Overview
Hawthorne regulates land use through the Hawthorne Municipal Code, Title 17 (Zoning), which sets the city’s base districts, overlays, procedures, and development standards. The code’s structure is conventional but with Hawthorne-specific layers like a Housing Overlay, Mixed-Use Overlay, and an Airport Master Plan that can supersede base-zone rules. Citywide rules for yards, height, development standards, parking, and design are distributed across zone chapters and common standards chapters. State housing mandates—California housing laws including SB 9, density bonus, and ADUs—operate alongside local provisions and, where required, are processed ministerially.
Key rule of precedence: If a specific plan or the Airport Master Plan applies, it controls over conflicting zoning rules; where it’s silent, Title 17 controls. See § 17.22.090 and § 17.22A.030.
How Hawthorne’s code is organized
- Title 17 begins with general provisions and definitions, then the zoning map and use classifications that frame where districts apply and how they’re interpreted (e.g., Chapter 17.02 General Provisions; 17.04 Definitions; 17.06 Administration; 17.08 Zoning Map; 17.10 Use Classification). Certificate of occupancy procedures appear in Chapter 17.12.
- Residential districts (R-1 through R-4) each have a chapter with a “Table of Uses and General Standards.” A citywide chapter supplements these tables with additional residential standards (Chapter 17.20).
- Commercial and industrial districts (C-1, C-2, C-3, CM, M-1) have their own chapters for use lists and bulk rules; C-2’s permitted/prohibited use lists are codified at §§ 17.26.020–.025; M‑1’s industrial purpose is at § 17.32.010.
- Overlays and special areas—Mixed-Use Overlay (Chapter 17.87), Housing Overlay (Chapter 17.85), Trucking-Intensive Overlay (Chapter 17.86), Specific Plans (Chapter 17.22), and the Airport Master Plan (Chapter 17.22A)—layer on top of base zones.
- Process chapters include design review (Chapter 17.99), conditional use permits and variances (Chapter 17.40), on-site parking (Chapter 17.58), fencing (Chapter 17.48), signage (Chapter 17.35), landscaping/water efficiency (Chapter 17.89), nonconformities (Chapter 17.38), and Objective Design Standards for multifamily/mixed-use (Chapter 17.100).
Zoning district families
- Residential: R‑1 (Low Density), R‑2 (Medium Density), R‑3 (High Density), R‑4 (Maximum Density). Each chapter sets minimum lot size, setbacks, lot coverage, height, and per‑unit open space where applicable. Examples: R‑1 standards are codified at § 17.14.020; R‑3 at § 17.18.020; R‑4 at § 17.19.020.
- Horticultural: H (Horticultural Classification) appears in Chapter 17.13.
- Commercial: C‑1 (Freeway Commercial/Mixed Use), C‑2 (Local Commercial), C‑3 (General Commercial) are referenced in the Mixed‑Use Overlay and have their own use/standards chapters (e.g., C‑2 permitted/prohibited uses at §§ 17.26.020–.025).
- Mixed-use base: CM (Commercial Mixed-Use classification) has development and process rules used for true vertical mixed-use projects (e.g., development standards and approvals reflected around § 17.29.050).
- Industrial: M‑1 (Limited Industrial) statements of purpose and permitted framework at § 17.32.010; other industrial classifications appear separately in Title 17.
Citywide development standards
At a high level, Hawthorne’s district tables and common-standards chapters set the baseline for setbacks, height, floor area, lot coverage, and parking, with additional rules in overlays and specific plans:
- Single-family benchmark (R‑1): The R‑1 district typically sets a 15 ft front setback, 5 ft interior and 10 ft street side setbacks, a 5 ft rear setback, 50% maximum lot coverage, and 22 ft maximum building height (§ 17.14.020).
