Overview
| residential_sf | Lot-size-encoded: SF-2 (2,000 sf min lot), SF-4 (4,000 sf), SF-6 (6,000 sf), SF-10 (10,000 sf), SF-20 (20,000 sf). Number = minimum lot area in thousands of sf. Direction is standard (not inverse). |
|---|---|
| residential_mf | Letter-code-by-intensity: RM-L (Low), RM-M (Medium), RM-H (High). RMX = mixed-residential combo district with 6 subtypes (SF detached, rowhouse interior/exterior, two-family, three-family, other). |
| downtown | DD-A, DD-B, DD-C, DD-D — downtown sub-zones with intensity gradient A→D (Ch. 1411). |
| mixed_use_transect | PX (Pedestrian Mixed-Use, build-to-line), NX (Neighborhood Mixed-Use), CX (Corridor Mixed-Use), MX (Regional Mixed-Use), IX (Industrial Mixed-Use) — LDC form-based transect zones (Chapter 1700-series). Applied in designated Neighborhood Business Districts (NBDs). |
| commercial | CG (General Commercial). |
| riverfront | RF-C (Riverfront Commercial), RF-M (Riverfront Mixed). |
| overlays | HS (Hillside / Ch. 1433), HCD (Historic Conservation / Ch. 1435), UD (Urban Design / Ch. 1437), IC (Industrial Conservation / Ch. 1431), IDC (Interim Development Control), PD (Planned Development / Ch. 1429). |
Cincinnati operates TWO parallel zoning code systems simultaneously: (1) Title XI Chapters 1400–1449 — traditional Euclidean districts governing most city land; AND (2) Land Development Code Chapter 1700-series — form-based transect zones (PX/NX/CX/MX/IX) introduced within designated NBDs and corridor study areas. The LDC is NOT a uniform rewrite — it layers as an alternate option in selected geographies. PD (Ch. 1429) is also a path for site-specific rezoning. Net: euclidean-base + form-overlay + PD-path = hybrid-pd-with-form-overlay. The 2024 Connected Communities ordinance (Emer. Ord. 199-2024) is an in-place use-table amendment to base SF-2/4/6/10/20 districts allowing 2/3/4-family + rowhouse in TOD/NBD proximity zones — not a code-type change. CRITICAL TITLE CORRECTION: v1 captioned this 'Title XIV' but authoritative Municode nodeId TIXIZOCOCI decodes as 'Title XI Zoning Code of Cincinnati' — Chapter range 1401–1449 is correct, the Roman numeral was a transcription error. | code_type_raw=hybrid-pd-with-form-overlay ; sub_flags_raw=[charter-city, form-overlay-coexists, topographic-hillside-dominant]

- Connected Communities reform (Emergency Ordinance 199-2024, effective June 2024) is the most significant local Cincinnati zoning reform in decades. Allows 2-, 3-, and 4-family housing AND rowhouses near NBDs in previously exclusively single-family zones (SF-2/4/6/10/20). Implemented as an in-place use-table amendment to §1403 base district — not a new district or overlay. Affects designated TOD/NBD-proximity mapped zones. — [c§Emergency Ordinance 199-2024 (June 2024); partial §1403 use-table amendments (specific § not re-fetched)]

Quirks & notes
- Cincinnati operates TWO parallel zoning code systems simultaneously: Title XI Chapters 1400–1449 (traditional Euclidean) governs most city land, while the Land Development Code (LDC) Chapter 1700-series introduces form-based transect zones (PX/NX/CX/MX/IX) within designated NBDs and corridors.

SF-2 at 2,000 sf is among the most permissive single-family minimum lot sizes of any major US city — typically reflects pre-WWII small-lot platting in OTR, West End, and inner-ring neighborhoods. — [c§1403-03 listing table (Wayback CDX confirms TIXIZOCOCI_CH1403SIMIDI_S1403-03SPPUSIMISU node-ID)]

