Verified Development Fee Calculator

Calculate verified fees

How the calculation works

• Verified amounts only. Every rate comes from a published ZoneFee record that cites the official schedule, and an automated check fails the site build if a calculator rate does not appear in that record or its schedule has expired.
• The schedule's own basis. Fees are applied per dwelling, per room, per lot, per acre, per square foot, per 1,000 square feet, per water meter or as a flat amount, exactly as the schedule states. Size tiers, service areas, meter sizes and providers are applied only after you choose them.
• Unknown is not zero. A fee that depends on an unanswered question, an unsupported size, or a schedule that does not cover the fee date is listed under "Fees not calculated" with the reason. A $0.00 line appears only where the official schedule prints $0.
• Line-by-line arithmetic. Each line is calculated in whole cents and rounded once, half up. Acreage is rounded up only where the schedule says "or portion thereof".
• Not applied. Credits, exemptions, vesting and grandfathering rules, refunds and negotiated agreements are listed for confirmation, never deducted automatically.
• Not a project cost. Permit, plan review, inspection, utility construction, infrastructure and any fee not listed are outside the total.
