ADU Design & Build in Loyola, California
Loyola's generous lots between Los Altos and the foothills support serious detached ADUs, guest houses, and pool-side retreats.
Building ADUs in Loyola, California
SHAPE designs and builds accessory dwelling units for homeowners in Loyola, California, across The streets around Loyola Corners, the Rancho San Antonio edge, and the orchard-era lots between Los Altos and the foothills.
Loyola combines Los Altos schools with larger, quieter county lots. Owners here build ADUs for multigenerational family, long-term rentals, and pool-side guest houses that match 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 Loyola building department.
Loyola ADU Rules at a Glance
- Setbacks: California state law caps rear and side setbacks for new ADUs at 4 feet, and Loyola 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: Loyola is an unincorporated Santa Clara County community that follows California ADU law, guaranteeing an ADU of at least 800 sq ft on qualifying lots, with larger units subject to county lot coverage and height rules.
- 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 Loyola lots.
SHAPE handles the full permit package with the Loyola planning department, zoning verification, building plans, Title 24 energy, and every correction cycle, so you don't have to learn the code.
Our Process
- Site assessment. We walk your Loyola lot, confirm setbacks and utility locations, and give you a feasibility read and an all-in price the same week.
- Design. Our in-house architects design the ADU around your lot, your family, and your budget, with fixed pricing before you sign.
- Permits. We submit, respond to every planning and building comment, and drive the file to permit issuance with Loyola.
- Build. Modules are fabricated in our facility while site work, foundation, utilities, landscaping, runs in parallel. Set and finish happen on site.
