Redondo Beach — Nonconforming Uses

Nonconforming Uses under the Redondo Beach local zoning and planning code, with the controlling citations.

Last reviewed: July 2, 2026

Overview

This page explains how Redondo Beach treats nonconforming uses, nonconforming structures, and nonconforming lots under the Redondo Beach Municipal Code (Title 10 zoning chapters often titled “Title 17 / Zoning” historically). It summarizes what the code allows, what triggers loss of a nonconforming right, how repairs or additions are handled, and which code sections to read for a parcel-specific answer. Key municipal rules are reproduced here as plain‑English guidance and are grounded in the cited code sections below.

What the code says (core rules, plain-English)

A lawful nonconforming use may remain in place but generally cannot be structurally altered except as allowed by the code; additions or changes that would increase the degree of nonconformity are limited and require planning review (§ 10-5.2002) .
Minor structural alterations or small additions to a nonconforming use can be approved, but only subject to Planning Commission Design Review and meeting the explicit criteria in the ordinance (no increased nonconformity in density, height, FAR, parking; no adverse impacts; consistent with the General Plan / Local Coastal Program) (§ 10-5.2002(b)) . The code references Design Review procedures for those reviews (§ 10-5.2502 referenced in § 10-5.2002(b)) .
If a nonconforming use stops for a continuous period of two years, it automatically expires and cannot be reinstated (§ 10-5.2002(d)) .
Where the structure is nonconforming (i.e., a conforming use sits in a building that does not meet development standards), the structure may continue but additions must not increase the degree of nonconformity; floor‑area additions must meet full zone requirements and must not increase nonconformity (§ 10-5.2004) .
A structure that is involuntarily destroyed to the extent of 50% or more of its square footage generally may not be re‑established as a nonconforming structure — reconstruction is required to conform — though the code contains limited exceptions for multi‑family projects and single‑family dwellings in residential zones (§ 10-5.2004(c)) .
Nonconforming signs and billboards have separate rules; billboards may be required to be removed on specified triggers (change of use, destruction percentages, cessation, amortization deadlines) (§ 10-5.2006; § 10-5.1816) .
Minimum lot creation standards and when dwellings on substandard lots may be rebuilt are in the lot standards article; minimum lot area in residential zones is 5,000 sq ft (with R‑1A exceptions) for new lots in the Coastal Zone; parcels that were legally improved before certain historic cutoff dates have limited rebuild rights under nonconforming rules (§ 10-5.1528) .

Note: the code treats "nonconforming use" and "nonconforming structure" separately and applies different rules depending on whether the use was lawful when established and whether the nonconformity is a use vs. a development standard violation (§ 10-5.2002; § 10-5.2004) .

District-by-district breakdown (how nonconforming rules interact with common Redondo Beach zones)

The Redondo Beach code uses many specific zone labels. Below are the principal zones and how the nonconforming rules commonly intersect with each. Where the ordinance lists permitted uses or purpose, I cite it; where the code does not include a numeric standard in the retrieved materials, I mark that item “Not found in retrieved materials” and direct you to verify with the jurisdiction.

Important: nonconforming rules (Article 8) apply citywide but operate differently depending on whether the problem is a nonconforming use or a structure that fails current development standards (for which § 10-5.2004 controls) .

R-1 (Single‑Family Residential)

Purpose: Provide areas for single‑family dwellings and compatible public/semi‑public uses (see § 10-2.501 / § 10-5.501) .
Typical permitted uses: single‑family residential, family day care homes, residential care (limited), supportive/transitional housing where listed (R‑1 use table) (§ 10-2.501 / § 10-5.501) .
Key dimensional standards: minimum new residential lot size generally 5,000 sq ft per lot standards for residential zones; R‑1A is an exception (smaller minimums) (§ 10-5.1528) . Front/side/rear setback averaging and projection rules apply across residential zones (§ 10-2.1520; § 10-2.1522) .
Where it applies: Citywide residential areas mapped as R-1 per zoning map (designation § 10-5.300 list) .
Nonconforming interactions: single‑family dwellings destroyed <50% may be rebuilt to prior setbacks and sizes within 10% constraints; rebuilding after >50% destruction typically requires bringing the structure into conformance except limited exceptions for single‑family in residential zones (§ 10-5.2004(c)(2)) .

