Woodlake — Nonconforming Uses

Q: What is a nonconforming use in Woodlake?

A nonconforming use is a use that was lawfully commenced before the current Title 17 rules (or before annexation) but that no longer complies with the City's use regulations; see § 17.90.030 .

Q: If a building is 60% destroyed in a fire, can I rebuild it as it was?

If a nonconforming structure is destroyed to an extent of 50% or more of its structural mass, it may not be restored except in full compliance with current Title 17 requirements; for destruction less than 50% the structure may be rebuilt and retain nonconforming status. The building official determines the percentage. See § 17.90.080(A–B) .

Overview

This page summarizes how the City of Woodlake handles nonconforming uses, nonconforming structures, and nonconforming lots under the local zoning ordinance (Title 17). It explains the legal definitions, limits on change/repair/expansion, abandonment rules, and special rules for overlays and unique uses — grounded in the City's ordinance text. See the City's general zoning rules for context in the Woodlake zoning overview and the land-use tables.

What the ordinance says (core rules)

Purpose: the ordinance acknowledges existing lawful-but-now-noncompliant situations should be allowed to continue but not encouraged to expand. See § 17.90.010.
Applicability: the nonconforming chapter applies to uses, structures, and lots lawful when commenced but that currently conflict with Title 17 (nonconforming signs are handled separately in Chapter 17.56). See § 17.90.020.
When a use is nonconforming: a use lawfully started before adoption/amendment of the zoning rules or lawfully started while under county jurisdiction and annexed into the city may be nonconforming. See § 17.90.030(A–B).
Parking exception: a use is NOT a nonconforming use if the only deficiency is failure to meet on‑site parking or loading minimums. See § 17.90.030(C).
Nonconforming structures: structures legally erected earlier but that now violate the zoning standards are nonconforming; they may be repaired but generally may not be moved/expanded so as to increase nonconformity (coverage, setbacks, height, spacing) except as allowed by the chapter. See § 17.90.040(A–D).
Nonconforming lots: a lot legally created before the code change that does not meet current lot standards is a nonconforming lot; it cannot be subdivided or have lot lines adjusted to create new nonconformities, but may be used for any use allowed in the underlying zone and can have a conforming structure built on it. See § 17.90.050(A–D).
Abandonment / discontinuance: a nonconforming use that is abandoned, discontinued, or changed to conforming for a continuous period of one (1) year loses its nonconforming status and cannot be reestablished thereafter. See § 17.90.060(A).
Agricultural exception: an agricultural crop production use rendered nonconforming by annexation or ordinance change may continue but the intensity may not increase. See § 17.90.060(B).
Limited expansion / reestablishment via Conditional Use Permit (CUP): a nonconforming use may be expanded up to 10% of existing floor area if a CUP is granted; an expansion of that nature may be allowed only one time per use. A nonconforming use discontinued for more than one year but less than two years can be reestablished with a CUP. See § 17.90.070(A–B).
Restoration after damage: if a nonconforming structure is destroyed by ≥ 50% of its structural mass it generally may not be restored except in full compliance with current standards; if damage is < 50% it may be rebuilt and remain nonconforming (building official determines percent). Residential nonconforming residential structures may be rebuilt in their original location notwithstanding the 50% rule. See § 17.90.080(A–C).
Removal on violation: certain low-value or non-structure occupying nonconforming uses must be removed within 30 days of violation notice unless an alternative is given. See § 17.90.090(A–C).
Eminent domain: loss of lot area triggers nonconforming lots/structures rules but not nonconforming-use rules; reduction of a required yard or parking by eminent domain can create a nonconforming structure but parking loss alone does not automatically create nonconforming use status. See § 17.90.100(A–C).
Changing one nonconforming use to another nonconforming use is allowed only by CUP and only if findings protecting zone character, traffic, nuisance levels, and public health/safety can be made. See § 17.90.110(A–B).

The City’s Development Standards chapter applies to all zones and therefore interacts with nonconforming-structure questions (repairs, setbacks, nuisances, landscaping). See Chapter 17.50 for standards that remain applicable.

