Porter County, Indiana requires a building permit for virtually every construction project, including a separate improvement location permit for new homes, both handled by the Porter County Building Department1. The county also has zoning: its Unified Development Ordinance sets zoning districts and development standards administered by the county Plan Commission2. Septic systems need a permit from the Porter County Health Department's Environmental Division before installation, and so do most private wells3.

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

Porter County requires a building permit for almost every construction project, and new homes also need a separate improvement location permit before work can start1. Indiana leaves the building-permit decision to local option: state law didn't eliminate local authority to require "a building permit or plan review," and Porter County has exercised that authority rather than leaving construction unregulated8. Applications go through the county's online portal at permitting.schneidergis.com, where "All Contractors will need to register in the new Portal"9. Statewide, Indiana's own model codes -- the 2014 Indiana Building Code and the 2020 Indiana Residential Code -- set the baseline construction standards Porter County's building department enforces10. Farm buildings used only for an agricultural purpose and not used for retail trade can skip the state's Class 1 design-release review, though that exemption doesn't excuse a project from Porter County's own zoning, building or inspection requirements11.

Who is the Porter County building department, and how do you reach them?

The Porter County Building Department "processes applications for almost every building project and performs subsequent inspections"9. Reach the department at 155 Indiana Avenue, Valparaiso, Indiana 46383, phone 219-465-3676, for general permit questions9. Building, planning and zoning questions go to 219-465-3540, and building inspections are scheduled separately at 219-465-34739. All permit applications, contractor registrations and inspection scheduling now run through the county's online portal at permitting.schneidergis.com, and every contractor, not just new ones, must create an account there9.

Does Porter County have zoning?

Porter County has zoning countywide, set out in its Unified Development Ordinance, which establishes zoning districts and development standards administered by the county Plan Commission2. That's a meaningful contrast with some rural Indiana counties, where the state leaves building and zoning regulation up to local option and a county can choose not to adopt either one8. For zoning questions specific to your parcel, such as setbacks, permitted uses or a board of zoning appeals variance, call the Development & Storm Water department's planning and zoning line rather than the general building-permit number12. Because the Unified Development Ordinance also contains Porter County's subdivision regulations, any plan to split off a smaller lot should start with the Plan Commission, not just the county recorder2.

How do septic and well permits work in Porter County?

Septic systems in Porter County need a permit from the Porter County Health Department's Environmental Division before installation, and so do most private wells3. For a repair, the Environmental Division sends an inspector to the site, and "residential repair permits are valid for two years"4. For new construction, a private, certified soil scientist must complete a soil test, the health department reviews the site plan within three to five days, and once approved, "septic permits expire two years from the date of issuance," while "well permits have no expiration date"4. Wells must sit "at least 50 feet from septic tanks, laterals, and sewer lines"4. Fees run $275 for a combined well and septic permit and $50 for a well permit alone4. Only about 8.6% of Porter County's soils are rated free of severe limitations for a conventional drain field, which lines up with the county's soil-test requirement: budget time and money for that step rather than assuming a standard system will pass5. Statewide, Indiana requires any on-site system to include a septic tank and soil absorption system, bans drywells and cesspools outright, and caps a temporary holding tank at one year unless the period is extended13.

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

Indiana's campground rule caps occupancy at one recreational vehicle per designated campsite in a licensed campground, but that rule governs commercial and rental campgrounds, not whether you can live in an RV on your own deeded lot in Porter County14. Living in an RV, tiny home or manufactured home on private land in Porter County instead comes down to the Unified Development Ordinance and whatever zoning district covers your parcel, since Porter County zones countywide2. Call the Development & Storm Water department's planning and zoning line before setting one up as a residence, since permitted uses and any manufactured-home standards vary by zoning district12. No official Porter County page found this session spells out an owner-builder exemption from the permit process either, so confirm directly with the Building Department if you plan to build it yourself7.