R-2 / R-3 / RMD / RH (Lower‑ to High‑Density Multi‑family)

Purpose: accommodate multi‑family housing at varying densities and protect residential character (see § 10-5.300 and the R‑zone use tables) .
Typical permitted uses: multi‑family dwellings, second units / ADUs under specified rules, family day care homes, some institutional uses as conditional (use tables) (§ 10-2.1526 and R‑zone use tables) .
Key dimensional standards: lot, setback, and unit‑separation rules (e.g., minimum 20 ft between detached dwellings on same lot) and other development standards apply; see general setbacks and lot standards (§ 10-5.1502; § 10-5.1528) .
Nonconforming interactions: The code specifically allows reconstruction of some multi‑family projects to the original number/size of units after partial destruction with parking replacement requirements; otherwise the >50% rule applies (§ 10-5.2004(c)(1)) .

C-2 / C-3 / C-4 / C-5 / CC (Commercial & Coastal Commercial)

Purpose: supply locations for retail, services, visitor‑serving uses (CC zones have special coastal criteria) (designation § 10-5.300) .
Typical permitted uses: retail, restaurants, offices (with CC restrictions on ground‑floor offices), visitor uses; large tenant spaces often conditional (CC zone rules § 10-5.811) .
Key dimensional standards: commercial zone bulk/setback rules are zone‑specific (not fully listed in retrieved snippets); see the zone tables for exact per‑zone standards. Not found in retrieved materials for every zone‑specific numeric standard — Verify with the jurisdiction.
Nonconforming interactions: nonconforming commercial uses may continue but structural changes that increase nonconformity (height, FAR, parking) are restricted and typically require design review (§ 10-5.2002(b)) .

MU‑2 / MU‑3 / CR (Mixed‑Use)

Purpose: permit integrated residential / commercial / public uses; encourage vertical or horizontal mixed use (designation § 10-5.300) .
Typical permitted uses: mixed commercial/residential developments, subject to the mixed‑use land‑use tables (specifics in Article 2).
Nonconforming interactions: mixed‑use projects follow the same nonconforming structure/use rules; additions that increase the degree of nonconformity are limited and design review applies (§ 10-5.2002; § 10-5.2004) .

I-2 / Industrial Zones

Purpose & uses: industrial, manufacturing, and other service uses allowed per the I‑zone use lists (see I‑zone use table § 10-5.1010) .
Nonconforming interactions: nonconforming industrial uses/signs are handled under the same Article 8 rules; billboards are explicitly addressed (§ 10-5.2006) .

Overlay Districts (Historic (H), PLD, MU overlay, Riviera (RIV))

Purpose: overlays add supplemental rules to the underlying zone. For example, the (H) Historic Overlay preserves historic buildings by allowing alternative uses but does not replace underlying zone standards (§ 10-5.1400; § 10-5.1410) .
Nonconforming interactions: where an overlay is imposed the underlying zone standards remain in force and nonconforming rules still apply; check the overlay section and the underlying zone for specific rebuild or alteration allowances (§ 10-5.1410) . See the city’s overlay districts page for context.

