Dos Palos — Nonconforming Uses
Nonconforming Uses under the Dos Palos local zoning and planning code, with the controlling citations.
Last reviewed: July 6, 2026
Overview
This page summarizes what the City of Dos Palos zoning ordinance (Title 17 Zoning) shows—and what is missing in the retrieved text—about nonconforming uses, structures, and lots. Key process articles and district chapters are present in the available materials, but explicit, citywide rules for continuation, expansion, alteration, damage/reconstruction, abandonment, and changes of nonconforming uses were not found in the retrieved excerpts. Where rules could not be confirmed in Title 17, this page flags them for verification with the City.
Related topics often come up together. If you’re here because a project triggered review, you may also need to look at the broader Dos Palos Zoning, the baseline Dos Palos Development Standards, possible Dos Palos Design Review, and site access/parking under Dos Palos Parking. For exceptions or relief, see Dos Palos Variances and Exceptions. Accessory units are governed by state law and a local ordinance—see Dos Palos ADUs—and construction is governed separately by the California Building Standards Code.
Plain-English anchor: If a use, structure, or lot was lawful when it began but no longer matches today’s zoning rules, it may be “nonconforming.” Dos Palos’ Title 17 excerpts retrieved here do not provide the citywide ground rules for how such nonconformities may continue, change, or be rebuilt. Verify with the jurisdiction.
What the retrieved Title 17 does and does not show
- Title 17 includes a full article on discretionary relief (Conditional Use Permits and Variances), which sets procedures, findings, appeals, and timelines. This is helpful when you’re exploring a path to compliance; however, a variance is different from a right to continue a nonconforming use, and the retrieved text does not tie the two together for nonconforming status. See Chapter 17.76 (Article I CUPs; Article II Variances) for process scaffolding (§§ 17.76.010–17.76.280) .
- Definitions confirm that “Commercial district” and “District” are defined terms in Title 17 (§ 17.08.580; § 17.08.740), but the nonconforming definitions or rules are not present in the retrieved excerpts (§§ listed in the Definitions chapter index) .
- The code contains district chapters with development controls and “site plan review,” e.g., a district chapter at § 17.30.110 Site plan review and off-street parking at § 17.30.130; a second district chapter (starting § 17.32.010) shows a similar structure. Specific district names and their mapped locations are not visible in the retrieved text (§§ 17.30.010–17.30.130; §§ 17.32.010–17.32.060) .
State overlay for ADUs only:
- For accessory dwelling units, state law limits what a city may require when nonconforming zoning conditions exist (e.g., you generally can’t be forced to fix unrelated nonconforming conditions just to permit an ADU unless a health/safety threat is implicated). This is a state rule; it does not replace local nonconforming-use provisions for other projects (Gov. Code §§ 66322(b), 66323(c)) .
Citywide nonconforming-use mechanics (what to verify)
Because the controlling provisions did not appear in the retrieved Title 17 text, each item below is a verification prompt:
- Continuation of lawful nonconforming uses: Not found in retrieved materials.
- Enlargement/intensification of a nonconforming use: Not found in retrieved materials.
- Change from one nonconforming use to another: Not found in retrieved materials.
- Repair, maintenance, and structural alterations to nonconforming structures: Not found in retrieved materials.
- Destruction thresholds (fire/other casualty) and rebuild rights or limits: Not found in retrieved materials.
- Abandonment or discontinuance periods that terminate nonconforming rights: Not found in retrieved materials.
- Nonconforming lots (lot area/width deficiencies) and development allowances: Not found in retrieved materials.
- Proof of legality (establishing a use/structure/lot was lawful when created): Not found in retrieved materials.
- Required permits or findings to modify, expand, or replace a nonconforming condition: Not found in retrieved materials.
Where process relief is needed (and allowed by code), the City’s variance/CUP procedures in Chapter 17.76 provide the hearing, findings, and appeal framework, but they do not themselves create nonconforming rights (§§ 17.76.010–17.76.280) . For site design and dimensional compliance generally, cross-check the relevant district chapter (e.g., §§ 17.30.040, 17.30.110–.130; §§ 17.32.040–.060) and applicable Dos Palos Development Standards.