For procedural steps that usually accompany repairs, expansions, or changes of nonconforming structures, expect site plan review and the CUP process (see the Director/Planning procedures in Chapter 17.72 and Chapter 17.80). See the City's site-plan and design-review rules for thresholds that trigger discretionary review.

District-by-district (where nonconformity rules most commonly appear)

Below are Woodlake districts where nonconforming issues most often arise; each subsection lists the district name (bolded), the purpose, typical uses, and key dimensional standards that matter when evaluating whether a building or lot is nonconforming.

R‑VL (Very Low‑Density Residential)

Purpose: transition between urban and agricultural areas; density 0.1–3 dwellings/acre. See § 17.12.010.
Typical permitted uses: single‑family dwellings and specific residential uses as listed in the residential land‑use table (see Table 17.08.020‑1).
Key dimensional standards: minimum lot area 15,000 sq ft, frontage 40 ft, max lot coverage 40%, max height 35 ft and parking requirements for single‑family dwellings (two covered spaces). See §§ 17.12.030, 17.12.040, 17.12.060, 17.12.130.
Where it applies: defined on the City zoning map; a residential structure legally built under earlier rules that now violates one of the above standards is a nonconforming structure under § 17.90.040 and repair/expansion rules apply.

R‑L (Low‑Density Residential)

Purpose and uses: standard single‑family and related residential uses; uses per Table 17.08.020‑1. See § 17.14.020.
Key dimensional standards: minimum lot area 5,000 sq ft, front setback 15 ft (20 ft to garage/carport), rear 15–20 ft, side 5–10 ft, max height 35 ft, max coverage 40%. See §§ 17.14.030–17.14.090.
Nonconforming note: a prior‑built home that now encroaches into today's required front/side/rear setbacks is a nonconforming structure; expansion that increases the nonconformity is generally prohibited except as allowed by the nonconforming chapter (repairs allowed; limited expansion via CUP only per § 17.90.070).

C‑S (Service Commercial)

Purpose: commercial service uses serving neighborhoods/region. See § 17.22.010.
Typical uses and controls: uses listed in 17.08.030; setbacks and parking standards vary — front setback 10 ft, side/rear can be 0 ft in many cases, height up to 40 ft, landscaping and screening rules apply. See §§ 17.22.020–17.22.080.
Nonconforming note: nonconforming commercial operations are governed by § 17.90.030; the code explicitly excludes lack of required parking alone from qualifying a use as nonconforming (see the parking exception in § 17.90.030(C)).

I (Industrial)

Purpose: manufacturing, wholesale, storage. See § 17.28.010.
Key dimensional standards: minimum site area for new lots 20,000 sq ft (existing smaller sites allowed), front setback 15 ft, side/rear 10 ft, height 75 ft (exceptions exist). See §§ 17.28.030–17.28.080.
Nonconforming note: industrial structures rendered nonconforming by zoning changes are subject to the general nonconforming-structure rules; expansions or new structures that would contribute to a nonconforming use are disallowed except as in § 17.90.040(E) and § 17.90.090.

PF (Public Facilities)

Purpose: locations for public and institutional uses including the airport and utilities. See § 17.30.010.
Key standards: no minimum lot area for PF, setbacks and coverage follow Chapter 17.50 standards; height up to 50 ft; parking per Chapter 17.54. See §§ 17.30.030–17.30.080.

Downtown Overlay (Design/Downtown Overlay Zone)

Purpose: protect and promote a pedestrian‑oriented, well‑designed downtown; overlay design guidelines and chapter apply in addition to base zone rules. See § 17.36.010–020.
Nonconforming interaction: overlay requirements take precedence where they conflict with base‑zone rules (see § 17.36.020(B)); minor building improvements may be exempt from downtown design review (see § 17.36.090), but nonconforming buildings in downtown are still subject to Chapter 17.90 constraints.

Airport Overlay

Purpose: protect airport operations and safety; special height, use, and nonconforming rules apply. See § 17.34.010–030.
Nonconforming trees/structures: airport overlay explicitly prohibits increasing nonconformity (e.g., raising a nonconforming height) and allows existing nonconforming structures/trees to remain but may require marking/lighting for safety. See § 17.34.030–040.

