The hardest part of a mechanical permit is knowing where to file it. Mechanical work is split across two authorities — gas goes to Technical Safety BC, building systems go to the municipality. Get it wrong and you lose time at the wrong counter.
What Is a Mechanical Permit in BC?
A Mechanical Permit is required for any work involving HVAC (Heating, Ventilation, and Air Conditioning) systems in a building. This includes ductwork, air handling units, exhaust systems, and related mechanical equipment. Whether you’re working on a new commercial build or a Tenant Improvement (TI), a Mechanical Permit is almost always part of the permit package. It’s typically issued in connection with the Building Permit and applied for by the mechanical subcontractor.
⚠️ Two Separate Authorities
| Scope | Authority | Basis |
|---|---|---|
| Gas appliances, gas piping, venting | Technical Safety BC | Gas Safety Regulation |
| Ventilation, A/C, heating systems, chimneys | Municipal building dept. | City building bylaws |
| Hydronic heating tied to plumbing | Municipal plumbing dept. | City plumbing bylaws |
Within one “mechanical” scope, gas lines are TSBC while ductwork and HVAC units are the city. One project routinely needs two permits.
Vancouver Mechanical Permit Fees
| Type | Fee |
|---|---|
| Single private residential deck, patio or balcony | $263.00 |
| Building 1–3 storeys | $432.00 + $15.30 per kW |
| Building 4 storeys and above | $985.00 + $122.00 per electric heat pump above 6 units (max $2,500) |
Note the logic shift: 1–3 storeys is priced on capacity (kW), 4+ storeys on heat pump count. On low-rise, fees scale linearly with capacity — trimming kW at design stage trims the permit fee with it.
A 100 kW system in a 3-storey building runs $432 + (100 × $15.30) = $1,962.00. Ten heat pumps in a 4-storey building runs $985 + (4 × $122) = $1,473.00.
Separately, Vancouver assesses chimneys, fireplaces, incinerators, ventilating, air-conditioning and heating systems on the building fee scale — but charges nothing when the work costs under $500.
TSBC Gas Permit Fees (2026–2027)
| Item | From Jan 2026 | From Jan 2027 |
|---|---|---|
| Install/replace 1–2 appliances (incl. vent and gas piping) | $164 | $172 |
| Each additional appliance | $80 | $84 |
| Venting only, no appliances | $80 | $84 |
| Gas piping only, no appliances | $66 | $69 |
| Gas connection to mobile building | $124 | $130 |
Gas permits include a maximum of two inspections — the tightest allowance of any TSBC permit type (service electrical gets five, alterations three). Overages bill at the Safety Services rate: $212 minimum, $424 on weekends and holidays.
Surrey Heating-Related Fees
| Item | Fee |
|---|---|
| Heating (hydronic) — per 1,000 BTU input | $5.30 |
| Maximum heating charge | $679.00 |
| Space heaters / chimneys (building dept.) | $119.00 |
| Re-inspection | $240.00 (each) |
| Preliminary or special site visit | $240.00 |
Surrey prices heating on BTU input. A 128,000 BTU system works out to 128 × $5.30 = $678.40 — essentially at the $679 cap. Large systems benefit from the cap; small ones pay actual cost.
Coordination Notes
Mechanical needs to win the ceiling. Ductwork is the bulkiest service up there, so it should be routed before sprinkler, cable tray and piping. Reverse that order and the rework is expensive.
- File gas and building separately. TSBC and the city are independent processes on independent timelines
- Gas includes only two inspections. Beyond that, $212 minimum each
- Do not file before kW/BTU is locked. Vancouver prices on kW, Surrey on BTU
- Fix duct routing first. Other services going in ahead of it is costly to undo
- Back-schedule commissioning from occupancy. No mechanical final, no occupancy

Vancouver fees per the City of Vancouver 2026 Schedule of Fees (effective January 1, 2026); TSBC per the Electrical & Gas – Homeowner Fee Schedule (FSHO-969-04, updated January 19, 2026); Surrey per its plumbing and building fee schedules.
Who Issues It and When
Mechanical Permits are issued by the Building Department of the relevant city or municipality — the same authority that issues the Building Permit. On commercial projects, the Mechanical Engineer (P.Eng) acting as Engineer of Record (EoR) is required to stamp the mechanical drawings and submit Schedule B (Mechanical), confirming design responsibility. The mechanical subcontractor submits the permit application and is responsible for ensuring it’s approved before beginning work.
Required Submission Documents
A Mechanical Permit application for a commercial project typically requires the following: Mechanical drawings stamped by a P.Eng (submitted with or after the Building Permit application), an Equipment Schedule listing brands, models, and capacities for all mechanical equipment, Ventilation Calculations demonstrating compliance with BCBC Part 6, Schedule B (Mechanical) signed by the Engineer of Record, and in some cases an Energy Compliance Report confirming the design meets BC’s energy efficiency requirements.
Inspection Stages
Once a Mechanical Permit is issued, the work is subject to staged inspections by a city inspector. The key inspection milestones are the Rough-in Inspection (before ductwork or piping is concealed), the Insulation Inspection (after insulation is installed on mechanical systems), and the Final Inspection (once all mechanical systems are complete and operational). As a PC, coordinating these inspection dates with the mechanical subcontractor is part of the job — inspectors arriving to find work not ready for inspection can result in failed inspections and re-inspection fees that delay the schedule.
What PCs Need to Watch For
One of the most common PC oversights on permit management is assuming that once the Building Permit is issued, the subcontrades are handling their own permits. Always confirm directly with the mechanical sub that their Mechanical Permit has been applied for and is in progress. Work proceeding without a permit can result in stop-work orders, fines, and costly re-inspection or demolition requirements.
Schedule B submission requires coordination with the Mechanical Engineer — they need to physically sign and submit the document, which takes time. Build this into your permit tracking schedule. Mechanical Permit processing times vary by municipality and project complexity, but typically range from two to six weeks. Getting the application in early prevents the permit from becoming a scheduling bottleneck.

Before You Apply: Checklist
- Confirmed with your municipality that the work needs a mechanical permit?
- Prepared mechanical drawings and equipment specifications?
- Verified you are using a qualified technician?
- Reviewed the application fee and expected processing time?
- Scheduled so the rough-in inspection happens before anything is covered up?
Fees, Processing Time, and Field Notes
Mechanical permits are issued by the municipal Building Department, and fees vary by municipality. They are typically calculated as a percentage of the mechanical construction value, though some municipalities use a flat fee or a mix of both. Because there is no single province-wide fee table, confirm the exact amount with the Building Department of the city where the project is located. Since the mechanical permit is usually tied to the Building Permit, its fees and review timeline often depend on the Building Permit application schedule.
Processing time follows the Building Permit review when applied together, so a delayed HVAC design pushes the whole permit back. A frequent field issue is a mismatch between the ventilation calculations and the actual installed equipment capacity. If the model on the Equipment Schedule changes (for example, a substitute is ordered), the Field Review stage requires re-review and the schedule slips. Whenever equipment orders change, notify the Mechanical Engineer (EoR) immediately to keep the Schedule B (Mechanical) consistent — this is the key to avoiding delays.
