New Construction in Altadena
New home construction in Altadena, with eaves, vents, walls and glass chosen for ember-resistance rules and plans reviewed by Los Angeles County.
"Do the eaves have to be boxed in?" We answer it on the first walk of an Altadena lot, because the reply shapes the roof drawings. Altadena includes ground shown on fire hazard maps, and a parcel shown there may owe ember-resistance details at its eaves. Open rafter tails can stay in a design when the exposed underside is built from materials the code accepts.
Roof, vents and walls
On a mapped lot we build the roof as a Class A assembly, and the gutters need a way to keep leaves from piling up. Attic and crawlspace vents carry a listing for ember and flame intrusion. Exterior walls can be clad in noncombustible or ignition-resistant material, or in an assembly tested to the standard, which leaves room for cement plaster, fiber cement or fire-retardant-treated wood. Windows qualify with dual panes where at least one pane is tempered. Deck boards attached to the house carry their own ember-resistance requirement as well.
A county permit
Altadena is unincorporated, so Los Angeles County Public Works handles plan check, the permit and building inspections. Where the parcel is mapped, the county fire department may also review a fuel modification or planting plan, and that review runs alongside the building one. New houses in California need fire sprinklers, so the water service is sized for them from the start. We draw the ember-resistant details into the first set, which keeps a material swap from forcing a resubmittal later. The county's comments come back to us and the designer together.
New Construction in Altadena: questions
County zoning and the lot's fire mapping decide it. Zoning sets height, setbacks and coverage. If a mapped fire hazard zone covers the parcel, roof, vents, eaves, walls and windows follow ember-resistance rules, and the site plan may need a vegetation clearance. With both checked, we can say what fits. Clearing a structure already there can join our scope.
Early design yields a first budget number. Once the drawings can be priced, the written quote sets out each phase in order, and ember-resistant choices for vents, eaves, glass and cladding sit on lines of their own, so you can see what each one adds.
Los Angeles County Public Works reviews and permits building in Altadena, which has no city government of its own. On a mapped lot, the county fire department may look at vegetation as well. Your designer and engineer can prepare the sheets, or we bring ours in. We file, answer county comments and call inspections as phases finish.
