Which of the following changes requires PHA approval for new tenancy or a new HAP contract?

The correct answer is that all of the changes listed require Public Housing Authority (PHA) approval for new tenancy or a new Housing Assistance Payment (HAP) contract.

When any of these changes occur, they can significantly impact the agreement and the housing assistance being provided. A change in tenant lease terms can alter the rights and responsibilities of tenants and landlords, which directly affects the terms of the HAP contract. Similarly, a change in the rental agreement duration may influence the length of time that assistance is provided, necessitating PHA review to prevent any potential conflicts with program rules. Lastly, modifications in utility payment responsibilities can shift the financial obligations of either the tenant or the landlord, thus impacting the overall viability of the housing arrangement under the HCV program.

Since all of these factors can impact both the tenant's housing stability and the PHA's ability to manage its resources and relationships with landlords, PHA approval is necessary for changes to ensure compliance with HUD guidelines and to maintain the integrity of the Housing Choice Voucher program.
