Vermont bills aim to expand manufactured housing affordability

Vermont’s legislature took two steps Wednesday to make factory-built homes easier to buy and keep affordable, advancing bills that now head to a Senate floor vote and the governor’s desk.

Two Senate committees approved H.757, which passed the House in March. The bill expands protections for manufactured homeowners and locks in long-term affordability for housing cooperatives. It awaits a full Senate vote.

The House passed a rural housing finance and production bill that creates new tools for factory-built home construction across Vermont. It is a scaled-back version of a more aggressive approach and now heads to the governor.

Vermont’s progress comes as manufactured housing secures widening recognition as one of the most viable, practical measures to address supply constraints at the root of the housing affordability crisis. At least 10 states have enacted legislation that protects manufactured homes from discriminatory local zoning.

Congress folded significant manufactured housing reforms into the 21st Century ROAD to Housing Act, sweeping bipartisan legislation the House approved Wednesday. Section 301 would scrap the requirement that manufactured homes be built on a permanent chassis. Advocates say the change would unlock new design possibilities and reduce production costs at scale.

What’s in it for builders

Researchers and industry analysts have long documented manufactured housing’s cost advantage over site-built construction. For an equally long stretch, policy barriers have suppressed the sector’s potential.

A November 2025 study by Harvard University’s Joint Center for Housing Studies found that off-site construction methods offer affordable housing developers a faster, less costly path than conventional site-built construction. The study validated what manufactured housing producers have argued for years.

“We just don’t see starter homes anymore,” Jason Webster, president of Huntington Homes, a Vermont modular manufacturer, said in testimony at a late April committee hearing on the rural financing bill. “I honestly can’t tell you in the last 25 years the last starter home we built.”

Vermont’s sales tax exemption expansion does not guarantee a surge in buyers. It signals, however, that the state treats manufactured housing as a legitimate, permanent part of its housing stock. That posture reduces regulatory risk for manufacturers, dealers and community developers deciding where to invest.

When states layer favorable tax treatment onto anti-exclusion zoning protections, they create a stable, predictable environment that can support site selections, inventory investment and financing product development – the upstream decisions that determine whether manufactured housing scales as an affordability tool.

Vermont’s zoning foundation

Vermont’s commitment to manufactured housing predates the current wave of state-level reform by more than two decades. The state’s anti-exclusion statute has barred municipal zoning bylaws from excluding manufactured homes since 2004. Towns must treat factory-built housing the same as site-built single-family homes.

The law gave homeowners and developers a statutory shield against exclusionary local bylaws. Enforcement, however, remained uneven across Vermont’s 246 municipalities.

In 2023, lawmakers strengthened the broader zoning framework with the HOME Act. The law required towns to allow duplexes anywhere single-family homes are permitted, capped parking requirements and mandated minimum densities in areas served by water and sewer. Those provisions opened more land to higher-density and alternative housing types statewide.

Vermont has stopped short of the more aggressive standard that other states have enacted. At least five states – Kentucky, Maine, Maryland, Montana and Virginia – have passed equal-treatment laws since 2024 requiring localities to permit manufactured housing wherever single-family homes are allowed. Maine and Maryland went further, legalizing manufactured housing by right in any zone permitting single-family dwellings.

Lawmakers in neighboring New Hampshire tried to follow suit last year. Procedural maneuvering killed the bill despite its passing in both chambers. Vermont relies instead on its 2004 anti-exclusion statute – a meaningful protection that stops short of affirmatively guaranteeing placement.

Vermont’s latest bills build on that foundation.

A bill scaled back but still standing

H.775 began as an ambitious attempt to use the state’s financial infrastructure to accelerate factory-built housing production in rural Vermont. As introduced in January, it would have created an off-site construction accelerator pilot program.

The program would have been backed by roughly $12 million in State Treasurer credit facilities. That would have given builders a reliable financing pipeline for small rural projects that the private market has long ignored. It didn’t survive.

S.328, introduced in the Senate, addressed the rental side of the affordability equation. The bill tied rent stabilization to the Consumer Price Index to prevent lower-income residents from being priced out of housing they might eventually buy.

The two bills were merged in the Senate Economic Development Committee into a single housing production vehicle. The bill’s most ambitious provision did not survive. Department of Housing and Community Development officials told lawmakers the agency lacked the capacity to administer the accelerator. Gov. Phil Scott requested its removal, and the committee agreed.

“While this may be pragmatic, it is still disappointing to see a pilot that promises to transform our housing development pipeline and reduce per-unit costs be put back on the shelf,” the Campaign for Vermont noted in a legislative update.

Inside H.757

The legislation targets two distinct mechanisms. It would require limited-equity cooperative housing corporations to hold a first right of repurchase of a departing member’s interest, keeping units permanently affordable and out of market-rate resale. That preserves a cooperative’s affordability mission across generations, preventing the market drift that has eroded affordable housing stock in higher-cost states.

The bill also increases the percentage of sales receipts exempt from Vermont’s sales and use tax for mobile and modular homes. Supporters say the change aligns tax treatment with site-built homes and reduces a price gap that puts factory-built housing out of reach for some lower-income buyers.

H.757’s movement through two Senate committees on Wednesday signals broad bipartisan support. But the bill faces a procedural hurdle: the Senate Economic Development Committee attached a proposed amendment.

If the full Senate adopts changes, the House must concur or the chambers will negotiate a final version in conference committee. The session ends May 29.
