Overview

Bradbury regulates nonconforming uses, structures, and parcels in Title IX of the Bradbury Development Code. Chapter 10 sets the citywide rules for when a nonconforming situation may continue, how and when it must end, and what work is allowed to a nonconforming building without increasing its noncompliance. This page distills those Bradbury-specific rules and shows how they interact with each zoning district and key development standards.

Use this with the city’s general Bradbury zoning & planning overview, the map and rules in Bradbury Zoning, your applicable Bradbury Land Use district, and the dimensional rules in Bradbury Development Standards.

What “nonconforming” means in Bradbury

  • Chapter 10 applies to legal nonconforming uses only, and applies citywide across all zones. A “legal nonconforming” use or structure is one that was lawful when established but no longer conforms to current regulations for the zone. Illegal past uses do not become “legal nonconforming” by adoption of the present code. See purpose/applicability and definitions in the code.
  • While a nonconforming use/structure exists on a lot, no new use, building, or structure may be established unless expressly allowed by Chapter 10.

Core citywide rules (Chapter 10)

  • Continuation allowed, but limited: A legal nonconforming use/structure may continue subject to Chapter 10 and its time limits; no alteration, addition or enlargement is allowed unless specifically permitted in §9.10.030(c).
  • Ordinary repair and maintenance: Allowed up to an aggregate of 50% of the structure’s then assessed value per calendar year. “Assessed value” is as shown on the current assessment roll.
  • Partial destruction: If a nonconforming building is damaged by casualty, it may be restored to its pre-casualty condition if total reconstruction cost does not exceed twice the then assessed value, and all work is completed within one year of the casualty.
  • Permitted work on nonconforming structures (§9.10.030(c)):
    • Eliminate the nonconformity.
    • Comply with laws enacted after adoption of the chapter (other than development code regulations).
    • Parking-only nonconformity for residential uses: work is allowed without meeting current off-street parking if it does not add units; if units are added, all units must meet current parking per Title IX.
    • Reconstruction exceeding 50% of assessed value is allowed if the new building does not change or intensify the prior use.
  • Effect of work: Allowed repair/work does not extend the nonconforming use’s termination date; owners must submit a written statement acknowledging that the new/repaired structure has the same termination date as the replaced building.
  • Exemptions and exceptions:
    • Buildings under construction with a valid pre-existing permit may be completed per their approved plans.
    • Public utility facilities directly rendering service may expand/modernize/replace equipment without triggering the partial-destruction removal rule, though non-direct uses (e.g., warehouses) are not exempt from nonconformity regulations.
    • Public acquisition (eminent domain/dedication) that renders a lot or portion nonconforming will not, by itself, create a nonconforming status; if later wholly destroyed, reconstruction must comply with code.
  • Loss of nonconforming status; termination (§9.10.040):
    • Immediate termination if there is a violation of law, a change from one nonconforming use to another, any enlargement/intensification of nonconforming use area/volume (unless allowed), conversion to a conforming use, or “abandonment” with discontinuance for 6+ months (rebuttable presumption of intent to abandon).
    • Termination by operation of law after certain periods measured from the date the use/structure became nonconforming, including:
      • Unimproved property (no permit-required structures): 1 year.
      • Unimproved except buildings/structures <500 SF GFA: 3 years.
      • Total assessed valuation of all improvements ≤$500 at time of nonconformity: 3 years.
      • Signs: varying phase-out periods (see Table below).
      • Nonconforming use in a conforming building: 5 years.
      • Nonconforming buildings/structures: abatement deadlines by building type I–V as defined by the City’s building regulations.
    • Abatement orders and appeals: The City Manager issues a written abatement order; appeal must be filed with the City Clerk within 30 days; the City Council holds a noticed public hearing and its decision is final.
  • Existing CUP-uses not deemed nonconforming by Chapter 49: If a use now requires a conditional use permit (CUP) under Chapter 49 but was lawful on the effective date, it is not “nonconforming” solely for that reason. However, if such buildings are partially destroyed (per §9.10.030(b)(4)) or expanded beyond §9.10.030(c), the use must obtain a CUP or be terminated.
  • Damaged nonconforming buildings or buildings on nonconforming lots (§9.10.060): May be reconstructed if (1) allowed by the building code, (2) started within two years and diligently completed, (3) does not extend any termination date nor increase the degree of nonconformity, and (4) the footprint and building envelope match the former building; if they exceed/deviate, all applicable current requirements and discretionary approvals apply.