Quick Reference table (decision‑relevant standards and code references)

Topic / standard	Rule / limit	Code Reference
Definition: nonconforming use	Lawful when established but now violates Title 17	§ 17.90.030
Loss of status after discontinuance	Continuous 1 year discontinuance = loss of legal nonconforming status	§ 17.90.060(A)
Limited expansion	Up to 10% floor area increase by CUP, only one time	§ 17.90.070(A)
Reconstruction after damage	Destruction ≥ 50% structural mass → cannot restore as nonconforming (exceptions for residences)	§ 17.90.080(A–C)
Nonconforming lots	May be used for any use allowed in the zone; cannot be subdivided to create new nonconformities	§ 17.90.050(A–D)
Parking-only deficiency	Parking shortage alone does NOT create a nonconforming use	§ 17.90.030(C)
Site plan review threshold for nonconforming building changes	Alterations increasing floor area of a nonconforming building typically trigger site plan review	Chapter 17.72 (site plan review)

Practical guidance / interpretation (plain language, ordinance‑based)

If your building or use was legal when established but now violates a setback, height, or use rule, it is a nonconforming structure/use/lot under § 17.90.030–050.
You may perform routine maintenance and repairs on a nonconforming structure without losing status, but you generally may not enlarge it so the nonconformity increases (for example, cantilever a building further into a required setback) — see § 17.90.040(B–D).
If you want to expand a nonconforming commercial or other use, plan for a CUP and know the ordinance caps the one‑time expansion at 10% of existing floor area; the CUP findings must support compatibility with the zone. See § 17.90.070 and § 17.90.110.
If a nonconforming building was badly damaged, the 50% rule is critical: less than 50% loss → rebuild and retain nonconforming status; 50% or greater → must rebuild to current code, except residential structures may be rebuilt in place per § 17.90.080. Have the building official confirm the percentage.

Linking to related topics you will commonly need:

If changes involve dimensional standards consult the City's development standards.
If you are changing site layout or parking, check parking limits and the parking exception in the nonconforming chapter.
Projects that alter nonconforming buildings often trigger design review or site‑plan review (see Chapter 17.72).
If the property is inside an overlay, read the overlay districts rules (Downtown, Airport) because overlay rules can override base zone provisions.
If you plan an Accessory Dwelling Unit (ADU) on a nonconforming property, review the City's ADU rules and state ADU law; the City’s ADU rules are at Woodlake ADUs and state law contains protections for ADUs built on nonconforming lots/structures.
Structural repairs that intersect with building-safety questions also involve the California Building Standards Code; verify with the building official for restoration thresholds.

Checklist (what an applicant must satisfy when working on a nonconforming use/structure/lot)

Confirm whether the use/structure/lot was lawful when established (document title/permits/assessor records). See § 17.90.020.
Determine whether the condition is a nonconforming use, structure, or lot per §§ 17.90.030–050.
If proposing expansion: calculate proposed floor‑area increase and prepare a Conditional Use Permit application if increase ≤ 10% (one-time limit) — see § 17.90.070 and Chapter 17.80 for CUP procedures.
If the structure was damaged, obtain building official determination of percent structural mass destroyed (<50% vs ≥50%) and follow § 17.90.080 guidance.
For alterations that increase floor area or involve nonconforming buildings, expect site plan review and possibly design review — follow Chapter 17.72.
If property is in an overlay (Downtown or Airport), check overlay rules — overlay may supersede base zone rules. See § 17.36.020(B) and § 17.34.030.
Check parking rules: lack of parking alone does not make a use nonconforming, but parking requirements still apply for new work; consult Chapter 17.54. See § 17.90.030(C).

