About each permit

Commercial Building Permit (Schedule 1, by floor area)

This is the largest single county cost in a Montgomery County build-out, and it is calculated from floor area rather than from construction value — a point worth fixing before any budget is drawn, since a valuation-based estimate will not resemble the real figure. The band table above is the 'New Fee' column of the schedule the Board of County Commissioners adopted at its public meeting of 28 October 2025, after public hearings on 21 and 28 October, effective 1 January 2026; the county's news release of 17 November 2025 prints the first five bands ($500, $1,200, $2,200, $3,200, $4,800) in the same terms, and the release of 31 December 2025 calls it 'the first adjustment since 2017.' The PDF's page header still reads PROPOSED, which is a leftover from drafting rather than a description of the document's status. Zoning comes first and comes from somewhere else: the FAQ states that 'Zoning permits must be obtained for all new work and most changes of use of buildings. They are obtained from the township, city, or village in which the building is located. They should be obtained before applying for the building permit, but in specific instances, exceptions may be made.' Submissions go through the county's Accela portal. The fee applies only in the jurisdictions on Building Regulations' jurisdictional chart — all nine townships, the cities of Brookville, Huber Heights, Riverside, Trotwood and Union (Union for commercial work only), the villages of Farmersville, New Lebanon and Phillipsburg, and WPAFB-PageManor; the FAQ records that 'Effective January 10, 2023, Montgomery County will no longer perform building services for the City of Clayton.'

Type I Exhaust Hood / Paint Spray Booth Permit (mechanical)

Line M.2 of the county's building fee schedule charges $400 per hood, with three inspections, for Type I exhaust hoods and paint spray booths — the schedule describes it as being 'For hoods that require fire suppression,' with a hood defined as 'that served by a single exhaust fan.' It is the mechanical permit for the hood itself, and it stacks with the $250 suppression system permit on line B.6 rather than replacing it, so a restaurant putting in one suppressed cooking hood pays $650 between the two, and a body shop's spray booth is treated identically. A kitchen with two exhaust fans pays each line twice. A hood that does not require fire suppression is a Type II hood, priced at $250 on line M.3 and listed separately for this jurisdiction. All three lines come from the schedule the Board of County Commissioners adopted at its public meeting of 28 October 2025, after public hearings on 21 and 28 October 2025, effective 1 January 2026, as the county's own news releases of 17 November and 31 December 2025 state; the published PDF's page header still reads PROPOSED from the drafting stage. The permit applies in the jurisdictions the county serves — all nine townships, the cities of Brookville, Huber Heights, Riverside, Trotwood and Union (commercial work only), the villages of Farmersville, New Lebanon and Phillipsburg, and WPAFB-PageManor.

Sign Permit (freestanding or wall)

Putting up a freestanding or wall sign is a $300 county permit covering one sign and two inspections, with each additional sign at the same address charged at $25 — so a shop with a fascia sign, a pylon sign and a door sign pays $350 rather than three full permits. The schedule states that the 'Inspection includes electric,' so an illuminated sign does not need a separate electrical permit for the sign itself. Two other approvals sit alongside this one and neither is replaced by it: the township, city or village issues the zoning permit, and its sign ordinance governs size, height, placement and illumination — the county's FAQ states that 'Zoning permits must be obtained for all new work and most changes of use of buildings. They are obtained from the township, city, or village in which the building is located.' The fee is from the building schedule adopted at the county's public meeting of 28 October 2025, after hearings on 21 and 28 October 2025, effective 1 January 2026; the published PDF's header still reads PROPOSED from the drafting stage. It applies only in the jurisdictions the county serves: all nine townships, the cities of Brookville, Huber Heights, Riverside, Trotwood and Union (commercial work only), the villages of Farmersville, New Lebanon and Phillipsburg, and WPAFB-PageManor. A sign in Dayton, Kettering, Centerville or another self-administering city is permitted by that city instead.

