Patterson — Variances and Exceptions

Last reviewed: July 2, 2026

Overview

Variances and exceptions in Patterson are the city's tools for limited flexibility when strict application of the zoning rules would deprive a property of rights enjoyed by similarly zoned parcels. The primary variance procedure and findings are in § 18.18.030; smaller discretionary relaxations are handled through minor adjustments (Table 18.16.110‑1) and other adjustment/waiver provisions. The planning commission is the typical decision body for variances; the planning director handles many minor adjustments and design-level exceptions.

How Patterson's code organizes relief from standards

• Variance: formal discretionary relief from development standards where unique site circumstances exist; governed by § 18.18.030 and requires specific findings by the planning commission.
• Minor adjustment: director-level administrative relief limited to specific standards listed in Table 18.16.110‑1 (e.g., small setback reductions, limited height increases); findings and limits are in § 18.16.110 and implemented by the planning director.
• Adjustment / Waiver / Fee reduction: for certain development-fee or inclusionary requirements, appeal/waiver to the city council under § 18.86.120 (density/fee/in-lieu and nexus disputes).
• Project-specific exceptions (sign area exceptions, parking hardship exceptions, etc.) are handled in the respective chapters (for example, sign exceptions in § 18.82.090; parking reductions and hardship exceptions in § 18.76.090).

See the city's baseline development standards in the Patterson Development Standards before pursuing relief; small procedural and design items may be cleared through Patterson Design Review or a minor adjustment rather than a variance. Also check parking, overlay districts, and ADUs rules early in planning.

Core statute and required findings

• Purpose statement and applicability: see § 18.18.030(A–B) — variance exists to address exceptional circumstances (size, shape, topography, location) but cannot be used to allow a use otherwise prohibited or to increase residential density (except as state law allows).
• Required findings (all must be made by the planning commission): § 18.18.030(D)(1–4) — (1) exceptional circumstances unique to the property, (2) no adverse effect on health/safety/welfare with conditions, (3) strict code application deprives the property of privileges enjoyed by others in the same district, (4) the variance will not be a special privilege.
• Application contents and process: § 18.18.030(C) — plot plans, elevations, landscaping, studies as needed; applicant bears the burden of proof; public hearing required per § 18.14.050.
• Time limits, revocation, and running with the land: see § 18.18.030(F–I) (variance revokes if not exercised within one year unless conditions state otherwise; variance generally runs with the land; revocation rules cross-reference § 18.14.110).

District-by-district breakdown: where variances / exceptions are commonly used

Note: Patterson uses multiple base zoning districts (abbreviations are the city's; the development‑standards tables list the exact dimensional standards). Below are the actual district names and the code references for their baseline standards — use these as the baseline when making a variance or minor adjustment request. For all districts, confirm precise parcel zoning on the official map (Verify with the jurisdiction).

ER (Estate Residential)

Purpose & typical uses: low‑density single‑family lots and estate homes. See Table 18.38.040‑1 for density and setbacks.
Key development standards (high‑level): front yard 20 ft, side 5 ft, rear 20 ft, maximum lot coverage 40%, primary height 2 stories/32'. Use cases for variances: small setback relief, lot coverage relief on constrained lots; adjustors: minor adjustments are limited and often smaller than variance relief.

LR‑n / LR‑w (Low‑density Residential — north/west)

Purpose & uses: conventional single‑family neighborhoods. Table 18.38.040‑1 lists minimum lot sizes (e.g., 6,000 sf typical), setbacks front 20 ft / side 5 ft / rear 20 ft, coverage up to 70% for LR‑n/w. Common variance requests: reduced front or side setbacks on irregular lots; accessory structure relief.

DR (Downtown Residential)

Purpose & uses: higher-density downtown housing; allowed taller primary structures (up to 3 stories/45') and larger lot coverage (up to 80%). Variances and minor adjustments (Table 18.16.110‑1) are explicitly limited for some DR items (e.g., certain projection allowances and small setback tweaks). Verify whether minor-adjustment relief (director) is available before a variance.

