The recipient can use up to 20 percent of its annual grant amount for administration and planning. The recipient shall identify the percentage of grant funds which will be used in the IHP. HUD approval is required if a higher percentage is requested by the recipient. When HUD approval is required, HUD must take into consideration any cost of preparing the IHP, challenges to and collection of data, the recipient's grant amount, approved cost allocation plans, and any other relevant information with special consideration given to the circumstances of recipients receiving minimal funding.
