Jurupa Valley — Nonconforming Uses

Nonconforming Uses under the Jurupa Valley local zoning and planning code, with the controlling citations.

Last reviewed: July 2, 2026

Overview

This page explains how Jurupa Valley treats nonconforming uses, nonconforming structures, and nonconforming lots under the city zoning ordinance (Title 9). The primary rules are codified in § 9.240.080 (Nonconforming structures and uses) and the term definitions in § 9.10.900–§ 9.10.930; these provisions set verification, time limits (amortization), expansion limits, reconstruction rights, and the certification process after the 2017 General Plan rezoning. See the city's zoning title for procedure details on hearings, variances, and site permits. § 9.240.080 is the controlling nonconforming-use rule .

First, a few useful links for related topics mentioned on this page: the city's Jurupa Valley Zoning overview, Jurupa Valley Development Standards for setbacks and height, Jurupa Valley Parking for off-street parking rules, Jurupa Valley Design Review for discretionary design checks, Jurupa Valley Overlay Districts for special overlays, Jurupa Valley ADUs for accessory-unit interaction with nonconforming zoning, Jurupa Valley Variances and Exceptions for relief options, and the state California Building Standards Code (Title 24) when work triggers building-code compliance.

All policy text below is an original synthesis of the city's ordinance language; specific quotes are not reproduced verbatim — see the cited sections for exact statutory wording.

Where the nonconforming rules live (short view)

Definitions: § 9.10.900 (Nonconforming building) and § 9.10.910 (Nonconforming use) .
Substantive rules (verification, durations, expansion, reconstruction, amortization extensions): § 9.240.080 and cross-references to § 9.240.250 (hearing procedures) and § 9.240.560 (automobile fueling station special rules) .
Special neighborhood/zone rules referenced within individual zone chapters (e.g., C-T, C-N, R-3): see each zone chapter cited below for where nonconforming uses would be evaluated under local development standards (sample citations follow in district subsections) .

Core rules you must know (synthesized, with controlling citations)

Verification and Certificate: Property owners may apply in writing to the Community Development Director to verify a nonconforming status; the application must include a fee, parcel/APN, site plan, photographs, prior and current zoning info, written justification, and supporting continuous-use documentation. If substantiated, the Planning Department issues a Certificate of Nonconforming Use listing APN, address, nature of the nonconformance, and expiration (if any) § 9.240.080(2) .
Maintenance vs. Structural Alteration: Nonconforming structures/uses may be continued and maintained without structural alteration except as the code allows; agricultural crops are excepted (per the ordinance) § 9.240.080(1) .
Time limits (amortization / loss of nonconforming right): The ordinance establishes different maximum maintenance periods depending on use type (unimproved land, minor improvements, outdoor advertising, commercial and industrial, and many agricultural categories). For many general commercial uses the amortization/loss period is one (1) year; certain industrial and manufacturing uses and some commercial uses have longer amortization windows (commonly forty (40) years for many M zones and for general manufacturing), and outdoor advertising and many agricultural uses have other specified durations. See § 9.240.080(3) for the full timetable and breakdown .
One-year discontinuance rule (general): If a nonconforming use is discontinued for one (1) year or more, the nonconforming right is lost unless a special timetable elsewhere in the subsection applies § 9.240.080(7) .
Expansion cap: A nonconforming structure/use may be enlarged on the same parcel by up to 25% (excluding mobilehomes). Such expansion requires a building permit only and does not extend the amortization period § 9.240.080(5) .
Reconstruction after damage: A nonconforming structure damaged by fire, explosion, or acts of God may be repaired, rebuilt, or replaced and continued in use, but rebuilding does not restart or extend the required amortization/elimination period § 9.240.080(9) .
Completion of previously permitted construction: If a building permit was legally issued and substantial work occurred prior to an amendment that made the use nonconforming, the project may nevertheless be continued and completed under the previously issued permit § 9.240.080(8) .
Extensions for commercial/industrial amortization: Where commercial or industrial uses exceed the standard amortization periods, the city may grant an amortization extension up to a total additional ten (10) years after the procedures set in § 9.240.080(4) (application, fee, site plan, photographs, hearing under § 9.240.250, and findings ensuring no threat to public health, safety, or welfare) § 9.240.080(4) .
Special rules for automobile fueling stations: Automobile fueling station uses have specific treatment: they are legal nonconforming where lawfully operating and, in general, are subject to the standard nonconforming rules except for particular limitations on re-establishment after discontinuance (e.g., 12 months for re‑establishment), and a 40-year amortization period is called out for fueling-station uses § 9.240.080(3)(d) and Sec. 9.240.560 for station-specific mod/rehab rules .
General Plan / rezoning exception and certification: When the city adopted the 2017 General Plan and concurrently changed zones for consistency, the code provides that lawful pre-existing uses shall not be made nonconforming by that change — the city will certify such pre-existing uses and recordable certifications may be issued; these certified pre-existing uses remain permitted until discontinued for over one (1) year or converted to another use § 9.240.080(12)–(13) .

District-by-district breakdown (how nonconforming rules intersect common zones)

Below are selected Jurupa Valley zones from the ordinance. For each zone I list the zone purpose, typical permitted uses, representative dimensional/development standards, and where the zone rules appear so you can cross-check how a nonconforming use would be evaluated in that zone.

