Prefab Homes in Colorado 2026: Snow Load, STR Rules, Makers
If you want a prefab home on a Colorado mountain lot, start with your parcel’s ground snow load from the county. In Larimer County, that figure rises from 55 pounds per square foot (psf) at 5,000 feet to 160 psf at 9,000 feet. Backcountry Hut is the only maker here that publishes a snow-load rating: 50 psf for its standard System 01 and up to 430 psf for its heavy-snow System 02. Studio Home builds in Colorado, and its Summit 308 starts at $92,173 plus installation.
The table lists 4 makers that publish a price and a delivery area that includes Colorado. Where a maker does not publish a figure, the cell says “Not published.”
The Colorado Table
Backcountry Hut sells in Canadian dollars, and its US figures are its own conversions that “may vary due to exchange rate fluctuations.” Its prices do not include permits and taxes. DC Structures’ Colorado page lists the McKenzie at 651 sq ft and the Modern McKenzie at 721 sq ft, while the model’s own page says 720 sq ft, so confirm the size in the quote.
Snow Load Is Set by Your County
Colorado counties and cities publish their own snow-load figures. Here are 3 examples, each from the local government’s own page.
- Larimer County. Its structural design information sets ground snow load by elevation: 55 psf up to 5,000 feet, 70 psf up to 6,000 feet, 80 psf up to 6,500 feet, 95 psf up to 7,000 feet, 110 psf up to 8,000 feet, and 160 psf up to 9,000 feet. At or above 10,000 feet, the figure comes from the Structural Engineers Association of Colorado (SEAC) snow-load report. Homes may follow the International Residential Code’s prescriptive rules only where ground snow load does not exceed 70 psf.
- Gunnison County. Its climate design criteria list ground snow load as “Varies.” New construction must meet the snow load at the building site, taken from the 2016 SEAC report.
- Cañon City. Its building department’s design criteria set the snow load, ground and roof, at 30 psf.
A Larimer County lot at 7,000 feet carries a ground snow load more than 3 times Cañon City’s figure. Ask the building department for your parcel’s figure, and ask whether it requires an engineered design.
What Each Maker Publishes on Snow Load
Backcountry Hut publishes a maximum for each system on its FAQ page. It says heavy-snow systems cost “approximately 10-15% more than a standard System.” As an example only, 10% to 15% on the $196,276 Great Lakes layout is $19,628 to $29,441.
The other 3 makers do not publish a figure in psf. The county figures above are ground snow loads, and the roof figure is calculated from them, so ask each maker whether its rating is a roof or a ground figure. Then ask for stamped engineering at your parcel’s load before you pay a deposit.

How Colorado Regulates Factory-Built Homes
Colorado’s state housing board sets standards for manufactured homes and factory-built structures. House Bill 22-1242, signed on May 17, 2022, and effective August 10, 2022, added tiny homes to that regulation “on substantially similar terms.” It also gave the board the duty to regulate foundations for all 3 where no construction standards exist. Ask the maker how its unit is certified for installation in Colorado, and ask the county building department what it inspects on-site.
Short-Term Rental Rules in 2 Colorado Places
Each Colorado town or county sets its own rental rules. These 2 examples come from each place’s own page.
- Town of Frisco, Summit County. Short-term rental licenses are capped at 25% of the town’s 3,600 residential housing units, “allowing a maximum of 900 STR licenses,” under Ordinance 22-10, effective October 17, 2022. The town reached the cap in February 2023 and has used a waitlist since.
- City and County of Denver. A stay of fewer than 29 nights needs a short-term rental license, and “the property being rented must be your primary residence.”
For other addresses, use the zoning rules guide before you buy land.
Where to Start
Get your parcel’s ground snow load first. In Larimer County, a home on a site above 70 psf cannot use the residential code’s prescriptive rules.
Ask for a snow-load rating in psf. Only Backcountry Hut publishes one. A mountain lot may need its heavy-snow version, at about 10% to 15% more.
Check the town’s license count before you buy land. Frisco reached its 900-license cap in February 2023, so a new owner there joins a waitlist.
Plan Denver rentals around your primary residence. Denver licenses short-term rentals only at the host’s primary residence, so a second home there cannot hold a license.
Before You Order
Run these 3 checks before a deposit, in order.
- Price the site work. Run the lot through the site-prep cost estimator. Larimer County sets frost depth at 30 inches and Gunnison County at 36 inches, and no price in the table includes a foundation.
- Confirm the loan. Start with the lender locator. Ask whether the lender finances a kit or a shell.
- Confirm the county and the town. Ask the building department for your parcel’s ground snow load, and ask the clerk whether a short-term rental license is available at that address.
