Key Cost Drivers for 2025

Land costs are the biggest variable. Site prep (grading, utilities) can add $50,000-$200,000+, especially on hillside lots in areas like Los Angeles.

2. Labor Costs (25-35% of construction)

Skilled labor shortages persist, keeping wages high, particularly in coastal California markets.

While some material prices have stabilized, they remain elevated. Lumber, concrete, and high-end finishes are significant cost factors.
