Rockford ADU Permit Fees & Cost Calculator
Rockford appears to have a city fee schedule that governs residential building permits and related development charges, but the official fee documents found do not clearly isolate an ADU-specific permit fee. Current public materials point to valuation-based building permit and inspection fees, plus separate utility and land-use charges that may apply depending on the project scope and hookups.

Fee overview
The official Rockford documents provided were partially excerpted and do not expose the full current fee table, so exact ADU total costs cannot be confirmed from these sources alone.
No school district fee source was identified in the provided results.
Some third-party sources mention Rockford permit timing or fee ranges, but those were not relied on because they are not official city sources and did not provide exact ADU fee schedules.
Rockford does not appear to publish a clearly labeled ADU-specific fee schedule in the provided sources, so related permit and entitlement charges are being reported from general residential and land-use fee schedules.
An ADU in Rockford may require standard building permit, inspection, and possibly zoning or utility-related fees depending on the site and approval path.
The quoted utility charge may not be a one-time connection fee; it should be verified before use in cost estimates.
