If you’re looking for a cost-effective way to add living space to your property in San Luis Obispo County, a garage conversion to an ADU (Accessory Dwelling Unit) is one of the smartest investments you can make. At SLObispo Remodelers, we help homeowners transform unused garages into fully functional, code-compliant living spaces that add comfort, flexibility, and long-term value.

Why Convert Your Garage into an ADU?

Garage conversions are quickly becoming one of the most popular ADU options in SLO—and for good reason:

You already have the structure: No need to pour a new foundation or start from scratch.
Faster build time: Since the envelope of the building already exists, construction is significantly faster.
Lower cost: Typically cheaper than building a detached ADU from the ground up.
Rental potential: With SLO’s high demand for housing, it can generate excellent monthly income.
Multi-generational living: Give aging parents, adult children, or guests their own space.

What Makes a Garage Suitable for Conversion?

Most attached and detached garages can be converted to ADUs, but a few factors to consider include:

Square footage (ideally 300–600 sq ft or more)
Ceiling height and structural integrity
Access to utilities (water, sewer, power)
Zoning and setback rules for your area

We’ll assess all of this during your free consultation to make sure your project starts on solid ground.

What Goes Into the Conversion?

Every garage-to-ADU project is unique, but typically includes:

Insulation and drywall installation
Windows and doors for natural light and code compliance
Plumbing and electrical upgrades
Kitchenette and bathroom installation
Interior layout design to maximize space and function

We take care of everything—from structural evaluations and design to permits and final finishes.

Recent Project Spotlight

A homeowner in Paso Robles came to us with a detached 2-car garage they wanted to convert into a guesthouse. Within four months, we transformed the space into a fully equipped 1-bedroom ADU with a kitchenette, full bath, and custom finishes. They now rent it out as a long-term rental and enjoy passive income with minimal upkeep.