Affects designated TOD/NBD-proximity mapped zones. — [c§Emergency Ordinance 199-2024 (June 2024); partial §1403 use-table amendments (specific § not re-fetched)]
- LIHTC projects receive automatic zoning relief embedded in the LDC (§1703-5.50 per v1): lot area density relief, parking minimums waived, and 12 ft height bonus. This is a city-level affordable housing incentive mechanism built directly into the zoning code — Cincinnati is unusual in having codified LIHTC-specific dimensional bonuses. — [partial §1703-5.50 (v1-carried; specific § not re-fetched)]
- Setback escalation for RM buildings above 35 ft is governed by TWO alternative formulas in Schedule 1405-07 — (a) 1 ft setback per 1 ft height OR (b) 1 ft per 5 ft height — with side-yard escalation adding 0.5–1 ft minimum and 1–2 ft total per formulation. Specific application is unclear from available sources and requires direct §1405-07 read against the as-built case. — [partial §1405-07 (Wayback CDX confirms TIXIZOCOCI_CH1405REMUMIDI node-IDs; formula text not re-extracted)]
- Hillside Overlay (HS / Ch. 1433) affects a substantial share of Cincinnati's residential land given the city's dramatic topography — not a rare exception but a common condition throughout much of the city. Combines slope-stability, erosion, grading, and drainage controls with Zoning Hearing Examiner review (Three-Month IDC sub-type also available). — [c§Ch. 1433 (Wayback CDX confirms _CH1433HIOVDI, _S1433-15APRE, _S1433-19BADERE, _S1433-21AP, _S1433-23HIDEST)]
- Cincinnati is a CHARTER city (1924 Council-Manager charter); ORC Chapter 713 procedural enabling and §713.15 nonconforming-use floor do NOT automatically apply. Cincinnati's charter and Title XI Ch. 1443 Zoning Hearing Examiner / Ch. 1447 Nonconforming Use Standards / Ch. 1449 Zoning Appeals govern. v1's link to 'state-preemptions/no-preemption.md' was structurally wrong for Ohio — home-rule meta-framing plus 2 active municipal-applicable preemptions (§5104.054 Type B child care + §3781.184 federal MH construction) always apply. — [c§Ohio Const. Art. XVIII §7; zoning/us/ohio/preemptions.md#charter-status (Cincinnati listed among charter cities)]
- ORC §5104.054 Type B family child care homes must be permitted as-of-right in all residential districts (SF-20/10/6/4/2, RMX, RM-L/M/H, plus residential portions of mixed-use districts) as of 2025-01-01 — Title XI provisions requiring special exception for these are legally unenforceable post-HB 33. — [c§ORC 5104.054; c§HB 33 (135th GA)]
- Ohio River, Mill Creek, and Little Miami River corridors create substantial FEMA NFIP SFHA constraint through major portions of the city — south side along Ohio River, Camp Washington/Northside/Queensgate along Mill Creek, east Cincinnati along Little Miami. v1 OMITTED FEMA NFIP overlay entirely; v2 adds as federal floor with local-chapter location TBD. RF-C and RF-M base districts directly intersect SFHA. — [c§44 CFR 60.3 (NFIP minimum); c§FEMA Community Status Book Cincinnati 390137; partial §Title XI / Codified Ordinance local flood damage prevention chapter]
- Title XI Municode platform is SPA-gated: direct HTTP GET to library.municode.com/oh/cincinnati returns the AngularJS shell (~6 KB) regardless of User-Agent. Wayback Machine captures are also SPA shells because Wayback's crawler does not execute JavaScript. The 60+ Wayback CDX entries are useful for confirming canonical chapter/section node-IDs but NOT for extracting dimensional table content. This blocks deep re-fetch of Schedule 1403-07 (SF dimensional table), Schedule 1405-07 (RM dimensional table), and Ch. 1700-series LDC text.

Formulas
Definitions
- height
- Maximum vertical distance from finished grade to roofline or architectural feature; measured per Title XI definitions in Ch. 1401. partial §1401 (Municode SPA 403 this pass)
- lot_coverage
- Building footprint area divided by total lot area; decimal format (0.50 = 50%). Explicit lot_coverage caps are NOT surfaced for most Title XI base districts in v1 extraction — coverage is implied via setback + envelope geometry. IX district explicitly carries facade-zone coverage = 50% per LDC §1703.
- du_per_acre
- Dwelling units per acre; for SF tier derived from min_lot_sf-per-unit (43560 / min_lot_sf). Title XI does not appear to cap du/ac directly as a per-district numeric in SF tier; RMX uses min_lot_sf_per_unit instead.
- setback_escalation_rm_above_35ft
- For RM (RM-L/M/H and RMX) buildings above 35 ft: Schedule 1405-07 specifies two alternative formulas (either 1 ft setback per 1 ft height OR 1 ft per 5 ft height); side yard escalation adds 0.5–1 ft minimum and 1–2 ft total per formulation. Specific application unclear from available sources — requires direct §1405-07 read. partial §1405-07 (Municode SPA 403)
- form_based_build_to_line
- Form-based transect districts (PX, NX, CX, MX, IX) use build-to-line not setback. PX is build-to-lot-line (0 ft front). MX specifies 5–12 ft front range. IX specifies 5–85 ft front range. partial §1703
- ldc_lihtc_relief
- LIHTC projects receive automatic zoning relief per §1703-5.50: lot area density relief, parking minimums waived, 12 ft height bonus. City-level affordable housing incentive embedded in zoning code. partial §1703-5.50
