The fire-district question, asked by name

Building-code authority in Missouri is not only a county matter. RSMo 321.220(12) lets a fire protection district board adopt ordinances whose administrative standards are "industrial codes adopted by nationally organized and recognized trade bodies", and makes a violation a misdemeanor prosecuted by the county prosecutor — and classification has nothing to do with it. But RSMo 321.228, effective 28 August 2012, cuts that off wherever a city, town, village or county "adopts or has adopted, implements, and enforces a residential construction regulatory system": inside such a jurisdiction, districts wholly or partly within it are "without power, authority, or privilege to enforce or implement" one, and anything they have adopted "shall be treated as advisory only". So inside Waynesville and St. Robert, which plainly do both, the districts are preempted. They keep final say on fire hydrant location and specification, hydrant flow rates and fire lanes; they may inspect the alteration, enlargement, replacement or repair of a one- or two-family dwelling, though not new construction; and they may not charge a fee for either. Outside the cities, where the county regulates nothing, that door is open. The Waynesville Rural Fire Protection District has been asked by name: the only permit it publishes is a free open-burn permit for vegetative waste, obtainable by telephone or on a printed form, and its inspections page carries no adopted code. Note also that RSMo 321.220(12) bars a district from requiring a permit for the erection, maintenance, repair, alteration or extension of a farm building at all.

RSMo 321.228 (effective 28 Aug 2012) and RSMo 321.220 (effective 28 Aug 2025), both rendered from revisor.mo.gov and read in full 8 Sep 2026, each carrying the Title XXI / Chapter 321 heading and an Effective line that the host's bogus-section interstitial does not; Waynesville Rural Fire Protection District, wrfpdmo.org permit and inspections pages, read 8 Sep 2026 (a bogus path on that host returns an honest HTTP 404 titled "File Not Found"); Pulaski County NG9-1-1, Other Agency Sites index, pulaskimo911.org, read 8 Sep 2026, which lists the Waynesville Rural, Crocker Rural, Dixon Rural, Tri-County and Hazelgreen fire protection districts along with the St. Robert and Fort Leonard Wood fire departments

The ground: chert and a fragipan, not shallow rock

The reflex about Ozark counties is bedrock near the surface, and the soil survey does not support it here. Across the 352,883 acres of survey area MO169, lithic and paralithic bedrock is mapped within 51 centimetres — about twenty inches — on 4,419 component-weighted acres, roughly 1.3 per cent, and within 102 centimetres on 18,084 acres, about 5 per cent. What actually governs a footing here is different. A fragipan is mapped on 84,298 component-weighted acres, close to a quarter of the survey, at depths between 41 and 97 centimetres — 16 to 38 inches — which is the band a 24-inch footing lands in; the Union soils carry theirs at 76 centimetres and the Viraton soils at 53. The dominant component is Clarksville at 73,818 component-weighted acres, with chert fragments running from nothing to 58 per cent by volume through its horizons, and the single largest map unit in the county is Clarksville-Gepp complex, 15 to 35 per cent slopes, stony, at 71,125 acres. Map units whose slope class begins at 15 per cent cover 142,018 acres, about 40 per cent of the survey. Karst is real but modest: the Department of Natural Resources sinkhole layer returns 138 mapped sinkholes inside the county boundary, against 247 in Phelps next door and 1,471 in Greene.

USDA-NRCS Soil Data Access, sdmdataaccess.nrcs.usda.gov Tabular REST endpoint, survey area MO169 (Pulaski County, Missouri — the legend table also returns Pulaski survey areas in six other states, and only MO169 is this county), queried 8 Sep 2026; depth values come from corestrictions.resdept_r, which is recorded in CENTIMETRES, converted here at 51 cm ≈ 20 in and 102 cm ≈ 40 in, with restricted acres computed as mapunit.muacres × component.comppct_r ÷ 100 against the survey's total mapped acres. A bogus area symbol returns an empty table on that host and an invalid column name returns an explicit ServiceException. Missouri Department of Natural Resources sinkhole layer, gis.dnr.mo.gov/host/rest/services/geology/sinkholes/MapServer layer 1, intersected with the U.S. Census TIGERweb county polygon for GEOID 29169, queried 8 Sep 2026: statewide control 16,001 points, matching the department's published figure of approximately 16,000, with Greene 1,471 and Camden 91 reproducing recorded values exactly and a deliberately impossible object id returning zero.

