ADU Company in Mission Viejo, CA
Kitchen remodeling in Mission Viejo usually runs $35,000 to $85,000 depending on whether you’re refreshing a 1980s original or reworking the floor plan in a hillside home. Most of the kitchens we see in Mission Viejo were built between the late 1960s and early 1980s, which means closed-off layouts, fluorescent soffits, and cabinets that have been painted one too many times. We’re Home Base ADU Builders, and we’ve served Mission Viejo since 2016. Call (866) 403-9834 to talk through what’s possible on your street.
Why Mission Viejo Homes Are Different
Mission Viejo is a master-planned community, and that changes almost everything about remodeling. Nearly every home sits in a tract HOA, so kitchen and bathroom work is as much an HOA-approval job as a building-permit job. Many village associations impose design-review conditions, architectural standards, and notification requirements stricter than the state’s ADU law. Getting the HOA packet right is the real gate, and we handle that paper trail before you ever pick a faucet.
The housing stock is mostly 1960s through 1980s single-family tracts with tile roofs and stucco walls. Backyards are typically flat but shallow, which matters if you’re planning an ADU. Converting an attached garage or building on an existing patio is often far more practical than a detached new build. Inland south-Orange-County heat and frequent Santa Ana wind events mean any addition needs real cooling and fire-resistant detailing near the open-space and hillside edges. Lots slope up toward the ridgelines around Lake Mission Viejo and the greenbelts, so retaining walls and drainage plans, not the structure itself, are what push budgets up and trigger plan-check comments.
Our Main Mission Viejo Services
Two services dominate the calls we take from Mission Viejo homeowners: ADU construction and bathroom remodeling. Here’s how each works in this city.
ADU Builders in Mission Viejo
ADUs in Mission Viejo almost always start with the HOA packet. We work hands-on with six prefab manufacturers, including Abodu, Cover, Dvele, Mighty Buildings, Boxabl, and Plant Prefab, so we can match your lot and budget to the right build path rather than pushing one product. On shallow lots, a garage conversion or a unit on an existing patio footprint often clears design review faster than a detached build. From Tuff Shed conversions to architect-designed Dvele prefabs, we’ve built across the full spectrum.

Bathroom Remodeling in Mission Viejo
Most Mission Viejo bathrooms still have the original 1970s and 1980s fixtures: cultured marble vanities, fiberglass tub surrounds, and tile that has seen better decades. We remodel these spaces with an eye toward the same HOA constraints that touch every other job here. Whether you’re converting a tub to a walk-in shower or gutting a primary bath down to studs, the work runs through the same planning and approval process. Bathroom Remodeling in Mission Viejo covers cost ranges and what to expect on your specific project.

Kitchen Remodeling in Mission Viejo
Kitchen remodeling in Mission Viejo means working inside homes that are 40 to 55 years old, where the original footprint was built for a different kind of living. The kitchens are often closed off from the family room, short on counter space, and fighting the same stucco-and-tile logic as the rest of the house. We also work on homes near the hillside edges, where ventilation and fire-resistant materials around range hoods and exterior walls deserve more attention than they get in flatter parts of Orange County. This is our most requested service, and you can see our full approach on the Kitchen Remodeling hub.

What Mission Viejo Customers Say
"Unit came out great and the tenant is happy. The timeline ran long, largely because of how slow the city was on plan check, though a couple of the delays were scheduling on their end."
— Robert Hayes"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Colleen Pruitt"Knew the local setback and parking rules cold, which saved us from designing something that would never have been approved."
— Priya Mehta
