The Longmont Police Department is committed to fostering a partnership with the businesses and residential dwellings in our community as a means of ensuring public safety. We believe that the Trespass Program increases our ability to better address quality of life issues within the community. It is by working together to make our community safer that we achieve our common goals.

NOTE: This is a voluntary program. Multi-family properties, businesses and HOAs may participate, but only common areas are covered; the individual residential units are not (i.e., individuals actively invited to visit a tenant).

Trespass Law
