Stucco & Exterior Walls in Mar Vista
Mar Vista stucco work laid out around the City of Los Angeles lath inspection, with the layers left open for review and trim metal picked for salt air.
Permits for stucco work in Mar Vista go to the City of Los Angeles building department, and inspectors there stop a job at a fixed point: after the paper and lath are on and before any plaster covers them. That hold shapes how a re-stucco is scheduled, because the layers must stay open until someone has looked. Small patches that need no permit skip the stop.
The hold before the plaster
Inspectors look at layers they will never see again. The weather-resistive paper must lap shingle-fashion, upper courses over lower ones, and turn into every opening. The lath is fastened through to the framing at the spacing the code sets, with its laps and corners tied. The weep screed sits at the base where water can leave. We lay all of it out ahead of the inspection, leave the wall open and photograph each section before it disappears, so the approval attaches to a wall the reviewer actually saw.
Trim metal near the water
Metal accessories on a Mar Vista wall get more thought than on an inland one, because corrosion at a bead or screed lifts the plaster from behind. Galvanized lath and trim meet the code floor. Where a wall takes salt air, zinc coatings can be specified heavier, or casing beads and screeds can be vinyl, which cannot rust. The finish coat is matched from a test patch on the wall itself, since color and texture read differently on weathered plaster than on a sample chip held beside it.
Stucco & Exterior in Mar Vista: common questions
Noncombustible is the test, and cement plaster over lath passes it, as does a listed fiber cement siding. The covering also has to run unbroken from the foundation to the roof or the eave enclosure. Where a wall falls under the wildfire chapter, a reviewer reads those ends as closely as the finish.
Knock on the wall with a knuckle. A solid sound, hairline cracks and no stains mean a patch will hold. Hollow patches, stains bleeding from within, soft spots at openings or paper that crumbles when exposed call for stripping that section and rebuilding the layers. A small test window is cut first and the findings go on the written scope.
The screed is the bottom edge of the plaster and needs open space below its flange. Soil, mulch or a slab that has crept up against it is cut back, plaster that bridged over the flange is chipped away and the drip line is restored. The exposed edge is then repaired so water has a clean exit at the foot.
