Section R105.3.1.1 of the International Residential Code, 2003 Edition, is amended as follows:
R105.3.1.1 Substantially improved or substantially damaged existing buildings in areas prone to flooding. For applications for reconstruction, rehabilitation, addition, or other improvement of existing buildings or structures located in an area prone to flooding as established by Table R301.2(1), the building official shall examine or cause to be examined the construction documents and shall prepare a finding with regard to the value of the proposed work. For buildings that have sustained damage of any origin, the value of the proposed work shall include the cost to repair the building or structure to its predamage condition. If the building official finds that the value of proposed work equals or exceeds 50 percent of the assessed value of the building or structure before the damage has occurred or the improvement is started, the finding shall be provided to the board of appeals for a determination of substantial improvement or substantial damage. Applications determined by the board of appeals to constitute substantial improvement or substantial damage shall meet the requirements of Section R323.
(Ord. 1142(part), 2006)
15.12.040 Amendments to Chapter 1, Section R108, Fees.
Section R108 of the International Residential Code, 2003 Edition, is amended as follows:
R108.1 Payment of fees. A permit shall not be valid until the fees prescribed by law have been paid, nor shall an amendment to a permit be released until the additional fee, if any, has been paid.
R108.2 Schedule of permit fees. On buildings, structures, electrical, gas, mechanical, and plumbing systems or alterations requiring a permit, a fee for each permit shall be paid as required, in accordance with the schedule as established by the applicable governing authority. The fee for each permit shall be as set forth in Amended Table 1-A as established in Section 15.40.020 of the Wapato Municipal Code.
R108.2.1 Plan review fees. When submittal documents are required to be submitted by Section R106, a plan review fee in addition to the permit fee shall be paid at the time of submitting submittal documents for plan review. Said plan review fee shall be SIXTY-FIVE (65) PERCENT of the building permit fee as shown in Amended Table 1-A. The plan review fees specified in this subsection are separate fees from the permit fees specified in Section R108.2 and are in addition to the permit fees. When submittal documents are incomplete or changed so as to require additional plan review, or when the project involves deferred submittal items as defined in Section 106.3.4.2, an additional plan review fee shall be charged at the rate shown in Amended Table 1-A.
R108.3 Building permit valuations. The applicant for a permit shall provide an estimated permit value at time of application. Permit valuations shall include total value of work, including materials and labor, for which the permit is being issued, such as electrical, gas, mechanical, plumbing equipment and permanent systems. If, in the opinion of the building official, the valuation is underestimated on the application, the permit shall be denied, unless the applicant can show detailed estimates to meet the approval of the building official. The determination of value or valuation under any of the provisions of this code shall be made by the Building Official by reference to the “building valuation data” as primed in the “Building Safety” magazine. The value to be used in computing the building permit and building plan review fee shall be the total value of all construction work for which the permit is issued, as well as all finish work, painting, roofing, electrical, plumbing, heating, air-conditioning, elevators, fire extinguishing systems and any other permanent equipment. Final building permit valuation shall be set by the building official.
R108.4 Work Commencing Before Permit Issuance. Any person who commences any work on a building, structure, electrical, gas, mechanical or plumbing system before obtaining the necessary permits shall be subject to a fee established by the building official that shall be in addition to the required permit fees. An investigation fee, in addition to the permit fee, shall be collected whether or not a permit is then or subsequently issued. The investigation fee shall be equal to the amount of the permit fee required by this code. The minimum investigation fee shall be the same as the minimum fee set forth in Amended Table 1-A. The payment of such investigation fee shall not exempt any person from compliance with all other provisions of this code nor from any penalty prescribed by law.
R108.5 Related fees. The payment of the fee for the construction, alteration, removal or demolition for work done in connection to or concurrently with the work authorized by a building permit shall not relieve the applicant or holder of the permit from the payment of other fees that are prescribed by law.
R108.6 Refunds. The building official is authorized to establish a refund policy.

15.12.050 Amendments to Chapter 1, Section R112.1, General.
Section R112.1 of the International Residential Code, 2003 Edition, is amended as follows:
R112.1 General. The board of appeals created in Section 112 of the International Building Code as amended in Yakima County Code 13.05.060 shall hear and decide appeals of orders, decisions or determinations made by the building official relative to the application and interpretation of this code. The building official shall be an ex-officio member of said board but shall have no vote on any matter before the board. The board shall follow the rules of procedure for conducting its business set forth in Section 112 of the International Building Code as amended in Yakima County Code 13.05.060, and shall render all decisions and findings in writing to the appellant with a duplicate copy to the building official.
(Ord. 1142(part), 2006)
15.12.060 Amendments to Chapter 1, Section R112.2.1, Determination of substantial improvement in areas prone to flooding.
Section R112.2.1 of the International Residential Code, 2003 Edition, is amended as follows:
R112.2.1 Determination of substantial improvement in areas prone to flooding. When the building official provides a finding required in Section R105.3.1.1, the board of appeals shall determine whether the value of the proposed work constitutes a substantial improvement. A substantial improvement means any repair, reconstruction, rehabilitation, addition, or improvement of a building or structure, the cost of which equals or exceeds 50 percent of the assessed value of the building or structure before the improvement or repair is started. If the building or structure has sustained substantial damage, all repairs are considered substantial improvement regardless of the actual repair work performed. The term does not include:
1. Improvements of a building or structure required to correct existing health, sanitary or safety code violations identified by the building official and which are the minimum necessary to assure safe living conditions; or
2. Any alteration of an historic building or structure provided that the alteration will not preclude the continued designation as an historic building or structure. For the purpose of this exclusion, an historic building is:
2.1. Listed or preliminarily determined to be eligible for listing in the National Register of Historic Places; or
2.2. Determined by the Secretary of the U.S. Department of Interior as contributing to the historical significance of a registered historic district or a district preliminarily determined to qualify as an historic district; or
2.3. Designated as historic under a state or local historic preservation program that is approved by the Department of Interior.
(Ord. 1142(part), 2006)
15.12.065 Amendments to Chapter 1, Section R112.2, General.
Section R112.2 of the International Residential Code, 2003 Edition, is amended as follows:
R112.2.2 Criteria for issuance of a variance for areas prone to flooding. Variances are interpreted in the National Flood Insurance Program and are based on the general zoning law principle that they pertain to a physical piece of property; that they are not personal in nature and do not pertain to the structure, its inhabitants, economic or financial circumstances. They primarily address small lots in densely populated residential neighborhoods. As such, variances from flood elevations should be quite rare. A variance shall only be issued upon:
1. A showing of good and sufficient cause that the unique characteristics of the size, configuration or topography of the site render the elevation standards in Section R323 inappropriate.
2. A determination that failure to grant the variance would result in exceptional hardship by rendering the lot undevelopable.
3. A determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, extraordinary public expense, nor extreme nuisances, cause fraud on or victimization of the public, or conflict with existing local laws or ordinances.
4. A determination that the variance is the minimum necessary to afford relief, considering the flood hazard.
5. Submission to the applicant of written notice specifying the difference between the design flood elevation and the elevation to which the building is to be built, stating that the cost of flood insurance will be commensurate with the increased risk resulting from the reduced floor elevation, and stating that construction below the design flood elevation increases risks to life and property.
