[Ord. 97-715B, § 1; Ord. 02-969B, § 1; Ord. 10-1244B, § 2]
The Regional Framework Plan calls for a compact urban form and a “fair-share” approach to meeting regional housing needs. It is the purpose of Title 1 to accomplish these policies by requiring each city and county to maintain or increase its housing capacity except as provided in section 3.07.120.
[Ord. 97-715B, § 1; Ord. 02-972A, § 1; Ord. 02-969B, § 1; Ord. 07-1137A, § 1; Ord. 10-1244B, § 2; Ord. 15-1357]
(a) 
A city or county may reduce the minimum zoned capacity of the Central City or a Regional Center, Town Center, Corridor, Station Community or Main Street under subsection (d) or (e). A city or county may reduce its minimum zoned capacity in other locations under subsections (c), (d) or (e).
(b) 
Each city and county shall adopt a minimum dwelling unit density for each zone in which dwelling units are authorized except for zones that authorize mixed-use as defined in section 3.07.1010. If a city or county has not adopted a minimum density for such a zone prior to March 16, 2011, the city or county shall adopt a minimum density that is at least 80 percent of the maximum density.
(c) 
A city or county may reduce its minimum zoned capacity by one of the following actions if it increases minimum zoned capacity by an equal or greater amount in other places where the increase is reasonably likely to be realized within the 20-year planning period of Metro’s last capacity analysis under ORS 197.299:
(1) 
Reduce the minimum dwelling unit density, described in subsection (b), for one or more zones;
(2) 
Revise the development criteria or standards for one or more zones; or
(3) 
Change its zoning map such that the city’s or county’s minimum zoned capacity would be reduced.
Action to reduce minimum zoned capacity may be taken any time within two years after action to increase capacity.
(d) 
A city or county may reduce the minimum zoned capacity of a zone without increasing minimum zoned capacity in another zone for one or more of the following purposes:
(1) 
To re-zone the area to allow industrial use under Title 4 of this chapter or an educational or medical facility similar in scale to those listed in section 3.07.1340(d)(5)(B)(i) of Title 13 of this chapter; or
(2) 
To protect natural resources pursuant to Titles 3 or 13 of this chapter.
(e) 
A city or county may reduce the minimum zoned capacity of a single lot or parcel so long as the reduction has a negligible effect on the city’s or county’s overall minimum zoned residential capacity.
(f) 
A city or county may amend its comprehensive plan and land use regulations to transfer minimum zoned capacity to another city or county upon a demonstration that:
(1) 
A transfer between designated Centers, Corridors or Station Communities does not result in a net reduction in the minimum zoned capacities of the Centers, Corridors or Station Communities involved in the transfer; and
(2) 
The increase in minimum zoned capacity is reasonably likely to be realized within the 20-year planning period of Metro’s last capacity analysis under ORS 197.299.
(g) 
A city or county shall authorize the establishment of at least one accessory dwelling unit for each detached single-family dwelling unit in each zone that authorizes detached single-family dwellings. The authorization may be subject to reasonable regulation for siting and design purposes.
