Every construction or demolition project in Calgary that lies within 2 meters of a public sidewalk, roadway, or other public way, is legally mandated to safeguard the public with robust barriers at least 1.8 meters high, as dictated by the National Building Code (NBC) Section 8.2.1.3. Cranes, excavators, falling debris, or incomplete structures pose risks not just to workers, but to anyone nearby. It is not just prudent-it is the law-to keep unauthorized persons away from potential harm while complying with established standards. For homeowners about to embark on a renovation, builders overseeing new developments, and developers with large-scale projects, understanding how to legally and effectively secure your site is crucial.

This guide examines the NBC 8.2.1.3 requirements, digs into City of Calgary mandates, and provides a practical commentary on how to get fencing, boarding, and barricades right from start to finish. Whether you are replacing an old garage, breaking ground on an infill, or demolishing a large commercial building, these principles are universal.

Understanding NBC 8.2.1.3: The Backbone of Site Security

The National Building Code of Canada (NBC) sets minimum standards for the design and construction of buildings to protect public health and safety. Specific to construction and demolition safety, NBC Section 8.2.1.3 stipulates the must-haves for fencing, boarding, or barricades when a project creates hazards for the public. While the complete NBC is hundreds of pages long, Section 8.2.1.3 is direct in its intent and application-a reflection of the high stakes involved.

Key Provisions of NBC 8.2.1.3

  • Mandatory Barriers: Unless construction/demolition takes place more than 2 metres away from any public way, barriers meeting NBC guidelines are required to keep the public safe. The protection must form a continuous shield between the hazard and the public, or on every open side of the site.
  • Minimum Height: Fencing, boarding, or barricade cannot be less than 1.8 metres (about 6 feet) in height. This is to resist climbing and keep errant debris from flying into public areas.
  • Smooth Surfaces: Barricades facing the public must have a finished surface, free of splinters or obstruction that could cause injury or snags.
  • Controlled Access: Any opening in the fencing for site entry must be equipped with robust, lockable gates that remain shut and locked when the site is unattended. These must stay in place until work is completely wrapped up.

These requirements are not arbitrary: they are designed to stop children, curious passersby, or vandals from entering sites where hazards may not be obvious, or where unpredictable events (like wind or machinery operation) could turn an innocuous situation into a dangerous one in seconds.

How the City of Calgary Enforces NBC Fencing and Barricade Rules

The City of Calgary is explicit in its application of the NBC requirements to every construction and demolition project within city limits. Both residential and commercial job sites are inspected for compliance, and enforcement action can be swift if the proper precautions are not observed.

City Requirements at a Glance

  • Construction Site Fencing: Every site is to be closed off with fencing or barricades before any dangerous work begins-particularly excavations, demolition, or projects where ground disturbance exposes open hazards.
  • Ongoing Maintenance: Fencing, boarding, or barricades must remain in pristine condition for the entire project. Damage, openings, or missing sections are not tolerated and can trigger citations, stop-work orders, or fines.
  • Public Protection Site Safety Plan (PPSSP): For towers, residential complexes, or any building five stories or taller, a comprehensive PPSSP is a must. This document details not only fencing/barricade strategy, but how the public will be safeguarded against overhead work, crane lifts, debris, and site traffic.

If your project involves excavating a new basement, building a detached garage, or carrying out full-scale demolition, these requirements apply to you. Failure to comply does more than expose the public to danger-it can halt your project via legal channels.

Types of Barriers: Fencing, Boarding, and Barricades

Choosing the right solution for your site is as much a practical concern as it is a regulatory one. Not every fence or barricade is built the same. The context-location, type of work, proximity to foot/vehicle traffic, duration, and weather exposure-all inform what will keep your site secure and the public protected.

1. Fencing

  • Chain Link Fence: The most common fencing material for construction sites in Calgary. Meets NBC height requirements, resists weather, and can be easily fitted with privacy mesh to control dust and visual distractions. Temporary fence panels are anchored in place and linked with clamps or brackets.
  • Steel Mesh Panels: Portable, quick to erect, and often used for short-duration projects or those where security from theft/vandalism is an elevated concern. Can be driven into soft ground or attached to concrete blocks for stability.

2. Boarding

  • Plywood Hoarding: A solid plywood wall, often painted or finished for aesthetics, creating a seamless barrier. Boarding is especially suited to infill developments in dense urban neighborhoods where aesthetics, dust control, and enhanced security are crucial.
  • Timber Framing and Sheet Goods: Wood frames clad in OSB or plywood (minimum 12mm thickness is a practical standard) offer durability and can absorb moderate impacts. Carefully built hoarding often features pedestrian protection (overhead) for high-traffic areas.

