Garage Conversion Cost Guide (2025)

Thinking about turning your garage into livable space? One of the first questions homeowners ask is: how much does a garage conversion cost in San Diego? At Fabrick Construction, we believe in transparency. This guide will help you understand real-world costs, what drives them, and how to budget wisely.

Typical Garage Conversion Costs in San Diego

Every garage is different, but most conversions in 2025 fall into these ranges:

  • Basic conversion (studio ADU): $80,000 – $120,000 Studio conversion (Self-performed): $90,000-140,000
  • Studio or 1-bedroom conversion (GC performed): $120,000-160,000
  • High-end finishes or complex utilities: $160,000+

What Drives the Cost of a Garage Conversion?

While every project is unique, ADUs typically range between $335–$425 per square foot for projects 600 sq. ft. or larger. Larger units often bring the cost per square foot down slightly, while smaller ones may run a bit higher.

Final pricing depends primarily on structural requirements, utility runs, and finish selections.

How to Save Money Without Cutting Corners
