Nearby cities, when the rules differ

Aurora's sewer tap rule does not follow you across a city limit. These cities were written from their own permit or utility pages. A town that is only a point on a map is not given Aurora's sentences.

Centennial does not provide water or sewer. A house water heater is one-stop. An addition is not. See also Centennial water heater replacement.
Parker permits inside the town. The district's service-line boundary is not settled on that page.
Highlands Ranch uses Douglas County, not a city building department.
Castle Rock reviews tankless heaters with a gas-load sheet. See Castle Rock tankless installation.
Lakewood has many districts. The city sewer graphic is only the north-side utility.
Arvada says you maintain the service line on your property, and stops there.
Englewood permits water heaters and water-line changes. A 2024 ownership proposal was not treated as current law.
Littleton owners keep the sewer line including the tap. Denver Water supplies drinking water.
Westminster owners keep the lateral to the main, including under a driveway.

Greenwood Village makes you find the district on a map before the permit.
Lone Tree does not sell water. Southgate, Parker Water, and Northern Douglas County Water can each apply. The bill controls. The building permit stays with the city.

Edgewater runs its water utility and splits sewer with East Jefferson Sanitation District.
Sheridan requires a water-heater permit visible from the street.
Foxfield is its own town, with water heaters on a one-stop list.
Bow Mar files building permits through Columbine Valley.
Columbine Valley is the building counter Bow Mar uses.
Cherry Hills Village has a sanitation district, and some taps are also inspected by Englewood.
Watkins is a census place in both Adams County and Arapahoe County. The ZIP code is not the permit office.
Bennett is a town in both Adams County and Arapahoe County. Mail can fall outside the town.
Strasburg is a census place in both Adams County and Arapahoe County, not a city.
Byers is a census place in Arapahoe County, not Adams County. A Byers ZIP still needs a parcel check.
Elizabeth permits only inside town. Many Elizabeth addresses are Elbert County.
Cherry Creek CDP is Arapahoe County, not Denver's Cherry Creek neighborhood.
Four Square Mile is an Arapahoe County census area, not Aurora.
Franktown is Douglas County, and it is not on Pinery Water's community list.
Sedalia has a water district whose primary published service is water, not a census-wide sewer.
The Pinery is Pinery Water's community, not a stand-in for the other Douglas places.
Stonegate is Stonegate Village Metropolitan District where the bill says so, not the Town of Parker.
Meridian is Meridian Metropolitan District for its customers, not the City of Lone Tree.
Roxborough Park is Douglas County. Roxborough Water's central, east, and west areas are not the same service.
Evergreen uses Jefferson County, with a well or a district proved on Form 1001.
Golden permits water heaters and water or sewer utility repairs, after an address check that the municipal status is Golden.
Morrison contracts inspections to Charles Abbott Associates. Confirm the utility on the bill before street work.
Erie reviews a water heater in one to two business days.
Lafayette distinguishes a water-heater repair from a replacement.
Superior takes permits only through CommunityCore. SAFEbuilt inspects.
Boulder treats water heaters as mechanical permits and can exempt a simple stoppage.

A Census point within 50 straight-line miles is not a promise that a plumber will come, and it is not drive time. Denver's lead program is a guide, not a city hub, because eligibility is an address search. If your mail says Aurora and the parcel is not, confirm the city before you use Aurora's sewer page.
