Dinuba — Nonconforming Uses

Last reviewed: July 3, 2026

Overview

This page summarizes how the City of Dinuba treats nonconforming uses, nonconforming structures, and nonconforming lots under the local zoning code (Title 17). It synthesizes the operative standards (limits on continuation, repair/restoration, expansion, abandonment, and elimination) and where those rules differ by district. Where possible each rule is grounded in the Dinuba ordinance text (chapter and §) so you can verify the raw language. See the city’s rules on development standards and parking where related standards are applied.

IMPORTANT: This page interprets the ordinance; it does not replace it. For parcel‑specific questions, Verify with the jurisdiction.

What the ordinance says (core rules)

• Purpose: A use or structure lawfully established before the current code that does not meet the new zone rules is a nonconforming use or nonconforming structure and may be continued only to the extent and under the limitations set out in Chapter 17.96. § 17.96.010 .

• Continuation and maintenance: A lawfully existing nonconforming use/structure on the ordinance effective date may continue under limits in Chapter 17.96; routine maintenance and repairs are expressly allowed. § 17.96.020; maintenance permission noted in § 17.96.020(D).

• Nonconforming structures vs. nonconforming uses:

  • A structure nonconforming only because of height, yard, or area requirements is treated as a conforming structure for some rules and may be structurally altered or enlarged to comply with setback/height rules (subject to other requirements). § 17.96.030(B); § 17.96.070(B).
  • A nonconforming use that occupies a nonconforming structure may be extended throughout that structure; a nonconforming use in a conforming structure may not be extended into additional portions of the building. § 17.96.030(A); § 17.96.040(A).

• Repairs / restoration after damage: If a nonconforming structure is damaged or destroyed up to 75% of its value, it may be restored and the former occupancy continued; if destroyed more than 75%, it may not be restored except in conformity with the Title. § 17.96.060(A–B).

• Expansion and remodeling limits: Modest expansion or remodeling of a nonconforming residential structure is limited to 50% or less of the value of the existing structure; other structural alterations are restricted unless required to make the building conform or unless the nonconformance is only by yard/height. § 17.96.070(C); § 17.96.070(A–B).

• Elimination / time limits:

  • A nonconforming use of land that does not occupy a structure may be continued for no more than three (3) years after the effective date. § 17.96.050(A).
  • A nonconforming use that is discontinued, abandoned, or changed to a conforming use for 90 continuous days may not be reestablished. § 17.96.090.
  • If a nonconforming building or structure is removed, future use must conform to the Title. § 17.96.080(B).

• Specific special rules:

  • In R zones, every nonconforming structure other than a residential dwelling designed for a use not permitted in the zone must be removed or altered to conform — but the Director will set a reasonable removal/alteration schedule that in no event is less than 40 years from original construction unless otherwise provided; also no order shall require removal sooner than 3 years after the order. § 17.96.080(D)(1–4).
  • Nonconforming home occupations must be discontinued within one (1) year. § 17.96.080(E).
  • Fences, walls and hedges that are nonconforming at intersections must be removed or made conforming within one month after written notice. § 17.96.080(F).
  • The Planning Department must notify owners of nonconforming properties within one (1) year after ordinance effective date and attach an excerpt of the title. § 17.96.110.
  • Public structures (utilities, public facilities) are excepted from nonconforming termination requirements so long as there is no change of use or increase in area. § 17.96.120.

• Enforcement: Violations of Title 17 (including illegal nonconforming uses) are public nuisances; the City has administrative and enforcement remedies under Chapter 17.98. § 17.98.040–060.

District-by-district breakdown (how nonconforming rules interact with major Dinuba districts)

Important: the ordinance uses several district labels. Where district-specific permitted uses or standards are cited below, the source ordinance fragment is provided. For full permitted-use lists see the cited use tables in the ordinance.

R (single-family residential) and R-1-6

• Purpose / Where it applies: Residential zones intended for one‑family dwellings and accessory uses; sample setbacks for R-1-6 appear in the development-modification table. See Dinuba Zoning for maps. § 17.92 (setback table) and residential use table § 17.26.
• Typical permitted uses: single‑family dwellings, accessory buildings, limited home occupations (subject to Chapter 17.70). § 17.26.
• Key dimensional standards: Example R-1-6 front setback = 10 ft; side = 5 ft; rear = 15 ft (see the development standards table). § 17.92 (Setbacks table).
• How nonconforming rules apply:
  • Nonconforming residential dwellings may continue; nonconforming structures intended for nonresidential use in R zones must be removed or altered within the timing rules the Director sets (not less than 40 years from original construction and not sooner than 3 years after an order). § 17.96.080(D).
  • Modest residential expansions allowed up to 50% of structure value per § 17.96.070(C).

