New construction · Palo Alto
What permits are needed for new construction in Palo Alto?
New construction in Palo Alto requires building, electrical, plumbing, and mechanical permits through City of Palo Alto Planning & Development Services — Building Division, plus any entitlements (zoning / planning review) triggered by the project. 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.
What changes the answer in Palo Alto.
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. 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.
- 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.
- Buildable envelope is shaped by lot-size sub-district FAR, side-yard daylight planes, and a 30-foot height limit; second stories trigger IR noticing and sometimes story poles.
- 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.
- Municipal sewer service in developed Palo Alto parcels; verify lateral condition and any point-of-sale sewer compliance requirement before scoping.
