Off-Grid Living in Daviess County, Indiana
Daviess County, Indiana has countywide zoning and its own local septic ordinance layered on the state rule, so off-grid plans need county (or City of Washington) sign-off on dwellings and septic. Greywater, rainwater, and mandatory-hookup rules aren't clearly addressed locally, so those need a direct call to confirm.
Is it legal to live off-grid in Daviess County, Indiana?
There is no outright ban on living off-grid in Daviess County, Indiana - it is legal but regulated. Zoning and land use are restricted, putting a cabin, tiny home, or RV on raw land is set locally and vary by area, and building permits are generally allowed. Plan around septic/wastewater (generally allowed) and disconnecting from utilities (not clearly documented online, so confirm it locally). Because these rules are set locally, confirm the specifics with Daviess County before you buy land or build.

I've been digging into what off-grid living actually looks like county by county, and Daviess County, Indiana is a good example of a place that surprises people: it's rural, it's agricultural, but it is NOT a "no zoning" free-for-all like some Indiana counties. Daviess County has countywide zoning administered by the Advisory Plan Commission (APC), with a Board of Zoning Appeals handling variances, and a Building & Compliance Department issuing permits. If you're inside the City of Washington or its two-mile fringe, the City's own Building Commission takes over instead of the county, though notably the same person (the Plan Director) wears both hats.
Zoning and raw land: the county zoning ordinance governs what you can do with land and what counts as a dwelling. I'd call the Plan Director's office before buying land if your plan is unconventional.
Dwellings, tiny homes, RVs: the ordinance defines a "Dwelling Unit" fairly broadly (living space intended for year-round occupancy with sleeping, cooking, and sanitary facilities), and mobile homes only qualify if the wheels and axle are removed. I could not confirm any specific tiny-home minimum size rule or how RVs-as-permanent-residences are treated. That's a direct-call question to the Plan Director.
Building permits: required countywide through Building & Compliance, or through the City of Washington Building Commission if you're inside city limits or the fringe.
Septic: Daviess County has its own local septic ordinance (Septic Ordinance 2023-3, per the county's own page) layered on top of the state's onsite sewage rule, and the county Health Department's Environmental Health Services staff handle applications. Composting toilets aren't separately addressed in what I found, so that's worth a direct call.
Greywater and rainwater: I found no county-specific rules on either. Greywater likely falls under the same septic/onsite sewage oversight in practice, but that's my inference, not a confirmed rule. Rainwater harvesting appears unregulated locally, inheriting the general state baseline of no prohibition.
Wells: no county ordinance restricting private wells turned up; well construction is a state (DNR/licensed driller) matter. If you'd rather skip a private well, Daviess County Rural Water serves the area with piped water, though that's a private utility choice, not a legal requirement.
Off-grid utilities generally: I found no countywide ordinance mandating hookup to electric, water, or sewer. That said, your septic and dwelling-unit permits (see above) could functionally require an approved sewage system even if you skip grid power and water. Confirm this directly with Building & Compliance and the Health Department before you commit to a fully disconnected setup.
Bottom line: Daviess County is workable for off-grid living but it's a "check first" county, not a "wide open" one, thanks to countywide zoning and a local septic ordinance stacked on the state rule.

