   5) Sidewalks and driveways not more than 30 inches (762 mm) above grade and not over any basement or story below and which are not part of an accessible route.

   6) Painting, papering, tiling, carpeting, cabinets, counter tops, and similar finish work.

   7) Temporary motion picture, television and theater stage sets and scenery.

   8) Prefabricated swimming pools accessory to a Group R-3 occupancy, as applicable in Section 101.2, which are less than 24 inches (610 mm) deep, to not exceed 5,000 gallons (18,925 L) and are installed entirely above ground.

   9) Shade cloth structures constructed for nursery or agricultural purposes and not including service systems.

   10) Swings and other playground equipment accessory to detached one- and two-family dwellings.

   11) Window awnings supported by an exterior wall which do not project more than 54 inches (1372 mm) from the exterior wall and do no require additional support of Group R-3, as applicable in Section 101.2, and Group U occupancies.

   12) Movable cases, counters and partitions not over 5 feet 9 inches (1753 mm) in height.

  R105.8 — Responsibility: It shall be the duty of every person who performs work for the installation or repair of building, structure, electrical, gas, mechanical, or plumbing systems, for which this code is applicable, to comply with this code and the New Mexico Construction Industries Licensing Act.

  R107.3 — Temporary Power: The building official is authorized to give permission to temporarily supply and use power in part of an electric installation before such installation has been fully completed and the final certificate of completion has been issued. The part covered by the temporary certificate shall comply with the requirements or power in the NEC.

  R112.1 — General: In order to hear and decide appeals of orders, decisions or determinations made by the building official relative to the application and interpretation of this code, there shall be and is hereby created an appeals process. The Director of Technical Assistance or the Staff of the ICC Opinion Policy will provide the opinion of the ICC in writing, by telephone, or by E-mail. The final authority of code interpretations is the responsibility of the building official.

  R112.2 — Limitations on authority. The process for appeal shall be based on a claim that the true intent of this code or the rules legally adopted thereunder have been incorrectly interpreted, the provisions of this code do not fully apply, or an equally good or better form of construction is proposed.

  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 building official 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 market 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. 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.

 For SI: 1 pound per square foot = 0.0479 kPa, 1 mile per hour = 0.447 m/s.

  a. Weathering may require a higher strength concrete or grade of masonry than necessary to satisfy the structural requirements of this code. The weathering column shall be filled in with the weathering index (i.e., "negligible," "moderate" or "severe") for concrete as determined from the Weathering Probability Map [Figure R301.2(3)]. The grade of masonry units shall be determined from ASTM C 34, C 55, C 62, C 73, C 90, C 129, C 145, C 216 or C 652.

  b. The frost line depth may require deeper footings than indicated in Figure R403.1(1). The jurisdiction shall fill in the frost line depth column with the minimum depth of footing below finish grade.

  c. The jurisdiction shall fill in this part of the table to indicate the need for protection depending on whether there has been a history of local subterranean termite damage.

  d. The jurisdiction shall fill in this part of the table with the wind speed from the basic wind speed map [Figure R301.2(4)]. Wind exposure category shall be determined on a site-specific basis in accordance with Section R301.2.1.4.

  e. The outdoor design dry-bulb temperature shall be selected from the columns of 97½-percent values for winter from Appendix D of the International Plumbing Code. Deviations from the Appendix D temperatures shall be permitted to reflect local climates or local weather experience as determined by the building official.

  f. The jurisdiction shall fill in this part of the table with the seismic design category determined from Section R301.2.2.1.

  g. The jurisdiction shall fill in this part of the table with (a) the date of the jurisdiction's entry into the National Flood Insurance Program (date of adoption of the first code or ordinance for management of flood hazard areas), (b) the date(s) of the currently effective FIRM and FBFM, or other flood hazard map adopted by the community, as may be amended.

  h. In accordance with Sections R905.2.7.1, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1 and R905.8.3.1, where there has been a history of local damage from the effects of ice damming, the jurisdiction shall fill in this part of the table with "YES". Otherwise, the jurisdiction shall fill in this part of the table with "NO".

  i. The jurisdiction shall fill in this part of the table with the 100-year return period air freezing index (BF-days) from Figure R403.3(2) or from the 100-year (99%) value on the National Climatic Data Center data table "Air Freezing Index-USA Method (Base 32° Fahrenheit)" at www.ncdc.noaa.gov/fpsf.html.

  j. The jurisdiction shall fill in this part of the table with the mean annual temperature from the National Climatic Data Center data table "Air Freezing Index-USA Method (Base 32° Fahrenheit)" at www.ncdc.noaa.gov/fpsf.html.
