Do You Need a Permit to Remodel a Bathroom in Denver

It depends on what you’re changing. A cosmetic bathroom refresh in Denver — new paint, a vanity or toilet swapped in the same spot, re-tiling, or replacing a faucet — usually doesn’t need a building permit. You cross into permit territory once you move or add plumbing or electrical, relocate fixtures, change the layout, remove or move a wall, or add square footage. Because remodels often bundle plumbing and electrical work, many projects need those trade permits even when the building permit is borderline. Check the specifics with the Denver Community Planning and Development; the requirements above outline what Denver treats as permit-worthy.

What Bathroom Work Needs a Permit in Denver

In Denver, the trigger is usually moving systems, not refreshing surfaces. Work that typically requires a permit: relocating or adding plumbing (moving a toilet, sink, or shower drain), adding a shower or tub where there wasn’t one, new or moved electrical circuits and outlets, removing or altering a wall, converting a half bath to a full bath, or turning another room into a bathroom. Like-for-like swaps in the same location — same toilet spot, same tub footprint — usually don’t. Even removing a tub can need a plumbing permit if the drain is capped or moved, so confirm with the Denver Community Planning and Development before you start.
