Find the Right Roy Home with Additional Living Space

Attached ADUs

Secondary living areas connected to the main house may provide separate access and facilities. Confirm permitted use.

Detached ADUs

Backyard cottages and separate dwellings may offer privacy. Review utilities, setbacks and permit records.

Mother-in-Law Suites

Guest suites and converted living areas are not necessarily permitted independent residences.

Important Questions Before Buying in Roy

Confirm whether the property is within city or county jurisdiction, whether the additional dwelling is permitted, and whether zoning, HOA rules or deed restrictions affect use. Review separate entrances, parking, utilities, kitchens and occupancy. Where applicable, check septic approval and capacity. Discuss ADU financing and appraisal treatment with your lender.

MLS ADU labels are useful search signals but do not independently establish legal rental eligibility. Compare each home's condition, layout and documented improvements.

What Is Your Roy ADU Property Worth?

Homes with a permitted secondary unit can appeal to a broader set of buyers. Pricing should consider the quality of the space, legal status, neighborhood and recent comparable sales rather than assuming a fixed ADU premium.

Welcome to an almost twelve-acre estate with Mt. Rainier views, offering nearly 4,700 square feet of living space across two distinct custom, quality homes and a standalone studio, a brand new 1,808sf RV garage/shop, an almost 1,000sf attached garage, a barn, and more, all behind an impressive electronic gate. Built for every stage of life, the 3-bedroom, 2.5-bath main residence dazzles with vaulted ceilings, tons of natural light, a chef's kitchen built for gourmet cooking, and a primary suite with a huge walk-in closet and spa-style ensuite bath, all just nine years young. A newly remodeled, gorgeous 2-bedroom, 2-bath second home, complete with its own address, driveway, laundry room, and large open living space, opens the door to multigenerational living or real rental income. Just steps away, a studio offers flexible space for a home office or creative space. Horse lovers and hobbyists will find a working barn and fenced pasture ready for livestock and projects alike. Outside, the grounds unfold into a private retreat of their own: a fountain-anchored circular drive, arbors, a gazebo, and endless sitting areas. Just 15 minutes from JBLM's East Gate, Tanwax and Clear Lakes, and easy access to Tacoma and Olympia. Properties with this combination of acreage, location, shop/garage space, and living space rarely come to market. Picture your morning coffee on the patio, watching horses graze in the pasture.
