Tips
- Water heater replacement (like-for-like) and residential sewer line replacement are One-Stop Permits — no plan review, issued the same business day, per the City's Building Permit Review Schedule.
- 'Miscellaneous' plumbing work not classified as One-Stop is reviewed in 5 business days for residential projects per the Review Schedule.
- Colorado's statewide energy-code floor (HB22-1362) does not set plumbing-fixture standards; Centennial's own adopted 2021 IPC governs fixture and venting requirements, distinct from the UPC used in some other Mountain West jurisdictions.
