How Much Rent Can a Seattle ADU Earn?
By Eric Dexter, Owner & Builder ·
Rental income is one of the biggest reasons homeowners build a backyard ADU — so the natural question is: how much can you actually charge? In a high-cost market like Seattle, a well-built DADU can pull real monthly rent. Here's what shapes the number.
What ADUs rent for
There's no single figure — rent depends on the unit's size, location and quality. But because Seattle rents are high across the board, a finished, private DADU generally commands meaningful monthly income, often comparable to a small apartment in the same neighborhood. The best way to estimate yours is to look at comparable rentals nearby.
What drives the rent
- Size & bedrooms — a one-bedroom rents for more than a studio; two bedrooms more again.
- Location — neighborhood and proximity to transit and jobs move the number a lot.
- Quality & finishes — a bright, well-finished unit rents faster and higher.
- Privacy & parking — a separate entrance and a spot to park add real value to tenants.
Long-term vs. short-term
A standard lease gives you steady, low-effort income; a short-term rental can earn more per night but comes with more work and stricter local rules. We break down the trade-offs in renting out your ADU.
How rent offsets the build
This is the heart of the ROI: many owners put the rent straight toward the loan they used to build, so the ADU largely pays for itself over time while adding property value. See the full picture in is an ADU a good investment?
