What's Driving Costs in 2025
Labor Costs
California labor costs are among the highest in the nation, driven by:
- Prevailing wage requirements on public projects
- Skilled labor shortage
- High cost of living requiring higher wages
- Strong demand for construction workers
Expect labor to represent 40-50% of your project cost.
Material Costs
Material prices have largely stabilized after the 2021-2022 spikes:
- Lumber: Down from peaks, but still 30% above 2019 levels
- Concrete: Relatively stable with modest annual increases
- Steel: Stabilized but subject to tariff uncertainties
- Appliances: Back to normal availability and pricing
- Cabinets: Lead times improved to 4-6 weeks for stock/semi-custom
Permit and Fee Costs
California permit fees vary widely by jurisdiction but typically add 5-15% to project costs:
- Building permit fees
- Plan check fees
- School impact fees (for additions and new construction)
- Utility connection fees
- Traffic mitigation fees (commercial)
Regional Variations
Within our service areas, costs vary by location:
- San Diego coastal communities: 10-20% premium
- San Diego inland: Base-level pricing
- Ventura County: Similar to SD inland, slightly lower
- SLO County: 5-10% below San Diego averages
How to Budget Your 2025 Project
- Get multiple bids — Prices can vary 20-30% between contractors
- Add 10-15% contingency — Unexpected conditions happen
- Lock in material prices early — Order cabinets, fixtures, and specialty items when designs are final
- Consider phasing — Breaking large projects into phases can spread costs
- Be realistic about scope — Wish lists often exceed budgets
