The Rent Administrator shall issue a notice of non-compliance when an investigation results in a determination that a failure to comply with an order of the Rent Administrator, Office of Administrative Hearings, or the Commission may have occurred.
An investigation of a possible failure to comply with an order of the Rent Administrator, Office of Administrative Hearings, or the Commission may be conducted for the following reasons:
If an investigation by the Rent Administrator has found substantial grounds to believe that a possible failure to comply with an order may have occurred, a notice of non-compliance shall be prepared and served on the alleged violator.
The notice of non-compliance shall clearly state the section of the order that has allegedly not been complied with, along with a brief statement of the substantial evidence found during the investigation that supports the determination that a failure to comply has occurred.
A notice of non-compliance shall be served on the alleged violator in accordance with the service of notice provisions under § 3911 and shall contain a statement providing the alleged violator with fifteen (15) days to reply to the notice of noncompliance.
If the alleged violator fails to demonstrate compliance or reply to the notice of non-compliance within fifteen (15) days of receipt of the notice of noncompliance, the Rent Administrator shall immediately refer the matter to the Office of the Attorney General for appropriate enforcement or to the Department of Buildings or Department of Licensing and Consumer Protection, as applicable.
