Remodeling in Glendale

Glendale's hilly terrain can add foundation and grading costs. The city has invested in streamlined permitting for ADUs, making it one of the easier LA-area cities for accessory dwelling construction.

California allows ADUs on most residential lots since 2020. An ADU adds living space and rental income. Cities must approve or deny within 60 days of a complete application.
