County may lift housing-mitigation exemption cap to 3,000 square feet
On June 1, the Planning Commission will weigh AMD2026-0003, a countywide LDR change that would raise the size threshold for exempt single-family homes and ARUs from 2,500 to 3,000 square feet before affordable workforce housing mitigation applies.
If you are building a modest house or an ARU out in the county, pay attention Monday night. The Planning Commission is set to take up AMD2026-0003, a Land Development Regulations text amendment that would increase the affordable workforce housing mitigation exemption size from 2,500 to 3,000 square feet for detached single-family homes and accessory residential units, countywide. Staff is recommending approval. See: Planning Commission Staff Report, AMD2026-0003.
This is a legislative call, not a single permit, so the question for the commission is whether that 500 square foot bump is the right line in the sand for when mitigation kicks in. Staff frames it as a consistency update across LDR sections, and as an attempt to keep local rules lined up with the state’s 3,000 square foot fast-track permitting threshold that takes effect July 1, 2026. If the commission recommends approval, the decision still goes on to the county commissioners for final action.
