Do you need a building permit in Mahoning County, Ohio?
Yes. New buildings and alterations to existing structures in unincorporated Mahoning County require a building permit1. The county's Building Inspection Department also reviews plans in Campbell, Canfield, Craig Beach, Lowellville, New Middletown, Poland, Struthers and Youngstown11. Like most counties around it in Ohio, Mahoning County requires a county building permit11.
The department enforces the Residential Code of Ohio for one-, two- and three-family homes and accessory structures, plus county building regulations adopted in 2009 that cannot conflict with the state code1213. Field checks include footings, foundations, framing after mechanical work, and a final inspection before occupancy; a certificate of occupancy follows141516.
An owner may claim a narrow county exemption for a qualifying agricultural accessory structure8. Ohio also excludes a specific agricultural building from listed building-code provisions when a county or township zoning inspector certifies its agricultural use, but zoning, health, septic and floodplain requirements may still apply17.
Who is the Mahoning County building department, and how do you reach it?
The Mahoning County Building Inspection Department is at 50 Westchester Drive, Room 201, Austintown, OH 44515, and its phone number is 330-270-289418. Its webpage provides a permit-inquiry search and a published fee schedule1819.
Residential permits are priced at $2.50 per $1,000 of construction cost index value plus a $10 flat fee, and residential plan approvals and permits carry a 1% state assessment; inspection, occupancy and other services have their own listed fees2021. Applicants provide the job-site address, township zoning and floodplain approvals, sewer or septic documentation, a downspout permit, plans, construction details and licensed-subcontractor information22. Plan review usually takes about 1–2 working days22.
Does Mahoning County have zoning?
Mahoning County does not have one zoning answer for every parcel: township, village and city requirements vary2. The county's 2024 zoning directory lists zoning officials for many communities and names Springfield Township, Beloit and Washingtonville as having no zoning5. Inside the cities and villages that run their own zoning, including Struthers23, Campbell24, Canfield25, Youngstown26, Poland27, New Middletown28 and Lowellville29, the local code governs. Septic and well permits for those addresses still come from Mahoning County Public Health3.
Where zoning applies, obtain the zoning permit from the township, village or city as part of the residential building process30. The county GIS publishes zoning district and JEDD overlay layers, but not ordinance text or district dimensional rules31. County subdivision rules do not replace local zoning2. We could not confirm one countywide standard for setbacks, minimum dwelling size, accessory dwellings, RVs or tiny homes; ask the parcel's zoning office.
How do septic permits work in Mahoning County?
Ohio regulates household sewage treatment systems, while Mahoning County Public Health conducts local permitting, inspections and enforcement under state and county health-district rules32. When public sewer is unavailable, a new, replacement or altered household system needs site review and approval before an installation permit33. The site-review package includes a fee, soil report and site plan, followed by a health-department site visit344.
A Sanitarian inspection is also required before an addition that increases bedrooms or changes the footprint, before another structure is added, and before an existing structure on a septic-served property is replaced435. Mahoning County's soil data rates 0% of mapped soils as free from severe limits for a conventional drain field, so make septic feasibility an early question36. If sanitary sewer is available, obtain a tap permit from the county, city or village authority instead37.
Can you live in an RV or tiny home on your land in Mahoning County?
We could not confirm one countywide rule allowing long-term RV occupancy or tiny-home occupancy on private land in Mahoning County. Because zoning requirements vary by township, village and city, ask the zoning office for the parcel whether the proposed unit is an allowed dwelling, what dimensional rules apply and whether temporary occupancy during construction is permitted38. Ohio's campground rule controls RV placement in licensed and temporary campgrounds, but it does not answer whether someone may live in an RV on an ordinary private parcel39. A manufactured home is subject to a separate statewide safeguard: it generally cannot be occupied until the state inspector issues an inspection seal40. County building, septic or utility approvals may still be needed depending on the structure and site141.
Building a home in Mahoning County: what are the steps, in order?
Identify the township, village or city and obtain approval from the local zoning department where required2.
Obtain the driveway or curb-cut permit from the township, village, city, county or state agency responsible for the road42.
Determine whether sewer and city water serve the parcel; obtain the sewer tap permit when sewer is available, or secure septic site approval when it is not4133.
If city water is unavailable, choose a licensed well driller to obtain the well permit from the District Board of Health, then obtain the required safe water sample43.
