Frequently Asked Questions

Can I rent out my ADU in Lakewood, WA?

Yes! ADUs are allowed for long-term rental in Lakewood, and the city’s policies are highly ADU-friendly. Short-term rental rules (like Airbnb) can vary by specific zoning—contact us for a quick guidance check on your specific lot.

What is the maximum size for an ADU in Lakewood?

Lakewood allows detached ADUs (DADUs) up to 800 square feet. Attached units (like basement or garage conversions) can sometimes be larger depending on your lot size and existing footprint. We specialize in maximizing your livable space within these local constraints.

How long does it take to design and build an ADU?

Most projects take between 4 and 8 months from initial design to final walkthrough. This timeline includes the permitting process with the City of Lakewood, utility connections, and the actual construction phase.

Do ADUs increase property value and taxes?

Yes. An ADU adds livable square footage and potential rental income, which significantly boosts resale value. While adding a permanent structure may slightly increase your Pierce County property tax assessment, the "built-in" equity and monthly income potential typically provide a much higher return on investment.
