Bathroom remodeling in Centennial runs through the city’s Building Division, and the permit category depends on how much of the room is changing. A fixture swap can be treated differently from a bathroom that moves plumbing or changes the footprint. Our crew starts by separating replacement work from alteration work so the permit submittal matches what will actually be built.
Fixture Replacement and Room Alteration Are Different Paths
Centennial allows fixture-replacement-only work, such as swapping a toilet, tub, or vanity without moving plumbing, to fit the One-Stop Permit path. Work that relocates plumbing or changes the room’s footprint is treated as a Residential Alteration. That distinction is important because many bathroom projects begin as finish updates and become alteration work once the floor, walls, or plumbing layout changes.
We define that scope before demolition. If the vanity stays in place and fixtures are replaced in kind, the permit conversation is narrower. If drains, supplies, walls, or the room shape move, we plan for alteration review and rough-in inspection readiness instead of pretending the job is only a fixture swap.
Bathroom Plans Need Materials and Fixture Locations
Centennial’s residential plan checklist calls for bathroom plans to show bathroom dimensions, plumbing fixture locations, and the wall and floor surface materials that will be installed. That changes how we prepare the job. The city is not just looking for a label that says bathroom remodel; it wants to see where the fixtures go and what surfaces are part of the room.
For the build, those details matter too. Tile backing, wet-area surfaces, vanity placement, tub or shower location, and flooring transitions all have to be coordinated before walls close. Our crew uses the permit plan as a construction reference so the finished bathroom matches the layout and materials the city reviewed.
Electrical Protection Must Be Shown on the Plan
The Centennial checklist requires GFCI receptacle locations and required arc-fault protected circuits to be shown on power floor plans for permitted work. Bathroom remodels commonly affect outlets, lighting, switches, fans, and vanity wiring, so we treat the electrical layout as part of the permit package. It is not a detail to leave until trim-out.
In the field, that means the wall framing, vanity selection, mirror layout, and electrical rough-in have to agree. A receptacle that looks fine on an old wall can conflict with a new vanity bank or medicine cabinet. We coordinate those items before rough work so inspection and finish installation are not fighting each other.
Complete Submittals Keep the Review Moving
When a bathroom remodel relocates plumbing or alters the footprint, Centennial reviews it as a Residential Alteration in 5 business days from complete submittal. The review clock depends on a complete package, so missing fixture locations, material notes, or power-plan information can slow down the project before construction begins.
Our crew prepares the bathroom scope with the city checklist in mind. We show the affected room, the fixtures, the surface materials, and the electrical information that applies to the permitted work. That gives the Building Division a clearer basis for review and gives the field crew the same plan the city approved.
How We Sequence a Centennial Bathroom Remodel
The sequence starts with classifying the work as fixture replacement or alteration. For alteration work, we prepare the plan set, submit through Centennial, and wait for the approved permit before opening walls or floors. Demolition then leads into plumbing and electrical rough-in, inspection readiness, surface installation, fixture setting, and final closeout.
Centennial’s requirements make early decisions more important than late corrections. Moving a toilet, changing a tub to a shower, or rebuilding wet-area surfaces can affect the permit path and the plan details. We keep selections, drawings, and field work coordinated so the bathroom is built as reviewed.

Common Questions
No. Fixture replacement without moving plumbing may use a One-Stop Permit, while plumbing relocation or footprint changes are Residential Alterations.
Plans for bathroom work must show bathroom dimensions, plumbing fixture locations, and the wall and floor surface materials to be installed. Power plans must also show GFCI receptacle locations and required arc-fault protected circuits.
Residential Alterations are reviewed in 5 business days from complete submittal. We prepare the plan package so the city can see the room layout and affected systems.
