Palo Alto new construction permits.
What it actually takes to permit a ground-up build in Palo Alto: jurisdiction, plan check, inspections, and the local overlays that change the path. Every link below points at an official City of Palo Alto Planning & Development Services — Building Division resource.
Quick answer
New single-family permits in Palo Alto are issued by City of Palo Alto Planning & Development Services — Building Division; California Title 24 Part 6 and CALGreen Part 11 apply statewide on top of any Palo Alto reach-code amendments.
Homeowner & investor takeaway
Engage CPAU early on service capacity and treat the protected-tree survey as a feasibility input, not a checkbox. Second-story projects almost always trigger Individual Review noticing.

Permit types typically involved.
Building permit
Required for a new dwelling unit, including structural, MEP, and envelope review.
Grading / drainage
Grading thresholds and Low Impact Development (LID) stormwater requirements apply per City of Palo Alto Planning & Development Services — Building Division; sloped parcels require geotech and an erosion-control plan.
Sewer / utility
Municipal sewer service in developed Palo Alto parcels; verify lateral condition and any point-of-sale sewer compliance requirement before scoping. City of Palo Alto Utilities (CPAU) provides electric, gas, water, sewer, and fiber — a notable difference from most Peninsula cities. Coordinate service upgrades through CPAU early.
Electrical / mechanical / plumbing
Often pulled with the building permit; some jurisdictions require separate sub-permits per trade.
Title 24 compliance
California Energy Commission Climate Zone 4. New single-family homes must comply with the current Title 24 Part 6 envelope, HVAC, hot-water, and rooftop solar-PV requirements.
CALGreen
CALGreen Part 11 mandatory measures (≥65% C&D waste diversion, water-efficient fixtures, indoor-air-quality measures) apply to all new homes. Palo Alto has adopted an all-electric reach code for new construction with limited exceptions; verify current scope at intake.
Plan check process.
Plan check is rigorous on Title 24, the city's all-electric reach code, and the local protected-tree ordinance — heritage oaks frequently constrain siting.
Entitlement & planning review.
Many R-1 rebuilds are ministerial but trigger Individual Review (IR) for second-story projects; historic-district parcels add Historic Resources Board (HRB) review and demolition findings.
Inspections.
City of Palo Alto Planning & Development Services — Building Division schedules inspections through its permit portal; foundation, framing, rough trades, insulation, drywall, and final are the standard hold points for new SFRs in Palo Alto.
Local overlays & constraints.
Palo Alto uses R-1, R-1(7000), R-1(8000), and R-1(10000) sub-districts plus the R-2 and RM districts; Professorville and other historic districts add design-review and demolition-review overlays.
Hillside. Palo Alto Hills parcels are subject to a Site & Design (SD) overlay with grading limits, ridgeline rules, and biology review.
Wildfire / WUI. Foothill and Palo Alto Hills parcels are in CAL FIRE Very-High Fire Hazard Severity Zone — Chapter 7A applies on mapped lots.
Seismic. The San Andreas Fault zone runs along the western hills; CGS Alquist-Priolo zones constrain hillside parcels; portions of the eastern flats are in CGS liquefaction zones.
Common delay drivers.
Risk 1
Heritage-oak survey driving footprint change late
Risk 2
IR opposition triggering second-story redesign
Risk 3
All-electric scope misread leaving gas in late drawings
Prepare before submittal.

- Complete Title 24 energy modeling and confirm CALGreen targets.
- Have a clear utility upgrade plan (sewer lateral, panel, gas) documented.
- Pre-assemble any overlay-specific studies (hillside, coastal, fire, flood).
