Virginia homeowners and prospective buyers in dozens of localities face a direct change in what can be built on residential lots after Governor Abigail Spanberger signed HB655 and SB346 into law earlier this year. The bills rewrite the state’s zoning rules for manufactured homes, requiring every locality to allow qualifying factory-built houses on any lot where a traditional site-built home is permitted. The move targets a persistent bottleneck in housing supply: local ordinances that have long kept manufactured homes out of single-family neighborhoods, even as production of those homes has continued at a steady pace nationwide.
How Virginia’s zoning rewrite changes the rules for factory-built homes
The new law updates state zoning provisions governing manufactured housing, which now establish uniform statewide regulations for placement. Under the revised statute, localities must permit qualifying manufactured homes in any zoning district where site-built single-family housing is allowed, provided the home is converted to real property and placed on an individual lot. The homes must also meet federal construction and safety standards set under 42 U.S.C. Section 5403, commonly known as the HUD Code, which establishes a national floor for structural integrity, fire resistance, and energy efficiency in factory-built housing.
That distinction matters because it draws a clear line between federal authority over how manufactured homes are built and state authority over where they can be placed. Until this year, Virginia localities could effectively ban manufactured homes from residential zones through restrictive local ordinances, often by limiting them to specific manufactured-home parks or rural districts. The updated statute removes that local veto for homes meeting the specified conditions, while still allowing local governments to enforce generally applicable design, setback, and infrastructure rules that also apply to site-built houses.
Governor Spanberger has framed the legislation as part of a broader housing initiative aimed at expanding residential supply and making ownership more attainable for moderate-income households. By opening up more lots to factory-built units, the administration is betting that lower construction costs and shorter build times can translate into additional starter homes without requiring major public subsidies.
Where manufactured-home permits could rise fastest
The strongest near-term effects will likely show up in localities that previously maintained outright bans or heavy restrictions on manufactured housing in single-family zones. Those communities face the starkest gap between old rules and new requirements. A reasonable expectation is that localities with the strictest prior zoning bans will see the largest relative increase in approved manufactured-home permits over the next 18 months, even if overall statewide housing starts remain flat. Where the barrier was highest, removing it creates the most room for new activity.
Suburban jurisdictions on the edges of the state’s largest metro areas may be especially sensitive to the change. Many of those communities have experienced rapid price appreciation but limited greenfield land, making infill construction on scattered lots more attractive. If manufactured homes can be sited on those lots under the same basic zoning as conventional houses, builders may test whether buyers are willing to trade some customization for lower prices and faster delivery.
No public dataset yet tracks exactly how many Virginia localities maintained such bans before the law changed, or how many parcels will newly qualify. The U.S. Census Bureau’s manufactured housing series provides monthly shipment counts for new units by state and size, but those figures measure factory output, not local placement or permitting. A spike in Virginia-bound shipments would signal rising demand, yet it would still not show where within the Commonwealth those homes ultimately land.
Tracking the law’s real-world impact will therefore require locality-level permit data, ideally broken out by structure type. Some of that information exists in scattered building department reports and state construction code filings, but it has not been compiled into a centralized, public dashboard. Housing researchers and advocates are likely to watch for patterns in building permits, property assessments, and subdivision approvals to gauge whether manufactured homes are actually gaining a foothold in neighborhoods that previously excluded them.
Financing, neighborhood design, and remaining questions
Access to mortgage credit will be a major factor in determining how quickly the new zoning translates into completed homes. Many manufactured units are still financed as personal property, but the Virginia statute conditions by-right placement on converting the home to real estate and placing it on an individual lot. That structure aligns more closely with conventional mortgages and with federal housing-finance programs that favor real-property loans over chattel lending.
Local design standards could also shape how visible the shift becomes. Some localities may respond by updating aesthetic rules-such as roof pitch, siding materials, or foundation treatments-to ensure that manufactured homes resemble nearby site-built houses from the street. Others may simply apply existing single-family standards, allowing a wider range of appearances so long as basic safety and setback requirements are met.
The legislation leaves unanswered how quickly local zoning codes will be brought into formal compliance. While the state law is already in force, many local ordinances still contain language that conflicts with the new mandate. Until those codes are updated, homeowners and builders may need to rely on state preemption language when seeking permits, a process that could generate test cases and, potentially, litigation if localities resist.
For now, Virginia’s experiment will offer an early look at whether removing zoning barriers for HUD Code homes can meaningfully expand the supply of lower-cost ownership options in built-out communities. If manufactured-home placements rise without triggering sharp neighborhood opposition, the model could influence future housing debates in other states facing similar affordability pressures.
