Building an ADU in Glendale
Glendale homeowners build ADUs for the same reasons we hear across LA: rental income, room for aging parents, or a place for grown kids to live close by. What makes Glendale different is the land. Many lots sit on hillsides near the Verdugos, others are tight older parcels in the flats, and both shape what you can build and what it costs.
ADU Resource Center designs, permits and builds ADUs in Glendale with one in-house team. We've completed four ADUs here, from a two-story modern unit to a courtyard design and a pool house, and dozens more next door in Pasadena, Burbank and Eagle Rock.
You get a fixed, itemized price before we build, a project manager who sends weekly updates, and financing options so you don't need the full cost saved up front.

Local know-how
What to know before building in Glendale.
Hillside lots
Sloped lots often need a soils report and engineered foundation. We plan for it in the first design pass so the price you see is the price you pay.
Fire hazard zones
Parts of Glendale near the Verdugo Mountains 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 Glendale homes often have detached garages that convert well. No new setbacks are required for an existing structure, which can save months and tens of thousands of dollars.
State rules work in your favor
California guarantees at least an 800 sq ft ADU with 4-foot side and rear setbacks, allows up to 1,200 sq ft detached, and requires a decision on a complete application within 60 days.

Questions
Glendale ADU questions, answered.
Still have a question? Ask us during your free consultation.
Can I build an ADU on my Glendale property?
Most single-family lots in Glendale can add a detached ADU, an attached ADU or a garage conversion, plus a junior ADU inside the house. State law sets the baseline: an ADU of at least 800 sq ft with 4-foot side and rear setbacks can't be blocked by local lot-coverage rules. Hillside lots, slopes and fire-zone parcels add steps, which we check on your free consultation.
How big can an ADU be in Glendale?
Under California law a detached ADU can be up to 1,200 sq ft, and a junior ADU (inside the main house) up to 500 sq ft. Attached ADUs are generally capped at 50% of the main home's size or 1,200 sq ft. Your exact maximum depends on your lot, and we confirm it before design starts.
How long do ADU permits take in Glendale?
State law requires the city to approve or deny a complete ADU application within 60 days. In practice, plan check plus corrections usually puts design-and-permit time at 2–4 months. Construction then takes about 4–8 months depending on size and finishes.
How much does an ADU cost in Glendale?
We build at $275, $300 or $325 per sq ft for basic, mid-range or luxury finishes. A 600 sq ft one-bedroom is roughly $165K–$195K in construction. Hillside foundations or long utility runs can add cost; we price those up front so there are no surprises.
Can I convert my garage into an ADU in Glendale?
Yes. Garage conversions are often the fastest and most affordable ADU because the structure already exists, and state law doesn't require new setbacks for converting an existing garage. We've converted garages across Glendale, Burbank and Eagle Rock.
Do you handle the Glendale permits?
Yes. We prepare the plans, submit to the City of Glendale, respond to every plan-check correction and pull the permits. You get one point of contact from design through final inspection.
