What applies to your lot

Building an ADU in Glendale

Who approves your ADU

City of Glendale: ADUs on single-family lots follow Section 30.34.080 of the Glendale Municipal Code. A Planning clearance comes before the building submittal. State law applies everywhere: a decision within 60 days of a complete application, no public hearing, and at least 800 sq ft with 4 ft side and rear setbacks.

Fire zones

According to the Glendale Fire Department, if any part of a parcel is in a Very High Fire Hazard Severity Zone, the whole parcel is treated as such: Class A roof, ignition-resistant materials and defensible space.

Above 800 sq ft

An ADU larger than 800 sq ft must also meet the base zone standards, such as lot coverage. It often decides whether a 1,000 sq ft unit fits.

Slopes

Hillside lots can require soils reports and more structure. We assess this at the visit, before any design.
