Off-Grid Living in Pulaski County, Missouri

Pulaski County, Missouri is a tricky one to research because the county itself doesn't run much of a public-facing planning or zoning presence. I want to be upfront about that gap rather than paper over it with guesses.

Zoning. I could not find an official Pulaski County zoning ordinance page. Missouri counties only have zoning authority if the county commission has formally adopted it under state law (RSMo Chapter 64), and nothing I found confirms Pulaski County has done so for unincorporated land. If you're eyeing raw land outside city limits, call the County Commission or Clerk directly and ask point-blank whether zoning applies to your parcel.

Dwellings, tiny homes, RVs. Same story, no county-specific rule found. If your land is inside Waynesville or St. Robert city limits, those municipalities may have their own codes on minimum house size or RV living that would override whatever the county baseline is.

Building permits. A permit-lookup aggregator (not an official government source, so take it as a lead rather than confirmation) points to a building department serving St. Robert. I found no official Pulaski County page confirming code enforcement in unincorporated areas. Missouri has no statewide building code, so this really is locality by locality; check with the relevant city hall or the county directly.

Septic and composting toilets. This is the one area where Pulaski County is clearly on record. The Pulaski County Commissioners adopted an On-Site Wastewater Treatment Systems (OWTS) ordinance back in 2007, and the Pulaski County Health Center administers it. That sits on top of Missouri DHSS's statewide minimum standards for new systems and major repairs. Composting toilets aren't separately addressed anywhere I found, so I'd assume the Health Center folds them into the same OWTS review until told otherwise.

Greywater. Nothing on the books at county or state level that I could confirm. Ask the Health Center, since any oversight would likely run through their OWTS program.

Rainwater harvesting. No county restriction turned up in this research, and Missouri's general legal posture protects collecting rainwater on your own property.

Wells. Well drilling is governed statewide by Missouri DNR under the Water Well Drillers Act, and I found no separate Pulaski County well ordinance. The county also has multiple Public Water Supply Districts, so depending on where your land sits you may be inside one of those service areas, which matters for whether you're required to hook up versus drill your own well.

Utilities. No source shows Pulaski County prohibiting off-grid living or disconnecting from utilities. Your real obligations are the septic/OWTS permit and, if you want a well, the DNR well construction permit.

Bottom line: this county's septic rules are real and enforced locally, everything else leans on state defaults or is simply unconfirmed, so a phone call to the Commission and the Health Center before you buy land will save you headaches.
