(2) A local government shall allow affordable housing, and may not require a zone change or conditional use permit for affordable housing on property if: (a) The housing is owned by: (A) A public body, as defined in ORS 174.109; or (B) A nonprofit corporation that is organized as a religious corporation; or (b) The property is zoned: (A) For commercial uses; (B) To allow religious assembly; or (C) As public lands. (3) Subsection (2) of this section: (a) Does not apply to the development of housing not within an urban growth boundary. (b) Does not trigger any requirement that a local government consider or update an analysis as required by a statewide planning goal relating to economic development. (c) Applies on property zoned to allow for industrial uses only if the property is: (A) Publicly owned; (B) Adjacent to lands zoned for residential uses or schools; and (C) Not specifically designated for heavy industrial uses. (d) Does not apply on lands where the local government determines that: (A) The development on the property cannot be adequately served by water, sewer, storm water drainage or streets, or will not be adequately served at the time that development on the lot is complete; (B) The property contains a slope of 25 percent or greater; (C) The property is within a 100-year floodplain; or (D) The development of the property is constrained by land use regulations based on statewide land use planning goals relating to: (i) Natural disasters and hazards; or (ii) Natural resources, including air, water, land or natural areas, but not including open spaces or historic resources. (4) A local government shall approve an application at an authorized density level and authorized height level, as defined in ORS 227.175 (4), for the development of affordable housing, at the greater of: (a) Any local density bonus for affordable housing; or (b) Without consideration of any local density bonus for affordable housing: (A) For property with existing maximum density of 16 or fewer units per acre, 200 percent of the existing density and 12 additional feet; (B) For property with existing maximum density of 17 or more units per acre and 45 or fewer units per acre, 150 percent of the existing density and 24 additional feet; or (C) For property with existing maximum density of 46 or more units per acre, 125 percent of the existing density and 36 additional feet. (5)(a) Subsection (4) of this section does not apply to housing allowed under subsection (2) of this section in areas that are not zoned for residential uses. (b) A local government may reduce the density or height of the density bonus allowed under subsection (4) of this section as necessary to address a health, safety or habitability issue, including fire safety, or to comply with a protective measure adopted pursuant to a statewide land use planning goal. Notwithstanding ORS 197.350, the local government must adopt findings supported by substantial evidence demonstrating the necessity of this reduction. [2021 c.385 §1]
