Does Langley require a permit to replace a gas boiler?
Yes, from Technical Safety BC. The Township of Langley's Other Building Permits page states directly: "For gas and electrical permits, refer to Technical Safety BC." Technical Safety BC's jurisdiction page confirms that Langley is not among the municipalities delegated to issue gas permits, so the boiler replacement is permitted provincially.
The Township's permits cover the work around the appliance. Its Plumbing and Sprinklers applications cover fire-protection sprinklers, irrigation sprinklers, plumbing fixtures and devices, and re-piping a dwelling or apartment, and the Township notes that when a building permit exists, plumbing is typically included on it. Residential building permits cover new single-family dwellings, additions and alterations, two-dwelling houses, row houses, accessory buildings and secondary suites.
Who pulls the permits
The licensed contractor applies for the Technical Safety BC gas permit; the homeowner or contractor applies for the Township permits the scope requires. Technical Safety BC's homeowner gas permit route is limited to qualifying single-family owners, and strata and duplex owners must use a licensed contractor.
Langley's permit applications are digital — the Township says paper applications are no longer accepted where digital submission is available — and plumbing work such as replacing water lines, adding a backflow preventer, grease interceptor installation or water treatment can be part of the permit file. For a boiler replacement, the contractor confirms which Township stream the scope touches.
What the inspection involves
The Township's building and plumbing permits carry the inspection stages for the work they cover. The gas side is inspected under the provincial permit: the gas fitter files the notification of completion and at least one inspection is requested within 180 days of permit issuance, with Technical Safety BC determining whether a physical assessment is needed.
The gas inspection verifies the gas piping, connections, appliance installation and venting against the code, and the Township inspections verify the plumbing or construction scope. The passed records from both streams belong with the appliance documents at handover.
The replacement project, step by step
A Langley replacement starts with an assessment of the existing boiler, its venting, gas supply and the hydronic system, and a heat-loss calculation for the required output. The equipment and hot-water strategy are chosen next — condensing heating-only with an indirect tank, or a combi — then the permits are confirmed for the property.
Installation covers the appliance, venting, condensate, gas and water connections, and commissioning with combustion readings. The inspections follow, and the handover files the permit records with the commissioning report and warranty registration. On the Township's larger lots and acreage properties, gas line routing and vent terminal placement are worth settling during the assessment.
- Assessment and heat-loss sizing
- Technical Safety BC gas permit for the appliance work
- Township plumbing or building permit where the scope requires
- Installation, venting, condensate and commissioning
- Inspections and records handover
What ROMA handles on a Langley replacement
ROMA Heating & Cooling is a Technical Safety BC licensed gas contractor and lists Langley among its service areas, with a Langley page covering boiler installation, maintenance, troubleshooting, replacement and tune-ups. On a replacement, ROMA handles the assessment, the sizing, the permit applications, the installation, the commissioning and the inspection coordination.
The replacement, installation and commissioning services on this site describe the project scope, and the consultation service is where equipment and hot-water strategy are settled. The Langley city page links the services available in the city.
Langley housing stock and boiler considerations
Langley spans the City and the Township, with housing that runs from established detached homes and townhouses to newer subdivisions and acreage properties. Older homes often have conventional boilers and baseboards; newer builds more often use condensing boilers, combis or in-floor radiant loops, and larger houses frequently have several heating zones.
On acreage and rural properties, propane can appear alongside natural gas, which matters because Technical Safety BC keeps jurisdiction over propane in all BC municipalities. The assessment identifies the fuel, the system type and the venting options before equipment is chosen.
