Renovate Builders brings over 15 years of hands-on experience to ADU construction in Kingston, with more than 1,000 completed projects demonstrating our ability to deliver functional, code-compliant spaces that work for the way homeowners actually live. We focus on building accessory dwelling units that combine thoughtful design with solid construction – the kind of work that holds up over time and meets every local requirement.
Kingston’s housing shortage has created real demand for additional living space. An accessory dwelling unit on your property solves this directly – whether you need rental income, space for aging parents, or simply want to maximize what you already own.
Renovate Builders has spent 15 years building ADUs across Washington, completing over 1,000 projects from concept to completion. Our local team of 25+ professionals handles everything from initial design through permitting with Kingston city officials, utility coordination, and final construction. We know the local codes, the approval process, and what actually works on the ground.
What sets us apart is doing this work in-house. You’re not juggling contractors or waiting for someone else’s schedule. Our team manages design, engineering, permits, and building as one unit. That continuity matters – especially when navigating Kingston’s specific requirements and ensuring your ADU functions exactly as intended, legally and practically.
Adding an accessory dwelling unit to your Kingston property requires more than basic carpentry. ADU construction Kingston demands materials that stand up to our climate and a build approach that maximizes your investment. Whether you’re planning a backyard cottage, converting garage space, or finishing a basement suite, the right construction partner delivers both durability and compliance without compromise. Renovate Builders approaches each ADU project with three priorities in mind. First, we source materials rated for Kingston’s weather patterns and seasonal stress. Second, every unit meets current building codes from the ground up. Third, we structure the work to enhance your property value whether you’re generating rental income, accommodating family, or preparing for eventual sale. The specific layout matters less than the fundamentals. A basement suite, detached cottage, or garage conversion all benefit from the same rigorous standards – proper insulation, reliable systems, and materials that don’t degrade after five years. That foundation is what separates a quick build from one that performs.
Detached ADUs are small, independent units built separately from the main home and are also called “backyard cottages”. Have an underused backyard space? You can make it useful through long-term rentals or multigenerational living with the help of detached ADUs. Call us for site planning, custom design, permitting, and full build.
Attached ADUs share at least one wall or structural component with the main home. We also call them home extensions or garage ADUs, as they are usually built over garages or as side additions. Need a space for in-law suites or flexible rental space with shared utilities? This option is for you that adds luxury and comfort to your lifestyle.
Conversion ADUs are garage or basement conversions. We use existing square footage, like basements, attics, or garages, and transform them into livable units. This option is best for fast turnaround and lower cost-per-square-foot, making it ideal for short-term rental or guest suites.
Renovate Builders designs and constructs custom detached ADUs built to Kingston’s zoning requirements while making the most of your property. Whether you’re looking at a studio, one-bedroom, or two-bedroom layout, these standalone structures work well for short-term rentals, permanent tenants, or multi-generational arrangements. Each unit includes a full kitchen, independent bathroom, and modern energy-efficient construction that strengthens long-term asset value and opens up rental income potential.
Our garage conversion service transforms an underused space into a legal, livable unit. We handle structural retrofitting, insulation, plumbing, and electrical upgrades. Need home offices, rental units, or guest quarters? Garage conversion is your best cost-effective alternative to new builds. Increase usable square footage and get a strong ROI without expanding outward.
Expand your home’s square footage without moving, with our room addition services. Add bedrooms, bathrooms, family rooms, gyms, or office space for your growing family or simple lifestyle upgrade. Our team makes sure that all additions match the existing structure and architecture. Let us help you boost appraisal value and functionality in residential zones.
Second-story additions are perfect for homeowners needing more space without sacrificing yard area. We build up, adding full floors or partial pop-tops to maximize views and living space. This is ideal for land-locked Kingston neighborhoods, delivering a major property value increase while supporting long-term living without relocating.
For added privacy and flexibility, backyard cottages in Kingston are a popular choice. These detached living units, also called DADUs or sometimes referred to as in-law suites (when used for extended family housing). Our team completes them with kitchens, bathrooms, and private entrances. Highly useful for families with aging parents, adult children, or renters. Enjoy living independently while increasing property value and long-term rental income.
ADUs generate consistent passive income through short- or long-term rentals. It’s one of the lowest-barrier ways to invest in real estate without buying a second property or moving out.
And if you do relocate, it’s known that Kingston homes with ADUs consistently sell for more. Buyers value extra rentable space, which means your property stands out in listings.
Adding an ADU gives your property long-term flexibility. Enjoy a livable space for aging parents, adult kids, or a future home office. It adapts to your lifestyle while preserving privacy and personal space.
We evaluate your lot for zoning, access, and size constraints before beginning any design or permitting process.
Our in-house team develops detailed drawings optimized for layout, light, and utility performance before submitting permit applications.
Once approved, our crew begins excavation, foundation, framing, and finishes. You’ll get a fully permitted, move-in-ready ADU or DADU.
Whether you want premium finishes or need a cheap, affordable option, we offer scalable design-build solutions without sacrificing quality. From zoning headaches to DADU footings, we solve it, manage it, and finish it, because that’s what the best ADU builders Kingston should do.
ADU costs range from $100,000 to $350,000+, but the exact price depends on the size, layout, location, and type (like garage conversion or detached unit). Call us for a custom quote!