3. Barricades

  • Concrete Jersey Barriers: For sites proximate to vehicular traffic, heavy precast concrete barriers are used to prevent errant vehicles from entering the site, and to provide a stout visual cue of “no access.” These are often paired with fencing above for extra height.
  • Water-Filled Plastic Barriers: Portable for temporary use, these can rapidly be set in place and filled to provide mass against impact. They can be visually striking and useful for sidewalk diversions, though long-term exposure to Calgary UV and temperature swings may degrade the plastic.

In choosing among these types, cost, duration, security, and city regulations must all be weighed. No matter what style, NBC 8.2.1.3 demands a minimum height, a smooth public-facing surface, limited and controlled access points, and regular maintenance.

Who is Responsible for Site Fencing and Barricades?

The onus for compliance with NBC 8.2.1.3 and Calgary’s adaptations falls on the prime constructor, who may be a general contractor, demolition contractor, or an owner acting as their own builder. In smaller or residential projects, homeowners themselves may be responsible-but only if they have clearly assumed the role of the prime contractor and secured all relevant permits. Ignorance of code is not a legal defense in the event of an incident.

Builders and developers must ensure that every subcontractor understands and abides by these requirements. If you are the property owner but have hired a demolition company or general contractor, the contract should stipulate who is providing safety fencing, the type used, and the standards of regular inspection and maintenance. At Kingsway, for example, temporary fencing is included in most proposals, including ongoing inspection and replacement as necessary for the life of the project.

Calgary’s Permit Requirements for Fencing, Boarding, or Barricading

Depending on project scale, duration, and location, Calgary requires a mix of permits to be in place prior to mobilizing fencing or barricading on site.

1. Development Permit

A Development Permit is necessary whenever a project will substantially alter land use, such as redeveloping a residential lot, building an addition, or pursuing setback or site coverage relaxations. Fencing, when temporary and solely for safety, does not typically trigger a Development Permit-unless it becomes a de facto permanent installation or alters sidewalk/road access over an extended period. For projects situated in high-traffic urban cores or involving hundreds of feet of hoarding, the City may require a relaxation and associated permit.

  • Estimated Processing Time: 10 to 12 weeks
  • Fees: Determined by project type but may include review fees for barricading/hoarding that affects City rights-of-way.

2. Building Permit

Any construction, alteration, or demolition of a building project in Calgary requires a Building Permit. This is separate from the Development Permit and is focused on ensuring the technical safety and code compliance of what is built (or removed). In the case of retaining walls, for example, or demolition that leaves pits or excavations exposed, a Building Permit will stipulate the minimum expectations for site protection, including fencing/barricades.

  • Estimated Processing Time: 7 days (residential); longer for commercial/complex projects
  • Fees: For a retaining wall or similar work, expect ~$202 plus a 4% Safety Codes Council levy, totaling approximately $210.08. Fees for larger-scale boardings/hoardings may vary, especially where City infrastructure is impacted.

3. Encroachment and Obstruction Permits

If your fencing, boarding, or barricade extends onto City of Calgary property (such as a sidewalk, road, lane, or public park), you must apply for an encroachment or temporary obstruction permit. This includes construction hoarding that narrows a sidewalk or requires pedestrian detours. Failure to secure this permit can lead to removal orders, fines, or even civil liability in the event of public injury.

Public Protection Site Safety Plan (PPSSP) and High-Rise Construction

Not all projects require a formal PPSSP, but for buildings five storeys or higher (or any structure classified as a “high building” under Article 3.2.6 of the Alberta Building Code), the law mandates a comprehensive plan filed with the City prior to issuance of construction permits. This plan goes beyond standard fencing-requiring detailed drawings, risk assessments, schedules for inspection, debris netting strategies, crane zones, and clear methods for public communication.

  • Content: Must address fencing/barricading, signage, emergency access, overhead protection, and debris containment.
  • Qualified Personnel: Plans should be prepared or reviewed by a competent health and safety professional or engineer.

If your project is anywhere near this scale, engage a demolition/excavation partner with deep PPSSP experience and a track record with the City. For most residential and low-rise work, adherence to NBC 8.2.1.3 with solid barricades and diligent maintenance is sufficient.

Choosing Fencing and Barricade Materials for Calgary Conditions

Calgary’s climate is nothing if not challenging. Sudden wind gusts, ice, spring thaw, dust storms, and variable UV exposure all break down lesser fence and barricade materials. The code does not specify the exact materials to use, but “a robust fence, boarding, or barricade” is the expectation. Here’s how to build a barrier that meets both NBC and practical needs:

1. Durability and Strength

  • Steel Chain Link Panels: Galvanized for rust resistance; ideally with welded joints, stable feet/blocks, and locking clamps to prevent toppling. If site will be exposed to frequent strong winds, tie-downs or anchoring are critical.
  • Plywood/Timber Hoarding: Minimum 12mm plywood (painted/sealed) on pressure-treated framing. Untreated wood can wick water and splinter, creating safety and appearance problems. Use durable fasteners and inspect after storms for integrity.
  • Concrete/Plastic Barriers: Ensure units are rated for impact and interlock for stability. Do not rely on light plastic barriers in traffic-exposed areas without water-filling or additional anchoring.