Most decision‑relevant standards (quick table)

Topic / Decision point	Rule (code citation)
Can a nonconforming use continue as‑is?	Yes, but generally no structural alterations except those required by building official or approved under nonconforming rules — § 10-5.2002(a)
Change from one nonconforming use to another	Allowed only if both uses are in the same class and the proposed does not require more parking — § 10-5.2002(a)(2–3)
Structural alterations / minor additions to a nonconforming use	May be approved subject to Planning Commission Design Review and criteria (no increased nonconformity, no parking loss, no adverse impacts) — § 10-5.2002(b)
Discontinuance / Abandonment rule	Continuous suspension/discontinuance ≥ 2 years causes automatic expiration — § 10-5.2002(d)
Destruction threshold for rebuilding	If structure destroyed ≥ 50%, nonconforming use/structure may not be re‑established; new structure must conform (exceptions for some residential and multifamily cases) — § 10-5.2004(c)
Floor‑area additions to nonconforming structure	Additions must meet zone requirements and not increase overall nonconformity; limited parking exceptions may apply on a director determination — § 10-5.2004(b)
Nonconforming signs / billboards	Regulated separately; replacement, maintenance, amortization and removal triggers described — § 10-5.2006; § 10-5.1816
Lot creation/minimums (residential)	Minimum lot area for residential zones 5,000 sq ft (R‑1A exception smaller) — § 10-5.1528

Checklist (what an applicant must satisfy to propose an alteration, rebuild, or change)

Confirm the use/structure was lawfully established (document prior permits/occupancy) — verify legal nonconforming status (§ 10-5.2002) .
Determine whether the issue is a nonconforming use (use itself illegal now) or a nonconforming structure (building fails development standards); the applicable rules differ (compare § 10-5.2002 and § 10-5.2004) .
If proposing structural changes or additions, prepare materials for Planning Commission Design Review and show how criteria in § 10-5.2002(b) will be met (no increased nonconformity in density/height/FAR/parking; no adverse impacts) . See the city's design review page for process.
Show parking analysis: that the proposed change does not require more off‑street parking than the existing nonconforming use or that any deficiency will not be increased (§ 10-5.2002(a)(3); § 10-5.2002(b)(3–4)) . Consult the city's parking rules.
If rebuilding after damage, determine percent destroyed: if ≥ 50%, anticipate needing to bring the reconstructed building into conformance except where the code provides a narrow exception (multi‑family and some single‑family residential exceptions) (§ 10-5.2004(c)) .
For lot questions (lot splits or substandard lots), confirm minimum lot standards and coastal‑zone special rules (§ 10-5.1528) .
Check overlays or historic designations that add rules (e.g., (H) Historic Overlay) — overlay rules supplement the underlying zone and can affect nonconforming treatments (§ 10-5.1410) .
Obtain any required modifications, variance, or administrative approvals — see variances & exceptions and the code sections referenced above.
Verify any building work will comply with the California Building Standards Code (Title 24) at permit stage — the zoning nonconformance rules do not replace building‑code compliance.

Risks & Ambiguities

Issue	Why it matters	What to verify
Is the use truly “lawful when initially established”?	The code protects only lawful pre‑existing uses; an unlawful use has no nonconforming protection (§ 10-5.2002)	Check permit/occupancy records and code history; verify with the Community Development Director.
Has the nonconforming use been discontinued for ≥ 2 years?	If yes, the nonconforming right expired automatically — owner cannot reinstate (§ 10-5.2002(d))	Verify business license records, utility records, and physical evidence of continuous operation.
Does the proposed change increase the “degree of nonconformity”?	The code prohibits alterations that increase nonconformity (density, height, FAR, parking) and may deny design review (§ 10-5.2002(b))	Show calculations for FAR, height, density and parking; compare to current zone standards in development standards.
Was the structure destroyed ≥ 50%?	≥50% destruction typically requires reconstruction to conform; exceptions are limited and complex (§ 10-5.2004(c))	Obtain an independent damage assessment and consult the Building Official and Planning staff.
Does an overlay (Historic, PLD, RIV) change re‑build or alteration rights?	Overlays impose additional rules and may allow or restrict alternative uses (§ 10-5.1410)	Review overlay chapter that applies to the parcel and consult planning staff.
Parking shortfall from prior construction	Off‑street parking is a common constraint — the code limits additions that would worsen parking deficiency (§ 10-5.2002(a)(3); § 10-5.2004(b))	Prepare a parking study and check whether shared/recorded parking arrangements exist.

