Commission adopts updated moderate‑income housing strategy, emphasizing ADUs and biennial review

The Utah County Commission approved an updated moderate-income housing plan intended to meet a state code requirement that jurisdictions select strategies to support housing affordable to households at or below 80% of area median income.

Planning staff member Bryce Armstrong walked commissioners through the definition and data underpinning the plan, including HUD-derived estimates: for example, a four-person household at the moderate-income limit might have an annual income near $74,900 and face housing-cost limits of roughly $1,800 per month under the 30%-of-income metric. “State code defines moderate income housing as housing occupied or reserved for occupancy by households with the gross household income equal to or less than 80% of the median gross income,” Armstrong said.

The county selected practical strategies targeted to unincorporated areas where city-style mixed‑use tools are less applicable — notably lowering barriers to accessory dwelling units (ADUs), allowing certain caretaker or limited higher-density options where appropriate, and maintaining participation with the Utah County Housing Authority. Commissioners agreed to update numeric context every two years and approved the staff-recommended ordinance version unanimous voice vote.

The planning office said the ordinance and implementation plan will be revisited biennially and that staff will report on barriers and outcomes as they monitor uptake of ADU and other strategies.
