A roof replacement on this row is valuation-based, and a permit is required. The official fee band is $198.21 low, $238.61 typical, and $339.61 high.
The official typical project value is $12,000. Listed assumed valuations are $8,000 low, $12,000 typical, and $22,000 high.
The city building permit is a $43.64 minimum; above $2,000 it is $43.64 + 1% of cost over $2,000. That 1% over $2,000 is about $1 per $100 of job cost above $2,000.
The Ohio 1% residential surcharge applies on the city building permit line only, for 1-2-3 family work. The zoning certificate is 0.2% of project value, with a $93.53 minimum and a $10,000 maximum; there is no state surcharge on zoning.
Job valuation, not roof area, drives the building permit line. Residential CUO $125.45 is a certificate of occupancy and is not added to these alteration totals.
Walk the typical first. At $12,000 the city building permit is $43.64 + 1% x $10,000 = $143.64.
The Ohio 1% on that line is $1.44. Zoning 0.2% x $12,000 is $24, below the $93.53 minimum, so zoning is $93.53. $143.64 + $1.44 + $93.53 = $238.61, so the typical fee is $238.61.
- Low $8,000: city $43.64 + $60 = $103.64; Ohio $1.04; zoning $93.53 (minimum); total $198.21.
- High $22,000: city $43.64 + $200 = $243.64; Ohio $2.44; zoning 0.2% x $22,000 = $44, still the $93.53 minimum; total $339.61.
The $339.61 high is not added on top of the $238.61 typical. The $93.53 minimum applies at all three points; 0.2% would only exceed $93.53 above $46,765 of value ($93.53 / 0.002 = $46,765).
The formula was revised 4/2026. Documented 1,000 / 1,500 / 1,800 sf of roof surface does not change those fees.
The three listed lines at the $12,000 typical are the city building permit at $143.64, the Ohio 1% residential surcharge at $1.44, and the zoning certificate at $93.53. This note does not invent a fee beyond the official $198.21, $238.61, and $339.61 totals.
