Elk Grove — Nonconforming Uses

Last reviewed: July 3, 2026

Overview

This page explains how the City of Elk Grove treats nonconforming uses, structures, and parcels — uses or parcels lawful under an earlier ordinance but that no longer meet Title 23 (Zoning) rules. The controlling rules are in EGMC Chapter 23.84 (nonconforming uses) and the City’s allowed‑uses and development‑standards tables (Division III). Read this page together with the city’s zoning tables and the specific district standards referenced below. § 23.84.010 establishes the purpose and intent.

What Title 23 actually says (core rules)

• Continued use but no expansion. A preexisting lawful nonconforming use of land may be continued, transferred, or sold, but it cannot be enlarged, intensified, or extended to occupy more area than it did when it became nonconforming. § 23.84.020(A)

• Nonconforming structures — repair and limited modification. A nonconforming structure may be maintained and repaired; additions or reconstruction are permitted only if the proposed change conforms to Title 23 standards or is approved through the City’s processes (including minor design review for some appearance/safety improvements). § 23.84.020(B)

• Loss of status by discontinuance. If a nonconforming use (of land or of a conforming structure) is discontinued for one continuous year or more, legal nonconforming rights terminate; the site must thereafter conform to the current zoning rules. § 23.84.040(A)(1–3)

• Loss (destruction) and rebuilding. If a nonconforming structure is involuntarily damaged/destroyed it may be repaired or rebuilt only if restoration begins within one year and the replacement meets the same footprint, height, and number of dwelling units, and current building/fire codes; special rules apply for industrial uses in agricultural or residential zones (CUP required if repair cost > 50% of assessed value). § 23.84.040(B)(1–2)

• Nonconforming parcels. A parcel that fails current area/width standards is a legal building site only if it meets one of the enumerated criteria (e.g., created by recorded subdivision or deed before the zoning amendment) and cannot be subdivided so as to increase the nonconformity. § 23.84.050(A–B)

• Uses made nonconforming by missing permits / CUPs. A use that previously operated without a now‑required CUP remains conforming only to the extent of its prior operation (e.g., same site area, hours); a use that had a CUP but is no longer allowed in that location may continue only under the original CUP terms. § 23.84.060(A–B)

• Extensions / temporary legal status. Property owners may apply for a time-limited extension of legal nonconforming status; applications are reviewed by the Community Development Director and the Commission, the max extension cannot exceed 24 months, and findings must show the prior legal establishment and that continuation will not be detrimental to public welfare. § 23.84.070(A–D,E)

• Recreational vehicles, trailers and vessels parked in a front setback before August 11, 2006, are grandfathered but lose nonconforming status under the same rules as other nonconformities (and the City may require evidence to establish status). § 23.84.031

District‑by‑district (representative) — how nonconforming rules interact with actual Elk Grove zones

Note: the city’s allowed uses are shown in Table 23.27‑1 (Allowed Uses and Required Entitlements) and dimensional rules are in Table 23.29‑1 (Development Standards for Base Zoning Districts). Refer to those tables for parcel‑specific determinations. § 23.27.020 and § 23.29.020.

AG‑80 (Agricultural — 80‑acre)

• Purpose: preserve agricultural operations and very low density development consistent with Title 23 purposes. § 23.02.010
• Typical permitted uses: agricultural production, accessory farm uses; allowed‑use table shows agricultural uses permitted in AG‑80 (see Table 23.27‑1). § 23.27.020
• Nonconforming interaction: industrial or nonfarm uses that become nonconforming are still governed by Chapter 23.84 — e.g., rebuilding after destruction or enlargement rules apply; industrial rebuilds in an agricultural zone may trigger a CUP if cost >50% of assessed value. § 23.84.040(B)(2)
• Where it applies: large, outlying parcels shown on the zoning map as AG‑80; check the allowed uses table for whether a use was originally permitted. § 23.27.020

AG‑20 (Agricultural — 20‑acre)

• Purpose & uses: similar to AG‑80 but allow smaller agricultural parcels; see Table 23.27‑1 for permitted accessory residential or employee housing uses. § 23.27.020
• Key standard to check: nonconforming parcels may be considered legal building sites only when they meet EGMC § 23.84.050 criteria (recorded deed, approved subdivision, variance/lot-line adjustment, or limited gov’t acquisition). § 23.84.050

