Why unit classification is the first exhibit
A microcabin village is the format where a single classification decision changes the permit, the property tax, the insurance, the loan term and the programme. The same 400 sq ft unit can be a park model RV built to ANSI A119.5 and titled as a vehicle, a tiny house on a foundation under IRC Appendix Q, a camping unit under a state campground rule, or a dwelling under the residential code. Each answer carries a different wastewater sizing, a different fire-code review, a different assessment and a different place on the lender's collateral schedule. The study settles it before anything else is modelled.
| Classification | Governing standard | Typical size limit | Collateral treatment | Where it is permitted |
|---|---|---|---|---|
| Park model RV | ANSI A119.5; titled and registered as an RV in most states | 400 sq ft in set-up mode | Personal property; equipment-length term | RV parks and campgrounds under the state campground rule |
| Tiny house on a foundation | IRC Appendix Q (AQ in later editions) | 400 sq ft or less excluding lofts | Real property once permanently set and assessed | Residential and lodging districts under the building code |
| Camping unit or camping cabin | State campground rule, for example Wisconsin ATCP 79 or New York Subpart 7-3 | 400 sq ft (Wisconsin, operator-provided units); under 400 sq ft hard-sided (New York camping cabin) | Site improvement at the campground licence | Licensed campgrounds |
| Site-built or prefab cabin over 400 sq ft | Residential or commercial building code | None | Real property | Lodging districts; special use where glamping is not listed |
The state record on park models is uneven: roughly 25 states require A119.5 by statute or rule; Florida allows HUD-code park models up to 500 sq ft; Missouri bars any agency from imposing other building codes on A119.5 units, which makes park model villages comparatively easy to entitle there; Vermont regulates a park model used as a residence at a campground as a building; Washington caps park models at 400 sq ft and requires a state-plan insignia; Oregon requires state plan review and an insignia on top of A119.5; California requires the A119.5 label, bars unlabelled units from RV parks and caps width at 14 feet; Wisconsin pulls a unit into its Uniform Dwelling Code if the chassis and axles are removed. Appendix Q is adopted statewide in California, Georgia, Idaho, Louisiana, Maine, Massachusetts, Montana, New York, Oregon and Virginia, and locally elsewhere; New York's 2020 residential code defines a tiny house as 400 sq ft or less excluding lofts.
Eligibility: the 30-day line
SBA. A village is eligible when more than 50 percent of revenue comes from transients staying 30 days or less and the business complies with zoning (SOP 50 10 8, Section A, Chapter 1, Paragraph E.3, page 20). The same paragraph states that apartment buildings and mobile home parks are not eligible. A village that rents pads to unit owners, or leases units monthly, is a mobile home park or a passive rental for SBA purposes. For 504, project assets must have a useful life of at least 10 years at a fixed location, so only foundation-set units are 504 project assets; park models on their chassis and tiny homes on wheels belong in 7(a) equipment proceeds or equity. Under the September 25, 2026 Technical Policy Updates to SOP 50 10 8.1, a 7(a) loan may run 25 years when at least 51 percent of proceeds fund real estate; otherwise the maturity blends and the equipment portion runs 10 years or less.
USDA. Tourist and recreation facilities, including resort trailer parks and campgrounds operated as a commercial enterprise, are eligible under 7 CFR 5001.105(b)(8); residential trailer parks and other residential housing whose primary purpose is independent housing are ineligible under 5001.118(a). The term is set by the useful economic life of the assets financed and used as collateral, so a park model does not carry a 30-year term.
Tax. Removable units not permanently affixed are generally 5- or 7-year personal property eligible for 100 percent bonus depreciation under Public Law 119-21; foundation-set lodging buildings rented more than 50 percent to transients are 39-year nonresidential real property; site improvements are 15-year. An average stay of seven days or less takes the activity outside the per se rental rule where the owner materially participates. Classification therefore sets both the lender's collateral and the owner's after-tax return.
Unit cost evidence
No public source publishes an installed cost per unit. The study builds it from a documented unit price plus an engineered site takeoff for the parcel.
