Local know-how

Woodland Hills Local Know-How

Four things that shape a Woodland Hills remodel.

  • LADBS Permits

    Permits run through the Los Angeles Department of Building and Safety. Some projects, such as kitchen and bathroom remodels with no structural changes, qualify for express permits, while additions and ADUs go through plan check.

    We manage the entire process: plans, plan check corrections and inspections.

  • Hillside Homes Near Mulholland

    Newer hillside homes near Mulholland come with slope, grading and foundation questions, and some sit under the Mulholland Scenic Parkway Specific Plan or the Baseline Hillside Ordinance.

    We review which rules apply to your parcel before design, so the plan and the estimate reflect the hillside.

  • Mid-Century Ranch Homes

    A 1950s ranch south of the Boulevard remodels differently than a hillside home. Compartmentalized floor plans, original kitchens and dated baths are the usual starting points.

    We design open layouts that fit how families live now and check conditions behind walls before we price.

  • ADUs and Garage Conversions

    Many Woodland Hills lots have room for an ADU or a garage conversion, and Los Angeles allows ADUs on lots zoned for single-family and multifamily use.

    We handle feasibility, design, permits and construction, from the first sketch through final inspection.

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.

FAQ

RnD Builders Woodland Hills FAQs

What does a remodel with RnD Builders cost in Woodland Hills?

For example, an interior remodel in Woodland Hills runs $75,000 to $250,000 and a kitchen $35,000 to $150,000. Bathrooms run $25,000 to $85,000, garage conversions $140,000 to $200,000 and detached ADUs $220,000 to $350,000, while additions start at $450 per square foot and custom homes at $650. Your personalized quote itemizes labor, design, materials and permitting, and your written estimate sets the exact price.

How long does a remodel take in Woodland Hills?

Scope, materials and complexity set your deadline. As a guide, a kitchen is guaranteed within 28 days and a bathroom takes about 3 weeks. Garage conversions take 3 to 6 weeks for basic work, ADUs are complete within 3 months of construction start and whole-home remodels run 4 to 6 months. We give each client a clear timeline based on the scope and complexity of the project.

How do LADBS permits work for a Woodland Hills remodel?

Permits run through the Los Angeles Department of Building and Safety. Some projects, such as kitchen and bathroom remodels with no structural changes, qualify for express permits, while additions, ADUs and structural work go through plan check. RnD Builders prepares the plans, submits them, handles corrections and coordinates the required inspections, so you do not have to navigate it yourself.

Can I add an ADU to my Woodland Hills property?

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.

What does a garage conversion cost in Woodland Hills?

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.

Does the Mulholland Scenic Parkway Specific Plan affect my remodel?

It can. Homes along the Mulholland corridor may fall under the Mulholland Scenic Parkway Specific Plan, and some scopes of work need a clearance sign-off from the city. We check your parcel against the plan before design so you know early what applies.

Do hillside rules apply to a Woodland Hills addition?

In designated hillside areas, the City of Los Angeles Baseline Hillside Ordinance sets limits on residential floor area and other hillside standards. We evaluate your lot early, so the plan, the schedule and the estimate reflect the slope.

Are Woodland Hills ranch homes good candidates for open-concept remodels?

Generally yes. Many 1950s ranch homes have compartmentalized floor plans that can be opened up, but any wall removal needs a structural review first. We also assess the framing, design the layout in 3D and handle the engineering and permits.

Can you match new construction materials to an existing Woodland Hills house?

Yes. Our design and build approach includes specifying and sourcing materials that match or complement your home's existing finishes and style. We review samples with you and adjust so new cabinetry, trim, siding or flooring look cohesive with the original house.

Do you offer guidance on maximizing property value in Woodland Hills?

Our team gives design recommendations focused on both livability and resale value, such as smart layout changes, appliance and finish selections and permittable additions or ADUs. The return depends on your market and the quality of the work, so we do not promise a specific amount.

Does RnD Builders build custom homes in Woodland Hills?

Yes. Custom homes start at $650 per square foot and generally take 11 to 20 months, and our 5,000 square foot Woodland Hills custom home is featured above. We also handle design, engineering, permits and construction. Hillside lots and complex site work add to the investment, and your written estimate confirms the exact price.

Why hire RnD Builders as your home remodeling contractor in Woodland Hills?

One team handles design, permits and construction, so plans are drawn with the build in mind. RnD Builders gives Woodland Hills homeowners 3D renderings, itemized written proposals and a single point of contact. We are based at 21250 Califa St in Woodland Hills. Whoever you hire, confirm the license, the written contract and the permits. 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 Woodland Hills?

Your written estimate lists the scope and each selection, and we check the site on the first visit. On older homes we check framing, plumbing and electrical before pricing. 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.

Does RnD Builders serve all of Woodland Hills?

Yes, we serve all of Woodland Hills, such as the flats south of the Boulevard, Walnut Acres, the Warner Center area and the hillsides near Mulholland. Our services extend across Los Angeles County and Ventura County. Ventura County is our main focus, such as Thousand Oaks, Newbury Park, Camarillo, Santa Rosa Valley, Oxnard, Ventura, Simi Valley and Moorpark. We also serve across Los Angeles County, including Westlake Village, Calabasas, Agoura Hills, Malibu, Woodland Hills, West Hills, Chatsworth, Northridge, Porter Ranch, Santa Clarita, Valencia, Pacific Palisades, Pasadena, Altadena and the South Bay.
