Sullivan is a small non-charter municipality in Crawford County, population ≈ 6,200. Above the 5,000 Art. VI §19 charter-eligibility threshold but operates as a fourth-class (Chapter 79) city. Code structure is standard Euclidean with R-1 through R-3 residential, C-1/C-2 commercial, I-1 industrial. Most dimensional values in v1 are marked 'inferred' (c=i) — typical small-city low-density guesses calibrated to peer Missouri municipalities of comparable size.

Worth knowing
  • Small town context (pop. ~6,200) with simplified zoning structure
  • Historic downtown preservation focus with design review overlay authority
  • Two-tier residential gradient (R-1/R-2 single-family + R-3 multi-family) without state preemption requirements

State preemptions

MO RSMo Chapter 89 (Zoning and Planning)applies
Qualifying condition
RSMo Chapter 89 §§89.020-89.110 (Standard State Zoning Enabling Act derivative). Fourth-class city under RSMo Chapter 79 (population ≈ 6,200; technically eligible for charter consideration under Art. VI §19 at >5,000 population but not yet chartered as of available record). Zoning authority derives from Chapter 89 (universal enabling for MO municipalities) layered with home-rule authority where applicable. Citation-date 1939 is a conservative codification-start estimate; Chapter 89 has been continuously in force throughout the modern MO zoning regime.
Effect
Zoning ordinance must comply with §89.040 'in accordance with a comprehensive plan' standard and §89.050 procedural floor (15-day published notice, public hearing, two-thirds supermajority on protest petition). Rezonings subject to §89.060 protest petition (30% area / 30% within 185 ft).
MO RSMo §89.020.2 (manufactured-home appearance preemption)applies
Qualifying condition
RSMo §89.020.2 enacted via SB 644 (2006) — citation flagged for re-verification in preemptions.md retrieval-issues. Permissive preemption: applies to all MO municipalities including Fourth-class city under RSMo Chapter 79 (population ≈ 6,200; technically eligible for charter consideration under Art. VI §19 at >5,000 population but not yet chartered as of available record). City may adopt reasonable appearance criteria (foundation, pitch, width) for HUD-Code manufactured homes in single-family districts but is not compelled to permit them universally. Status per_parcel_conditional because effective constraint depends on whether the city permits manufactured homes in any single-family district at all.
Effect
If the city permits manufactured homes in any single-family residential district, it may impose reasonable appearance criteria. The city may also lawfully not permit HUD-Code manufactured homes outside designated MH districts so long as zoning is not internally discriminatory.
MO RSMo §700.027 (modular-unit state code equivalence)applies
Qualifying condition
RSMo §700.027 — Statewide modular-unit state code; equivalence with site-built. Applies to all MO municipalities. Citation-date 1986 is a conservative estimate for chapter codification — re-verify against revisor.mo.gov for exact enacting session law.
Effect
Modular units (built to MO state code) are treated as equivalent to site-built dwellings; cannot be excluded from districts that permit site-built dwellings of the same type.
MO Hancock Amendment — Mo. Const. Art. X §§16–24applies
Qualifying condition
Mo. Const. Art. X §§16–24 (Hancock Amendment; 1980 voter initiative). Statewide constitutional limit. Applies to Fourth-class city under RSMo Chapter 79 (population ≈ 6,200; technically eligible for charter consideration under Art. VI §19 at >5,000 population but not yet chartered as of available record) for any new fee or fee increase since 1980-11-04 (per Keller v. Marion County Ambulance District, 820 S.W.2d 301 (Mo. banc 1991) five-factor fee/tax test). Materially constrains impact-fee adoption — most MO cities do not levy transportation/parks impact fees under the Keller framework.
Effect
City may not levy a new tax/license/fee or increase existing such revenue source above 1980-11-04 level without voter approval. Practical effect on zoning: building-permit and plan-review fees OK if cost-of-service; transportation/parks impact fees structurally difficult under Keller test; no general MO impact-fee enabling statute. Capital infrastructure funding typically via TIF/CID/TDD or voter-approved sales-tax mechanisms (§94.577) rather than impact fees.
