Council continues review of accessory-building rules after lengthy public hearing

Mapleton City Council continued consideration of proposed changes to accessory-building standards after an extended public hearing in which neighbors raised concerns about privacy, "dead space" behind tall outbuildings, and the potential for residential structures to be used for commercial storage.

Planning staff explained the proposed standards recommended by the Planning Commission: accessory buildings under 15 feet tall would retain the current 3-foot side/rear setback; buildings 15 to 18 feet tall would require at least a 10-foot side/rear setback; and for each additional foot above 18 feet the rear setback would increase by 2 feet until meeting the zone—s rear setback (typically 25 feet). The commission also recommended allowing up to 30% rear-yard coverage for structures 18 feet or less (one story) and reducing coverage to 20% for structures above 18 feet.

Residents at the hearing described how tall outbuildings close to lot lines can create unusable "dead" space in rear yards, reduce privacy, and raise theft or security concerns if storage is pushed away from homes. Benjamin Hickman said he was "looking at building one of these buildings. My neighbor just built one ... now I'm gonna be 25 feet in the middle of my yard. So, I kinda have an issue with that." Lisa Hickman described large rear windows facing the neighborhood and said a tall building would make much of her yard unusable. Sherry Kilpak urged the council to require higher exterior standards, noting that some metal pole barns in residential neighborhoods can be visually jarring.

Council members discussed competing goals: protecting individual property-rights while limiting negative impacts on neighbors. Several council members asked staff to research comparable ordinances in other cities, examine maximum heights and coverage rules, and consider whether commercial uses should be controlled by conditional-use permits. Staff said enforcement can be pursued if a permitted accessory building is later used for commercial purposes, but initial permits are issued on the applicant—s representation of residential use.

After council discussion, Council Member Egbert moved to continue the item for further research and public input; Council Member Reid seconded the motion. The council voted unanimously to continue the matter, and staff was directed to return with additional analysis, comparisons to other jurisdictions, and possible design guidance or limiting language. Members suggested a workshop to refine options before another public hearing.
