    Sec. 1. A trustee who pursuant to a trust instrument has title to but no beneficial interest in real property, or a managing agent for real property within 10 days after receipt (by such trustee or a beneficiary empowered or an agent authorized to manage and control such property) from an enforcement agency of the initial written notice or complaint of violation of an ordinance, resolution or regulation of a political subdivision of this State relating to conditions or operations of real property affecting health or safety, shall disclose the identity of every owner and beneficiary with an interest in present use and enjoyment to the department or agency of such political subdivision primarily responsible for enforcement of such ordinance, resolution or regulation.
    For residential buildings, if the violation charged has not been corrected within 180 days of notice to the trustee or managing agent, the enforcement agency shall make public the identity of all owners or all beneficiaries disclosed to it by placing such disclosure in a register to be available to the public at reasonable times in the office of the agency. A reasonable charge for the cost of any reproduction requested may be made. Where the violations are subsequently corrected, the agency shall remove the identity of the disclosed owners or beneficiaries from the register.
