Do You Need a Permit for a Bathroom Renovation in Aurora?

Are you planning a bathroom renovation in Aurora and wondering whether the Town requires a building or plumbing permit for your project? One of the first things you should think about before demolition is whether any drain or vent pipes will move. Having a permit in place whenever the scope requires one protects your resale disclosure, keeps your home insurance valid if a pipe ever fails, and brings a municipal building inspector to verify concealed drains before new porcelain tile covers the walls. Below is how the Town of Aurora Building Division separates permit-exempt bathroom refreshes from permitted alterations, with direct links to official municipal and provincial pages.

Bathroom work in Aurora that does not require a building permit

In the Town of Aurora’s “When are Permits Not Required?” guidelines, like-for-like fixture and finish replacements inside an existing bathroom do not require a municipal building permit provided the plumbing piping and structural framing are not modified: Source: Town of Aurora: Applications, Permits and Inspections (When are Permits Not Required?) (accessed November 7, 2026)

• Repairing or replacing existing plumbing fixtures—such as a toilet, basin, faucet, shower valve or bathtub—in the exact same position without altering the drain, waste or vent pipes.
• Replacing bathroom cupboards and vanities without plumbing work, and installing quartz or stone countertops, millwork and mirrors.
• Stripping old ceramic tile, installing waterproof backer board and membrane, and laying new floor and wall finishing.
• Painting, trim carpentry, and replacing an existing exhaust fan or light fixture (electrical wiring is regulated separately through the ESA).

In practical terms, many 3-piece hall full bathroom renovations across Regency Acres, Aurora Village, Aurora Heights, Aurora Highlands and Aurora Grove proceed without a municipal building permit because the toilet remains on its existing floor flange, the vanity connects to the existing wall trap, and the new tub sits in the original 60-inch alcove.

Bathroom work that requires a Town of Aurora building & plumbing permit

The Town of Aurora Building Division requires a permit whenever a renovation adds or alters plumbing drains, vents or supply lines, cuts structural framing, or creates a new bathroom (and the Town notes that a separate Plumbing & Drain Permit Application may be required alongside an alteration permit): Source: Town of Aurora: Plumbing and Drain Permit Application & Building Division Guidelines (accessed November 7, 2026)

• Moving a toilet stack or tub/shower drain, even by a foot or two, because the subfloor drain branch and vent connection must be re-piped.
• Combining a corner whirlpool tub and narrow stall into one relocated walk-in shower in a Bayview Northeast, Bayview Wellington or Bayview Southeast primary ensuite where the drain shifts across the floor.
• Adding a new plumbing fixture, such as installing a freestanding soaking tub alongside a separate shower or splitting a single drain stack into a two-trap double vanity with new vent branches.
• Adding or modifying a basement bathroom—whether saw-cutting the concrete slab for new underground drains, shifting builder rough-in stubs, or registering a second or third dwelling unit.
• Altering structural framing, such as opening a load-bearing partition wall or cutting floor joists to recess a curbless shower pan.

Does a tub-to-shower conversion need a permit in Aurora?

Whether an alcove tub-to-shower conversion requires a Town of Aurora permit depends on what changes beneath the subfloor. Most bathtubs drain through a 1.5-inch P-trap set near one end of the alcove, whereas a dedicated walk-in shower uses a 2-inch drain trap (often shifted to the centre of the shower pan or along one wall for a linear drain). Modifying the trap size or drain location counts as a plumbing alteration requiring a permit. We inspect your existing drain setup during quoting and state clearly in writing whether a permit applies.

Yonge Street, Wellington Street and Bayview Avenue condominiums

If your bathroom is inside a condominium building along Yonge Street, Wellington Street or Bayview Avenue, condo board approval comes before any work begins. Property management requires a signed suite alteration agreement, our written scope of work, our active WSIB clearance certificate, and our commercial liability insurance certificate naming the condominium corporation. Because condo drain traps are cast into the concrete floor slab, fixtures stay in their existing footprints; see our small and condo bathrooms in Aurora page.

How electronic submissions work in the Town of Aurora

The Town of Aurora Building Division uses an electronic plan review process. Permit applications, black-and-white scaled PDF drawings (combined by discipline and named according to the Town’s file naming conventions), and fee payments can be submitted through the Town of Aurora CityView Portal (cvportal.aurora.ca), by email to building@aurora.ca (for files up to 16 MB), or on a USB drive in person at Town Hall (100 John West Way).

Ontario’s consumer protection guidance highlights an important legal point: as the property owner, you are ultimately responsible for ensuring required building permits are in place for work at your house. Source: Government of Ontario: Your rights when starting home renovations or repairs (accessed November 7, 2026) Whenever your contractor handles the permit application as your authorized agent, make sure that task is written into your contract and ask for the issued permit number prior to demolition. See our checklist on how to vet a bathroom contractor in Aurora for what else your contract should state.

Scaled drawings, BCIN designers and municipal inspections

A residential bathroom permit package includes scaled floor plans showing the existing room layout, the proposed fixture locations, framing details, and plumbing drain and vent risers. In Ontario, permit drawings must be drafted either by the property owner or by a designer holding a Building Code Identification Number (BCIN), which you can look up on the provincial QuARTS registry.

Once the Town of Aurora Building Division issues the permit, you or your contractor book a municipal inspection through the CityView Portal, by emailing building.inspection@aurora.ca, or by calling 905-726-4778. The inspector checks the rough-in stage while the subfloor and walls are open and the new drains, vents and supply lines are exposed, prior to closing up with waterproof backer board and tile.

Electrical wiring and the Electrical Safety Authority (ESA)

Municipal building inspectors in Ontario do not inspect residential electrical wiring. All electrical work in an Aurora bathroom—installing wet-rated shower pot lights, wiring an electric radiant floor-heating mat, adding a GFCI receptacle by the vanity, or running a circuit for an exhaust fan—is regulated by the Electrical Safety Authority (ESA). Source: Electrical Safety Authority (accessed November 7, 2026) The wiring must be performed by a Licensed Electrical Contractor who files an ESA notification and provides the Certificate of Acceptance for your records.

How permits fit into your Aurora renovation budget and timeline

Keeping fixtures in their existing locations means zero municipal permit fees and no review wait before demolition day. Relocating drains or adding a basement bathroom adds scaled PDF drawing preparation, the Town’s permit fee, the electronic review window before start, and the on-site rough plumbing inspection. When a layout change—such as removing a bulky corner whirlpool deck in a builder-grade ensuite upgrade—makes your bathroom far more functional every morning, we build the permit steps right into our 5-step renovation process.
