Does New Westminster require a permit to replace a gas boiler?
Yes, and New Westminster has one of the more detailed hydronic permitting processes in the region. The city's hydronic heating guide states that a hydronic heating permit is required to install a new hydronic heating system or to alter or extend an existing one, and that permits are not required for minor repairs to leaks in hydronic systems or for regular scheduled maintenance. A boiler replacement that alters the system falls on the permit side of that line.
The gas appliance side is provincial. Technical Safety BC's gas installation permits page lists the municipalities that issue their own gas permits, and New Westminster is not among them, so the gas permit for the boiler comes from Technical Safety BC. A replacement therefore runs with a city hydronic heating permit and a provincial gas permit.
Who pulls the permits and what the application needs
The application is document-heavy by design. The city's guide requires evidence of plumbing trade qualification for contractors, a current City of New Westminster business licence, evidence of home ownership for homeowners, and an approved building permit. It also requires an appliance worksheet, a heat loss summary, a hydronic radiant floor panel worksheet, and a boiler room layout diagram sealed, signed and dated by a Certified Hydronic Heating Designer.
The city's plumbing department reviews and processes the application in a minimum of 48 hours, a timeline the city says can extend with application volume, complexity or accuracy. Once accepted, the hydronic heating permit is emailed to the applicant. Technical Safety BC's homeowner gas permit route remains limited to qualifying single-family owners, and the contractor applies for the provincial permit in the normal course of the job.
What the inspections involve
New Westminster defines the inspection stages for hydronic work. Radiant floor panel inspection: all in-slab piping must be inspected and approved before slab preparation and pour continue. Baseboard rough piping inspection: baseboard piping loops above and below slab must be inspected and approved before proceeding. Final hydronic heating inspection: all appliances and system components must be installed, cleaned and fully operational as per the designer's criteria, with the Certification of Heating Systems form on site.
On the gas side, the provincial permit carries its own process: 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 deciding whether a physical assessment is needed. The two streams meet at the end of the project, where the hydronic system's final inspection and the gas permit's completion record close out the work.
The replacement project, step by step
A New Westminster replacement starts with the assessment and the heat-loss work the city's application requires, because the hydronic permit documentation is built from it: the appliance worksheet, heat loss summary and boiler room layout all come from the design stage. The equipment and hot-water strategy are chosen, the Certified Hydronic Heating Designer seals the layout, and the permit applications follow.
Installation proceeds through the inspection stages — in-slab piping before any pour, baseboard loops before closing, then the final inspection with the certification form on site. Commissioning with combustion readings closes the gas side, and the handover files the hydronic permit, the gas permit record and the warranty registration together.

What ROMA handles on a New Westminster replacement
ROMA Heating & Cooling is a Technical Safety BC licensed gas contractor and lists New Westminster among its service areas, with a dedicated New Westminster page covering boiler installation, repair and maintenance. On a replacement, ROMA handles the assessment, the design documentation the city's hydronic permit requires, 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 New Westminster city page links the services available in the city.
New Westminster housing stock and boiler considerations
New Westminster has some of the oldest housing stock in the region, from heritage homes around Queen's Park to long-established houses on the hillside, alongside newer waterfront towers and townhouses. Older homes often have hydronic systems that have been modified over the years, which is exactly the situation the city's hydronic permit process is designed to document: the system is reviewed as a design, not just as a connection.
The city's requirement for a Certified Hydronic Heating Designer's seal on the boiler room layout is worth planning for early, because it makes the design step part of the critical path. For owners of older homes, a replacement is also an opportunity to correct legacy zoning and control issues while the system is open.
