Off-Grid Living in Perry County, Indiana

I undertook research into Perry County's off-grid rules by reviewing county planning and health department documentation, state regulations, and applicable Indiana code. What I found is that Perry County has a clear but narrow regulatory footprint: mandatory permitting for septic systems and private wells, required building documentation, but substantial gaps in published guidance on zoning, dwelling types, greywater, rainwater, and utility disconnection. Here is how that translates to practical next steps for someone actually planning to live off-grid here.

Zoning: Unclear and Requires Direct Inquiry

Perry County Planning and Zoning Department, headquartered in Tell City, administers county-level zoning, but the county does not publish specific off-grid or raw-land zoning criteria online. This is not unusual in rural Indiana, but it means you must contact the department directly—by phone or in person—before committing to a property purchase.

The critical question is whether your intended parcel falls in a zoning district that permits off-grid habitation or whether you would need a conditional use permit. Some counties in Indiana have explicitly carved out allowances for rural or agricultural residential uses that are compatible with off-grid systems; others default to general residential requirements that may or may not be friendly to septic and well use. Perry County's stance is unconfirmed. I recommend calling the Planning and Zoning Department and asking: *What zoning districts permit private dwellings with individual septic and well systems? Is a conditional use permit required for off-grid residential use? Does the county have any per-acre minimum lot sizes that apply to septic or well properties?* Write down the name and email of the person who answers; you may need to reference that conversation later when applying for permits. This is your gateway decision—if zoning prohibits or requires extensive variance procedures for off-grid use, the downstream permitting will be significantly harder.

Dwelling Type: Unclear—Town and Township Variation Possible

Perry County does not publish dwelling-specific regulations, and the verdicts suggest that rules may be set at the town or township level rather than uniformly at the county. This is important for anyone considering a tiny home, RV, or non-traditional structure.

At the state level, Indiana's "Log Cabin Rule" (IC 36-7-8-3(d)) may protect tiny homes on foundations, but the rule applies narrowly, and county or local enforcement varies widely. Tiny homes on wheels are typically classified as recreational vehicles (RVs) and generally cannot legally serve as permanent residences outside RV parks or mobile home parks in Indiana. If you are planning to place an RV, mobile home, or unconventional dwelling on raw land in Perry County, you must confirm with the Planning and Zoning Department whether that structure is permitted as a primary residence or whether a temporary occupancy permit, variance, or conditional use approval is necessary. Do not assume a structure that qualifies elsewhere in Indiana will be automatically approved in Perry County.

Building: Required Improvement Location Permit, Conditional on Septic Approval

Perry County Planning and Zoning issues an Improvement Location Permit for new structures. This is a necessary but not sufficient step. The county's building permit process has a critical gate: before a dwelling permit is issued, you must provide either a Septic Permit from the Perry County Health Department or a Sewer Tap-in Receipt (proof you have connected to municipal sewer).

This is not a formality. If you plan to use a private septic system—which is the standard for off-grid living in rural Perry County—the Health Department must review and approve your septic design and installation plan *before* you apply for a building permit from Planning and Zoning. If you ignore this sequence and build first, you risk being unable to legally occupy the structure. The practical order is:

1. Confirm zoning eligibility for off-grid use (Planning and Zoning Department). 2. Obtain a Septic Permit or Private Water Program permit (Health Department, see below). 3. Apply for the Improvement Location Permit (Planning and Zoning). 4. Obtain a building permit with proof of septic approval attached (Planning and Zoning). 5. Build and have final inspections.

Do not reverse this sequence.

Septic Systems: Restricted—Health Department Approval Required Before Installation

The Perry County Health Department administers septic permits for all properties where public sewage is not available. This is mandatory. You cannot legally install or alter a septic system without Health Department approval.

Here is what that process entails: You submit a septic system design (typically prepared by a licensed septic designer or engineer) to the Health Department. The design must comply with Indiana's state wastewater regulations (administered by the Indiana State Department of Health). The Health Department reviews the design for site compatibility, soil conditions, groundwater proximity, and setbacks from wells, property lines, and surface water. If approved, you receive a Septic Permit, which you then provide to the county Planning and Zoning Department as a prerequisite for a building permit.

I did not find Perry County-specific rules on composting toilets or alternative treatment systems. Many counties in Indiana have begun to permit dual-system designs (septic with a composting toilet as a secondary disposal or alternative), but Perry County's position is unconfirmed. If you are considering a composting toilet, greywater treatment, or other alternative to a conventional septic tank, contact the Health Department and ask whether the system complies with state wastewater rules and whether you need a separate permit. The Health Department's email and phone number should be available on the county website.

Greywater Reuse: Unclear and Likely Requires State-Standard Confirmation

Perry County does not publish specific greywater reuse regulations. At the state level, Indiana has no dedicated statute explicitly legalizing residential greywater reuse, though the Indiana Residential Code incorporates sections of the International Plumbing Code (IPC) that address certain greywater uses. The gap is significant: you may be legally permitted to reuse greywater under state code, but the Health Department has not publicly confirmed Perry County's stance.

