Converting a garage into an ADU is the fastest, lowest-cost path to a permitted living unit in Pasadena. The existing slab, walls, and roof do most of the structural work — keeping budgets tight and timelines short.
Pasadena's charming neighborhoods, excellent schools, and proximity to downtown LA make it a prime market for ADUs. High property values mean strong rental returns and significant equity gains from ADU construction.
