Lodi — Nonconforming Uses

Last reviewed: July 3, 2026

Overview

Lodi’s rules for nonconforming uses, structures, and parcels are codified in Title 17 (Development Code), chiefly Chapter 17.68. The chapter recognizes lawful pre‑existing uses and physical conditions that no longer meet current zoning rules, permits their limited continuation, and sets the triggers that end nonconforming status. See § 17.68.010 and § 17.68.020 for the core rules.

How the Lodi code treats nonconformities (plain structure)

• The code’s purpose: discourage long-term continuation of nonconformities while allowing limited continuance where they lawfully existed before the current code. § 17.68.010.
• Major categories addressed: nonconforming uses, nonconforming structures, and nonconforming parcels (definitions in Article 7). § 17.68.010; definitions in Article 7.
• Common control rules: no expansion of a nonconforming use, 180‑day abandonment rule for loss of status, limits on reconstruction after destruction, and special exemptions for residential dwellings damaged by catastrophe. See § 17.68.020, § 17.68.040, § 17.68.060.

District-by-district breakdown (Lodi-specific)

The nonconforming rules in Chapter 17.68 apply citywide, but the underlying allowed uses and dimensional controls differ by zoning district. Below are the primary Lodi zoning districts and the development standards references you will need when assessing a nonconformity on a parcel. For the code rules that create or remove nonconforming status, see the cited sections in Chapter 17.68 (citywide rules that apply to all districts).

Note: to confirm parcel-specific allowable uses or dimensional numbers, check the district chapter referenced in each subsection (links point to the Development Code chapters summarized in the city code export).

• First, review Lodi’s zoning map and district list in the Development Code (Article 2). Lodi Zoning

Residential districts — RLD, RMD, RHD

Purpose and where used

• RLD, RMD, and RHD are Lodi’s residential districts for low-, medium-, and higher-density housing; their general development standards are in Chapter 17.18 and Table 2‑5.

Typical permitted uses

• Single‑family dwellings, two‑family, second dwelling units, small day‑care, home occupations (per Table 2‑9/2‑5). See Chapter 17.18.

Key dimensional/development standards (decision‑relevant)

• Minimum lot sizes, minimum lot area per unit, and setback rules for the residential districts are in § 17.18.040 and Table 2‑5. If a structure is nonconforming as to setbacks or lot coverage, additions must comply with the code or follow the limits in § 17.68.020.B.3.

Where the nonconforming rules matter most

• If a pre‑existing single‑family home sits in a newer non‑residential district, § 17.68.040 provides specific rebuilding flex for dwellings damaged by catastrophe (Government Code conformity noted).

Practical note

• ADU applicants should check both accessory rules and nonconforming limitations; ADU procedural issues intersect with nonconformities but ADU law may limit denial for purely zoning nonconformance (verify with the ADU rules). Lodi ADUs

Mixed‑use districts — DMU, MCE, MCO

Purpose and where used

• DMU, MCE, MCO are Lodi’s mixed‑use districts; see Chapter 17.22 and Table 2‑9 for FAR, height, and setback ranges. MCO is the Mixed Use Corridor and is specifically referenced in the nonconforming chapter for limited industrial expansion as of a date.

Typical permitted uses

• Ground‑floor retail, limited residential (upper floors), offices, food service—use tables specify A/UP/MUP status per use. See Table 2‑9 and Table 2‑6 for use lists.

Key dimensional/development standards

• Floor Area Ratio and height caps differ by mixed‑use subtype (e.g., FAR 3.0 in DMU vs FAR 1.2 in MCO; height floors/maximums in Table 2‑9). Alterations to structures that are nonconforming as to area/height/setbacks must meet the applicable development standards per § 17.68.020.B.3.

Where the nonconforming rules matter most

• The code explicitly allows certain existing industrial uses within the Mixed Use Corridor as of March 1, 2013, to expand on property they own (exception in § 17.68.020.A.6).

Industrial districts — M, BP

Purpose and where used

• M (Industrial) and BP (Business Park) districts address heavy and campus/light industrial uses; see Chapter 17.24 and Table 2‑10 for uses and FAR (e.g., M max FAR 0.6, BP max FAR 1.0).

Typical permitted uses

• Manufacturing, warehouse, distribution, selected service uses; permitted use lists and use permit requirements are in Table 2‑10.

Key dimensional/development standards

• Industrial standards (lot size, FAR) are in Chapter 17.24; physical nonconformities (height, setbacks) must be addressed per § 17.68.020.B.3–5 when altered or rebuilt.

