Silverton City Zoning Code
§ 153.17
ACCESSORY USE STANDARDS.
(A) Purpose. In addition to the principal uses expressly included in the zoning districts such use types shall be deemed to include such accessory uses which are specifically identified by these accessory use regulations; and such other accessory uses which are necessarily and customarily associated with, and are appropriate, incidental, and subordinate to, such principal uses. When provided by these regulations, it shall be the responsibility of the Zoning Enforcement Officer to determine if a proposed accessory use is necessarily and customarily associated with, and is appropriate, incidental, and subordinate to the principal use, based on the Zoning Enforcement Officer's evaluation of the resemblance of the proposed accessory use to those uses specifically identified as accessory to the principal uses and the relationship between the proposed accessory use and the principal use.
(B) Zoning permit required. Unless otherwise expressly stated, a zoning permit shall be required for the construction or establishment of an accessory use or structure.
(C) Accessory use standards. In all districts, except as specified in each district, accessory uses and structures shall be subject to the following requirements:
(1) No accessory building or use shall be constructed or established prior to the start of construction of the principal building or use to which it is accessory.
(2) Accessory structures shall be located on the same parcel for which the principal structure is found and shall be in compliance with the following requirements:
(a) In all residential districts, an accessory building shall not be located closer than three feet to a rear or side lot line.
(b) In all non-residential districts, an accessory building shall not be located closer than ten feet to a rear or side lot line when abutting any residential use or residential zoning district. When an accessory use abuts a non-residential use or zoning district, there shall be no side yard or rear yard setback requirements for an eligible accessory use.
(3) An accessory building shall not be located within a front yard or side yard in any residential zoning district. An accessory building or structure shall not be located in the front yard of any non-residential zoning district.
(4) No accessory building shall be located closer than six feet to the principal building.

In no case shall any ornamental feature more than two and one-half feet in height above the curb level be located so as to block the sight distance at street or drive intersections within the designated "No Accessory Structure Zone". In the case of a street intersection, the sight triangle shall consist of the area between points 35 feet from the right-of-way line along both intersecting streets.
(3) Decks and stoops. Porches, balconies, decks and stoops which are uncovered, may extend into any yard, provided that such projections shall not extend into a front yard more than eight feet. Stoops may extend into a side yard not more than two feet.
