Home Remodeling Contractor in Northridge

Northridge is part of the City of Los Angeles, so the Los Angeles Department of Building and Safety reviews plans, issues permits and inspects the work. RnD Builders also prepares the plans and submittals and manages corrections and inspections.

Yes. LADBS runs a Standard Plan Program that pre-approves ADU plans, which shortens plan check when the plan fits your site. We also help you choose between a pre-approved plan and a custom design.

Not within a half-mile walk of public transit, and covered parking removed to build an ADU does not need to be replaced. We check your address against the City’s rules before we design.

Yes. We check foundations, framing and utilities when walls are open and plan any needed upgrades into the scope and the estimate, so there are fewer surprises once work begins.

Often. Wall removals are one of the most common requests in older Valley homes, and our West Hills project turned a 1960s house into a modern home with major wall removals. We confirm what is structural before we price.

We serve Northridge Estates, Northridge East and Northridge West, plus Porter Ranch, Chatsworth, West Hills and the rest of the San Fernando Valley. Ask us if you are not sure we cover your address.

Northridge homeowners usually ask about three numbers first: kitchens at $35,000 to $150,000, bathrooms at $25,000 to $85,000 and interior remodels at $75,000 to $250,000. Beyond those, garage conversions run $140,000 to $200,000, detached ADUs $220,000 to $350,000, additions start at $450 per square foot and custom homes at $650. Site conditions can also change a project. Your estimate itemizes every cost element, and larger or more complex projects can also run higher.

Timelines follow the work. A kitchen is guaranteed within 28 days, a bathroom takes about 3 weeks and a basic garage conversion 3 to 6 weeks, while a detached ADU takes up to 3 months from the first day of construction and a whole-home remodel 4 to 6 months. We set realistic timelines at the start.

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 we confirm the exact price in a written estimate after we see your space.

New detached ADUs generally run $220,000 to $350,000, and garage conversions $140,000 to $200,000, depending on size, site conditions and finishes.

Yes. Whether you have a vacant lot or want to demolish and rebuild, we guide you through site evaluation, architectural design, structural engineering, permits and construction. Custom homes start at $650 per square foot and generally take 11 to 20 months.

We price from what we can see and verify on the first visit, and we list it line by line. On older homes we check framing, plumbing and electrical before pricing. Any change is agreed in writing before work on it begins, so the project stays in line with the budget agreed in your contract.
