In Practice
A property in an R-2 zone may be developed with either a single-family home or a two-family dwelling, subject to the zone's setbacks, height limits, and lot coverage standards. The duplex allowance can meaningfully affect both the use and market value of R-2 parcels compared to R-1 properties. As with R-1 zones, state ADU laws in many states allow additional secondary units in R-2 zones beyond what the local designation would otherwise permit.
