Burbank permitted 1,401 ADUs from 2014 to 2024 — among the most active markets in California. Here's what it costs, what's allowed, and who builds them.
All-in design-build estimates (architecture + permits + construction + soft costs). Real quotes vary by lot conditions, finishes and contractor — get at least three before signing.
Per-square-foot ranges reflect 2026 pricing in the los angeles market. Permit fees ($5–25k), site work ($10–40k) and high-end finishes can push totals 20–40% higher. See cost methodology for the full regression model and the 8 California builder-pricing sources it's calibrated against.
California state law sets a floor that every city must meet. Burbank may allow more than the minimums shown — confirm with the Burbank planning department before finalising plans. See how we verify city-specific ordinance data.

Most Burbank ADU projects fall in a $100,000–$400,000+ range, all-in (design + permits + construction). The big drivers are size, type (detached costs more than a garage conversion), and finish level. See the per-type cost table above for typical ranges in this market.
Yes — every ADU in California requires a building permit. Burbank processes ADU applications under the state's 60-day ministerial review rule (no public hearings, no discretionary review for code-compliant designs). Permit fees vary but typically run $5,000–$25,000 depending on size and impact fees.
State law guarantees a minimum allowance of 850 sqft (studio/1BR) or 1,000 sqft (2+BR). Many California cities allow larger detached ADUs — check the Burbank planning department or the ordinance link in our rules table above for the local maximum.
No, not for an ADU. AB-976 (effective 2023) extended the state's ban on owner-occupancy requirements for ADUs through January 1, 2030 — California cities may not require an owner to live on the property as a condition of permitting an ADU during that window. JADUs are different: owner-occupancy of either the primary residence or the JADU itself is required by state law throughout the JADU's life.
A JADU (Junior ADU) is a unit ≤500 sqft created within an existing single-family home, sharing a wall with the main residence. JADUs are cheaper and faster to build, but they require owner-occupancy of either the main house or the JADU. Most homeowners build a separate ADU for rental flexibility.
According to the California ADU permit dataset compiled by BuildinganADU.com, Burbank permitted 317 ADUs in 2021, the peak year on record (2013–2022). California-wide ADU permits have grown roughly 20× over that period — homeowner demand is outpacing every other housing-supply tool the state has tried.
