ADU Company in Rancho Santa Margarita, CA

Kitchen remodeling in Rancho Santa Margarita means working with 1980s and 1990s Mediterranean-style tract homes where original layouts, aging cabinets, and inefficient appliances no longer match how families live today. The foothill climate, with hot inland summers and occasional Santa Ana winds, also means ventilation and cooling upgrades matter as much as the aesthetic refresh. Harvest ADU Builders handles the full kitchen remodel, from layout changes to finish work, and we pair it with ADU construction knowledge most kitchen contractors in Rancho Santa Margarita simply don’t have. Call (866) 538-0916 for a free estimate on your kitchen project.

Why Rancho Santa Margarita Homes Are Different

Rancho Santa Margarita is a master-planned community built primarily in the 1980s and 1990s, which means most kitchens sit inside stucco tract homes with tile roofs and attached two-car garages. The original floor plans were designed for a different era: small, enclosed kitchens with limited counter space, fluorescent lighting, and cabinets that have now seen three decades of use. Many homes in the foothills of the Santa Ana Mountains also sit on sloped lots, which affects how we run plumbing, electrical, and venting during a remodel. HOA architectural review and CC&Rs add another layer: exterior changes, including kitchen venting or window modifications, often need design approval from the association before the city permit moves forward. That combination of older housing stock, hillside terrain, and HOA oversight shapes every kitchen remodel we do in Rancho Santa Margarita.

Our Main Rancho Santa Margarita Services

Rancho Santa Margarita homeowners reach out to us most often for two projects: building or installing an ADU, and remodeling the bathrooms that came with these 1980s and 1990s homes. Both require working within the city’s HOA design expectations and the physical realities of these foothill lots.

ADU Builders in Rancho Santa Margarita

Adding an ADU in Rancho Santa Margarita means navigating both California state ADU law and the city’s layered HOA design review. Many original tract homes sit on small lots with tight setbacks, and hillside placements force careful decisions about foundation type and unit size. We help homeowners here match a prefab unit from brands like Dvele, Mighty Buildings, or Boxabl to their specific lot constraints, or we manage a site-built ADU where the terrain calls for it. ADU Builders in Rancho Santa Margarita covers the full process, from design approval to move-in ready.

Bathroom Remodeling in Rancho Santa Margarita

The bathrooms in Rancho Santa Margarita’s 1980s and 1990s homes were built with fiberglass tub surrounds, dated tile, and limited storage, and many now show water damage around the tub and shower areas. Hot, dry summers put extra strain on bathroom ventilation, so we plan exhaust and moisture control into every remodel we do here. Our bathroom work pairs naturally with ADU construction: when we build a detached unit, we finish the bathroom in-house so the entire project stays under one contractor.

Kitchen Remodeling in Rancho Santa Margarita

Kitchen remodeling in Rancho Santa Margarita typically runs $35,000 to $85,000 for a full gut-and-replace, with basic refacing or countertop swaps landing between $15,000 and $25,000. These numbers reflect what we see in the city’s 1980s and 1990s tract homes, where original kitchens are small, enclosed, and often carry three decades of wear across cabinets, counters, and flooring. Rancho Santa Margarita homeowners also deal with HOA design review when a remodel touches exterior elements like windows, venting, or the roofline. Our approach is simple: we match the right materials and layout to the home, handle the permits and HOA paperwork, and finish the entire kitchen under one roof. If you’re weighing an ADU alongside a kitchen remodel, we can sequence both projects so the ADU’s kitchen and the main home’s kitchen get built by the same crew.

— Heather Rhodes

"The kitchenette layout he suggested made better use of the space than the one on our original sketch."

— Marco Reyes

"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."
