Restaurant Patio Enclosures | Extending the BC Dining Season
In BC, a properly designed patio enclosure can extend a restaurant's usable dining season by 4 to 6 months per year. This guide covers the component systems, code requirements, and ROI considerations for hospitality operators.

The economics
A 1,000 sq ft patio in Vancouver typically operates 3 to 5 months without weather protection and 10 to 12 months with proper enclosure. The delta is significant revenue; in many cases the enclosure pays back within 18 to 30 months.
The enclosure also lets operators plan staffing, reservations, and events without weather uncertainty, arguably as valuable as the incremental seats.
The four component systems
A full-function year-round patio typically combines four systems:
- Overhead: louvered roof or motorized glass roof. Closes against rain, opens for sun, with integrated gutters.
- Side walls: zip screens or motorized glass walls. Zip screens are most common; they seal against wind and rain while preserving visibility, and fully retract when weather allows.
- Heating: overhead electric infrared or gas radiant heaters. Infrared warms people, not air, which is critical for partially-open patios.
- Fabric: FR-rated (Sunbrella Firesist, Exceed FR) per hospitality code. Specify color and pattern to match brand.
Code considerations
Restaurant patio enclosures in BC must meet several overlapping requirements:
- Fire-retardant fabric (CAN/ULC-S109 or equivalent) for all fabric components in the assembly
- Structural compliance with BC Building Code wind and snow loads for the municipality
- Occupancy classification changes: a fully enclosed, heated patio may re-classify the space; confirm with the municipality early
- Liquor license patio area definitions: BC LCRB rules on patio boundaries, enclosure, and signage apply
- Accessibility: new or significantly modified commercial spaces must meet current accessibility requirements
Design pitfalls we see
Common mistakes to avoid:
- Under-spec'd heating: ambient heaters cool fast in open-side patios; specify infrared and size generously
- No wind automation: patios without wind sensors require manual operation, which doesn't happen reliably during service
- Poor drainage: louvered roof gutters must be tied into the storm system properly; water on the sidewalk is a liability issue
- Non-FR fabrics: every fabric element in the assembly needs FR documentation to satisfy inspectors
- Ignoring noise: a closed patio can amplify ambient noise; specify acoustic fabric or wall treatments if the neighborhood is noise-sensitive
Frequently Asked Questions
What's the difference between a 'hot tent' and a proper patio enclosure?
A hot tent is a temporary rental structure with a portable heater: it creates a covered outdoor space but is weather-limited, inefficient to heat, and generally cannot be left in place year-round. A proper patio enclosure uses permanent or semi-permanent engineered systems (louvered roof, zip screens, integrated heating) that operate reliably across seasons and typically last 15 to 20 years.
How much does a full restaurant patio enclosure cost?
Highly project-dependent. A modest 500 sq ft patio with louvered roof, zip screens, and heating typically starts around $60,000 to $120,000 installed. Larger patios with glass roofs, full side walls, and premium fabrics range $150,000 to $400,000+. The enclosure is a capital investment; typical ROI calculations use incremental revenue from extended-season operation.
How long does installation take for a restaurant?
From signed order to commissioned patio is typically 10 to 16 weeks: approximately 6 to 10 weeks for manufacturing and lead time, plus 1 to 3 weeks on site for installation and commissioning. Permits and design review can add additional time up-front. We generally work with operators to sequence installation during slow periods to minimize operational impact.