Risks & Ambiguities

Issue	Why it matters	What to verify
Variable amortization by use	Different uses have widely different time periods (1 yr → 40 yrs). Mis‑classifying a use can lead to unexpected loss of rights.	Confirm exact use classification and applicable amortization bracket in § 9.240.080(3) and the zone chapter for permitted/conditional uses § 9.240.080(3) .
Fueling‑station exceptions	Auto fueling stations have separate re‑establishment, rehabilitation, and amortization rules (and environmental/engineering constraints).	Verify both § 9.240.080(3)(d) and § 9.240.560 for fueling‑station specifics and consult Environmental/Public Works for remediation or stormwater requirements .
Whether a particular change is a "structural alteration"	Structural alteration prohibition limits permitted work; some safety/Title 24 work may require structural changes.	Read the structural‑alteration language in § 9.240.080(1) and check with Building Division (Title 24) for work that triggers code compliance § 9.240.080(1) .
2017 General Plan rezoning certification	The ordinance protects pre‑existing legally established uses when the city rezoned properties for GP consistency, but certification is required and may be recordable.	Check § 9.240.080(12)–(13) for certification procedure and whether a recordable certificate was issued for the parcel .
Expansion vs. new use	A modest enlargement (≤25%) is allowed; larger expansion or a change of occupancy to a different use may lose nonconforming protection.	Confirm expansion size in § 9.240.080(5) and that any change of use is evaluated against the zone's permitted uses and potentially requires a site development permit § 9.240.080(5) .

Plain-English Summary

If your property in Jurupa Valley currently operates in a way that no longer conforms to new zoning rules, you can often keep using it — but the city requires verification, limits how long certain nonconforming uses can continue (from one year up to forty years depending on the use), allows only limited expansion (generally up to 25%), and will revoke the right if the use stops for the statutory period. Start by applying to the Planning Department for a Certificate of Nonconforming Use and be prepared with a site plan, photos, proof of continuous use, and the APN — see § 9.240.080 for the full procedures and timeframes .

Frequently asked questions

What does the city consider a "nonconforming use" in Jurupa Valley?

A "nonconforming use" in Jurupa Valley is a use of land or a building that was lawful when established but conflicts with current zoning after an ordinance or zone change. The ordinance definitions for a nonconforming building and nonconforming use are in § 9.10.900 and § 9.10.910, and the treatment of those uses is governed by § 9.240.080 .

How do I prove my operation is a legal nonconforming use?

You must apply for a written determination to the Community Development Director with the required fee, APN, a detailed site plan, panoramic photos, current and prior zoning, written justification, and supporting documentation showing continuous use (utility bills, tax records, leases, business records). The application requirements are in § 9.240.080(2)(a–viii); if substantiated, the Planning Department issues a Certificate of Nonconforming Use § 9.240.080(2) .

How long can a nonconforming commercial use continue?

It depends on the use. Jurupa Valley lists specific periods by use in § 9.240.080(3) — typical general commercial uses in C zones are in a one (1) year category, while many manufacturing or industrial uses are given much longer periods (often forty (40) years) . Verify which bracket your use falls into in § 9.240.080(3).

Can I expand a nonconforming building or business?

Limited expansion is allowed: an existing nonconforming structure or use (excluding mobilehomes) may be enlarged up to 25% on the same parcel. Expansion requires a building permit and does not extend the nonconforming amortization period § 9.240.080(5) .

If my nonconforming structure is damaged, can I rebuild it?

Yes — the code allows reconstruction, repair, or replacement of a nonconforming structure damaged by fire, explosion, or acts of God; however, rebuilding does not extend the amortization/elimination clock for the nonconforming right § 9.240.080(9) .

What if the city rezoned my property during the 2017 General Plan update?

The code includes a special rule protecting lawful pre‑existing uses during the 2017 General Plan rezoning: a pre-existing legal use shall not be made nonconforming by the change of zone and may be certified as permitted/conditionally permitted until discontinued for more than one (1) year or converted to another use § 9.240.080(12–13) .

Can I get more time if my commercial or industrial use is facing amortization?

Potentially — Jurupa Valley allows amortization extensions for commercial/industrial uses beyond the standard periods, but the total extension cannot exceed ten (10) years and is subject to an application, public hearing (per § 9.240.250), and findings that the continued use will not harm public health, safety, or welfare § 9.240.080(4) .

Does the 25% expansion rule apply to accessory dwelling units (ADUs)?

ADU-specific rules are governed by state ADU law and local ADU rules; Jurupa Valley's nonconforming expansion rule for nonconforming structures (25%) applies generally to nonconforming structures § 9.240.080(5), but state ADU provisions may limit the city's ability to condition ADU approval on correction of certain zoning nonconformances — consult the local ADU chapter and state ADU law; see Jurupa Valley ADU guidance and § 9.240.080(5) and Jurupa Valley ADUs.

Do I need a public hearing to get an extension or to verify nonconforming status?

Verification/certificates are administrative but the Planning Department must review and will issue a certificate or denial with notice; an amortization extension for commercial/industrial uses requires a public hearing in accordance with § 9.240.250 § 9.240.080(2–4) .

What happens if I change my use to a conforming use and later want back the old nonconforming use?

If a nonconforming portion of a property is changed or replaced by a use that conforms to the code, it may not thereafter revert back to a nonconforming use § 9.240.080(6) .
