What each job was filed at
"Usual" is the middle permit: half were filed for less, half for more. "Middle half of firms" takes every firm with three or more permits in the trade, finds each firm's usual job, and shows the band the middle 50% of firms sit in; it is the number to hold a quote against. A dash (—) in the firms column means fewer than eight firms had three or more permits, so there is no band.
| Job | Usual filed value | Middle half of firms | Permits (share priced) | Usual days to final | Pages |

Demolition has a compare page but no cost page: 79.2% of its 260 permits carry a value. Cincinnati permits stay open a long time: the usual new home took 660 days from issue to final and the usual remodel 340. Those days run to the final inspection, not to the end of the work.
What moves the price in Cincinnati
The home. Each cost page splits firms into thirds by the usual value of the homes they work on (Hamilton County CAGIS parcel market values). Cincinnati's single-family value figure is $201,000.
| Job | Firms on the least expensive third | Firms on the most expensive third |
|---|---|---|
| Retaining wall | $8,200 | $25,000 |
| Home addition | $63,670 | $154,500 |
| HVAC | $4,500 | $8,074 |
| Garage & shed | $20,000 | $34,000 |
| Remodel & alteration | $20,000 | $28,000 |
| Plumbing | $3,500 | $4,500 |
Figures from each cost page, data of 16 October 2026. Retaining walls triple and additions more than double with home value; HVAC nearly doubles. Plumbing and remodels move far less.
The firm. In remodels the ten busiest firms usually file $9,009 a permit, while the 819 firms with fewer than ten permits usually file $22,500 (Cincinnati remodel cost page). In new homes the ten busiest builders usually file $118,877, against $350,000 for 115 smaller builders (Cincinnati new-home cost page).
The season. HVAC permits peak in October (index 140, where 100 is an average month) and are fewest in September (78). We have no prices by month.
What a Cincinnati permit costs
From the Department of Buildings and Inspections fee schedule, effective 1 July 2026 (read 23 October 2026). RCO is a one- to three-family home under the Residential Code of Ohio:
| Permit | Fee |
|---|---|
| Building, without plans | $106 at $2,000 of project valuation, $336 at $10,000, $550 at $20,000, $1,065 at $50,000; over $50,000, $1,065 + $11.59 × (valuation / $1,000) |
| HVAC, RCO without plans | $102 at $2,000 of valuation, $369 at $8,000, $450 at $10,000 |
| HVAC replacement, RCO | $118 for the first unit + $48 for each additional unit |
| Plumbing | $68 for one replaced fixture, $97 for one new fixture, $33 for each additional fixture above 50 |
| Wrecking (demolition) | $108 for the first 1,000 sq. ft. of building, $59 for each additional 1,000 sq. ft. |
Added on top: a 1% State surcharge on RCO permits, a 3% technology surcharge, a 5% planning surcharge on construction, plumbing and HVAC permits, a 1% training surcharge, and a $49 processing fee on RCO applications (not charged on plumbing and HVAC repair or replacement without plans). Work started without a permit pays an investigation fee equal to the permit fee, up to $1,695.
Filed value is not the price
- The fee rides on it. Building and HVAC fees climb with valuation, about $20 to $40 per extra $1,000 in the lower bands, a small reason not to round up.
- Replacements don't. An HVAC replacement in a home is charged per unit, so those values are less likely to be trimmed.
- The lot. New-home values are construction only.
Check a quote in five minutes
- Find your job in the table and open its cost page.
- Put your quote against the "middle half of firms" band. Inside it is normal here; above it, ask what the extra covers.
- Open compare firms, find the contractor, and read its usual filed value, permit count and finished share.
- Put "permit closed with a final inspection" in the contract; in Cincinnati that step is the slow one.

How we know this
Every row is a permit type with a cost page: the City of Cincinnati issued at least 100 priced permits of it in the window 2023-10 to 2026-09, making up at least 80% of the type. Usual = median of the permits that carry a value; middle half of firms = 25th to 75th percentile of the usual value of firms with three or more permits in the trade (shown when at least eight firms qualify); days = median from permit issue to final inspection. Home-value thirds and busiest-firm figures are copied from each job's cost page and dated. Fees are quoted from the City's 2026 fee schedule linked under Sources.
Numbers come from City of Cincinnati building permits (residential, Residential Code of Ohio), data through October 16, 2026. Nobody paid to be on this page and nobody can.