MO RSMo §89.145 (group homes for persons with disabilities)applies
Qualifying condition
RSMo §89.145 — Statewide. Applies to all MO municipalities including Fourth-class city under RSMo Chapter 79 (population ≈ 6,200; technically eligible for charter consideration under Art. VI §19 at >5,000 population but not yet chartered as of available record). Parallels federal Fair Housing Act but codified at state level. Citation-date 1989 is a conservative estimate — re-verify enacting session law against revisor.mo.gov.
Effect
Municipalities may not prohibit group homes of ≤8 unrelated persons with disabilities in any single-family zone.
MO HB 595 (2025) — source-of-income discrimination preemptionapplies
Qualifying condition
HB 595 (2025, 103rd G.A., 1st Reg. Sess.; Brown / Schroer), signed by Gov. Kehoe, effective 2025-08-28. Statewide — applies to all MO municipalities. Preempts municipal source-of-income discrimination ordinances and local restrictions on landlord background-check / security-deposit / right-of-first-refusal practices.
Effect
City cannot enact or enforce a source-of-income discrimination ordinance restricting landlord refusal based on tenant income source (including Section 8 vouchers). Tenant-screening / landlord-tenant practice rather than land use per se, but operates adjacent to fair-housing zoning policy.
MO RSMo Chapter 64 (county planning, zoning, recreation) — ETJ interactionapplies
Qualifying condition
RSMo Chapter 64 — Crawford County operates county zoning (or charter zoning if home-rule) under Chapter 64 class-specific subchapters. Applies only to UNINCORPORATED portions; does not directly preempt Fourth-class city under RSMo Chapter 79 (population ≈ 6,200; technically eligible for charter consideration under Art. VI §19 at >5,000 population but not yet chartered as of available record) zoning within municipal limits. Status per_parcel_conditional because effective constraint depends on whether the parcel sits inside or outside corporate limits.
Effect
County zoning controls land in unincorporated portions of the county and may affect the city's extraterritorial jurisdiction (ETJ) interactions and annexation patterns. Within municipal limits, Chapter 89 (not Chapter 64) governs.
Non-applicable laws (1)
MO statewide STR preemption (none in force)does_not_apply
Qualifying condition
No codified statewide STR-preemption statute. Bills SB 415/HB 615 (2024), SB 742/HB 482 (2025), refiled in 2026 session — none enacted as of 2026-05 review. SB 1066/HB 1768 (2026) passed both chambers, awaiting gubernatorial action — property-tax classification of STRs, not zoning preemption. Sentinel effective_date 1900-01-01 used to flag 'no enacting date'.
Effect
City retains full Chapter 89 / home-rule authority to regulate, cap, or prohibit short-term rentals subject only to federal constitutional and state uniform-ordinance constraints. Watch list: 2026 session HB 5529–5585 zoning-preemption block (posted to House Government Operations May 2026; outcome pending) and SB 1066/HB 1768 STR property-tax classification.

Quirks & notes

  • Small town context (pop. ~6,200) with simplified zoning structure
  • Historic downtown preservation focus with design review overlay authority
  • Two-tier residential gradient (R-1/R-2 single-family + R-3 multi-family) without state preemption requirements
  • Lot-coverage and FAR controls not explicitly documented; presumed controlled via setback requirements
  • No explicit transparency, ground-floor activation, or street-wall requirements for commercial districts
  • No accessory dwelling unit (ADU) provisions documented; not typical for small Missouri cities
  • Floodplain overlay triggers elevation and freeboard requirements affecting basement development
  • No zoning amendments or code rewrites documented as active or pending (as of April 8, 2026)
  • I-44 corridor position drives commercial highway-frontage development pressure; C-2 typically the relevant district.
  • Fourth-class status above the 5,000 charter-eligibility threshold (Art. VI §19) — city could move to charter but has not as of available record.
