Off-Grid Living in Dickson County, Tennessee

If you're eyeing a piece of land in Dickson County, Tennessee for an off-grid setup, the first thing I want you to understand is that "Dickson County" isn't one single rulebook. There's the unincorporated county, governed by the Dickson County Planning Commission's Zoning Resolution, and then there are several incorporated towns (City of Dickson, Burns, Charlotte, Vanleer, White Bluff, Slayden) that each run their own zoning and building codes. Everything below is about the unincorporated county unless I say otherwise, and if you're looking at a parcel inside one of those towns, especially the City of Dickson, expect a stricter, more detailed code to apply instead.

Zoning in unincorporated Dickson County isn't absent, the county has an adopted Zoning Resolution and separate Subdivision Regulations, administered by the Planning Commission, with the County Commission holding override authority under state law. That's a step beyond the "no zoning at all" reputation some rural Tennessee counties have, so don't assume you can do anything you want on raw land here, check with the Planning Commission first.

For dwellings, I couldn't confirm a county-specific rule on tiny homes, Appendix Q, or RV living. Tennessee's state building code baseline (built on the IRC) likely applies unless the county has opted out, but I don't have confirmation of that opt-out status. This is a call-and-ask situation with the Planning Commission or county building authority.

On permits, I found solid info for the City of Dickson (permits and inspections run through the Planning and Zoning Department), but for unincorporated county land, I could not confirm which office issues building permits or which code edition is enforced. Don't assume either way; ask directly.

Septic systems fall under Tennessee's state framework administered by TDEC, though some counties handle septic through a local health department under contract with the state. I could not confirm whether Dickson County is one of those "contract counties" or relies on a TDEC regional field office. Either way, a septic permit will be required for a new system; start with TDEC's regional contacts.

Greywater reuse has no county-specific ordinance that I found, so it falls back on the state plumbing code baseline, which I'd call restrictive by default until you get specifics from the state. Rainwater harvesting looks fine, no county restriction turned up, and Tennessee doesn't restrict collection statewide either.

Private wells are governed by the state's Water Well Act, requiring a licensed driller, and the Water Authority of Dickson County (WADC) only serves customers within its own piped-water service area, it has no jurisdiction over private wells elsewhere. Finally, on disconnecting entirely from utilities, I didn't find a county ordinance mandating hookup to water or sewer, but some Tennessee towns do have mandatory-connection rules, so check with WADC and the relevant town hall for your exact parcel.

Bottom line: Dickson County has more structure than a totally unzoned rural county, but a lot of the fine print on dwellings, permits, and septic administration isn't nailed down in public documents I could find. Phone calls to the Planning Commission and TDEC will save you a lot of guessing.
