“The garage-to-ADU conversion detail that most contractors skip: thermal envelope. A garage was never designed to be conditioned space. The slab has no insulation. The walls have no insulation. You need to address this before installing HVAC or your utility bills will be double what the tenants expected. Rigid insulation under a new finish floor is the correct approach.”
Get a title report before converting a garage to an ADU. Some properties have recorded Conditions, Covenants, and Restrictions (CC&Rs) from original tract development that prohibit residential use of detached garage structures. These CC&Rs are separate from zoning and LADBS rules — they're private law that runs with the land.
Most garage conversion projects in Glendale that involve structural, electrical, plumbing, or mechanical changes require LADBS permits. Working without required permits in Glendale creates unpermitted improvement disclosure obligations at sale. Your contractor should pull all required permits before work begins — this protects both your investment and your legal standing.
Verify CSLB license at cslb.ca.gov, request 3+ references from completed garage conversion projects in Glendale or nearby, confirm active insurance and worker's comp coverage, and ensure the contractor can explain the permit process for your specific project. Contractors who know Glendale's local conditions, permit office staff, and inspection procedures complete projects faster with fewer complications.
