Modern bathroom renovations in LA and San Diego average $20,000–$45,000 for mid-range projects, with labor accounting for 40–60% of costs. New 2025 Title 24 energy code (effective January 2026) requires enhanced ventilation for heat pumps and higher-efficiency fixtures, adding 5–10% to your project budget. Permits typically take 2–4 weeks in San Diego, 3–8 weeks in LA.

LA kitchens in 2026 must comply with Title 24 lighting rules, efficient ducting standards, and fresh-air or recirculating ventilation pathways. Slab foundations significantly impact layout flexibility, especially for island ventilation, sink drain placement, and electrical routing. Typical HVAC-related upgrades add $4k to $20k to a kitchen remodel budget, depending on duct length, roof access, and existing electrical capacity.
