Our process

Our Redondo Beach Process

  1. Consultation

    Your designated specialist will meet with you at your home in Redondo Beach. Your designer will be handpicked for your project based on their skill and local knowledge. They go over your vision, noting key details to provide your initial, no-commitment quote.

  2. Design & Plan

    With 3D modeling, you can see every detail of your project before we start our work. With open communication and flexibility, we ensure you can adjust any element until the design perfectly aligns with your vision.

  3. Select Materials

    Our vast supplier network gives you access to premium and eco-friendly materials. You can also order custom pieces made specifically for your project.

  4. Build Begins

    We set a deadline (which we always stick to), and then we get to work. Our approach aims to optimize the process while minimizing any impact on your daily routine. We can also make in-project updates to ensure progress matches your vision.

  5. Handover

    We don't stop until you are fully satisfied. No detail overlooked, no corners cut. After the final walkthrough, we hand over the keys and let you start enjoying your renovated home.

Local know-how

Redondo Beach Local Know-How

Four things that shape a Redondo Beach remodel.

  • Coastal Zone Review

    Properties in the coastal zone add a review layer for major exterior work, and eligible projects may need a Coastal Development Permit.

    We confirm your parcel's status before design begins, so coastal review is part of the plan and the schedule.

  • North and South Redondo

    North Redondo offers bigger lots and addition potential. In addition, south Redondo and the Esplanade corridor trade space for coastal proximity and higher finish expectations.

    We plan each project around the lot and the neighborhood it sits in.

  • Second Stories on North Redondo Lots

    Many North Redondo lots can support a second story that turns a two-bedroom cottage into a full family home. Second-story additions generally start at $450 per square foot.

    We assess structure and zoning in a feasibility visit before you commit.

  • Townhome Interiors

    Townhome remodels come with HOA coordination, party-wall considerations and the logistics of multi-level interior work.

    We plan staging, noise and access with the association and your neighbors before work starts.

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 Redondo Beach FAQs

How much does a remodel with RnD Builders cost in Redondo Beach?

Cost depends on materials, scope and permitting. As a guide, kitchens run $35,000 to $150,000, bathrooms $25,000 to $85,000 and interior remodels $75,000 to $250,000. A new detached ADU runs $220,000 to $350,000 and a garage conversion $140,000 to $200,000, additions start at $450 per square foot and custom homes at $650. Coastal review and tight lots can also add to a project. After your consultation you receive a personalized, no-commitment quote, and the written estimate confirms the exact price.

How long does an RnD Builders project take in Redondo Beach?

Your project manager gives you a written schedule based on the scope. For example, kitchens are guaranteed within 28 days, bathrooms take about 3 weeks, garage conversions 3 to 6 weeks for basic work, ADUs under 3 months from the first day of construction and whole-home remodels 4 to 6 months. Redondo Beach's coastal climate still allows steady remodeling work in any month. In addition, permit approval and design come first on bigger jobs.

Who handles permits for a Redondo Beach remodel?

RnD Builders prepares the plans and submittals and manages corrections and inspections. In addition, the city's Building and Safety Division takes applications, plans and related documents electronically through its CTS portal, and most residential work on private property, whether new, added, remodeled or altered, needs plans and a permit.

Does my Redondo Beach project need a coastal permit?

If your property is inside the coastal zone, major exterior work adds a review layer and eligible projects may need a Coastal Development Permit. We confirm your parcel's status before design begins and manage the submittal if coastal review applies.

Can I build an ADU in Redondo Beach?

Generally yes. In addition, the city offers a streamlined process for detached ADUs under AB 1332 and a 60-day approval timeframe for complete applications. Setbacks and size depend on your lot, so we confirm what fits at the consultation and handle design, permits and construction.

What does a garage conversion cost in Redondo Beach?

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.

Can I add a second story to my Redondo Beach cottage?

Many North Redondo lots support it. Second-story additions generally start at $450 per square foot, and the total depends on size, structure and finishes. We assess structure and zoning in a feasibility visit before you commit.

Do you renovate townhomes in Redondo Beach?

Yes, and we also handle HOA coordination, party-wall considerations and the logistics of multi-level interior work. We plan staging, noise and access with the association before work starts.

What does a bathroom remodel cost in Redondo Beach?

Bathroom remodels generally run $25,000 to $85,000, depending on size, layout changes and finishes, and a standard bathroom takes about 3 weeks. Primary suites and luxury specifications can also run higher, and we confirm the exact price in a written estimate after we see your space.

What does a kitchen remodel cost in Redondo Beach?

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.

How do North and South Redondo differ for remodeling?

North Redondo offers bigger lots and more addition potential, while South Redondo and the Esplanade corridor trade space for coastal proximity and higher finish expectations. In addition, beach cottages, mid-century family homes and modern townhomes each remodel differently, and we plan around the lot and the style.

Why hire RnD Builders as your home remodeling contractor in Redondo Beach?

We combine design, engineering support, permits and construction in one company, which shortens the handoffs that cause delays. Whoever you hire for a Redondo Beach remodel, check the license, read the written contract and confirm every required permit is pulled. License #1081122 is our California general contractor license, and the CSLB website lets you verify it. California requires a license for any project that needs a permit or totals $1,000 or more, so request the license number from every contractor you consider.

How does RnD Builders prevent surprise costs in Redondo Beach?

Surprise costs usually come from unchecked conditions, so we look at the site before we price. On coastal and older homes we also check moisture, framing and existing systems before pricing. Your estimate is itemized, changes are agreed in writing before they are added, and the project stays in line with the budget agreed in your contract.

Which Redondo Beach neighborhoods and nearby cities does RnD Builders serve?

We serve North Redondo, South Redondo, the Esplanade corridor and the Avenues, plus Manhattan Beach, Hermosa Beach, El Segundo and the wider South Bay. 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.
