Residential per-sq-ft fee is on total square footage including covered porches, garages, basements, attics with access and stairways; the calculator's single area input may understate this
'Inspections: Residential $100 / Commercial $150' is listed without saying whether it is per inspection or once per permit, and could add $100 or several hundred dollars to a typical house permit. Stored as conditional additional_fees ('may also apply', outside the total). Confirm with the Plan Commission before publishing
Construction-before-permit penalty is stored as a +50% surcharge for the first offense only (2x and 3x for later offenses described in notes)

Separate electrical, plumbing, mechanical, fire, impact, utility and school fees are usually not included unless they are listed. BuildingPermitCost is not a government permit office, and this is not legal advice.
