Calgary fence bylaws explained simply: legal heights, when permits are needed, property line etiquette, and shared-fence costs.

Few home projects generate neighbour disputes faster than a fence built on bad assumptions. The good news: Calgary's fence rules are straightforward once someone explains them plainly. Here they are.

## How Tall Can My Fence Be?

The City of Calgary Land Use Bylaw sets simple maximums:

- **Front yard:** up to **1.5 m (about 5 ft)**
- **Side and rear yards:** up to **2 m (6.5 ft)**

Corner lots have extra restrictions where fences meet streets — sight lines for drivers must be preserved near intersections. If your lot backs onto a busy road, you may also want an acoustic fence, which has its own design considerations.

## Do I Need a Permit?

For a standard fence at standard heights: **no permit required.** You only need permits if:

- You want to exceed the height maximums (requiring a development permit approval)
- Your property has specific land use designation constraints
- Retaining walls are involved above certain heights

We confirm requirements for your specific lot during the estimate — it takes minutes and prevents months of headache.

## Whose Fence Is It? Property Lines 101

Before any post goes into the ground, know where your property line actually is. Key points:

1. **Your real property report (RPR)** shows lot lines. If you don't have one, your municipality or a surveyor can help.
2. **Assuming the old fence was right** is how fences end up on neighbour land. Old fences migrate.
3. **Fences on the line are shared property** under Alberta law — neighbours generally share maintenance responsibility and should agree before removal or replacement.

A five-minute conversation with your neighbour before construction prevents ninety percent of fence disputes. Bring cookies. Seriously.

## Materials That Survive Calgary Winters

Calgary's chinooks — those wild temperature swings from -25°C to +10°C in a day — are brutal on fences. Freeze-thaw cycles heave posts that aren't set below frost line in concrete. Our standards:

- Posts set **below frost depth**, anchored in concrete
- Rot protection at grade level (rot boards or pressure-rated lumber)
- Hardware rated for exterior use — not whatever was cheapest

## Repair or Replace?

A leaning section usually means failed posts, not a failed fence. Replacing two posts can buy years of life for hundreds of dollars instead of thousands. We'll always tell you honestly which situation you're in — repair-first advice is kind of our thing.

## Ready for a New Fence?
