Off-Grid Living in DeKalb County, Indiana

I researched DeKalb County's off-grid framework by reviewing the county Unified Development Ordinance, Health Department documentation, building permit procedures, and the statewide Indiana rules that operate here. This is a moderately regulated county, and the pathway to off-grid living is real but requires early coordination and sequential approvals. Here's what I found—and how to move forward.

Zoning and Land Use: You Must Confirm Your Zone First

DeKalb County is not a no-zoning county. Unlike much of rural Indiana, the county enforces a Unified Development Ordinance that applies countywide to all unincorporated areas *and* the Town of Corunna. This means you cannot buy raw land and build as you wish. Your parcel has a designated zoning classification, and off-grid dwelling must be a permitted use in that zone.

The practical implication: Before signing a purchase agreement, call the DeKalb County Planning Office at (260) 920-1488 and ask for your parcel's zoning classification by legal description or address. Request a copy of the permitted uses for that zone. Off-grid living—if permitted at all—may be classified as a single-family dwelling (typically allowed in residential and agricultural zones) or it may require a conditional use permit or variance. Do not assume agricultural land allows off-grid residences without confirmation. The planning office can tell you whether your intended use is by-right, conditional, or forbidden. If it requires a variance or conditional use, budget time and possibly legal or consultant fees for that process.

Single-Family Dwellings and Non-Standard Structures: Indiana State Law Applies, But Confirm County Detail

Indiana state law permits single-family dwellings and accessory structures. DeKalb County follows this baseline but may have additional requirements for non-standard dwellings—tiny homes, log cabins, or modular structures. I did not find county-specific ordinance text addressing tiny homes or their dimensional or construction standards. This is a gap I recommend you close before design.

Contact the DeKalb County Planning Office and the Building Department at (260) 920-1488 and ask: (1) Does the county accept tiny homes on permanent foundations under the state's "Log Cabin Rule" (IC 36-7-8-3(d))? (2) What are the minimum square footage or lot coverage requirements for a residential dwelling in your zone? (3) Are manufactured or modular homes subject to different approval paths? (4) If you plan an accessory dwelling unit (ADU) or guest cottage, what are the setback and size limits? Tiny homes on wheels cannot be used as permanent residences outside mobile home parks under Indiana law, so if that is your vision, stop here—DeKalb County will not permit it.

Building Permits and Pre-Permit Approvals: A Sequential Gauntlet

This is critical: DeKalb County will not issue a building permit until you have obtained a well permit and a septic permit from the DeKalb County Health Department. This is stricter than Indiana's baseline state requirement and gives the Health Department veto power over your water and waste systems. Plan for this.

Here is the realistic sequence:

1. Confirm zoning compliance (as above). 2. Determine your site's water and waste constraints. Is the property within 300 feet of a municipal sewer line? If yes, the municipality can require you to connect to it, even if you have a legal septic system. DeKalb County has several municipalities with public water and sewer, so check your address against municipal service maps at the county website or by calling the relevant town clerk. 3. Contact the DeKalb County Health Department at (260) 920-1181. Describe your property (location, lot size, soil type if known, water table conditions if known) and your intended systems: private well, septic system, and any greywater or rainwater system you plan. Ask whether a site evaluation is required before you submit permits. Many counties require a site inspection or soil boring test; DeKalb County may do so, and you need to know this upfront. 4. Submit a well permit application to the Health Department. You must have this permit in hand before applying for a building permit. The Health Department will review the proposed well location (typically 50+ feet from septic systems, property lines, and contaminants), construction method, casing depth, and arrangements for water quality testing. Indiana's groundwater rules are administered by the county health department in consultation with the state, and DeKalb County enforces these. Expect 2–4 weeks for review. 5. Submit a septic system permit application (or on-site sewage disposal permit) to the Health Department's Septic Division. You will need to provide site plans, soil descriptions, proposed tank and drain field locations, and the name of a registered installer (see below). The Health Department licenses and inspects all installers. Expect 2–4 weeks. 6. Once both permits are approved, you can submit your building permit application to the DeKalb County Building Department, along with copies of the well and septic approvals.

This sequencing matters. Do not pour money into design or land purchase without confirming that the Health Department will approve your water and waste approach. If they reject your proposed well location or septic field size, redesign comes next.

Septic Systems and On-Site Waste Disposal: Permitted but Regulated

On-site septic systems are permitted under Indiana law and DeKalb County's Health Department oversees them. All septic system installers must be registered with the Health Department; you cannot hire an unregistered contractor. The county's Septic Division licenses, approves, and inspects systems.

