Can You Use RVs and Mobile Homes for H-2A Worker Housing?
A fencing contractor in Wyoming lands contracts across Montana, Idaho, and Utah. Hotels every night drain the budget and exhaust the crew. Fifth-wheel trailers seem like the obvious solution—workers have their own space, costs drop dramatically, and the mobile housing follows the work. But will the Department of Labor allow it for H-2A workers?
A rancher expanding into H-2A for the first time faces a similar question from a different angle. Building a traditional bunkhouse means foundation work, septic systems, water lines, electrical service, and potentially a year of permitting and construction. A few quality mobile homes could be on-site and ready for inspection in weeks. Is that legal?
The answer to both questions is yes—mobile housing units including RVs, campers, fifth-wheels, and mobile homes are permitted for H-2A workers. But they must meet every applicable standard without exception, pass mandatory State Workforce Agency inspection, and comply with all the same requirements as fixed-site housing.
What Federal Regulations Say About Mobile Housing
The H-2A housing regulations at 20 CFR § 655.122(d) require employers to provide housing at no cost to workers who cannot reasonably return to their residence within the same day. The regulation specifies two compliance paths for employer-provided housing:
Option 1: Full compliance with OSHA standards at 29 CFR § 1910.142 (Temporary Labor Camps)
Option 2: Full compliance with DOL standards at 20 CFR §§ 654.404-654.417.
Neither regulation creates a separate category for mobile housing or grants mobile units any special exemptions. The regulations apply to all employer-provided housing regardless of whether the structure is fixed or mobile.
The Special-Procedures Regime: 20 CFR 655.304
The general mobile housing analysis above applies to fixed-site employers who want to use mobile units at their own operations. A parallel regulatory regime, codified at 20 CFR 655.300 through 655.304, governs three occupations where the work itself is itinerant: custom combining, animal shearing, and commercial beekeeping. Under 20 CFR 655.304, employers in these occupations may use a camper, trailer, or other mobile housing unit as worker housing, subject to detailed standards on drinking water, waste disposal, structural soundness, heating, electricity, and fire safety. The special-procedures regime also permits a single labor certification and job order to cover a multi-state itinerary, rather than separate filings for each state.
Paragraph 655.304(a)(2) contains one of the more distinctive provisions in US labor regulation: “A Canadian employer performing custom combining operations in the United States whose mobile housing unit is located in Canada when not in use must have the housing unit inspected and approved by an authorized representative of the Federal or provincial government of Canada, in accordance with inspection procedures and applicable standards for such housing under Canadian law or regulation.” In effect, the regulation accepts a Canadian Federal or provincial inspection as a substitute for the US inspection that would otherwise apply.
If your operation is a multi-state custom combining crew rather than a fixed-site farm using a trailer for a few seasonal workers, the special-procedures framework is likely the one you should be planning against. For a full treatment, see our article on Canadian Custom Combine Crews and the H-2A Program.
The Controlling OSHA Interpretation
In June 1991, OSHA addressed mobile housing directly in an interpretation letter that remains controlling authority today. An employer had asked whether the 100-square-foot-per-person requirement applied to mobile housing units. OSHA’s response was unequivocal:
“All mobile housing units, without exception, must comply with the general provisions of .142, including the 100 square feet provisions of standard. The mobility of the units does not relieve the employer from complying with the relevant provisions of the standard.”
This interpretation establishes a critical principle: mobility is not a basis for reduced requirements or special treatment. A fifth-wheel trailer used for H-2A housing must meet exactly the same standards as a stick-built bunkhouse.
OSHA Standards That Apply to Mobile Units
The OSHA Temporary Labor Camp standard at 29 CFR § 1910.142 applies comprehensively to mobile housing. Key requirements include:
Site and Drainage: Housing sites must be adequately drained and not subject to periodic flooding. Sites cannot be located within 200 feet of swamps, pools, or other standing water unless those water surfaces can be subjected to mosquito control measures. The site must be located so drainage from and through the camp will not endanger any domestic or public water supply.
Space Requirements: Each room used only for sleeping must provide at least 50 square feet of floor space per occupant. If workers cook, live, and sleep in the same room, each occupant must have at least 100 square feet of floor space. Beds must be spaced at least three feet apart in all directions and at least 12 inches off the floor. Only double-deck bunks are permitted (no triple bunks), with at least 27 inches of space between the lower and upper bunk.
Heating: If the housing will be occupied between October 1 and April 1 (the heating season in most Rocky Mountain West locations), a heating system must be installed. Portable unvented kerosene or propane heaters are not permitted. Open-grate fires are not acceptable. Wood stoves are discouraged but may be used if properly inspected and approved. All heating systems must be installed and inspected by code enforcement authorities before the State Workforce Agency inspection. If non-vented gas heaters are used, working carbon monoxide detectors must be present.
