How Much Does a Full Home Remodel Cost in California?
Full home remodels in San Diego and California in 2026 run $100-$400+ per square foot of living area. The range is huge because 'full home remodel' covers everything from a cosmetic facelift to down-to-the-studs reconstruction. Most homeowners' first quote arrives 30-50% lower than the final number — usually because the original scope didn't include systems work, permit timelines, or owner-driven scope creep.
Three Tiers of Full Home Remodel
Pick the tier honestly based on your house's condition and your goals:
- Cosmetic refresh ($75-150/sqft): paint, flooring, lighting, fixture swaps, minor kitchen/bath updates. No structural or systems work. 2-4 month timeline
- Mid-range gut ($150-275/sqft): full kitchen and baths, new flooring throughout, updated lighting and electrical, possible HVAC. Walls stay. 5-9 months
- Down-to-studs / structural ($275-450+/sqft): walls open, new electrical, plumbing, HVAC, possible reconfiguration of layout, full kitchen and baths, all finishes. 10-18 months
Where Full-Home Remodels Always Go Over
Predictable cost overruns:
- Hidden conditions discovered during demo: galvanized plumbing, knob-and-tube electrical, dry rot, mold, foundation cracks (+$15-80K)
- City permit requirements once a single permit is pulled: Title 24, low-flow fixtures, hardwiring smoke detectors, GFCI everywhere (+$5-25K)
- Owner change orders mid-build: 'while you're here, can you also...' usually adds 10-25% over contract
- Material upgrades during selection: original finish budget vs final shopping is typically 30-60% higher
- Schedule extension cost: temporary housing for 4 extra months at $2,500/mo = $10K unbudgeted
Sequencing That Saves Money
Order matters when you remodel an entire house:
- Permits and structural decisions first — anything later requires re-work
- Roof, exterior, windows before interior — leaks during interior work waste materials
- Rough plumbing, electrical, HVAC before drywall
- Floors near the end so they don't get damaged by other trades
- Kitchen cabinets ordered 12-16 weeks ahead of installation — they're the longest lead
- Punch list and final paint last — touch-ups always needed after every trade
