The Highlands Ranch Community Association (HRCA) requires prior Architectural Committee approval of exterior improvements. Its home-improvement request lists decks, whether new, replacement, extended or repaired, with a $40 fee, a wide-angle photo, elevation drawings and a site plan. Non-conforming submittals can be denied, and HRCA's architectural committee meets on the first and third Wednesday of the month.
HRCA's Residential Improvement Guidelines, adopted in October 2024, cover decks, deck covers and pergolas. Read the current version before you settle on a design, and confirm fees and requirements with HRCA, since they can change. Our HOA deck approval guide explains how to prepare a submittal.
Step two: a Douglas County building permit
Because Highlands Ranch is unincorporated, deck permits generally come from the Douglas County Building Division; check the county address lookup to confirm for your lot. The county's deck page asks for an application, scaled plans, a site plan showing distances to property lines, and any egress windows or window wells under the deck. Douglas County recommends HOA or architectural approval before you apply. Contractors pulling county permits must be registered with the Building Division.
The 2025 Colorado Wildfire Resiliency Code applies in the county's fire intensity class 1 and 2 areas. If your home is in a mapped wildland-urban interface area, your city or county may require ignition-resistant decking. Your contractor and building department can confirm.

Highlands Ranch homes by the numbers
ACS 2024 5-year estimates show 78.1% of Highlands Ranch homes are owner-occupied and 74.9% are single-family detached. The median home was built in 1997, the median home value is $712,700, and the median household income is $159,307.
With the median home now nearly 30 years old, many original wood decks are due for replacement or refinishing, and owners often add pergolas or switch to composite boards. Each change still needs HRCA approval.

Highlands Ranch deck questions
Do I need HRCA approval to build a deck in Highlands Ranch?
Yes. The Highlands Ranch Community Association requires prior architectural approval for improvements, and its home-improvement request covers new, replacement, extended or repaired decks. The request lists a $40 fee, a wide-angle photo, elevation drawings and a site plan, and incomplete or non-conforming submittals can be denied. Confirm current requirements with HRCA before you apply.
Who issues deck permits in Highlands Ranch?
Highlands Ranch is unincorporated, so deck permits generally come from the Douglas County Building Division rather than a city. The county asks for an application, scaled plans, a site plan to the property lines, and any egress windows or window wells under the deck. Check the county's address lookup to confirm. This is general information, not legal advice.
Which comes first, HRCA approval or the county permit?
Douglas County recommends getting HOA or architectural committee approval before applying for the permit, so in Highlands Ranch that usually means HRCA first. Approved drawings then feed into the county submittal. Building both steps into the schedule matters most around March and September, when searches for deck builders peak.
