Local know-how

Home Remodeling in Westlake Village: Local Know-How

Four things that shape a Westlake Village remodel.

  • HOA Architectural Review

    Westlake Village expects a higher standard, and remodels here need to clear HOA architectural committees that take design review seriously, from the lake-adjacent communities to North Ranch and First Neighborhood.

    We prepare the complete submittal, with drawings, materials and colors, and present to the committee when needed.

  • Which Westlake Village?

    The city of Westlake Village sits in Los Angeles County, while the Westlake Village section of Thousand Oaks sits in Ventura County, so the same mailing address can mean a different permitting office.

    We confirm jurisdiction on day one so your plans go to the right agency.

  • Hillside and View Lots

    Sloped and view lots are common here, and lots in the Hillside Management Area carry added standards for site planning, views and grading.

    We handle grading assessments, foundation engineering and structural planning for challenging terrain.

  • Homes From the 1970s to 1990s

    A lot of Westlake Village homes were built in the 1970s through the 1990s. Many are ready for new layouts, kitchens and primary baths.

    We check conditions behind walls and floors before pricing so there are fewer surprises.

We recently completed a full kitchen remodel with R&D Builders and are very happy with both the experience and the finished product.

Roi, one of the owners, was our primary point of contact. He’s personable, charismatic, and genuinely easy to work with. He has high standards, pays attention to the details, and clearly cares about making sure his customers get exactly what they envisioned.

R&D coordinated all aspects of the remodel, including demolition, framing, drywall, insulation, plumbing, electrical, flooring, countertops, and stucco work. The drywall and countertop teams were particularly excellent, and the quality of the finished work shows.

What impressed us most was how smoothly Roi kept everything moving. The different trades flowed from one to the next without long delays, and the entire project was completed in about a month. He was also flexible when we changed the scope of work and consistently followed through to make sure everything was done right.

Competitive pricing, excellent workmanship, great communication, and a genuinely positive experience from start to finish. We would happily recommend Roi and R&D Builders!
Response from RnD Builders IncDave! Thank you so much for the kind words and for trusting us with your home. It was a pleasure working with you, and we’re so happy you’re enjoying the finished project!

I connected with Roi via Reddit on a post I had regarding a construction question. I live in Sacramento and Roo lives in LA. I sent him my building plans and we hopped on a call. Roy took the time to speak to me about my plans, go over all of his concerns and details about our project. He did this out of his own time and willingness just to be a helping hand on a project he has 0 financial incentive on. we spoke for over an hour on the phone and provided his professional opinion about my ADU remodel and inspection items I had concerns with. Roi was extremely detailed and went through various scenarios to ensure our course of action and engineering recommendations made sense before spending additional money on our project. I likely will never work with him as I’m on the opposite end of the state but purely based off of my convo with him, if I was in LA I’d love to get the chance to.

Larger or more complex projects can run higher, while your written estimate confirms the exact price.

How long does an RnD Builders project take in Westlake Village?

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, while a whole-home remodel runs 4 to 6 months. We set a deadline based on the details of your project, and design, HOA review and permit approval come first on larger work.

Does RnD Builders work with Westlake Village HOAs?

Yes, regularly. We prepare the complete architectural review submittal, such as drawings, materials and colors, and present to the committee when needed. Each community sets its own standards, so tell us your community and we plan the package around its process.

My address says Westlake Village. Which agency permits it?

It depends on which side of the county line you are on. Addresses in the incorporated City of Westlake Village are in Los Angeles County, and addresses in the Westlake Village section of Thousand Oaks are in Ventura County and are handled by the City of Thousand Oaks. We verify jurisdiction before design starts so plans go to the right office.

Who handles permits and plan check for remodeling in Westlake Village?

RnD Builders prepares the plans, submittals and corrections and manages the inspections. The City of Westlake Village contracts with Los Angeles County for building and safety services, and online applications go through the county's EPIC-LA system, while the city's Planning Division handles zoning approvals.

Do I need a permit to work near oak trees in Westlake Village?

Possibly. In addition, the city protects oak trees with a trunk diameter greater than 4 inches measured at 4 feet 6 inches above the ground, and altering or removing one requires a Protected Tree Permit. We check your lot for protected trees during the first visit and plan the design, access and equipment around them.

Can RnD Builders build on sloped or hillside lots in Westlake Village?

Yes. Sloped and view lots are common here. We also handle grading assessments, foundation engineering and structural planning for challenging terrain. Lots in the city's Hillside Management Area also follow added standards for site planning, view preservation and grading, which we review before design begins.

Can I build an ADU or convert a garage in Westlake Village?

Generally yes. In addition, the city reviews ADUs administratively through its Zoning Clearance process. A garage conversion can be a faster route to extra living space. Size, setbacks and HOA rules depend on your lot, so we confirm what fits your property at the consultation.

What projects does RnD Builders build most in Westlake Village?

Luxury kitchen renovations, spa-level primary baths, whole-home refreshes of 1970s to 1990s construction, garage conversions and outdoor living spaces built for entertaining.

What does a kitchen or bathroom remodel cost in Westlake Village?

Kitchen remodels in Westlake Village generally run $35,000 to $150,000. Bathrooms $25,000 to $85,000, depending on size, layout changes, cabinetry and finishes. Larger kitchens and premium materials can also run higher. Detailed proposals follow your consultation, while your written estimate confirms the exact price.

Does RnD Builders build custom homes in Westlake Village?

Yes. Custom homes start at $650 per square foot, and hillside lots, high-end finish packages and complex site work add to the investment. We handle design, engineering, city or county approvals and construction, and a custom home generally takes 11 to 20 months. Larger or more complex projects can run higher, while your written estimate confirms the exact price.

Why hire RnD Builders as your home remodeling contractor in Westlake Village?

RnD Builders designs, permits and builds under one roof, with itemized written proposals, verified reviews and a Woodland Hills office a short drive from Westlake Village. Whoever you hire, check for a valid California license, a clear written contract and every required permit. RnD Builders holds California contractor license #1081122, which you can look up on the CSLB website. A license is required in California for work that needs a permit or totals $1,000 or more, so ask any contractor for their number before you sign.

How does RnD Builders prevent surprise costs in Westlake Village?

Your written estimate lists the scope and each selection. We check the site on the first visit, such as slope, soil and existing conditions on view lots. If something changes, you approve it in writing before it is added, so the project stays in line with the budget agreed in your contract.

Which Westlake Village communities and nearby cities does RnD Builders serve?

We serve the lake-adjacent communities, North Ranch and First Neighborhood in Westlake Village, the Westlake Village section of Thousand Oaks and the nearby Conejo Valley.
