Interior remodels generally run $75,000 to $250,000, kitchens $35,000 to $150,000, bathrooms $25,000 to $85,000, garage conversions $140,000 to $200,000 and detached ADUs $220,000 to $350,000, with additions from $450 per square foot and custom homes from $650 per square foot.

Plan on weeks for a single room and months for a whole home. Kitchens are guaranteed within 28 days, bathrooms run about 3 weeks, garage conversions about 3 to 6 weeks for basic work, ADUs within 3 months of construction start and whole-home remodels 4 to 6 months. Westchester's mild weather allows steady work through the year, so winter and summer schedules stay similar. We set a firm deadline once the design and permits are settled.

RnD Builders prepares the plans, submits them to the Los Angeles Department of Building and Safety, handles plan check corrections and coordinates the inspections. LADBS has a West Los Angeles office that serves the area, and we confirm the right pathway for your scope.

Not always. LADBS lists kitchen and bathroom remodels for residential buildings with no structural changes among its express permit projects. Anything that changes structure, such as removing a wall, goes through plan check, and we tell you which pathway applies at the consultation.

Generally yes. Los Angeles allows ADUs on lots zoned for single-family and multifamily use, and they must follow zoning, building and residential codes. We confirm feasibility for your lot, then handle design, permits and construction through final inspection.

Garage conversions generally run $140,000 to $200,000 and take about 3 to 6 weeks for basic work, and new detached ADUs run $220,000 to $350,000. Cost depends on size, site conditions and finishes, and your written estimate confirms the exact price.

Generally yes. Post-war homes here were frequently built as separate rooms, and opening them up usually means removing walls, which needs a structural review and often a new beam. We also assess the framing first, design the layout in 3D and handle the engineering and permits.

Kitchens generally 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 also run higher, and the written estimate confirms the exact price after we see your space.

It can. Parcels close to the airport can be subject to height limits set by the FAA and to added overlay rules, depending on location. We confirm your parcel's status upfront so that the design and the schedule account for any added review.

Yes. We also take on multi-story homes, expansive outdoor spaces and complex structural work. Custom homes start at $650 per square foot and generally take 11 to 20 months, and we handle lot evaluation, design, engineering, permits and construction. Your written estimate confirms the exact price.

Both work. Flat lots are usually more straightforward, while elevated or sloped lots bring grading, retaining walls and drainage planning. We evaluate the site early so the plan, the schedule and the estimate reflect the terrain.

RnD Builders designs, permits and builds under one roof, with 3D renderings before construction, itemized written proposals and a Woodland Hills office serving Westchester. Whoever you hire, check for a valid California license, a clear written contract and every required permit. Our California contractor license number is 1081122, and the CSLB website shows its status. In California, a license is required once a project needs a permit or reaches $1,000 in labor and materials, so verify any contractor before you hire.

Every estimate is itemized by scope and selection, and we walk the property before we price it. On 1940s and 1950s homes we check framing, plumbing and electrical before pricing. If the scope changes, you sign off in writing first, which keeps the project in line with the budget agreed in your contract.
