All residentially zoned areas within the city limits that currently allow single-family homes will be affected. In Eugene, this includes the following zones: R-1 Low Density Residential, R-2 Medium Density Residential, R-3 Limited High Density Residential, R-4 High Density Residential, and certain Special Area Zones (including Chambers, Chase Node, Downtown Westside, Elmira Road, Historic Blair, Jefferson Westside, Royal Node, Whiteaker, and Walnut Station special area zones). Land that is not zoned for residential use, including but not limited to commercial, industrial, agricultural and public land are not affected. In addition, land that is outside of the city limits (not annexed) is also not affected by HB 2001 (but will be, once inside the city limits).
