Is an ADU Right for Your King & Pierce County Property?

A quick overview of zoning, use cases, and what to consider before you commit to an accessory dwelling unit.

ADUs and DADUs can create flexible space for family, guests, or rental income — but they’re not the right fit for every property. Before you dive in, it helps to understand how your lot, goals, and budget line up with what’s possible.

Check your zoning and lot conditions

Lot size, setbacks, height limits, and parking requirements all influence what kind of unit you can build. A quick feasibility review can clarify whether an attached ADU, detached cottage, or interior conversion makes the most sense.

Clarify how you want to use the space

Long-term rental, short-term guests, multigenerational living, or a dedicated office all have slightly different layout and privacy needs. Defining the primary use up front helps us design accordingly.

Run the numbers realistically

We’ll help you understand construction costs, soft costs (design, permits, utility upgrades), and what kind of rent or long-term value you’re likely to see in your specific neighborhood.
