R-2 Zoning

R-2 zoning typically allows two-family dwellings — most commonly duplexes — in addition to single-family homes, representing a meaningful step up in residential density from the R-1 classification. The ability to place two units on a single lot increases housing supply while maintaining a physical scale broadly similar to single-family neighborhoods. Lot coverage allowances and other development standards are generally somewhat more permissive in R-2 than in R-1, reflecting the higher unit yield the zone is designed to support.

Zoning

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.
