Henderson is an unincorporated Adams County community where parts of the area have been annexed by Commerce City, Brighton and Thornton, so your water and sewer provider and your permit office depend on the exact address.

Unincorporated Adams County, about 14 miles out
Henderson has had a post office since 1894, and a few older buildings still line Brighton Road north of 120th Avenue. It has no town government; Adams County names it among its unincorporated communities. The center is about 14 miles from downtown Denver in a straight line, and Brighton is the nearest larger city. The Adams County Regional Park and Fairgrounds is close by. Over the years Commerce City, Brighton and Thornton have annexed much of the surrounding land, so neighbors with the same 80640 ZIP code can fall under different governments.
Water and sewer: check your bill
We could not pin down a single water or sewer provider for Henderson homes, and we will not guess. Annexed parcels may be on a city system or a city-area district, while unincorporated homes may be served by a small district. One example is Hazeltine Heights Water and Sanitation District, a domestic water district with a Henderson mailing address and a well house on East 104th Avenue; it makes its customers responsible for the service line from the downstream side of the meter pit to the house and for any required backflow devices. It does not publish a service-area description, so do not assume it serves you.
Likewise, South Adams County Water and Sanitation District's Williams Monaco Wastewater Treatment Plant stands at 9702 Monaco Street in Henderson, but that location does not tell you whether your home is on that district's sewer. Your water and sewer bill names your provider. If you have no bill or are buying a property, Adams County can help you find out.
Permits from Adams County or a city
For unincorporated addresses, permits come from Adams County Community and Economic Development, at the One Stop Permitting Center and Building Safety, in the Government Center at 4430 South Adams County Parkway in Brighton (720-523-6800). The County requires a building permit to install or replace a water heater and for plumbing modifications, and contractors working in unincorporated Adams County must be registered with the County. If your parcel has been annexed, the permit comes from Commerce City, Brighton or Thornton instead.
Gas safety
If you smell gas, get out of the house before doing anything else. From outside, call 911 and your gas utility. The utility's name and emergency number are on your gas bill.
How Henderson differs from Denver
In Denver, the city handles permits and Denver Water and the city sewer cover nearly every house. Henderson asks more of the homeowner up front: knowing whether the parcel is annexed, which district bills for water, and which office issues permits. The plumbing itself is familiar. Winter freezes split hose bibs and unprotected lines, water heaters wear out, and drains clog. When you call the number on this page, explain the problem, give your address so the right rules can be checked, and say whether you have shut off the water. You will be connected with an independent plumber who works in the Henderson area, and you agree on price and timing directly.
