San Marino issues its own permits: siding and stucco work goes through the City of San Marino Community Development Department, Building and Safety Division at City Hall, 2200 Huntington Drive, not LADBS. A like-for-like re-side or re-stucco is a simpler permit than a conversion or a wall that needs framing repair, which goes to plan check.
San Marino's design review ordinance, Chapter 23.15 of the Municipal Code, covers exterior changes visible from the street, and the City publishes a Good Neighbor Guide to the process; a like-for-like re-stucco in the original finish is the simplest path, a change of material or profile goes to design review first.
We prepare whichever review comes first, submit the permit, schedule the inspections, meet the inspector at the flashing stage and at the final, and close the permit before the final payment. You keep the closed-permit record.