Water Supply: An adequate and convenient water supply approved by the state or local health authority must be provided. The system must have adequate pressure and a supply sufficient to meet the needs of all occupants.
Toilet Facilities: Where toilet facilities are shared, water closets or privy seats must be provided for each sex based on the maximum number of persons of that sex the camp will house at any one time, in a ratio of one unit per 15 persons, with a minimum of two units for any shared facility.
Bathing and Laundry: Shower facilities must provide at least one shower head for each 10 persons. Facilities for washing clothes must include water, basins or tubs, and a supply of soap. Laundry facilities must be maintained in a sanitary condition.
Lighting and Electrical: Every habitable room must have at least one ceiling-type light fixture and one wall-type electrical outlet. In common rooms such as kitchens and living areas, the minimum illuminance level must be 30 foot-candles measured 30 inches above the floor.
Garbage Disposal: At least two covered garbage containers with garbage bags must be provided. Garbage must be removed at least twice weekly. If workers remove light bulbs from fixtures (a surprisingly common issue), the employer remains responsible for the violation.
Fire Safety: Smoke detectors are required in each bedroom. Two-story structures must have a ladder from the second floor for emergency egress.
Vermin Control: The employer must provide sealed food storage containers and supplies to help workers combat insects, rodents, and vermin—a particular concern in agricultural settings.
These requirements apply identically whether the housing is a mobile home, an RV, a converted barn, or a purpose-built bunkhouse.
State Workforce Agency Inspection Requirements
Federal regulations at 20 CFR § 655.122(d)(6)(ii) require the State Workforce Agency to inspect and certify all employer-provided housing, including mobile units. The SWA must verify that:
- The housing is sufficient to accommodate the number of workers requested
- All housing meets the applicable standards under § 655.122(d)(1)(i)
- The inspection occurs no later than 30 calendar days before the first date of need stated in the application
This 30-day deadline is absolute. If you plan to file for an April 15 start date, the housing inspection must be completed by March 16. The inspection requirement applies to each housing unit. If you’re using five mobile homes, the SWA inspects all five. If you’re using three RVs and two apartments, all five get inspected.
For farm labor contractors specifically, housing requirements carry extra weight. Under 20 CFR § 655.132(e)(1), when a fixed-site agricultural business provides housing for workers employed through a farm labor contractor, the housing must still comply with § 655.122(d) and receive SWA certification. The involvement of an FLC does not change housing standards or bypass inspection requirements.
State-Specific Restrictions on Mobile Housing
While federal regulations permit mobile housing, some states impose additional restrictions. In my H-2A practice across the Rocky Mountain West, I’ve observed that state enforcement approaches vary significantly.
Mobile housing comes up most often for contractors moving crews between several growers’ places. If that describes your operation, read our guide on what DOL requires from a labor contractor before you plan the housing, because the worksite list drives everything else.
Before committing to mobile housing, verify with your State Workforce Agency whether campers or mobile homes are accepted in your state. Some states that serve agricultural employers in our region have been known to prohibit or restrict the use of certain types of mobile housing for H-2A workers. A call to your SWA before purchasing or leasing RVs can prevent expensive mistakes.
Even in states that accept mobile housing, local regulations may apply. County health departments sometimes impose requirements beyond federal standards for temporary agricultural housing. City or county zoning ordinances may restrict where mobile housing can be sited. These local requirements layer on top of federal standards—they don’t replace them.
When Mobile Housing Makes Economic Sense
For many agricultural employers and farm labor contractors, mobile housing solves real problems. Understanding when it makes sense requires comparing it to the alternatives.
The Hotel Model
A fencing contractor working across Wyoming, Montana, and Idaho might pay $120 per night per worker for basic hotel rooms. With a six-person crew working 180 days, that’s $129,600 in lodging costs for the season. Workers spend evenings in rotating hotel rooms, never establishing a stable base. Meal costs rise because workers eat out rather than cooking. Worker fatigue increases from constant relocation.
The Fixed Bunkhouse Model
A rancher adding H-2A workers for the first time might consider building permanent housing. A basic four-bedroom bunkhouse with shared kitchen and bathrooms costs $150,000-$250,000 to construct in Montana or Wyoming as of 2026, depending on site conditions and utility access. If you need septic, well, and electrical service run to a remote site, add another $50,000-$100,000. Construction timelines run 8-12 months from permitting through completion. For an employer with seasonal needs who might use different H-2A workers each year, that’s significant capital tied up in an asset used 6-8 months annually.
