The honest answer

Understand common triggers such as wall removal, additions, foundations and unusual framing. Those details are where vague proposals become expensive. If a proposal names when a structural engineer may be needed but does not address them, the price is not ready to trust.

Plan review is the agency's document check before work is approved to begin. An inspection is the field check of visible work during construction; one does not replace the other.