RM (multifamily residential; includes RM-1.5, RM-2, RM-3)

• Purpose / Where it applies: Medium‑ and higher‑density residential districts for duplexes, townhomes and multifamily. See the density and setback columns in § 17.92 and permitted-use grids in § 17.26.
• Typical permitted uses: multifamily dwellings, accessory units, limited community services. § 17.26.
• Key dimensional standards: Example RM-2 front setback = 15 ft; side = 5 ft; rear = 15 ft in the modified standards table. § 17.92.
• How nonconforming rules apply: Same Chapter 17.96 limits; structural repairs and limited expansions subject to the 50% rule for residential remodeling. § 17.96.070(C).

PO (professional office / public)

• Purpose / Where it applies: Offices and professional services adjacent to residential or commercial areas; PO-specific accessory standards appear in Chapter 17.71. § 17.71(G).
• Typical permitted uses: Offices, professional services, limited institutional uses; see district use tables. § 17.26 / 17.54.
• How nonconforming rules apply: Nonconforming structures and uses in PO are continued under Chapter 17.96; wall and fencing waivers in PO appear in § 17.92(G) and relate to nonconforming fence rules. § 17.96.020; § 17.92(G).

C (Commercial) and P (Public)

• Purpose / Where it applies: Retail, services, public uses. Permitted uses and conditional uses are detailed in the commercial use tables (see Chapters for commercial uses). § 17.54.
• Typical permitted uses: Retail stores, professional offices, restaurants (use table variances apply). § 17.54.
• How nonconforming rules apply:
  • A nonconforming structure in a C or M zone may be continued (the code explicitly allows continuation in those zones). § 17.96.080(C).
  • Expansion/remodeling rules apply; parking requirements for existing uses are protected by § 17.64.090 (existing uses are not nonconforming solely for lacking off‑street parking). See parking. § 17.64.090.

M, M1, M2 (Industrial / Manufacturing)

• Purpose / Where it applies: Light and heavy industrial/manufacturing uses; detailed in Chapter 17.54 use tables. § 17.54.
• Typical permitted uses: Manufacturing, repair, storage yards, some heavy uses listed with conditional (U/A) status in use tables. § 17.54.
• How nonconforming rules apply:
  • Nonconforming structures in M zones may be continued. § 17.96.080(C).
  • For any expansion or reduction of parking/loading, Chapter 17.64 and the conditional use / variance chapters control applicability. § 17.64.100; see Variances and Exceptions.

Decision‑relevant standards and permitted‑use quick table

Practical guidance / synthesis (how this plays out for property owners)

• Establish lawful prior use: To claim nonconforming status, you must show the use or structure was lawful before the zoning change. The ordinance assumes existing lawful uses/structures are nonconforming but the burden of proof and exact treatment depends on the specific § cited. § 17.96.020.

• Repair vs. replace: If damage is ≤ 75%, the code allows restoration to the previous occupancy; if damage is > 75%, you must rebuild to current standards (or reapply for a different lawful use). § 17.96.060.

• Limited expansion allowed for residences: A homeowner may remodel or expand a nonconforming residential structure up to 50% of the structure’s value without triggering full compliance (subject to other Chapters and design review where applicable). § 17.96.070(C).

• Changes to district rules or zone lines: When a property becomes nonconforming due to rezoning, time limits run from the effective date of that change; the Building Official carries out the notification rules. § 17.96.100–110.

• Parking interactions: Existing uses without the modern off‑street parking standard are not automatically nonconforming solely for parking; however, expansions may trigger the current parking requirements—see parking. § 17.64.090–100.

• If you want different relief (longer expansion, variance in setbacks, or to change the use), consult the ordinance’s discretionary permit/variance procedures (Chapter 17.80) and the development standard modification rules § 17.93; the Director or Planning Commission processes many of these requests. § 17.96.070(C); § 17.93.030–040.

Checklist (what an applicant/property owner must be ready to show / do)

• Demonstrate the lawful establishment date and nature of the prior use/structure (date-stamped deeds, permits, tax records). § 17.96.020
• For repair/restoration after damage, document loss valuation to show whether damage was ≤ 75% or > 75%. § 17.96.060
• If proposing expansion of a nonconforming residential structure, prepare valuation evidence to stay within 50% rule or seek discretionary approval. § 17.96.070(C)
• If use has been discontinued, confirm the 90‑day abandonment rule has not extinguished nonconforming rights. § 17.96.090
• Check whether the property falls in a special district / overlay that changes standards; consult the overlay districts rules and the official zoning map. Verify with the city. Not found in retrieved materials (map specifics).
• Review off-street parking status and whether any changes trigger parking requirements. § 17.64.090

Risks & Ambiguities

Plain‑English Summary

If your building or use in Dinuba was legal before the current zoning rules changed, you usually can keep it — but repairs, expansions, and rebuilding are limited: small residential remodels (≤ 50% of value) and repairs after damage (if ≤ 75% destroyed) are allowed, abandonment for 90 days cancels the nonconforming right, and some nonresidential structures in R zones must be removed or converted on a schedule the city sets (with minimum timing rules). See Chapter 17.96 for the specifics. § 17.96.010–120.
