Palo Alto Individual Review (IR) explained: when it applies, the guidelines, timeline and how to pass (2026)

What Individual Review is, and when it applies

Individual Review (IR) has been part of Palo Alto's R-1 zoning since 2001 ^[5], but the trigger changed in 2025. R-1 homes must now meet the City Council's objective standards for two-story development, and an applicant who wants to deviate from them may apply for IR instead ^[3]. Those standards took effect February 14, 2025 ^[7]. IR therefore applies to construction that does not comply with them: a new two-story house, a new second story, or expanding an existing second story by more than 150 sq ft, counting all second-story additions on the site since November 19, 2001 ^[2].

In other words, IR is now the flexible route: a design that meets every objective standard skips it, and one that does not is judged against the 2005 Single-Family Individual Review Guidelines ^[2],[5]. The code says IR is meant only to mitigate a second story's effects on neighbors, not to prohibit a second story zoning allows ^[2], and the guidelines say IR does not prescribe architectural styles ^[5].

The five IR guidelines in plain language

The guidelines contain five topics, each with an approval criterion that must be met, followed by illustrated “key points” ^[5]. The code bars the director, and the City Council on appeal, from approving an IR application unless it is consistent with the guidelines ^[2]. Applicants fill in a Key Points checklist explaining how the project meets each guideline ^[6].

• 1. Basic site planning (driveway, garage, house). Place the house, garage and driveway to follow the street's existing pattern of footprints, setbacks and yards, and keep the garage and driveway visually secondary to the house, landscaping and front entry. Key points: minimize paving, set back or narrow the garage, avoid a compact box footprint among sprawling neighbors, and pull the upper floor back next to small or one-story homes ^[5],[6].
• 2. Neighborhood compatibility for height, mass and scale. A new house or upper addition must be consistent with the neighborhood's height and bulk, with special attention to the homes next door. The guidelines warn that meeting this may require a house to be substantially lower than the 30-foot R-1 height limit ^[5]. Key points: put more floor area downstairs, avoid raised first floors, tall walls and boxy forms, avoid sharp eave-height contrasts, and tuck floor area into the roof ^[5],[6].
• 3. Architectural form, massing and rooflines. Massing should reduce visual bulk and express a clear style; roofs should organize primary and secondary volumes, with the garage and entry subordinate. Second-story additions must look integrated, not like a “layer cake.” Key points: test roof and massing early, use a few simple masses, and avoid cluttered gables and dormers ^[5],[6].
• 4. Street-facing facades and entries. Publicly visible facades need a clear, cohesive composition with a focal point and supporting materials and details; the entry should fit the neighborhood pattern; the garage door should match the home's style. Key points: design visible side and corner elevations with equal care, avoid monumental entries, follow a prevailing porch pattern, and keep garage doors modest ^[5],[6].
• 5. Second-story windows and decks for privacy. The size, placement and orientation of upper windows and decks must limit direct sight lines into neighbors' windows and patios at the rear and sides. The guidelines note that complete privacy is not a realistic expectation, but designs should minimize intrusion on existing privacy such as the main patio ^[5]. Key points: map neighbors' windows and yards first, then use obscure glazing, screening plants, screens or higher sills where needed; upper decks are allowed only with minimal privacy loss ^[5],[6].

Height and daylight plane are zoning limits that apply on either path, and IR does not relax them. In R-1 the maximum height is 30 feet to the roof peak, or 33 feet for roofs pitched 12:12 or steeper; the side daylight plane starts 10 feet up at the interior side lot line and rises at 45 degrees; the rear daylight plane starts 16 feet up at the rear setback line at 60 degrees ^[3]. The IR guideline checklist adds that next to existing one-story homes, extra techniques may be needed, such as more floor area downstairs and lower plate heights on all floors, especially in floodplain areas ^[6].

IR or the objective standards: what you trade

The objective standards turn many IR ideas into fixed numbers. Among them: second floor no larger than 35% of allowable floor area or 400 sq ft, whichever is larger; roof height of 27, 25 or 22 feet depending on pitch; street-facing eaves within 18 inches of the neighbors'; one street-facing balcony of up to 40 sq ft; upper windows within 20 feet of a side or rear lot line screened, obscured or with a 5-foot sill; one screening tree per 25 feet of interior lot line; and, next to a one-story home, a side daylight plane starting at 8 feet instead of 10 ^[7]. IR lets you meet the same goals with judgment instead of fixed numbers, at the cost of a noticed, discretionary process ^[2],[4].

The IR process and timeline

Only adjacent neighbors can request a hearing or appeal, even though notices go out to a wider radius ^[10]. In the code, “adjacent” means lots sharing a boundary, the lot directly across the street, and the next lots diagonally across the street ^[4]. You may apply for a building permit during the 14-day hearing-request window at your own risk, and the permit plans must substantially conform to the IR approval ^[9]. An approval expires after 12 months if construction has not started, with one director extension of up to 12 more months available ^[4].

Fees under the schedule effective August 17, 2026: $1,193 for the preliminary meeting; $16,575 for a new two-story home or new second story; $8,507 for a second-story expansion over 150 sq ft; $4,304 for minor revisions to an approved project; $601 for Urban Forestry tree review; $1,293 for historic review of an IR application; and $646 for an appeal or request for hearing before the Council ^[12]. These are city planning fees only; building permit and impact fees are separate ^[12].

Pre-submittal checklist: what we do before a first IR submittal

• Decide the path first. Run the design against every objective two-story standard; if it already complies, IR does not apply ^[2],[7]. If it does not, list each deviation so the IR narrative can explain it.
• Draw the streetscape elevation with one home on each side, to scale, before finalizing the massing. It is required, and it is where Guideline 2 is judged ^[5],[8].
• Prepare the neighborhood privacy diagram: your second-floor plan plus neighbors' windows, patios and major vegetation within 25 feet of the lot lines ^[8]. Fix window placement against it (Guideline 5) ^[5].
• Label second-floor sill heights, window operation and any obscure glazing on the elevations ^[8]. If you propose an upper deck or sills below 5 feet, include panoramic photos taken from that height and location ^[8].
• If privacy screening trees are needed, specify species and plant at least 24-inch box, 8 feet tall ^[8].
• Have an ISA-certified arborist complete the tree protection sheet; development inside the protection zone of a protected tree needs a Tree Protection Report ^[8].
• In a Special Flood Hazard Area, talk to Public Works before submitting and show the base flood elevation ^[8].
• Book the preliminary meeting with early plans rather than finished ones; the city describes it as early, non-binding advice ^[9],[11].
• Talk to the adjacent neighbors before you submit. The code and checklist both encourage it ^[2],[8], and only adjacent neighbors can later request a hearing or appeal ^[10].

Common reasons a design gets sent back

The guidelines illustrate each topic with designs that do not meet it. The recurring problems are a stacked, square floor plan that reads as a box; a garage and driveway as prominent as the house; eaves and ridgelines well above the neighbors' with tall wall planes; a second story that sits on the first like a separate layer; too many gables and dormers; an over-scaled or monumental entry; and side-facing bay windows, large bedroom windows or a low-railed deck looking into the neighbors' bedrooms and patio ^[5]. On process, partial resubmittals by email may not be accepted, and flood-zone projects must be discussed with Public Works before submittal ^[8],[9].
