Does a garage home office need a permit in San Diego?
Yes. Converting a garage to habitable space, including a home office or gym, requires a building permit in San Diego County. The permit covers the wall infill, HVAC, and electrical work and confirms the space meets Title 24 energy compliance. The crews we refer manage the permit as part of the scope.
What is the best flooring for a garage gym conversion in San Diego?
Rubber mat flooring over a moisture-barrier-treated slab is the most practical choice for a home gym. It protects the slab from dropped weights, cushions impact, and is easy to clean. Interlocking rubber tiles are a lower-cost option for lighter use. The licensed pro you hire reviews slab condition and moisture before specifying the floor system.
