Agoura Hills — Nonconforming Uses

Last reviewed: July 3, 2026

Overview

Agoura Hills regulates nonconforming lots, buildings, uses and related features in Article IX (Zoning), primarily in the nonconforming chapter (Parts 1–12, §§ 9701–9711). The ordinance divides nonconformities into Type I (nondetrimental) and Type II (detrimental) categories and sets different continuation, alteration, amortization, repair and abandonment rules for each. This page summarizes what the Agoura Hills Municipal Code requires, district‑specific development standards that interact with nonconforming status, and the key decision points applicants must verify with the Planning & Community Development Department. Always verify with the jurisdiction for parcel‑specific determinations. § 9701–9709

How Agoura Hills structures nonconforming rules (core points)

• Purpose: city treats existing legal-but-now-nonconforming lots/buildings/uses as nonconforming to protect public welfare while setting rules for continuation, amortization, repair and conversion. § 9701
• Two classes:
  • Type I — nondetrimental: may generally continue and may be improved/altered subject to district rules; includes many residential lot/height/yard nonconformities. § 9702
  • Type II — detrimental: subject to termination or removal on an amortization schedule (10–20 years depending on construction type); Type II uses must cease or convert within prescribed periods. § 9703
• Specific rules for land-only uses, parking, outdoor storage, performance nonconformance and wireless facilities are provided (see § 9704–9707, § 9705–9706, § 9707, § 9711).
• Modifications, moving buildings, reconstruction after damage, and abandonment are explicitly regulated: e.g., moving a nonconforming building requires bringing it into full compliance; nonconforming residential structures may be rebuilt up to 100% of pre‑damage size if reconstruction begins within 1 year (extensions by director for good cause); nonresidential structures may be reconstructed up to 100% only if repair cost ≤ 50% of replacement cost, otherwise full compliance is required. § 9708.1; § 9708.3(A)–(B)
• Abandonment/discontinuance rule: continuous discontinuance for 180 days generally converts the property to conforming‑only uses thereafter. § 9702; § 9703; § 9704; § 9708.4

District-by-district notes (purpose, typical uses, dimensional standards, where it applies)

Below are Agoura Hills district summaries that are most relevant when assessing nonconformities. For each district I cite the district development standard section that defines setbacks, coverage, height or special overlay rules that interact with nonconforming treatment.

RS (Single‑Family Residential — RS)

• Purpose / typical uses: single‑family dwellings; SB9-related two‑unit rules apply to RS. § 9293
• Key standards: lots ≥ 10,000 sq ft have min front setback 25 ft and max building coverage 35%; lots < 10,000 sq ft have min front setback 20 ft and max coverage 50%; max height 35 ft (2 stories). § 9293.5
• Where it matters for nonconformities: buildings that fail RS height/yards are typically Type I (may continue but alterations must comply) while industrial/commercial buildings in RS would be Type II and amortized/terminated. § 9702; § 9703

RL (Rural Large‑lot Residential — RL)

• Purpose / typical uses: large single‑family lots, open‑space emphasis. § 9233
• Key standards: min front setback = 1.25 ft per vertical foot of height, min 25 ft; max site impermeable coverage 35%; max height 30 ft (2 stories). § 9233

RV (Single‑Family Estate — RV)

• Purpose / typical uses: estate single family homes. § 9293.7
• Key standards: min front setback 25 ft, max impermeable coverage 25%, max height 35 ft (2 stories). § 9293.7

RM (Residential‑Medium — RM)

• Purpose / typical uses: multifamily residential with densities shown by suffix (e.g., RM‑10). § 9253
• Key standards: minimum yards and lot sizes vary by RM suffix; typical front yard 15 ft, side 7 ft, height limits and coverage defined in § 9253. § 9253

CRS / CS / CS‑MU / Commercial Districts (e.g., CRS, CS‑MU)