Commercial Temporary Certificate of Occupancy

A business that has to open before its build-out is finished asks for a temporary certificate of occupancy, which the county's fee schedule prices at $400 and describes as being for use 'When work is not complete, but following final inspection, CBO deems building safe to occupy.' It is discretionary and it is not cheap relative to the $325 standard certificate, so it is worth treating as a contingency line in a fit-out budget rather than a plan. The permanent certificate still has to follow: the FAQ states that 'Each finished building, tenant space, or dwelling unit requires a Certificate of Occupancy,' and that certificates are 'issued for a specific use of a building or space, not a specific tenant, and do not expire if the use does not change.' The schedule also prices an additional certificate of occupancy at $100, limited to multi-family buildings. The fee comes from the schedule adopted at the county's public meeting of 28 October 2025 after public hearings on 21 and 28 October 2025, effective 1 January 2026; the published PDF's header still reads PROPOSED from drafting. It applies in the jurisdictions on the county's chart: all nine townships, the cities of Brookville, Huber Heights, Riverside, Trotwood and Union (commercial only), the villages of Farmersville, New Lebanon and Phillipsburg, and WPAFB-PageManor.

Commercial Certificate of Occupancy

Montgomery County Building Regulations states in its FAQ that 'Each finished building, tenant space, or dwelling unit requires a Certificate of Occupancy,' and its $325 line covers the stand-alone case: taking over an existing space whose approved use is not changing. The FAQ explains when a new certificate is unnecessary — 'To use a building in the same manner as previously approved, such as a dress shop occupying a former men's clothing store, and the former use had been legally approved, no new Certificate of Occupancy is needed. C.O.'s are issued for a specific use of a building or space, not a specific tenant, and do not expire if the use does not change' — so a tenant replacing a like-for-like tenant may inherit the existing certificate, while a cafe moving into a former retail unit is a change of use and takes the full permit route. A zoning certificate from the township, city or village is a different document and does not substitute: the FAQ states that 'A zoning Certificate of Occupancy only signifies compliance with zoning ordinances for land use approval. It does not take the place of Montgomery County's Certificate of Occupancy for building use approval.' The amount comes from the fee schedule the county adopted at its public meeting of 28 October 2025, after hearings on 21 and 28 October 2025, effective 1 January 2026, as the county's own news releases of 17 November and 31 December 2025 state; the PDF's page header still carries the word PROPOSED from the drafting stage. This fee applies only where the county does the building enforcement — all nine townships, the cities of Brookville, Huber Heights, Riverside, Trotwood and Union (Union commercial work only), the villages of Farmersville, New Lebanon and Phillipsburg, and WPAFB-PageManor; Clayton left the county's building services on 10 January 2023 per the same FAQ.

Commercial Sprinkler, Alarm, Mechanical and Electrical Permit (Schedule 1)

Sprinkler, fire alarm, mechanical and electrical work on a commercial project is priced on its own set of area bands, separate from and in addition to the general construction permit, so a 5,000 square foot restaurant build-out is a $2,200 construction permit plus $600 on this line before any of the flat-fee items. The bands come from the same schedule the county adopted on 28 October 2025 after public hearings on 21 and 28 October, effective 1 January 2026, whose page header still reads PROPOSED from the drafting stage. These bands cover the systems work embedded in a build-out; discrete equipment jobs are priced as flat fees elsewhere on the schedule — a commercial furnace, air-conditioning or water heater replacement of the same size in the same location is $225 per unit including mechanical, electrical and up to ten feet of gas piping, commercial building service piping is $250, a commercial gas piping system with plan review is $250, a commercial reconnect or temporary pole is $175 per address including the release to the utility, and adding a meter is $50. The work must be in a jurisdiction the county serves: all nine townships, the cities of Brookville, Huber Heights, Riverside, Trotwood and Union (Union for commercial work only), the villages of Farmersville, New Lebanon and Phillipsburg, and WPAFB-PageManor. Elsewhere in the county the city or village runs its own building department and its own fees.

