ADU Company in Mission Viejo, CA
Kitchen remodeling in Mission Viejo almost always means working inside a 1960s to 1980s tract home where the original footprint, plumbing rough-ins, and cabinet framing were set decades before anyone thought about open-concept layouts or oversized islands. We plan every Mission Viejo kitchen around two realities: the home’s original Mission Viejo Company construction methods, and inland south Orange County heat that punishes under-insulated exterior walls. Whether you’re adding an ADU with a full kitchen or reworking the one in your primary house, call (833) 589-8273 for a free estimate.
Why Mission Viejo Homes Are Different
Mission Viejo is a master-planned community built largely by the Mission Viejo Company between the 1960s and 1980s, and that history shapes every remodel and ADU project here. Homes across 92691 and 92692 sit on small, uniform lots with attached two-car garages, tile roofs, and stucco exteriors. The rear yard is usually the only flat, buildable area, so detached ADUs and garage conversions are the practical play. Matching the original stucco and tile palette matters because the HOA’s design-review committee can reject a rear ADU’s roof pitch or color if it does not echo the main house. The city’s post-2017 state ADU ordinances have to be reconciled with CC&Rs that predate ADU law entirely, which means every Mission Viejo project is a two-front approval: city permitting plus HOA architectural review. Inland heat adds another layer: west-facing walls bake in summer, attics need real insulation, and winter rains hit clay-heavy soils in short, intense bursts. We build every Mission Viejo job around those conditions from the first site visit.
Our Main Mission Viejo Services
Most Mission Viejo homeowners call us about one of two projects: building an ADU or remodeling a bathroom, and sometimes both in the same phase.
ADU Builders in Mission Viejo
Adding an ADU in Mission Viejo usually means a detached unit in the rear yard or a garage conversion, because lot sizes here do not leave much room elsewhere. We walk every project through the HOA architectural review and city permitting at the same time, and we compare prefab options from Mighty Buildings, Boxabl, Plant Prefab, and Tuff Shed against site-built construction so the recommendation fits your lot, timeline, and budget rather than a preferred vendor. Interior finish work stays in-house. See ADU Builders in Mission Viejo for the full breakdown.
Bathroom Remodeling in Mission Viejo
Original Mission Viejo bathrooms were built compact, often with the same floor plan repeated across entire tracts. We open them up where the framing allows, replace cast-iron and galvanized drain lines that have reached end of life, and correct ventilation issues that inland heat makes worse. The work is done under one contract with no handoff to a second contractor, which matters when the HOA asks for a single point of contact on exterior modifications.

Kitchen Remodeling in Mission Viejo
Kitchen remodeling in Mission Viejo typically costs $35,000 – $75,000 for a full renovation in these 1960s – 1980s tract homes, and the work usually takes three to six weeks once permits are in hand. Original Mission Viejo Company kitchens were designed for closed-off cooking, not open living, so most projects involve moving walls, reworking plumbing, and upgrading electrical panels that were sized for a different era. Inland heat means we also focus on ventilation, insulation, and appliance placement so the kitchen stays comfortable during the hottest summer months.
