Does Coquitlam require a permit to replace a gas boiler?
The gas permit comes from Technical Safety BC, not the city. Coquitlam's website routes electrical and gas permits to Technical Safety BC — the city's permit menu links directly to technicalsafetybc.ca — and Technical Safety BC's gas installation permit page confirms that it issues gas permits except in the municipalities with delegated authority, which do not include Coquitlam.
Coquitlam's own permits still matter to the project. The city's homeowner and residential building page says a permit is required for most new construction and for changes to an existing building, and the city's plumbing permits cover residential and other projects. The plumbing section accepts minor document submissions such as hydronic heating designs, which is where a replacement that alters the heating system touches the city process.
Who pulls the permits
The contractor applies for the Technical Safety BC gas permit, and the contractor or owner applies for the city permits that the scope requires. Technical Safety BC's homeowner gas permit route is available only to qualifying single-family owners; owners of strata and non-strata duplex dwellings must hire a licensed contractor.
Coquitlam's plumbing permits are handled digitally: the city accepts applications for commercial, institutional, industrial, multi-family and residential projects, and contractors applying for single-family, duplex, coach-home, renovation or addition permits do not need digital drawings. Hydronic heating design documents can be emailed to the plumbing section, which keeps the heating paperwork with the permit file.
What the inspection involves
The provincial gas permit carries the gas inspection: 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 inspection checks the installed gas work, venting and appliance installation against the code.
On the city side, Coquitlam books building and plumbing inspections through its online Inspection Booking System, and the city requires the approved drawings and printed permit to be on site for inspections. The city's process ties occupancy to a successful final inspection, which is the milestone that closes the permit file.
The replacement project, step by step
A Coquitlam replacement starts with an assessment and a heat-loss calculation, so the new boiler's output is set by the building rather than by the old appliance's rating. The equipment choice follows — condensing heating-only with an indirect tank, or a combi where space and hot-water demand suit — and then the permit path is confirmed for the property.
Installation covers the appliance, venting, condensate, gas and water connections, and commissioning with combustion readings. If the scope touches the hydronic design, the city's plumbing file carries the hydronic documentation alongside the provincial gas permit. Inspections close out both streams, and the handover files the records with the warranty registration.
- Assessment and heat-loss sizing
- Technical Safety BC gas permit for the appliance work
- Coquitlam building/plumbing permits where the scope requires
- Installation, venting, condensate and commissioning
- Inspections on both streams, then the records handover
What ROMA handles on a Coquitlam replacement
ROMA Heating & Cooling is a Technical Safety BC licensed gas contractor, lists Coquitlam among its service areas and publishes a Coquitlam page covering boiler installation, replacement, tune-ups and repairs. On a replacement, ROMA handles the assessment, the sizing, the permits, 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 Coquitlam city page links the services available in the city.
Coquitlam housing stock and boiler considerations
Coquitlam's neighbourhoods run from older homes in Maillardville and Austin Heights to newer builds on Westwood Plateau and Burke Mountain. Older houses often have conventional boilers feeding radiators or baseboards, and replacing them with condensing equipment usually involves a new vent route and a review of whether the emitters can run at lower water temperatures.
Newer homes and townhouses more often use wall-hung condensing boilers, combis or in-floor radiant loops, where controls and zoning do much of the work. Multi-family and commercial buildings bring plant-scale equipment into scope, where Technical Safety BC's boiler and pressure-vessel rules apply in addition to the gas permit. The assessment determines which of those situations the property is in.
