Chula Vista — Nonconforming Uses
Nonconforming Uses under the Chula Vista local zoning and planning code, with the controlling citations.
Last reviewed: July 6, 2026
Overview
Chula Vista regulates nonconforming situations under Title 19 Planning and Zoning, primarily in Chapter 19.64, which calls them “previously conforming” uses and structures. The City’s policy is to bring such uses/structures into compliance, discontinue them, or remove them, with limited exceptions and processes to continue, expand, repair, or replace where appropriate (§ 19.64.010; ). Key dates and timelines matter: many definitions trace to uses/structures lawfully established before July 8, 1969, and specific time limits apply to abandonment and reconstruction (§§ 19.64.020, 19.64.080, 19.64.170; ).
Plain-English anchor: If a nonconforming (previously conforming) use or structure stops for 12 consecutive months, you generally lose the right to restart it; a short extension for hardship is possible (§§ 19.64.080, 19.64.220; ).
Linking context for applicants: see the City’s zoning basics, land use framework, development standards, parking, and design review. If an overlay or specific plan governs your site, also review overlay districts.
What “Previously Conforming” Means and How It Works
Definitions and policy:
- “Previously conforming use”/“previously conforming structure” are City terms for uses/structures that were compliant when created but do not meet current zoning due to later changes (§ 19.64.020; ). Title 19 also defines “nonconforming use/structure” anchored to July 8, 1969 (§ 19.04.002; ).
- City policy favors compliance or discontinuance, with tailored exceptions in Chapter 19.64 (§ 19.64.010; ).
Continuation (uses):
- A previously conforming use may continue only if it does not endanger public welfare, has not been abandoned, is documented as previously conforming, and has not since been brought into conformance (§ 19.64.030; ).
Expansion (uses):
- Expansion may be allowed if the Zoning Administrator finds the use is a long-term/traditional site use and compatible with surroundings; if allowed, it must meet applicable performance standards and follow the specified approval path (§§ 19.64.040–19.64.060; ).
Outdoor uses:
- If a previously conforming use is required by its zone to be enclosed or screened and is not, it must obtain site/architectural approval or be abated within 60 days of notice (§ 19.64.070; ). This often intersects with design review.
Abandonment (uses):
- A previously conforming use is deemed abandoned if ceased for 12 consecutive months; an active construction permit and business license can prove no abandonment during diligent repair/remodel/reconstruction; the Director may extend once, up to six months, for demonstrated regional economic hardship (§ 19.64.080; ).
Continuation, expansion, repair, replacement (structures):
- Structures may continue if safe, not abandoned, documented, and not brought into conformance (§ 19.64.090; ).
- Expansion is allowed without increasing the existing setback intrusion or height exceedance, and with code compliance otherwise; processing follows § 19.14.582(A) or (G) (§§ 19.64.120–19.64.130; ).
- Repair/maintenance is allowed; structural alterations are limited to what law requires or what’s authorized by Chapter 19.64 (§ 19.64.140; ).
- Replacement after calamity:
- Residential units may be reconstructed subject to § 19.64.170 (§ 19.64.150; ).
- Nonresidential structures may be reconstructed subject to § 19.64.170; not in the public right‑of‑way (§ 19.64.160; ).
- Conditions include: apply for building permits within six months; reach substantial completion within two years; meet then-current building codes; and stay within the existing footprint (§ 19.64.170; ). For building code context, see the California Building Standards Code.
Reconstruction permits and findings:
- A reconstruction permit is required; approval requires findings that the project won’t be detrimental, won’t increase the nonconforming aspect, that site constraints create undue hardship to conform, and that the prior use will continue (§§ 19.64.180–19.64.190; ).
- The Director may modify certain requirements where nonconformity is solely yards/height and may waive current setbacks/landscaping based on hardship if no detrimental impacts result (§ 19.64.210; ).
Abandonment (structures):
- A previously conforming structure is deemed abandoned if unoccupied for 12 months; a construction permit and business tax certificate can prove no abandonment during diligent repair; the Director may extend once up to six months for hardship (§ 19.64.220; ).
Performance standards overlay:
- Uses nonconforming as to performance standards (e.g., vibration, odor, glare) have five years to conform if established before July 8, 1969 (§ 19.66.050; ). Performance standards apply citywide, with measurement points differing inside/outside the industrial I zone (§ 19.66.060; ). See also § 19.66.020 (general prohibition of dangerous or objectionable elements) (§ 19.66.020; ).
Nonconforming lots (condemnation):
- Improved lots made nonconforming by condemnation are treated as conforming (with Planning Commission-authorized setback changes if needed for safety); vacant lots affected are nonconforming and require Zoning Administrator feasibility review before permits (§ 19.16.080; ).
