Overview
Code type
rewrite-in-flight
Naming convention
use-type-index
Springfield adopted Land Development Code Chapter 36 in March 2025, consolidating 25+ density-indexed districts (R-7.5, R-10, R-15 etc.) into 14 use-type/placetype districts (R-SF, R-MHC, RMX-1, MU, C-1, C-2, COM, GI, I). This is a deliberate structural shift to match the Forward SGF 2040 Comprehensive Plan placetype framework — more comparable to Austin or Charlotte than to legacy Missouri zoning. RMX-1 (March 2026) is a 'missing-middle' contextual-design district requiring new multi-unit structures to be 'similar in size to single-family homes and designed to fit contextually within the neighborhood' — character-based rather than purely quantitative. All pre-2025 Planned Development / Conditional Overlay / Urban Conservation / Conditional Use Permits are retained under original guidelines (grandfather two-tier system). Citywide remapping project active since October 2025.
Worth knowing
- Code-rewrite-in-flight: 2025 consolidation from 25+ districts to 14; 2026 RMX-1 missing-middle adoption; ongoing remapping project from October 2025. Profile freshness_tier = volatile because dimensional standards and remapping outcomes are in active change.
- Two-tier overlay grandfathering: 25+ pre-existing PD/COD/UCD districts retained under their original approval ordinances despite the 14-district base consolidation.
- Use-type naming (R-SF, R-MHC, RMX-1) replaces traditional MO density-indexed coding (R-7.5, R-10) — unusual for Missouri; more comparable to Austin LDC or Charlotte UDO.

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). Charter city (constitutional charter under Mo. Const. Art. VI §19) — Springfield adopted its home-rule charter in 1953 (eligibility threshold of 5,000 population long exceeded). Population ≈ 169,000.. 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 Charter city (constitutional charter under Mo. Const. Art. VI §19) — Springfield adopted its home-rule charter in 1953 (eligibility threshold of 5,000 population long exceeded). Population ≈ 169,000.. 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 Charter city (constitutional charter under Mo. Const. Art. VI §19) — Springfield adopted its home-rule charter in 1953 (eligibility threshold of 5,000 population long exceeded). Population ≈ 169,000. 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 Charter city (constitutional charter under Mo. Const. Art. VI §19) — Springfield adopted its home-rule charter in 1953 (eligibility threshold of 5,000 population long exceeded). Population ≈ 169,000.. 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 — Greene 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 Charter city (constitutional charter under Mo. Const. Art. VI §19) — Springfield adopted its home-rule charter in 1953 (eligibility threshold of 5,000 population long exceeded). Population ≈ 169,000. 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.

All citations are to Springfield Chapter 36, City Council 2025 adoption notice, Forward SGF 2040 documentation, Commercial Street Historic District Design Guidelines, FEMA FIRM, federal Opportunity Zones TCJA-2017 designation, and standard MO preemption sources. (Springfield research markdown ends with a Zoneomics URL in the broader reference list; that is research-trail context, not a city-record citation.) |
| confidence tags full form | passed | v1 district standards were template-bleed fabricated 'partial' values (universal 5000/35/0.5/0.5 across all 11 districts). Per FM-6, these have been REMOVED in v2 rather than retained — district records preserve code/name/category (confirmed against City Council documentation per research markdown) but all dimensional KPIs are now null with explicit gap entry. This is the correct treatment of fabricated values: not 'downgrade to partial', but 'remove and document gap'. v2 overlay citations carry chapter-level reference (Chapter 36) with subsection numbers marked 'pending PDF retrieval'. |

Commercial Street Historic is fully confirmed (NRHP-listed 1983; 57 contributing buildings; documented Design Guidelines). Floodplain confirmed for Jordan Creek with technical specifics (minimum 2 flood openings). Other overlays are partial pending subsection retrieval. |
| preempt section city specific | passed | state_preemptions_applicable[] contains 8 Springfield-specific entries per preemptions.md, replacing v1's 'state-preemptions/missouri.md' pointer (which was a file reference, not a per-statute evaluation). MO-RSMo-89.020.2 noted as applies_permissive — Springfield is a charter city so has additional home-rule layer but the preemption applies equally. Greene County is non-charter; MO-RSMo-64 ETJ interaction noted. |