AR (Agricultural Residential — AR‑1 through AR‑10)

• Purpose: allow low‑density residential in agricultural transition areas while protecting farm viability. § 23.02.010 and Table 23.27‑1 show AR allowable residential uses.
• Typical permitted uses: single‑family dwellings, accessory dwellings (see ADU policy), limited home occupations. § 23.27.020
• Dimensional standards: see Table 23.29‑1 for minimum lot area and densities by AR district; use that table to determine whether a parcel is legally nonconforming. § 23.29.020
• ADUs: state ADU law may limit how the City treats nonconforming zoning conditions for ADU approvals; consult the Elk Grove ADU page and state rules. Elk Grove ADUs and see state guidance.

RD‑series (Residential districts — example RD‑3, RD‑5, RD‑10)

• Purpose: progressively higher residential densities and different lot/yard standards; see Table 23.29‑1. § 23.29.020
• Typical permitted uses: single‑family, two‑unit, multiple units depending on RD band; Table 23.27‑1 shows entitlements by RD band. § 23.27.020
• Key dimensional standards (representative, from the code tables):
  • RD‑5 typical minimum setbacks: Front, living area: 15 ft; Side interior: 5 ft; Rear: 15 ft. See Table 23.29‑1 / RD development table. § 23.29.020
  • RD‑10 and others have specific front/porch/garage setbacks and lot depths listed in the same table — consult Table 23.29‑1 for exact numeric requirements for a parcel. § 23.29.020
• Nonconforming interplay: accessory structures in RD zones that are nonconforming may be repaired; accessory structures with footprints >800 ft2 may require minor design review before building permit. See accessory structures rules. § 23.46.030(B)

LC (Local Commercial)

• Purpose / uses: neighborhood commercial services; see Table 23.27‑1 for permitted commercial uses in LC. § 23.27.020
• Dimensional/parking: follow general development and parking chapters; parking modifications to an existing nonconforming use may require zoning clearance (see parking rules). Elk Grove Parking § 23.58.030
• Nonconforming signs: signs lawfully established before adoption are grandfathered but may not be altered in a way that increases nonconformity; see § 23.62.160.

Overlay — East Elk Grove (EEG) (example of overlay rules)

• Purpose: allow standards consistent with historic patterns that may deviate from the base zone. § 23.42.100(A)
• Development standards: Table 23.42‑4 spells out lot area, frontage, depth, and setbacks for RD‑3 through RD‑10 in the EEG; these override or supplement the base zone standards where applicable. § 23.42.100(C)
• Nonconforming items created by overlay changes are still handled under Chapter 23.84 (loss, rebuild, extension procedures). § 23.84.010

Quick reference table (decision‑relevant nonconforming rules)

Checklist — what an applicant must show/do for nonconforming uses (practical)

• Establish that the use/structure was lawfully established prior to the zoning change (provide deeds, permits, business records, dated photos, DMV registration for vehicles) — see § 23.84.070(A)(3).
• For continued operation: ensure the use is not enlarged or occupying a larger area than before (per § 23.84.020(A)).
• If rebuilding after damage: begin restoration within one year and comply with current building/fire codes; if repair costs exceed 50% of assessed value for industrial uses in ag/res zones, apply for CUP first (§ 23.84.040(B)).
• If nonconforming status is at risk (e.g., a year of inactivity), submit an application to extend legal nonconforming status before the one‑year expiration (see § 23.84.070(A)(2) for timing and § 23.84.070(F) on staying loss).
• If you propose building changes that affect development standards (setbacks, lot coverage), check the applicable base zoning table (Table 23.29‑1) and overlay tables (e.g., Table 23.42‑4 for EEG) and submit required design review/clearances. § 23.29.020 and § 23.42.100.
• If sign, parking or accessory structure questions arise, follow the specific chapters: signs (§ 23.62), parking (§ 23.58), accessory structures (§ 23.46) and confirm whether changes increase nonconformity.

Risks & Ambiguities

Plain‑English summary

If a use or building in Elk Grove was legal under the old rules, you can usually keep it, but you cannot make it bigger or leave it unused for a year — or it loses the grandfathering. Chapter 23.84 explains how long you have, when you must get a conditional permit to rebuild, and what documentation you must provide. § 23.84.020–070.
