§ 27-2152 Enforcement.
a. If the commissioner has reasonable cause to believe that an owner has violated the provisions of subdivision a of section 27-2151, the commissioner shall serve a notice of violation and an order to correct such violation on the owner pursuant to sections 27-2091 and 27-2095 of this code. The order shall require the owner to comply with subdivision a of section 27-2151 in the manner specified in such order within ten days. A copy of the order shall be filed with the city register and any subsequent purchaser of the property shall be subject to such order.
b. An owner may apply within the ten day period following service of the notice and order:
1. for the revocation of the notice of violation and order on the ground that the condition alleged to constitute the violation did not exist at the time the violation was placed. The department may grant such revocation upon the presentation of proof satisfactory to the department; or
2. for an extension of the time for correction. The department may, upon good cause shown, including consideration of the complexity of repairs which may be necessary to make the dwelling unit habitable, grant such extension for such period of time that it deems appropriate.
