Stockton — Overlay Districts

Last reviewed: July 2, 2026

Overview

Overlay districts in Stockton are special zoning suffixes that add area-specific rules on top of the city's base zoning. The overlay rules govern land use, development standards, and discretionary review in areas with unique concerns (airport safety, waterfront access, historic character, design control, and industrial/commerce compatibility). These overlays are codified in the Development Code under Chapter 16.28 and applied in combination with the primary zoning shown on the Zoning Map (for example, CG-CHA). See the city's base Stockton Zoning and Stockton Development Standards for how overlays interact with underlying district rules. The ordinance language establishing purpose and applicability is in § 16.28.010 and § 16.28.020 .

How to read this page

• Whenever I quote a controlling requirement I cite the exact code section (for example, § 16.28.030) and the uploaded code file citation so you can verify the text. Where the code references other chapters (for example design review or use permits), I cite those cross-references as given in the Development Code; verify parcel-level application with the City. If something is not in the retrieved materials I mark it "Not found in retrieved materials."

Overlay districts (district-by-district)

-DES (Design Review) — § 16.28.050

• Purpose: The -DES overlay promotes high-quality, compatible exterior design and requires projects to be reviewed to avoid poor design and protect neighborhood character. See § 16.28.050 .
• Applicability: The -DES overlay “may be combined with any zoning district” established by § 16.16.020 and controls where applied on the Zoning Map (suffix form, e.g., R-1-DES) .
• Typical permit/process: Projects within -DES cannot add, construct, or enlarge structures without design review in compliance with Chapter 16.120 (Design Review) and the Citywide Design Guidelines; the code makes the overlay control in any conflict with other code provisions (see § 16.28.050(C)) .
• Key practical notes: Expect mandatory design-review submittals, and that design conditions or design-based denials are authorized under this overlay. For what design review entails in Stockton, consult the city Stockton Design Review.

-MHD (Magnolia Historic District) — § 16.28.060 and Table 2‑4

• Purpose: The -MHD overlay recognizes and protects architecturally or culturally significant resources in the Magnolia area and preserves neighborhood historic character (§ 16.28.060(A)) .
• Applicability: The -MHD overlay is combined with an underlying residential or other zoning district within the Magnolia historic boundaries (§ 16.28.060(B)) .
• Allowed uses and permits: Table 2‑4 in the code lists the allowed land uses and permit requirements for the Magnolia district (single‑family, multifamily, certain commercial uses, bed & breakfasts, child care, etc.) and ties specific use standards to other code sections (for example, 16.80.220, 16.80.090, 16.80.100) .
• Key practical notes: Projects in -MHD are limited to the uses in Table 2‑4; alterations to historic resources will be evaluated under the Magnolia standards and the City’s historic rules — see Stockton Historic Preservation.

-AIR (Aircraft Operations / Airport Overlay) — § 16.28.030

• Purpose: The -AIR overlay sets height limits and prohibits activities that interfere with aircraft operations in areas around Stockton Metropolitan Airport (§ 16.28.030(A)–(C)) .
• Applicability: The overlay may be combined with any residential, commercial, industrial, or special-purpose zoning district; map application follows airport zones and the Stockton Metropolitan Airport Land Use Plan (§ 16.28.030(C)) .
• Key restrictions and standards:
  • Uses that create electrical interference, glare, impair visibility, or otherwise endanger aircraft are prohibited (§ 16.28.030(D)) .
  • No residential or public assembly uses are allowed within an inner 10,000‑foot section of any precision instrument approach surface (with limited exceptions such as air shows) (§ 16.28.030(D)(3)) .
  • Height and airport zone definitions and limits are established in the airport‑zone subsections; the code directs consistency with FAA Part 77 surfaces and the Airport Land Use Plan (§ 16.28.030(G)) .
• Practical note: For a parcel in an -AIR overlay, expect referral to the Airport Manager/ALUC and FAA coordination for height variances; variances require special findings (see § 16.172.050 referenced in the variance rules) .

