Home Remodeling Contractor in Hidden Hills

Typical RnD Builders ranges: kitchens $35,000 to $150,000, bathrooms $25,000 to $85,000, interior remodels $75,000 to $250,000, garage conversions $140,000 to $200,000, new detached ADUs $220,000 to $350,000, room additions from $450 per square foot and custom homes from $650 per square foot. Architectural submittals and large-lot site work can add to a Hidden Hills project. Larger or more complex projects can run higher, and your written estimate confirms the exact price.

It depends on the scope. Kitchens are guaranteed within 28 days, bathrooms take about 3 weeks, garage conversions about 3 to 6 weeks for basic work, ADUs are finished within 3 months of the first day of construction, and a whole-home remodel runs 4 to 6 months. Design and permit approval come first on larger projects.

RnD Builders prepares the plans and submittals and manages corrections and inspections. In Hidden Hills the plans go to the Community Association's Architectural Committee for approval, and the City of Hidden Hills Building and Safety Department reviews them for code compliance, with applications and plan uploads handled through the city's online permit center.

Often yes. The City of Hidden Hills has an ADU program, and its preapproved-plan track covers detached, single-story units of 250 to 800 square feet up to 16 feet tall. Any ADU also needs Architectural Committee approval, and we confirm what fits your lot before design. New detached ADUs typically run $220,000 to $350,000, and your written estimate confirms the exact price.

Garage conversions typically run $140,000 to $200,000, and basic conversions take about 3 to 6 weeks of construction. Size, utilities and finishes change the number, so we confirm your exact price in a written estimate after we see the garage.

Yes for almost any exterior change. The Hidden Hills Community Association states that all modifications to the exterior of any home or building site require prior approval by its Architectural Committee, including remodeling, roofs, windows, doors, landscaping, driveways and retaining walls. We prepare the submittal for you.

No. The association states that the city's building inspector will not issue a building permit unless the plans show architectural approval, stamped and signed by two committee members. It also says the committee meets on the first and third Mondays of each month and that plans are due ten days before a meeting. We sequence the work around that schedule and keep you informed at each step, but we do not promise a total approval time.

Kitchens typically run $35,000 to $150,000, depending on size, layout changes, cabinetry and finishes, and a kitchen is guaranteed within 28 days. Larger kitchens and premium materials can run higher, and we confirm the exact price in a written estimate.

Yes. Room additions start at $450 per square foot, and we design the changes in 3D first so you can adjust them before construction. Lot size, setbacks and local floor area limits decide how much you can add, so we check them before design starts.

Yes. Whether you have a vacant lot or want to demolish and rebuild, we guide you through site evaluation, design, engineering, permits and construction. Custom homes start at $650 per square foot, and your written estimate confirms the price for your site.

Yes. We do not yet have a Hidden Hills project on our site, so this page features our Calabasas home addition and remodel, and we can arrange references during your estimate.

RnD Builders designs, permits and builds under one roof, with 3D renderings before construction, itemized written proposals and a Woodland Hills office serving Hidden Hills. Our office is at 21250 Califa St in Woodland Hills. Whoever you hire, check for a valid California license, a clear written contract and every required permit. RnD Builders is a licensed California general contractor, License #1081122, and you can verify it on the CSLB website. California requires a license for projects that need a permit or total $1,000 or more, so always ask any contractor for their license number.

We quote from the exact scope you approve and itemize it, so you can see where the money goes. Large lots can hide drainage, grading and utility conditions. Site conditions are checked on the first visit, and any change is agreed in writing before it is added, so the project stays in line with the budget agreed in your contract.

We serve Hidden Hills and the homes around it, from the gated streets to the properties along the trails. Ventura County is our main focus, including Thousand Oaks, Camarillo, Oxnard, Ventura, Simi Valley and Moorpark. We also serve across Los Angeles County, including Calabasas, Agoura Hills, Westlake Village, Woodland Hills and the South Bay. Ask us if you are not sure we cover your address.