- Multifamily benchmarks: In R‑3, multifamily has up to 45 ft height, 80% lot coverage, and 150 sf of open space per unit (§ 17.18.020). In R‑4, multifamily may reach 60 ft height, 80% lot coverage, and 150 sf open space per unit (§ 17.19.020).
- Commercial yardsticks: Chapter 17.28 sets a maximum FAR of 2.5:1 and no absolute height cap, but any building of 5+ stories needs a conditional use permit (§§ 17.28.050, 17.28.040).
- Residential-wide supplements: Chapter 17.20 applies to all residential zones; for example, it governs front-yard paving limits and yard encroachments for features like bay windows and patios (§§ 17.20.010, 17.20.030).
- Fences/walls and sight distance: Citywide fence location/height and corner visibility are governed by Chapters 17.48 and 17.42 (e.g., fence design and screening near residential zones at § 17.48.020; vision clearance at § 17.42.090).
- Parking: Baseline vehicle parking ratios live in Chapter 17.58 (e.g., Required Parking at § 17.58.020), and bicycle parking for multifamily/mixed-use is specified by the Objective Design Standards (§ 17.100.050).
Specific plans & overlays
- Specific Plans: Hawthorne lists seven adopted plans—Central Park (Parkside Village), Century Business Center, Downtown Hawthorne, Pacific Glen (360° at South Bay), Prestige Villas, Willow Glen (Fusion), Green Line Mixed Use—and allows new specific plans to supplant underlying zoning where adopted (§§ 17.22.070, 17.22.060, 17.22.090).
- Airport Master Plan (AMP): The Jack Northrop Field Hawthorne Municipal Airport Master Plan governs land use, height, and site design for the approximately eighty-acre AMP area; plan rules control over conflicting zoning, and all building permits in the AMP area require a consistency finding (§§ 17.22A.010–.040).
- Mixed-Use Overlay (MU): Applied over C‑1, C‑2, C‑3 corridors; where the overlay conflicts with base-zone rules, the overlay controls (§ 17.87.020). Focus areas include Hawthorne Blvd North/South, Marine Ave, and Imperial/Kornblum (§ 17.87.030). Core standards include min project area 1.5 ac, density up to 30 du/ac, building height to 60 ft/5 stories, ground-floor commercial setback 5–15 ft, and residential street setback 15 ft (§ 17.87.060).
- Housing Overlay (HO): Requires residential density between 20–30 du/ac, caps height at 60 ft, sets 15 ft residential street setbacks and 5–15 ft commercial frontage setbacks, and requires 150 sf open space per unit (§ 17.85.040).
- Trucking-Intensive Overlay: Provided in Chapter 17.86 (consult the map and chapter text when applicable).
Building permits & review
- Start with the zoning map and designation of zones (Chapters 17.08, 17.10), then verify allowed uses and district standards in your base zone and any applicable overlay or specific plan (§§ 17.08.020; 17.10.030–.040).
- Many exterior commercial changes require approvals; for example, commercial exterior colors must be approved (§ 17.30.010). True mixed‑use in the CM classification requires both Design Review Board approval and a conditional use permit before building/grading permits (§ 17.29.050).
- Design review approvals have durations and renewal provisions and may be modified or revoked if conditions aren’t met (§ 17.99.090). Chapter 17.99 also provides site-planning guidance used during review (§ 17.99.100).
- CUPs and variances are noticed, heard, and decided per Chapter 17.40, with findings and appeal procedures laid out in §§ 17.40.070–.110 and related sections.
- A certificate of occupancy is addressed in Chapter 17.12; coordinate with Building and Safety for permits under the California Building Standards Code.
State housing law in Hawthorne
- Density Bonus: Hawthorne implements Government Code § 65915 via Chapter 17.17, including the number of concessions and the city’s obligation to grant them unless specific adverse-impact findings are made (§ 17.17.040). Applications must include zone capacity and affordability details (§ 17.17.050).
