Do I need a permit?
Decks and fences are common home improvements, but they are regulated to keep your family and neighbours safe. In Wrenford, a building permit is required for any covered deck, any sunroom, and any uncovered deck that is more than 60 centimetres (two feet) above the ground. A development permit is also required for all decks to ensure the location follows our zoning rules.
Fences do not require a building permit, but they must follow our Zoning By-law 2016-040 and the Traffic and Parking By-law 2014-075. If you are unsure about your specific property, contact the Planning Department at 519-555-0100 or [email protected] before you start.
Deck and sunroom permits
When you apply for a deck or sunroom, we review both the building standards and the zoning requirements. You will receive both permits once the application is approved. This process covers single-family homes, duplexes, and row houses. If your sunroom will be heated or insulated, you may need to apply for a renovation permit instead.
Regardless of the size or height, you must make sure your proposed structure does not cross over any easements on your property. You can check for easements by contacting Information Services Corporation of Ontario or by asking a professional surveyor. If you need help, our planning staff can point you in the right direction.
To apply, complete the Deck and Sunroom Permit Application Package and submit it through our online portal or in person at Wrenford City Hall. The application must be signed by the legal owner of the property. If your project includes gas or electrical work, you will need separate permits from Technical Safety Services Ontario.
Permit fees and timeline
Permit fees are due before the permit is issued. You can pay online, by phone, or at the service counter on the main floor of City Hall.
| Permit type | Fee |
|---|---|
| Deck (uncovered or covered) | $150.00 |
| Sunroom | $200.00 |
| Development permit (deck) | $75.00 |
Processing usually takes five to seven business days. Once approved, you will receive an email with the approved drawings and payment instructions. Do not start construction until you have the permit in hand. Work that begins before the permit is issued will result in a fine.
Inspections
A final inspection is required after the structure is fully built, including posts, beams, guards, and handrails. Covered decks may require additional inspections for the foundation and framing depending on the size of the project. The inspector will check that the build matches the approved drawings and meets the Ontario Building Code standards.
Property tax adjustments
Adding a deck or sunroom may increase the value of your property. This can lead to a small increase in your annual property tax bill. You can view the current tax rates on Property Tax. If you want a detailed estimate of how much your taxes might change, submit a service request through Wrenford 311.
Fence rules
You do not need a building permit to build a fence, but you must follow the height and placement rules in the Zoning By-law 2016-040. Fences near roads must also follow the Traffic and Parking By-law 2014-075 to ensure drivers have a clear view.
- Front yard: Up to 1.2 metres (four feet) high.
- Back or side yard: Up to 2.1 metres (seven feet) high, or 2.4 metres (eight feet) if next to an arterial road.
Check the classification of your nearest road to see which height limit applies. You can find a map on the Roads & Winter Maintenance page.
Maintenance and by-law compliance
Under the Property Standards By-law 2019-112, all decks, fences, porches, and stairs must be kept in good repair. This means they should not have significant damage, rot, peeling surfaces, or loose parts. If your structure is not maintained, By-law Enforcement can issue a notice. Repeated violations can result in fines between $100 and $300.
If you notice a neighbour's structure is unsafe or in disrepair, you can report it by calling Wrenford 311 or using the Wrenford 311 app. Please have the address and a description ready. All reports are confidential, but we cannot accept anonymous complaints.
Common questions
Do I need a permit for a pergola or gazebo?
Pergolas do not require a building permit as long as they are not attached to the house and cannot hold a snow load. Gazebos that are attached to your home or cover more than 25 square metres require a building permit. For zoning rules, see the Building Permits page.
Do I need a permit for a raised patio?
No. A patio that is supported directly on the ground or fill does not need a permit. General landscaping also does not require a permit.
Can a contractor fill out the application for me?
Anyone can fill out the paperwork, but the application must be signed by the legal owner of the property. While contractors are experienced, the homeowner is legally responsible for making sure the build meets all codes and by-laws. Our planning staff can answer general questions but cannot provide design services.
What if I just want to replace the boards or rails?
Replacing deck boards, handrails, or guards does not require a permit. However, if you are replacing structural members like posts or beams, or if you are changing the size or location of the deck, you will need a permit.
