H.R. 5099 would authorize the Department of Veterans Affairs (VA) to accept up to five donations of real property such as land or facilities from nonfederal entities for a pilot program to construct VA facilities. Any such donated property would need to meet a requirement for capital improvements that VA had previously identified as necessary to provide services or benefits to veterans. The department could help finance such a project using any amounts that had been appropriated for that project before it entered into an agreement with the nonfederal entity. The bill would prohibit VA from spending any funds from a subsequent appropriation to complete construction of a donated facility or to pay for the use of such a facility once it is complete. The authority to accept such donations would expire five years after enactment of the bill.
