Centennial's own schedule
Centennial heater permits versus a remodel
In Centennial a house water heater is on the one-stop list. An addition, a basement finish, and commercial work are not. The city still does not supply your water.
The building review schedule says one-stop permits need no plan review and states one business day for water heaters, gas lines, and residential sewer replacements, among other items. New houses and new commercial buildings are listed at 15 business days after the fee is paid. Residential additions are 10. Basement finishes are five. Those clocks start on a complete submittal. They are not a promise from this website. The hiring page for a house tank is Centennial water heater replacement. The city hub is Centennial.
Districts, not the city, provide water and sewer. Responsibility varies by utility. Confirm the district before you authorize work.
Questions to settle first
Is a water heater one business day?
That is what the city's schedule says for the one-stop list, after a complete submittal. It is a target, not a guarantee, and it is not the 15-day line for a new house. Ask which list the application is on.
Does the same clock cover a basement bath?
No. A basement finish is on the five-business-day residential line in that schedule, and an addition is on the 10-day line. A water heater does not pull the bathroom onto the one-stop list. Ask them to write that limit into the quote before you compare it with another company.
Who owns the water line?
Not the City of Centennial. The city says it does not provide water or sewer. Use the property search to find the district. Aurora's owner-to-the-main sentence is the wrong city. Ask them to write that limit into the quote before you compare it with another company.
