California Civil Code Section 1938 provides that "[a] commercial property owner or lessor shall state on every lease form or rental agreement executed on or after July 1, 2013, whether the property being leased or rented has undergone inspection by a Certified Access Specialist (CASp), and, if it has, whether the property has or has not been determined to meet all applicable construction-related accessibility standards pursuant to [Civil Code] Section 55.53." Does this law apply to lease amendments? The California Commission on Disability Access ("CCDA") position is that the disclosure is required with respect to a lease amendment/renewal of a lease entered into prior to July 1, 2013 and amended/renewed after July 1, 2013. 

Civ. Code Section 1938 does not require that a CASp inspection be undertaken; it only requires disclosure as to whether or not a CASp inspection has been completed and, if it one has been undertaken, whether the property being leased meets applicable accessibility standards. Civil Code Section 55.53(f) provides protection against a plaintiff using the disclosure as evidence against you if you decide to not undertake a CASp inspection by stating that having not done so "shall not be admissible to prove that person's lack of intent to comply with the law."  And there are no express penalties or consequences provided by Civ. Code Section 1938. So why do it? Because it's easy - just add one sentence to the ADA section of your lease - and thereby eliminate the opportunity of a tenant to cite your failure to disclose as a "material non-disclosure" in a dispute over who pays the costs of making ADA repairs triggered by a third party ADA suit.
