(A) Accessory Structures Within Residential Districts:
1. Site Development Standards: Except as provided below, all accessory structures, whether attached or detached, shall meet all site development standards applicable to the main structure as required by the zone district in which the main structure is located.
2. Canopies/Patio Covers: Canopies/patio covers or roofs attached to the main building or connecting the main building to an accessory building, may extend into a required rear or interior side yard; provided, that the portions of such structures extending into the yard:
(a) Shall not exceed fifteen feet (15') in height, project closer than thirty inches (30") to an interior side lot line, project closer than thirty inches (30") to a rear lot line where the rear yard setback is five feet (5'), or project closer than five feet (5') to a rear lot line where the rear yard setback is in excess of five feet (5').
(b) Shall be entirely open on at least three (3) sides, excluding the necessary supporting columns; except that a roof connecting a main building and an accessory building shall be open on two (2) sides.
3. Ground Mounted Mechanical Equipment: Ground mounted equipment, including, but not limited to, air conditioning compressors, evaporative coolers and pool equipment, if fully enclosed, may be permitted in any rear or interior side yard setback. If fully enclosed, said equipment may project a maximum of four feet (4') into the required rear yard setback, and a maximum of two feet (2') into the required interior side yard setback, but shall be prohibited from projecting into the required front or street side yard setbacks.
4. Roof Mounted Mechanical Equipment: All roof mounted mechanical equipment, including, but not limited to, air conditioning compressors, evaporative coolers and pool equipment, shall be located, when practical, on the rear portion of the roof ridgeline in such a manner as to be screened from public streets. On commercial property, said mechanical equipment may be placed forward of a ridgeline, provided screening for the equipment has been approved. Industrial property is exempt from this provision.
5. Detached Accessory Structures:
(a) A detached accessory structure may be located within an interior side yard or rear yard; provided, that when such a structure is located closer than five feet (5') to an interior side or rear lot line, one hour firewalls shall be installed on the sides located within the setback area. In no case, however, shall an accessory structure be located closer than thirty inches (30") to an interior side property line or to a rear property line.
(b) Accessory buildings shall have a maximum height of fifteen feet (15'); provided, however, that the accessory building is no higher than the main structure.
6. Projections Into Yards: Porches, steps and other architectural features, such as eaves, awnings, fireplaces, chimneys, balconies, stairways, wing walls and bay windows may project a maximum of thirty inches (30") into any required front, rear or side setback area.
(B) Accessory Structures Within Nonresidential Districts:
1. Location Within Building Frontage Prohibited: In any nonresidential district, accessory structures shall not be located within the "building frontage", as defined in section 6-1-19 of this title.
2. Setback Requirements: In any nonresidential district, accessory structures shall meet all of the setback requirements for the associated main buildings.
3. Encroachments: In nonresidential zone districts, eaves, roof projections, awnings and similar adjacent architectural features may project into the city right of way subject to receiving an approved encroachment permit from the public works director.
4. Architectural Projections: Fireplaces, chimneys, bay windows, balconies, fire escapes, exterior stairs and landings, and similar architectural features, may project into required building setback areas a maximum distance of thirty inches (30"); provided, that all such features in any one setback shall not occupy more than twenty five (25) square feet of that required building setback area.
5. Mechanical Equipment Height: Flues, chimneys, antennas, elevators and other mechanical equipment, spires, bell towers or similar architectural, utility or mechanical features, may exceed the height limit of the land use district in which it is located by not more than twenty five percent (25%); provided, that such feature shall not be used for habitable space and appropriate screening is provided for mechanical equipment when possible.
6. Equipment Screening: Ground and wall mounted equipment incidental to industrial, commercial or office development shall be appropriately screened with solid walls and/or landscaping. Such equipment shall not be located in front of a building and any screening provided shall be architecturally compatible with adjacent architecture and materials.
7. Use Of Roof Mounted Equipment: Roof mounted equipment shall be used only for the building upon which it is mounted.
8. Roof Mounted Equipment Screening: Roof mounted equipment shall be screened from public view to the extent practicable, as follows:
(a) All roof screens must be solid and continuous. Equipment may be covered by continuous grills or louvers, provided such grills or louvers are architecturally compatible with the proposed or existing building.
(b) Roof screens shall be sheathed in a matching or complementary material to the exterior building material and may include metal panels, aluminum, copper, ceramic tile or other surface as approved by the project assistance team.
(c) Mechanical plants and distribution networks shall be located in a manner that is compatible with the affected building. (Ord. 805-14, 7-1-2014)