Decision table: Nonconforming time limits and key thresholds

Note: Building “types I–V” are defined by the City’s building regulations; see the California Building Standards Code for overarching state standards.

How district rules interact with nonconforming rules

Bradbury’s nonconforming chapter applies to all zones, but each district has its own purpose, typical uses, and dimensional standards that define what it means to become conforming again. Use your district’s baseline rules below in tandem with Chapter 10 and any applicable design review, overlay districts, and landscaping and screening requirements.

R-7,500 Single-Family Residential (R-7,500)

  • Purpose: Protect and develop single-family neighborhoods.
  • Typical permitted uses: One single-family dwelling; small residential care; group homes; supportive/transitional housing; employee housing; plus accessory uses such as accessory living quarters and ADUs under Chapter 85.
  • Key dimensional standards: 7,500 sf minimum lot area; 60 ft average lot width and 45 ft min frontage; setbacks of 20 ft front (second story 25 ft), 10 ft sides (second story 20 ft), 10 ft rear (second story 30 ft); dwelling minimum 1,500 sf; two-story FAR and lot coverage limits; height limits consistent with ridgeline regulations, generally one story and 28 ft, with the principal dwelling allowed two stories.
  • Nonconforming-specific district tools:
    • Existing uses exemption (pre-code structures not deemed NC solely by chapter adoption).
    • Additions to NC buildings allowed where the NC is only yards or certain access/drive widths, if built to the setback standards in effect at time of original construction and not increasing the degree of NC.

R-20,000 Single-Family Residential (R-20,000)

  • Purpose: Single-family neighborhoods at larger lot sizes.
  • Typical permitted uses: One single-family dwelling; small residential care; group homes; supportive/transitional housing; with accessory living quarters/ADUs per Chapter 85; certain explicit prohibitions (e.g., short-term rentals).
  • Key dimensional standards: 20,000 sf minimum lot area; 80 ft average lot width and 60 ft min frontage; 35 ft front, 15 ft sides, 15 ft rear; private street building setbacks of 50 ft.
  • Nonconforming-specific district tools:
    • Existing uses exemption and “additions to NC buildings” parallel to R-7,500.

A-1 Agriculture Residential Estate (A-1)

  • Purpose: Single-family residential estate character (one-acre lots).
  • Typical permitted uses: One single-family dwelling; agricultural garden uses; small residential care; group homes; supportive/transitional housing; employee housing; plus accessory living quarters and ADUs.
  • Key dimensional standards: 1 acre minimum lot; 100 ft average lot width and 75 ft min frontage; 50 ft front, 25 ft side, 25 ft rear; minimum dwelling 2,250 sf; height limited by ridgeline regulations or to 28 ft; off-street parking required.
  • Nonconforming-specific district tools:
    • Existing uses exemption and “additions to NC buildings” for yard/access nonconformities.

A-2 Agriculture Residential Estate (A-2)

  • Purpose: Single-family residential estate character (two-acre lots).
  • Typical permitted uses: One single-family dwelling; agricultural garden uses; small residential care; group homes; supportive/transitional housing; employee housing; plus accessory living quarters and ADUs.
  • Key dimensional standards: 2 acres minimum lot; 120 ft average lot width and 90 ft min frontage; 50 ft front, 25 ft sides, 25 ft rear; 50 ft from private streets/vehicular easements.
  • Nonconforming-specific district tools:
    • Existing uses exemption and “additions to NC buildings” for yard/access nonconformities.

A-5 Agriculture Residential Estate (A-5)

  • Purpose: Estate-scale single-family areas.
  • Typical permitted uses: One single-family dwelling; agricultural garden uses; small residential care; group homes; supportive/transitional housing; employee housing; plus accessory living quarters and ADUs.
  • Key dimensional standards: Not found in retrieved materials. Basic placement and existing-use exemptions mirror other estate districts; off-street parking required.
  • Nonconforming-specific district tools:
    • Existing uses exemption and “additions to NC buildings” for yard/access nonconformities.