2. Weather Resilience

  • Rust Protection: All ferrous metals (fencing, bolts, clamps) should be hot-dip galvanized or otherwise rust-protected.
  • UV Resistance: For mesh sheeting or plastic barrier components, only use UV-stabilized materials to avoid embrittlement and failure mid-project.
  • Snow and Ice: Leave enough clearance at the base of fencing to accommodate snow drift but prevent lift-up. Avoid creating trip hazards or restricting water drainage from the site.

3. Security

  • Anti-Climb Features: Mesh privacy fabric (or board hoarding) reduces climbing potential. Never use step stones or waste bins near perimeter fencing.
  • Gate Hardware: Must be robust, lockable, and resistant to tampering. Padlocks should be shielded from bolt cutters.

Maintaining Your Fencing, Boarding, and Barricades

Putting barriers up is only half the job-ongoing maintenance is mandated both by NBC 8.2.1.3 and the City of Calgary. A barrier that is damaged, missing, or left open is a code violation and a liability risk.

Best Practices for Maintenance

  • Daily Inspections: Walk the perimeter each day to check for wind damage, vandalism, missing panels, loose bolts, snow drifts, or gateways left unlatched.
  • Weather Response: Following storms or strong winds, increase inspection frequency. Have extra fence panels/hoarding materials on-hand for immediate repair.
  • Debris Management: Prevent fence lines from becoming garbage traps or windrows of construction waste.
  • Prompt Gate Repairs: If gates are damaged or fail to lock, halt work until secure access is restored.

Documentation: Keep detailed records of inspections, repairs, and incidents, as these may be requested during a City inspection or in the event of an incident investigation.

Signage: Communication with the Public

Every barricaded construction or demolition site should clearly post contact information for the general contractor or site responsible party. This is as much about public reassurance as about rapid response to issues or emergencies-including trespassing, property damage, or urgent site repairs. Common best practices include:

  • Posting at least one weather-resistant sign at each public-facing fence segment or gate
  • Including both a site phone and email, plus after-hours emergency line
  • Displaying regulatory notices required by the City (permits, site plans, etc.)
  • Marking any special hazards-such as “DO NOT ENTER: ASBESTOS ABATEMENT” for demolitions involving hazardous materials

Well-maintained signage is a vital part of a well-run site. It reduces neighbor complaints and demonstrates diligence in your approach to public safety.

Common Hazards Fencing, Boarding, and Barricades Help Prevent

Beyond protecting against physical intrusion, robust fencing and barricades guard the public against:

  • Falling objects: Tools, building materials, and demolition debris can shift unexpectedly.
  • Trips and falls: Open excavations, uneven ground, and construction rubble are hidden dangers to the uninitiated.
  • Machinery movement: Even slow-moving excavators pose deadly risks to unaware pedestrians or drivers.
  • Unauthorized entry: Curious children, trespassers, or vandals face real peril, and property owners face potential legal claims if the site is unfenced.
  • Noise and dust mitigation: Solid hoarding can also reduce dust spread and provide some acoustic buffering for neighbors.

Ultimately, the public’s safety is more than a code requirement-it’s a duty of care. Barriers buy you time and control over who is near work in progress and limit the domino effects if something unexpected happens.

Real-World Examples: Fencing and Barricading Approaches in Calgary

Seeing standard best practices in operation in local conditions offers valuable insight. Consider these typical project scenarios:

Residential Infill Demolition

  • Site is within two meters of both a public sidewalk and neighboring home. Temporary chain-link panels (1.8 meters), with lockable gates front and back, are installed. Snow fencing blocks debris and privacy tarp is attached for neighbor comfort.
  • Gates are kept locked on weekends, with after-hours contacts posted on signage. Repairs are made immediately after a late-winter windstorm blows down two panels.

Commercial Strip-Mall Excavation

  • Site abuts a city bus stop and is alongside busy traffic. Concrete Jersey barriers are placed at curbside, topped with steel mesh fencing. Hoarding is painted white to resist glare and features custom graphics for commercial branding.
  • Public sidewalk is re-routed safely behind barriers, with clear directional signage. City permit for sidewalk obstruction is prominently posted.

