1. California Requirements

Many California garages store more junk than cars. Converting that space to an ADU provides housing, generates income, and increases property value.

1. California Requirements

Studio Apartment Conversions

One-car garages (200-250 sq ft) convert to efficient studio apartments with Murphy beds, compact kitchens, and full bathrooms. Rental income: $1,200-2,000/month in most SoCal areas.

One-Bedroom Conversions

Two-car garages (400-500 sq ft) allow separate bedroom, living, kitchen, and bathroom spaces. These larger units command $1,800-3,000/month in rental markets.

Design Considerations

Ceiling height, natural light, ventilation, and parking replacement are key considerations. We design conversions that feel like intentional living spaces, not converted garages.

California Requirements

ADUs must meet building code for egress, ventilation, plumbing, and electrical. California has streamlined permitting, but proper design and permitting are still required.

Final Thoughts

Garage conversions offer the fastest, most affordable path to adding an ADU. The key is thoughtful design that creates comfortable, code-compliant living space.

Frequently Asked Questions

Do I have to replace lost parking?

California law no longer requires parking replacement for ADU conversions in most cases, making garage conversions more feasible.

How long does conversion take?

Typical garage conversions take 3-5 months from permit to completion. Permitting usually takes 4-8 weeks.
