Gunnison council lowers minimum lot-width thresholds to encourage infill, keeps area requirements

The Gunnison City Council on June 17 adopted a zoning code amendment that reduces minimum lot-width requirements for single-family properties to encourage infill while preserving existing area and setback standards.

City staff described the amendment as clarifying how the city measures frontage and lot width and said the planning commission recommended lowering the frontage requirement in certain zones so older, legally created smaller lots can be developed without losing the area minimums. "We have over 100 lots in the R2 zone that have less than a 100 feet of width... allowing the single-family lots to be reduced from 100 to 70" will enable more infill opportunities, Dennis told the council.

Under the change, single-family lot width in R2 will drop from 100 to 70 feet and corporate lot minimums will move from 120 to 90 feet; the intrinsic area requirement (for example the 10,000-square-foot standard in R2) remains in place. Staff said the amendment preserves setbacks and does not alter maximum building envelopes beyond those existing controls.

Council members discussed grandfathering, the potential for lot splits and the existing large-lot subdivision process; staff noted that legally created lots that do not meet prior width standards could proceed under the revised measurements. The ordinance passed on a 3–1 vote with one council member opposed.

The amendment is intended to ease development on older, narrower lots in established neighborhoods without changing the city's area minima or setback protections. Council asked staff to monitor outcomes and report back if the change produces unintended subdivision patterns.