MR / HR (Medium/High Residential)

Purpose & uses: multi‑family and denser housing. Standards: MR typical max density ~12 units/acre, HR up to 20 units/acre; setbacks similar pattern but larger separation requirements for HR (see Table 18.38.040‑1). Variances here often involve lot‑dimension reductions, parking adjustments, or height exceptions for architectural features (height increases for towers/steeples are considered via minor adjustment or variance depending on magnitude).

Commercial districts — NC, HSC, DC, GC, MPO

Purpose & uses: neighborhood commercial, highway service/commercial, downtown core, general commercial, medical/professional office. Development standards are in Table 18.42.040‑2 (front yards, side & rear yards, lot area minima, heights). Common variance/exception requests: sign‑area exceptions (see § 18.82.090), parking reductions or shared‑parking agreements, minor setback or parking dimension adjustments. For parking‑related relief see Patterson Parking.

Industrial districts — LI, HI, IBP

Purpose & uses: light industrial, heavy industrial, West Patterson Industrial Business Park. Industrial standards and special buffers are in Chapter 18.46; heavy industrial areas are where the city may permissibly site more intensive uses (e.g., the emergency shelter overlay is in an HI area). Variances here commonly address setbacks, landscaping/screening, or operational buffers to residential zones.

Overlay districts — PD (Planned Development), HP (Historic Preservation), and others

Purpose & effect: overlays supplement base standards and can change the test applied for exceptions. The PD overlay expressly allows the modification of base standards as part of a PD entitlement (see § 18.54.020) — but note interim exceptions and that PD entitlement itself requires a separate application. The HP overlay imposes additional review and can restrict demolition/alteration; variance/exception requests in historic areas often have an additional historic‑review requirement. Consult Patterson Overlay Districts for boundaries.

What types of standards can be adjusted administratively vs. via a variance?

Use Table 18.16.110‑1 (Standards Subject to Minor Adjustment) as the starting point: administrative limits include small setback reductions (no closer than average of developed lots on the block face, and limited to 2 ft or 20% whichever is less, with an absolute cap), limited fence height increases (2 ft), modest lot coverage increases (10%), limited height increases (20%), and minor parking reductions (up to 15% administratively). Larger or nonlisted deviations require a variance or conditional use review.

Table — Quick decision guide

Practical guidance for applicants (synthesized)

• Start with Patterson Development Standards to see the base rule you're seeking relief from and check whether a minor adjustment route exists — it's faster and director‑level.
• If the requested change is not in Table 18.16.110‑1 or exceeds those numeric caps, prepare to apply for a variance and assemble robust evidence for the four findings in § 18.18.030(D) (site maps, photos, topographic constraints, comparison to adjoining lots).
• For parking or fee disputes, consider the alternate processes: parking reductions in § 18.76.090 and fee/inclusionary appeals under § 18.86.120 (appeal to city council with substantial evidence). Link early with parking staff.
• If your site lies in an overlay (e.g., PD or HP), overlay rules may supersede or add findings — check Patterson Overlay Districts and consult planning staff early.

Checklist

• Confirm zoning and base standards for parcel (district table: Table 18.38.040‑1 or district‑specific table).
• Determine whether requested relief fits minor adjustment (Table 18.16.110‑1) or requires a variance.
• Prepare application materials (plot plans, elevations, landscaping, technical reports) per § 18.18.030(C) and pay fee.
• Demonstrate the four variance findings (if variance): unique circumstances, no adverse effect, deprivation of privileges compared to neighbors, and no special privilege (§ 18.18.030(D)).
• For parking or fee relief, prepare a parking analysis or nexus evidence (see § 18.76.090 and § 18.86.120).
• Confirm whether historic overlay review or design review is required (see Patterson Design Review and HP overlay).

Risks & Ambiguities

Plain-English Summary

If your Patterson lot is physically constrained, you can ask the city for relief — small, routine tweaks go to the planning director as a minor adjustment; bigger changes that can't fit those limits need a variance from the planning commission and require you to show the site is uniquely constrained and that the change won't harm neighbors. Always check overlay rules, parking standards, and whether state ADU/density law changes what local relief is allowed.
