Portola Valley homeowners can generally build ADUs up to 1,200 square feet, or 50% of the existing primary dwelling's living area, whichever is less, for detached units. For attached ADUs, the maximum size is typically 850 square feet for a one-bedroom unit or 1,000 square feet for a two-bedroom unit. Specific setback requirements, often 4 feet from side and rear property lines, also apply and can influence the final footprint, so verifying your specific property's allowances is a critical first step.
Building an ADU in Portola Valley typically takes 8 to 12 months from the start of construction to final occupancy, assuming permits are already secured. This timeframe includes site preparation, foundation work, framing, rough-ins for utilities, finishes, and final inspections. The permitting phase, which precedes construction, can add an additional 3 to 6 months depending on the complexity of the design and the town's review process, particularly if design review is required for properties in specific overlay zones like the Portola Valley Ranch area.
Obtaining ADU permits in Portola Valley involves submitting architectural plans, structural engineering documents, and site plans to the Town's Planning Department for review. This typically includes an initial planning review for zoning compliance, followed by a building plan check for structural and safety codes. Depending on your property's location, a design review may also be necessary, especially for properties visible from public roads or within specific architectural guidelines. Once all reviews are complete and comments addressed, the building permits are issued, allowing construction to begin.
