Parker Deck Permits: Every Deck, Any Height

Ask around the metro whether a low deck needs a permit and you'll get different answers, because the rules really do differ. In Denver, an uncovered deck 12 inches or less off the ground doesn't need a permit unless the property is a landmark or in a historic district. In Parker, the answer is simple: permits are required for all decks regardless of height or size. A ground-level platform behind a townhome needs one just as much as a second-story deck off a walkout.

What Parker's rule covers

Parker's guidance lists decks alongside other projects that always need permits, including basement finishes, additions, remodels, radon systems, water heater, furnace and AC replacements, window, door and siding replacements, retaining or block walls over 48 inches and fences over 6 feet. The town's general advice to homeowners is that permits are required for almost everything, so check before starting any project.

Practically, that means:

• Replacing an old deck needs a permit, even if you rebuild the same footprint.
• Low platform decks and freestanding decks need permits, too.
• Plan submittal is generally required, though staff can tell you whether a particular project is exempt from some submittal items.

EZ Permits: help for DIY builders

Parker runs an EZ Permits program aimed at homeowners doing their own projects, such as decks, basements and covers. You call the Building Division to set up a meeting, staff help you work through the permitting system, and the stated goal is that you walk out the door with your permit in hand. The town also publishes a homeowner fee estimator worksheet so you can budget permit fees before you apply.

For a homeowner who's comfortable with framing but new to permit drawings, an EZ Permits meeting is worth booking before you buy lumber. Bring a site plan with distances to property lines, the deck's height, footing locations and a framing plan with joist and beam sizes.

HOA first, then the town

Most Parker neighborhoods are covenant-controlled, and HOAs typically review deck size, location, railing style, materials and colors. Get written HOA approval before you apply for the permit, and design to the HOA's material rules from the start. Many associations favor or require specific composite colors or railing styles.

Designing for Parker lots

Parker's subdivisions include many walkout and garden-level lots, which produce tall decks that need:

• footings sized for the load and set below frost depth, with engineer input on expansive soils;
• a ledger bolted and flashed at the rim joist;
• bracing and guards for height;
• stairs and landings that fit setbacks.

Strong sun on the plains favors capped composite or PVC decking in lighter colors, which stay cooler and fade less than dark boards.

Castle Rock

Castle Rock, next door, runs its own building division with residential permits submitted through its online portal. Homeowners doing their own work there use a homeowner affidavit. Check the town's residential permits page for deck submittal requirements before you design. See the Parker and Castle Rock area page for both towns' permit systems.
