Delaware Code Title 25. Property § 7018. Rules

(a) A landlord may promulgate reasonable written rules concerning the occupancy and use of the premises and the use of the landlord's property, and concerning the behavior of manufactured home community tenants, residents, guests, and visitors, provided that the rules further any of the following purposes:

(b) A landlord may not arbitrarily or capriciously enforce a rule.  A landlord may choose not to enforce a rule based upon the documented special needs or hardship of a tenant or resident without waiving the right to the later enforcement of the rule as to that tenant or resident or any other tenant or resident.

(c) A landlord may amend an existing rule at any time, but the amended rule is not effective until the date specified in the amended rule or 60 days after the landlord delivers to the tenant written notice of the amended rule, whichever is later.
