Room additions in Glendale are one of the most effective ways to add space to a home without the disruption and expense of moving. With strong property values, tight inventory, and a housing stock that often has the lot space to support an addition, Glendale is an ideal market for expanding rather than relocating. APLA Construction (CA Lic #1136359) handles room additions throughout Glendale — from single bedroom additions to full second-story builds — managing design, permits through the City of Glendale, and construction under one contract.

Room additions in Glendale require permits from the City of Glendale Community Development Department — not LADBS. Glendale has its own independent permitting process. A room addition requires structural, architectural, electrical, and plumbing permits. Plan check review at Glendale for room additions typically takes 6–10 weeks. APLA prepares and submits all required documentation, responds to plan check corrections, and coordinates all inspections.
A significant portion of Glendale sits in hillside terrain (Chevy Chase Canyon, San Rafael Hills, Verdugo Mountains). Room additions on hillside properties require geotechnical soil reports and engineered foundations. APLA coordinates geotechnical engineering as part of the design phase for hillside addition projects in Glendale.
Glendale zoning sets lot coverage and setback requirements that constrain where an addition can be placed. APLA evaluates lot coverage, setbacks, and floor area ratio compliance during the initial feasibility assessment before any design work begins.
A bedroom addition in Glendale costs $88,000–$165,000. A primary suite addition costs $130,000–$240,000. A partial second story addition costs $230,000–$400,000. Hillside properties may add $15,000–$35,000 for geotechnical engineering and foundation work.
8–20 months total depending on scope. The City of Glendale permit process for room additions takes 6–10 weeks for plan check approval. Construction takes 4–8 months. Hillside projects with geotechnical requirements may run longer.
