Estimate your project with the California cost calculatorSan Diego is a high-cost coastal market where new residential construction typically runs about $250 to $400 per square foot, with custom and coastal work pushing well past $450.
Coastal exposure, seismic requirements and California's energy code all move the number, and Coastal Commission review adds time on many sites. A defensible San Diego bid starts from local rates and real site conditions — a national average understates almost every line.

What drives cost in San Diego
Seismic engineering & foundations
California seismic code requires engineered foundations and lateral systems; canyon and hillside lots common in San Diego add retaining and foundation cost.
Title 24 energy code & solar mandate
High-performance envelopes, efficient HVAC and mandatory solar on new homes add cost that a national average never accounts for.
Coastal Commission & permitting
Projects in the coastal zone can require California Coastal Commission review, adding time and cost that vary significantly by parcel.
Site prep & sales tax
Grading, drainage and utility work vary by lot, and combined sales tax of roughly 7.75% applies to all materials.
