Fence Permit in Cambridge, Ontario: What You Need to Know

If you're planning to install a fence in Cambridge, Ontario, you probably want to know if you need a permit and how to get one. The rules vary depending on your fence's height, location, and whether it's near a corner lot or public right-of-way.

Here's what Cambridge homeowners need to understand before building a fence.

When You Need a Fence Permit in Cambridge

Cambridge requires a fence permit in these situations:

• Any fence over 2.0 metres (6.6 feet) in height anywhere on your property
• Any fence in the front yard that exceeds specific height limits (typically 1.2 metres or 4 feet)
• Corner lot fences within the sight triangle area (more on this below)
• Fences within 0.9 metres (3 feet) of a municipal sidewalk or public right-of-way
• Swimming pool enclosures (must meet Ontario Building Code barrier requirements)

You generally don't need a permit for:

• Rear or side yard fences up to 2.0 metres (6.6 feet) tall
• Decorative garden fencing under 1.2 metres (4 feet) anywhere on the property
• Temporary construction fencing

Even if you don't need a permit, you still must follow Cambridge's fence bylaws regarding height, setbacks, and materials.

Cambridge Fence Height Limits

Cambridge enforces different height limits based on where the fence sits on your property:

| Location | Maximum Height | Notes |

|--------------|-------------------|-----------|

| Rear yard | 2.0 m (6.6 ft) | No permit needed if under this height |

| Side yard | 2.0 m (6.6 ft) | No permit needed if under this height |

| Front yard | 1.2 m (4 ft) | Permit typically required; check your specific zoning |

| Corner lot sight triangle | 0.9 m (3 ft) | Strictly enforced for traffic safety |

Corner lot sight triangle refers to the triangular area at street intersections where fences must be kept low to maintain driver visibility. This typically extends 4.5 metres (15 feet) from the corner in both directions.

If you want a taller fence than these limits allow, you'll need to apply for a minor variance through Cambridge's Committee of Adjustment—a process that costs extra and takes longer.

Fence Setback Requirements

Cambridge requires fences to be set back from property lines and municipal infrastructure:

• Property line: Generally, you can build on your property line, but you must stay on your side. If you're sharing costs with a neighbor, document this in writing.
• Municipal sidewalk: Fences must be at least 0.9 metres (3 feet) back from city sidewalks.
• Street line/right-of-way: Check your survey—you may not own all the way to the curb. Fences in the municipal right-of-way require a permit and may be rejected.
• Easements: You cannot build fences over utility easements, drainage easements, or other registered easements without permission from the easement holder.

Before digging fence posts, call Ontario One Call (811) to mark underground utilities. This is free and legally required. Hitting a gas line or fiber optic cable can cost you thousands in repairs and fines.

For deck projects requiring utility marking, see our guide on Ontario One Call before deck footings.

How to Apply for a Fence Permit in Cambridge

The application process is straightforward if you have the right documents ready.

What You'll Need

1. Completed fence permit application form (available on Cambridge's website or at City Hall)

2. Site plan showing:

- Property boundaries and dimensions

- Proposed fence location and height

- Distance from property lines, sidewalks, and streets

- Location of existing structures (house, garage, shed)

- Corner lot sight triangles if applicable

3. Proof of property ownership (recent tax bill or property deed)

4. Swimming pool barrier details if the fence encloses a pool (must meet OBC requirements)

Application Steps

1. Prepare your site plan: You can sketch this yourself on graph paper or print a copy of your survey and mark up the fence location. Include measurements.

2. Fill out the application: Download the form from Cambridge's building permits page or pick one up at City Hall (50 Dickson Street, Cambridge).

3. Submit and pay: You can submit in person or by mail. Payment is due at submission.

4. Wait for review: Cambridge typically reviews fence permit applications within 2-5 business days for straightforward cases. Complex applications or those requiring variances take longer.

5. Receive approval: Once approved, you'll get your permit. Post it visibly at the site during construction.

6. Build your fence: Install the fence according to your approved plans.

7. Inspection: Cambridge may inspect the fence after installation, especially for pool barriers or fences near municipal infrastructure.

A typical 150-foot privacy fence runs $5,250-8,250 installed, depending on material and site conditions.

Common Fence Permit Mistakes in Cambridge

Avoid these issues that delay permits or trigger bylaw complaints:

Building Without a Permit

Even if you think your fence doesn't need a permit, double-check. Cambridge enforces fence bylaws, and neighbors do report violations. If you're caught, you may have to:

• Apply for a retroactive permit (if possible)
• Pay fines
• Remove or modify the fence to meet bylaws
• Defend against neighbor complaints

Ignoring Corner Lot Sight Triangles

This is the most common reason for fence permit rejections on corner lots. Cambridge takes traffic safety seriously. If your fence blocks driver sightlines, you'll be required to lower it or move it back.

Assuming You Own to the Sidewalk

Many homeowners assume their property extends to the sidewalk or curb. In reality, there's often a municipal right-of-way that you don't own. Check your survey before staking out fence posts.

