Our process

Our Thousand Oaks Process

Local know-how

Home Remodeling in Thousand Oaks: Local Know-How

Four things that shape a Thousand Oaks remodel.

  • Conejo Valley Tract Homes

    Solid 1960s to 1980s tract construction is the story here, with floor plans that no longer match how families live.

    We plan kitchen wall removals, primary bath expansions and full-home refreshes that update the house while keeping its structure.

  • HOA Design Review

    Many Thousand Oaks neighborhoods have HOA design review in addition to the city permit.

    We prepare both packages together so the HOA and the city reviews move side by side.

  • Surprises in 1970s Homes

    Aluminum wiring, galvanized plumbing and undersized panels are common in homes of that era.

    We check for all three during the assessment, so your budget is realistic from the start.

  • Protected Trees

    The city requires a permit for work that impacts a protected tree or the soil in its protected area.

    We look for protected trees on your lot at the first visit and plan the design and equipment access around them.

Where we work

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.

How long does remodeling take in Thousand Oaks?

Most single-room projects are measured in weeks and whole-home projects in months. Kitchens are guaranteed within 28 days, bathrooms take about 3 weeks and basic garage conversions take 3 to 6 weeks. A detached ADU is finished within 3 months of the first day of construction, while a whole-home remodel takes 4 to 6 months.

Who handles permits for remodeling in Thousand Oaks?

RnD Builders prepares the plans and submittals and manages corrections and inspections. The city's TO/24 online service handles permit applications, plan checks and inspection scheduling, and land use applications also go through TO/24.

Do I need a permit to work near protected trees in Thousand Oaks?

Possibly. In addition, the city requires a permit for any work that impacts a protected tree or the soil in its protected area, other than removing dead wood. We check your lot during the first visit and plan the design and equipment access around protected trees.

Does RnD Builders handle HOA design review in Thousand Oaks?

Many Thousand Oaks neighborhoods have HOA design review in addition to the city permit. RnD Builders prepares both packages together so the HOA and city reviews move side by side, and the HOA sets its own approval timeline.

Can I build an ADU or convert space in Thousand Oaks?

Generally yes. In addition, the city regulates ADUs and JADUs under its municipal code, and ADUs follow the development standards of their zone. We also convert garages into ADUs and finish attic or garage space into suites, guest units or home offices.

Can you convert attics or garages in Thousand Oaks homes?

Yes. We regularly convert garages into ADUs and finish attic or garage space into livable suites, guest units or home offices. We start with your vision for the space, then handle design, structure, permits and construction.

Do zoning codes in Thousand Oaks limit the size of additions?

Yes. Local zoning and building codes determine allowable floor area, setbacks and lot coverage, which can limit the size and placement of an addition. We review the rules early and tell you what is feasible, or whether another approach fits better.

Which outdoor living upgrades are most popular in Thousand Oaks?

The most popular upgrades are outdoor kitchens, deck or patio expansions and hardscape features such as retaining walls and low-maintenance landscaping that extend usable outdoor living space. Outdoor kitchens generally run $35,000 to $150,000.

Do 1970s Thousand Oaks homes have remodeling surprises?

Sometimes. Aluminum wiring, galvanized plumbing and undersized panels are common in homes of that era. We check for all three during the assessment so your budget is realistic from the start.

Do you have completed projects I can see in Thousand Oaks?

Yes. We have completed more projects in and around Thousand Oaks than in any other city, such as full home transformations, kitchens, bathrooms and patio covers. See the project links on this page, and we can arrange references from local homeowners.

Why hire RnD Builders as your home remodeling contractor in Thousand Oaks?

One team handles design, permits and construction, so plans are drawn with the build in mind. RnD Builders gives Thousand Oaks homeowners 3D renderings, itemized written proposals and a single point of contact. Whoever you hire, confirm the license, the written contract and the permits. Yes, we are a licensed California general contractor, License #1081122. You can confirm it on the CSLB website, and in California a contractor license is needed for projects that require a permit or total $1,000 or more.

How does RnD Builders prevent surprise costs in Thousand Oaks?

We itemize your quote from the scope you approve so nothing is hidden. On older tract homes we check wiring, plumbing and the electrical panel before pricing. Before pricing, we review existing conditions on site, and any change is agreed with you in writing first, so the project stays in line with the budget agreed in your contract.

Which Thousand Oaks neighborhoods does RnD Builders serve?

We serve Newbury Park, Dos Vientos, Lynn Ranch, Wildwood, Conejo Oaks and Lang Ranch, plus neighboring Westlake Village and the wider Conejo Valley. Ventura County is our main focus, and we also work across Los Angeles County.