A practical note: I did not find evidence that composting toilets, vault toilets, or other alternative waste systems are approved as *primary* systems in DeKalb County. They may be permitted as *auxiliary* systems (e.g., in a guest cabin or outbuilding not occupied year-round), but I cannot confirm this without direct contact with the Health Department. If you are considering an alternative toilet to reduce water use or septic burden, call the Health Department at (260) 920-1181 and ask specifically: "Is a [specify the system, e.g., composting toilet, incinerating toilet, vault toilet] acceptable as a primary waste disposal system for a permanent residence?" Have the answer in writing before you commit to it. If the answer is no, you will install a conventional septic system.

Wells and Private Water Supply: Early Approval Required

DeKalb County requires a well permit from the Health Department before you apply for a building permit. This exceeds Indiana's state baseline (which only requires ISDH notification) and means the county has discretionary approval authority over your water source.

Here is what to expect: The Health Department will review your proposed well location (distance from septic fields, property lines, and known contaminants), the construction method (typically a drilled well with steel casing to a minimum depth), and water quality testing arrangements. Indiana's reasonable use groundwater doctrine applies, so you can use water for domestic and agricultural purposes on your own property, but the Health Department will confirm that the well does not harm a neighbor's water supply or violate local aquifer rules.

Before you apply, contact the Health Department and ask: (1) What is the minimum well casing depth for your property? (2) How far must the well be from the septic drain field and from property lines? (3) Will the Health Department require a water quality test before issuing the permit? (4) Are there any known aquifer or groundwater quality issues in your area (e.g., nitrate contamination, hard water, or low yield)? Get these answers before you hire a well driller. A well in the wrong location will be rejected and must be relocated at your expense.

Greywater Reuse: Unconfirmed Locally—Confirm Now

I found no county-specific ordinance permitting or prohibiting greywater reuse. Indiana state law does not explicitly prohibit residential greywater reuse, but the state Residential Code defers to county health departments for approval. This means DeKalb County Health Department has discretion.

If you plan to reuse greywater (from sinks, showers, laundry) for irrigation or toilet flushing, contact the Health Department at (260) 920-1181 and describe your system in detail: *Where will the greywater come from? How will it be treated (filtration, UV, settling, etc.)? Where will it be reused (landscape irrigation, toilet flushing, etc.)? What storage volume?* The Health Department will tell you whether your system is acceptable as part of the building permit review. Do not assume it will be approved. If approval is uncertain, plan a conventional septic system as your backup.

Rainwater Harvesting: Permitted, But Confirm Large-Scale Plans

Indiana state law does not restrict rainwater harvesting, and the 2020 Indiana Residential Code includes guidance for residential collection systems. DeKalb County has not imposed a county-specific restriction that I found. However, this does not mean unlimited harvesting is permitted locally.

If you plan a modest rainwater system (rooftop gutters to a cistern for garden irrigation or toilet flushing), you likely need no permit and can proceed quietly. However, if you plan a large-scale system (multiple roof areas, large storage tanks, treatment equipment, or year-round domestic use), contact the DeKalb County Health Department to confirm that it does not trigger building permit review or septic system modifications. Also note: rainwater cannot be used for public potable use in Indiana, only for domestic and agricultural use on your own property. If your intent is to eliminate reliance on a private well by using rainwater alone, you'll need to discuss water supply adequacy with the Health Department—they may require a backup water source or minimum well capacity.

Utilities and Grid Disconnection: Permitted with One Major Exception

Indiana permits disconnection from the electrical grid. There is no DeKalb County ordinance requiring you to remain connected to power, and solar installations do not increase your home's assessed property value for tax purposes.

However, the 300-foot municipal sewer rule is a significant constraint: If your property is within 300 feet of a municipal sewer line, the municipality can *require* you to connect to it, even if you already have a legal septic system. This means if you are near any incorporated town (such as Corunna, Ashley, or Butler), confirm the municipal sewer service boundary before you finalize your property purchase. Call the relevant town clerk and ask: "Is my address within the municipal sewer service area or the 300-foot impact zone?" If yes, you may be forced to connect, which undermines off-grid planning.

Electrical grid disconnection is straightforward: notify the utility, arrange a final meter read, and proceed with solar or other onsite generation. Natural gas disconnection is also simple if your property is served by gas. Water utility disconnection requires the Health Department's approval of your private well. Ensure all approvals are in writing before you disconnect.

The Review Process: Start Early, Get It in Writing

The realistic timeline for off-grid approval in DeKalb County is 8–12 weeks if there are no complications:

• Week 1–2: Zoning confirmation, municipal service boundary check.
• Week 2–4: Health Department site evaluation (if required) and initial permit applications.
• Week 4–8: Health Department reviews well and septic applications.
• Week 8–10: County Building Department issues building permit (pending Health Department approvals).
• Week 10–12: Construction begins.

Delays occur if the site evaluation reveals unsuitable soils, if the well location conflicts with the septic field, or if the Health Department requests additional information. Budget extra time and maintain close contact with the Health Department. Email or obtain written responses to critical questions; do not rely on phone conversations alone.