Not Talking to Your Neighbor

Ontario's *Line Fences Act* and common courtesy both suggest discussing your fence plans with neighbors before building. If the fence sits on or near the property line, clarify:

• Exact location of the property line (hire a surveyor if there's any doubt)
• Who pays for what
• Fence design and height
• Maintenance responsibilities

A simple conversation prevents disputes. Written agreements are even better.

Forgetting Pool Barrier Requirements

If your fence encloses a swimming pool, it must meet Ontario Building Code barrier requirements:

• Minimum height of 1.2 metres (4 feet)
• No climbable features (horizontal rails, nearby structures)
• Self-closing, self-latching gates with latches at least 1.5 metres above grade
• No gaps larger than 100 mm (4 inches)

Pool barrier inspections are mandatory and strictly enforced. For similar structural requirements on decks, see our guide on deck railing height in Ontario.

Fence Materials and Cambridge Bylaws

Cambridge's fence bylaw regulates materials to some extent, particularly regarding appearance and maintenance.

Allowed Materials

• Wood (pressure-treated, cedar, pine)
• Vinyl/PVC
• Aluminum
• Chain-link (residential areas—check zoning; some neighborhoods restrict chain-link to rear yards only)
• Composite materials
• Wrought iron or ornamental metal

Restricted or Prohibited Materials

• Barbed wire or razor wire (residential areas—agricultural properties may have exceptions)
• Electrified fences (not permitted in residential zones)
• Rusted, deteriorated, or unsafe materials
• Tarps, pallets, or other improvised materials (these violate property standards bylaws)

Cambridge expects fences to be maintained in good repair. If your fence becomes structurally unsafe or unsightly, the city can order repairs or removal.

What Happens If You Don't Get a Permit

If Cambridge discovers an unpermitted fence that requires a permit, you'll receive a notice to:

1. Stop work immediately

2. Apply for a permit (retroactive permits are sometimes allowed)

3. Pay fines (typically $300-500 for first offenses)

4. Modify or remove the fence if it doesn't comply with bylaws

Repeat violations or refusal to comply can result in:

• Higher fines
• Court orders
• City-ordered removal at your expense
• Liens against your property

Neighbors can also file complaints if your fence violates bylaws or encroaches on their property.

Fence Permits vs. Deck Permits in Cambridge

If you're building both a fence and a deck, you'll need separate permits for each. Cambridge's deck permit requirements are more complex than fence permits and include structural drawings, foundation details, and inspections.

Key differences:

| Fence Permit | Deck Permit |

|------------------|-----------------|

| Simpler application | Requires detailed drawings |

| 2-5 day review | 10-20 business day review |

| $100-150 fee | $200-400+ fee depending on size |

| Single inspection (if any) | Multiple inspections (footing, framing, final) |

For full deck permit details, see our guide on Cambridge deck permit applications.

Shared Fences and Neighbor Disputes

Ontario's *Line Fences Act* governs disputes between neighbors over shared fences, but it primarily applies to agricultural and rural properties. In urban Cambridge, disputes are usually handled through:

• Negotiation: Talk to your neighbor first
• Mediation: Cambridge offers dispute resolution services
• Fence viewing: A neutral third party inspects and makes recommendations (rarely used)
• Small claims court: For property line disputes or damage claims

Best practice: Get a professional survey if there's any doubt about the property line. A $600 survey beats a $5,000 legal dispute.

If you're replacing an old shared fence, offer to split costs with your neighbor. If they refuse, you can build entirely on your side of the property line at your own expense.

Common Questions

Do I need a permit to replace an existing fence in Cambridge?

If the existing fence is legally compliant (correct height, setback, location), you generally don't need a new permit to replace it with a similar fence in the same location. However, if you're changing the height, moving the fence, or the old fence was built without a permit, you may need to apply.

When in doubt, call Cambridge Building Services at 519-740-4680 ext. 4330 to confirm.

How long does a fence permit last in Cambridge?

Cambridge fence permits are typically valid for 6 months from the date of issue. If you don't complete the fence within that time, you may need to renew the permit or reapply.

Can I build a fence higher than 2 metres in Cambridge?

Yes, but you'll need to apply for a minor variance through the Committee of Adjustment. This process costs $1,500-2,500, requires public notice to neighbors, and takes 4-8 weeks. Approval is not guaranteed—you'll need to demonstrate that the taller fence won't negatively impact neighbors or the streetscape.

Do I need a permit for a gate in Cambridge?

Gates are considered part of the fence structure. If the fence requires a permit, the gate is included. Pool barrier gates have specific requirements (self-closing, self-latching) that will be reviewed as part of the permit.

What if my neighbor builds a fence on my property?

If a neighbor's fence encroaches on your property, you have a few options:

1. Talk to the neighbor: They may not realize the fence is over the line

2. Get a survey: Professional confirmation of the property line is essential

3. Request removal: If they refuse, send a formal letter (keep a copy)

4. Legal action: Small claims court or civil court for trespass and removal

Act quickly—if you wait years without objecting, you may lose your right to demand removal (adverse possession or prescriptive easement claims).
