Lake County — Variances and Exceptions

Variances and Exceptions under the Lake County local zoning and planning code, with the controlling citations.

Quick answer

In unincorporated Lake County, variances may relax development standards—but never authorize a use—and need Planning Commission approval with special‑circumstance findings that avoid special privilege (§ 21‑52.2; § 21‑52.5; § 21‑52.4); actions may be appealed within 7 days (§ 21‑58.30–58.36). Many items use exceptions instead: single‑story coverage to 40% on R‑1 lots under 6,000 sf (§ 21‑42.15(b)), tennis‑court fences over 6 ft (§ 21‑42.11(d)), and airport/riparian permits (§ 21‑39.9(c); § 21‑37.6). A denial bars refiling for 6 months (§ 21‑60.31).

Overview

This page explains how variances and exceptions work under the Lake County Zoning Ordinance in unincorporated areas. It focuses on when you can deviate from otherwise-required development standards (like setbacks, height, and lot coverage), what findings are needed, and the alternative “exception/adjustment” paths built into the code. For background on how zoning fits with the County’s overall system, see the Lake County zoning & planning overview and Lake County Zoning.

The most important rule: a variance can’t authorize a use that isn’t already allowed in the zoning district; it can only adjust development standards, and only with special-circumstance findings that avoid granting a special privilege. See § 21-52.2 and the three-part findings in § 21-52.5.

What counts as a “Variance” vs. an “Exception” or “Adjustment”

Variances (Article 52): Discretionary relief from development standards across all districts, never to permit a prohibited use, and never from procedural rules. They require a public hearing before the Planning Commission and specific findings. See § 21-52.1 – 21-52.5.
Development Standard Exceptions (Article 42): Built-in relief for common situations (e.g., nonstandard lots, official setback lines, height and coverage exceptions), often administered by the Review Authority without a variance. See § 21-42 generally.
Overlay- and topic-specific exceptions/variances:
- Airport hazards overlay: a specialized “variance permit” to the Zoning Administrator with FAA coordination. See § 21-39.9(c).
- Riparian corridor overlay: “exceptions” and “conditional exceptions” (treated like minor use permits) administered by the Zoning Administrator. See § 21-37.3(c) and § 21-37.6.
- Parking adjustments: shared/joint-use and district tools under Article 46, reviewed by the Review Authority. See § 21-46.13(c)–(d) and § 21-40.4.
- Density bonus: Board-approved bonus housing may reduce development standards without further variances or waivers. See § 21-27(l).

Variance process and findings

Applicability: All zoning districts; not for uses; only for land, building, or structure standards. See § 21-52.2(a)–(c).
Application and hearing: Filed on prescribed forms, with a fee; Planning Commission is the Review Authority; notice per § 21-57.3. See § 21-52.3 – 21-52.4.
Required findings: special circumstances depriving privileges enjoyed by similar properties; no special privilege; consistent with the intent of the Ordinance and the General Plan; no detriment to public health/safety/welfare. See § 21-52.5.
Appeals: Planning Commission actions may be appealed to the Board of Supervisors within seven days; appeals are de novo public hearings. See § 21-58.30 – 21-58.36.
Reapplication, revocation, modification: A denied variance can’t be refiled for six months unless allowed “without prejudice”; permits may be revoked or modified for cause after hearing. See § 21-60.31 – 21-60.33 and § 21-60.10 – 21-60.18.

Development Standard Exceptions (Article 42) that often avoid a variance

Lots of record: Legal nonstandard lots may be used; slight area/width modifications via lot line adjustment. See § 21-42.2.
Yard/setback clarifications and odd/through lots: Rules for through lots, corner lots, and odd-shaped parcels; Planning Director may determine yards. See § 21-42.1(d)–(g).
Official setback line: When adopted, yards are measured from the official line. See § 21-42.20 – 21-42.23.
Height and coverage exceptions: Utility towers exempt; general height may exceed limits with a major use permit; coverage relief for small R-1/R-2 lots. See § 21-42.12, § 21-42.14, § 21-42.15.
Length-to-width ratio: Subdivision relief by Review Authority, or via major use permit if strict compliance is problematic. See § 21-42.16.
Fences/walls: Height over 6 ft around tennis courts via minor use permit; front-yard fence options in some commercial/industrial districts. See § 21-42.11(d)–(e).

Other exception/permit pathways that interact with variances

Performance standards “exceptions” (noise, glare, erosion, etc.): Noncompliant uses must obtain a use permit; agricultural uses have limited exemptions. See § 21-41.3.
Parking exceptions/adjustments: Alternatives may be conditioned to avoid special privilege. See § 21-40.4.
Design-focused review: Some districts require design review or development review; those permits have their own findings and appeal paths. See § 21-56.

