North Bend planners review new unit‑lot subdivision and residential lot‑split rules

The North Bend Planning Commission met June 3, 2026, to review staff‑draft unit‑lot subdivision rules and a new residential lot‑split process intended to implement recent state legislation aimed at making housing development simpler and more flexible. Staff said the two related changes would let cities allow flexible internal lot standards while preserving perimeter setbacks and overall density limits.

Staff member Caitlyn summarized the unit‑lot concept as a way to treat an entire “parent lot” as the basis for bulk and dimensional standards while creating individually owned unit lots inside it, which can be useful for cottages, townhouses and certain ADU configurations. Caitlyn said the proposal follows state guidance that short‑plat unit‑lot subdivisions up to nine units must be allowed under the short‑plat (administrative) process; allowing the unit‑lot flexibility for subdivisions larger than nine lots would instead trigger subdivision review before a hearing examiner.

Why it matters: Commissioners said the rules could help homeowners and small developers create more compact, tree‑friendly layouts without increasing overall density. Several commissioners emphasized that the public‑notice and hearing protections that come with subdivision review for projects over nine units remain important for neighborhood awareness.

Key details and questions raised

- Single‑family zones: Staff asked whether the commission wants to allow unit‑lot subdivisions in zones normally limited to single‑family homes. Several commissioners said they were open to allowing such clustering so long as the underlying zone’s density and perimeter setbacks are preserved; others asked for more analysis and clearer language before deciding.

- ADUs: Staff clarified ADUs remain a separate regulatory path but noted limited circumstances where an ADU could be condominiumized or occupy its own unit lot; ADU rules and unit‑lot rules are not identical and density caps still apply.

- Short‑plat cap and public hearing: State law ties short‑plat administrative review to nine units. The commission discussed keeping the nine‑unit administrative threshold and requiring a hearing examiner process for larger projects so the public can comment during the subdivision review.

- Parking and traffic: Staff said on‑street parking is governed by street standards and unit‑lot projects must provide required off‑street parking either on unit lots or on a parent lot. Staff noted a traffic (concurrency) analysis is required when a development exceeds the city’s peak‑hour trip threshold.

- Frontage improvements for lot splits: For the proposed residential lot‑split (new chapter 17.22), staff explained the intent is to streamline dividing a single lot into two and to allow staff discretion to defer or exempt frontage improvements on the existing parent lot, placing the obligation on the newly created lot or its future builder. Commissioners expressed concern that shifting costs to buyers could reduce affordability and produce piecemeal infrastructure; options discussed included establishing a frontage‑length threshold to determine when improvements are required and exploring municipal or special‑district funding as alternatives.

- Five‑year limit: Staff noted state rules include a five‑year limit on further division to prevent circumvention of subdivision review (the commission asked that the limit be clearly stated in the draft language).

Next steps: Staff will return to the commission with proposed ordinance language and diagrams for a public hearing at the next meeting. Commissioners asked staff to consider a frontage‑length threshold and to coordinate recommended thresholds with the city engineer.

The meeting closed with staff saying the items would be revised for a public hearing in the next meeting cycle.
