ADU Company in Mission Viejo, CA
Kitchen remodeling in Mission Viejo usually means working inside a 1970s or early 1980s tract home where the original layout, slab, and electrical panel were never designed for today’s appliances or the way families actually cook. Sunstone ADU Builders handles ADU construction and interior kitchen and bath finishing under one roof, so whether you’re adding a rental-ready unit or remodeling the primary house, you’re not coordinating separate crews. Call (855) 949-1913 to talk through your project and get a free estimate.
Why Mission Viejo Homes Are Different
Mission Viejo is one of the original master-planned communities of South Orange County, built out almost entirely between 1968 and the late 1980s. Nearly every kitchen remodel here happens inside a tract home whose slab, wall framing, and service panel are now 40 to 50 years old. We regularly see 100-amp panels that need upgrading before a modern induction range and double oven can go in, and original single-story plans with kitchens that open onto family rooms through load-bearing walls that require beam work to remove.
The climate matters too. Mission Viejo sits inland enough to get real summer heat and the dry Santa Ana wind events each fall. That pushes many owners toward ventilation that actually moves air, insulation in exterior kitchen walls, and appliance choices that don’t turn the room into a heat trap by August. And because a large share of the city’s tracts sit under recorded CC&Rs and architectural review boards, interior work like a kitchen remodel is usually simpler than exterior work, but any change to windows, venting, or rooflines can still trigger HOA submittal requirements alongside city permits. The HOA-plus-city double approval is a Mission Viejo reality that doesn’t exist in neighboring Lake Forest or Laguna Niguel to the same degree.
Our Main Mission Viejo Services
Homeowners in Mission Viejo call us most often for two projects: adding an ADU to a tract lot that wasn’t designed for one, and remodeling bathrooms in homes that are decades past their original finishes. Here’s what each involves in this city.
ADU Builders in Mission Viejo
Most Mission Viejo ADUs are second-generation builds on lots whose setbacks, shallow rear yards, and HOA architectural rules were set when the tracts were first drawn in the late 1960s through the 1980s. That means many projects end up as garage conversions or attached junior ADUs rather than detached units in the backyard. We evaluate the slab, the panel, the drainage, and the CC&Rs before recommending prefab or stick-built, and we pull the permits ourselves. Read more about how we approach these jobs at ADU Builders in Mission Viejo.
Bathroom Remodeling in Mission Viejo
Bathrooms in Mission Viejo’s original tract homes run small, and the old tile-over-drywall showers and cast-iron drains are at the end of their service life in many houses. We rebuild them as waterproofed, curbless or low-curb showers that work for aging-in-place and rental-ready ADUs alike. Most of these projects stay inside the existing footprint, which keeps HOA involvement to a minimum. See Bathroom Remodeling in Mission Viejo for scope and typical costs.

Kitchen Remodeling in Mission Viejo
Kitchen remodeling in Mission Viejo is usually about fixing a layout that made sense in 1978 and doesn’t anymore. The original Mission Viejo Company tract homes were built with compact galley or L-shaped kitchens, single ovens, and no real landing space beside the cooktop. Homeowners here are reworking those rooms for double ovens, islands, and open sightlines to the family room, and doing it inside walls and slabs that demand careful structural and electrical work. We complete the entire kitchen scope in-house, from demolition through tile and millwork, which means one contract and one crew from start to finish. For the full overview of our process and standards, see our Kitchen Remodeling page.
Full Kitchen Renovation
Signs you need it
The layout fights you daily: no prep space beside the range, a peninsula that blocks the room, or cabinets that don’t hold what a modern kitchen needs to store.
What it costs in Mission Viejo
A full Mission Viejo kitchen renovation typically runs $60,000 to $90,000 for a 1970s-80s tract home, depending on cabinet grade, structural work, and appliance package.
How we do it
We demo to studs, reframe for the new layout including any beam work where walls come out, run new electrical and plumbing, then install cabinets, counters, backsplash, flooring, and appliances as one scope.
Kitchen Cabinet Refacing
Signs you need it
Your cabinet boxes are solid but the doors are worn, dated, or the hinges are failing, and the layout still works for the way you cook.
What it costs in Mission Viejo
Cabinet refacing in Mission Viejo generally runs $20,000 to $35,000, which covers new doors, drawer fronts, veneers, and hardware without touching the basic footprint.
How we do it
We measure and remove existing doors and fronts, apply matched veneer to the cabinet boxes, install new doors and drawer faces, and swap hardware, leaving the counters and layout in place.

FAQs About ADU Company in Mission Viejo
In most Mission Viejo tracts, yes. The city issues the ADU permit, but recorded CC&Rs and an architectural review board often require a separate submittal packet for any exterior change. We prepare and manage both approvals so the project doesn’t stall at either counter.
Once the design and permit documents are approved, we typically schedule start dates within two to four weeks depending on current workload. Kitchen and bath remodels usually begin sooner than full ADU builds because fewer approvals are involved.
We cover all of Mission Viejo including the 92690, 92691, and 92692 ZIP codes, plus nearby cities such as Lake Forest, Laguna Hills, Rancho Santa Margarita, and Coto De Caza. Any project in South Orange County is worth a conversation to see if the drive and the scope make sense.
