Crawlspace and seismic checks in Simi Valley

Aspenwell Construction starts a Simi Valley visit at the foundation vents, then checks anchors, cripple walls and ember rules before writing a scope.

Our Simi Valley visits begin at the foundation vents, which we read from outside before the crawlspace hatch is opened. A crushed screen lets in animals, and a vent buried by soil or planting traps moisture against the sill. On a lot inside a mapped fire hazard zone, an older vent with coarse mesh matters too, because ember rules may apply once the work touches it.

Under the floor after the vent walk

Inside, we follow the sill from one corner to the next, counting anchor bolts and marking each gap on the sketch. Cripple walls are measured for height, and an awl tells sound framing from rot or insect damage near any vent that let in water. An inland valley lot can bake dry for months and then soak during a hard storm, so foundation cracks are measured and logged with their widths. Downspouts that empty against the wall go into the scope as well, because that water keeps working on the footing after the bracing is done.

Ember resistant vents and the city review

Parts of Simi Valley sit inside mapped fire hazard zones. On a lot there, replacement vents can be a type listed to resist embers and flame, and new material at the base of an opened wall can be noncombustible. The anchors, plywood and post connectors go in first, and the new vents are fitted once the bracing is nailed off. Plan review and inspection run through the city of Simi Valley, whose inspector checks the hardware before the crawlspace is closed. A final visit signs off the permit once every stage has been seen.
