WASHINGTON — Landlords and local officials across the country say a White House proposal to eject undocumented immigrants from subsidized housing would displace some of their most reliable tenants and add major financial strains to an already cash-strapped system.

Officials with the Department of Housing and Urban Development, prodded by hard-liners like Stephen Miller, President Trump’s top immigration adviser, say the proposal, which would prohibit households with at least one unauthorized immigrant from living in federally subsidized housing, is needed to ensure that only verified citizens receive the benefits.

But landlords and local public housing administrators who would have to evict as many as 108,000 people receiving benefits say the plan would, in essence, add immigration enforcement to their responsibility of providing shelter to some of the nation’s most vulnerable families. Undocumented immigrants, they say, generally pay the rent on time, in part out of fear of attracting attention and referrals to law enforcement.

“The housing authority would bear the brunt of the expense of having to completely evict and go through the court action of having to evict these families,” said Sylvia Blanco, the chief operating officer at the Housing Authority of the City of Austin, Tex. “We would be on the hook for having to pay for that.”
