Home Additions in San Diego, CA
More house, without moving.
Military households, tech money, and coastal-zone regulation create a renovation market where the permit path matters as much as the design.
An addition has to tie into the existing structure cleanly or it shows. We match you with builders who handle the foundation, framing, and roofline tie-in, plus the zoning and permit gauntlet that scares off lesser crews.
