Waterproofing Services in Santa Monica

Santa Monica runs its own building department with a permit timeline that runs alongside LADBS but on a separate clock. North of Montana and the streets above Wilshire frequently fall under Coastal Commission jurisdiction. Salt-air corrosion, marine-grade fasteners, and copper or stainless flashings show up as defaults rather than upgrades. Older Sunset Park and Ocean Park bungalows (1920s–1940s) need full MEP work in any meaningful remodel.

Santa Monica sits in the California Coastal Zone, which means Coastal Commission review applies on top of standard permitting. We plan around that: typically 8–16 weeks of additional plan-check time depending on scope. Salt-air corrosion also drives material decisions: copper and stainless flashings, marine-grade fasteners, and assemblies engineered for marine exposure are the default rather than the upgrade.

Most Santa Monica homes were built before 1980. That means galvanized supply lines, undersized electrical panels, original gas runs, and rough-in plumbing that hasn't been touched in decades. Once walls open during a waterproofing services project, we expect to bring the underlying systems to current code, not as a surprise, as a plan.

Santa Monica runs its own permitting through City of Santa Monica + Coastal Commission (north of Wilshire). Plan-check timelines run on a separate clock from LADBS. We've worked through the local department often enough to know what their reviewers flag and what they wave through, so we submit the right drawing set the first time.
