¹ The minimum lot size standards apply as established by Sections 1012 and 1107. Notwithstanding the minimum lot size standard, a lot of record may be developed subject to other applicable standards of this Ordinance, except minimum lot size standards of Section 800 apply.

² In a planned unit development, there is no minimum individual lot size. However, the minimum average lot size is one acre except for lots to be developed with a duplex, in which case the minimum average lot size is two acres. The average lot size is calculated by determining the lot area of the land proposed for subdivision, partition, or replat and dividing by the number of lots or parcels in the proposed planned unit development.

³ The minimum lot size inside the Portland Metropolitan Urban Growth Boundary is 20 acres. The 20-acre minimum lot size is applicable to subdivisions, partitions, and Type II replats, but not to Type I replats or property line adjustments. Where this standard applies, it supersedes any other minimum lot size standard in Table 316-2.

⁴ For the purpose of complying with the minimum lot size standard, lots with street frontage on County or public road rights-of-way may include the land area between the front lot line and the centerline of the County or public road right-of-way.

⁵ The minimum lot size inside the urban growth boundaries of the cities of Canby, Estacada, Molalla, and Sandy is five acres.

⁶ The average lot size is calculated by determining the lot area of the land proposed for subdivision, partition, or replat and dividing by the number of lots or parcels in the proposed partition, subdivision, or replat.

⁷ In a planned unit development, the minimum individual lot size is two acres, except inside the urban growth boundaries of the cities of Canby, Estacada, Molalla, and Sandy, where the minimum individual lot size is five acres. In all cases, the minimum average lot size is 10 acres. The average lot size is calculated by determining the lot area of the land proposed for subdivision, partition, or replat and dividing by the number of lots or parcels in the proposed planned unit development.

⁸ In a planned unit development, the minimum front setback is 20 feet.

⁹ For a corner lot located above 3,500 feet in elevation, one of the minimum front setbacks is 10 feet, except 20 feet to garage and carport motor vehicle entries.

¹⁰ In a planned unit development, there are no minimum rear and side setbacks except from rear and side lot lines on the perimeter of the final plat. Where this standard applies, it supersedes any other rear or side setback standard in Table 316-2.

¹¹ The minimum rear setback for an accessory building shall be five feet except as established by Note 10.

¹² The minimum rear setback for an accessory building shall be 10 feet except as established by Note 10.

¹³ The minimum side setback for an accessory building shall be five feet except as established by Note 10.
