What engineering costs

Most residential structural plan sets fall between $1,500 and $5,000. Light commercial MEP design typically runs $5,000 to $25,000+ depending on scope. PE stamping of completed plans is usually a fraction of full design fees — get a quote and see.

What drives the price

Scope, complexity, and jurisdiction. Complicated structures, tight sites, and strict plan-check departments cost more everywhere. Simple projects shouldn't.
