Frequently Asked Questions
**What's the cheapest structural engineering option?** A calculation letter for simple projects (single beam, header) is typically the most affordable option, starting around $350-$500.
**Can I do structural work without an engineer?** Not legally for most projects in California. Building departments require PE-stamped plans for structural modifications.
**Why do prices vary so much between engineers?** Differences in scope, experience, overhead, and approach. Always compare equivalent scopes when evaluating prices.
**Is it worth getting multiple quotes?** Yes, for larger projects. For simple calculations, the time investment may not justify savings. We provide competitive quotes on first contact.
