Deck and Porch Engineering
Stamped deck and porch plans and calculations for elevated, large or nonstandard designs outside prescriptive code tables.
What the work involves
An engineer designs the deck framing, beams, posts, footings, ledger attachment and lateral connections, and stamps plans for the permit. Many simple decks can be built from prescriptive code tables or local deck guides, but elevated decks, long spans, hot tubs, roof decks and decks on slopes typically require engineering. The engineer also evaluates whether an existing deck is safe when it shows rot, sagging or loose ledgers.
Local conditions we plan for
- Coastal flooding and storm surge in New York City and Long Island
- Frost depth and heavy snow upstate
- Aging infrastructure, bridges and older buildings
- Lake effect snow loads in western New York
Building code: 2024 IBC/IRC adopted at the state level (ICC adoption chart, April 2026).
When you need it
- Deck height or span exceeds the local prescriptive deck guide
- Hot tub, outdoor kitchen or heavy planters on the deck
- Second-story or rooftop deck
- Deck on a steep slope or cantilevered over a hillside
