Zoning, building permits and septic rules in Decatur, Arkansas

Decatur is a city in Benton County, Arkansas. Decatur adopts its own zoning, so inside its limits Decatur’s rules apply, not the county’s. Septic permits inside Decatur come from the state health agency. 3 rules below are quoted from official sources and independently re-checked, most recently on November 1, 2026. Rules for unincorporated land are on the Benton County page.

Answers from the rulebook for Decatur

Decatur’s own rules

  • Local zoningPresent (with conditions)

    Land inside Decatur city limits (Decatur, AR 72722, Benton County). Not the unincorporated county area.

    • The official planning page says the city's planning and inspection department enforces zoning regulations. The zoning ordinance text, its districts and its dimensional limits were not located on an official page.
    • The city's code compliance page says a link to the ordinances will be added soon, so the adopted zoning text was not reviewable online.
    “the city of decatur's planning & inspection department is responsible for the following: enforcing building codes enforcing zoning regulations administering ordinances for permits and inspections”
  • Permit processPartial

    Building permit process inside Decatur city limits, administered by the city Planning & Inspections department

    • Only the department's responsibility is stated; the application steps, forms and submittal list were not published on the pages opened.
    • Contact Decatur City Hall at 479-752-3912.

Rules another office applies inside Decatur

Decatur does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.

  • Who permits septicState (with conditions)

    Onsite wastewater (septic) systems on land inside Decatur city limits (Benton County)

    • The Arkansas Department of Health sets statewide onsite wastewater policy; local environmental specialists in each local health unit carry out the review, as the ADH page states.
    • Systems of 1,500 gallons per day or more are reviewed by the state Division of Environmental Quality, per the same ADH page.
    • Whether a parcel may use septic rather than city sewer depends on sewer availability, which was not established.
    • No Decatur-specific or Benton County health unit page confirming local septic administration was located.

    onsite system design flow threshold for ADH permit review: < 1500 gpd (systems 1500 gpd and larger reviewed by Division of Environmental Quality)

    “the arkansas department of health's onsite wastewater program sets statewide policies and provides assistance to environmental health specialists in each of the local health units.”

Unanswered questions are usually a sign that Decatur publishes no rule on the point, not that none exists. Benton County’s page lists the county offices to call.