Risks & Ambiguities

Issue	Why it matters	What to verify
Whether a use was "lawfully commenced"	Only lawfully commenced uses can claim nonconforming status; undocumented or unpermitted uses may not qualify	Verify historical permits, business licenses, annexation dates, and county permits. See § 17.90.020–030.
Abandonment clock (1 year)	Continuous discontinuance >1 year eliminates nonconforming status and bars reestablishment	Confirm last date of operation and evidence of activity. See § 17.90.060(A).
The 50% destruction test	Determines whether rebuilding must meet current standards or can be restored as nonconforming	Secure a building official determination of % structural mass destroyed. See § 17.90.080(A–B).
What counts as "increase in intensity" for agricultural uses	Agricultural uses are permitted to continue but cannot increase intensity after annexation	Verify crop/operation intensity baseline and confirm restrictions per § 17.90.060(B).
Data used to measure expansion (floor area)	Ordinance caps expansion at 10% — calculating base area matters to whether CUP is needed	Document existing floor area (as-built or permitted), and use that baseline for the § 17.90.070 calculation.
Overlay conflicts (Downtown/Airport)	Overlay standards may impose stricter limits or different restoration rules	Confirm overlay boundaries and which overlay chapter applies; see § 17.36.020(B) and § 17.34.030.

Plain‑English Summary

If your Woodlake property was legal when it was built or your business started but no longer meets today's zoning rules, it's treated as a nonconforming lot/structure/use under Chapter 17.90. You can usually maintain and repair it, but you generally cannot expand the nonconformity (expansions require a CUP and are tightly limited) and if the use stops for a year you lose the right to resume the nonconforming use. See the specific rule citations above for the exact thresholds and exceptions.

Frequently asked questions

What is a nonconforming use in Woodlake?

A nonconforming use is a use that was lawfully commenced before the current Title 17 rules (or before annexation) but that no longer complies with the City's use regulations; see § 17.90.030.

If my house sits inside today's setback, can I repair or expand it?

You can perform routine maintenance and repairs on a nonconforming structure (allowed by § 17.90.040(D)), but enlarging it in a way that increases the nonconformity (e.g., building further into a required setback) is generally prohibited unless the change brings the structure into compliance or is otherwise authorized under the nonconforming chapter. See § 17.90.040(B–C).

How long before a nonconforming business loses its rights if it stops operating?

If a nonconforming use is abandoned, discontinued, or changed to conforming for a continuous period of one (1) year, it cannot be reestablished and the property must thereafter conform to current zoning. See § 17.90.060(A).

Can I add an ADU on a nonconforming lot or structure?

State ADU rules and the City's ADU rules affect this; Woodlake allows ADUs but state law limits denial for nonconforming zoning conditions in many cases. Consult the City's ADU rules and the state ADU guidance; see the City ADU chapter and the nonconforming definitions. City ADU guidance: § 17.60 (see City ADU page) and nonconforming protections are in § 17.90.050–080; check also state ADU law. Not all specifics are in the retrieved local materials — verify with the planning department.

If a building is 60% destroyed in a fire, can I rebuild it as it was?

If a nonconforming structure is destroyed to an extent of 50% or more of its structural mass, it may not be restored except in full compliance with current Title 17 requirements; for destruction less than 50% the structure may be rebuilt and retain nonconforming status. The building official determines the percentage. See § 17.90.080(A–B).

Can a nonconforming use be changed to a different nonconforming use?

Yes, but only with a Conditional Use Permit, and only if the approving authority finds the proposed use will not alter the zone’s character, increase vehicle traffic, create greater nuisances (noise, odor, glare), or be detrimental to public health, safety or nearby property. See § 17.90.110(A–B).

Does lack of required parking automatically make my business nonconforming?

No. If the only deficiency is failure to meet the minimum on‑site parking or loading, the use is not considered nonconforming. See § 17.90.030(C). However, parking requirements still apply to new work.

Where do I find the standards (setbacks, height) I must meet if I lose nonconforming rights?

Setbacks, heights, coverage, and other development standards are in each zone chapter and in Chapter 17.50 (Development Standards). If you are rebuilding to comply, apply the standards in the underlying zone (for example, § 17.12 for R‑VL, § 17.14 for R‑L, § 17.22 for C‑S, etc.).

If I'm inside the Downtown Overlay, do downtown rules or base zone rules apply?

Both apply; if there is a conflict the Downtown Overlay chapter controls. The Overlay also has design guidelines and may require design review except for minor improvements listed in § 17.36.090. See § 17.36.020(B) and § 17.36.090.
