San Fernando — Nonconforming Uses

Last reviewed: July 2, 2026

Overview

This page explains how the City of San Fernando treats nonconforming uses, nonconforming structures, and nonconforming lots under the San Fernando Zoning Ordinance (commonly called Title 106 in the code). It summarizes what can continue, what terminates a nonconforming right, rebuilding/repair limits, amortization periods, and agency discretion — all grounded in the local code. For general orientation see the city's San Fernando zoning & planning overview.

Note: this page stays strictly within the zoning/planning code; building-code (Title 24), tenant law, and general permitting procedures are out of scope. Where the zoning code does not provide a required detail, the page explicitly says "Not found in retrieved materials" and advises "Verify with the jurisdiction."

How the San Fernando code defines nonconforming status

• A nonconforming structure is "a structure that was legally constructed and which does not conform to current code provisions/standards prescribed for the zoning district in which the structure is located." See § 106-1181.
• A nonconforming use is "a use of a structure (either conforming or nonconforming) or land that was legally established and maintained prior to the adoption of this title, and which does not conform to current code provisions governing allowable land uses for the zoning district in which the use is located." See § 106-1181.

Core rules that control continuance and termination

• Continuation is generally permitted but is not encouraged; enlargement, extension, or structural alteration that increases nonconformity is prohibited except as expressly allowed. See § 106-1025(1) and § 106-1027(1).
• A nonconforming use or structure discontinued or abandoned for six consecutive calendar months loses its nonconforming status and must thereafter conform to the zone. See § 106-1025(5) and § 106-1026(5).
• If a structure qualifying as nonconforming is destroyed more than 50 percent of its replacement cost, it cannot be reconstructed except in conformance with current code. See § 106-1027(2) and § 106-1026(6).
• Some amortization/termination schedules apply to types of nonconforming uses (ranges from 1 year to 50 years depending on land/use/structure type). See the allowable life table in § 106-1033.

Where the code lets officials exercise discretion

• The director may permit limited replacements or footprint‑identical reconstruction if the proposal restores safety, is substantially similar, and is the only feasible option (see § 106-188(5) and § 106-1027). Approval authority and referral rules for modifications are in § 106-953—106-955.
• The Planning Commission may allow a change from one nonconforming use to another only if the proposed use is no more detrimental; the commission may add conditions. See § 106-1025(3) and § 106-1026(3).

District-by-district practical breakdown (nonconforming rules and where they matter)

Note: the San Fernando code uses base zones (residential, commercial, industrial) and specific plan zones. The ordinance contains many zone names; below are districts that appear in the nonconforming sections and related development-standard sections of the code. For full permitted-use tables and dimensional values consult San Fernando Zoning and San Fernando Development Standards. If a district item below is not explicitly detailed in the retrieved materials, that line states "Not found in retrieved materials."

R-1 (single-family residential)

• Purpose: conventional single-family regulation (referenced throughout the code). See the R-related general provisions and the urban two‑unit special rules.
• Typical permitted uses: single‑family dwellings, accessory uses (code lists elsewhere). Not found in retrieved materials: a full permitted-use list for R-1 in the snippet retrieved. Verify with the jurisdiction.
• Nonconforming specifics: the code allows development of nonconforming land for a dwelling and accessory buildings on any lot lawfully of record as of the ordinance effective date, notwithstanding lot width/depth limits; yard/open-space requirements still apply unless a variance is granted. See § 106-1024.
• Key dimensional standards: Not fully listed in the nonconforming excerpts. See San Fernando Development Standards for setbacks and lot coverage; the Director may apply average setback rules for shallow lots per § 106‑188(c).

C-1 and C-2 (Commercial zones)

• Purpose: limited and general commercial activities serving neighborhood and citywide needs. Not found in retrieved materials: the full purpose statement and permitted‑use tables in the snippets provided. Verify with the jurisdiction.
• Typical permitted uses: commercial retail, services, and some dwellings in mixed situations (see Mixed Use Overlay). Not found in retrieved materials: full lists.
• Nonconforming specifics: an existing nonconforming dwelling in C-1 or C-2 that is destroyed more than 50 percent of replacement cost may, in limited circumstances, be rebuilt on the same footprint if the lot is ≤ 5,000 sq ft and fronts on a residential street (not a commercial thoroughfare). See § 106-1027(6).
• Key dimensional standards: Not found in retrieved materials for full commercial dimensional table here; consult San Fernando Development Standards.

M-1 (Limited Industrial) and M-2 (Light Industrial)

• Purpose: industrial and employment uses; the code places stricter controls on outdoor storage, walls, and utilities in these zones. See development standards in § 106-104.
• Typical permitted uses: industrial, manufacturing, warehouses; wireless facilities allowed with restrictions. See § 106-776(b) for wireless location rules.
• Nonconforming specifics: general nonconforming structure/use rules apply (no enlargement; >50% destruction ends nonconforming reconstruction rights). See § 106-1027.

SP-5 / Workplace Flex District (San Fernando Corridors Specific Plan)

• Purpose: SP zones support tailored development under an adopted specific plan. The Workplace Flex District within SP-5 is explicitly listed for allowable wireless facilities subject to conditional use permit. See § 106-776(b)(1) and the SP intent § 106-131.
• Nonconforming specifics: general nonconforming provisions apply; wireless facilities established before the ordinance are treated as legal nonconforming but subject to restrictions on expansion per § 106-772.

Checklist — what an applicant must satisfy (nonconforming topic)

• Demonstrate the use or structure was lawfully established prior to the ordinance amendment (evidence of earlier permits/records). See § 106-1181.
• Confirm the nonconforming use has not been abandoned for 6 months; if it has, plan must conform to current zone standards. See § 106-1025(5).
• If proposing reconstruction after damage, calculate percent damage against assessed replacement cost to determine if > 50%; if >50% reconstruction must be conforming. See § 106-1027(2) and § 106-1028.
• If seeking to change to another nonconforming use, prepare findings showing the new use is no more detrimental; planning commission review likely required. See § 106-1025(3).
• If seeking any dimensional relief related to reconstruction, check whether Director-level modifications apply (e.g., average setback rules) and include justification under § 106-188. See § 106-188(c).
• When work would affect parking, confirm off-street parking will not be infringed (public uses additions rule) and consult San Fernando Parking. See § 106-1030(2).

Risks & Ambiguities

Plain-English summary

If your property in San Fernando predates the current zoning rules and now doesn't match them, you can usually keep operating, but you cannot enlarge the nonconforming part, and long interruptions (6 months) or heavy damage (>50% of replacement cost) will strip away the special rights — with a few narrow exceptions (for example small dwellings in C‑1/C‑2). The Planning Commission and Director have limited discretion to allow changes, so verify facts and paperwork before you plan work. See the controlling local code sections cited below.

Information Gaps

• Complete, per‑zone permitted‑use lists and full dimensional tables for R-1, C-1, C-2, M-1, M-2, and SP zones (the retrieved excerpts reference these zones but did not include full use tables or the numeric setback/height/coverage tables). Verify with the jurisdiction or consult San Fernando Zoning and San Fernando Development Standards.
• Any local administrative forms, fees, or submittal checklists required for a nonconforming‑use determination or Director modification are not in the retrieved materials. Verify with the Community Development Department.
• The Code references interactions with building/fire codes for change of utilization; the specific trigger points for Title 24 compliance vs. zoning compliance (for conversion or reconstruction) are Not found in retrieved materials — consult building department and see California Building Standards Code.
