Seattle Tiny Homes: Small-Footprint Building Options in Buckley, WA
Based in Buckley, Washington, Seattle Tiny Homes has been building compact living structures since 2005. The company focuses on homes measuring 400 square feet or smaller, offering a range of construction types suited to different budgets, site conditions, and intended uses. Whether the goal is a backyard cottage, an in-law suite, or a detached accessory dwelling unit, Seattle Tiny Homes works with clients to match the right build type to their property and needs.
As an accessory dwelling unit builder, the company recognizes that small structures serve a variety of purposes beyond a primary residence. A tiny structure can function as a mother-in-law apartment, a retirement cottage, an extra bedroom for a college student living at home, a home office, or a standalone studio. This flexibility is part of why tiny homes and ADUs have grown in popularity across Washington State, particularly as housing costs rise and homeowners look for ways to add usable space to existing lots.
Build Types Offered
Seattle Tiny Homes provides three primary construction categories, each suited to different goals:
- Travel Trailer Homes: Certified tiny homes built on a travel trailer chassis, intended as a portable housing solution for a backyard or park-style setting. These structures can often sidestep certain permitting requirements since they're classified as RV travel trailers.
- Park Model Homes: Starting at 10 feet wide, Park Model RVs (PMRVs) offer more interior space while still allowing for portability. They can serve as either temporary or permanent housing in Washington, depending on local jurisdiction rules.
- Modular Homes: For those seeking a permanent structure, factory-built modular homes represent the lowest-cost construction option and are commonly used for detached ADU (DADU) projects or standalone tiny houses.
Each tiny home is designed and certified by Washington state to meet or exceed ANSI 119.2 or 119.5 standards, and the company follows IRC construction standards wherever applicable. With proper preparation, tiny houses on wheels built by Seattle Tiny Homes can often be permitted in many jurisdictions as full-time residences, or alternatively registered under travel trailer classifications to simplify the permitting process.
Legal Framework and Support Services
Tiny homes are legal in Washington State. Seattle Tiny Homes played a role in this by helping establish the Washington Tiny House Association, a non-profit trades movement, in 2016. The organization worked through legislative efforts culminating in 2018, which created a formal pathway for tiny homes on wheels and small developments of 400 square feet or less. Additional information on the legal landscape is available through Legaltinyhouses.org.
Beyond construction, the company offers consulting services in partnership with the Washington Tiny House Association, helping prospective owners understand zoning, permitting, and site requirements. A sister company, Trueland Development LLC, provides land development support for clients working through the broader logistics of establishing a tiny home or ADU on their property.
Financing for tiny homes can present challenges compared to traditional home loans. Seattle Tiny Homes notes that options such as Chattel Loans, which typically require 20% down with a 25-year term, or 10-year RV loans, are available paths for clients to explore. All completed structures come with guarantees and warranties, and the company also works with clients on extended appliance warranties.
The factory location in Buckley, WA, operates by appointment only, allowing the team to provide focused attention during tours and consultations for those exploring a tiny home, granny flat, or backyard ADU project.