| Unit | Evidence | Source |
|---|---|---|
| Boxabl Casita (361 sq ft) | $60,000 unit only; $150,000 turnkey, which implies about $90,000 of installation and site scope in the manufacturer's turnkey package | Boxabl, viewed October 2026 |
| ESCAPE Traveler (269 sq ft) | From $95,474 base | ESCAPE, viewed October 2026 |
| ESCAPE Vista | $66,475 | Reseller page, viewed October 2026 |
| Backcountry Hut System 01 (754 sq ft) | $196,276 | Backcountry Hut Company |
| Avrame USA Duo 57 to Duo 120 (A-frame kits, 600 sq ft class) | $22,675 to $34,025, excluding transport, foundation, MEP, finishes and labour | Avrame USA, 2026 |
| Site-built cabin | $110 to $200 per sq ft excluding site work; $275 to $375 custom (Knoxville market, 2026) | Builder and estimator pages |
| Park model RVs | Manufacturer list prices not found in the public record; priced by dealer quote | n/a |
Site components are priced from the serving utility's line-extension tariff ($6.50 to $20.00 per foot beyond free allowances at three cooperatives, with recreational units often excluded from residential allowances), the state DOT's aggregate unit price, and an engineered septic design. Supplier risk is real: Anchored Tiny Homes, a California builder, filed Chapter 7 owing $12.8 million to more than 870 creditors against about $1.25 million of assets. The study conditions the determination on executed supply contracts with deposit protection.
Wastewater and density
Cabins are sized differently from campsites. North Carolina sizes cottages and cabins at 200 gallons per unit per day against 75 to 100 per campsite, so a microcabin village carries roughly 2x to 2.7x the septic design flow of a tent resort of the same unit count. Tennessee sizes alternative systems at 150 gallons per bedroom per day and treats anything over 750 gallons per day as a large system needing site-specific design. Texas sizes hotel-type units at 75 gallons per bed, 60 with water-saving fixtures. Wisconsin caps operator-provided camping units at 400 sq ft and allows at most 20 individual sites per acre; West Virginia allows up to 25 campsites per acre with 1,200 sq ft per site. The study names the system tier and the engineer's cost before the loan is sized, because this is where microcabin budgets fail.
Market evidence
The institutional cabin operators are now hotel-company owned or backed. Marriott acquired Postcard Cabins, 29 properties with more than 1,200 cabins, in December 2024, and folded them into its outdoor collection in October 2025; Huttopia mixes canvas tents with chalets, tiny houses and Frontier Wagons across its six US sites; Clear Sky Resorts operates 45 domes of 438 to 790 sq ft at its Grand Canyon site. Cabin STR markets show the supply picture the study underwrites to: Pigeon Forge at 56 percent occupancy and $344 ADR with listings down 26.9 percent and ADR down 4.8 percent; Broken Bow at 44 percent and $452 with listings up 8 percent; Blue Ridge at 48 percent and $353. AirDNA's 2026 midyear outlook places the strongest supply growth in small-city, rural and mid-size markets.
What the microcabin village study includes
- Unit classification exhibit: the standard each unit meets, the permit it needs, the assessment ratio it attracts and its place on the collateral schedule.
- Eligibility analysis under the SBA transient test, the 504 fixed-location rule and 7 CFR 5001.105 and 5001.118, with the operating model documented as transient lodging.
- Regulatory pathway: zoning, campground licence and density rule, wastewater design flow and system tier, fire code, STR ordinance and the lodging tax stack.
- Development cost from documented unit prices, executed supplier quotes and an engineered site takeoff.
- Market analysis from dated AirDNA and Key Data extracts reconciled across vendors, official visitation counts and a named competitive set with rates sampled on peak, shoulder and off-season nights.
- A ten-year pro forma with DSCR by year and for the weakest three consecutive months at both the 25-year and blended maturity, break-even occupancy and sensitivities.
- A determination: as proposed, or as resized or restructured. See our methodology.

Frequently asked questions
Is a park model RV resort eligible for SBA or USDA financing?
Yes, when it operates as transient lodging with more than 50 percent of revenue from stays of 30 days or less. A resort that rents pads to unit owners or leases monthly is a mobile home park or residential trailer park and is not eligible under either programme.
Can tiny homes be 504 project assets?
Only when permanently set on foundations, with a 10-year useful life at a fixed location. Units on wheels or chassis are equipment and belong in 7(a) proceeds or equity.
What is the size limit for a park model?
400 sq ft in set-up mode under ANSI A119.5. Florida allows HUD-code park models to 500 sq ft; Washington caps park models at 400 sq ft and requires a state insignia.
How much does a microcabin cost installed?
Documented unit prices run from about $60,000 to $196,000 for 269 to 754 sq ft; no public source publishes an installed figure, so the study adds an engineered site takeoff and executed supplier quotes.
How does wastewater sizing differ from a tent resort?
Cabins are sized at 200 gallons per unit per day in North Carolina and 150 per bedroom in Tennessee, against 75 to 100 per campsite, so a cabin village carries roughly double the septic design flow of a tent resort of the same count.
Are microcabins special purpose for 504?
That is the CDC's determination. An operator-run village on one parcel with shared septic and amenities is most likely classified as lodging, which means 15 percent equity, or 20 percent for a new business.