If a matter is parcel‑specific or ambiguous in the facts, the code directs that the Community Development Director or Planning Commission interpret/apply the provisions — "Verify with the jurisdiction."

Plain‑English summary

Redondo Beach lets legally established nonconforming uses and buildings stay, but it limits repairs, additions, and replacements so nonconformities don’t get worse or last forever — structural changes are tightly controlled, long interruptions can kill a nonconforming right (two years), and heavy damage (about half the building) usually forces you to rebuild to current rules (§ 10-5.2002; § 10-5.2004) .

Frequently asked questions

How long can a nonconforming use remain in Redondo Beach?

A lawful nonconforming use may continue indefinitely so long as it is not structurally altered (except as allowed) — but if the use is suspended or discontinued for a continuous period of two years, it automatically expires and cannot be renewed (§ 10-5.2002(d)) .

Can I change a nonconforming use to a different nonconforming use?

Possibly — the code allows changing from one nonconforming use to another only if both are in the same class of zones, the proposed use is listed as permitted in that class, and the new use does not require more off‑street parking than the existing use (§ 10-5.2002(a)(2–3)) .

If my building was damaged, can I rebuild it exactly as it was?

If the building was involuntarily destroyed by disaster to the extent of 50% or more of its square footage, the reconstructed building generally must conform to current zone requirements and cannot simply re‑establish the nonconforming structure; there are limited exceptions for some multi‑family projects and single‑family dwellings in residential zones (§ 10-5.2004(c)) .

Can I add floor area to a nonconforming building?

Floor‑area additions are allowed only if they do not increase the overall degree of nonconformity (density, height, FAR, parking) and in many cases must meet the full zone requirements; specific exceptions for parking compliance may be available by director determination (§ 10-5.2004(b)) .

What happens if I want to remodel a nonconforming commercial tenant space?

Structural alterations or minor additions to a nonconforming use can be approved, but are subject to Planning Commission Design Review and the ordinance criteria — you must show the alteration will not increase nonconformity, will not reduce future parking capability, and will not adversely impact surrounding properties (§ 10-5.2002(b)) .

Do nonconforming signs get grandfathered?

Legal nonconforming signs are allowed normal maintenance and copy changes; replacement and larger changes are governed by the sign code and design‑review thresholds — billboards have specific removal triggers (change of use, destruction thresholds, cessation, amortization deadlines) (§ 10-5.1816; § 10-5.2006) .

Is my substandard lot eligible for rebuild if it’s smaller than current minimums?

Parcels created and improved with dwellings prior to specified historic cutoff dates may be rebuilt, remodeled, or expanded under the nonconforming structure rules; new lot creation must meet the minimum lot sizes (residential minimum generally 5,000 sq ft, R‑1A exception) (§ 10-5.1528) .

Do nonconforming rules affect adding an ADU?

The zoning nonconformance rules can affect how an ADU interacts with existing nonconforming conditions (e.g., parking, setbacks). State ADU law also applies; for local ADU rules see the city's ADU policy and the code on accessory dwelling units (see § 10-5.1506 and state law). Verify with planning staff as parcel specifics and state law interaction can change the path forward (§ 10-5.1506) .

If I want to expand a nonconforming structure but lack full parking, can I still proceed?

The code allows floor‑area additions only if the addition does not increase the degree of parking deficiency; for residential additions there is an avenue where the Community Development Director can determine a parking exception if on‑site parking cannot physically be located (§ 10-5.2004(b)) . You will need to document the parking constraints and likely go through design review.

Who interprets ambiguous nonconforming questions for my parcel?

When uncertainty exists, the Community Development Director is given authority to interpret the zoning provisions and keep a public record of those determinations; appeals or discretionary items may go to the Planning Commission (rules for interpretation / record‑keeping § 10-5.202) .
