What a seismic retrofit (foundation) permit usually covers
Usually anchor bolts, cripple wall bracing and hardware the inspector checks. Engineering reports, foundation replacement and finish work are often separate.
Read this first. Permit values are self-reported by the applicant to set permit fees. They often leave out materials or labor, and they are not what the contractor actually charged. A quote above or below this range can be reasonable.
