Altadena New Construction Through County Plan Check
New Construction in Altadena: county plan check for grading, foundation and ember resistance, fire access review, and work sequenced around inspections.
A Los Angeles County plan checker reviewing a new Altadena house starts with the site: where the footprint sits against the setbacks, how the grading plan handles cut and fill, and where storm water goes. Because Altadena is unincorporated, the county reviews the building, and its fire department reviews access and fuel modification. Altadena includes ground mapped as a fire hazard zone, so the envelope is checked for ember resistance too.
What the plan check covers
Structural review looks at the lateral design, the hold-downs and the foundation against the soils engineer's recommendations. The energy review checks the Title 24 compliance forms, and in a fire hazard area the reviewer reads vents, roofing, eaves, windows and siding for ember resistance. Where a lot slopes, the geotechnical report gets its own review, and the county may ask for added borings or a slope stability analysis before it signs off. We answer plan check comments in writing and track each one until the permit issues.
Ground work before framing
Work on site follows the approvals in order. Grading and any retaining walls go in early, then the foundation, which the county inspects before concrete is placed. Underground drains and the storm water outlet are set while the ground is open, because water left to run along a wall or under a slab causes trouble later that is costly to reach. Framing starts once the foundation inspection passes, and each later phase has its own inspection before it is covered up.

New Construction in Altadena: questions
The county wants a survey of lines and grades, a soils report and, where the lot slopes, a geology report, all feeding a grading plan. In a mapped fire hazard area the fire department also reviews a fuel modification plan and the driveway for engine access. We read these before we price the foundation.
A tight approach changes how concrete and framing arrive. When a truck cannot reach the forms, a pump does the work, and long beams may need a lift or crane. The county fire department may also require a wider or paved driveway, which becomes part of the site cost and its own quote line.
Yes, and the price is built to survive plan check. County comments can add hold-downs, deepen a footing or change a vent detail, so we note which lines rest on the current sheets and revise them against the approved set. Earlier involvement also lets access and footing choices shape the design.
