Space is tight in Fountain Valley. Most lots here were platted back in the 1960s, and squeezing a functional ADU or tiny home onto one takes real planning experience, not guesswork. We’ve built tiny homes on wheels, park model homes, ADUs, and full remodels across Fountain Valley and the surrounding Orange County cities for years now, and we’ve learned exactly what this city’s lots, soil, and permitting offices require.
Whether you need a rentable ADU in your backyard, a whole-home remodel, or a tiny home on wheels for a family member, we handle it as licensed custom home builders and remodelers. Give us a call at (213) 320-4079 and let’s talk through what’s possible on your property.

We work with a lot of different homeowners around Fountain Valley, and the reasons people call us vary quite a bit. Some folks in Greenbrook and Fountain Valley Meadows want a backyard ADU for aging parents who need to be close but still independent. Others near the Talbert-Brookhurst corridor are looking at a tiny home on wheels for a college-age kid, something that can move if life changes down the road.
We also hear from landlords who want to add a rentable unit for extra income, given how strong the rental market is this close to Huntington Beach and Costa Mesa. Then there are the growing families in older Fountain Valley tract homes who’ve simply outgrown their kitchen or need a second bathroom. Whatever brings you to us, we’ve probably built something similar nearby.

We design and build custom THOWs on certified trailers, built to towable standards while still feeling like a real home inside. Most Fountain Valley clients use these for family housing or as a mortgage-free starter option. Expect a build timeline of 3-5 months depending on finishes and layout complexity.
Park models give you more square footage than a THOW while staying within RV-park and some residential zoning categories. We build these to RVIA standards, which matters a lot if you're placing one in a park community around Orange County. They're a solid option for retirees looking to downsize without sacrificing comfort.
This is where we spend most of our time in Fountain Valley. We design ADUs that actually fit the city's setback and lot coverage rules, which trip up a lot of first-time ADU owners. We handle everything from the site survey through final inspection.
Prefab construction lets us cut build time significantly since major components arrive site-ready. We still customize floor plans and finishes to match what you actually want, not a one-size-fits-all box. This works particularly well for Fountain Valley's smaller infill lots.
For clients doing a full rebuild or building on a rare vacant lot, we design and construct from the ground up. Every custom home gets engineered for our local soil conditions near the Santa Ana River floodplain. We manage the entire process, from architectural plans through final certificate of occupancy.
Comfortable, private space for family members. Our granny flat builds keep loved ones close and independent.
Full remodels let us update the electrical, plumbing, and structural bones of older Fountain Valley homes built in the 60s and 70s. We've upgraded a lot of original panels here to support new appliances and ADU electrical loads at the same time. Timelines usually run 3-6 months depending on scope.
Adding square footage instead of moving is popular here given how tight the resale market is. We handle room additions, second-story pop-tops, and garage conversions with full structural engineering. Most additions take 8-14 weeks once permits clear.
We rebuild bathrooms with attention to moisture control, which matters more here than people realize given the marine layer humidity. Typical projects run 3-4 weeks and include new plumbing, tile, and ventilation upgrades. We can match your home's original style or go completely modern.
Kitchen projects usually involve reworking layouts in these older Fountain Valley floor plans, which tend to have closed-off, cramped kitchens by today's standards. We handle cabinetry, counters, plumbing relocation, and electrical in one coordinated project. Most kitchens take 4-6 weeks start to finish.

A lot of Fountain Valley's R-1 zoned lots sit under 7,000 square feet, which limits where an ADU or addition can legally go. We map setback requirements during our first site visit so you know exactly what's buildable before we draw a single plan.
Parts of Fountain Valley near the Santa Ana River have a higher water table and clay-heavy soil. We've had to adjust foundation designs more than once here to account for this, and we always recommend a soil test before finalizing engineering on larger builds.
Several Fountain Valley tracts have active HOAs with their own design review process on top of city permitting. We've been through this enough times to know which HOAs move fast and which ones need extra lead time built into your schedule.
Homes built during Fountain Valley's big growth years in the 60s and 70s often have electrical panels that can't support a new ADU or major addition without an upgrade. We check this early so it doesn't stall your project halfway through construction.
We start with a walk of your property to check lot lines, existing utilities, and any HOA restrictions specific to your Fountain Valley neighborhood. You’ll leave this meeting with a realistic sense of what fits and what it’ll cost.
We prepare and submit plans to the City of Fountain Valley, handle engineering for soil and structural requirements, and manage the back-and-forth with plan checkers. This step usually takes 6-10 weeks depending on project complexity.
Our crews build to the approved plans with scheduled inspection checkpoints along the way. We keep you updated regularly instead of going dark for weeks at a time, something we know frustrates homeowners with other builders.
Once the city signs off, we walk the finished space with you, address any punch-list items, and hand over your warranty documentation. We stay reachable after the job’s done, not just until the final check clears.

Most Fountain Valley ADUs take 6-10 months total, including permitting time. Permitting alone often takes 6-10 weeks, with construction following at 4-6 months depending on size.
Park models are built to RVIA standards and are generally larger, often placed in RV parks or on qualifying land. THOWs are smaller, fully mobile, and built to towable trailer specifications.
Not always, particularly in Fountain Valley's older tracts from the 60s and 70s. We check your panel capacity during the site visit and include any needed upgrades in your quote upfront.
