Athens is a non-charter statutory municipal corporation (zoning authority derived from ORC Chapter 713). ACC 23.05.02 (nonconforming uses) explicitly distinguishes 'R-Zone' and 'B-Zone' as the primary residential/business categories — the v1 profile's use of 'C-1/C-2/C-3' for commercial districts is inconsistent with this primary-source evidence and has been flagged as requires-verification. Full district inventory beyond R-1/R-2/R-3/B/M-1/M-2 is not confirmed and should be re-extracted once direct Municode access is restored or a PDF export is obtained. | naming_convention_raw=hierarchical-letter-numeric ; sub_flags_raw=[university-town, appalachian-small-city]

Worth knowing
  • v1 profile cited 'Chapters 1155–1157' for Athens zoning — this is the Ohio municipal code numbering style used by some other Ohio cities (e.g., Hamilton, Middletown) but is INCORRECT for Athens, which organizes its zoning code as ACC Title 23 (multi-chapter). Primary-source BZA filings (March 2023) confirm citations like §23.04.01, §23.05.02, §23.07.09(C), §23.10.01 Table B, and §25.05.04. All v1 ordinance_ref strings referencing §1155-x are superseded by this v2 regeneration. — [c§Athens BZA-5 packet March 30, 2023 (Case #23-02V, 23 First Street) — primary-source document referenced ACC Title 23 section numbering]
  • Athens uses 'R-Zone' and 'B-Zone' as the primary residential and business category labels in ACC §23.05.02 (nonconforming-use substitution rules); v1 profile used 'C-1/C-2/C-3' for commercial districts which is inconsistent with primary-source evidence. The correct commercial/business naming is expected to be B-1/B-2/B-3 (sub-district numbering not re-confirmed this pass). — [c§ACC §23.05.02 (Athens BZA-5 packet March 2023)]
  • Athens is a non-charter statutory municipal corporation under ORC Chapter 713. The Board of Zoning Appeals operates under §713.11 enabling with a 5-member quorum requirement (confirmed in 2023 BZA-3 Notice of Hearing which states 'If fewer than five (5) members are available for the meeting, you have the right to continue until such time as five (5) members are available'). Public-hearing notice ≥30 days per §713.12. — [c§ORC §§713.11, 713.12; c§Athens BZA-3 Notice (March 30, 2023)]

State preemptions

OH-CONST-ART-XVIIIapplies
Qualifying condition
Athens is a non-charter municipal corporation in Ohio (verified: no charter on file per Ohio Municipal League charter roster; operates under statutory enabling authority). Ohio Constitution Article XVIII §§3, 7 grants 'all powers of local self-government' to municipalities; statewide preemption of municipal zoning requires a 'general law' under the Canton v. State (2002) four-part test.
Effect
Athens retains broad home-rule authority over local zoning. State preemption is narrow: Type B family child care homes (§5104.054), federal manufactured-home construction standards (§3781.184), nonconforming-use substantive floor (§713.15). No statewide density, height, parking, by-right multifamily, or STR preemption is in effect as of April 2026.
OH-713-CH-ENABLINGapplies
Qualifying condition
Athens is a non-charter statutory municipal corporation; no charter on file. ORC Chapter 713 (§§713.06–713.15) governs the zoning enabling procedure for non-charter municipalities — planning commission authority (§713.06), use regulation (§713.07), height regulation (§713.08), bulk/setbacks/lot coverage (§713.09), districting (§713.10), BZA/appeals/variances (§713.11), public hearing notice ≥30 days (§713.12), nonconforming uses (§713.15).
Effect
Procedural preemption: ACC Title 23 adoption and amendment must comply with Chapter 713 procedure. Athens' BZA operates under §713.11 enabling (confirmed by BZA Form BZA-3/BZA-5 procedure and 5-member quorum rule in the March 2023 BZA-5 notice). §713.15 provides a substantive floor: 2-year discontinuance rule for nonconforming-use grandfather status, which ACC §23.05 implements with explicit substitution rules (R-to-R, B-to-B only) more restrictive than the statutory floor.
OH-5104.054applies
Qualifying condition
Athens is a municipal corporation; ORC §5104.054 (amended effective 2025-01-01 by HB 33) applies uniformly to 'cities, villages, townships, and counties.' Type B family child care homes (1–6 children in caregiver's personal residence) must be treated as a permitted residential use in all districts where any residential use is permitted, and no conditional use permit or special exception may be required.
Effect
Any ACC Title 23 provision requiring a conditional use permit, special exception, or additional standards for a Type B family child care home in an R-Zone is unenforceable as of 2025-01-01. Type A homes (7–12 children) are NOT covered and remain subject to local zoning.
OH-3781.184applies
Qualifying condition
All Ohio jurisdictions. 42 U.S.C. §5415 / National Manufactured Housing Construction and Safety Standards Act federal construction standards are exclusive in Ohio per ORC §3781.184. Municipal corporations are NOT bound by the §519.212/§303.212 township/county zoning preemption for permanently sited manufactured homes — cities retain full zoning discretion on placement within corporate limits.
Effect
Athens may not impose construction standards (roof pitch, wall thickness, etc.) conflicting with federal HUD standards on manufactured homes. Athens retains full zoning authority over WHERE permanently sited manufactured homes may be located — §519.212 does NOT extend to municipal corporations.
Non-applicable laws (1)
OH-SB-104-STRunder_review
Qualifying condition
Ohio SB 104 (136th GA) STR preemption is PENDING in Senate Local Government Committee (last updated May 28, 2025) and NOT enacted as of April 2026. HB 109 (companion) is pending in House Development Committee. Until enacted AND surviving any home rule challenge, STR regulation remains fully local in Ohio. | reason=Bill pending in committee; not yet law. Per zoning/us/ohio/preemptions.md Activity Level verdict (Low), Ohio has no MBTA/SB-9/SB-840-style statewide preemption in effect.
Effect
None currently. If SB 104 or HB 109 enacts: Athens would lose authority to ban STRs via zoning, impose lottery licensing, cap per-operator rentals, or require owner-occupancy; registration fee would cap at $20/unit. Flag for re-check if bills advance beyond committee.

