Questions about Multi-Gen / ADU Living Guide
Clear answers first. If one question changes the deal, bring it into the review before you move money.
Q1What are the two ways to set up multi-gen living?+
A home built for it (a main-floor primary plus a separate suite or legal in-law unit) or adding an ADU/DADU. Each has different layout, regulatory, and financing angles — choosing between them is the first decision.
Q2What makes multi-gen living actually work day to day?+
Privacy: separate entrances, and kitchen and bath autonomy for each household. Setups that share everything strain; those with real separation and independence tend to last.
Q3What do I verify before counting on an ADU?+
Zoning, permits, owner-occupancy, and parking rules with the city. Washington has loosened ADU rules, but local specifics still govern what you can build and rent — confirm before you plan around it.
Q4How does accessibility factor in for aging parents?+
Heavily. A multi-gen setup for aging parents should include a main-floor or step-free suite and bathroom safety features. Designing for accessibility from the start avoids a second renovation as needs change.
Q5Does an ADU add value beyond housing family?+
Yes. A legal ADU houses family now and can become an income or equity asset later, adding flexibility a purpose-built in-law layout doesn't. That optionality is a reason to favor a permitted, separable unit.
Q6How do I find a multi-gen home or ADU-friendly lot?+
Screen for a suitable layout or ADU-permitting zoning, and confirm the rules before buying. Targeting those properties is part of a Real Estate Review.
