Innovative and Unique Homes#

We welcome a variety of home types in Fort Collins, however some types of homes are not addressed in Building Code. Below is a list of innovative home types and considerations.

Tiny Houses:

Must be site built on a permanent foundation
We have adopted the Tiny House appendix Q/AQ for homes 400 sf or less under the International Residential Code!
Tiny homes on wheels are considered vehicles/campers and subject to local camping ordinance.

Shipping Containers:

Plans must be fully engineered by a Colorado Licensed Structural Engineer (including all openings/penetrations in the shipping container, foundation, must comply with local wind a snow loads).
Must comply with IRC energy code requirements (Residential Energy Compliance Form)
An air tightness test is required.
Must comply with all adopted codes requirements (electric, plumbing, mechanical, etc.)

Earth Ships / Straw Bale:

Must comply with IRC energy code requirements (Residential Energy Compliance Form)
An air tightness test is required.

Permanently built yurt shaped structures will need to be fully engineered by a Colorado Licensed Structural Engineer.

Accessory Dwelling Unit / Mother-in-law suite / Carriage House:

A complete and independent residential unit including all of the following may be considered a duplex or second dwelling unit:

Kitchen (with cooking appliance)
Bathroom
Sleeping space/living space

Contact Zoning to see if a second dwelling unit is permitted in your zone district based on the property address. Adding an additional dwelling unit on lot can have significant permit fees and building code upgrades associated as well, (like that of a new house).

Residential Stock Plans

Residential Stock Plans for New Homes#

Please contact us if you plan to submit a stock plan: revcoord@fcgov.com

When the same home design will be built at least three times with limited variations, a stock plan design or master plan can be submitted for a single review and then built multiple times and connected to a site specific permit.

For example: Imagine a grab-and-go style restaurant (where you place an order, take a number and find a table). The stock plan is like the menu, and the site specific permit is like you order and table number.
