South Byron sits in rural Genesee County, where 136 residents spread across less than half a square mile rely almost entirely on PO Box service. The post office maintains 48 boxes for 53 occupied households, giving this community an adoption rate of 91%. That's not typical in New York, where street delivery dominates most areas.
The explanation is simple: rural carrier routes serve the scattered homes along Route 237, Mechanic Street, and East Main Street. There's no city-style delivery here. Residents either collect mail from boxes or receive it via two rural routes that cover the area. The median household income sits at $34,172, and the median home value reaches $111,100. Most residents work traditional jobs, with none reported working from home in recent census surveys.
The street network centers on Route 237, a numbered state highway that forms the spine of this rural hamlet. Mechanic Street and East Main Street represent the traditional small-town grid, though with minimal development. The presence of a Postmaster building entry suggests the post office serves as a community anchor point.
