Maywood — Nonconforming Uses

Last reviewed: July 6, 2026

Overview

Maywood’s zoning ordinance sets a detailed, amortization-based framework for how existing uses and structures that don’t meet current rules can continue, change, or must end. The core rules live in the Nonconforming Uses and Structures provisions of the Maywood Zoning Ordinance, § 5080.10–5080.90 . Citywide revocation procedures and district standards also matter, especially in the R-3 residential district and the C/CM commercial districts where special carve‑outs apply .

Stopping a nonconforming use for six or more consecutive months permanently ends the right to operate it in Maywood (termination by discontinuance, § 5080.80.A) .

How Maywood treats nonconforming uses and structures

• Scope and continuation

  • Rules apply only to uses/structures that were lawful when established and not otherwise illegal at the time the current ordinance or an amendment took effect (§ 5080.10) .
  • A nonconforming use may continue through its amortization period, but you cannot alter, add to, or enlarge the area/volume devoted to it except as expressly allowed in § 5080 (§ 5080.20) .

• Ordinary repairs and allowed alterations

  • Ordinary repairs and maintenance to keep a nonconforming structure safe are allowed (§ 5080.30) .
  • Limited expansions/alterations may be allowed:
    • Alterations required by later ordinances must be permitted (§ 5080.40.A) .
    • If the only nonconformance is insufficient off-street parking/loading, expansions may proceed if all parking and loading are brought up to current standards (§ 5080.40.B) . See Maywood Parking.
    • Additions to a structure nonconforming for yards/height/parking-lane dimensions may be made if the new addition meets current standards (§ 5080.40.C) . See Maywood Development Standards.

• Damage/reconstruction

  • In the R-3 district, a legally established nonconforming structure that is damaged or destroyed may be rebuilt to its pre-damage condition if work starts within 1 year and proceeds diligently (§ 5080.50.A) .
  • In all non-residential districts (e.g., C, CM, M, PF), rebuilding is allowed only if damage is ≤ 50% of the structure’s appraised value and work starts within 1 year and proceeds diligently (§ 5080.50.B–C) . Appraised value rules and required scope limits also apply (§ 5080.50.D–F) .

• Structures under construction when rules changed

  • If a valid permit was issued before the ordinance took effect, construction can be completed and the structure used per current rules so long as it is finished within fixed time limits tied to height and floor area (generally 1 year for <3 stories/≤70,000 sf; 1.5 years for 3–6 stories/100,000–150,000 sf; 2 years for 7+ stories/≥150,000 sf; with limited monthly extensions) and complies with all other laws (§ 5080.60) .

• Adding a new use on a site with a nonconforming use

  • Maywood bars additional uses/structures on the same parcel unless the site can be legally subdivided to isolate the conforming and nonconforming components. The new use may only go on the portion that does not support the nonconforming use/structure (§ 5080.70) .

• Termination and amortization

  • Termination by discontinuance: 6 months of continuous discontinuance ends the right to operate (§ 5080.80.A) .
  • Termination by amortization: Two schedules apply, with specific timeframes based on when and how the nonconformity arose. Notably:
    • Residential uses or structures in R-3 that are nonconforming only for development standards (lot size/width, yards/setbacks, height, lot coverage, density, separation, open space, landscaping, or parking) are exempt from amortization (§ 5080.80.B, preface) .
    • One to five residential units on a parcel in C or CM (whether standalone or mixed with other uses) must terminate within 30 years (with notice recorded) unless a longer period applies by building-type schedule (§ 5080.80.B.2.f) .
    • Building-type amortization for structures not otherwise listed sets periods such as 25–50 years depending on construction type and use, and never less than 20 years (§ 5080.80.B.2.h, (3)–(4)) .
    • Any nonconformity created by the current ordinance or a later amendment must be cured, removed, or discontinued within 5 years, unless that adopting ordinance sets a different time (§ 5080.80.B.3) .
  • Public utilities and publicly-owned uses are not subject to nonconforming provisions, except they cannot add new nonconformities or enlarge the nonconforming site (§ 5080.80.C) . Nonconforming educational institutions (public or private) are fully exempt (§ 5080.80.E) .

• Extensions and revocations

  • Property owners may seek time extensions for amortized nonconformities by application to the Commission/Council, with findings required to avoid an unconstitutional taking or adverse neighborhood impacts (§ 5080.90.A–D) .
  • Independently, the City can revoke or modify a nonconforming use after hearing for reasons including fraud, non-use for 1 year or more, violations, or detriment to health/safety (§ 5150.10–.40) .

• Ordinance effect and cross-references

  • The ordinance limits premises to specifically permitted uses (§ 1010.50) and carries forward lawful nonconformities created by the ordinance with amortization measured from the date the nonconformity was created (§ 1020.40) .
  • Nonconforming signs are addressed separately under the sign chapter (§ 4110.80) ; see Maywood Signage.

Practical nuances that matter in Maywood

• Bringing nonconforming parking into compliance is a frequent condition for any expansion. Check current parking counts, layout, and loading standards before designing an addition (§ 5080.40.B) .
• If your project needs exterior changes, confirm any required design review or site plan review still applies to the new work (independent of nonconforming status) (see § 5110–§ 5130 index) .
• For ADUs, state law limits the City’s ability to deny permits due to existing zoning nonconformities that don’t pose a health/safety threat; coordinate early if your lot has legacy issues (HCD ADU Handbook; Gov. Code references) . See Maywood ADUs.

Checklist

• Establish the use/structure was legally created and not otherwise illegal when established (prove legal nonconforming status) (§ 5080.10) .
• Confirm no enlargement of nonconforming use/area is proposed unless squarely allowed by § 5080.40 (parking upgrades, additions meeting current standards) .
• If casualty damage occurred, document the date, appraised value, percent of damage, and start construction within the 1‑year window; keep diligent progress records (§ 5080.50) .
• If the use has ceased, verify whether the 6‑month discontinuance rule has been triggered (§ 5080.80.A) and be aware of separate 1‑year non-use as a revocation ground (§ 5150.10.C) .
• Check whether an amortization deadline applies (e.g., residential units in C/CM at 30 years) and calendar any required extension filing before expiration (§ 5080.80.B.2.f; § 5080.90.A) .
• If adding a new conforming use to a site with a nonconformity, test whether a legal subdivision can isolate it (§ 5080.70) .
• Verify if public utility/publicly-owned or educational exemptions apply (§ 5080.80.C, E) .
• Coordinate any related variances/exceptions or signage issues separately (see § 5100; § 4110.80) .

Risks & Ambiguities

Plain-English Summary

If your property in Maywood doesn’t meet today’s zoning, you may keep using it for a time, but you can’t expand it unless you meet specific conditions (often upgrading parking and meeting current setback/height rules for any new additions). Stop using a nonconforming use for six months and you lose it; some uses phase out on a fixed schedule. Apartments in R‑3 get special protection if they only miss current development standards, while homes grandfathered into commercial zones face a 30‑year sunset. When in doubt, document legality, watch your timelines, and talk to the City early.
