Two-chapter structure. Chapter 16 is the citywide Zoning Code (R-1, R-2, RM, RH, C-M, CG, OC, BRP, HC, M-1, M-2, M-L, DTC). Chapter 17 is a separate Coastal Zoning ordinance covering parcels within the California Coastal Zone (Oxnard Shores, Channel Islands Harbor, Harbor area) under the city's certified Local Coastal Program (LCP). Both chapters coexist — which chapter applies depends on whether the parcel is inside the coastal zone boundary. This parallels LA Ch. 1/1A pattern and classifies as rewrite-in-flight per specialist 02 decision tree step 3.

Worth knowing
  • Two-chapter structure: Chapter 16 (citywide Zoning Code) + Chapter 17 (Coastal Zoning) coexist. Which chapter applies depends on whether the parcel is inside the California Coastal Zone. Classifies as rewrite-in-flight per specialist-02 decision tree. Parallels LA Ch. 1/1A pattern.
  • SOAR / CURB urban growth boundary: 1998 original voter ordinance (70% Yes) renewed by Measure L of November 8, 2016 (~75% Yes) extending the sunset to 2050. CURB coterminous with 1998 LAFCO Sphere of Influence. Voter approval required to annex land outside CURB.
  • Downtown Code (2019, rev. Feb 2023) is form-based with three sub-zones: Downtown Core (DT-C, up to 12 stories), Downtown General (DT-G, urban neighborhood), Downtown Edge (DT-E, transition to historic neighborhoods). Replaces the legacy single 'DTC' base-district treatment; carries forward use-differentiated FAR (office 3:1 vs retail/mixed-use 1.5:1).

Quirks & notes

  • Two-chapter structure: Chapter 16 (citywide Zoning Code) + Chapter 17 (Coastal Zoning) coexist. Which chapter applies depends on whether the parcel is inside the California Coastal Zone. Classifies as rewrite-in-flight per specialist-02 decision tree. Parallels LA Ch. 1/1A pattern.
  • SOAR / CURB urban growth boundary: 1998 original voter ordinance (70% Yes) renewed by Measure L of November 8, 2016 (~75% Yes) extending the sunset to 2050. CURB coterminous with 1998 LAFCO Sphere of Influence. Voter approval required to annex land outside CURB.
  • Downtown Code (2019, rev. Feb 2023) is form-based with three sub-zones: Downtown Core (DT-C, up to 12 stories), Downtown General (DT-G, urban neighborhood), Downtown Edge (DT-E, transition to historic neighborhoods). Replaces the legacy single 'DTC' base-district treatment; carries forward use-differentiated FAR (office 3:1 vs retail/mixed-use 1.5:1).
  • Height Overlay District: 6-story cap citywide where mapped, except Low Density Residential, Low-Medium Density Residential, Mobile Home Park, Airport Compatible, and Ventura County Harbor Public Works Plan areas (which follow their own standards).
  • §16-303 building height method: measured from average finished grade within 5 ft of the building; R-4 base cap is 4 stories / 45 ft; public/semi-public structures (schools, hospitals, churches) may go to 6 stories / 75 ft by special use permit.
  • AICUZ codification is split: height-surface component lives in OMC Ch. 16 Division 19 (Airport Hazard Overlay Zone); use-compatibility component is adopted by reference via AICUZ Study 2015 + NBVC JLUS.
  • Historic preservation is administered by the Ventura County Cultural Heritage Board under contract (also serves Port Hueneme, Fillmore, Simi Valley, Thousand Oaks). Henry T. Oxnard Historic District is Ventura County Landmark No. 161 and NRHP-listed (1999); ~70 acres, ~139 contributing buildings bounded roughly by F/G and Palm/5th Streets.
  • DETOD (Downtown East Transit-Oriented Development, 100 ac) entirely within ½ mi of Oxnard Transit Center — AB 2097 eliminates all parking mandates in this zone.
  • Chapter 17 Coastal Zoning uses distinct sub-zone codes: R-B-1 (Single-Family Beach), R-BF (Beachfront Residential), R-2-C (Coastal Multiple-Family, max 6 units/building), CPC (Coastal Planned Community). Coastal zone parcels are excluded from SB 9 ministerial pathway.
  • codelibrary.amlegal.com still returns 403 Forbidden to scripted WebFetch. Section-level numbers and text in this pass were confirmed via web-search snippets surfacing the amLegal content (multiple queries converged on the same §-level values).
