Deck Building in Sheridan, CO

Sheridan does not publish a separate deck-building guide the way some neighboring cities do. A new deck goes through the same general Building Permit Application and contractor-licensing process as other residential construction, governed by the adopted 2021 International Residential Code, without a Sheridan-specific handout spelling out deck guard heights, stair geometry, or footing depth. That makes it a project where confirming details directly with the Building Department matters more than it does on a trade with its own published sheet.

No Separate Deck Guide — the General Permit Process Applies

A deck in Sheridan is permitted through the same Building Permit Application used for additions and other structural work, not through an over-the-counter category the way roofing or siding is. That means a full plan submission is the expected path rather than a same-visit filing, and the application’s general residential fields, valuation, scope of work, contractor information, cover a deck the same way they cover other construction.

We prepare a plan set that shows the deck’s footprint, framing, footing locations, and attachment to the house, since that is the level of detail a plan-review permit needs even without a deck-specific city form to fill in the blanks for us.

The Adopted 2021 IRC Governs Deck Structure

Sheridan has adopted the 2021 International Residential Code city-wide for one- and two-family dwellings, and that code edition is what governs a deck’s structural design, framing, and connections in the absence of a Sheridan-specific amendment. We did not find any Sheridan amendment to the IRC’s deck provisions published separately from the general code adoption.

Because we could not independently verify the IRC’s specific prescriptive deck tables, such as beam spans or joist spacing, against Sheridan’s currently adopted code edition through an accessible official source, we do not publish those figures here as if they were confirmed for this jurisdiction. Structural sizing is worked out against the current adopted code at the plan-review stage rather than assumed from a generic figure.

Setbacks: What We Know and What We Do Not

Sheridan’s Zoning Code sets standard yard setbacks for the principal structure on a Residential Single-Family lot: a rear setback of at least 20 feet, a front setback of at least 20 feet, and a side setback of at least 5 feet, increasing by 6 inches for every foot of height above 15 feet on lots 40 feet wide or greater, or a minimum 3-foot side setback on narrower lots. We did not find a Sheridan zoning provision that specifically addresses whether a deck is treated as part of the principal structure for setback purposes or is allowed some separate exception the way a covered patio sometimes is in other jurisdictions.

Our working assumption, stated plainly as our own inference rather than a published city rule, is that a deck should be designed to meet the same yard setbacks as the house itself unless the Zoning Administrator confirms otherwise for a specific property. We raise that question with the city directly before finalizing a deck layout that sits close to a property line.

Footings, Frost Depth, and Why We Confirm Locally

We were not able to find a published Sheridan-specific frost depth or footing-depth requirement for residential decks. Frost depth requirements are typically set locally along Colorado’s Front Range, and Sheridan’s adopted 2021 IRC establishes the framework, but the specific depth applied in practice is confirmed with the Building Department at plan review rather than assumed from a regional average.

We do not install deck footings to a guessed depth on a Sheridan project. The footing depth used on site is the one confirmed through the permit process for that specific location, and we build the schedule around getting that confirmation before excavation rather than after.

Guards, Stairs, and Ledger Attachment

Guard, stair, and ledger-attachment requirements for a Sheridan deck are governed by the adopted 2021 IRC’s general residential provisions, since no Sheridan-specific deck handout sets out separate numbers for these details the way some neighboring cities publish. We did not verify the IRC’s specific guard-height trigger or stair geometry figures against an accessible official Sheridan or ICC source for this project, so we do not state those numbers here as confirmed for this jurisdiction; they are worked out against the current adopted code at plan review.

Ledger attachment to the house, where the deck is not a freestanding structure, is one of the details plan review and inspection focus on closely, since an improperly fastened ledger is a common structural failure point on residential decks generally. We treat that connection as a plan-review item to get right on paper before it is built, not a field decision.

Licensing and Fees

Sheridan’s fee schedule lists a Carpentry contractor license, currently $140, as the category that would generally apply to deck-building work absent a more specific deck category on the city’s list. Plan review fees on a Sheridan building permit are calculated as 65% of the permit fee itself, consistent with how plan review is priced across other permitted residential projects in the city, and the same doubled-fee consequence for starting work before permit issuance applies here as it does on every other Sheridan permit.

We do not claim Apollo holds a Sheridan-issued contractor license; the license requirement described here is the city’s own, confirmed at the time a specific project’s permit is filed.

How We Sequence a Sheridan Deck Project

We start by confirming the deck’s footprint against the house’s existing yard setbacks, treating the deck as bound by those same setback lines unless the Zoning Administrator says otherwise for the specific lot. Plan preparation covers framing, footing locations, ledger attachment, and guard and stair layout, submitted as a full plan set rather than filed over the counter.

Once the permit is issued, footing excavation and inspection come first, at the depth confirmed through plan review rather than a generic assumption, followed by framing, ledger connection, decking, and guard and stair installation, with final inspection closing out the project. We keep footing work visible for inspection before it is backfilled, the same discipline the city expects on any structural foundation element.

Common Questions

Does Sheridan have a separate deck-permit guide?
No. A deck goes through the general Building Permit Application and full plan-review process, governed by the adopted 2021 IRC, without a Sheridan-specific deck handout.

Do Sheridan’s yard setbacks apply to a deck?
We did not find a published rule addressing decks specifically. Our working approach is to design the deck to meet the same setbacks as the house, rear and front at least 20 feet and side at least 5 feet, unless the Zoning Administrator confirms an exception for the property.

What footing depth does a Sheridan deck need?
No Sheridan-specific frost or footing depth figure is published for decks. We confirm the required depth with the Building Department at plan review for the specific site before excavating.

What license covers deck-building in Sheridan?
The city’s fee schedule lists a Carpentry contractor license, currently $140, as the category that generally applies absent a more specific deck category.