If you plan a greywater system (reusing sink, shower, or laundry water for landscape irrigation or toilet flushing), contact the Perry County Health Department directly and ask: *Does Perry County permit residential greywater reuse? If so, are there design standards, setback requirements, or permit requirements I need to follow?* Be prepared for the answer to be "we do not have a specific rule—you would need to comply with state code," which is itself useful clarity. If the Health Department defers to state rules, ask them to point you to the specific state regulation or code section that applies. This conversation should happen *before* you finalize your off-grid design, because greywater reuse can meaningfully reduce septic load and water demand, and it may or may not be feasible depending on local approval.

Rainwater Harvesting: Unclear—Likely Permitted but Requires Confirmation

Indiana places no state-level restrictions on rainwater harvesting, and the 2020 Indiana Residential Code includes guidance for residential collection systems. However, Perry County does not publish specific rainwater regulations, and county-level rules can vary.

In practice, a residential rainwater harvesting system for landscape use or non-potable applications is very likely legal in Perry County, but you should confirm with the Health Department or Planning and Zoning before finalizing your off-grid water plan. Ask specifically: *Are there any county-level restrictions on rainwater collection for residential use? Are there size, design, or permit requirements?* Note that rainwater is not permitted for public potable use in Indiana (meaning you cannot treat rainwater as a substitute for a permitted well for drinking water), but supplementary rainwater for landscape irrigation or toilet flushing is generally allowed. If you are planning a roof-collection system, gutters, and cistern, this conversation with the Health Department will save you from retrofitting later.

Private Wells: Restricted—Permit Required Before Work Begins

The Perry County Health Department oversees the Private Water Program and requires a Private Well Permit before you develop, alter, or deepen any private water well. This is mandatory and must be obtained *before* drilling or installation.

The permit process requires you to submit well design information (typically prepared by a licensed well contractor) that includes casing depth, setbacks from the septic system and property lines, planned water use, and location. The Health Department reviews this against state water quality and construction standards. Once approved, you receive a permit that allows you to proceed with drilling. After installation, the Health Department may require water quality testing (bacteriological and chemical) to ensure the well meets safe drinking water standards.

Indiana's groundwater law is based on the reasonable use doctrine, meaning you have the right to use groundwater for reasonable domestic and agricultural purposes, but the county health department must approve your specific well. If your property is near a municipal water service area, there may be additional state-level restrictions, but that is less common in rural Perry County. Contact the Health Department and ask: *What is the permit application process for a private well in Perry County? Are there setback requirements from septic systems, property lines, or surface water? Are water quality tests required before or after installation?* Provide them with your intended well location and septic system location if you have already permitted the septic; they will flag any conflicts.

Utility Disconnection: Unclear—Direct Contact Required

Perry County does not publish specific regulations on disconnecting from utilities (electricity, natural gas, or municipal water). At the state level, Indiana has no law requiring electrical grid connection, and solar installations do not increase property tax assessment. However, some local occupancy permits may require utility hookups, and enforcement varies by county and municipality.

The primary state-level obstacle to full utility disconnection in Indiana is the 300-foot municipal sewer rule: if your property is within 300 feet of an active municipal sewer line, the municipality can require you to connect, even if you already have a legal septic system. In rural Perry County, this is less likely to be an issue, but you should ask the Planning and Zoning Department when you confirm zoning: *If I use a private septic system and private well, is there any county or municipal requirement that I connect to electrical service? Is there any occupancy permit condition that requires utility hookups?* Get the answer in writing if possible. This will inform your energy plan (grid-tied solar, off-grid battery bank, hybrid system) and your budget.

Practical Next Steps: The Confirmation Sequence

If you own or are considering raw land in Perry County for off-grid living, here is the sequence I recommend:

1. Call the Planning and Zoning Department first. Ask about zoning eligibility for off-grid use, lot size requirements, and any conditional use permits you might need. Confirm the dwelling type you are considering (site-built home, tiny home, RV) is permitted. Get the contact name and date.

2. Call the Health Department. Ask about septic permit requirements, private well permit requirements, and any local rules on composting toilets, greywater, or rainwater. Ask whether state rules apply if the county has no specific rule. Ask about the 300-foot sewer rule if your property might be near municipal service.

3. Hire a licensed septic designer and well contractor. They will help you evaluate the site for septic feasibility (soil type, groundwater depth, setbacks) and prepare designs for permit submission.

4. Submit septic and well permits to the Health Department. These are the rate-limiting steps. Approval typically takes 2–4 weeks but can be longer if revisions are needed.

5. Submit the Improvement Location Permit and building permit to Planning and Zoning with septic approval attached.

The entire process from first phone call to building permit can take 8–12 weeks or longer, depending on permit review timelines and whether revisions are required. Do not assume the county will approve your plan quickly; budget time for back-and-forth with the Health Department and Planning and Zoning.

Final Note on Unconfirmed Areas

Several areas—zoning for off-grid use, dwelling type flexibility, greywater reuse, rainwater harvesting, and utility disconnection—are not documented in county publications and require direct contact with county departments to answer. This is not a dead end; it simply means the county has not codified rules in accessible form. When you call, ask for written confirmation of the answer or ask the staff member to email you a summary. This will protect you if you later have a dispute with the county or if staffing changes. Off-grid living in Perry County is feasible, but clarity requires direct inquiry.
