Florence Planning Commission defers proposal to allow detached accessory dwelling units for more review

Florence City planning staff presented a draft amendment to the Unified Development Ordinance to permit detached accessory dwelling units (ADUs), and the Planning Commission voted to defer action to the next meeting to allow more public and commissioner review.

Staff outlined a draft that would allow detached ADUs through a conditional‑use permit with roughly 21 conditions intended to limit impacts on neighbors. The proposal would permit one ADU per lot, require owner occupancy in either the principal unit or the ADU, and cap the detached ADU at 50 percent of the principal structure’s footprint or 800 square feet, whichever is less. The draft would require one improved parking space for an ADU and prohibit separate utility meters; ADUs would also keep the same street address as the principal dwelling.

Planner Miss Lund summarized the staff position and urged commissioners to weigh the changes carefully: “I would like to have everyone take a close look at that and think about it,” Lund said, noting the goal of enabling existing housing stock while controlling impacts on nearby properties.

Commission discussion focused on standards and neighborhood impacts. Commissioners asked how ADU size would relate to the principal house, how parking and impervious-surface rules would apply, and whether tiny-house slab-built units would qualify. Staff confirmed the size cap and said the proposal aims to allow compatible conversions and limited new detached structures while avoiding separate subdivisions or utility splits.

Commissioners also emphasized owner-occupancy as a key control. As one commissioner noted, requiring an owner to live on-site allows the property owner to “keep an eye on who they're renting to,” a point staff cited as a reason other cities adopt similar rules.

Several commissioners said the draft is substantial and warrants more time for study. At the meeting, a commissioner moved to defer the item to next month so commissioners could review the questionnaire and the proposed conditions in detail; the motion to defer carried by voice vote.

The staff packet included a public-support letter submitted earlier in the day and a staff‑compiled list of questions and considerations for commissioners. Staff said that after the commission’s additional review, a revised draft and public‑notice materials would be prepared for the next meeting.

The commission’s deferral does not change the content of the current draft; rather, it postpones action so commissioners and the public can provide input and the commission can consider potential revisions.