The Mobile Housing Model
Quality used mobile homes suitable for H-2A housing run $15,000-$40,000 each depending on size and condition. A fifth-wheel RV suitable for two workers costs $20,000-$45,000 new or $8,000-$18,000 used. Setup costs include utility hookups (water, septic, electric), but these are far less extensive than permanent construction—typically $5,000-$15,000 per site depending on existing infrastructure.
For the fencing contractor scenario, purchasing three fifth-wheel trailers at $30,000 each ($90,000 total) plus $30,000 in hookups at a home base creates a $120,000 one-time investment that eliminates $129,600 in annual hotel costs. The trailers can travel to job sites where hookups are available, or workers can stay at the home base with daily transportation to distant work sites.
For the rancher scenario, purchasing two mobile homes at $30,000 each plus $25,000 in site preparation totals $85,000—roughly half the cost of permanent construction, with the work completed in weeks rather than months.
The mobile housing approach works particularly well when:
- Work locations change seasonally or annually
- The employer is testing the H-2A program before committing to permanent infrastructure
- Workers will be divided among multiple work sites across a region
- The employer wants flexibility to adjust housing capacity year to year
- Existing infrastructure (power, water, septic) makes setup relatively simple
Mobile housing makes less sense when:
- The employer has a stable, long-term location with ample space for permanent construction
- Local regulations prohibit or severely restrict mobile housing placement
- Site conditions make utility hookups extremely expensive
- The employer plans to use the same housing for 10+ years (permanent construction may be more economical long-term)
Common Inspection Failures with Mobile Units
State Workforce Agency inspections of mobile housing commonly identify the same issues. Understanding these patterns helps employers prepare housing that passes on the first attempt.
Inadequate Square Footage
Many RVs and mobile homes marketed as sleeping six or eight people fail to provide the required 50 square feet per person in sleeping areas. A “sleeps 8” RV might have 300 square feet of sleeping space, which only meets the standard for six occupants. Always measure the actual floor space in rooms where workers will sleep, excluding bathrooms, hallways, and storage areas. Don’t rely on the manufacturer’s occupancy rating.
Insufficient Bathroom Facilities
A mobile home with one bathroom fails the standard if you’re housing more than 15 workers. The 1:15 ratio applies to shared facilities. If you’re using three mobile homes with one bathroom each to house 18 workers, you need at least two bathrooms available (18 ÷ 15 = 1.2, rounded up to 2). This often requires designating specific units for specific purposes or installing additional facilities.
Improper Heating Systems
Many RVs come equipped with propane heating systems that do not meet OSHA standards. Unvented portable heaters are specifically prohibited. If the mobile unit’s heating system relies on unvented propane, you must either install an approved heating system or provide access to a separate heated facility that meets standards.
Missing Safety Equipment
Smoke detectors, fire extinguishers, carbon monoxide detectors (if using gas appliances), and proper emergency egress are frequently missing or inadequate in mobile housing. These items must be present and functional at the time of inspection.
Inadequate Drainage and Site Preparation
A mobile home parked on ungraded ground may be compliant internally but fail site requirements. The area around the unit must drain properly, the site cannot be within 200 feet of standing water without mosquito control, and the site must not pose a flood risk. Proper grading and drainage work before the inspection often determines pass or fail.
Water Supply Issues
In remote or rural locations, water supply often causes problems. If the mobile housing connects to a well, the well must be tested and approved by the state or local health authority. If workers will haul water, you must provide adequate storage and maintain sanitary conditions. “Adequate supply” means enough water for drinking, cooking, bathing, and laundry for all occupants.
Housing That Becomes Unavailable
Even after housing passes inspection, problems can arise. The regulations at 20 CFR § 655.122(d)(6)(iv) address what happens when certified housing becomes unavailable for reasons outside the employer’s control.
If mobile housing is damaged, destroyed, or otherwise becomes uninhabitable after inspection but before workers arrive, you may substitute other housing that meets the same standards. You must promptly notify the SWA in writing, explain the reason for the change, and provide evidence that the substitute housing complies with applicable standards.
For mobile housing, this provision has practical applications. If a fifth-wheel trailer is damaged in transport to a work site, you can substitute another comparable unit. But you must document the circumstances that made the original housing unavailable and demonstrate that the substitution was genuinely outside your control. “We decided to use a different RV” doesn’t qualify. “The original RV was totaled in a highway accident” does.
The SWA will inspect the substitute housing if time permits before workers arrive. If the SWA determines the substitute housing doesn’t meet standards, you must cure the deficiencies immediately. Failure to provide compliant housing can result in denial of a pending application or revocation of an approved certification.