Quirks & notes

  • v1 profile cited 'Chapters 1155–1157' for Athens zoning — this is the Ohio municipal code numbering style used by some other Ohio cities (e.g., Hamilton, Middletown) but is INCORRECT for Athens, which organizes its zoning code as ACC Title 23 (multi-chapter). Primary-source BZA filings (March 2023) confirm citations like §23.04.01, §23.05.02, §23.07.09(C), §23.10.01 Table B, and §25.05.04. All v1 ordinance_ref strings referencing §1155-x are superseded by this v2 regeneration. — [c§Athens BZA-5 packet March 30, 2023 (Case #23-02V, 23 First Street) — primary-source document referenced ACC Title 23 section numbering]
  • Athens uses 'R-Zone' and 'B-Zone' as the primary residential and business category labels in ACC §23.05.02 (nonconforming-use substitution rules); v1 profile used 'C-1/C-2/C-3' for commercial districts which is inconsistent with primary-source evidence. The correct commercial/business naming is expected to be B-1/B-2/B-3 (sub-district numbering not re-confirmed this pass). — [c§ACC §23.05.02 (Athens BZA-5 packet March 2023)]
  • Athens is a non-charter statutory municipal corporation under ORC Chapter 713. The Board of Zoning Appeals operates under §713.11 enabling with a 5-member quorum requirement (confirmed in 2023 BZA-3 Notice of Hearing which states 'If fewer than five (5) members are available for the meeting, you have the right to continue until such time as five (5) members are available'). Public-hearing notice ≥30 days per §713.12. — [c§ORC §§713.11, 713.12; c§Athens BZA-3 Notice (March 30, 2023)]
  • Athens is home to Ohio University (Main Campus, ~28,000 students). Ohio University is a state agency under ORC Chapter 3337; state-owned campus property is largely exempt from local zoning under Ohio sovereign-property doctrine. The 'University District Overlay (UD)' that v1 included as a formal overlay is NOT confirmed to exist in ACC Title 23 — it was likely an inferred feature rather than a codified overlay. Reclassified from overlay to quirk until a direct Title 23 fetch confirms otherwise. Off-campus student-housing rental-permit regulation IS active via Title 23 + ACC §23.04.01(A)(1) 'one family per dwelling' occupancy limits. — [v1 misclassification; state-agency exemption per ORC Chapter 3337 and Hamilton Twp. v. State doctrine]
  • Rental-housing permits required per ACC Title 23; ACC §23.04.01(A)(1) defines 'One Family per' unit as the max-occupancy for residential rental. ACC §23.10.01 Table B establishes off-street parking requirements — primary-source 2023 variance case (Case #23-02V, 23 First Street, Zone R-1) required 3 off-street parking spaces for a 3-person unrelated-occupancy rental unit; applicant had zero and sought variance. This indicates a parking ratio of approximately 1 space per occupant for rental occupancy, which is stricter than many Ohio peer cities. — [c§ACC §23.04.01(A)(1), §23.10.01 Table B; c§Athens BZA Case #23-02V packet]
  • ACC §23.05 nonconforming-use rules are STRICTER than the ORC §713.15 state-law floor: Athens restricts substitution of nonconforming uses such that 'in an R-Zone, no change shall be authorized to any use that is not a permitted or conditionally permitted use in any R-Zone; in a B-Zone, no change shall be authorized to any use that is not a permitted or conditionally permitted use in any B-Zone.' ORC §713.15 only requires a 2-year discontinuance floor (can be shortened to 6 months by ordinance); Athens' rule goes further by preventing same-category substitution only. — [c§ACC §23.05.02(A); c§ORC §713.15]
  • The Hocking River runs through downtown Athens and the university campus; the floodplain overlay at ACC §25.05 is operationally significant (not a marginal overlay). BZA variance applications for flood-hazard work follow a separate procedure from bulk-control variances under §25.05.04 (11 enumerated evaluation factors). — [c§ACC §25.05.04 (Athens BZA-5 packet March 2023)]
  • ORC §5104.054 (HB 33, effective 2025-01-01) preempts any ACC Title 23 requirement for conditional use permits or special exceptions for Type B family child care homes (1–6 children) in R-Zones — these must be permitted as-of-right. Athens should audit Title 23 for any remaining conditional-use language for Type B homes; such provisions are unenforceable as of 2025-01-01. — [c§ORC §5104.054; zoning/us/ohio/preemptions.md]

FP overlay carries c§ citation to ACC §25.05.04 (confirmed via primary-source BZA PDF). HD overlay is status=partial with explicit partial_reason. UD is status=not_found with search_performed rather than being silently dropped — preserves v1's inference while flagging it as unconfirmed.

Each row carries qualifying_condition_checked specific to Athens (non-charter status, municipal corporation vs. township/county distinction, bill-pending-not-law reasoning). v1 profile pointed state_preemptions to 'state-preemptions/no-preemption.md' which was WRONG — Ohio has four operative preemptions applicable to municipal corporations (home rule framework, Chapter 713, Type B child care, federal construction) plus SB 104 watch; v2 captures all five as city-specific rows.