Get floodplain approval from the Mahoning County Planning Commission, which the residential permitting sheet requires for county projects; development in a special flood hazard area needs a floodplain development permit before work begins4445.
Complete footer-drain and downspout approvals, then apply for building and HVAC permits and arrange plumbing and electrical approvals30.
Complete the required inspections and obtain the occupancy approval before occupying the structure1516.
What should you check before you buy land in Mahoning County?
Start with parcel jurisdiction because zoning requirements vary across Mahoning County and the building department's service area is defined separately21. Verify sewer and water availability before pricing the project; available sewer requires a tap permit, while land without sewer needs county septic review, and a site without city water needs a well permit obtained through a licensed driller63346. Conventional septic feasibility deserves special attention because 0% of mapped county soils are rated free from severe drain-field limitations36. Check the flood map because county residential permits require floodplain approval from the Planning Commission, and covered work in a special flood hazard area requires a floodplain development permit before construction begins4445. Identify which authority controls the road access and driveway permit47. A land division in unincorporated Mahoning County may require Planning Commission review, including a division creating a lot smaller than 5 acres48.
Watch-outs
Zoning varies by township, city and village, and Springfield Township, Beloit and Washingtonville are listed with no zoning, so identify the parcel's jurisdiction and confirm with that zoning office5.
Mahoning County's soil data rates 0% of mapped soils as free from severe limits for a conventional drain field, making septic feasibility an early due-diligence item36.
Mahoning County's owner-builder exemption is limited to qualifying agricultural accessory structures; personal, recreational or commercial use requires approval and permits8.
County residential permits require floodplain approval from the Mahoning County Planning Commission, so check the flood map before you design44.

Subdividing landRegulated (with conditions)
Subdivision of land in the unincorporated areas of Mahoning County under the Mahoning County Subdivision Regulations administered by the Mahoning County Planning Commission.
The regulations apply to unincorporated areas of Mahoning County.
They also apply to an incorporated area only where a planning assistance contract has been lawfully adopted for joint administration under Ohio Revised Code section 713.23.
The regulations cover division of a parcel into two or more lots where any lot is less than five acres or the minimum state standard.
They cover allocation of rights-of-way and easements, open space and public land, annexation of parcels to incorporated areas, and certain transfers between adjoining property owners where no additional building sites are created.
A division or partition into parcels of more than five acres each is not subject to these regulations when it does not involve new streets or an easement of access.
The county guidance directs buyers in townships or villages to contact the Planning Commission, but excludes the cities of Campbell and Canfield.
lot-size threshold: < 5 acres (The division of land into parcels of more than five acres each is excluded when no new streets or easement of access are involved.)
“These regulations shall apply to the unincorporated areas of Mahoning County”
Driveway accessRequired
New residential construction requiring access from a public road.
The required driveway or curb-cut permit may be issued by the township, village, city, county, or state, depending on the road and location.

Building in a floodplainRequired
Construction and other development activity wholly within, partially within, or in contact with an identified special flood hazard area within Mahoning County jurisdiction, including filling, grading, construction, alteration, remodeling, expanding a structure, or altering a watercourse.
A floodplain development permit must be obtained before commencement of covered construction or development, and the permit must show conformity with the county regulations.
The regulations apply to all areas of special flood hazard within Mahoning County jurisdiction as identified by the adopted Flood Insurance Study, Flood Insurance Rate Map, other adopted studies or maps, or approved hydrologic and hydraulic analysis.
The application must be submitted by the property owner or authorized agent before construction begins; if it is unclear whether the site is in a special flood hazard area, the Floodplain Administrator may require an application to determine the site's location.
Applications must include scaled site plans; certified existing-ground and lowest-floor elevations; other information requested by the Floodplain Administrator; applicable technical analyses; and a fee set by Mahoning County's adopted Schedule of Fees.
The Floodplain Administrator reviews a complete application only after all required information is received and must ensure that required federal, state, and local permits have been obtained, including applicable U.S. Army Corps of Engineers permits under Section 10 of the Rivers and Harbors Act and Section 404 of the Clean Water Act and Ohio Environmental Protection Agency permits under Section 401 of the Clean Water Act.
The Floodplain Administrator must approve or disapprove a complete application within thirty days; an approved permit is conditional on work commencing within one year and expires one year after issuance unless the permitted activity has been substantially begun and thereafter pursued to completion.
