Garage Transformations That Add Real Value

Your garage may be the most underutilized space on your property. Whether it's filled with boxes or used as a makeshift storage room, that square footage has enormous potential. Michael Moser Development specializes in transforming garages into beautiful, functional spaces — from full ADU conversions to home offices, gyms, studios, and more.

We also build new garages and shops from the ground up. Our team can complete a standard garage structure in as little as one week — making it one of the fastest ways to add covered parking, storage, or workspace to your property.

Garage-to-ADU Conversions

Converting your garage into an ADU (Accessory Dwelling Unit) is one of the most cost-effective ways to add a rentable unit to your property. California law has made garage-to-ADU conversions easier than ever — in many cases, you can convert a garage to an ADU without replacing the lost parking space.

A typical garage ADU conversion includes:

Insulation and drywall
New flooring (concrete polish, LVP, or tile)
Kitchen or kitchenette installation
Bathroom addition or upgrade
Electrical panel upgrade and wiring
Plumbing connections
HVAC (mini-split or ducted)
New windows and exterior door
Permit coordination and final inspection

Frequently Asked Questions

How much does a garage conversion cost in Sacramento?

A basic garage-to-living-space conversion typically costs $30,000–$80,000. A full garage-to-ADU conversion with kitchen and bathroom can range from $60,000–$150,000 depending on scope and finishes. New garage construction typically starts around $30,000–$60,000 for a standard two-car garage.

Do I need to replace my parking space if I convert my garage to an ADU?

Under California state law, you generally do not need to replace the parking space when converting a garage to an ADU. This makes garage conversions one of the most accessible ADU options for Sacramento homeowners.

How long does a garage conversion take?

A basic garage conversion to a living space can be completed in 4–8 weeks. A full ADU conversion with kitchen and bathroom typically takes 8–16 weeks. New garage construction can be completed in as little as one week for a standard structure.

Can I convert my garage to a home office or gym instead of an ADU?

Absolutely. We convert garages to home offices, gyms, studios, game rooms, and more. These projects are often simpler and faster than full ADU conversions since they may not require kitchen or bathroom additions.
