Highlands Ranch conditions
Highlands Ranch is a master-planned suburb developed from the 1980s onward, made up of developer-named subdivisions, and it is the largest community in Douglas County and the most populous unincorporated community in Colorado. No city government means permits come from the Douglas County Building Division, whose Plumbing/Mechanical permit application lists gas and electric water heaters. For some projects, the Highlands Ranch Metro District says its own approval comes before the county will issue a building permit.
A gas utility for Highlands Ranch was not confirmed from an official page for this site, so check your gas bill for the utility name and emergency number.
Homes from the earlier phases of development have now been through one or two furnace and water heater replacements, and finished basements often hide gas lines that were extended for a bar, fireplace or second furnace. Newer phases are more likely to have flexible tubing.
Checklist before the visit
- Find the meter and the main shutoff
- Clear access to the furnace room and water heater
- Have the model of any new appliance, especially a tankless heater
- Know whether a basement finish covers the gas lines
- Check whether your project needs Metro District approval
Late summer and early fall are good times for planned work, ahead of steady furnace use. If you are planning a tankless upgrade, do it before the old tank fails so the line sizing and permit are not rushed.
