City of Thornton
Plumber Thornton CO
Thornton separates a building permit from a right-of-way permit for a water or sewer service repair. An in-yard repair inside the city is not the same application as a repair that reaches the street.
Two counters
The city's permit portal says a building permit is required to erect, enlarge, remodel, repair, or change a building or utility. Building Inspections is 303-538-7250. Homeowners working on their own residence are not licensed as contractors. Separately, sewer and water service repairs that run from the yard into the right of way, inside city limits, use a sewer and water service construction permit. Repairs that stay in the yard, inside city limits, go to the Buildings Division. Outside city limits, the portal says an in-yard-only repair is the case that uses the service-construction permit. Read that twice before you apply. A Thornton mailing address is not proof you are inside the city.
What this does not decide
Thornton's permit instructions do not draw an ownership line at a curb or a tap. Westminster's driveway sentence is Westminster's. Ask Thornton utilities, for this address, who maintains the pipe under the asphalt. A water line quote should name which permit, building or right-of-way, is included.
Questions to settle first
Does a yard leak in Thornton need a street permit?
Only if the repair leaves the yard and enters the right of way, and only if the parcel is inside the city. The portal sends in-yard work inside the city to the Buildings Division, and right-of-way service repairs to a different construction permit. Confirm the city limit before you pick the form.
Can I use Aurora's sewer rule?
No. Thornton's pages describe which permit to pull. They do not say the owner keeps the line through the tap the way Aurora Water does. Ask the city's utility for the address. A quote that assumes Aurora's split can bill you for a pipe the city maintains, or the reverse.
Who licenses the plumber?
Thornton licenses contractors who build, alter, or install underground utilities in the city. A homeowner on their own house is not in that license rule. The person who pulls the permit should match the portal's category. Building Inspections is 303-538-7250. That number is the city's, not this guide.
A slow drain is drain cleaning until a camera shows a broken sewer line. A tank swap is water heater replacement. Confirm the permit office and the utility for this address before the work is closed up.
