Does Chilliwack require a permit to replace a gas boiler?
The gas permit comes from Technical Safety BC. Chilliwack's building-permit pages list no gas or heating-system permit category, and the City's building permit program covers construction work and related trades, so installing or replacing the gas appliance is permitted provincially. Technical Safety BC's jurisdiction page confirms that Chilliwack is not a delegated gas municipality.
The City's own permits still matter to construction scope. Chilliwack requires a building permit for most construction work, accepts online applications through its MyCity portal, and publishes application checklists and a Building Regulation Bylaw that administers the Building Code locally. Plumbing work under the City's process includes a plumbing contractor certification (TQ) form, which is part of the documentation the City asks for.
Who pulls the permits
The licensed contractor applies for the Technical Safety BC gas permit. 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 — a common situation in Chilliwack's growing multi-unit stock.
City permits are applied for through the MyCity portal by the contractor or owner depending on the scope. Technical Safety BC's homeowner page asks owners to confirm a permit is in place before work begins, and that check covers both the provincial gas permit and any City permit the project holds.
What the inspection involves
Chilliwack schedules building inspections through its online eInspections system or by phone, and general building inspection requests must be received before 3:30 p.m. at least one business day before the inspection is needed. The city asks for the street address, permit or folder number, and the type of inspection being requested. Those inspections apply to the City permits the project holds.
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 piping, connections, appliance installation and venting against the code.
The replacement project, step by step
A Chilliwack replacement starts with an assessment of the existing boiler, its venting, gas supply and hydronic system, and a heat-loss calculation for the required output. The equipment and hot-water strategy are chosen next, then the permit path is confirmed: the Technical Safety BC gas permit for the appliance, and any City building permit the scope requires.
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 Chilliwack's hillside homes, vent terminal clearances and condensate drainage are worth reviewing during the assessment.

What ROMA handles on a Chilliwack replacement
ROMA Heating & Cooling is a Technical Safety BC licensed gas contractor based in Burnaby and lists Chilliwack among its service areas, with sub-areas including Sardis, Promontory, Vedder Crossing, Yarrow and Rosedale. 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 Chilliwack city page links the services available in the city.
Chilliwack housing stock and boiler considerations
Chilliwack has grown quickly — the City estimates a population of 112,500 as of 2025, up about 11,700 residents since 2020 — and its housing reflects that: older homes in the downtown and Fairfield Island areas, newer hillside homes in Sardis and Promontory, and acreage properties in Yarrow and Rosedale.
Older homes often have conventional boilers feeding baseboards or radiators; newer homes more often use condensing boilers, combis or in-floor loops. Acreage properties can involve propane, which remains under Technical Safety BC jurisdiction in every municipality. The assessment establishes the fuel, the system type and the venting options before a model is chosen.
