School fees: the one exaction with a statutory price ceiling

School facilities fees are the one impact-fee category with a statewide price ceiling. Under the SB 50 framework — Gov. Code §§ 65995–65998, archived with the fee chapters, and Education Code companions — districts levy per-square-foot fees on new residential construction at three levels: Level 1 (the base statutory cap, adjusted every two years by the State Allocation Board), Level 2 (roughly half of school-house costs, available to districts with qualifying needs analyses), and the rarely operative Level 3 (tied to state-bond insolvency).

Payment is deemed full and complete mitigation of school impacts: § 65996 bars cities and counties from denying or conditioning approvals on additional school mitigation — including via CEQA. That preemption is one of the strongest developer protections in the fee stack.

• Level 1: the default per-square-foot cap on assessable residential space, biennially adjusted; commercial/industrial pays a lower schedule.
• Level 2: a district that adopts a compliant School Facilities Needs Analysis and meets eligibility tests may charge its computed share — commonly 2–4× Level 1 in high-growth districts; the analysis must be re-adopted annually.
• Level 3: doubles Level 2 when state new-construction funding is exhausted — historically suspended almost immediately when triggered; treat as tail risk.
• Overlapping districts: elementary + high-school districts split the cap by agreement — the combined charge cannot exceed the applicable level.

• Underwriting watch-outs:
• Verify the district's current resolutions and needs analysis — Level 2 authority lapses if not annually renewed, and stale analyses are protestable.
• Assessable space excludes garages and certain common areas; measure the fee off the statute's definition, not gross building area.

• ADUs under 750 sq ft: exempt from school fees entirely; larger ADUs pay residential rates on their area.
• Senior housing: age-restricted projects qualifying under the statute pay the (much lower) commercial/industrial rate rather than residential.
• Reconstruction and remodel: fees apply to net new assessable space; like-for-like rebuilds after demolition earn square-footage credits — document the demolished area before teardown.
• Mitigation agreements: existing school-mitigation agreements recorded on large master-planned sites can supersede the schedule — check title.

Districts certify payment before the city issues the building permit (the certificate-of-compliance mechanic), so unlike most impact fees deferred by § 66007, school fees are effectively a permit-time cost — put them in the draw schedule accordingly. The Mitigation Fee Act's § 66020 protest procedure and 90-day clock apply; Level 2 fights typically attack the needs analysis.

Because § 65996 makes the fee exclusive, any city-imposed school exaction beyond the statutory fee — dedications, per-unit school payments in development agreements pressed as conditions — is preempted and protestable. Development agreements can still voluntarily include more; know which posture you are negotiating in.