OS Open Space (OS)

  • Purpose: Conserve areas where structural use may endanger health/safety or where resource preservation is needed.
  • Typical permitted uses: Public/private dedicated open spaces; propagation nurseries/horticulture (no dwellings or on-premises sales/advertising). Conditional public facilities (e.g., flood control, parks, water facilities, utility substations) via CUP.
  • Key dimensional standards: No lot area/dimension limits; no residential density; building coverage ≤10%; height ≤18 ft.
  • Nonconforming-specific district tools:
    • Citywide Chapter 10 applies; OS also lists expressly prohibited uses (including residential).

Special cross-overs that matter for nonconformities

  • Secondary Units and SB 9: Chapter 85 governs ADUs, JADUs, Accessory Living Quarters (ALQ), and SB 9 housing. Bradbury codifies that an ADU/JADU application cannot be denied just because of a nonconforming zoning or building condition unless it presents a health/safety threat and is affected by the ADU work. For ALQs, older legally permitted units (pre-1/1/2020) may remain as legal nonconforming, and nonconforming ALQs cannot be expanded unless brought into compliance. See Bradbury ADUs and related state context in California ADU law.
  • Signage: Nonconforming signs are phased out on specific timeframes; see Bradbury Signage for broader sign rules, but the termination periods are in §9.10.040.
  • Overlays: Bradbury’s Affordable Housing Overlay (AHO) and Affordable Housing Civic Center Overlay (AHCCO) layer on top of base zones; if a conflict is perceived, the overlay controls. See Bradbury Overlay Districts.
  • Conditional Uses: Some public/utility and OS uses require CUPs; if your use transitions from “by-right” to “CUP-required,” §9.10.050 outlines when you must secure a CUP after partial destruction or enlargement. See Bradbury Variances and Exceptions for broader relief mechanisms, and Chapter 49 for CUPs.
  • Design/landscape interfaces: Height, ridgeline, and yard-improvement standards appear across districts and in design review tools. Coordinate nonconforming work with Bradbury Design Review and Bradbury Landscaping and Screening as applicable.

Checklist

  • Confirm the use/structure is a legal nonconforming situation under Title IX (not an illegal use trying to “become” legal).
  • Identify your base zoning district and dimensional standards; determine what must change to become conforming.
  • If proposing repairs/alterations, ensure the scope fits §9.10.030(b)–(c) and does not increase the degree of nonconformity.
  • For residential parking-only nonconformities, verify whether unit count is increasing; if yes, bring all units up to current parking standards.
  • For partial destruction, verify assessed-value thresholds and complete within the required timeframe (1 year under §9.10.030(b)(4) or 2 years under §9.10.060, depending on situation).
  • Before a building permit, provide the City the required owner statement acknowledging no extension of the nonconforming termination date.
  • If an abatement order is issued, calendar the 30-day appeal period and prepare evidence for the City Council hearing.
  • If a pre-existing use is now CUP-required, evaluate whether partial destruction or enlargement triggers the need to obtain a CUP under §9.10.050.
  • If an overlay applies (e.g., AHO/AHCCO, SP overlay), confirm which standards control.
  • For ADUs/JADUs/ALQs, confirm ministerial approval criteria and nonconforming-conditions limits in Chapter 85.

Risks & Ambiguities

Issue Why it matters What to verify
Assessed value calculations Triggers 50% maintenance cap and 2x-value casualty threshold Work with the City on the “then assessed value” from the current assessment roll at time of repair/casualty.
Building type (I–V) classification Sets abatement deadlines for nonconforming buildings Confirm building type “as defined by the City’s building regulations.”
Six-month abandonment presumption Loss of nonconforming status Evidence to rebut presumption (e.g., continuous operations, intent to resume).
Enlargement/intensification May force termination Whether any increase in area/volume or use intensity is proposed.
Reconstruction footprint/envelope Deviations trigger full compliance Whether the new work exactly matches the pre-damage footprint/envelope (§9.10.060) or fits within §9.10.030 limits.
CUP-required uses When partial destruction/expansion occurs, CUP may be required If your use became CUP-required by Chapter 49, check §9.10.050 triggers.
Sign phase-out timing Deadlines vary by sign type Match your sign to the §9.10.040 schedule. See also Bradbury Signage.
Overlay conflicts Overlays can control over base zones Whether AHO/AHCCO or SP overlay standards supersede base rules.

