In Surrey, an event tent needs a City building permit once it exceeds 60 m² (646 ft²) of floor area. Under that size, the tent itself does not need one. The clause most hosts miss: a tent containing bleachers, stages, or sidewalls may require a permit regardless of its size, according to the City of Surrey.
That single line changes the answer for a lot of backyard weddings.
Which tent sizes actually cross the line
Run your footprint against the threshold before you book anything.
| Tent size | Floor area | Permit in Surrey? |
| 10 x 20 | 200 ft² | No |
| 20 x 20 | 400 ft² | No |
| 20 x 30 | 600 ft² | No, just under |
| 20 x 40 | 800 ft² | Yes |
| 30 x 60 | 1,800 ft² | Yes |
| 40 x 60 | 2,400 ft² | Yes |
A 20 x 30 is the largest common size that stays under the limit. A seated dinner for 80 or more guests almost always needs a 20 x 40 or larger, which means most real backyard receptions here land on the permit side of the line. Wedding planning articles telling BC couples that a 100-guest backyard event probably doesn’t need a permit are working from the wrong number.
The sidewall clause catches people
Sidewalls are not a decoration in the Lower Mainland. Book a September or October date and you will want them. Adding them can pull a tent that was comfortably under 646 ft² into permit territory, because the City’s wording is “may require a permit regardless of its size.”
“May” means the decision sits with the building department, not with you and not with your rental company. One phone call before you finalize the layout is cheaper than a stop-work conversation on setup day.
What Surrey asks for in the application
The application is a package, not a form. Expect to supply:
- Completed temporary tent permit application form
- Sealed and signed structural drawings covering the frame and the ground anchorage system, with a Schedule B from a registered professional
- A site plan and floor plan drawn to 1/8″ = 1′-0″, showing exits, aisle widths, occupant load, and washroom locations
- A letter from the property owner stating install and removal dates
- Documentation that the tent fabric conforms to CAN/ULC-S109-M or NFPA 701, which the tent supplier normally provides
- Authorization from Parks, Recreation and Culture if the tent goes in a municipal park
- The permit fee, calculated from the building bylaw fee schedule current at the time you apply
Three details worth flagging. A registered architect is required when the tent is used for assembly with an occupant load above 30 people, no matter the tent size. The tent has to sit at least 3 m (10 ft) from any other building or structure on the lot. And a temporary tent is only allowed on a lot for a maximum of one month in any 12-month period, with no extension or renewal, so a permit pulled for a July wedding blocks a second tent on that lot until the following year.
Vancouver’s rules are close, not identical
Vancouver uses the same 60 m² threshold, then adds requirements Surrey does not spell out the same way. Where multiple tents share a site, they must be no closer than 3 m apart, or a building permit is required regardless of tent size. The flame-resistance decal must be affixed in a prominent location and measure at least 75 mm in diameter, or 50 mm by 50 mm. An architect registered in British Columbia is needed once the tent area exceeds 275 m², per the City of Vancouver building bulletin.
Delta, Langley, Abbotsford and Richmond each run their own building department. The 60 m² figure comes from the BC Building Code and is widely used, but the paperwork, fees and turnaround are local. Confirm with the city where the event physically sits, not the city you live in.
Who supplies what
This is where bookings stall, so it is worth being blunt about the split.
Your rental company supplies the tent specifications, the flame-resistance certification and labels, and the anchoring method matched to your ground. On grass, that is staking. On a driveway or parking area, it is weighted ballast rather than stakes, since anchoring through pavement means drilling it.
You, or the property owner, supply the application, the owner’s letter, the fees, and the letters of assurance from the professionals the City requires. A rental company cannot pull a building permit on private property on your behalf. Any supplier who tells you the permit is “handled” is worth a second question.
How early to start
Work backwards from the event date, not forwards from today. Engineered drawings and City review both take time, and peak summer Saturdays across the Lower Mainland go out on hold months ahead. Six to eight weeks is a workable floor for a permitted tent, and earlier is better if your date falls on a long weekend. Black N’ White Tent Rentals holds marquee and frame tent inventory in Surrey, so sizing conversations can happen before the permit file is opened.
One check before you book
Measure the footprint you need, decide whether sidewalls are going on, then call the building department in the city where the event is happening and give them both numbers. If the answer is yes, ask your tent supplier for the flame-resistance certificate and the engineered anchorage drawings in the same conversation, so your permit file is not sitting idle waiting on a vendor email.
