Who does this
Nobody does it for the square footage.
For your parents
Close, but separate
Sunday dinner together. Every evening apart. Instead of $6,975 a month in assisted living (Genworth, 2024).
For grown kids
A first place nearby
More than half of 18-to-24-year-olds live with their parents — 57% of men, 55% of women (U.S. Census, 2024). Everyone gets their door back.
For income
Rent that carries the mortgage
A one-bedroom in Everett rents for a median $1,545 (Zumper, Sept. 2026).
For later
An address you can sell
State law lets the unit be sold as its own condo.

Three quick questions
Do I have to live on the property?
In most Washington cities, no. Your report says which rule your city uses.
How big can it be?
Cities can't cap it under 1,000 sq ft. Your setbacks usually decide first.
Can I sell it separately?
State law says yes, as a condo. The report says whether that's realistic on your lot.
