Tiny Homes in Spokane, WA
Spokane Tiny Homes and ADUs Built On-Site, From the Foundation Up
We build custom ADUs and tiny homes in in Spokane, Spokane Valley, and Spokane County. Every build is designed for your specific lot and constructed on-site from the foundation up, not assembled elsewhere and delivered. We manage the permits, the design, and the build, and we work only in this region, which means we already know what your jurisdiction will ask for.
We specialize in detached units, attached additions, and garage conversions.
Your Vision. Our Expertise.
If you are looking for tiny homes in Spokane built around your property and your life, you have found the right builder. Brio Tiny Homes has been designing and building in this region long enough to know what works here.
For some, it’s a backyard ADU that generates rental income while the family stays close. For others, it’s a smaller, intentionally designed home built around how they actually want to live. Whatever the vision, we build it custom, on-site, and to fit your life.
We know this area’s permit process, zoning requirements, and the practical realities of building here. You bring the vision. We handle everything else.
Tiny Homes and ADUs for the Spokane Area
Serving Spokane, Spokane Valley, Spokane County, and Surrounding Communities
Every property is different. Every goal is different. As accessory dwelling unit builders, we start by understanding which approach fits your land, your life, and what you are trying to accomplish.
Detached ADUs
A fully separate structure on your property: private, flexible, and built from the ground up. Whether you’re adding a rental unit for passive income, a guest house for family, or a long-term housing option for aging parents, a detached ADU gives you an independent space that works alongside your home.
Attached ADUs
Additional living space connected to your existing home. An attached ADU shares a wall with the primary residence but functions as its own unit. It’s a practical solution for multigenerational living, a private suite for a family member, or a rentable space that stays close.
Garage ADUs
Your existing garage, reimagined as livable space. A garage conversion makes use of what’s already on your property. We design around your parking and storage needs while creating a fully functional living area above, beside, or in place of the existing structure.

We know Spokane
Building in Spokane comes with local complexities that out-of-area builders are not equipped to navigate. Our Brio team knows how the city’s ADU ordinance differs from Spokane Valley’s, and which neighborhoods have the lot coverage allowances that make a backyard build feasible.
Local experience is not just about knowing the codes. It’s also about knowing what questions to ask before a single board is cut, and building a plan that holds up when it meets the real world.
These are a few of the tiny homes and ADUs we’ve built across the Spokane area.
How It Works
Building a tiny home or ADU here does not have to be complicated. Here is what the process looks like.
Evaluation
Schedule a free consultation with our team. We assess your property, talk through your goals, and provide a detailed estimate based on your specific site and vision.
Customized Design
We work with you to select and customize a floor plan that fits your site and your life. Every detail gets considered before a single permit is filed.
Permitting
We manage the permit process from start to finish. Spokane and Spokane Valley have specific ADU and tiny home requirements; we handle them so you don’t have to learn them yourself.
Construction
Construction happens on-site, on your property. We stay in close communication throughout the build so you always know where things stand.
Final Walkthrough
Before handoff, we conduct a thorough walkthrough to ensure every detail meets our standards and your expectations. Once approved, your ADU is move-in ready.
Built Different.
Built for You.
Built for Spokane.
Every Brio build starts with a conversation, not a catalog.
Brio designs and builds on-site, custom to your property and your goals, from the foundation up. Your tiny home or ADU is built to fit your land, your aesthetic, and your life. It’s not pulled from a catalog or assembled off-site. That difference matters, and you’ll feel it from the first conversation.
From the first site visit through the final walkthrough.
You have a team behind you through every step of the process. We handle permits, planning approvals, and the paperwork that tends to slow people down. In Spokane and Spokane Valley, ADU regulations and tiny home codes have specific requirements that can trip up builders who don’t know the area. We navigate that process so you don’t have to figure it out yourself.
Frequently Asked Questions
Still have questions? Get in touch with our team and we will answer them straight.
Do you build custom tiny homes in Spokane Valley?
Yes. Spokane Valley is one of our core service areas and a good share of our completed builds are there. Every jurisdiction in the county handles ADUs a little differently, and we manage that side of it for you as part of every build.
What's the difference between a tiny home and an ADU?
A tiny home is a dwelling designed around a smaller, more intentional footprint, typically under 400 square feet. An ADU (accessory dwelling unit) is a structure added to a property that already has a primary residence. Both can serve similar purposes: rental income, housing a family member, or a lifestyle choice. The right option depends on your property, your goals, and your local zoning. We can help you figure out which makes sense.
How long does it take to build a tiny home in Spokane?
It depends on the complexity of the design and your site conditions. We will give you a realistic timeline during your consultation, not an optimistic one. Most clients should plan for several months from first conversation to move-in.
How much does it cost to build an ADU in Spokane?
Cost depends on the floor plan, site conditions, finishes, and any site preparation work required. We don’t publish a single number because every build is different, but we’re transparent about cost from the very beginning of the process. Schedule a consultation and we’ll walk you through what a realistic budget looks like for your project.
Where else do you build ADUs?
In addition to Spokane and Spokane Valley, we build ADUs and tiny homes throughout North Idaho, including Coeur d’Alene, Sandpoint, Post Falls, and Hayden. Wherever you’re located in our service area, our team handles the permits, planning, and process so you can focus on the life you’re building.
Do you build accessory dwelling units, or only tiny homes?
Both, and in practice most of our projects are ADUs. An accessory dwelling unit is a second independent dwelling on a lot that already has a house, which describes the majority of what people come to us for. Detached, attached, or a garage conversion, we build all three.
Can you build a guest house on my property?
Yes. A guest house and a detached ADU are usually the same structure with different names attached to it. If you want somewhere for family to stay that is genuinely separate from the main house, that is a detached ADU, and it is the most common thing we build.
Do you build on-site, or deliver a finished unit?
On-site, every time. We pour the foundation and build on your property, which means the design can respond to your actual lot instead of arriving as a fixed box. It is slower than dropping in a prefab unit and it produces a better result, and it is the main reason clients come to us.
