Fowler — Nonconforming Uses

Last reviewed: July 2, 2026

Overview

This page explains how the Fowler zoning ordinance treats nonconforming uses, nonconforming structures, and nonconforming lots: what may continue, what must end, limits on repairs/expansions, and special rules for different districts. The rules are coded in Article 29 of the Fowler Zoning Code (the nonconforming-uses article) and are summarized here with plain‑English interpretation and exact code citations for every rule. See the city's general rules for development standards, parking, design review, overlay districts, ADUs, California Building Standards Code (Title 24), and variances and exceptions where the nonconforming property interacts with those topics.

Key high-level rules (Article 29):

• A use or structure lawfully existing before the ordinance that no longer complies is a nonconforming use/structure and is generally allowed to continue under limits (purpose and continuation rules) — § 9-5.29.01 and § 9-5.29.02.
• Destruction, abandonment, expansion, alteration and time limits are specifically regulated (see the district breakdown and standards table below) — e.g., destruction/repair thresholds are in § 9-5.29.06 and § 9-5.29.07.

How Article 29 applies district-by-district

Below are Fowler’s principal districts where the ordinance either states district purpose/uses or calls out nonconforming exceptions. For each district I summarize the district purpose, typical permitted uses (as the ordinance lists them), then the specific nonconforming-use implications drawn from Article 29 and any district-specific language.

Note: the ordinance uses "R zones" as a family of residential districts; where the code names a specific district (for example RM-3, RCO, UR, M-1/M-2 or form-based areas) I name it exactly and cite the code.

R zones (general residential districts)

• Purpose / where it applies: Residential districts intended for one‑family and related residential uses; individual district standards appear across Article 5 (see the applicable R district code for exact setbacks/coverage). See development standards for those dimensional tables.
• Typical permitted uses: one‑family dwellings, accessory structures, home occupations (subject to Article 21), etc. (see specific R district sections in Article 5).
• Nonconforming rules that matter in R zones:
  • Any nonconforming structure in an R zone that is not a residential dwelling and was designed/intended for a use not permitted in the zone must be removed or altered to conform; timing considers the building’s normal life as determined by the Director (but never less than 40 years from original construction). A removal/alteration order cannot require change sooner than three (3) years from the order date; notice and recording requirements apply (§ 9-5.29.08.D, procedural notice rules in § 9-5.29.08.D.4–5).
  • Home occupations that are nonconforming must be discontinued within one (1) year (§ 9-5.29.08.E).
  • Routine maintenance and repairs are allowed (§ 9-5.29.02.D).

RM-3 (multi-family/residential‑mixed)

• Purpose / where it applies: higher density residential and mixed residential uses; some multi‑family specific dimensional standards referenced in RM-3 text.
• Typical permitted uses: multi‑family dwellings, accessory uses, and residential over commercial in specified areas (see RM-3 section).
• Nonconforming rules:
  • General Article 29 continuation rules apply: nonconforming structures that fail coverage/yard/height standards may be maintained (§ 9-5.29.02.B) and routine maintenance is allowed (§ 9-5.29.02.D).
  • Districts commonly include the same 50% remodeling allowance referenced for multiple districts (see the Permitted Uses: Administrative Approval language cited below).

C and M zones (Commercial and Industrial)

• Purpose / where it applies: Commercial (C) and Industrial (M) districts for retail, services, manufacturing, distribution, and related uses; see the particular C or M article for exact uses and standards.
• Typical permitted uses: the code lists many uses by district (restaurants, retail, light manufacturing, etc.). See the district use lists in Articles 10, 13, 14, 15 and 17.
• Nonconforming rules that matter here:
  • A nonconforming structure in a C or M zone may be continued even where other zones would force removal — the code expressly permits continuation in those zone categories (§ 9-5.29.08.C).
  • Across multiple commercial/industrial districts the ordinance authorizes expansion or remodeling of an existing nonconforming use of a structure or land up to 50% of the value (subject to Article 24 administrative processes) — see the Permitted Uses: Administrative Approval subsections for districts like downtown/commercial, industrial and mixed-use areas (§ 9-5.1004, 9-5.1404, 9-5.1504, 9-5.1706, 9-5.504, 9-5.704) which incorporate the 50% rule.