Hood Suppression System Permit (kitchen hood, paint booth)

Installing the fire suppression system over a commercial kitchen hood or a paint spray booth is its own $250 permit line on the county's building fee schedule, charged per hood, where the schedule defines a hood as 'that served by a single exhaust fan.' A kitchen with two exhaust fans therefore pays twice. This is only half the cost of a suppressed hood in Montgomery County: the mechanical side of the same installation is charged separately at $400 per hood under line M.2 for Type I exhaust hoods and paint spray booths, listed separately for this jurisdiction, so a single suppressed kitchen hood draws $650 across the two lines before the general construction and mechanical band fees. A body shop's spray booth falls on exactly the same pair of lines. The amount is from the fee schedule adopted at the county's public meeting of 28 October 2025, after public hearings on 21 and 28 October 2025, and effective 1 January 2026, as the county's news releases of 17 November and 31 December 2025 state; the PDF's header still carries the word PROPOSED from drafting. The permit applies only where the county does the building enforcement: all nine townships, the cities of Brookville, Huber Heights, Riverside, Trotwood and Union (Union for commercial work only), the villages of Farmersville, New Lebanon and Phillipsburg, and WPAFB-PageManor.

Type II Exhaust Hood Permit (mechanical)

A Type II exhaust hood — the kind over dishwashers, steam tables, ovens and other equipment producing heat, steam and odour rather than grease-laden vapour — is permitted at $250 per hood with one inspection under line M.3, which the county's schedule describes as being 'For hoods that do not require fire suppression.' This is the cheaper of the two mechanical hood lines and the one a coffee shop, bakery or deli counter is most likely to meet, since it carries no suppression system and no second permit: a Type I hood over cooking equipment instead draws $400 on line M.2 plus $250 for the suppression system on line B.6. As with the other hood lines, the schedule prices per hood, defined as that served by a single exhaust fan. The figures come from the fee schedule adopted at the county's public meeting of 28 October 2025, following public hearings on 21 and 28 October 2025, and in effect since 1 January 2026, as the county's own news releases of 17 November and 31 December 2025 state; the PDF still carries a PROPOSED header from drafting. Like every other county building fee, it applies only in the jurisdictions on the county's jurisdictional chart: all nine townships, the cities of Brookville, Huber Heights, Riverside, Trotwood and Union (commercial only), the villages of Farmersville, New Lebanon and Phillipsburg, and WPAFB-PageManor.

Commercial Pool / Spa Building Permit

Building a commercial pool or spa at a gym, club or hotel in a county-served jurisdiction is a single $750 permit that the schedule says 'Includes up to 5 inspections of building, electric, and/or mechanical,' so the electrical and mechanical work for the pool is bundled rather than billed on the Schedule 1 systems bands. This is the construction side only. Operating the finished pool is a separate annual license from Public Health at $655.00 for the first unit and $430.00 for each additional unit, and before either of those the Ohio Department of Health does its own plan-review approval — Public Health's page states that 'The Ohio Department of Health must approve the swimming pool to operate through a plan review process. Once approved, the operator must submit an application and fee to Public Health.' A fitness studio putting in a whirlpool or splash pad is on the same three-step path as one putting in a lap pool. The building fee comes from the schedule adopted at the county's public meeting of 28 October 2025 after hearings on 21 and 28 October 2025, effective 1 January 2026, whose published PDF still carries a PROPOSED header from drafting. It applies only in the jurisdictions on the county's chart: all nine townships, the cities of Brookville, Huber Heights, Riverside, Trotwood and Union (commercial only), the villages of Farmersville, New Lebanon and Phillipsburg, and WPAFB-PageManor.

Floodplain Compliance Review

Montgomery County Building Regulations administers floodplain compliance for the jurisdictions it serves, and charges $150 when that review is the only thing being asked for — the schedule states there is 'No charge if part of a building permit application,' so a project already taking out a county building permit gets the floodplain review folded into it at no extra cost. The stand-alone fee is the one a business meets when it needs a floodplain determination for a lender, an insurer or a property purchase without any construction attached, or when a use changes without building work. The Great Miami and Stillwater river corridors put substantial commercial frontage in Butler, Harrison, Miami, Jefferson and Washington townships within mapped flood hazard areas, which is why this line matters more here than the small amount suggests. The fee is from the schedule adopted at the county's public meeting of 28 October 2025 following public hearings on 21 and 28 October 2025, effective 1 January 2026, as the county's news releases of 17 November and 31 December 2025 state; the published PDF's header still reads PROPOSED from drafting. The review covers the jurisdictions on the county's chart: all nine townships, the cities of Brookville, Huber Heights, Riverside, Trotwood and Union (commercial only), the villages of Farmersville, New Lebanon and Phillipsburg, and WPAFB-PageManor.