Enforcement backdrop:
- Permits issued in conflict with Title 19 are void; uses contrary to Title 19 are unlawful and a public nuisance subject to abatement (§§ 19.08.010–19.08.020; ).

District-by-District Implications
This topic touches several districts because their baseline standards define when a use must enclose/screen, when setbacks apply, and how performance standards are enforced. For full zone context see the City’s zoning overview and development standards.
C‑N – Neighborhood Commercial
- Purpose/where it applies: Neighborhood shopping centers serving residential areas, typically on 3–8 acre sites (§ 19.34.010; ).
- Typical permitted uses: Grocery, drugstore, barber/beauty shop, small restaurant/café, offices, coin-op laundry (§ 19.34.020; ).
- Key dimensional/operational standards: Most uses must be fully enclosed; site/architectural approval required (§§ 19.34.080, 19.34.100; ).
- Nonconforming angle: Existing nonconforming shopping centers must be brought into conformance within one year of City notice (§ 19.34.230; ). Outdoor uses not meeting enclosure rules are subject to the 60‑day compliance/abatement path under § 19.64.070 .
C‑C – Central Commercial
- Purpose/where it applies: Business centers and corridors; mixed-use areas identified in the General Plan (§ 19.36.010; ).
- Typical permitted uses: Broad commercial and mixed-use activity (see Chapter 19.36 headings; ).
- Key dimensional/operational standards: Enclosure of uses is required with listed exceptions; additional setbacks and landscaping when across from an R zone (§§ 19.36.070–19.36.090; ).
- Nonconforming angle: Previously conforming outdoor activities may need to be enclosed or screened promptly after notice (§ 19.64.070; ). Additions that would intensify setback/height nonconformity are not allowed (§ 19.64.120; ).
I‑R – Research Industrial
- Purpose/where it applies: Modern, non‑nuisance research/specialized manufacturing areas (§ 19.42.010; ).
- Typical permitted uses: Labs, electronics manufacturing/assembly, related offices and warehousing (§§ 19.42.020–.030; ).
- Key dimensional/operational standards: Performance standards apply; screening/walls may be required (§§ 19.42.090, 19.42.180; ).
- Nonconforming angle: If a use is nonconforming to performance standards and predates 7/8/1969, it has five years to conform; field measurement points differ for industrial vs. other zones (§§ 19.66.050–.060; ).
I‑L – Limited Industrial
- Purpose/where it applies: Limited industrial areas buffered from nuisances (§ 19.44.010; ).
- Typical permitted uses: Light manufacturing, storage/warehousing, labs, vehicle sales/repair, materials yards (with conditions) (§ 19.44.020; ).
- Key dimensional/operational standards: Setbacks from residential or agricultural zones; performance standards apply (§ 19.44.110, 19.44.090; ).
- Nonconforming angle: Same time limits and performance standards conformance as above (§ 19.66.050; ).
I – General Industrial
- Purpose/where it applies: Areas for general industrial development, with protections for air/water and neighboring areas (§ 19.46.010; ).
- Typical permitted uses: Wide array of manufacturing, processing, trucking, storage (§ 19.46.020; ).
- Key dimensional/operational standards: Performance standards; setbacks from residential/agricultural zones; site plan/landscaping requirements (§§ 19.46.080–.120; ).
- Nonconforming angle: Performance standards are heavily enforced; measurement points for nuisances are set at 500 feet or zone edge for I zones (§ 19.66.060(B); ).
R‑E – Residential Estates (as a residential lens)
- Purpose/where it applies: Low‑density estate neighborhoods (§ 19.22; ).
- Typical permitted/conditional uses: Estate residential with limited conditionals (e.g., noncommercial recreation) (§ 19.22.040; ).
- Key dimensional standards: Residential setbacks/heights apply per district; previously conforming structures may expand only without increasing setback/height nonconformity (§ 19.64.120; ).
- Nonconforming angle: Home additions must not deepen encroachments or exceed existing nonconforming height; the 12‑month abandonment clock applies to uses/occupancy (§§ 19.64.120, 19.64.080, 19.64.220; ).
Cross‑references that often come up
- If your site is in a specific plan or overlay area (e.g., Bayfront), check that program’s objective standards—nonconforming handling may be affected by tailored setbacks, FAR, or view corridor rules; always confirm with overlay districts (Not found in retrieved materials for an overlay-specific nonconforming process).
- ADUs: State law limits denial based on correcting existing zoning nonconformities when reviewing ADUs; this is a state overlay on local zoning review (Gov. Code cited in HCD’s 2025 ADU Handbook) (See 2025 HCD ADU Handbook summary, Nonconforming Zoning, Gov. Code §§ 66322–66323; ). Verify with the jurisdiction.
Checklist
- Establish status: gather evidence the use/structure lawfully existed and became nonconforming due to later zoning changes (e.g., permits, occupancy records) (§§ 19.64.020, 19.64.030, 19.64.090; ).
