What is the cost of hiring an engineer to stamp deck plans in NB?

Hiring a structural engineer to stamp deck plans in New Brunswick typically costs $800-$2,500, depending on the complexity of your deck and the engineer's scope of work.

Most residential deck projects don't require engineered plans unless you're building something unusual like a large elevated deck (over 8 feet high), a deck supporting a hot tub, or a complex multi-level structure. Standard attached decks up to reasonable sizes can usually be built using prescriptive methods from the NB Building Code without custom engineering.

When You Need Engineered Plans:

• Decks over 8 feet above grade


• Large spans requiring custom beam sizing


• Hot tub or heavy load support


• Unusual soil conditions or slopes


• Cantilever designs extending beyond normal limits


• Multi-level or complex geometric layouts


• When building officials require it due to site conditions

What Engineers Provide:
The engineer will create stamped drawings showing footing sizes and depths (accounting for NB's 1.2-1.5m frost depth requirements), beam and joist specifications, connection details, and load calculations. This ensures your deck can handle New Brunswick's snow loads (2.0-3.5 kPa depending on your region) and meets all structural requirements.

Cost Breakdown:

• Simple elevated deck review: $800-$1,200


• Complex multi-level design: $1,500-$2,500


• Hot tub platform engineering: $1,000-$1,800


• Site visit (if needed): Additional $300-$500

Finding Engineers:
Look for structural engineers licensed with Engineers and Geoscientists New Brunswick (EGNB) who have residential experience. Many deck builders in the New Brunswick Construction Network work with engineers regularly and can recommend someone familiar with deck projects.

The engineering cost is usually worth it for complex projects — it ensures safety, satisfies building officials, and can actually save money by properly sizing materials instead of over-building. Your municipal building department can tell you upfront if engineered plans will be required for your specific project.
