ADU Construction in Rolling Hills
Serving 90274 and Rolling Hills Estates, Rancho Palos Verdes, Palos Verdes Estates
Rolling Hills lots have the two things an ADU wants most — land and privacy — and one thing that shapes everything else: a fiercely protected single-storey character. A second dwelling here is a low pavilion sited with care, not a stacked unit. The approval path is doubled the way all Rolling Hills work is: the community association's rules on one side, and plan check through Los Angeles County's Lomita office or Willdan on the other, before a spade turns on those private roads.
Real projects. Real prices.

Second dwellings on view acreage
Siting is the design
On view acreage the ADU's position decides its worth: below the sight-line of the main house, oriented to its own slice of the outlook, reached by a path that makes sense in rain. We site with stakes and story poles before drawing walls.
Low, and belonging
A second structure in this city must read as part of the ranch composition — matched roof pitch, compatible materials, planting that stitches it in. The association reviews character; good design answers before being asked.
Where the services run
Large parcels mean long utility runs, and hillside edges mean drainage design. Trenching routes, meter capacity and septic-or-sewer questions get engineered early because they are the part of an ADU budget nobody sees coming.
County plan check for the new structure
A new dwelling gets full structural, energy and life-safety review through the county path the City uses — Lomita's counter or Willdan. New-build drawings are the cleanest kind of submittal when they arrive coordinated.
Sideways, never upwards
The city protects a low, single-storey ranch character, and height is regulated by the community association rather than by the permit office. For a second dwelling that is a design instruction rather than an obstacle: the building spreads instead of stacking, its roof stays quiet against the ridgeline, and the space it gains comes from footprint and from clever section rather than from a second floor. On parcels of this size that is entirely achievable, and the results are frequently better than a taller building would have been — long, low, well-oriented structures that sit into the land rather than standing on it. Designing to that discipline from the first sketch avoids the most common and most expensive rethink here.