District-by-district notes on nonconforming conditions
The retrieved text lists district chapters with section headings but does not show the district names, mapped boundaries, or any nonconforming-use sections within those chapters. Use this as a guide to where to look; do not rely on it as a substitute for the full chapter text.
Chapter 17.30 district chapter (name not visible in retrieved text)
- Purpose and permitted uses: Not found in retrieved materials (see § 17.30.010; § 17.30.020) .
- Key dimensional standards: Not found in retrieved materials (see § 17.30.040; §§ 17.30.050–.100) .
- Procedures affecting projects: Site plan review (§ 17.30.110) and off-street parking (§ 17.30.130) are listed; confirm content and thresholds in the full text (§§ 17.30.110, 17.30.130) .
- Nonconforming-use rules that tailor to this district: Not found in retrieved materials.
Chapter 17.32 district chapter (name not visible in retrieved text)
- Purpose and permitted uses: Not found in retrieved materials (see § 17.32.010; § 17.32.020) .
- Key dimensional standards and height: Not found in retrieved materials (see § 17.32.040; § 17.32.050) .
- Procedures: Site plan review (§ 17.32.060) is listed; verify applicability thresholds (§ 17.32.060) .
- Nonconforming-use rules that tailor to this district: Not found in retrieved materials.
Citywide defined terms that affect districts
- The code defines Commercial district (§ 17.08.580) and District (§ 17.08.740), confirming that Title 17 organizes rules by mapped districts; district-specific nonconforming rules, if any, were not found in the retrieved text (§§ 17.08.580, 17.08.740) .
Table — Decision-relevant checkpoints for nonconforming status
| Topic | What to look for in Title 17 | Code Reference |
|---|---|---|
| Continuation of a lawful nonconforming use | Whether continuation is allowed; limits on hours, intensity, or operations | Not found in retrieved materials |
| Expansion of a nonconforming use or structure | Whether expansions are prohibited, capped, or allowed with permits | Not found in retrieved materials |
| Change to another nonconforming use | Whether a swap to a different nonconforming use is allowed and on what findings | Not found in retrieved materials |
| Damage and reconstruction | Threshold (e.g., percent of value) and timelines to rebuild to nonconforming status | Not found in retrieved materials |
| Abandonment/discontinuance | The period (months/years) after which nonconforming rights terminate | Not found in retrieved materials |
| Nonconforming lots | Ability to develop substandard lots; required lot-merge or findings | Not found in retrieved materials |
| Required approvals | Whether CUP, site plan review, or variance is required to modify a nonconformity | Process scaffolding exists in Chapter 17.76 (CUPs/Variances) — content retrieved; verify applicability to nonconforming cases (§§ 17.76.010–17.76.280) |
Note on ADUs only: If your “nonconforming” issue arises during an ADU application, state law has special protections regarding existing nonconforming zoning conditions (Gov. Code §§ 66322(b), 66323(c)) . This is separate from (and does not establish) nonconforming rights for other project types.
Checklist
- Confirm the property’s zoning district and overlay, using the City’s maps and the applicable district chapter (e.g., §§ 17.30.010–.130; §§ 17.32.010–.060) and Dos Palos Zoning.
- Assemble proof the use/structure/lot was lawful when established (permits, COs, dated aerials). Code basis for proof standards: Not found in retrieved materials.
- Identify which part is nonconforming (use, structure, lot) and why (setbacks, height, use tables, lot area).
- Check for district-specific rules on nonconforming situations. Not found in retrieved materials—Verify with the jurisdiction.
- If any modification is proposed (expansion, replacement, change of use), confirm whether CUP, variance, or other approval is required under Chapter 17.76 (procedures and findings) (§§ 17.76.010–17.76.280) .
- If the project includes an ADU, apply state ADU nonconforming protections separately (Gov. Code §§ 66322(b), 66323(c)) and see Dos Palos ADUs .
