ADU Construction in Pacific Palisades
ADUs in Pacific Palisades planned from moisture readings on the older house, with coastal and fire hazard rules checked before the unit is designed.
Our first probe on a Pacific Palisades lot goes into the older house's lowest wood. A moisture meter on the sill plates and lower siding, and an awl pressed into any soft spot, show how damp air and drainage act on wood at that address. Those readings tell us which side of the yard stays wet, where the ADU should not sit, and how its own walls and framing near the ground need protecting.
Reading the wood and the ground
High readings low on the house wall can point to soil piled against the siding, a downspout emptying at the foundation or a missing vapor barrier in the crawl space. Whatever the cause, the lesson carries to the new unit. The ADU sits on a foundation that lifts its framing clear of the soil, with treated sill plates, a capillary break under the slab and grading that falls away from both buildings. If the lot slopes, drainage above the unit gets the same care.
Coastal and fire review on the same lot
LADBS issues the building permit for a Pacific Palisades ADU. A lot here may also lie within the coastal zone, and that can bring its own approval step ahead of the permit, and parts of the area are mapped for fire hazard. On a mapped lot the unit needs a roof rated Class A, ember-screened vents and walls of ignition-resistant material. Near the coast, airborne salt corrodes plain steel, so fasteners and flashing go in stainless or coated metal. Both the coastal and fire status are confirmed on city maps before design.

ADU Construction in Pacific Palisades: common questions
The panel, the sewer lateral and the water service are each checked before the unit is placed. A small or dated panel may be replaced, or LADWP may set another meter for the unit. Camera footage of the lateral shows any cracked clay or roots, and if the unit's drain cannot reach it by gravity, a small pump becomes part of the plan.
It may, if the structure is sound and the lot's rules allow it. We take moisture readings on the garage's sill plates and lower walls, check its slab and roof, and confirm whether a mapped fire hazard area calls for new cladding and vents. When the old shell cannot pass, we rebuild on the same spot.
We keep the main house in view: its roof form, eave depth, window style and siding. Each is carried onto the unit at a smaller size, using materials that meet fire and coastal requirements while matching the original texture and color. The goal is a building that looks as if it has always stood beside the house.
