(2) For purposes of the filing of petitions for adjustments in the rent charged as prescribed in § 42-3502.16, the housing accommodation and each of the rental units in the housing accommodation shall have been inspected at the request of each housing provider by the Department of Buildings within the 30 days immediately preceding the filing of a petition for adjustment.
(c) A tenant of a housing accommodation who, after receipt of not less than 5 days written notice that the housing provider desires an inspection of the tenant’s rental unit for the purpose of determining whether the housing accommodation is in substantial compliance with the housing regulations, refuses without good cause to admit an employee of the Department of Buildings for the purpose of inspecting the tenant’s rental unit, or who refuses without good cause to admit the housing provider or the housing provider’s employee or contractor for the purpose of abating any violation of the housing regulations cited by the Department of Buildings, will be considered to have waived the right to challenge the validity of the proposed adjustment for reasons that the rental unit occupied by the tenant is not in substantial compliance with the housing regulations.
(d) Nothing in this section shall be construed to limit or abrogate a tenant’s right to initiate any lawful action to correct any violation in the tenant’s rental unit or in the housing accommodation in which that rental unit is located.
(e) Notwithstanding any other provision of this chapter, no rent shall be adjusted under this chapter for any rental unit with respect to which there is a valid written lease or rental agreement establishing the rent for the rental unit for the term of the written lease or rental agreement.