Building a home in Porter County, Indiana: the steps, in order

  1. Confirm your parcel's zoning district under the Unified Development Ordinance and call the Development & Storm Water department's planning and zoning line with any use or setback questions2.
  2. Create an account at permitting.schneidergis.com and register as a contractor if you aren't building it yourself, since "All Contractors will need to register in the new Portal"9.
  3. Apply for your building permit and improvement location permit through the Porter County Building Department before construction starts1.
  4. If you need a well or septic system, contact the Porter County Health Department's Environmental Division for a site visit; new construction also requires a soil test from a private, certified soil scientist4.
  5. Wait for the health department's site-plan review, since Porter County Health Department staff will review the site plan within three to five days before your well and septic permit is issued4.
  6. Schedule building inspections by calling 219-465-3473 as work progresses9.
  7. Track your septic permit's two-year clock from issuance so approvals don't lapse before you finish4.

What to check before you buy land in Porter County, Indiana

Confirm the zoning district for any parcel you're considering, since Porter County zones countywide under its Unified Development Ordinance and that district governs what you can build, park or live in2. Test the soil before you count on a conventional septic system: only about 8.6% of Porter County's soils are rated free of severe limitations for a drain field, and the health department will require its own soil test and site-plan review either way54. If the parcel needs a new well, budget for a $50 well permit, or $275 if you need both a well and septic permit at once4. If the access road connects to a state highway rather than a county road, a driveway onto that highway needs its own INDOT permit, and a private driveway approach currently runs $551516. Check whether the parcel sits in a floodway: Indiana's DNR Division of Water has jurisdiction over most floodway development, while the less-restricted "fringe" portion of a floodplain has no state permit but may still need a local one1718. Porter County sits about 41 miles from the nearest metro area, with a population density around 419 people per square mile and an effective property tax rate near 0.8%, with a median annual bill close to $2,17219202122.

Watch-outs

  • No official Porter County page confirms an owner-builder exemption from the permit process, so ask the Building Department directly before skipping a licensed contractor7.
  • Indiana's state campground rules only cover licensed and temporary campgrounds, not living in an RV on your own land in Porter County; that depends on the parcel's zoning district instead142.
  • A driveway that connects to a state highway in Porter County needs its own INDOT permit separate from any county or township approval15.

    Porter County Unified Development Ordinance ↗Scouted from the county site, not yet independently re-checked

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.”
  • 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.”
  • Subdividing landRegulated (with conditions)

    Subdivision of lots or lands outside the corporate boundaries of a municipality in Indiana.

    • A correct plat must be recorded with the county recorder before selling lots.
    • 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.”
  • Driveway accessRequired

    Driveway connections and construction inside the right-of-way of Indiana state highways.

    • The governmental unit having jurisdiction over the street or highway must grant permission.
    • INDOT jurisdiction is limited to the Indiana state highway system; other governmental units may use the guide as a guideline.
    • Applications must be made through the INDOT Electronic Permit System.
    “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.
    • Local permits may still be required.
    “There is no State review of or permit issued for development activities within the fringe portion of the floodplain.”
    One more reviewed finding on this topic
    • Required — Most development activities in Indiana floodways, including fills, excavations, bridges, utilities, and non-residential structures.
      “The DNR Division of Water has jurisdiction in Indiana's floodways for most development activities.”
  • Permit feesPublished (with conditions)

    Published fees for specified Indiana DNR Division of Water and INDOT permits statewide.

    • Fees apply to the specified permit types and do not establish a single fee for every Indiana permit.
    • DNR lists fees by statute and permit application type; INDOT fees vary by driveway or road-approach subtype.

    DNR Flood Control Act excavation, fill, or non-residential construction in a floodway application fee: 200 USD · DNR Flood Control Act residential reconstruction in a floodway other than the Ohio River floodway application fee: 50 USD · DNR Flood Control Act residential construction or reconstruction in the Ohio River floodway application fee: 10 USD · INDOT private driveway, private field access, temporary driveway, or driveway removal fee: 55 USD · INDOT minor or sub-minor commercial driveway or minor public road approach fee: 150 USD · INDOT major commercial driveway or major public road approach fee: 600 USD

    • The process applies to projects required to file with IDHS for a construction design release.
    • All work, including work exempted from state filing, may require local permits.
    • If additional documents are uploaded before the initial response, the 10-business-day period restarts.

    “If your project is selected for a review, you will either receive a release or request for corrections to your plans within 20 business days”
  • 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)
