or loss. C. Plan Acceptance. 1. The Department shall make a determination regarding the adequacy of a landlord’s Tenant Habitability Plan within five working days of the Department’s receipt of the plan for review. The Department shall accept those plans which meet the requirements of Subsection B. of this section and which it determines, with reference to the standards set forth in California Civil Code Section 1941.1 and in accordance with any regulations or guidelines adopted by the Commission, will adequately mitigate the impacts of Primary Renovation Work and any Related Work upon tenants. The Tenant Habitability Plan may allow for the temporary disruption of major systems during the hours of 8:00 a.m. to 5:00 p.m., Monday through Friday, without requiring the relocation of tenants in order to adequately mitigate the impacts upon the affected tenants. However tenants should not be exposed at any time to toxic or hazardous materials including, but not limited to, lead-based paint and asbestos. 2. The Department’s acceptance of a Tenant Habitability Plan shall be subject to the landlord having no outstanding balances due for rent registration or code enforcement fees. 3. The Department shall provide landlords with written indications of deficiencies which must be addressed whenever a Tenant Habitability Plan is determined to be inadequate. A landlord may submit an amended plan in order to correct identified deficiencies. 4. Landlords and tenants may appeal the Department’s determination regarding a Tenant Habitability Plan to a hearing officer. The appeal shall be made in writing, upon appropriate forms provided by the Department, and shall specify the grounds for appeal. The appeal shall be filed within 15 calendar days of the service of the Department’s determination, as required by Section 152.04 of this Code and shall be accompanied by the payment of an administrative fee of $35.00. The requested hearing shall be held within 30 calendar days of the filing of the appeal following the procedures set forth in Section 151.07 A.3. of this Code. The hearing officer shall issue a written decision within ten calendar days of the hearing on the appeal, with a copy of the decision served on the landlord and the tenants by first class mail, postage prepaid, or in person.