RCO — Resource Conservation / Public Use / Open Space (RCO)

• Purpose / where it applies: parks, open space, public facilities; see Article 5 RCO section.
• Typical permitted uses: parks, flood control facilities, public uses and schools (§ 9-5.503).
• Nonconforming rules:
  • The RCO district language also repeats the 50% remodeling rule for expansion or re‑establishment of nonconforming uses in its permitted uses (§ 9-5.504). Routine maintenance allowed (§ 9-5.29.02.D) and the general abandonment/continuation rules apply.

UR — Urban Reserve, PUD overlay, Form‑Based Areas, and other overlays

• Purpose / where it applies: UR and PUD overlay regulations and Form‑Based Code area rules add procedural or design controls; a PUD overlay applies the underlying zone plus special conditions (§ 9-5.28.10) and Form‑Based areas have their own permitted uses lists.
• Typical permitted uses: vary; PUD overlays apply additional design/approval standards and do not generally change Article 29 nonconforming rules unless specifically stated.
• Nonconforming rules:
  • Overlay application does not erase Article 29 protections; PUDs remain subject to the base district rules and Article 29 (§ 9-5.28.10). Confirm overlay-specific language for any special treatment of nonconforming status in the overlay text.

Checklist

• Establish that the use/structure was lawfully established prior to the ordinance or amendment (evidence: prior permits, deeds, historical records). Reference: § 9-5.29.01.
• Determine whether the nonconformity is a use, a structure, or a nonconforming lot (Article 29 distinguishes these categories). Reference: § 9-5.29.01–§ 9-5.29.02.
• If proposing repair after damage, get an estimate comparing pre‑damage reasonable value to repair cost to apply the 75% restoration threshold in § 9-5.29.06.
• If proposing alteration/expansion, calculate whether the work exceeds 50% of assessed/value thresholds where the code allows modest expansion only (district-specific admin permissions). See district permitted‑uses (e.g., § 9-5.1004, § 9-5.1404).
• If a nonconforming use is to be changed to another nonconforming use, prepare justification showing similarity and non‑detrimental impacts for Director review (§ 9-5.29.03.B).
• Check abandonment/vacancy history; continuous vacancy >1 year (non‑dwelling) or discontinuance >90 days (site) can extinguish nonconforming rights (§ 9-5.29.03.D, § 9-5.29.09).
• If located in an R zone and nonconforming structure is not a dwelling, anticipate removal/alteration timing and Director orders including minimum notice and recording requirements (§ 9-5.29.08.D).
• Confirm whether the property lies in overlays (e.g., PUD, Form‑Based), and confirm overlay does not impose different nonconforming rules; check overlay districts.

Risks & Ambiguities

Plain‑English Summary

If your building or use in Fowler was legal before the current zoning rules but doesn't fit now, Article 29 lets you keep it in most cases — but there are firm limits: long vacancies, major destruction (over 75%), or certain expansions can end that protection, and residential zones are stricter than commercial/industrial ones. Check the exact thresholds in Article 29, especially § 9-5.29.02 through § 9-5.29.09, and confirm district‑specific allowances (many districts allow up to a 50% value‑limited remodel) before you spend on repairs or changes.

Information Gaps / Items not found in the retrieved materials

• The code text in the files does not include a single consolidated table listing every R‑zone numeric setback/coverage that might be needed to compute "nonconforming solely by reason of yard or height" — for specific front/side/rear setbacks and coverage percentages consult the district development standards tables in Article 21/Article 5 or the city’s development‑standards summary. Not found in retrieved materials.
• The ordinance references Director discretion for "normal life" of a building and how it is determined but does not include a formula for that determination. Verify with the jurisdiction (Planning Director). § 9-5.29.08.D.1–2 indicates the Director sets it; the minimum is 40 years.
