Fielding ADU Builders handles ADU construction, garage conversions, and room additions in Woodcrest, CA. Most of the homes here sit on larger Riverside County lots, which means most properties have room for a detached unit without fighting the property line. The soil is decomposed granite in many pockets, and that changes how we detail foundations and drainage. If you’re weighing options, call (361) 315-4177 and we’ll walk you through what fits your parcel.
Why Woodcrest Homes Are Different

Woodcrest is unincorporated Riverside County, not a city with its own municipal building department. Permits run through the county, and that adds a review step some homeowners don’t expect. Lots are typically half an acre to a full acre, so detached ADUs are usually the cleaner play than garage conversions here. The terrain rolls in places, and on sloped parcels we see more grading and retaining wall work before the foundation goes in. Summer heat is the other factor: units need real insulation and a properly sized mini-split, because a poorly cooled ADU in a Woodcrest August is unusable. We plan for that from the first site visit.
Housing stock leans toward single-story ranch homes built between the 1970s and early 2000s, many with attached garages. That gives us predictable wall framing and roof lines to tie into. Some neighborhoods, especially the larger equestrian-zoned pockets, have wells and septic systems, which changes where a unit can sit and how utilities connect. We check that early so the site plan doesn’t have to be redrawn.
Our Main Woodcrest Services
Woodcrest homeowners usually call us for one of three projects: more living space attached to the house, a garage turned into rentable or family space, or a stand-alone ADU in the backyard. Each has its own page with pricing and detail specific to this area.
Room Addition Contractor in Woodcrest
A room addition in Woodcrest usually means extending off the back or side of a ranch home, tying into the existing roofline, and pouring new foundation on granite soil. The county reviews structural plans, so the design has to be right before we break ground. We price the job in writing first, including the engineering, the permit set, and the finish work.

Garage Conversion Contractor in Woodcrest
Garage conversions in Woodcrest mean converting an existing attached garage into conditioned living space. The slab is usually already there, which keeps foundation costs down. We re-insulate the walls, upgrade the electrical panel if the house needs it, and handle the county inspection process from start to finish. Garage Conversion Contractor in Woodcrest

Brands We Service in Woodcrest
We install and finish units from Abodu, Cover, and Dvele, and we work with conventional materials like James Hardie siding where a stick-built unit is the better fit. Parts and panels ship to our Inland Empire yard and roll out to Woodcrest on our own trucks, so there’s no long wait for a distributor to restock. See our brands for what we currently install.

FAQs About ADU Company in Woodcrest

Site visits typically happen within a few days of your call. County plan review in Riverside County usually runs six to ten weeks depending on their current volume. After that, construction on a prefab unit from Abodu or Cover moves faster than a stick-built unit, but both get the same written guarantee. Call (361) 315-4177 to get on the schedule for a free estimate.

No. The price you approve in writing is the number on the final invoice. The only exception is if you change the scope – adding square footage, changing finishes, or upgrading the panel mid-project.
