ADU Construction in Palo Alto

Atlas General Construction (CSLB #1059664) builds ADUs throughout Palo Alto — from the historic Professorville district to Eichler neighborhoods in Green Gables and Duveneck. We combine deep regulatory knowledge with proven construction excellence to deliver Palo Alto ADUs on time and within budget.

Palo Alto’s ADU permitting process is among the most detailed on the Peninsula, with requirements including tree protection plans (Sheet T-1), Substantial Remodel triggers, and strict noise ordinances. Our team navigates all of this proactively.

Tree Protection (Sheet T-1): Palo Alto’s protected canopy often affects ADU siting. We integrate arboricultural planning from day one to prevent permit delays.

The 50/50/50 Substantial Remodel Rule: Replacing more than 50% of exterior walls triggers whole-house electrification mandates. We help you plan around these thresholds.

Noise Ordinance: Construction hours are 8 AM–6 PM weekdays. We schedule accordingly and communicate proactively with your neighbors.

R-1 Zoning Setbacks: Palo Alto has specific rear and side setback requirements for ADUs. We confirm feasibility before you invest in design.

Eichler ADUs: We specialize in ADU construction that respects the unique open-plan, glass-wall character of Palo Alto’s beloved Eichler homes.

Detached ADUs: Ideal in neighborhoods like Barron Park, Midtown, and South Palo Alto where lot sizes support rear-yard structures.

Garage Conversions: Many Palo Alto garages qualify for conversion to full living units. Fastest permit path and most cost-effective ADU option.

JADU (Junior ADU): Internal conversion of existing space up to 500 sq ft — no exterior construction required.

Typical Palo Alto ADU rental income: $3,500–$7,500/month.