Farm Labor Contractor Considerations
Farm labor contractors face the same housing requirements as direct agricultural employers, but with additional complexity. If you’re operating as an FLC and providing housing, remember several points:
You Bear the Compliance Burden
Even if a fixed-site agricultural business agrees to provide housing for workers you supply, 20 CFR § 655.132(e)(1) requires proof that all housing complies with § 655.122(d) and has been certified by the SWA. The FLC application cannot proceed without this certification. If the fixed-site business’s housing fails inspection, your application stalls until housing is brought into compliance or alternative housing is secured.
Mobile Housing Offers Flexibility
For FLCs who supply labor to multiple farms or ranches, mobile housing provides operational flexibility that fixed housing cannot match. A fencing contractor operating as an FLC can move housing units with the crew as work locations change, rather than relying on each farm to provide compliant housing. This gives the FLC control over a critical program requirement.
Vehicle and Housing Standards Both Apply
FLCs using mobile housing that also serves as transportation must ensure compliance with both housing standards (29 CFR § 1910.142) and transportation standards (29 CFR § 500.104-500.128). A fifth-wheel trailer used as housing and towed by the crew to different work sites must meet both sets of requirements. The housing inspection and vehicle inspection are separate processes.
Bond Calculations Don’t Change
The surety bond required for FLCs under 20 CFR § 655.132(c) is calculated based on the number of workers requested, not the type of housing provided. Using mobile housing instead of fixed housing doesn’t reduce the bond amount or change the calculation methodology.
Strategic Guidance on Mobile Housing
Based on the firm’s H-2A practice across Montana, North Dakota, Wyoming, Utah, Idaho, and Colorado, several strategic considerations emerge for employers considering mobile housing:
Start the Process Early
Housing inspection is often the bottleneck in H-2A applications. SWAs in rural states may have limited inspection staff covering enormous geographic areas. Requesting an inspection in February for an April start date gives you time to address any deficiencies and request a re-inspection if needed. Waiting until March to request inspection for an April start creates unnecessary risk.
Measure Before You Buy
Many employers purchase mobile units based on advertised sleeping capacity only to discover during inspection that the units don’t meet square footage requirements. Before purchasing or leasing, physically measure the floor space in sleeping areas. If purchasing used units, have them inspected by a local building inspector or RV technician to identify any issues before the SWA inspection.
Document Your Setup
Take photographs of the housing setup showing site drainage, utility connections, spacing between units, fire safety equipment, and interior layout. If questions arise during or after inspection, documentation helps demonstrate compliance. For FLCs working across multiple states, documentation also helps when working with different SWAs who may have different inspection protocols.
Maintain a Relationship with Your SWA
SWA inspectors in Montana, Wyoming, and North Dakota often work with the same agricultural employers year after year. If you used mobile housing last season and it passed inspection, maintain that relationship. Inform the SWA early if you’re using the same units in the same configuration. Some SWAs may streamline re-inspection if the housing and setup haven’t changed materially.
Consider the Full Lifecycle Cost
Mobile housing has lower upfront costs than permanent construction but higher ongoing maintenance requirements. RVs and mobile homes deteriorate faster than stick-built structures when used seasonally. Budget for annual maintenance, repairs, and eventual replacement. A $25,000 mobile home might need $2,000-$3,000 in annual upkeep and require replacement after 8-10 years of seasonal use.
Plan for Expansion or Contraction
One advantage of mobile housing is scalability. If your H-2A needs increase, you can add units without major construction. If needs decrease, you can sell units or redeploy them. This flexibility is particularly valuable for employers still establishing their optimal crew size or FLCs whose contracts vary year to year.
Bottom Line for Agricultural Employers
Mobile housing—RVs, fifth-wheels, campers, and mobile homes—is legally permissible and often economically advantageous for H-2A employers and farm labor contractors. The mobility of the housing creates no legal barrier and triggers no special regulatory category. These units must simply meet the same comprehensive OSHA and DOL standards that apply to all employer-provided housing.
The fencing contractor question posed at the beginning of this article has a clear answer: Yes, you can use fifth-wheel trailers for your H-2A crew as they work across Wyoming, Montana, and Idaho. You’ll save substantially compared to hotels, give your workers stable housing, and maintain flexibility as work locations change. But those trailers must meet every OSHA requirement, pass SWA inspection at least 30 days before your workers arrive, and comply with any state-specific restrictions in the states where you operate.
The rancher question has an equally clear answer: Yes, you can use mobile homes instead of building a permanent bunkhouse, get housing ready faster, and reduce your capital investment significantly. But those mobile homes must still meet all applicable housing standards, and the timeline advantage only materializes if you start the inspection process early enough to address any deficiencies identified during inspection.
The regulations don’t prohibit mobile housing. They require compliant housing, and compliance is achievable with proper planning, accurate measurement, and attention to OSHA’s detailed requirements. For many employers across the Rocky Mountain West, mobile housing represents the most practical solution to the H-2A housing requirement.
