Rough-in before the walls close
Remodel and addition plumbing in Aurora
Adding a bathroom, moving a kitchen, or finishing a basement is rough-in, inspection, and then fixtures. It is not a Saturday faucet swap.
Sequence
Drains and vents go in while the framing is open. Supply pipes follow. Inspection happens before insulation and drywall cover the work. Aurora's inspections page says the area has to be open and the permit card on site. If the plumber is scheduled after the rock is hung, you are paying to open it again. Ask for the inspection type, often a plumbing rough, and who meets the inspector.
Centennial's review schedule puts residential additions at 10 business days and basement finishes at five, after a complete submittal. A house water heater there can be one-stop. An addition is not that list. See Centennial heater versus remodel. Aurora does not publish that same chart. Use Aurora's permitting page for an Aurora parcel.
What changes the plumbing scope
Every new fixture needs a drain, a vent, and hot and cold water, and the existing pipes have to be large enough. This guide will not calculate fixture units. The plumber should say whether the current building drain and water service can take the new bath. A basement bath below the sewer leaving the house needs a pump. That pump is a sewer ejector, not a groundwater sump.
Keep fixture setting, the tub or shower, and the water heater as their own lines if they are not in this rough-in. Tub and shower work fails when nobody owns the valve access.
Questions to settle first
Can the plumber rough in after drywall?
They can, and then the wall comes back off for the inspection. Aurora wants permitted work open and the permit card on site. Schedule the rough inspection before insulation. Closing early is how you pay twice. Ask them to write that limit into the quote before you compare it with another company.
A basement toilet is below the street sewer. What then?
Gravity will not carry the waste up. The fixture needs a pump, maintained by the owner, which Littleton's code also says for buildings that sit too low. That is an ejector, not a sump pump for groundwater. Ask which basin and where it discharges.
Is an addition the same permit as a water heater?
No. Centennial lists additions on a multi-day review and house water heaters as one-stop. Aurora's same-day language is about replacement heaters, not a new bathroom. Ask which application this drawing is. Ask them to write that limit into the quote before you compare it with another company.
Who buys the fixtures?
Say so. Rough-in can exclude the toilet, the faucet, and the tub, which show up later as a second invoice. If the plumber supplies them, the model numbers belong on the quote so the valve and the trim match.