- Coordinate parallel compliance on site design, parking/loading, and any required plan/design reviews (e.g., § 17.30.110 site plan review; § 17.30.130 parking) and Dos Palos Design Review / Dos Palos Parking .
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| No retrieved chapter on nonconforming uses | Without explicit rules, you cannot assume rights to continue, expand, or rebuild | Ask Planning for the current nonconforming-use chapter or sections; confirm any amortization, abandonment, or rebuild thresholds. Not found in retrieved materials. |
| District-specific carve-outs | Some cities tailor nonconforming rules by district; the retrieved excerpts show district chapters but not their full content | Confirm if any districts loosen or tighten nonconforming allowances (e.g., downtown/commercial cores). Not found in retrieved materials; see §§ 17.30, 17.32 indices for where to look . |
| Using variances to “legalize” a prohibited use | Variances are a different legal tool than nonconforming status; misapplying them can lead to denial | Review Chapter 17.76 procedures and findings; ask staff if variances can modify nonconforming structures versus authorize uses (§§ 17.76.010–17.76.280) . |
| ADU applications on nonconforming sites | State law often prevents denial based solely on unrelated zoning nonconformance | Apply Gov. Code §§ 66322(b), 66323(c) during ADU review and document any health/safety nexus. This is separate from local nonconforming rules for other project types . |
| Proof the prior condition was lawful | Nonconforming status usually requires proof of legality | Ask what evidence the City accepts to establish legality at time of creation. Not found in retrieved materials. |
Plain-English Summary
Dos Palos’ zoning code excerpts show where you’ll find district rules and how hearings/variances work, but they don’t show the city’s actual “nonconforming use/structure/lot” rules. Before you spend on design, verify with Planning whether and how a nonconforming use can continue, expand, change, or be rebuilt—and for ADUs, remember state law gives special protection against denials based on unrelated zoning nonconformities.

Frequently asked questions
Does Dos Palos allow a legal nonconforming use to continue indefinitely?
Not found in retrieved materials. Many cities allow continuation if the use was lawful when established, but the Dos Palos rules (time limits, abandonment, amortization) were not visible here. Verify with the jurisdiction.
Can I expand a nonconforming building in Dos Palos?
Not found in retrieved materials. Expansion is often limited or requires discretionary approval. You may need to consult Chapter 17.76 for the applicable permit process while you confirm whether expansion is allowed for nonconforming structures (§§ 17.76.010–17.76.280) .
If my nonconforming building is damaged by fire, can I rebuild to the same footprint?
Not found in retrieved materials. Some cities allow rebuilding within a time/percentage threshold; the retrieved Title 17 excerpts do not state Dos Palos’ rule. Verify with the jurisdiction.
Can I change from one nonconforming use to another (e.g., nonconforming retail to nonconforming office)?
Not found in retrieved materials. Check whether the code allows “change of nonconforming use” and if findings are required. If a hearing is needed, the process would run through Chapter 17.76 (§§ 17.76.010–17.76.280) .
Do I need design or site plan review if I alter a nonconforming structure?
Possibly. A district chapter lists “site plan review” at § 17.30.110; confirm thresholds and whether nonconforming alterations trigger it (§ 17.30.110) . See also Dos Palos Design Review.
How do ADU applications interact with nonconforming zoning conditions in Dos Palos?
State law provides specific protections: a city generally may not deny an ADU solely because of unrelated nonconforming zoning conditions unless there’s a documented health/safety threat (Gov. Code §§ 66322(b), 66323(c)) . See Dos Palos ADUs.
Where do I find district-specific development standards that might affect my nonconforming situation?
Use the district chapters (e.g., §§ 17.30.010–.130; §§ 17.32.010–.060) to confirm setbacks, height, and parking—then ask Planning for the nonconforming section that applies in that district (headings retrieved, full content not shown) .
If I need relief, which chapter governs hearings and findings?
Chapter 17.76 provides the procedures for conditional use permits and variances, including findings, hearings, and appeals (§§ 17.76.010–17.76.280) . This chapter is procedural—it does not itself grant nonconforming status.
