Expiration and Renewals

A mobile home park registration expires one year from the first day of the following month after the Division of Housing approves the park’s registration application. See 8 CCR 1302-15, Rule 2.5.

The division will not accept renewals more than 60 days before an expiration date.



The division approves a park registration in January 2024. That registration expires February 1, 2025. If the landlord is still operating the land as a mobile home park one year later, they must renew the registration between December 3, 2024 and January 31, 2025. 

If the land isn’t a mobile home park anymore, the landlord needs to request not to be required to register.


Staff send an information packet to landlords 60 days before the registration expires. Landlords should pick up any certified mail they receive from the Department of Local Affairs or the Division of Housing. Also, if the primary contact for the park has an email address, they will receive reminder emails 60, 30, and 14 days before the registration expires.


The due dates depend on the park’s status. 

  • Currently registered parks must register no later than 11:59 pm Mountain Time (MT) on the last day before the park’s current expiration date. 
  • Parks that were established before the first registration deadline of February 1, 2020 but still haven’t registered must register as soon as possible. See the dates in the penalty notice letters.
  • New parks must register no later than 11:59 pm MT on the last day of the three-month period after mobile home lots became available for rent.

Parks that don’t have an active registration or have outstanding registration penalties can’t increase rent. Find out how to increase rent for mobile home parks.
