Landscape lighting in Highlands Ranch
Highlands Ranch is unincorporated Douglas County with about 103,000 people (2020 Census), and the HRCA guidelines decide what lighting goes in.
How this works: Highlands Ranch Lighting is a free referral service, not a lighting contractor. We pass your request to independent local lighting installers, who may pay us for the referral. They quote, schedule and do the work; check their insurance before you hire. More about us.
HRCA approval comes first
The HRCA's Residential Improvement Guidelines (adopted October 2024) require Architectural Review Committee approval for new or replacement exterior fixtures, landscape and accent lighting and permanent eave lights included. The submittal needs images and specs of the fixtures and photos showing placement.
The limits
Landscape and accent fixtures must be low voltage. House-mounted decorative fixtures are capped at 500 lumens and security fixtures at 1,000 lumens, no higher than 10 feet. Backyard string lights need no approval if they stay at or under 2700K and about 250 lumens, at least 5 feet from property lines, and off by 11 pm. Holiday lights need no approval and must be off by 11 pm.
County guidance
Douglas County's dark-sky page discourages uplighting trees and suggests fully shielded fixtures at 3000K or lower. HRCA's own rule is that every light cone stays inside the property without glare.
Prices
Denver Landscape Lighting's Highlands Ranch page says simple entry lighting typically starts around $1,000 and full-property designs run $3,500 to $10,000+. Angi's 2026 average is $3,500.
