What does engineered drawings cost for a Vancouver deck permit $?

Engineered drawings for deck permits in Metro Vancouver typically cost $500-$2,000, depending on the deck's complexity, height, and structural requirements.

The cost varies significantly based on several factors. Simple elevated decks (8-12 feet above grade, standard rectangular shape, straightforward beam and joist layout) usually fall in the $500-$800 range. Complex multi-level decks, curved designs, or decks requiring custom structural solutions can reach $1,500-$2,000. Decks over 16 feet above grade or those supporting hot tubs, outdoor kitchens, or heavy planters require more detailed engineering calculations and fall toward the higher end.

When engineered drawings are required depends on your municipality and deck specifications. Most Metro Vancouver cities require engineered drawings for decks over 10-12 feet above grade, though some require them for any deck over 600mm (2 feet). Decks with unusual spans, cantilevers, or complex geometry typically need engineering regardless of height. Hot tub platforms always require engineering because a filled hot tub weighs 3,000-5,000 pounds concentrated in a small area.

Strata properties often have additional requirements — many strata corporations require engineered drawings for any deck modification, even ground-level projects, as part of their alteration agreement process. This adds to the timeline but protects both the homeowner and the strata from structural liability.

The engineering process typically takes 1-2 weeks once the structural engineer receives your deck plans and site measurements. The engineer will specify beam sizes, joist spacing, post foundations, connection hardware, and lateral bracing requirements to meet BC Building Code standards for both gravity loads and seismic forces. BC is an active seismic zone, so elevated decks require specific lateral bracing and connection details that a structural engineer must calculate.

This cost is separate from your building permit fee ($200-$800 depending on municipality) and is paid directly to the structural engineer. Many deck contractors work with specific engineers and can coordinate this for you, though you're free to hire your own. The engineering cost is typically 2-5% of your total deck project cost — a worthwhile investment for safety and code compliance.

When to hire the engineer: Get your engineered drawings completed before applying for your building permit. The municipality needs the stamped drawings to review your permit application. Most contractors prefer to have the engineering done early in the planning process so they can price the project based on the actual structural requirements rather than estimates.
