension. Older garages sometimes need foundation, framing or electrical work first, and we check that before you commit.