-CHA (Channel Area / Waterfront) — § 16.28.040

• Purpose: The -CHA overlay promotes public waterfront access, protects riparian resources, and encourages walkable mixed uses consistent with the Waterfront Connections Plan and the General Plan (§ 16.28.040(A)) .
• Applicability: The -CHA overlay is combined with the underlying zoning district where mapped (§ 16.28.040(B)) .
• Permitting and special areas:
  • Generally, new construction, enlargements, or intensified uses require a Commission use permit under Chapter 16.168 (§ 16.28.040(C)) .
  • There is a defined Marine Commercial Subarea (MCS) where certain marine‑oriented uses can expand without a use permit; other marine uses require a CUP (§ 16.28.040(D)) .
• Practical note: Projects on waterfront parcels will be reviewed for public access, resource protection, and walkability; landscaping/screening and signage rules may be applied — see Stockton Landscaping and Screening and Stockton Signage.

-CI (Commercial‑Industrial) — § 16.28.070

• Purpose: The -CI overlay preserves urban industrial land for employment uses while buffering heavy industrial activity from residential neighborhoods; allowable uses include light industrial, clean manufacturing, food processing, offices that support production, and compatible commercial uses (§ 16.28.070(A)) .
• Applicability: The -CI overlay may be combined with an underlying commercial zoning district; conflicting provisions in the overlay control (§ 16.28.070(B)) .
• Allowed uses & development standards:
  • The code lists allowable land uses and permit requirements (artisan food & beverage, light manufacturing, warehousing, etc.) in a table within § 16.28.070(C); many uses are allowed subject to specific standards in 16.80.170 and similar cross‑references (§ 16.28.070(C)) .
  • Development standards (§ 16.28.070(D)) require enclosed operations (with limited exceptions such as loading docks and parking), screening for open storage and equipment, minimum landscaping and compliance with other chapters for walls/fences and light/glare rules, and maximum fixture heights adjacent to residential uses (lighting guidance) .
• Practical note: Expect strict screening and operational conditions for outdoor storage, lighting controls near riparian areas, and compliance with general performance standards (air, noise, odor) documented in Chapter 16.32 .

Checklist — what an applicant must satisfy (overlay workstream)

• Identify whether your parcel carries an overlay suffix on the Zoning Map (e.g., -DES, -CHA, -AIR) — Chapter 16.28 rules apply (§ 16.28.020) . Verify with the City.
• Confirm applicable permit type (design review, Commission CUP, administrative permit) listed in the overlay section (e.g., § 16.28.050(C) for -DES; § 16.28.040(C) for -CHA) .
• For -DES: Prepare design‑review submittals per Chapter 16.120 and the Citywide Design Guidelines; link design choices to the overlay purpose (§ 16.28.050) . See Stockton Design Review.
• For -AIR: Provide height studies, FAA/ALUC coordination, and ensure uses don’t create interference/glare; address airport‑zone mapping (§ 16.28.030) .
• For -CHA waterfront projects: Provide public access plan, resource protection measures, and expect Commission CUP unless your parcel is in the MCS where limited marine expansions may be allowed (§ 16.28.040(D)) .
• For -CI: Provide screening plans, enclosed‑use justification for industrial activities, lighting plans that comply with glare rules and landscaping per Chapter 16.52 (§ 16.28.070(D)) . See Stockton Landscaping and Screening.
• Confirm cross‑references (e.g., use tables in Chapter 16.20, development standards in Chapter 16.24, parking in Chapter 16.64); attach required engineering and site plans. See Stockton Parking and Stockton Development Standards.
• If adding an ADU, check ADU provisions and whether the overlay imposes additional discretionary review (the code points to ADU rules — see 16.80.310) and the City ADU guide Stockton ADUs. Verify conflicts with state ADU law California ADU law.

Risks & Ambiguities

Plain‑English Summary

Stockton’s overlay districts (the -DES, -MHD (Magnolia), -AIR, -CHA, and -CI overlays) are map‑based suffixes added to base zoning that impose additional use limits, design review, height rules, or waterfront/industrial protections; the specific rules and permit triggers are in Chapter 16.28 of the Development Code and must be checked for each parcel before submitting plans (see § 16.28.010–§ 16.28.070) .
