Why Garnet Homes Are Different

The living room inside a new ADU

Garnet sits in a part of Riverside County where lot sizes vary more than people expect. Some parcels are flat and straightforward; others slope enough that grading becomes a real line item before a foundation ever gets poured. We’ve worked on Garnet properties where the difference between a simple slab and a stepped foundation changed the project cost by several thousand dollars, so we always check the terrain before quoting anything.

Housing stock here leans older, which means electrical panels and water lines sometimes need upgrading before an ADU can tie in. That’s not a surprise cost if it’s identified early; it’s only a surprise if the contractor skips the site visit or quotes blind. The other recurring factor in Garnet is setback variance: the city’s written permission to build closer to the property line than the standard rule allows. Some Garnet lots need it, some don’t, and the application adds time. We factor it in from the start so the schedule holds.

Our Main Garnet Services

Most Garnet homeowners who call us are weighing one of three projects. Each has its own page where you’ll find pricing, timelines, and the specific way we handle that job in Garnet.

Room Addition Contractor in Garnet

A room addition in Garnet usually means extending the footprint of the main house, which brings grading, foundation, and roofline work into play. We price it with a written line item for every phase so the number you approve is the number on the final invoice. Room Addition Contractor in Garnet

Garage Conversion Contractor in Garnet

Converting an existing garage is often the fastest path to added living space in Garnet because the structure and slab are already there. The work shifts to insulation, drywall, electrical, and bringing the space up to code as habitable square footage. Garage Conversion Contractor in Garnet

Pricing for ADU Company in Garnet, CA

Service Typical range in Garnet
Garage conversion $80,000 – $140,000 before permit fees
Detached ADU (modular/prefab) $180,000 – $280,000
Detached ADU (conventional build) $250,000 – $380,000
Room addition (300 – 600 sq ft) $90,000 – $180,000

Setback variance application $1,500 – $4,000 in city and consultant fees
Utility trenching and hookups $5,000 – $18,000

What pushes a Garnet price toward the top of these ranges is usually site work: slope, soil, and how far utilities have to run from the street. We hand you a written price before any work starts, so the figure you approve on day one is the figure on the final invoice.
