Deck Building in Edgewater, CO

Deck building in Edgewater is governed by a specific size-and-height exemption at the low end, and by the full CommunityCore permit process — plus the region’s frost line — at every other size. Knowing which side of that line a design falls on changes both the paperwork and how deep the footings need to go.

The Small-Deck Exemption

Edgewater exempts a deck from a building permit when it meets all four conditions at once: it does not exceed 200 square feet in area, it is not more than 30 inches above grade at any point, it is not attached to the dwelling, and it does not serve the required exit door under IRC Section R311.4. A small, low, freestanding platform deck can meet that description; most decks homeowners actually picture do not.

A deck attached to the house, one that rises more than 30 inches above grade anywhere along its perimeter, one over 200 square feet, or one that serves as the required exit from the home needs a CommunityCore permit before construction starts. We measure height at the deck’s highest point above grade, not an average, since a sloped yard can push one corner of an otherwise low deck past the 30-inch line.

Footings and the Front Range Frost Line

Edgewater’s building regulations put the local frost line at 3 feet (36 inches), meaning footings generally need to bear below 36 inches of finished grade to resist frost heave. That figure reached us through an indexed reference to the city’s building regulations chapter rather than a page we could read directly in full, so we confirm the exact required footing depth with Community Development or SAFEbuilt before finalizing engineering on a given deck, particularly where soil conditions or an engineered footing table might call for something different from the general frost-line figure.

Undersized or shallow footings are one of the most common reasons an older Front Range deck ends up leaning or heaving after a hard winter, so we do not treat the frost-depth question as optional even on a deck that might otherwise qualify for the size exemption above.

Guardrails, Stairs, and What the City Hasn’t Published Separately

We have not found an Edgewater-specific deck bulletin covering guardrail height, baluster spacing, or stair rise-and-run figures. Those requirements come from the adopted 2021 International Residential Code‘s guard and stair provisions rather than a stand-alone city handout, and we build to that code edition’s current figures rather than an older or generic number, confirming with Community Development if a design detail is unclear.

A permitted deck over 30 inches above grade needs a guard along any open side, and any deck with a stair needs handrails and stair geometry that meet the adopted code — we treat those as non-negotiable regardless of whether the deck happens to also clear the 200-square-foot exemption on area alone, since the exemption is about the permit, not about safety code compliance.

Setbacks and Submittal

Edgewater’s general zoning setback rules — a 10-foot minimum rear-yard depth for principal buildings, with different figures where the rear abuts a public alley or street — are documented in Chapter 16 of the Municipal Code. Whether an uncovered deck is treated the same as a principal building for setback purposes, or qualifies for a reduced accessory-structure setback under Edgewater’s own code, is something we were not able to confirm in this research pass; we check the specific lot’s Address Zoning Map result and confirm with Community Development before finalizing a deck’s footprint near a rear or side property line.

Where a permit is required, the submittal generally needs a site plan, a framing or floor plan, and a section view showing footing depth and guard/stair details, filed through CommunityCore along with the value-based fee, the materials use tax, and a 65% plan-review fee where plans are required.

Before the First Footing Is Dug

Because a deck project always involves digging, Colorado law requires requesting a utility locate through Colorado 811 at least three business days before digging begins, so that any underground utility lines on the property can be marked. We build that into the schedule before footing layout starts, on both permitted and exempt decks.

How We Sequence a Edgewater Deck Project

We start by confirming whether the design qualifies for the small-deck exemption or needs a CommunityCore permit, based on square footage, height above grade at every point, attachment to the house, and exit-door function. For a permitted deck, we prepare the site plan, framing plan, and section view before filing, and we request a Colorado 811 locate before any layout stakes go in the ground.

Once utilities are marked, footings are dug to the confirmed depth below the frost line, framing follows, and guardrail and stair details are built to the adopted 2021 IRC figures. Where an inspection is required, we schedule it at the point the permit record calls for review, keeping structural framing and footing depth visible before decking boards close the assembly.

Common Questions

Do I need a permit to build a deck in Edgewater?
Not if it meets all four exemption conditions at once: 200 square feet or less, no more than 30 inches above grade at any point, not attached to the house, and not serving the required exit door. Anything larger, higher, attached, or exit-serving needs a CommunityCore permit.

How deep do deck footings need to go in Edgewater?
Edgewater’s building regulations put the frost line at 3 feet (36 inches), so footings generally need to bear below that depth. We confirm the exact figure for a specific project with Community Development or SAFEbuilt before finalizing footing design.

What guardrail and stair rules apply to an Edgewater deck?
We have not found a stand-alone Edgewater deck bulletin; guardrail height, baluster spacing, and stair geometry follow the adopted 2021 International Residential Code’s guard and stair provisions.

Do I need to call 811 before digging deck footings?
Yes. Colorado law requires requesting a utility locate through Colorado 811 at least three business days before digging, on both permitted and exempt decks.