High-Rise Condominium Development

  • Beyond standard fencing, a full public protection plan is submitted, including overhead protection for street-level pedestrians, debris netting, enhanced access control, and nightly security patrols. Fencing is repaired immediately after winter freeze-thaw causes heaving.
  • Neighbours are kept informed about construction timelines and site contacts, reducing complaints and ensuring cooperation.

Consequences of Non-Compliance: Why NBC 8.2.1.3 Should Never Be Ignored

The consequences of disregarding NBC 8.2.1.3 or the City of Calgary’s requirements are severe, both in human and financial terms. Fines for failing to secure a demolition or construction site can reach thousands of dollars per day of infraction. If a member of the public is injured due to inadequate fencing or barricades, liability may extend beyond insurance coverage, especially if willful neglect can be shown. Even a single unauthorized entry or minor injury can trigger:

  • Project shutdowns pending corrective measures
  • Legal claims/lawsuits by injured parties or adjacent property owners
  • Insurance premium increases or policy non-renewals
  • Citation and loss of building or development licenses

Ultimately, proper barricading is not a box to check-it is a foundation of due diligence, protecting lives and investments alike.

Timeline and Process: Getting Fencing and Barricades Right From Day One

To ensure smooth, uninterrupted progress-and avoid compliance headaches-follow this project lifecycle for fencing/barricading:

  1. Planning:
    • Identify every public way within 10 meters of the site. Map all open boundaries.
    • Consult early with your demolition/excavation contractor about expected barrier types, permit requirements, and schedule.
    • Determine if a Public Protection Site Safety Plan is required.
  2. Permitting:
    • Apply for necessary development and building permits. For any encroachment onto public space, secure temporary use/obstruction permits.
    • Submit site fencing/boarding drawings if required by the City.
  3. Installation:
    • Erect fencing or hoarding prior to heavy equipment mobilization. Do not rely on warning tape or barrels for anything but the briefest/smallest site activities.
    • Clearly define access points for trades, deliveries, and waste removal.
  4. Ongoing Management:
    • Perform daily inspections. Replace or repair damaged sections immediately.
    • Update signage and contact information as responsible parties change.
  5. Removal and Close-Out:
    • Only remove fencing/hoarding once hazards are eliminated (exposed pits filled, sharp debris cleared, hazardous materials abated/risk-locked).
    • Inspect for property damage to public infrastructure during de-installation.

Frequently Asked Questions: Fencing and Barricading in Calgary Construction

Do I need a fence for every construction or demolition project?

If your project is two meters or less from any public sidewalk, road, or lane-or if open sides present hazards to the public-the NBC requires fencing or comparable barriers. Smaller projects set deep inside private property may be exempt, but always consult the City for interpretation.

Can I use “snow fence” or orange mesh barriers in place of steel-panel fencing?

Orange snow fence or mesh netting does not meet the NBC 1.8m height and robustness standard for construction unless specifically allowed by the City for minor/short-duration projects. Permanent fencing, board hoarding, or interlocked panels are best practice.

Who inspects my fencing or barricades?

City of Calgary inspectors will check during any site safety or building inspection. They may also inspect after public complaints, or in the event of an incident. Insufficient fencing will result in orders to comply and may slow down your project.

Is there funding or assistance for required fencing/hoarding costs?

Costs are borne by the project owner unless explicitly stated in agreements with contractors. Some insurance policies require proof of fencing as a prerequisite for coverage. Build these costs into your initial budget-security is rarely an area for cost-cutting.

When can I take down my fencing/barricades?

Barriers should remain in place until all hazards are remediated-pits filled, demolition debris cleared, and the public cannot enter unsafe areas. Remove fencing after post-project inspection whenever feasible.

Best Practices Summary-Staying Safe, Legal, and On Time

  • Plan fencing/barricading strategy before permits are submitted or work begins
  • Choose durable materials that stand up to Calgary’s unique climate and potential site hazards
  • Inspect and maintain fencing daily; repair promptly after damage
  • Post clear signage with 24/7 site contacts and relevant regulatory information
  • Work with experienced demolition/excavation contractors familiar with Calgary regulations and best practices
  • Document inspections and corrective actions to protect yourself in the event of disputes or incidents
  • Leave no ambiguity-if in doubt, over-protect rather than under-protect

Why Quality Barriers Are an Investment, Not a Cost

Beyond legal compliance and public safety, good fencing and barricading send a strong signal to neighbors, regulators, and potential clients about the professionalism of your project. Sloppy barriers, ad hoc repairs, or unsightly hoarding create neighborly friction and make you more likely to face targeted inspections or public complaints.

Well-executed barriers help reduce theft and vandalism, lower insurance premiums, and minimize disruptions. For properties being redeveloped for sale, presentation-even in a demolition or excavation phase-affects perception, long after the old foundation is dust.