Commercial Demolition Permit

Taking a commercial building down in a county-served jurisdiction is a $350 permit with two inspections, and the schedule scopes it to complete removal including slabs, foundations and footings — a partial demolition inside a building being remodelled is part of the alteration permit instead. Demolition has a second, separate obligation that is easy to miss and expensive to miss: RAPCA takes asbestos and demolition notifications for Montgomery County and charges $75 for a demolition-only notification, rising to $200 or $350 where larger quantities of regulated asbestos-containing material are involved, under the schedule it publishes for this county. Budget both, and file the notification on RAPCA's timetable rather than the county's. The building fee is from the schedule adopted at the county's public meeting of 28 October 2025 after public hearings on 21 and 28 October 2025, effective 1 January 2026; the published PDF's page header still reads PROPOSED from the drafting stage. It applies only where the county does the building enforcement: all nine townships, the cities of Brookville, Huber Heights, Riverside, Trotwood and Union (commercial work only), the villages of Farmersville, New Lebanon and Phillipsburg, and WPAFB-PageManor.

Temporary Tent or Structure Permit

A restaurant putting up a seasonal dining tent, a retailer running a sidewalk sale under cover, or an event operator setting up a marquee in a county-served jurisdiction takes this $225 permit, with each additional tent at the same address charged at $25. It is the building-side approval for the structure itself; a food vendor working under the tent still needs the temporary food license from Public Health at $60.00 per event, filed ten days ahead, and the township, city or village still controls the zoning and any special-event permission — Public Health's own advice to operators is to 'Check with event coordinators, city/township officials, property owners, and/or zoning to ensure all permits and proper permission are obtained.' The amount comes from the county building fee schedule adopted at the public meeting of 28 October 2025, after public hearings on 21 and 28 October 2025, and effective 1 January 2026, as the county's news releases of 17 November and 31 December 2025 state; the published PDF's header still carries the word PROPOSED from drafting. The permit applies in the jurisdictions on the county's chart: all nine townships, the cities of Brookville, Huber Heights, Riverside, Trotwood and Union (commercial only), the villages of Farmersville, New Lebanon and Phillipsburg, and WPAFB-PageManor.

Commercial Footing and Foundation Permit

A contractor who wants to start footings and foundations while the full building plans are still in review takes this $500 permit, which carries three inspections and, as the schedule states, 'Does not include slabs.' It is an early-start permit rather than a substitute for the main construction permit: the Schedule 1 area-banded commercial building permit still applies to the building itself, so a 6,000 square foot new build is $500 here plus $2,200 on Schedule 1 plus $600 on the sprinkler, alarm, mechanical and electrical band. The figure comes from the fee schedule the county adopted at its public meeting of 28 October 2025, after public hearings on 21 and 28 October 2025, effective 1 January 2026, as its own news releases of 17 November and 31 December 2025 state; the published PDF's page header still reads PROPOSED from the drafting stage. As with every county building line, it reaches only the jurisdictions on the county's jurisdictional chart — all nine townships, the cities of Brookville, Huber Heights, Riverside, Trotwood and Union (commercial work only), the villages of Farmersville, New Lebanon and Phillipsburg, and WPAFB-PageManor — and the county's FAQ records that 'Effective January 10, 2023, Montgomery County will no longer perform building services for the City of Clayton.'