Where the nonconforming rules matter most

• Expansion of legacy industrial uses inside the MCO corridor is a narrowly crafted allowance — see § 17.68.020.A.6.

Overlay districts — -F100, -F200

Purpose and where used

• Flood overlay districts -F100 and -F200 add flood hazard standards to the primary zoning district; see Chapter 17.28 and flood provisions in Article 2.

Typical permitted uses and standards

• Overlay provisions affect elevation, floodproofing, and which repairs are allowed after damage (see development standards for -F100/-F200). If a parcel is nonconforming because of overlay‑related dimensional constraints, Chapter 17.68 and the overlay chapter together apply.

Key intersection with nonconforming rules

• The overlays identify which repairs or replacements are allowed after damage and when reconstruction is permitted; nonconforming repair rules (e.g., 50% rule) in § 17.68.020.B.5 must be read together with overlay floodproofing requirements.

Quick reference table — core nonconforming rules

Practical interpretation & guidance (original plain‑English synthesis)

• The nonconforming rules are remedial and restrictive: if your business or building was lawful before the code change, you can usually keep operating as long as you do not enlarge the activity, move it, or let it stop for 180 days — otherwise the nonconformity disappears and the property must comply with current district standards (see § 17.68.020.A.3).
• Small repairs and maintenance are allowed for nonconforming structures; but if you plan to add floor area, raise height, shift setbacks, or substantially rebuild, expect to be required to bring the altered portions (and sometimes the whole structure) into compliance — and if a casualty exceeds 50% of assessed value you must rebuild to current code (§ 17.68.020.B.5).
• If a pre‑existing nonconforming parcel’s lot configuration is the issue, the code lists four ways it can be treated as a legal building site — gather title/subdivision documents early because the applicant bears the burden of proof (§ 17.68.060.A).
• Where design or site review is required (site plan/architectural approval), the director may require that review for development on a nonconforming parcel — expect site plan review in many nonconforming parcel projects (§ 17.68.060.B.1; see site plan rules at § 17.40.020).
• Overlays (like -F100/-F200) can add constraints (e.g., elevation/floodproofing) that interact with reconstruction rules — always read overlay chapters together with Chapter 17.68. Lodi Overlay Districts

Also remember to review related topics early in project planning: parking, development standards/setbacks, design review, and land use. These rules determine whether an alteration to a nonconformity can be processed administratively or requires a discretionary permit or variance.

Checklist — what an applicant dealing with a nonconformity must assemble

• Confirm whether the use/structure/parcel was lawfully established before the applicable code amendment (gather deeds, permits, historical site plans). (Applicant burden: § 17.68.060.A)
• Determine whether the activity has ceased for 180 days (if yes, nonconforming status may be lost). (Loss rule: § 17.68.020.A.3)
• For repairs/reconstruction: obtain cost estimates to determine whether the 50% reconstruction threshold applies. (Reconstruction: § 17.68.020.B.5)
• If proposing expansion, be prepared to show compliance with current use tables (Article 2) or to apply for a variance/use permit where required. (See § 17.12.030 and § 17.68.070)
• If parcel nonconformity is the issue, provide title/deed/subdivision documents, or a previously granted variance/lot line adjustment record. (Parcel proof: § 17.68.060.A)
• Check for overlay constraints (e.g., -F100) and attach required certifications (floodproofing, elevation) where applicable. (Overlay: Chapter 17.28; Flood standards in overlay subsections)

Risks & Ambiguities

Plain‑English summary

If your Lodi property or business was legal before a zoning change, Title 17 lets you keep operating in most cases — but you generally cannot enlarge the nonconforming activity, move it, or let it sit unused for 180 days, or you will lose the protection and must meet the current rules; rebuilding after major damage is limited by a 50% value test and special rules for dwellings. §§ 17.68.010–17.68.060.

Information Gaps

• The nonconforming chapter sets citywide rules but does not list a different nonconforming regime per zoning district — i.e., the code applies the same nonconforming limits across districts and refers applicants to district standards for what “conformance” is. The code does not provide district‑specific nonconforming exceptions beyond isolated items (e.g., Mixed Use Corridor industrial expansion). Not found in retrieved materials: any district‑by‑district special nonconforming rules beyond what is cited in Chapter 17.68.
• Precise administrative practice (how the department computes the 50% valuation, timelines for enforcement discovery, discretionary use of site plan approvals for nonconforming parcels) are not spelled out in Chapter 17.68 — these are practice items. Verify with the Community Development Department. Verify with the jurisdiction.
