Do you need a building permit in Franklin County, Indiana?

Yes. Franklin County's Area Plan Commission and Building Department issues building permits and conducts inspections for construction throughout the county except within Batesville.1 The department's own page also says it issues building permits, administers zoning regulations and conducts building inspections outside Batesville.4

Indiana currently applies the state building and residential codes identified in the reviewed rules, with the particular code depending on the structure.7 State filing and a local permit are separate questions: even work exempt from state filing may still need Franklin County approval.8 A farm-use building that is not used for retail trade may fall outside Indiana's Class 1 state design-release category, but that status does not itself waive county permits or zoning.9

Who issues Franklin County building and zoning permits?

The Franklin County Area Plan Commission & Building Department is the first stop for building permits, inspections and zoning outside Batesville.4 The office is at the Franklin County Government Center in Brookville, and its official page lists its phone and email in the office card above.4 The department also receives applications for variances, conditional uses, rezones and subdivisions.4

A property inside Batesville is the stated exception to the county department's construction coverage, so a Batesville project should begin with the city rather than assuming the county will issue its approvals.1 For rural land elsewhere in Franklin County, describe the parcel, proposed use and every planned structure when contacting the department; that gives staff enough context to identify building, location-improvement, zoning or hearing requirements.4

Does Franklin County, Indiana have zoning?

Yes. Franklin County administers zoning through the Area Plan Commission and Board of Zoning Appeals.2 The planning office accepts petitions involving variances, conditional uses, rezones and subdivisions.4 That means a parcel's zoning district and proposed use matter in addition to the building permit itself.2

We could not confirm countywide numeric rules for minimum dwelling size, minimum lot size, setbacks, lot coverage or building height. Ask the Area Plan Commission & Building Department for the current zoning designation and the standards that apply to the specific parcel before designing a house, cabin or accessory building.4 If land will be divided outside a municipality, Indiana also requires the applicable subdivision plat and approval process before lots are sold.10

How do septic permits work in Franklin County?

The Franklin County Health Department administers local septic permitting under Indiana's state on-site sewage framework.3 The county's instruction sheet starts with a soils evaluation by a certified soil scientist and requires the soils test plus an installer's drawing for Health Department review before permit issuance.11 Residential and holding-tank septic permits are listed at $50, while a commercial septic permit is listed at $100.12

Site feasibility deserves early attention: only about 0.2% of mapped county soils avoid a “very limited” rating for conventional septic drain fields.13 That soil statistic does not decide an individual parcel, but it makes the county's site-specific soils evaluation especially important.13 Indiana residential sanitation generally requires a compliant septic tank and soil absorption system where sewer is unavailable, with holding tanks limited to specified circumstances.14

Can you live in an RV or tiny home in Franklin County?

We could not confirm Franklin County's rule for long-term RV occupancy, temporary camping or tiny-home occupancy on a private parcel. Ask the Area Plan Commission & Building Department about the parcel's zoning, the proposed length of occupancy, utility connections and whether the unit is treated as a dwelling before moving it onto the land.4

Indiana's campground rules do not answer whether someone may live in an RV on an individually deeded lot; the reviewed rule concerns regulated campgrounds and expressly has a different scope.15 A tiny home intended as a dwelling still enters a county system that requires building permits and administers zoning outside Batesville.12 We also could not confirm a local minimum dwelling size, so obtain a parcel-specific answer from the planning office before ordering a tiny home.4

Building a home in Franklin County: what are the steps?

  1. Confirm whether the parcel is outside Batesville and ask the Area Plan Commission & Building Department for its zoning district and applicable approvals.12
  2. Have the Health Department address septic feasibility early; its instructions begin with a certified soil scientist's evaluation.11
  3. Submit the required building and zoning materials to the county planning office, including any variance, conditional-use, rezone or subdivision petition the proposal needs.4
  4. Determine whether the project also needs Indiana design release; state filing does not replace local permits.8
  5. Obtain permission from the agency controlling the road before constructing a driveway in its right-of-way; INDOT handles connections to the state highway system through its electronic permit system.16
  6. Schedule and complete the county building inspections associated with the permitted construction.1

What should you check before buying land in Franklin County?

