1 Del. Admin. Code § 202 § 4.0

4.1 A community owner is required to give written notice to each affected home owner, to the Home Owners Association, if one exists, and to the Authority, at least 90 days prior to any increase in lot rent. When more than one tenant is affected by the rent increase, in lieu of providing the HOA or the Authority with copies of each letter sent to each affected tenant, the community owner shall provide the HOA and the Authority with a summary letter (“Summary Letter”) certifying that written notice has been sent to each affected home owner together with a copy of the form of notice provided, which form must contain the information required hereunder. The Summary Letter shall identify all affected home owners by lot number, name, group or phase. If the affected home owners are not identified by name, the community owner shall make the names and addresses available to any affected home owner, HOA, and the Authority upon request. In any such notice, in addition to the information required to be provided under 25 Del.C. §7043(a), the community owner shall (with respect to each affected home owner) state whether or not the proposed rent increase exceeds the CPI-U and provide the following information:

4.1.1 The current monthly lot rent;

4.1.2 The proposed monthly lot rent;

4.1.3 The CPI-U;

4.1.4 The effective date of the rent increase;

4.1.5 The community owner’s contact information, which shall include the name and mailing address of a representative of the community owner authorized to respond to questions relating to the proposed rent increase and schedule any necessary meetings and/or arbitration proceedings required under the Act; and

4.1.6 If the proposed rent increase exceeds the CPI-U, a recommendation to the Authority of a date, time and place on which the community owner is available to meet with the affected home owners, Home Owners Association, or their representatives, which date must be within thirty (30) days of the date the notice is mailed out.
