Our office has NEVER accepted redwood as a structural component (beams, joists) for decks as we have always understood that redwood had no structural value. Today I received an e-mail from a permit applicant stating that he had an engineer who will ok the use of redwood for his deck joists and support beams. I am reluctant to accept this proposal (even if signed and sealed) and am seeking opinions from this forum of respected experts! Any thoughts/advice?