• Purpose / uses: neighborhood and regional commercial, offices, services. § 9332–9333; § 9526.1
• Key standards (examples): CRS: min lot area 10,000 sq ft, max building coverage 60%, max height 35 ft, yards vary (front = building height or min 20 ft). § 9333
• Special AH overlay on CS‑MU sites sets FAR 0.4, front/side/rear setbacks 20 ft for many cases and other mixed‑use rules; these overlay standards control in conflict. § 9526.1

Business Park / BP (e.g., BP‑M, BP‑OR) and Freeway Corridor (FC) overlay

• Purpose / uses: office, business park uses; FC overlay modifies allowable uses adjacent to Ventura (101) Freeway. § 9542–9544; § 9661.20
• Key standards: FC overlay prohibits certain uses (adult uses, most off‑sale alcohol) and requires setbacks from freeway of 1 ft per 2 ft of height (min 20 ft) plus screening/landscape treatments. § 9544.1

PD (Planned Development — PD) and Specific Plan areas (Agoura Village)

• Purpose / typical uses: site‑specific regulations under a specific plan. PD developments must meet specific plan standards; many PDs require discretionary findings and may supersede chapter‑level standards. § 9498–9499

Old Agoura Design Overlay (OA) / Historic resources

• Purpose / typical uses: preserve Old Agoura character; some historic structures are given special treatment for reconstruction. § 9552–9553; § 9553.6
• Key standards: discretionary building coverage (usually ≤ 50%), heights normally ≤ 35 ft, and special materials and sign rules to preserve rural character. § 9553.1–9553.6
• Historic nonconforming nonresidential structures (identified by §) may be reconstructed to 100% pre‑damage area under § 9708.3(C) when they are listed in Old Agoura. § 9708.3(C)

Practical guidance — what this means on the ground

• If your building or use was legal when established but conflicts with a later zoning change, identify whether it is Type I or Type II under § 9702–9703. That classification determines whether you can improve, enlarge, or expect amortization. § 9702–9703
• Repairs after a fire or other calamity differ for residential vs. nonresidential structures — confirm reconstruction cost thresholds and time limits (1‑year start rule, 50% threshold for nonresidential). § 9708.3
• An apparently small change (e.g., moving a building on the lot or expanding outdoor storage) can trigger full conformance obligations. Moving is allowed only if the structure is brought into conformance. § 9708.1
• Overlay districts and special plans (e.g., Old Agoura, FC, AH overlay/CS‑MU) may impose standards or exemptions that supersede the base district; always check overlay provisions. § 9553; § 9542–9544; § 9526.1

Checklist (what an applicant must satisfy / document)

• Confirm legal establishment date and gather evidence (permits, business licenses, tax records) to prove lawful nonconforming status. § 9701; § 9703
• Determine whether the nonconformity is Type I or Type II using the code definitions and whether the use/building is “detrimental.” § 9702–9703
• If proposing repair, expansion or reconstruction, prepare a cost estimate and scope to check the 50% threshold (nonresidential) and the 1-year commencement rule (residential). § 9708.3(B)–(A)
• Identify applicable district standards (RS, RL, RV, RM, CRS, CS‑MU, PD, etc.) and overlay rules; collect required site plans showing setbacks, coverage and heights. § 9293.5; § 9233; § 9333; § 9526.1
• Check whether proposed work triggers compliance with off‑street parking, screening/landscaping, signage or design review requirements and prepare materials accordingly (see parking, design review, landscaping and screening, signage). § 9705; § 9553; § 9606
• If the property is in Old Agoura or a historic list, confirm whether historic reconstruction allowances apply and get required design approvals. § 9552.2; § 9708.3(C)
• For wireless or other specialized facilities, check the facility‑specific nonconforming timelines (longer compliance periods) and abandonment rules. § 9711; § 9661.16–.17

Risks & Ambiguities

Plain‑English Summary

If your building, lot or business in Agoura Hills no longer matches current zoning but was legal when created, the city treats it as a legal nonconformity and lets many such uses continue (especially nondetrimental ones), but some detrimental uses face time limits, repair restrictions, and reconstruction thresholds — check whether your property is Type I or Type II, whether overlay rules apply, and whether repairs or changes will trigger a requirement to make the property comply with current rules. § 9701–9708
