Quick Answers About University Place, WA ADUs
Market Context
University Place has a median home value of $460,000. Adding an ADU typically increases that by 28% — approximately $128,800 in added equity. A 1-bedroom ADU in University Place rents for approximately $1,513/month in the Pierce County rental market , yielding a 5.2% cap rate on the investment. Occupancy averages 97% in this market.
Top University Place neighborhoods for ADU investment include Town Center / Bridgeport, Curran / Cirque, Beckonridge, Sunset Beach, Soundview / North End. Walkable core with restaurants/jobs and strong rental demand — ideal for ADU rentals. Established single-family streets with larger lots, making detached ADUs feasible.
Permit Process
Permit applications are reviewed by the Planning & Development Services , with a plan check timeline of approximately 9 weeks. Permit fees in University Place range from $2,800 to $9,500 depending on project scope. Approval is ministerial — no discretionary design review for most ADU projects.
University Place properties within the Coastal Overlay Zone require a Coastal Development Permit (CDP) in addition to standard building permits. CDPs add 2–6 months to the permit timeline and require compliance with both local ordinances and applicable state coastal zone management standards.
Because much of University Place falls within the Puget Sound shoreline jurisdiction, any ADU within 200 feet of the water triggers a Shoreline Substantial Development Permit review layered on top of your standard building permit — this typically tacks on 6-8 weeks because Planning & Development Services has to route it through a separate environmental checklist before your building plans even get looked at. On top of that, since University Place sits in Seismic Zone D1, engineers often require additional shear wall or foundation anchoring details for detached ADUs, which can mean a second round of structural review if your first submittal doesn't address it upfront. And don't plan on recouping costs through Airbnb — the city's short-term rental ban means your ADU has to pencil out as long-term housing or family space from day one.
"In my experience with University Place clients, that 9-week timeline and $250/sqft figure read as statewide averages rather than what's actually happening on the ground here, so I'd push you to get real local contractor quotes and call Planning & Development Services directly before penciling in a budget or schedule. What the data also doesn't show is the coastal overlay — the CDP review it triggers has, in my experience, added months rather than weeks to projects near the shoreline, so factor that in early. — Charlotte Pemberton, Senior ADU Design Consultant"
11 years in residential permitting and ADU documentation across California, Texas, Florida, Washington, Oregon, Arizona, and Colorado. This guide was researched and verified against University Place's building department records and current 2026 Washington's HB 1337 ADU law.
Property Eligibility
Is My University Place, WA Property Eligible for an ADU?
University Place homeowners are governed by Washington's HB 1337 (2023). Here's what applies to your property before you start designing.
Single-Family Home
Permitted on single-family lots in University Place under Washington's HB 1337 (2023). University Place requires owner occupancy — the property owner must reside in the primary home or the ADU. The state requires administrative (non-discretionary) review, though it doesn't set a fixed statutory day-count the way California's law does — confirm the current timeline with the Planning & Development Services.
Multi-Family Property
Additional ADUs on multi-family and duplex lots may qualify under Washington's HB 1337 (2023) — the exact number and type allowed depends on University Place's local rules. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 0% of University Place homes are in an HOA. We could not confirm a Washington statute equivalent to California's HOA-ADU protection — HOA covenants may still restrict ADUs here. 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 applicable state coastal zone management standards.
Always verify eligibility with Planning & Development Services before designing.

Projected Returns
* Estimates only. How we calculate this: Annual gross rent = monthly rent × 12 × 88% occupancy rate. Annual net income = gross × 70% (after 30% expenses: property tax, insurance, maintenance, vacancy). Value added = median home value × 28% uplift (regional ADU comparables). Total return = net income × years + value added. Break-even = total build cost ÷ annual net income. Consult a licensed financial advisor before investing.

Local Zoning Rules
2026 University Place ADU Rules
University Place's 2026 ADU ordinance caps new units at 1,000 sq ft and 24 ft of height — in the typical range most ADU floor plans are designed around. Setbacks run 5 ft side and 5 ft rear, close to the regional baseline. Because of University Place's Seismic Design Category D1 classification, structural drawings for a detached ADU here need a licensed engineer's stamp — architectural sheets for a code-compliant unit under the size cap generally don't.
Permit fees run $2,800–$9,500 — in line with what most homeowners budget for permitting, and plan check takes about 9 weeks at Planning & Development Services. Submit directly to the department online — link below.
