Topic Overview
Structural improvements include anything that changes load paths, shear resistance, or code-minimum capacity—often discovered mid-project when older homes are opened up. National calculators rarely capture every structural unknown, so ranges should be treated as starting points.
What To Review First
- Whether existing deck or roof assemblies show decay or deflection
- Engineer or architect involvement triggers and typical fees
- Code upgrades triggered by permits (not just like-for-like replacement)
- Contingency for hidden conditions once surfaces are removed
