ADUs and Tiny Homes

As Olympia’s premier, eco-friendly General Contractor, we specialize in building Accessory Dwelling Units (ADUs). Also known as Mother-in-Law suites, ADUs and Tiny Homes make for incredible investments. With an average ROI of 7 years, rental income more than covers the mortgage costs.

If you’re looking to bring mom and dad back home for a long-term living situation, we are your go-to partner. We’ve built multiple Tiny Homes in Thurston County specifically with ADA Accessibility features for aging in place. We manage the entire process from site planning and design to utility connections and construction.

We are huge advocates of Olympia’s Preapproved ADU plan sets. If you own property within City Limits, consider choosing from one of four preapproved design plans. By doing so, your project will be fast-tracked through the permitting process and will not require additional engineering costs. Reach out for more info!