Additional, Re-inspection, Missed and After-Hours Inspection Fees

Every county permit line includes a stated number of inspections — three for a small commercial project, eleven for a large one, one for a hood — and anything beyond that count is charged. The rates are flat: $125 for an additional general construction, mechanical or electrical inspection, each covering roughly thirty minutes; $125 for a re-inspection after a failure or a lock-out; $300 where work has been completed without a required inspection, which the schedule describes as being 'Invoked when work is completed without required inspection'; and $500 for an after-hours visit covering up to two hours including drive time, with more time at $125 per half hour. For a fit-out running to a deadline these add up quickly, and the missed-inspection charge in particular is the expensive way to discover that a stage was covered up too early. The rates are from the fee schedule adopted at the county's public meeting of 28 October 2025, following public hearings on 21 and 28 October 2025 and effective 1 January 2026, as the county's news releases of 17 November and 31 December 2025 state; the published PDF's page header still reads PROPOSED from the drafting stage. They apply in the jurisdictions on the county's chart: all nine townships, the cities of Brookville, Huber Heights, Riverside, Trotwood and Union (commercial only), the villages of Farmersville, New Lebanon and Phillipsburg, and WPAFB-PageManor.

Inspection Cancellation Fee

Since 1 July 2026 the county charges $125 for an inspection that is not cancelled in time. The Building Regulations landing page states the rule precisely: 'Effective July 1, 2026, a $125 fee will apply to all inspections canceled after 2:00 p.m. on the day prior to the scheduled inspection date,' and the fee schedule's line A.15 repeats it as a fee assessed 'for any inspection not cancelled by 2pm the business day before the scheduled inspection.' For a contractor juggling trades across several sites this is a real operating cost, and the cut-off is early enough that a job slipping on the morning of the inspection is already too late to cancel free of charge. It sits alongside the $125 re-inspection and lock-out charge and the $300 missed-inspection charge on the same schedule, all three of which are triggered by scheduling rather than by the quality of the work. The cancellation line is part of the fee schedule adopted at the county's public meeting of 28 October 2025, whose other lines took effect on 1 January 2026. It applies in the jurisdictions on the county's jurisdictional chart: all nine townships, the cities of Brookville, Huber Heights, Riverside, Trotwood and Union (commercial only), the villages of Farmersville, New Lebanon and Phillipsburg, and WPAFB-PageManor.

Work Without a Permit Penalty

Starting work before the permit is issued doubles the permit fee, with a floor of $600 and a ceiling of $6,000: the schedule's line A.14 states 'Double fee penalty, minimum $600, up to a max $6,000.' On a small tenant fit-out the floor is what bites, since a $500 permit becomes $1,100 in total, and on a large build the doubling runs to the cap. Two related charges make the same point from a different direction: a missed inspection, 'Invoked when work is completed without required inspection,' is $300, and renewing a permit that expired less than a year ago is $100 plus $125 per inspection. The county also charges $125 for a damage assessment or violation visit in business hours and $300 after hours. The schedule these come from was adopted at the county's public meeting of 28 October 2025, after public hearings on 21 and 28 October 2025, and took effect on 1 January 2026, as the county's own news releases of 17 November and 31 December 2025 state; the published PDF's page header still carries the word PROPOSED from drafting. The penalty applies in the jurisdictions the county serves: all nine townships, the cities of Brookville, Huber Heights, Riverside, Trotwood and Union (commercial work only), the villages of Farmersville, New Lebanon and Phillipsburg, and WPAFB-PageManor.

Commercial Deficient Submittal and Major Revision Review

Plan review in Montgomery County is not a single flat cost: an incomplete submittal or a minor change is $200 including the re-reviews that follow a hold response, and a major revision is charged at half the cost of the original permit. On a 20,000 square foot project whose Schedule 1 permit is $6,600, a major redesign therefore adds $3,300 — enough that a design change late in review is worth pricing before it is submitted. The $200 minor-change line is the one most fit-outs meet, typically after a first submission missing equipment schedules or a sealed drawing. The half-cost major-revision line is carried over unchanged from the county's previous schedule, so it is not a new charge in the 2026 adjustment. Both lines come from the fee schedule adopted at the Board of County Commissioners' public meeting of 28 October 2025, after public hearings on 21 and 28 October 2025, effective 1 January 2026, as the county's news releases of 17 November and 31 December 2025 state; the published PDF's page header still reads PROPOSED from the drafting stage. The charges apply in the jurisdictions on the county's chart: all nine townships, the cities of Brookville, Huber Heights, Riverside, Trotwood and Union (commercial only), the villages of Farmersville, New Lebanon and Phillipsburg, and WPAFB-PageManor.
