ADU Strategy
Henos Adhana of eXp Realty helps Seattle, Eastside, and north-end owners weigh whether an ADU fits their property and their goals.
An accessory dwelling unit, or ADU, is a smaller second home on the same lot as your main house. In Seattle that can mean a converted basement, an attached unit, or a detached backyard cottage. Deciding whether to add one is as much a real estate decision as a construction decision, and that is where an ADU strategy starts.
Before you talk to a builder, it helps to understand how an ADU could change your property's value, your options for renting or housing family, and how it fits the way you plan to use the home over time. As your agent, Henos Adhana walks through those questions with you so the plan matches your budget and your timeline.
Whether you are buying a Seattle home with ADU potential, already own one and are considering adding a unit, or want to sell a property that has one, the goal is the same: a clear, honest read on what makes sense for you.
What an ADU can do for you
An ADU can create rental income, house an aging parent or an adult child, or give you a flexible space that supports the main home's value. The right use depends on your goals, so we start by naming them: income, family, resale, or a mix.
From there, we look at your specific lot and neighborhood to see which of those outcomes is realistic and what the tradeoffs are. Not every property is a strong candidate, and part of the value is knowing that early.
Zoning and feasibility in Seattle
Seattle allows both attached and detached accessory dwelling units on many single-family lots, but the rules around size, height, parking, and setbacks vary by zone and by lot. What is permitted in Ballard may differ from Wallingford or Greenwood.
We review your zoning, lot dimensions, and any constraints together, and connect you with the right professionals for permitting and design questions. The aim is to give you a grounded picture before you commit time or money.
How it fits a buy or sell decision
If you are shopping, ADU potential can be a reason to favor one property over another, and we can factor it into how we evaluate homes and structure your offer. If you already own the property, an ADU is one of several ways to use it, and it should be weighed against selling, remodeling, or simply staying put.
When it is time to sell a home that has an ADU, we position that unit clearly for buyers so its value is understood rather than overlooked.
Where I work
A few areas where this comes up often:
Common questions
What is the difference between an ADU and a DADU?
An ADU is any accessory dwelling unit, which includes attached units and converted spaces. A DADU is specifically a detached unit, such as a standalone backyard cottage.
Can I add an ADU to my Seattle home?
Many single-family lots in Seattle allow one, but it depends on your zone, lot size, and site constraints. We can review your property together to see whether it is a realistic candidate.
Does an ADU add value to a property?
It can, through added living space and potential rental income, though the effect varies by neighborhood and by how the unit is built and used. We look at your specific situation rather than a general rule.
Should I build an ADU before selling?
Not always. Building is a significant investment, so we weigh the likely return against your timeline and goals before recommending it as part of a sale.
How do we get started?
Reach out to Henos Adhana for a conversation about your property and what you want the ADU to accomplish, and we will map out sensible next steps from there.
