Mayfield commission opens review of accessory-building rules and ADUs, raises safety and infrastructure concerns

Unidentified Speaker 1 moved the agenda to review accessory building regulations, noting the town’s current rule that prohibits living quarters in accessory buildings (to avoid two houses on one lot). Unidentified Speaker 4 asked whether the town should consider allowing accessory dwelling units (ADUs) to give young people or relatives a more affordable housing option.

Members discussed technical and safety constraints. Unidentified Speaker 4 and others said setback and fire-safety rules matter if ADUs are allowed: standard practice discussed was 5 feet from property lines with a 2-hour rated wall or 5/8" sheetrock to protect neighboring buildings. A participant noted the county building inspector would likely enforce code, and that the town could adopt additional requirements if it chose to do so.

The commission also considered utility and metering implications. Commissioners discussed separate water meters for accessory units or duplexes, connection fees and whether single ownership multiplexes could be served by a larger meter; concerns were raised about whether small (3/4") meters can support multiple households and about water pressure.

Several members suggested the question should be taken to a broader town meeting or a public hearing because of potential impacts on neighborhood character, parking and narrow local streets. One commissioner noted the council historically resisted smaller lots; others said council composition can change and that a formal ordinance review and public hearing process is required for any change.

The commission did not adopt any ordinance amendments. Members asked staff to compile the relevant ordinances and code language, and to prepare for a future public hearing if the commission decides to pursue changes to accessory-building rules.
