Will veteran's assistance pay for a chair lift?

From a section of the VA website:

"Adapted Homes for Disabled Veterans

VA also offers grants to Veterans with certain service-connected disabilities to build an adapted home or install ramps, widen doors, or make other modifications to live more independently. VA operates three types of grants that accommodate Veterans’ unique circumstances: Specially Adapted Housing, Special Housing Adaptation, and Temporary Residence Adaptation."

Are you getting any benefits at all from the VA now?

Call your city or town building inspector. Very often they have connections to veterans service agencies who might help you.

Contact the VA and ask.