A permit application is not required for maintenance work such as roofing, painting, and basement sealing, or for small nonstructural development activities, except filling and grading, valued at less than $5,000.
A permit application is not required for development activities in an existing or proposed manufactured home park under Ohio Department of Health authority and subject to Ohio Administrative Code Chapter 3701 flood-damage-reduction provisions; major utility facilities permitted by the Ohio Power Siting Board under Ohio Revised Code Chapter 4906; hazardous-waste disposal facilities permitted by the Hazardous Waste Siting Board under Ohio Revised Code Chapter 3734; or development activities undertaken by a federal agency subject to Federal Executive Order 11988.
Any action exempt from filing for a floodplain development permit is also exempt from the standards of these regulations.
Where FEMA has provided base-flood elevations but no floodway, the application may require hydrologic and hydraulic analysis demonstrating that cumulative development will not increase the base-flood water-surface elevation by more than one foot; development in an identified floodway requires hydrologic and hydraulic analysis showing its impact on flood heights.
The county regulations state that the resolution was adopted on October 8, 2009 and takes effect on the thirty-first day following adoption; the effective date is therefore November 8, 2009.
More restrictive applicable resolutions, zoning, subdivision regulations, or building codes control in the event of conflict.
small nonstructural development exemption threshold: < 5000 USD (Filling and grading are excluded from this exemption.) · complete-application review deadline: 30 days · permit commencement deadline: 1 year (The permit expires one year after issuance unless the permitted activity has been substantially begun and thereafter pursued to completion.) · maximum cumulative base-flood elevation increase where FEMA provides base elevations but no floodway: <= 1 foot (A hydrologic and hydraulic analysis is required.)
“It shall be unlawful for any person to begin construction or other development activity [...] until a floodplain development permit is obtained from the Floodplain Administrator.”

county zoning authorityGeneral
County commissioners may adopt zoning resolutions regulating building, structures, land uses, and districts or zones in unincorporated territory statewide.
The authority is exercised by resolution and must be in accordance with a comprehensive plan.
The authority applies to unincorporated territory of the county.
The statute begins with the exception phrase “Except as otherwise provided in this section,” so the limitations in ORC Chapter 303 apply.
For nonresidential property only, the county may regulate height, bulk, number of stories, size, lot coverage, yards, courts, open spaces, and population density.
Agricultural uses and agricultural buildings are subject to the limitations in ORC 303.21; the statute also contains limitations for public utilities, railroads, telecommunications towers, alcoholic-beverage sales, oil and gas drilling, and permanently sited manufactured homes.
Activities regulated under ORC Chapters 1513 and 1514 may be regulated only in the interest of public health or safety, and Chapter 1514 activities must be provided for as permitted or conditional uses as specified by ORC 303.02.
“the board of county commissioners may regulate by resolution, in accordance with a comprehensive plan”
county building authorityGeneral
County commissioners may adopt and enforce local residential building regulations in unincorporated areas and may operate certified county building departments that enforce state residential and nonresidential building codes, accept and approve plans, and conduct inspections.
Local residential building regulations may be enforced within the unincorporated area or within districts established in the unincorporated area.
A local residential building regulation may not differ from the state residential building code unless it addresses subject matter not addressed by that code or is adopted under ORC 3781.01.
An existing structures code must concern subject matter not addressed by, and may not conflict with, the state residential building code.
County building departments may enforce state codes only for the types of buildings and subject matters for which they are certified.
Certification permits enforcement authority, plan approval, and inspections; the certification application identifies whether it covers residential or nonresidential buildings and whether residential certification covers new construction only or also repair and alteration.
The board may adopt flood-hazard, Lake Erie coastal-erosion, and drainage regulations, subject to the statutory limits and exceptions in ORC 307.37.
Local regulations, codes, or amendments require public hearings at not fewer than two regular or special board sessions; they take effect on the thirty-first day after adoption.
Regulations adopted under ORC 307.37 generally do not affect buildings or structures existing, or under construction, before adoption, except as provided for an existing structures code.
The state residential building code is effective as a uniform requirement in areas with a building department certified to enforce it.
“The board of county commissioners may adopt local residential building regulations governing residential buildings as defined in section 3781.06 of the Revised Code”
