Frank is correct...the statute was signed into law by the President, but it will be some time before the regulations implementing the law are in effect. First, the HUD must draft the proposed regulations to implement the law and publish it in the Federal Register - . https://www.federalregister.gov/. The public has the opportunity to review and comment on the proposed regulations.[Notice and comment period are generally 30-60 days - however for complex issues it can be up to 180 days] Then HUD has to review, and consider all the comments and then publish the proposed final regulations in the Federal Register. This may take more than a year - especially in a year where the administration changes. The Final Rule will also have an effective date and the local HUD office will probably learn of the new regulations shortly before the effective date.
It would behoove park owners to review the proposed regulations and, if appropriate, comment on the proposed regulations. Of course HUD may be interested in obtaining information from the industry regarding the regulations. So the industry trade associations may be asked for information.