- SB 9 (Urban Lot Splits & Two-Unit Developments): Hawthorne processes qualifying SB 9 applications ministerially, without hearings (§ 17.102.050). Key SB 9 site limits include location in a single-family zone, exclusions for historic resources, and demolition limits protecting recent or controlled-rent housing (§ 17.102.030). Objective standards include a 15 ft front setback and 4 ft side/rear setbacks, ≤22 ft height, ≥800 sf per new unit, and one parking space per unit unless near transit or car-share (§ 17.102.040).
- ADUs/JADUs: R‑1 explicitly cross-references the city’s ADU/JADU chapter for permissions (§ 17.14.020; “See 17.21”). JADUs require a recorded deed restriction before a building permit issues (§ 17.21.080). Where local code defers to state minimums, California ADU law controls.

Frequently asked questions
What zoning districts does Hawthorne have?
Hawthorne maps property into residential R‑1, R‑2, R‑3, R‑4; commercial C‑1, C‑2, C‑3 and CM mixed‑use; industrial such as M‑1; plus overlays (Mixed‑Use, Housing, Trucking‑Intensive) and adopted specific plans. Base zones and the zoning map framework are in Chapters 17.08 and 17.10, with district chapters setting use and standards; the Mixed‑Use Overlay cites C‑1/C‑2/C‑3 by name (§ 17.87.020).
What are typical setbacks and height for a single-family lot?
In R‑1, the table of standards sets a 15 ft front, 5 ft interior side, 10 ft street side, 5 ft rear setback, with 50% max lot coverage and 22 ft max height (§ 17.14.020). Citywide residential standards in Chapter 17.20 also apply (e.g., front-yard paving limits, bay-window encroachments).
Where are parking ratios and bike parking found?
Vehicle parking ratios and loading are in the On‑Site Parking chapter (e.g., Required Parking at § 17.58.020). Multifamily and mixed‑use projects must also meet Objective Design Standards for bicycle parking (e.g., one long-term bicycle space per dwelling unit) in § 17.100.050.
Do mixed-use projects need special approvals?
Yes—true mixed-use in the CM classification requires Design Review Board approval and a CUP before any building or grading permit, with specific findings listed at § 17.29.050. In the Mixed‑Use Overlay, overlay standards prevail over base zones (§ 17.87.020).
Can I split my R‑1 lot or add a second unit under SB 9?
If your site meets SB 9 location and tenant‑protection limits, Hawthorne must process an SB 9 two‑unit or urban lot split application ministerially (§ 17.102.050). Objective standards include 15 ft front and 4 ft side/rear setbacks, ≤22 ft height, ≥800 sf per new unit, and one off‑street space per unit unless near transit or a car‑share (§ 17.102.040); sites in historic districts are excluded (§ 17.102.030).
Are ADUs and JADUs allowed in single-family zones?
Yes—R‑1’s standards table directs ADUs/JADUs to Chapter 17.21 (§ 17.14.020). JADUs require a recorded deed restriction before a building permit can issue (§ 17.21.080). For minimum entitlements (e.g., at least one 800‑sf ADU with 4‑ft side/rear yards), see California ADU law.
How tall can mixed-use buildings be on Hawthorne Boulevard?
In the CM mixed-use framework, building height is generally capped at 60 ft/5 stories, with a targeted allowance up to 85 ft for portions of larger projects fronting Hawthorne Boulevard (subject to the chapter’s criteria). See the CM development provisions reflected with the CM approvals at § 17.29.050.
Where do I find sign rules and design review?
Signs require a sign permit under Chapter 17.35 (e.g., § 17.35.010), and many commercial exterior changes need color approval (§ 17.30.010). Design review procedures, timelines, renewals, and site-planning guidelines are in Chapter 17.99 (§§ 17.99.090–.100).
Does Hawthorne have rent control?
Not found in the source materials for Title 17. Check the broader municipal code or city programs for any rent stabilization; statewide limits may apply via California housing laws. Not found in source materials.