Start with buildability, not the listing description. Confirm zoning and permit coverage with the Area Plan Commission & Building Department, then ask Environmental Health whether the proposed homesite can support septic and whether a local private-well permit applies.236 Franklin County's mapped soils make conventional drain-field suitability a major due-diligence item.13

Check legal road access and identify which agency controls the road, because connections within a state-highway right-of-way require permission from INDOT.16 Check flood maps before siting improvements: Indiana DNR has jurisdiction over most development in floodways, while flood-fringe development can still face local requirements even though the state does not issue a fringe permit.1718 For carrying costs, the county's effective property-tax rate is about 0.6%, with a median annual bill around $1,459.1920

Watch-outs

  • Batesville is excluded from the Franklin County building department's stated construction coverage, so projects there should begin with the city.1
  • A state agricultural design-release exemption does not establish an exemption from Franklin County permits or zoning.9
  • Long-term RV occupancy, tiny-home standards, owner-builder exemptions and numeric setbacks remain unconfirmed; ask the Area Plan Commission & Building Department before purchase or placement.4
  • Mapped soils without severe conventional drain-field limits cover only about 0.2% of the county, so complete septic feasibility work before fixing a homesite.13

Indiana rules that apply here

  • Building permitLimited

    Building-permit or plan-review requirements for construction in Indiana; the state describes these as administrative provisions local jurisdictions may adopt and enforce.

    • Whether a building permit or plan review is required depends on the applicable local jurisdiction's administrative ordinance or process.
    • The cited IDHS statement says local jurisdictions retain authority to establish departments, create inspection schedules, establish fines, and create an order-review process.
    • IDHS states its summary represents the agency's position and is not binding; initial determinations about enforceability of a specific ordinance are left to the local unit administering it.
    “However, HEA 1575 did not eliminate the authority of local jurisdictions to adopt and enforce administrative provisions in building and fire safety ordinances, which include, among other things: (1) the establishment of departments; (2) the requirement to obtain a building permit or plan review; (3) the creation of inspection schedules; (4) the establishment of fines; or (5) the creation of an order review process.”
  • Building code adoptedAdopted (with conditions)

    Statewide Indiana construction subject to the Indiana Fire Prevention and Building Safety Commission's adopted building codes, including the Indiana Building Code and Indiana Residential Code.

    • The adopted codes consist of model codes amended for Indiana.
    • The 2014 Indiana Building Code under 675 IAC 13-2.6 is currently in effect and became effective December 1, 2014.
    • The 2020 Indiana Residential Code under 675 IAC 14-4.4 is currently in effect and became effective December 26, 2019.
    • Specific applicability depends on the structure and code category.

    Indiana Building Code effective date: 2014-12-01 · Indiana Residential Code effective date: 2019-12-26

    “The Fire Prevention and Building Safety Commission creates Indiana codes by adopting model codes and amending them to apply in Indiana.”

      “675 IAC 13-2.6 | 2014 Indiana Building Code | International Building Code, 2012 Edition, First Printing ANSI A117.1 Accessible and Usable Buildings and Facilities, 2009 Edition, First Printing | Currently in Effect Effective: 12/1/2014 675 IAC 14-4.4 | 2020 Indiana Residential Code Free access (model code with incorporated amendments) | 2018 International Residential Code for One- and Two-Family Dwellings, First Printing | Currently in Effect Effective: 12/26/2019”
  • InspectionsLimited

    Construction inspections in Indiana, including Class I structures in jurisdictions without an approved building department and construction subject to a Construction Design Release.

    • In jurisdictions without an approved building department, IDHS Code Enforcement inspects Class I structures for construction compliance.
    • When a Construction Design Release is applied for through the Building Plan Review Section, IDHS Code Enforcement conducts construction-process and final inspections.
    • Agricultural buildings and one- and two-family residential structures fall under the local government entity; if no local government entity exists, the county government may provide inspections, and IDHS states that if there is no local government entity the residential issue becomes a private civil matter.
    “In jurisdictions where there is not an approved building department, Code Enforcement inspects Class I structures for construction compliance. When a Construction Design Release is applied for through the Building Plan Review Section, Code Enforcement will conduct inspections during the construction process and provide a final inspection. Agricultural buildings and residential structures (one- and two-family dwellings) fall under the jurisdiction of the local government entity.”
  • Who permits septicMixed

    Indiana residential on-site sewage systems statewide; the Indiana Department of Health establishes and reviews the statewide rule while local boards of health administer it and local health departments issue permits.

    • The rule is administered by local boards of health through their health officers and authorized representatives.
    • Each local health department residential on-site sewage system permit program is subject to review by the Indiana Department of Health.
    “administered by the local boards of health [...] subject to review by the department.”
  • Off-grid sanitationLimited

    Residential sanitation in Indiana where a dwelling is not connected, or cannot be connected, to a sanitary sewerage system.

