Size in this model is roof surface. One roofing square is 100 sq ft of roof surface, and the typical job is 16 squares (1,600 sq ft of roof surface, not floor area). In this model, 2,000 sq ft means roof surface (20 squares). It is separate from the floor area of a home, and the model has no floor-area input. The cost-by-size table has no 2,000 sq ft row; its rows are 10 squares (1,000 sq ft of roof surface), 16 squares (1,600 sq ft of roof surface, not floor area), and 18 squares (1,800 sq ft of roof surface). Read as roof surface, 2,000 sq ft is 20 squares. The calculator already scales job cost by squares divided by 16, and 20 is inside the allowed range of 8 to 60, so these figures are that same scale, not a guess between table rows. At 20 squares in Dayton, OH the all-in is $7,531 low, $12,176 typical, and $57,495 high. Those all-in figures add the model's rounded permit for the bands on this row. The official fees are $198.21, $238.61, and $339.61. The model rounds each to the nearest dollar before adding it, so the all-in uses $198 on the low, $239 on the typical, and $340 on the high.

The city building permit is $43.64 plus 1% of cost over $2,000, plus the Ohio 1% residential surcharge on that building line, plus the zoning certificate at the $93.53 minimum on these rows. It is not rescaled when the roof size changes, and it is not a new fee for 20 squares. Documented 1,000 / 1,500 / 1,800 sf of roof surface does not change those fees.

Why are the low, typical, and high roof permit fees $198.21, $238.61, and $339.61 in Dayton?

The low, typical, and high fees are three applications of the same valuation formula. The city building permit is a $43.64 minimum; above $2,000 it is $43.64 plus 1% of cost over $2,000 (1% over $2,000, about $1 per $100 of job cost above $2,000). The Ohio 1% residential surcharge is 1% of that city building permit line only. The zoning certificate is 0.2% of project value, with a $93.53 minimum. Walk the typical valuation first. At $12,000: city $43.64 + 1% x $10,000 = $143.64; Ohio 1% 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. 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 $93.53 minimum applies at all three points. The $339.61 high is not added on top of the $238.61 typical. Residential CUO $125.45 is not added. The model rounds those listed fees to $198, $239, and $340 before adding them to the all-in estimate.

Does roof size change the Dayton roof permit fee?

No. Roof size does not change the City of Dayton permit fee. Job valuation drives the building permit line: $43.64 plus 1% of cost over $2,000, then the Ohio 1% residential surcharge on that building line, then the zoning certificate at the $93.53 minimum on these rows. Documented 1,000 / 1,500 / 1,800 sf of roof surface does not change those fees. The official fees stay $198.21, $238.61, and $339.61 at the assumed valuations of $8,000, $12,000, and $22,000. The cost-by-size table adds those listed fees rounded to $198, $239, and $340. It does not compute a new permit for 16 squares or for 20 squares.

What is the zoning certificate on a Dayton roof permit, and why does it stay $93.53?

The zoning certificate is 0.2% of project value, with a $93.53 minimum and a $10,000 maximum, and it is charged on all building permits. At the official valuations, 0.2% of $8,000 is $16, 0.2% of $12,000 is $24, and 0.2% of $22,000 is $44. Each of those is below the $93.53 minimum, so the zoning line stays $93.53 at the low, typical, and high. 0.2% would only exceed $93.53 above $46,765 of value ($93.53 / 0.002 = $46,765). There is no state surcharge on zoning. The $10,000 maximum does not bind at these valuations.

Is the Ohio 1% surcharge on the zoning certificate line in Dayton?

No. The Ohio 1% residential surcharge is on the city building permit line only. At the typical $12,000 valuation that surcharge is $1.44, which is 1% of the $143.64 city building permit. The zoning certificate is $93.53 at each listed valuation; the zoning line has no state surcharge. That $93.53 is not multiplied by 1%.
