The Bellingham Planning Commission held a public hearing on proposed updates to the city's Accessory Dwelling Unit (ADU) ordinance, designed to bring Bellingham into full compliance with Washington State House Bill 1337. The commission unanimously approved the ordinance with three key amendments after extensive technical discussion about development standards, floor area ratios, and utility sharing provisions. The proposed changes eliminate owner occupancy requirements for ADUs, remove several design standards deemed more restrictive than those applied to primary units, and integrate ADUs more fully with the city's middle housing framework under HB 1110. The Planning Commission's amendments focused on reducing setback requirements, preserving shared utility options, and eliminating minimum parking requirements for ADUs. Staff presented dramatic growth data showing ADU permits increasing from mid-40s annually to over 100 permits after the 2023 implementation of HB 1337 provisions, demonstrating significant pent-up demand for this housing type. The ordinance now moves to City Council with Planning Commission recommendation for approval, with a scheduled hearing on October 20th.

**Floor Area Ratio (FAR) Integration** The commission extensively discussed the transition from square footage limits to FAR calculations for ADUs. Staff explained that FAR provides scalable development standards that work across different lot sizes, promoting housing diversity while maintaining neighborhood compatibility. Commissioner concerns centered on FAR being "wonky" and hard for property owners to understand, but staff emphasized its importance for consistent application across various housing types. The change eliminates ADU exemptions from FAR to align with middle housing standards under HB 1110. **Property Line Setbacks** Staff requested specific guidance on whether detached ADUs should be allowed at zero setback in rear yards, consistent with current accessory building standards. The discussion balanced practical construction needs, neighbor relationships, and regulatory simplicity. Commissioners ultimately supported eliminating the neighbor consent requirement, preferring clear, objective standards over case-by-case negotiations. Fire code requirements and construction …

**Blake Huddle, on development options:** "With all of the new changes at the state level, at the local level, it's almost the question that consultants and people are asking, even us at the counter, when they come in and say, 'What can I do with my lot?' It's more like, 'What can't you do with your lot now?'" **Commissioner Lathrop, on shared utilities:** "We were able to because they were ADUs share utilities. They almost didn't let us. The inspector came out and was like, 'No, we need two …

## Meeting Overview On October 9, 2025, the Bellingham Planning Commission convened at 6:00 PM in City Council Chambers for a public hearing on updates to the City's Accessory Dwelling Unit (ADU) ordinance. This was no routine meeting—the commission was deliberating on sweeping changes required by state law that would fundamentally alter how ADUs can be built in Bellingham. Five commissioners were present: Chair Mike Estes, Dan Bloemker, Jed Ballew, Lisa Marx, and Rose Lathrop. Jerry Richmond and Russ Whidbee were absent. The meeting centered on a critical deadline: Washington State's House Bill 1337, along with companion bills HB 1110 and HB 1293, must be fully implemented by December 31, 2025, or the state will preempt local regulations entirely. This was Bellingham's final opportunity to craft its own approach to ADU reform while meeting state mandates for dramatically expanding housing options. What made this meeting particularly significant was its coordination with the city's broader housing transformation. The ADU changes weren't happening in isolation—they were being harmonized with interim middle housing regulations that allow up to four units per lot (or six with affordability components), creating what staff described as nearly infinite development options that have shifted the conversation from "what can you build?" to "what can't you build?" ## The State Housing Mandate Context Blake Wagner, representing Planning and Community Development, opened the substantive discussion by placing the ADU updates within Washington's historic housing push. "In the 2023 state legislative session, there were several housing bills that came through that session that had particular timelines associated with them," he explained. House Bill 1337 was just one piece of a comprehensive state strategy to address Washington's housing crisis by forcing local governments to remove barriers to alternative housing forms. The urgency was palpable. Originally, cities had six months after comprehensive plan adoption to complete these regulations. "Then in this year's legislative session, they took that …

### Meeting Overview The City of Bellingham Planning Commission held a public hearing on October 9, 2025, to review proposed updates to the Accessory Dwelling Unit (ADU) ordinance. The amendments are required to bring Bellingham into full compliance with Washington State House Bill 1337, which mandates changes to ADU regulations by December 31, 2025. The commission voted 5-0 to recommend approval with several amendments. ### Key Terms and Concepts **ADU (Accessory Dwelling Unit):** A second residential unit on the same property as a primary home, either attached to or separate from the main house. **House Bill 1337:** 2023 Washington State legislation requiring cities to ease barriers to ADU construction by eliminating certain restrictions like owner occupancy requirements and overly restrictive design standards. **Floor Area Ratio (FAR):** A zoning tool that limits building size based on lot size, ensuring development scales appropriately with the property rather than using fixed square footage limits. **Middle Housing (HB 1110):** State legislation allowing up to 4-6 housing units per lot, which ADUs now count toward under the updated regulations. **Type I Review Process:** An administrative approval process that doesn't require public notice, making ADU permits faster and less expensive to obtain. **Principal Unit:** The main dwelling on a property (single-family home, duplex, triplex, etc.) that an ADU is associated with. **Detached ADU (D-ADU):** An ADU in a separate building from the primary residence, such as a converted garage or purpose-built structure. **Minor Modifications:** Small adjustments to development standards that can be approved administratively without requiring a full variance process. ### Key People at This Meeting | Name | Role / Affiliation | |---|---| | Mike Estes | Planning Commission Chair | | Dan Bloemker | Planning Commissioner | | Rose Lathrop | Pl…