What the cities charge, and what the trades have to hold

There is no statewide general-contractor licence in Missouri, so the answer is municipal and it differs city to city inside this county. St. Robert requires a city licence before anyone engages in construction, in twelve classifications beginning with General Contractors and running through electricians, plumbers, mechanical, concrete, roofing, masonry, asphalt, landscaping, remodeling, carpentry and fencing; the fee is $25 on first application and $5 to renew each January, and a subcontractor working under a licensed general contractor on that contractor's project does not need a separate licence. Waynesville licenses a General Contractor at $150 a year under its business-licence schedule and states that any subcontractor working for that business will be licensed through the city. On permits, Waynesville's codified fee schedule charges $0.10 per square foot for one- and two-family dwellings with a $150 minimum, measured on gross floor area inside the exterior walls and excluding unfinished basements and garages, plus $50 for a residential room addition, garage or retaining wall and $25 for a shed, deck, fence or gazebo; re-inspection of uncorrected work costs $25, and re-inspection of a dwelling occupied without approval costs $100. Dixon's 2024 general build permit application charges $100 for new construction, $25 for a garage, carport, shed, deck or remodel, and $250 each for a water tap and a sewer tap, and requires structures to stand at least 25 feet from the roadway and 10 feet from any side or boundary line. Waynesville also levies utility impact fees under § 615.025: $150 for a residential sanitary sewer connection inside the city, and $1,500 for a customer outside the city limits plus any applicable Pulaski County Sewer District fees.

Where the land is, and how much of it there is

The 2022 Census of Agriculture counts 423 farms in Pulaski County across 117,115 acres, at an average of 277 acres, and splits that land into 39,965 acres of pastureland, 33,586 of woodland, 22,741 of cropland and 20,823 of other uses. Against the county's 547.112 square miles of land area, that is a county where farm ground is real but not dominant, which is the practical signature of a place with a 67,180-acre federal installation and a mostly wooded, sloping remainder. The population is unusually concentrated outside the incorporated places: 39,283 of the county's 53,964 residents live in the unincorporated balance, against 5,511 in St. Robert, 5,493 in Waynesville, 1,547 in the Pulaski County portion of Richland, 1,215 in Dixon and 915 in Crocker. Richland is a three-county town — 1,547 of its 1,729 residents are in Pulaski, 106 in Camden and 76 in Laclede — so a Richland address does not by itself tell you which county's rules apply. The regional planning commission names Buckhorn, Devil's Elbow, Hayden, Laquey and Swedeborg as the county's unincorporated communities, and those are the places where a barndominium is being built outside anybody's zoning map.

Waynesville's A-1 district is where an acre still buys a house

Inside the city limits, Waynesville's A-1 Agricultural District permits single-family dwellings on a minimum of one acre of ground even where they are "not connected to agricultural operations", alongside farming, pasturing of livestock other than hogs and swine, roadside stands for produce grown on the premises, and accessory buildings customarily incidental to those uses including repair shops, sheds, garages, barns and silos. The area regulations are a 43,560-square-foot minimum lot, a 150-foot minimum lot width, 50-foot front and rear yards and 15-foot side yards, with buildings held to two and a half storeys or 35 feet above average finished grade. Those are the numbers that apply to a house-and-shop build on the agricultural edge of the county's largest city, and they are noticeably more generous on lot size and noticeably tighter on setbacks than the R-1 district's 7,500-square-foot minimum and 8-foot side yards.
