Property Eligibility
Is My University Place, WA Property Eligible for an ADU?
University Place homeowners benefit from California's state ADU law — one of the most permissive frameworks in the country since 2020. Here's what applies to your property before you start designing.
Single-Family Home
Permitted on single-family lots in University Place under California state law. University Place requires owner occupancy — the property owner must reside in the primary home or the ADU. Ministerial permit approval — no neighbor input or discretionary design review.
Multi-Family Property
Up to 2 detached ADUs plus JADUs (Junior ADUs) within the existing main structure are permitted under California state law. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 0% of University Place homes are in an HOA. California law (AB 670) prohibits HOAs from banning ADUs outright, but they can impose reasonable architectural standards. Our drawings include HOA submission formatting.
Coastal Zone Properties
Properties within University Place's Coastal Overlay Zone require a Coastal Development Permit (CDP) in addition to standard building permits. This adds 2–6 months to the timeline. Our drawings flag coastal requirements and meet both local and Coastal Commission standards.
Always verify eligibility with Planning & Development Services before designing.
