Building a deck in the Town of Castle Rock comes with a few steps: a permit through the Town's online portal, a registered contractor, and, in many neighborhoods, an HOA sign-off too. Here's the plain-English walkthrough so nothing catches you by surprise.
When you need a permit
In Castle Rock, decks need a building permit. The Town's own page says a permit is required for any work that affects the building, and it lists decks by name. A normal backyard deck, bolted to the house, up off the grade, with a door onto it, needs a permit every single time. When in doubt, assume you need it.
Meet eTRAKiT, the online portal
Castle Rock runs its permits through an online system called eTRAKiT. It's open 24/7, and it's where the whole permit lives. Through eTRAKiT you (or your builder) will:
- Apply for the deck permit.
- Upload a site plan showing the setback from the edge of the deck to each property line.
- Upload framing drawings, the size and spacing of your footings, posts, beams, joists, and the ledger detail where the deck attaches to the house.
- Read and respond to the plan reviewer's comments.
- Pay the fees and schedule your inspections.
One catch that trips up homeowners: your contractor has to be registered with the Town before they can pull a permit. A builder who isn't registered with Castle Rock can't even start your application.
Don't want to learn eTRAKiT? We're registered with the Town, we draw the plans, and we pull the permit for you, it's all in your free, itemized estimate.

Everything permit-related runs through the Castle Rock Building Division. If you ever need to ask a question about your deck, the number is 720-733-3527. They handle the registration, the plan review, and the inspections. Honestly, you shouldn't have to call them at all if your builder is handling the permit, but it's good to know where it lives.
Your HOA is a separate "yes"
The Town permit and your HOA approval are two different things, and in many Castle Rock neighborhoods you need both. Many HOAs have an architectural review committee that checks your plans, materials, and even colors. One example:
- The Village at Castle Pines has Castle Rock addresses but sits in unincorporated Douglas County. Its Design Review Committee must sign off on decks, patios, patio covers, hot tubs, and fire pits, and it meets once a month.
So we start the HOA review early and submit it clean so it's approved the first time.
Watch out: not every "Castle Rock" address is in town
This one catches people. Communities like Bell Mountain Ranch and Keene Ranch have a Castle Rock mailing address but actually sit in unincorporated Douglas County, outside Town limits. If that's you, your permit comes from the Douglas County Building Division, not the Town of Castle Rock, and the rules and portal are different. We check the exact address first so we apply to the right office and your project doesn't stall on day one.
Inspections and timeline
Once the permit is issued, the Town inspects the work as it goes, typically the footing holes before concrete (so they can confirm you've gone deep enough for our clay soil), then the framing, then a final once it's done. You schedule each one right in eTRAKiT.
For timing, the permit and the HOA review are separate steps, so we start both early. That's how we keep the whole job on schedule.
Bottom line: a Castle Rock deck means a permit through eTRAKiT, a registered builder, and an HOA sign-off in many neighborhoods. Want it handled start to finish? See our deck installation in Castle Rock page, or learn more about how we work across Castle Rock.