Plain-English Summary

If your property or use was legal when established but no longer matches today’s zoning, Bradbury generally lets you keep using it for a time—so long as you don’t expand it, you follow strict repair/rebuild limits, and you don’t abandon it for six months. Fixes and even some reconstructions are allowed, but you typically can’t extend the life of a nonconforming use or make it more nonconforming. When you repair, the City will require a written acknowledgment that your nonconforming status won’t be extended. If the City orders abatement, you have 30 days to appeal to the City Council.

Frequently asked questions

How long can I keep a nonconforming use in Bradbury?

It depends on the situation. A nonconforming use in a conforming building must terminate within five years, while various time limits apply to unimproved property and small structures; certain building types have specific phase-out periods. Signs have their own phase-out schedule. See §9.10.040 for the complete list.

What happens if I stop operating my nonconforming use?

If a nonconforming use is discontinued for six months or more, there is a rebuttable presumption that you intended to abandon it, and the nonconforming status is lost. Resuming later could be unlawful without full compliance. See §9.10.040(1)(e).

Can I rebuild a nonconforming house after a fire?

Yes, with strict limits. For general partial destruction, you may restore to the prior condition if total reconstruction cost is no more than twice the assessed value and work is completed within one year (§9.10.030(b)(4)). For buildings on nonconforming lots, you may reconstruct if you start within two years and match the prior footprint/envelope (§9.10.060).

Can I add onto a structure that encroaches into setbacks?

Possibly. Each residential district includes an “Additions to a nonconforming building” section allowing additions where the only nonconformity is yards or certain access widths, if you build to the original era’s setbacks and do not increase the degree of nonconformity. See, for example, R-7,500 §9.61.070, R-20,000 §9.64.070, A-1 §9.67.070, A-2 §9.70.070, and A-5 §9.73.070.

Do I need a CUP to keep operating a use that is now CUP-required?

Not solely because the code changed. However, if the related building is partially destroyed (see §9.10.030(b)(4)) or enlarged beyond what §9.10.030(c) allows, you must secure a CUP under Chapter 49 or terminate the use. See §9.10.050.

Can I fix up a nonconforming building without triggering compliance?

Yes, ordinary repair/maintenance is allowed up to 50% of the building’s assessed value per calendar year. Work to remove nonconformities, comply with later-enacted laws, or reconstruct without intensifying the use can also be permitted—but it doesn’t extend the nonconforming termination date. See §9.10.030(b)–(d).

How are nonconforming signs handled?

They are phased out within defined timeframes by sign type (e.g., portable signs in 90 days; painted wall/window signs in six months; billboards at 10 years or five years from becoming nonconforming, whichever is later). See §9.10.040(2)(d).

What if my ADU application is on a lot with old zoning violations?

Bradbury codifies state law: the City cannot deny an ADU/JADU solely because of a nonconforming zoning or building condition unless it presents a health/safety threat and is affected by the ADU. See §9.85.115(b) and related Chapter 85 provisions.

Which zones in Bradbury allow single-family homes, and what are typical lot sizes?

All residential zones—R-7,500, R-20,000, A-1, A-2, and A-5—allow a single-family dwelling. Minimum lot sizes include 7,500 sf (R-7,500), 20,000 sf (R-20,000), 1 acre (A-1), and 2 acres (A-2). A-5 minimum lot size was not found in retrieved materials. See district chapters §§9.61, 9.64, 9.67, 9.70, 9.73.

Does design review affect nonconforming structures?

It can. Height and ridgeline/view preservation standards apply to many projects and can shape how a nonconforming structure is modified to become conforming. Coordinate early with Bradbury Design Review and your district’s development standards.
