ADU permits in Glendale
How to build a ADU in Glendale: permit pathway through Glendale Community Development Department, drawings required, local watch-outs, and a free address-level wizard for your Glendale lot.
Glendale context
Glendale's ADU ordinance lives in Glendale Municipal Code Title 30. The city is geographically split by the 134 freeway: south of the 134 is denser, more walkable, and largely on the flats; north of the 134 climbs into the Verdugo foothills with hillside-area rules. Plan check is typically 45-60 days for ADUs from a complete submittal. The city maintains an online portal for ADU submittals.

Glendale watch-outs for ADU
Overlays that hit a meaningful share of Glendale lots
Very High Fire Hazard Severity Zone (VHFHSZ)~22% of parcels
Verdugo foothill parcels north of Mountain Street + the Chevy Chase area sit in the VHFHSZ. Chapter 7A construction adds roughly 7% to build cost.
Hillside Development Standards (HDS)~28% of parcels
Slopes over 25% trigger lot-coverage + ridgeline-protection rules + a geotech / soils report. Common combo with VHFHSZ.
Adams Hill conservation overlay~4% of parcels
Small but architecturally-protected pocket east of downtown. Exterior-visible ADUs face design review for compatibility with historic Craftsman / California-bungalow patterns.
Local quirks
Verdugo hillside requires a soils report
If your lot is north of Mountain Street and slopes more than 25%, expect to budget $3,000-$8,000 for a geotechnical / soils engineering report before the building permit issues. Adds 4-8 weeks to your schedule.
Glendale Unified school fees apply
Glendale Unified School District (GUSD) charges school facility fees on new ADUs over 500 sqft, typically around $4.79/sqft.
South Glendale walkability supports the transit parking exemption
Lots in central + south Glendale within 0.5 mi of a major transit corridor (Brand Blvd, Colorado Blvd, the Beeline trunk routes) qualify for the state Accessory Dwelling Unit (ADU) parking exemption. Confirm with Community Development for your specific parcel.
