Why deck load calculations are required

Structural calculations verify that every component of a deck can safely support anticipated loads without excessive deflection or structural failure.

Our licensed structural engineers provide complete deck load calculations for residential, commercial, rooftop, balcony, terrace, patio, and elevated decks — prepared per the applicable building codes, engineering standards, and local jurisdiction requirements to ensure safety, durability, and permit approval.

Loads we evaluate

Every load, calculated.

Dead Load (DL)

  • Deck boards, joists & beams

Live Load (LL)

  • Residential decks: 40 psf
  • Residential balconies: 60 psf
  • Commercial decks: 100 psf
  • Assembly areas: 100 psf+
  • Roof decks per code & occupancy
