§ 3.1H SOUNDPROOFING REQUIRED.
   (A)   Soundproofing shall be required for all new residential uses in each of the Noise Overlay Zones. Soundproofing is required and no building permit shall be issued for new single-family, two- family or multi-family dwellings until the builder has demonstrated that the building design is capable of achieving the noise level reduction required in Table 3.1-A, Land Use Compatibility Standards. This requirement can be met in one of two ways as described in the following divisions:
      (1)   Design standards. The builder may choose to use a design that incorporates the design standards described in Article 3.1I, and, if so, the design shall be considered to have met the required soundproofing standard; and
      (2)   Performance standards. The builder may choose to use design features other than those described in Article 3.1I, as long as the final design is capable of achieving the noise level reduction required in Table 3.1-A, Land Use Compatibility Standards. Such noise attenuation capability shall be certified on the building plans by a registered architect, structural engineer, or acoustician.
   (B)   These soundproofing requirements provided for in Articles 3.1H(1) and 3.1H(2) above are not applicable to buildings that have already been issued a building permit on the effective date of this ordinance nor to room additions, garages, storage buildings or commercial buildings.
