Grantees must make reasonable efforts to obtain the cooperation of landlords and utility providers to accept payments from the ERA program. Outreach will be considered complete if a request for participation is sent in writing, by certified mail, to the landlord or utility provider, and the addressee does not respond to the request within 21 calendar days after mailing; or, if the grantee has made at least three attempts by phone or email over a 21 calendar-day period to request the landlord or utility provider’s participation. All efforts must be documented. The cost of the mailing would be an eligible administrative cost.
