ADU Construction in Palos Verdes Estates, Grounded First

Palos Verdes Estates ADUs planned from a level survey of the yard, with footings fitted to the soil, finishes for ocean air and a kitchen drawn first.

A laser level set up in the yard gives us our first reading on a Palos Verdes Estates lot. We shoot the ground at each corner of the planned unit and at the back wall of the house. Those readings tell us whether the footprint is flat or calls for a stepped footing, which way rainwater will want to run and how high the finished floor should sit. With them in hand, the foundation is settled before the kitchen goes on paper.

Footings matched to what the ground shows

Readings close to level point to a slab on grade with thickened edges under the walls. Where the survey shows a drop, a raised floor on short stem walls follows it, and the reviewer may ask for a soils report before the footing design is final. In both cases the finished floor stays above the surrounding ground, and the soil is graded to carry water away from the walls. A raised floor also leaves a crawl space where the kitchen drain and supply lines can run with no trench cut through concrete.

Finishes for a lot near the ocean

Moist ocean air settles on every exterior surface, so the skin of the unit is chosen to shed it. Cement plaster with a dense finish coat or fiber cement lap boards cover the walls, trim is a material that cannot rot, and fasteners are stainless. Fiberglass window frames hold their finish, and exterior light fixtures carry a wet-location rating. The heat pump condenser sits on a raised pad with a coated coil, and the dryer and hood vents get stainless caps fitted with backdraft dampers.