- Confirm no abandonment: verify continuous operation/occupancy or maintain active permits/business license during repairs; note the 12‑month rule and possible single 6‑month extension (§§ 19.64.080, 19.64.220; ).
- For expansions of uses: prepare findings/evidence for long‑term/traditional use and compatibility; show performance standards compliance; file under the correct administrative track (§§ 19.64.040–.060; 19.66.020–.060; ).
- For structures: demonstrate no increase in setback/height nonconformity; follow the § 19.14.582 process; keep work within code (§§ 19.64.120–.130; 19.64.140; ).
- If rebuilding after damage: file for building permits within six months; reach substantial completion in two years; stay within footprint; secure a reconstruction permit with required findings (§§ 19.64.150–.190; ).
- If your use is out of step with performance standards: plan and document a path to conformance within applicable time limits (§ 19.66.050; ).
- If in C‑N and operating a nonconforming shopping center: track the City’s notice—full conformance is due within one year (§ 19.34.230; ).
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| Proof of “previously conforming” status | Without solid documentation, continuation/expansion rights may be denied | Collect dated permits, occupancy records, utility/lease history (§§ 19.64.030, 19.64.090; ) |
| 12‑month abandonment | Rights can be lost permanently | Track operating/occupancy continuity; if idle, keep active permits/licenses; ask about the one‑time 6‑month extension (§§ 19.64.080, 19.64.220; ) |
| Expansion of uses | Expansion is discretionary and must meet performance standards | Prepare a compatibility case; address vibration/odor/glare, etc. early (§§ 19.64.040–.060; 19.66.020–.100; ) |
| “No increase” to setback/height nonconformity | Additions that deepen encroachments won’t be approved | Design additions that stay within existing encroachments/height and meet all other standards (§ 19.64.120; ) |
| Rebuild timelines after damage | Missing the 6‑month/2‑year marks voids permits and can trigger abatement | Calendar deadlines; confirm “substantial completion” definition with staff (§ 19.64.170; ) |
| Specific plan/overlay constraints | Objective standards may override base zone details | Check applicable overlay districts; consult staff (Not found in retrieved materials) |
| C‑N amortization notices | One‑year compliance window runs from notice | Verify scope of required upgrades and schedule (§ 19.34.230; ) |
Plain-English Summary
If your property in Chula Vista has a use or building that was legal when created but no longer meets today’s zoning, you may keep it only if it isn’t abandoned, it stays safe, and you can prove its status. Expansions are possible but tightly controlled, especially for setback/height encroachments and any impacts like noise or odor. If a nonconforming activity stops for a year, or you miss the deadlines to rebuild after a disaster, your grandfathered rights likely expire (§§ 19.64.030–.080, 19.64.120, 19.64.150–.170; ).

Frequently asked questions
What does Chula Vista mean by “previously conforming”?
It’s the City’s term for a use or structure that was legal when established but doesn’t meet today’s zoning due to later changes. Chapter 19.64 allows limited continuation, expansion, repair, and replacement if strict conditions are met (§ 19.64.020; ).
How long can a nonconforming use sit idle before I lose it?
If a previously conforming use ceases for 12 straight months, it’s deemed abandoned. An active construction permit and business license can prove no abandonment during diligent repairs, and the Director may grant a one‑time 6‑month extension during regional economic distress (§ 19.64.080; ).
Can I add onto a house that encroaches a setback?
Often yes, if the addition does not increase the existing setback encroachment or height exceedance and meets all other rules. The approval follows § 19.14.582 processing (§§ 19.64.120–.130; ).
After a fire, can I rebuild my nonconforming commercial building?
Yes, if you apply for permits within six months and reach substantial completion within two years, meet current building codes, and don’t expand beyond the prior footprint. A reconstruction permit and specific findings are required (§§ 19.64.160–.170, 19.64.180–.190; ).
Do industrial nonconformities get special treatment?
Performance standards (vibration, odors, glare, etc.) apply citywide. Uses that were nonconforming as of July 8, 1969 have five years to conform, and measurement points for enforcement differ in the industrial I zone (§§ 19.66.050–.060; ).
What if my C‑N shopping center doesn’t meet today’s rules?
Once the City notifies you, you must bring the center into conformance within one year. Plan and budget upgrades accordingly (§ 19.34.230; ).
Do I need to enclose an older outdoor commercial use?
If your zone requires indoor operations or screening, a previously conforming outdoor use must get site/architectural approval or be abated within 60 days of notice (§ 19.64.070; ).
My lot became undersized due to condemnation—now what?
Improved lots reduced by condemnation are treated as conforming (setbacks may be adjusted for safety). Vacant lots made nonconforming require Zoning Administrator feasibility review before permitting (§ 19.16.080; ).
