ADU Design & Build in Ladera, California
Ladera's wooded hillsides and mid-century character call for an architect-led ADU that sits lightly on the land and respects the landscape.

Building ADUs in Ladera, California
SHAPE designs and builds accessory dwelling units for homeowners in Ladera, California, across The hillside streets off Alpine Road, the Ladera Community Center area, and the wooded lots bordering Portola Valley.
Ladera homeowners value privacy, views, and mid-century character. ADUs here are usually guest suites, studios, or in-law units designed to disappear into the oaks rather than compete with the main home.
We're a licensed California general contractor (CSLB #1158688) with an in-house architecture and modular construction team. That means one contract, one fixed price, and one team responsible from the first site walk through final inspection with the Ladera building department.
Ladera ADU Rules at a Glance
- Setbacks: California state law caps rear and side setbacks for new ADUs at 4 feet, and Ladera follows that standard.
- Height: Detached ADUs are generally allowed up to 16 feet, or up to 18–25 feet on lots that meet transit or multi-story criteria under state law.
- Maximum size: Ladera is an unincorporated San Mateo County community that follows California ADU law; hillside lots typically require geotechnical review and careful grading plans, which SHAPE handles inside the design package.
- JADUs: Junior ADUs (up to 500 sq ft) are allowed inside the existing footprint of the primary home, in addition to a detached ADU on most single-family lots.
- Parking: No replacement parking is required when an ADU is built within one half-mile of public transit, which covers most Ladera lots.
SHAPE handles the full permit package with the Ladera planning department, zoning verification, building plans, Title 24 energy, and every correction cycle, so you don't have to learn the code.
