Find the Right Build for Your Lot
A DADU opens up possibilities that most homeowners don't realize they have. Rent it out and generate monthly income. Create a private space for an aging parent or returning college student. Add a home office, studio, or guest suite. Or simply increase the long-term value of a property you already own. Whatever your situation, there's likely a DADU solution that makes sense for your lot — and we're here to help you figure out what that looks like.
DADU Construction
A DADU is a fully independent, freestanding structure built on your existing lot — separate from your main home with its own entrance, utilities, and living space. Available in a range of sizes from compact to multi-level.
ADU Construction
An ADU is an accessory dwelling unit that is attached to or built within your existing home — think a converted basement, an addition, or an attached unit sharing a wall with the primary structure. A good option for lots where a separate freestanding structure isn't feasible.
Garage Conversions
A garage conversion transforms an existing attached or detached garage into a permitted, livable space. The existing structure is retrofitted to meet residential building code and city permitting requirements.

Tacoma DADU & ADU FAQs
Answers to the most common questions homeowners ask about the process of adding a DADU unit to their property.
What is a DADU and how is it different from an ADU?
A DADU — detached accessory dwelling unit — is a fully independent structure built on your existing lot, separate from your main home. An ADU can be attached or interior. Both are legal, permitted living spaces — the difference is whether they're connected to the primary structure or freestanding.
Can I build a DADU on my lot in Tacoma?
Most single-family lots in Tacoma zoned R-1 or R-2 allow DADUs. Setback requirements, lot size minimums, and allowable square footage vary by zone. We do a free lot assessment to give you a definitive answer before any money changes hands.
How much does a DADU cost in Tacoma?
Costs vary based on model size, lot conditions, utility connections, and finish level. Our completed projects range from our compact McKinley model through to fully finished 1,000 sq ft builds. Contact us for a real number based on your specific lot and goals.
How long does it take to build a DADU in Tacoma?
From consultation to certificate of occupancy, most Tacoma projects run 10–14 months. Permit timelines at the City of Tacoma and TPU utility approval are the biggest variables — we'll give you a realistic timeline based on current conditions when we assess your lot.
What are the setback requirements for a DADU in Tacoma?
Tacoma updated its DADU setback rules in February 2025, reducing the rear setback requirement to 10 feet. Side setbacks vary by zone. We verify your specific parcel before design begins to make sure we're maximizing your buildable area.
Does Tacoma DADU handle permits?
Yes — permitting is included in our full-service process. We handle the entire City of Tacoma permit application, TPU coordination, and all required inspections through to certificate of occupancy.
