Blythe — Nonconforming Uses

Last reviewed: July 1, 2026

Overview

Blythe regulates existing uses, structures, signs, and lots that no longer meet current zoning standards under Title 17, Chapter 17.34 of the Blythe Zoning Ordinance. The rules let lawful nonconformities continue but tightly limit expansion, set loss-of-rights timeframes, and trigger upgrades when work crosses certain value thresholds. See the broader Blythe Zoning framework for how districts, uses, and standards align with the General Plan, and consult Blythe Development Standards for the dimensional baselines that nonconformities are measured against.

How Blythe treats nonconforming lots, uses, structures, signs, and site features

• Definitions. A nonconforming lot is a legal lot that doesn’t meet current dimensional rules; a nonconforming structure is a building/structure that doesn’t meet current use or development standards; a nonconforming use is a use existing on October 12, 1982 that no longer conforms. All must be otherwise lawful. The intent is to allow continuation, but not enlargement, expansion, or extension beyond what Chapter 17.34 allows (§ 17.34.010; § 17.34.020) .
• Continuation vs. loss of rights. A nonconforming use of land loses its status if it ceases for more than 30 days; a nonconforming use in a structure loses its status if discontinued or abandoned for one year (§ 17.34.030.C; § 17.34.040.D) .
• No enlargement. A building devoted to a nonconforming use may not be enlarged, extended, reconstructed, moved, or structurally altered, except to change to a conforming use. Limited extension within portions of a building “manifestly arranged or designed” for the nonconforming use as of October 12, 1982 is allowed; no extension onto land outside the building (§ 17.34.040.A–B) .
• Change to conforming = no going back. Once a nonconforming use is superseded by a permitted use, you cannot resume the nonconforming use (§ 17.34.040.C) .
• Repairs and maintenance. Ordinary repairs that do not increase the structure’s cubic content are allowed. If a nonconforming structure (or portion containing a nonconforming use) becomes unsafe/unlawful due to lack of maintenance and is so declared, it may only be restored in full conformity. Strengthening/restoring to a safe condition is allowed upon order by the safety official; at that time a conditional use permit may be granted to allow a use to continue that would otherwise become unlawful under other provisions (§ 17.34.050) .
• Damage and rebuilding. You may reconstruct a damaged nonconforming building if the cost of reconstruction does not exceed the structure’s fair market value at the time of damage, you obtain a building permit within 2 years, and complete within 1 year of permit issuance (§ 17.34.041) .
• Site upgrades (“nonconforming areas”). Where existing uses lack current requirements for landscaping, trash enclosure pads (commercial/industrial), screening and street improvements (residential), or parking, they may continue without these improvements until the use is intensified or the cost of repairs/alterations reaches 50% of the structure’s assessed valuation (cumulative over 5 years). Partial permits do not avoid this threshold (§ 17.34.055). Parking upgrades, when triggered, must meet current Blythe Parking standards (§ 17.34.055) .
• Signs. You cannot extend/enlarge a nonconforming use by adding more off-premises-visible signs (§ 17.34.060). For current sign rules, see Blythe Signage (§ 17.34.060) .
• Nonconforming lots. Legal substandard lots may be occupied by uses permitted in the zone; residential lots may have the number of units allowed by density, and if smaller than the minimum lot size for one unit, one dwelling may still be allowed if standards are met or acceptably modified. Minor variances may be used where strict application would deprive privileges (§ 17.10.020.A–C; Chapter 17.70) . Special rules: in C‑M‑O the planning director may vary side setbacks for a nonconforming lot to zero, subject to specific conditions (§ 17.10.020.D); in I‑G a conditional use permit is required to occupy a nonconforming lot (§ 17.10.020.E) .
• District baselines matter. Development standards such as minimum lot area/width/depth (§ 17.10.010), residential lot coverage (§ 17.10.015), and building height (§ 17.10.040) define what is conforming in each district—and therefore when a situation is nonconforming . Landscaping/screening upgrades, when triggered, must meet current Blythe Landscaping and Screening standards (§ 17.34.055) .
• Adult businesses—amortization example. Sexually oriented businesses that became nonconforming on July 1, 1998 were allowed to continue for up to one year unless earlier terminated; they may not be enlarged or extended, and later-established nearby operators become the nonconforming use (§ 17.49.120.G–H, as excerpted) .
• Map and where rules apply. The current zoning map is on file with the City Clerk; confirm your district before applying nonconforming rules (Editor’s note to Title 17) . See Blythe Land Use for plan consistency.

Checklist

• Identify the nonconformity type: lot, use, structure, sign, or site features (landscaping/screening/parking/street improvements) (§ 17.34.010–.020; § 17.34.055) .
• Establish the lawful status and the key date: existed and lawful as of October 12, 1982 for uses/structures (§ 17.34.020) .
• Verify your zoning district on the city’s official zoning map; pull applicable baselines in § 17.10 for lot/height/coverage (Editor’s note; § 17.10.010–.040) .
• If a nonconforming use of land stopped, confirm whether the gap exceeded 30 days; if a nonconforming use in a structure stopped, confirm if ≥ 1 year (§ 17.34.030.C; § 17.34.040.D) .
• Scope the work: no enlargement/extension/move/structural alteration of a nonconforming use except to a conforming use; limited in‑building extension only if arranged for that use on 10/12/1982 (§ 17.34.040.A–B) .
• For repairs/maintenance, ensure no increase in cubic content; if declared unsafe due to neglect, plan a conforming rebuild (§ 17.34.050) .
• For disaster damage, confirm fair market value and timing: permit within 2 years, complete within 1 year (§ 17.34.041) .
• Add up all repair/alteration costs over 5 years against assessed value to see if landscaping/screening/parking/street improvements are triggered (§ 17.34.055). Coordinate with Blythe Landscaping and Screening, Blythe Parking .
• For nonconforming lots, consider minor variances (§ 17.70) and any zone rules (e.g., C‑M‑O side setback flexibility; I‑G CUP need) (§ 17.10.020.D–E; Ch. 17.70). See Blythe Variances and Exceptions .
• Signs: do not add off‑premises‑visible signs that would expand the nonconforming use (§ 17.34.060). See Blythe Signage .
• If located in any special or Blythe Overlay Districts, or if Blythe Design Review applies, verify additional requirements. Not found in retrieved materials.

Plain-English Summary

Blythe lets older, lawful uses and buildings keep operating even if today’s zoning would not allow them. But if you stop using the land for more than 30 days (or stop a building‑based nonconforming use for a year), you lose that status. You can keep up maintenance that doesn’t enlarge the building, and you can rebuild after a disaster if costs don’t exceed fair market value and you stay within strict timelines. Big repairs or intensifying activity may force you to add modern landscaping, screening, parking, or street improvements. If you’re on a substandard lot, you may still build, and minor variances or a CUP can sometimes help—especially in the C‑M‑O and I‑G zones. When in doubt, confirm your district and talk to Planning early.
