Larkspur, CO · Family-owned
Owner-built by Jon & Janessa LangDecks for Larkspur lots, in town or out in Perry Park. Sized to the county snow table, built to the wildfire rules, and set clear of the septic field. Built by Jon & Janessa Lang.
Two permit offices, one ZIP code
The Town of Larkspur is small. It covers about 1.59 square miles along I-25 and counted 206 people in 2020. Plenty of homes with a Larkspur address sit outside it, in places like Perry Park, which is unincorporated Douglas County. That one line on the map decides who reviews your deck.
Inside town limits, the town issues the permit and SAFEbuilt does the plan review and inspections, under the 2018 codes the town adopted in Ordinance 2022-11. Outside town limits, your deck plans go to the Douglas County Building Division in Castle Rock. The town posts a street list on its Building Department page so you can tell which side you are on. We check it before we draw a single board. For the bigger picture on building out here, see our Larkspur service area page.
“After researching several local companies, they were the clear winner. The quality far exceeded the cost, craftsmanship in every square inch.”
Dale Maxey · Custom deckWhat changes a Larkspur deck
None of these are hunches. Each comes from a county, town or district rule, and each one changes what we build and what it costs.
Douglas County sets snow load by how high your lot sits. It is 30 pounds per square foot below 6,000 feet, 35 from 6,000 to 6,499, 40 from 6,500 to 6,999, and 45 from 7,000 to 7,499. For a cover over the deck, the county will not let the roof number drop below the ground number. Perry Park is listed at 6,493 feet, right at a line, so we check your lot and not a town average.
The red rocks around Perry Park are Fountain Formation sandstone at the foot of the Rampart Range. Dig there and you may hit rock. The county also wants footings at least 36 inches below finished grade for frost. We plan the footing layout around what the ground allows and show every footing on the plans.
The county's deck page says lots in fire intensity class 1 or 2 fall under the 2025 Colorado Wildfire Resiliency Code. For an open deck, the walking surface has to be noncombustible, Class A, fire-retardant-treated wood, or ignition-resistant. Composite boards rated Class B or better are allowed. We check your parcel and confirm with the county and your fire district which rules apply.
Some homes near Larkspur get water and sewer from the Perry Park Water and Sanitation District. Others run on a septic system. The county says finding utilities before digging is up to the owner, so we pull your septic permit from the county's OWTS map and get lines marked before any hole goes in.
“The inspector was impressed by their system and mentioned this deck is built to withstand a hurricane.”
Dominic ValenzuelaLarkspur deck jobs we get asked about
These are the deck jobs that come up most around Larkspur, and how the local rules shape each one.
Perry Park began as John D. Perry's 4,000-acre ranch, bought in 1870. Today homes sit among red sandstone and slope. A deck there often has to step around rock. We place each post where its footing can reach good ground and keep the frame close to grade where the lot lets us.
The wildfire code calls the first five feet around a house the Immediate Zone. It asks for rock, gravel, concrete or pavers there, with no shrubs or wood mulch. The ground at the edge of your deck is part of that zone, so we finish it to match.
Want shade over the deck? The county treats a solid cover as a roof. It needs a permit and must carry the full snow load for your elevation. An open pergola that does not hold a uniform snow load is exempt from the permit. We price both so you can pick.
Perry Park was one of the first places in the country named a Firewise Community, back in 2002. Neighbors clear brush and use the district's slash pickup twice a year. A new deck should help, not hurt. We use boards that meet the wildfire rule and add metal flashing where the deck meets the wall.
The county says to leave a septic soil treatment area mostly untouched, since packing it down can make it fail early. So we keep posts, footings and heavy gear off it. If the county map has no record for your system, a licensed installer or inspector can find it first.
Dawson Butte rises to 7,474 feet about five miles south of Castle Rock, and Perry Park sits at the foot of the Rampart Range. If a view is why you bought the lot, we pick a slim rail so you see the land and not the railing.
Verified customer reviews
These are word-for-word Google reviews from deck customers. Notice how often they mention a crew that showed up when it said it would.
“We had them tear out our very old deck and build a new much bigger deck. They are VERY focused on quality builds! They showed up every day exactly when they said they would. Our new deck is AWESOME! We love the Timber Tech product as well.”
“We had Jon, Andrew, and Derrick rebuild our deck. The crew was always on time, hardworking, polite and professional. He built a cozy deck for us and completely delivered on all his promises. The deck matches our yard very well and we enjoy it everyday!”
“We chose to do a picture-frame design with black railing. Jon was very easy to work with and always on time. Very happy! Would do business again with him and highly recommend them!”
