Garage Conversion Scope Audit for San Diego, CA

Reviewed May 26, 2026

Garage conversion bids are only comparable when they include the code work that turns storage space into legal living space. Separate shell upgrades, insulation, egress, HVAC, electrical, plumbing and finish scope before comparing prices. Use the $58,001 midpoint as a planning number, then require the written scope below before comparing San Diego contractor bids.

Scope checks

  • - Space use: bedroom, office, ADU, gym, family room or rental suite, with egress, ceiling height and occupancy assumptions stated.
  • - Envelope work: slab condition, moisture control, wall and ceiling insulation, garage-door infill, windows, exterior finish and air sealing.
  • - Systems: electrical panel capacity, outlets, lighting, HVAC supply or mini-split, plumbing rough-in, smoke/CO alarms and ventilation.
  • - Closeout: building permit, inspection sequence, energy-code requirements, fire separation, driveway/parking impact and certificate or final approval.

Ask before deposit

  • - Is this priced as conditioned living space or only a finished storage room?
  • - How are insulation, HVAC, electrical, egress and fire separation handled?
  • - Who pulls permits and confirms whether the city treats the project as an ADU, bedroom or simple living-area conversion?

Common misses

  • - Ignoring slab moisture, garage-door infill and insulation while comparing finish-only quotes.
  • - No written HVAC, electrical or egress plan.
  • - Assuming the space can be advertised as a bedroom or rental unit without local approval.
