Is a second engineering opinion worth getting?

For a significant, complex, or unusually costly design, a second opinion can be a genuinely worthwhile investment — engineering, like any professional field, can involve legitimate differences in approach, and a second set of eyes can provide real reassurance or catch something worth reconsidering.

For a straightforward, standard residential design, a second opinion is less commonly necessary, though there’s no harm in seeking one if you have specific concerns about the proposed design or its cost.

If you do get a second opinion, share it constructively with your original engineer rather than treating it adversarially — genuine differences in engineering judgement can often be discussed and resolved directly between professionals.