    • The dwelling must be provided with a compliant residential on-site sewage system including a septic tank and a soil absorption system that has not failed.
    • A temporary sewage holding tank is subject to written Indiana Department of Health approval, with specified exceptions for failed systems, soil conditions after a construction permit, and certain district, utility, or municipal sewage plans.
    • A holding tank operated as a primary residential disposal method for a sewer connection plan is limited to not more than one year unless the period is extended upon documentation of satisfactory operation.
    • Drywells and cesspools are not allowed for construction or use as on-site sewage treatment in Indiana.

    holding-tank sewer-connection period: <= 1 year (may be extended upon documentation of satisfactory operation)

    “septic tank and a soil absorption system”
  • Well permitLimited

    Construction of residential water-supply wells and installation of well pumps in Indiana.

    • Indiana Department of Health standards state that several local health departments require a permit before residential water-supply well construction or well-pump installation.
    • The cited statewide source does not identify which local health departments require permits; local requirements must therefore be checked for the specific property.
    • Water-well drillers must be licensed by the Indiana Department of Natural Resources.
    “Several local health departments now require that a permit be obtained before construction of a residential water supply well or installation of a well pump.”
  • Agricultural exemptionAvailable (with conditions)

    Buildings used only for an agricultural purpose on the land where they are located and not used for retail trade, for purposes of Indiana state Class 1 construction-design-release requirements.

    • The building must be used only for an agricultural purpose.
    • The building must be located on the land where the agricultural purpose occurs.
    • The building must not be used for retail trade.
    • This is an exemption from Class 1/state design-release classification; it does not establish exemption from every local inspection, zoning, building, fire, or other applicable requirement.
    • Indiana's official Code Enforcement FAQ states that local units of government inspect agricultural buildings if they have an ordinance requiring inspection.

    state design-release classification: not Class 1 (Does not resolve local inspection or zoning requirements)

    “Buildings used only for an agricultural purpose on the land where they are located and not used for retail trade are not Class 1 structures.”

    • The plat must show public places, public ways, and the length, width, and size of each lot.
    • A registered land surveyor must certify the correctness of the plat.
    • The subdivision plat must be submitted for approval by the board of county commissioners.
    • The county recorder may record the plat only if a certificate showing approval of the county commissioners is attached.
    • Once a subdivision-control ordinance is adopted and filed, the plan commission has exclusive control over approval of plats and replats covered by that ordinance.
    • The cited state summary distinguishes subdivisions outside municipalities; incorporated municipalities may have separate statutory or local procedures.
    “Subdivisions Outside Cities and Towns: A person who lays out a subdivision of lots or lands outside the corporate boundaries of any municipality shall record a correct plat of the subdivision in the office of the recorder of the county before selling any lots in the subdivision. The plat must show public places, public ways, and the length, width, and size of each lot.”

    “State law requires the public to obtain permission from the governmental unit having jurisdiction over a street or highway”
  • Building in a floodplainLimited

    Development activities within the fringe portion of Indiana floodplains.

    • There is no state review or state permit for fringe development.
    • When a community adopts floodplain regulations, the regulations must be approved by the Department and may not be less restrictive than 312 IAC 10.
    • Most Indiana communities participate in the NFIP, which requires certain federal regulations to be adopted and enforced for the entire floodplain.

  • Campground & park staysLimited

    Recreational vehicle occupancy at a regulated Indiana campground campsite, rather than residential occupancy on an individually deeded lot or other land outside the rule's campground definition.

    • A campground is an area where campsites are leased or rented and provisions are made for ten or more tents, recreational vehicles, park models, or vacation mobile homes.
    • The campground must be established, operated, and maintained for recreational, health, education, sectarian, business, or tourist activities away from established residences.
    • The rule excludes primitive campgrounds, youth camps, and tracts of land divided into individually deeded lots.
    • No more than one recreational vehicle or one vacation mobile home may be allowed on a designated campsite at the same time.
    • Campground construction, additions, or significant construction changes require plans submitted at least ninety days before construction for department review and approval; the plans must be certified by a registered engineer or architect licensed in Indiana.
    • The rule does not establish a general statewide authorization for long-term residential RV occupancy outside regulated campgrounds.

    minimum campground provisions: >= 10 tents, recreational vehicles, park models, or vacation mobile homes · maximum recreational vehicles per designated campsite: 1 vehicle (one vacation mobile home may be used instead) · advance plan-submission period: >= 90 days (the department may waive plan review for a minor alteration)
