   B.   Annexations. Regulations applicable to an area prior to annexation to the city shall continue to apply and shall be enforced by the city until a zone change for the area has been adopted by the city council. The city may, in an ordinance annexing property to the city or ratifying annexation action of the local boundary commission, direct the planning commission to conduct such proceedings as may be necessary to conform the zoning and land use of the property to the requirements of the city's zoning code and Comprehensive Plan.
   C.   Authorization of similar uses. The planning commission may rule that a use, not specifically named in the allowed uses of a zone, shall be included among the allowed uses if the use is of the same general type and is similar to the allowed uses. However, this section does not authorize the inclusion of a use specifically listed in another zone.
   D.   Accessory uses. Accessory uses shall comply with all requirements for the principal use except where specifically modified by this title and shall comply with the following limitations:
      1.   Fences and hedges, uncovered patios, and similar landscaping features may be located within yards but shall not conflict with vision clearance requirements;

      6.   In residential zones, detached accessory buildings shall not exceed one story in height, shall not occupy more than 50 percent of the area of a buildable rear yard, and shall not be closer than 10 feet to each other or to the main building. Accessory buildings shall comply with the appropriate zoning setbacks for front and side yards, as required for the main building and shall maintain a five foot setback from the rear lot line, except that a detached accessory building can be built to the side or rear lot building provided a written mutual agreement of the abutting property owners on the property lines affected be filed with city clerk.

   F.   Reduction of minimum requirements. No lot area, yard or other open space or required off-street parking or loading area existing on or after July 1, 1981, shall be reduced in area, dimension or size below the minimum required by this chapter, nor shall any lot area, yard or other open space or off-street parking or loading area which is required by this chapter for one use be used as the lot area, yard, or other open space or off-street parking or loading area requirement for any other use except as provided in §§ 13.06.200 A. and 13.06.210.
   G.   Public nuisances prohibited. No building, structure, or land shall be occupied or used for any purpose which creates or causes to be created any public nuisance, including but not limited to excessive odor, dust, smoke, cinders, fumes, noise, glare, heat or vibration or any hazard to the general health, safety and welfare as defined by city ordinances, state statutes or by the decisions of any court of competent jurisdiction.
   H.   Enclosure or screening required. 1. Except as otherwise permitted under the conditional use provisions of this chapter, all business, service, repair, processing, storage, or merchandise display shall be conducted wholly within an enclosed building;

   I.   Lot size exceptions. If, on July 1, 198l, a lot or the aggregate of contiguous lots held in a single ownership has an area or dimension which does not meet the lot size requirements of the zone in which the property is located, the lot or aggregate holdings may be occupied by a use permitted outright in the zone subject to the other requirements of the zone and providing, if there is an area deficiency, residential use shall be limited to a single family residence.
   J.   Yard requirement exceptions. 1. Except for that portion of the setback which is listed in subsection 2. herein, the following exception to the front yard requirement for a dwelling is authorized for a lot in any zone. If there are dwellings on both abutting lots with front yards of less than the required depth for the zone, the front yard for the lot need not exceed the average front yard of the abutting dwellings. If there is a dwelling on one abutting lot with a front yard of less than the required depth for the zone, the front yard for the lot need not exceed a depth one-half way between the depth of the abutting lot and the required front yard depth.

Except for occasional tree trunks and poles, these areas shall be maintained without sight obstruction of any kind for a vertical distance of between three and eight feet above ground.
      3.   To permit or afford better light, air and vision on more heavily traveled streets and on streets of substandard width, to protect the streets, and to have the location of structures compatible with the need for the eventual widening of streets, a yard shall be provided abutting streets and portions of streets hereinafter named which shall be the number of feet set forth below in the right hand column, measured at right angles to the center line of the street and, unless otherwise described, measured from the fee title or dedicated right-of-way of the public way:

   K.   Increased or altered street uses. 1. When the city council, the planning commission, or the design review board has before it any application for a land use decision, the decision- making body shall, before granting any change or permit, consider whether the application asks for a change or permit for the alteration or development of property in such a way as to create any likelihood of increased or altered use of any street adjacent to the property. For the purposes of this section, it shall be presumed that any new development of land upon which no structure had previously been built, any alteration of an existing structure adding 20 percent or more to the floor space of the structure and any change in the commercial use of land to a use the decision-making body finds to generate more traffic presents such a likelihood.
      2.   Upon making the finding of a likelihood of increased or altered street use, the decision-making body shall consider whether the dedicated street width at the location is adequate at the time to accommodate both the existing traffic and such traffic as the street may be expected to be required to carry in the foreseeable future, and in making this determination the decision- making body shall consider the planned street width as set forth in the Comprehensive Plan, and this code, and shall not regard as satisfactory any width less than that planned width, except upon a showing of extraordinary circumstances making it clear that the planned street width is inappropriate.
      3.   The decision-making body shall then require that the owner of the land which is subject of the pending application do whichever of the following seems to the decision making body to best meet the needs of the community:
         a.   dedicate as much land as is required to make up the necessary road width; or
         b.   improve the amount of road to standard, as the decision making body may deem necessary; or
         c.   improve to standard one-half the width of the road for as great a distances the decision-making body may deem necessary.
   Except in cases in which immediate whole-street improvement is required, the decision-making body shall also require that the applicant enter into an agreement with the city by which the applicant shall agree that he will not remonstrate against a local improvement district street improvement project upon the affected street, and the city shall agree that the applicant shall be given credit against his portion of the costs of the street improvement project for the land dedicated and for the cost of improving any portion of the street actually improved to standard by the applicant.
      4.   Permits for the construction of single-family dwellings shall be issued only after the city has examined the application for building permit to determine whether the proposed dwelling is to be built upon a street improved to the city standards. The permit shall be given the endorsement of the city, indicating that the street upon which the dwelling is to be built has been so improved. In the event the street upon which the dwelling is to be built has not been improved to city standards, then the endorsement of the city shall be given only upon the applicant's dedicating the land necessary to make up the planned width of the street as set forth in subsection 2. of this section and signing the agreement not to remonstrate, as described in subsection 3. of this section, or if the applicant chooses and the city staff acquiesces, upon the applicant making the appropriate whole-street or half-street improvement.
   L.   Building height limit exceptions. 1. The following types of structures or structural parts are not subject to the building height limitations of this title: chimneys, tanks, church spires, domes, monuments, fire and hose towers, observation towers, masts, aerials, cooling towers, transmission towers, smokestacks, flagpoles, radio and television towers, and other similar projections.
      2.   Building heights in any zone may be increased as a conditional use to a maximum permitted height of 75 feet provided that the total floor area of the buildings does not exceed the area requirement of the zone (if any) and provided that in residential zones all yards shall have a minimum depth of not less than three- quarters the height of the principal structure.
