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

A new structure on unincorporated Marion County land requires improvement-location, drainage and structural permits through the city-county residential development process1. The improvement-location permit covers a proposed new structure, added square footage or height, and other site improvements unless Indy Rezone provides an exemption9. The 2020 Indiana Residential Code applies statewide to Class 2 structures and their accessory structures, using the 2018 International Residential Code as modified by Indiana16. After permits are issued, inspections are required throughout construction; the site must remain open and accessible2. Business and Neighborhood Services should confirm the exact permit set before final plans because requirements depend on the structure and site9.

Who issues Marion County building permits, and how do you reach them?

For unincorporated Marion County, the Department of Business and Neighborhood Services handles residential building and zoning review at 1200 S Madison Ave, Indianapolis, Suite 100; call (317) 327-8700 or email permitquestions@indy.gov19. Inside Beech Grove, Speedway and Southport, the municipality issues its own building permits456. Septic permits remain with the Marion County Public Health Department throughout the county7. BNS residential development permits each carry a $32 application fee in addition to the permit fee; structural permits other than structural renovation permits also carry a plan-review fee17. An owner applying for a structural permit must sign a Statement of Intent and Understanding, while trade permits have added restrictions13.

Does Marion County have zoning?

Unincorporated Marion County uses the consolidated Indy Rezone ordinance, and applicants must identify the parcel’s zoning district before applying310. Speedway and Southport have their own zoning; septic systems in those municipalities remain under the Marion County Public Health Department18197. Minimum setbacks and maximum lot coverage apply by zoning district, and site plans must show distances from the front, rear and side property lines1112. The official GIS service publishes zoning and related layers, but its map is informational rather than the legal ordinance; confirm the district and standards against the current official map and ordinance20. We could not confirm current numeric minimum-home-size, minimum-lot-size or building-height rules, so ask Business and Neighborhood Services about the parcel and proposed house, accessory building, RV or manufactured dwelling9. Indiana’s agricultural design-release classification does not remove local zoning, permit or inspection requirements21.

How do septic permits work in Marion County?

The Marion County Public Health Department administers onsite wastewater systems in Marion County under state standards and the county health code7. The department requires a permit for new septic construction and repair of an existing system; the work must meet 410 IAC and Chapter 14 standards, and installers must hold IOWPA certification8. Call the onsite-sewage program at 317.221.2266 before fixing a house location or closing on an unsewered lot22. Countywide soil data rates 0% of mapped soils as free of severe limitations for a conventional drain field, but that screening statistic does not replace a parcel evaluation15. Where new construction will connect to sewer, a Citizens Energy Group sewer-connection permit is required before the structural permit can issue23. Indiana requires a compliant septic tank and soil-absorption system where a dwelling cannot connect to sanitary sewer and does not allow drywells or cesspools for onsite treatment24.

Can you live in an RV or tiny home on your land in Marion County?

We could not confirm a Marion County rule that gives a general right to live long-term in an RV on a private lot, so ask Business and Neighborhood Services about the parcel’s zoning and the exact proposed use before buying39. Indiana’s campground rule does not answer the private-lot question because it governs regulated campgrounds and excludes tracts divided into individually deeded lots25. We could not confirm a separate countywide tiny-home category or minimum home size, so ask Business and Neighborhood Services how a proposed site-built tiny home fits the zoning and residential building-permit requirements31. Any occupied dwelling without sewer service still needs a compliant sanitation solution; Indiana’s residential rule does not permit a drywell or cesspool as a substitute24.

Building a home in Marion County: the steps, in order

  1. For unincorporated Marion County, identify the parcel’s zoning district, setbacks and lot-coverage limit before fixing the site plan101112.
  2. Choose sewer or onsite sewage; a planned sewer connection needs a Citizens Energy Group permit before the structural permit, while new septic construction needs a county health permit and an IOWPA-certified installer2378.
  3. If the property will use a private well not serving a municipality or public utility, have a licensed driller obtain the health permit before construction and budget the $50 fee14.
  4. Confirm improvement-location, structural, drainage, driveway and any flood permits with Business and Neighborhood Services1926.
  5. Submit plans and budget for published permit, application and plan-review fees917.
  6. Use a licensed contractor or meet the added owner-builder conditions for each permit type13.
  7. Keep the site accessible for required inspections throughout construction2.

What should you check before buying land in Marion County?

Check zoning, wastewater, water, flood exposure and legal road access before treating a parcel as buildable3271428. Marion County requires a flood permit for structural work or land alteration in a flood zone, and a floodway or floodplain site plan must be certified by a professional engineer, land surveyor or architect26. Indiana DNR also regulates most floodway development, while flood-fringe work may avoid state review but still requires the local review293026. A state-highway driveway requires permission through INDOT’s electronic permit system28. For an unsewered parcel, discuss suitability with the county health department because countywide soil data rates 0% as free of severe conventional drain-field limitations1522. A private well not serving a municipality or public utility needs a $50 permit obtained by a licensed driller before construction; emergency drilling may begin before the permit only if the driller first notifies the Health Officer by telephone14. Within 30 days after drilling, the driller must give the Health Officer and owner a copy of the well record submitted to Indiana DNR14. The effective property-tax rate is about 0.9%, with a median annual bill near $1,9233132.

Watch-outs

  • Do not use Indiana’s campground limits as an answer about living in an RV on a private Marion County lot; ask Business and Neighborhood Services about the parcel and proposed occupancy259.
  • The countywide 0% soil figure is a screening measure for conventional drain fields, not a parcel-specific denial; seek a site evaluation from the Marion County Public Health Department1522.
  • A flood-zone project can require both Marion County review and Indiana DNR review when the work is in a floodway2629.

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)

    • 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.”
    3 more reviewed findings on this topic
    • Adopted — Class 2 structures and accessory structures, including one- and two-family residential construction in Marion County, subject to the Indiana Residential Code.
      “The 2020 Indiana Residential Code (675 IAC 14-4.4) went into effect on December 26, 2019. It applies to all construction on Class 2 structures and their accessory structures. The document consists of the International Code Council's (ICC) model 2018 International Residential Code, as modified by Indiana state amendments. Since that date, the 2020 Indiana Residential Code has been in full force and effect in every location within the state of Indiana.”
    • Adopted (with conditions) — One- and two-family residential construction in Marion County under Indiana's statewide residential building-code regime.
      “675 IAC 14-4.4 | 2020 Indiana Residential Code [...] 2018 International Residential Code for One- and Two-Family Dwellings, First Printing | Currently in Effect Effective: 12/26/2019”

    • 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”
  • Agricultural exemptionConditional

    Indiana agricultural buildings or structures evaluated for the Class 1 structure agricultural-purpose exemption.

    • The structure must be used for an agricultural purpose, generally related to cultivation of soil, production of crops, or raising livestock.
    • The structure may not be used for another purpose such as a restaurant or event center.

    • If any stated condition fails, the agricultural exemption does not apply.

    maximum consecutive months for farm-produce retail stand: <= 8 months (Retail trade in a structure that is not a stand disqualifies the exemption regardless of duration.)

    “If no, the agricultural exemption applies, and the building or structure is not a Class 1 structure”
    One more reviewed finding on this topic
    • Available (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.

    • 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.”
