Permit fee estimate

estimate_permit_fee

Read-onlyIdempotent

Estimate the permit fee for a residential project based on jurisdiction, project type, and project valuation. Returns numeric breakdown when the authoritative rule has fee inputs, or qualitative feeNotes (with source URL) when the city publishes fees only as PDFs/spreadsheets. Never fabricates dollar amounts.
