The county's year-round town
Silverthorne is where Summit County lives when the lifts close: 4,700 residents at 9,035 feet along the Blue River, with the Gore Range filling the western sky. Wildernest and Mesa Cortina carry 1970s-to-90s condos and townhomes on steep west-facing slopes; Three Peaks, Eagles Nest, and Angler Mountain Ranch hold custom homes on golf-course lots; Smith Ranch is the new workforce neighborhood; and the downtown corridor runs along the river. Almost every one of those homes has, or wants, a deck pointed at the Gore Range.
Permits through the town, reviewed by CBCS
Silverthorne Community Development's Building division issues deck permits inside town limits, and since August 2026 plan review and inspections are contracted to Comprehensive Building Code Services, CBCS. Applications go through the town's SmartGov portal, decks and deck replacements both need a permit, and every permit carries a construction-management and stormwater plan. Contractors need a town business license, which we hold. Wildernest addresses outside town limits permit through the Summit County Building Inspection Department in Frisco instead, so we confirm jurisdiction before anything is drawn.
Wildernest, Three Peaks, and Angler Mountain Ranch all have active HOA design-review boards, and we get that approval first. Silverthorne is Summit Fire & EMS territory; the county's Colorado Wildfire Resiliency Code, with Class 2 hardening and ignition-resistant deck surfaces, applies to county permits after May 4, 2026, and we confirm the town's adoption status for each project. The Summit County page covers the county-wide rules.
Snow load: confirmed, not assumed
The town does not publish a single design snow load on its Building Codes page, so we confirm the figure with CBCS before engineering. For reference, Summit County's matrix lists the nearby unincorporated Wildernest subdivisions at 80 psf, with a 40-inch frost depth and a 115 mph design wind. A covered deck or patio cover here is engineered to that class of load: heavier beams, closer post spacing, and footings sized for both the snow bearing down and the wind pulling up. Our guide to how much snow a deck can hold explains the arithmetic.
Steep lots, composite surfaces
West-facing hillsides in Wildernest and Mesa Cortina mean elevated decks with real structure underneath — stepped footings, taller posts, and the budget's center of gravity below the deck boards. Capped composite shrugs off altitude UV, freeze-thaw, and a snowpack that sits for months here, and where the ignition-resistant surface rule applies it is the code-aligned material. Cable or slim aluminum railing keeps the Gore Range in the picture.
Repair or replace
Plenty of Wildernest and Mesa Cortina decks date from the original construction and were framed to lighter assumptions. We inspect before we quote: sound framing gets a repair or re-deck, and an undersized frame gets a replacement built to current numbers. Either answer comes in writing.
An hour and forty minutes, in blocks
From our shop in Centennial, Silverthorne is about an hour and forty minutes via I-70 and the Eisenhower Tunnel. We schedule mountain work in consecutive-day blocks, and for second-home owners we coordinate with your property manager for access and photo updates. The town's 7 am–7 pm, Monday-through-Saturday construction hours suit that schedule, and neighbors in Dillon and Frisco get the same approach — the drive changes nothing about the guarantee.
