“Structural surprises are the #1 budget risk in 1950–1975 Valley homes. When we open walls, we frequently find: unapproved additions, undersized joists, no seismic straps, galvanized plumbing that's corroded to failure. We build a 15% contingency into every full renovation budget for this reason — not as a cushion, as a necessity.”
