ADU
Detached backyard units, attached units, and conversions. These are complete homes that can be rented.

Home and room additions
Primary suites, family rooms, and extra bedrooms that blend with your existing home.

3D Design Rendering
Walk through your project virtually before construction starts, so you can adjust the plan early.

Guest quarters aka Granny Flats
A smaller space for visiting family and guests. It has no full kitchen and can’t be rented.

Second-story additions
We add living space above your existing home for new bedrooms, a primary suite, or a family room without losing yard space.

Garage conversions
We convert attached, detached, and integral garages into a backyard rental, a granny flat, a home office, or a gym, theater, or game room.

Kitchen extensions and remodels
We expand or fully remodel your kitchen as part of an addition or on its own.
Step 1
Get Expert Guidance
Our designer measures your home and creates full-color 3D renderings, plans, and elevations. You can take a virtual walk-through of the design before we lift a hammer.
Step 2
Win the Permit
ADU permitting varies by jurisdiction. Ritz has been building in San Diego County since 1965 and knows the rules. We research your property before design, stay current on State, County, and city regulations, then submit your permit package and follow it until the permit is issued.
Step 3
Build the ADU
During construction, our field team takes over. They’ve worked together for years, and you’ll see it in their professionalism and skill. You can feel confident your home is in experienced hands.
Some decisions will still come up during the build, and the Ritz office staff is available to help.
