State Allocation Board raises the Level 1 school fee cap to $5.38 per sq ft

On January 28, 2026 the State Allocation Board raised the statewide maximum Level 1 developer fee for residential construction from $5.17 to $5.38 per sq ft (+4.06%). School districts collect it on ADUs of 500 sq ft or more, at their own adopted rate up to this cap (higher Level 2/3 fees need extra findings). Where we haven't confirmed a district's rate, we use $5.38 as the upper bound.

Increase the 2026 maximum Level I assessment for development in the amount of 4.06 percent
