Patio Covers, Pergolas & Decks in Ken Caryl, CO

Building a Patio Cover, Pergola or Deck in Ken Caryl: What to Know

Ken Caryl is unincorporated Jefferson County, so permits come from Jefferson County Building Safety (303-271-8260) through the Jeffco Citizen Portal. The county adopted the 2024 International Codes effective July 1, 2026. At 6,500 feet and below, the county's table uses a 43 psf ground snow load and a 30 psf roof snow load, with a 36-inch frost depth.

Start with the Ken-Caryl Ranch Architectural Committee. The Ken-Caryl Ranch Master Association's Architectural Committee must approve all exterior improvements before work starts. You apply through the association's online portal, most decisions come back within 2 weeks (up to 30 days), neighbors must be notified, and additions have a $250 minimum fee. Some homes also have a sub-association that needs to sign off. We provide drawings and material specs for your application.

When you need a permit:

• Decks: under the county's deck guide, decks 12 inches or lower don't need a permit, decks over 12 inches and under 30 inches need a Miscellaneous Permit, and decks 30 inches or higher need a Building Permit. A cover over a deck needs a Building Permit at any height.
• Freestanding structures: detached accessory structures of 120 sq ft or less, at least 10 feet from the house and no taller than 14 feet, can be exempt from a building permit. Anything closer to the house needs a Building Permit.
• Patio covers, screen rooms and sunrooms: the county publishes separate "Patio Cover" and "Enclosing Patio" building guides. Expect a permit.

General contractors need a Jefferson County Contractors License. Confirm current requirements with Building Safety before you build.
