The yards created by required setbacks shall remain unoccupied and unobstructed, except as otherwise permitted in this section or elsewhere within this title:
A. Required setbacks. All required setbacks shall be measured from the structure's greatest architectural projection to the property line or other point of measurement established by this title, unless otherwise specified in this title. The zoning administrator may grant an exception not to exceed one foot to any setback or height standard, upon a showing of undue hardship or extraordinary physical conditions of the property or structure. Above-grade extensions, such as eaves, rain gutters, bay windows and similar above-grade extensions may extend no more than three feet (3') into a required yard.
1. Accessory buildings of two hundred (200) square feet or less shall be permitted in required rear yards where a setback of ten feet (10') from all property lines is maintained. No accessory building shall be located in the required front or side yard area. Front and side yards may be used for parking.
2. Residential accessory structures within the Residential and Suburban zoning districts shall be constructed or placed simultaneously or subsequent to the construction of the dwelling. Exceptions are permitted to allow for storage or tool sheds, gazebos, or other similar structures not greater than two hundred (200) square feet of floor area.
3. An accessory structure may be placed on a separate, contiguous lot from the residence if the lot or parcel is combined for development purposes into one lot, pursuant to paragraph F of this section.
4. The combined floor area square footage for all residential accessory structures shall not be greater than a 1:1 ratio of the combined floor area square footage of the residence(s) on a lot or parcel in the Residential district. (Example: if a residence contains 1,000 square feet of floor area, a garage cannot be larger than 1,000 square feet of floor area.) Accessory structures may be attached or detached. Structures such as tool sheds, greenhouses and other such non-habitable structures that are two hundred (200) square feet or less of floor space and exempt from requirements to obtain a building permit shall not be included in the accessory residential structure calculations.
5. Residential accessory structures shall be limited to the private use by residents of the property and their visitors. Commercial uses, except permitted home occupations, are prohibited with accessory residential structures.
C. Required Space: No space required to make up the required yards for any principal building shall be removed from the lot on which that building is sited by sale, lease or other conveyance.
D. Fences: No fence shall exceed seven feet (7') in height. Fences are subject to the following standards:
1. Exceptions to height may be considered as a special use permit or variance.
2. Fencing exceeding seven feet (7') in height is defined as a structure and is subject to the structure standards of this title and the standards of Title 9, Chapter 1, Building Codes and Regulations.
3. All fencing is subject to other title provisions, such as maintaining clear vision at intersections as provided in section
12-6-10 of this chapter, which may affect placement and height.
4. Fences not exceeding seven feet (7') in height may be located along property lines, except that no fence shall exceed four feet (4') in height within twenty feet (20') of the natural, ordinary, or artificial high water mark of a water body identified on the United States Geological Survey maps, with the exception of seawalls, bulkheads, or breakwater permitted by the state for shoreline protection.
5. Fence height shall be considered the vertical distance from the base of the fence to the highest point on the fence or fence structure, including all caps, finials, posts, lights, latticework, screens, landscaping berms, rockery, bases, or other similar fencing materials or features. Measurement shall be determined from the natural grade of the property at the fence line, prior to development. An arbor serving as a landscaping feature over a gate, walkway or entrance may be permitted to a maximum nine feet (9') in height and four feet (4') in width.
6. Fencing materials such as junk and tires and other such materials and those that pose hazards or safety concerns, such as razor wire or broken glass, are prohibited.
E. Maximum Building Height: The maximum building height is set forth at section
12-6-4 of this chapter. "Building height" is defined at section
12-13-4, appendix D of this title. All proposed structures shall be required to provide with building permit application materials side elevation drawings of all sides of the structure with building height and predevelopment grades depicted. For structures greater than twenty five feet (25') in height, including stem walls, such information shall be certified by an Idaho licensed surveyor, or Idaho licensed engineer, or Idaho licensed architect qualified to establish elevations, and be submitted with building permit application materials. Predevelopment elevations shall be determined by the presence of undisturbed topsoil and/or vegetation or similar indications to the satisfaction of the City. Any costs incurred by the City to determine building height shall be in addition to other building or zoning permit fees and shall be the responsibility of the landowner.
F. Contiguous Properties: Structures may be placed or constructed across parcel or lot lines provided the land is under the same ownership, legally created, and contiguous. The landowner shall record a lot combination agreement stating the land is considered one property for purposes of land development. The land shall be considered one for determination of zoning standards.
G. Placement of a single tram, rail, uncovered steps, stairs or walkway may be within the waterfront setback for bodies of water, as established by this title, provided such structures are not greater than four feet (4') wide and installed to provide access to the shoreline and are generally perpendicular to the shoreline. Boardwalks or other platforms, decks, or similar structures paralleling the shore are prohibited within the waterfront setback area for which the City has jurisdiction.