Overlays that commonly trigger exceptions instead of variances

Airport hazards (Article 39): Zoning Administrator may grant a special “variance permit” after FAA notice and input; obstruction marking may be required as a condition. See § 21-39.9(c), (d).
Riparian corridor (Article 37): Exceptions/conditional exceptions to allow development activity with conditions (e.g., buffers, erosion control). See § 21-37.6.
Scenic Combining (Article 34): Stricter yard/height near scenic roads; Planning Director can reduce to base-district yards if hardship or no scenic impact; thus often no need for a variance. See § 21-34.11(a).
See Lake County Overlay Districts and Lake County Historic Preservation for overlay-specific procedures.

Checklist

Confirm your parcel is in the unincorporated County (not an incorporated city).
Identify the base district and any overlays; note applicable development standards.
Check if an Article 42 exception (or overlay-specific exception) already solves the issue without a variance.
If seeking a variance, prepare evidence of special circumstances (size, shape, topography, location, surroundings) and why strict application deprives privileges enjoyed by nearby, similarly zoned parcels.
Show the request won’t grant a special privilege and won’t harm public health, safety, or welfare.
File the application on County forms with required fee; expect a Planning Commission hearing with notice per § 21-57.3.
Plan for potential appeal timelines (7 days to appeal to Board) and conditions of approval.
If denied, note the six-month wait to reapply unless “denied without prejudice.”

Risks & Ambiguities

Issue	Why it matters	What to verify
Use variances prohibited	A variance cannot legalize a prohibited use	Confirm the use is permitted/conditionally permitted in the base district. § 21-52.2(b)
Overlay rules differ	Airport/Riparian have their own exception/variance paths	Check overlay map and follow Article 37 or 39 procedures. § 21-39.9; § 21-37.6
Notice and appeals	Missed timelines can finalize decisions	Track the 7-day appeal windows and de novo hearing rules. § 21-58.30–58.36
Built-in exceptions exist	You might not need a variance	Review Article 42 tools before filing a variance. § 21-42
Parking relief path	Parking shortfalls often handled via adjustments	Use Article 46/§ 21-40.4 adjustments instead of variances.
Permit modification/revocation	Noncompliance can change or void approvals	Understand § 21-60.10–60.21 conditions and enforcement.
R-3/MP standards not located	Dimensional triggers unclear in limited source coverage	Not found in source materials. Verify with the jurisdiction.

Plain-English Summary

In unincorporated Lake County, you can ask for a variance to bend a rule like a setback or height—never to allow a prohibited land use. You must prove special circumstances and that you’re not getting a special privilege. Often you won’t need a variance at all: the code already provides exceptions for odd-shaped lots, official setback lines, small-lot coverage, parking adjustments, and certain overlay areas.

Frequently asked questions

Can I get a variance to allow a commercial use in a residential district in unincorporated Lake County?

No. Variances can’t approve new uses; they only adjust development standards for allowed uses. See § 21-52.2(b). If your use isn’t permitted, explore a use permit or rezoning instead.

What findings do I need to prove for a variance on my R-1 lot’s setback?

You must show special property circumstances (size, shape, topography, location, surroundings) that deprive you of privileges similar to nearby R-1 parcels, that no special privilege is granted, and that it’s consistent with the Ordinance/General Plan and not detrimental to public welfare. See § 21-52.5.

Is there a simpler path than a variance if my lot is oddly shaped?

Often yes. Article 42 has yard and frontage rules for through and corner lots, plus official setback line and coverage/height exceptions that may solve the issue without a variance. See § 21-42.1–42.2, 42.15, 42.20–42.23.

How are parking shortfalls handled for small commercial projects?

Try the parking “adjustment” tools first—shared/joint-use reductions approved by the Review Authority, subject to conditions. See § 21-46.13(c)–(d) and § 21-40.4.

Who hears my variance request and can I appeal?

The Planning Commission is the Review Authority for variances, with public notice per § 21-57.3. Any decision can be appealed to the Board of Supervisors within seven days; the Board holds a de novo hearing. See § 21-52.4; § 21-58.30–58.36.

What if my project is near an airport?

The airport overlay uses a different process: apply to the Zoning Administrator for a “variance permit,” including FAA notice and review; conditions like obstruction lighting may be required. See § 21-39.9(c)–(d).

I’m building near a creek. Do I need a variance?

Likely not. The riparian corridor overlay uses “exceptions” or “conditional exceptions” (like a minor use permit) with protective conditions such as vegetated buffers and erosion control. See § 21-37.6.

If my variance is denied, how soon can I reapply?

Generally you must wait six months to reapply unless the denial is “without prejudice,” which allows earlier resubmittal. See § 21-60.31–60.32.