Planning a build in Daviess County
The rules above decide what you may build. The numbers below decide what you will have to build, and they come from this place rather than from a national average.
Solar: size for the worst month, not the average
Daviess County averages 4.7 peak sun hours a day across the year, but its worst month averages 2.8. That is a drop of about 41 percent. An array sized on the annual figure will therefore come up short in the worst month by roughly that much, in the season when lights, pumps, and heating fans all run hardest.
Put another way, meeting the same daily load in the worst month here takes about 1.7 times the array that the annual average implies, or a generator and the fuel budget to run it. Neither is wrong; what is wrong is discovering the gap in the first winter. The solar calculator runs this arithmetic against your own load list, and lesson four covers building that list before buying panels.
Heat: 5,185 heating degree days
That is a cold-climate heating season, where the fuel supply is a year-round job and a second heat source earns its keep. Heating demand at this level dwarfs everything electrical in the house, which is why almost nobody here heats with electricity from a battery bank.
As a rough order of magnitude, a small, reasonably insulated cabin heated mainly with wood in a climate like this tends to burn in the region of 4.3 cords a season, with the real figure swinging widely on insulation, house size, and how you burn. Treat that as a bracket for planning your woodshed rather than a promise, split and stack a season ahead, and check with a moisture meter before burning. The firewood calculator and heat-loss calculator narrow it down from your own building.
Growing season: about 202 frost-free days
Average last frost falls around 04-09 and average first frost around 10-28, which leaves roughly 202 days between them. That figure decides what can be grown outdoors without protection, whether a season extension structure is worth building, and how much of the year food storage has to cover. Averages also hide the frost that arrives two weeks early, so plan the garden on the short end. The garden calculator and food storage calculator work from this number.
Water: what the roof would actually catch
Daviess County receives about 45.7 inches of precipitation a year. A 1,000 square foot roof here would shed on the order of 24,216 gallons a year at a realistic 85 percent collection efficiency, before any losses to first-flush diversion, evaporation, or overflow in a heavy storm.
The annual total is the easy part. What sizes a cistern is the longest dry stretch, because catchment is seasonal almost everywhere and a tank that covers the average year can still run empty in August. Check the local rules too: rainwater harvesting is regulated in some states even where it is broadly allowed. The rainwater calculator works from your own roof and rainfall pattern, and lesson three covers why water is chosen before power.
Snow: 15 inches in an average year
At this level, snow is a design input rather than a nuisance. It sets the roof load your structure has to carry, it decides where a metal roof may safely shed and therefore where doors, propane tanks, and walkways must not be, and it buries a ground-mounted array at exactly the time of year the array matters most. It also makes the driveway a system: how it is graded, where the snow is pushed, and who clears it when you cannot.
Distance is part of the plan
Measured straight line from the center of Daviess County: the nearest fire station is about 13.6 miles away (Bloomfield Fire Department), the nearest hospital is about 13.9 miles away (Greene County General Hospital), the nearest supermarket is about 5.5 miles away (Dutch Pantry). Road miles will be longer, and in winter longer again.
The fire distance is worth noting before you buy rather than at renewal: insurers commonly rate rural property partly on how far it is from a responding station and from a water source, and some decline off-grid or owner-built structures outright. Ask an agent who writes rural policies what they would need to see, while the answer can still change what you build. Lesson eleven covers the insurance and financing side.
The hospital distance sets what your first aid kit and your medical plan have to cover in the gap, and it is the number to think about before anyone in the household depends on refrigerated medication or mains-powered equipment.
Confirming this for your own parcel
On this page 4 of the eight topics are recorded as unclear or as varying within Daviess County: what counts as a dwelling, greywater, rainwater harvesting, mandatory utility connection. Those are the calls to make first, because they are the ones where a general answer cannot be trusted for a specific parcel. Ask for the answer in writing where the office will give it, and note the name and the date where it will not.
Where a topic is recorded as settled here (zoning, building permits and codes, septic and sewage, wells and water rights), the source is cited further down this page. Sources go stale, ordinances get amended, and this site logs corrections publicly rather than editing them away, so if you find something here that no longer matches the county, the corrections page is how to say so.
Before any of those calls, walk the parcel with the land walk checklist and take the questions for the county with you. The parcel check pulls flood, wetland, slope, and access data for a specific parcel and shows its sources, which is a good way to arrive at the office with the questions already framed. Lesson two is the wider version of this list.

FAQ
Common questions about off-grid living in Daviess County
Is it legal to live off-grid in Daviess County, Indiana?
There is no outright ban on living off-grid in Daviess County, Indiana - it is legal but regulated. Zoning and land use are restricted, putting a cabin, tiny home, or RV on raw land is set locally and vary by area, and building permits are generally allowed. Plan around septic/wastewater (generally allowed) and disconnecting from utilities (not clearly documented online, so confirm it locally). Because these rules are set locally, confirm the specifics with Daviess County before you buy land or build.
Does Daviess County have zoning?
Yes. Unlike some rural Indiana counties, Daviess County has countywide zoning administered by the Advisory Plan Commission, so land use and dwelling rules are enforced here, not left unregulated.
Can I put a tiny home or RV on my land as a permanent residence?
Not clearly confirmed. The county ordinance defines dwellings broadly and treats mobile homes as dwellings only if wheels and axle are removed, but tiny-home and RV specifics aren't spelled out in what I found, so call the Plan Director's office.
Do I need a permit for a septic system?
Yes. Daviess County has its own septic ordinance on top of the state rule, administered through the county Health Department's Environmental Health Services.
Is rainwater harvesting or greywater reuse regulated?
I found no county-specific rules for either. Rainwater appears to follow the general state baseline of no prohibition, and greywater likely falls under the same septic oversight as other wastewater, but neither is officially confirmed for Daviess County.
Am I required to hook up to grid electric or water?
No countywide mandatory-hookup ordinance was found, but septic and dwelling permitting requirements could still require an approved sewage system. Confirm with Building & Compliance and the Health Department before finalizing an off-grid setup.
