Swimming pool fence permits

Whether the fence is new or existing, a permit is required before the swimming pool can be installed.

From London’s own page, checked Oct 2026.

The municipality lists what to submit. CodeEase shows what the building code asks of it. See CodeEase →

  1. Check whether you need a permit

    • Whether the fence is new or existing, a permit is required before the swimming pool can be installed.
    • The Swimming Pool Fence and Swimming Pool Regulation By-law PS-5 regulates the construction of the pool fence and stipulates when a permit is required.
    • A permit and fence are required if has a depth of more than 75 centimetres (≈ 2 ft 5½ in) at any point; and has a surface area of more than 1 square metre (≈ 10.8 sq ft).
    • Where a fitted and secured lid is provided while the unit is not in use, it is not a pool.
    • A gate is not mandatory; however, the swimming pool must be completely enclosed with a fence.
    • Any gate associated with a swimming pool fence or other form of access to the enclosed swimming pool must be self-closing and self-latching.
    • No, a swimming pool fence permit is not required provided a permit was previously approved.
    • Compliance with the setbacks will be required along with a drainage plan. This information can be emailed to zoning@london.ca.
  2. Only if you make changes to an existing fence

    Changing or rebuilding an existing fence

    Older homes and existing pools

    • Make sure any pool and its requisite fence has a current permit and has been inspected.
    • It is your responsibility to ensure compliance.
    • If you make changes to an existing fence, you may require a new permit.

    Do I need a permit to rebuild the fence?

    • If the entire pool fence is being replaced, it must meet current standards, and a Swimming Pool Fence Permit is required before work begins.
    • If a section is being replaced and there is a valid permit on file, a new permit is not required, provided the replaced section complies with the Swimming Pool Fence and Swimming Pool Regulation By-law - PS-5 and Fence By-law - PS-6.
  3. Plan the pool and the fence

    Review the Swimming Pool Fence and Swimming Pool Regulation By-law PS-5 and Fence By-law PS-6 before applying for your permit.

    • Section 4.25 of the Zoning By-law regulates where a pool and associated equipment may be located on your property, and provides guidance for you and your contractor regarding how to plan the pool itself.
    • Always consider the planning of the pool and the necessary fencing at the same time.
    • Don't forget diving boards, change rooms, cabanas, decks, pumps, and filters as part of your permit application. Always include those details when planning your new pool and applying for your pool fence permit as their locations are regulated by the Zoning By-law as well.
    • The Fence By-law PS-6 regulates non-pool fences and pool fences that exceed the minimum requirements of Swimming Pool Fence By-law PS-5.
    • The inside wall of your pool must be at least 1.5 metres (≈ 4 ft 11 in) from any property line and not closer to the street than the required setback. See section 4.25 (Swimming Pools) of the Zoning By-law Z.-1.
    • Typical acceptable materials include chain-link, solid wood boards, wrought iron, or other designs approved by the City. All pool fences must be of sturdy construction, capable of preventing unauthorized entry, and must meet all other requirements of the by-law.
    • No, a hedge does not satisfy the requirements for a compliant pool fence or enclosure.
    • A deck is permitted around a pool as an accessory structure, provided it complies with Section 4.1 (Accessory Uses) of the Zoning By-law. The presence of a deck does not remove the requirement for a compliant pool enclosure under the Swimming Pool Fence and Swimming Pool Regulations By-law - PS-5.
    • A shed or deck may require a separate permit depending on the size or height. Please contact the Building Division at 519-661-4555.
    • The owner of the pool/property is responsible for erecting and maintaining the fence so that it remains compliant with the by-law.
    • The Swimming Pool Fence and Swimming Pool Regulations By-law - PS-5 itself doesn’t mandate a neighbour’s permission. It regulates safety and enclosure standards. If the fence is entirely on your property, you don't need the neighbour’s permission. If you plan a shared/boundary fence, the neighbour’s permission may be needed — but that's a separate private matter, not governed by PS-5.
  4. Only if you are in a new subdivision

    Check whether your subdivision has been assumed

    New homes and subdivisions

    • For new subdivision, always check to make sure your subdivision has been assumed by the City of London before constructing a pool.
    • Newer neighbourhoods make use of swales and catch basins to direct water away from the property, and constructing a pool without considering overland flows, or consulting your lot grading plan, may prove very costly.
    • Premature installation, or changing the way water flows across your lot, may require costly re-engineering of your, and neighbouring properties, or could even lead to the removal of the pool at your expense.

    • Before filling the pool, please notify the City at pfinspection@london.ca.
    • Temporary fencing can stay in place for up to 120 days for new pools, or 30 days for existing ones, unless the City grants an extension.
