East Palo Alto Zoning, Planning & Building Codes

Last reviewed: July 3, 2026

Overview

East Palo Alto’s land-use rules are embodied in the City’s Title 18 — Development Code (adopted 2018). The Code organizes the city’s zones, development standards, permit procedures, and program-level rules (density bonus, ADUs, specific plans) and is intended to implement the General Plan and CEQA obligations (§ 18.02.010; § 18.02.020) . This page explains how the Code is organized, the citywide standards that apply everywhere, the local zoning district families (and key numbers), special plans and overlays, the permit paths you’ll use, and how California housing law commonly interacts with East Palo Alto rules.

How East Palo Alto's code is organized

• The code is published as Title 18 — Development Code; Article 1 (general provisions and definitions) starts with § 18.02.010 and § 18.02.020 and frames the Code’s authority and relationship to the General Plan and CEQA (§ 18.02.020) .
• Zoning districts, allowed uses, and per‑zone development standards live in Article 2 (e.g., Chapters 18.10–18.16) and the associated tables (Tables 2‑1 through 2‑6) (§ 18.10.030; § 18.12.030; § 18.14.030) .
• City‑wide (applies-in-all-zones) standards — setbacks, height measurement, corner vision triangle, screening, landscaping, lighting, etc. — sit in Article 3 (notably Chapter 18.22) (§ 18.22.010; § 18.22.020; § 18.22.030) .
• Rules for specific uses (outdoor dining, child day care, demolition/replacement, etc.) are in Article 4, Chapter 18.48 (§ 18.48.010) .
• Permit processing, discretionary review, and review authority tables are grouped in Article 7 (Chapters 18.80–18.100) including Zoning Clearances, Site Plan & Design Review, Administrative Use/Conditional Use Permits, Variances, Planned Developments, and subdivisions (§ 18.80.010; § 18.82.030; § 18.84.010; § 18.86.010) .

For quick navigation: the Code’s table of contents lists the Chapters and their key sections (see Article headers and chapter § numbers) — use the chapter numbers above to jump to the topic you need (§ 18.02.; § 18.06.; § 18.10–18.18; § 18.22; § 18.30; § 18.86; § 18.96) .

Zoning district families (citywide summary)

The Development Code groups districts into families and specific plan subdistricts. Below are the primary families and examples; each family’s numeric or alpha district and development rules are in the chapters cited.

• Residential zones — R-LD, R-MD, R-HD, R-UHD (standards summarized in Table 2‑2 and the Chapter 18.10 development standards) (§ 18.10.030) . Example controls: R-LD typical dwelling height 2 stories / 26 ft; parcel-area minima and front/side/rear setbacks are set in Table 2‑2 (§ 18.10.030; Table 2‑2) .
• Mixed‑use zones — MUC, MUL, MUH with tabled FAR and story/height limits in Chapter 18.12 (Table 2‑4). Examples: MUC up to 1.75 FAR and 5 stories / 60 ft; MUH up to 2.5 FAR and 8 stories / 100 ft (§ 18.12.030) .
• Commercial zones — C‑G, C‑N, C‑O (Chapter 18.14) with FAR (e.g., 2.0–3.0 FAR) and heights set by subzone — see Table 2‑6 for height and setback rules (§ 18.14.030) .
• Special‑purpose and other districts — examples include PI, PR, RM, and the Ravenswood plan districts (4C, BRC, REC, IT, WO, UR, UV, R‑OS, R‑FO) that operate as an overlay/specific plan (see Chapter 18.16 and Chapter 18.18) (§ 18.16.010; § 18.18.020) .
• Legacy or plan‑area keys (e.g., R‑1, R‑2, R‑M, UR, and ROS) are used in tables and the Ravenswood Specific Plan mapping; consult the Table 2‑1/2‑5 allowed uses matrix and the zoning map (§ 18.06.030; Article 2 tables) .

(If you need a parcel‑specific district, confirm the official zoning map on file in the City Clerk’s office per § 18.06.030) .

Citywide development standards — where the big rules live

The Code separates zone‑specific numbers (Tables 2‑2, 2‑4, 2‑6) from standards that apply to every zone. Key centralized chapters and sample citations:

• Site planning, heights, setbacks, encroachments and corner visibility: Chapter 18.22 (see § 18.22.010 purpose; corner vision triangle 25 ft in § 18.22.020.C; height measurement in § 18.22.030; setbacks rules and encroachments in § 18.22.060) . Link to the city’s consolidated East Palo Alto Development Standards.
• Zone tables (per‑zone FAR, story/height, lot coverage, setbacks): Tables 2‑2 (residential), 2‑4 (mixed‑use), 2‑6 (commercial) in Chapters 18.10, 18.12, 18.14 respectively (examples: MUC 1.75 FAR, MUH 2.5 FAR in § 18.12.030; C‑G up to 3 stories/75 ft in § 18.14.030) .
• Parking and loading rules and exceptions live in Chapter 18.30 (off‑street parking requirements § 18.30.050; exceptions and adjustments in § 18.30.060 and § 18.30.100) — see the city parking page and Chapter 18.30 for the numeric ratios and TDM rules (§ 18.30.050; § 18.30.110) .
• Landscaping, fences, lighting and screening: Chapters 18.26 (fences), 18.28 (landscaping), and § 18.22.040–18.22.050 (equipment screening, lighting) .
• Design and site‑level architectural standards for commercial and mixed‑use zones are embedded in the per‑zone chapters (e.g., § 18.14.040; § 18.12.040) and implemented through site plan and design review (§ 18.86.010) .

For quick reference on the citywide numbers (setbacks/height/FAR/lot coverage/parking) start with the table for the relevant zone (Chapters 18.10/18.12/18.14) and then read the Chapter 18.22 general rules that overlay those tables (§ 18.10.030; § 18.12.030; § 18.22.010) .

Specific plans & overlays

• Ravenswood Specific Plan (RSP) — the Code establishes the RSP Overlay District and incorporates the Ravenswood Specific Plan by reference; the RSP contains its own subdistricts and tailored development rules and design guidelines and therefore governs in the RSP area (§ 18.18.020) . The RSP subdistricts include 4C (4 Corners Gateway), BRC (Bay Road Central), REC (Ravenswood Employment Center), IT (Industrial Transition), WO (Waterfront Office), UR (Urban Residential), UV (University Village), R‑OS (Ravenswood Open Space) and R‑FO (Ravenswood Flex Overlay) — see the RSP chapter and figures for the map and subdistrict definitions (§ 18.18.020; RSP figures) .
• Overlay and combined districts generally are referenced on the zoning map and implemented via overlay chapters or by the specific plan (see § 18.06.030 and § 18.18.010) . Link to the City’s overlay districts page for plan-area context.

---

Building permits & review — the practical permit path

• Determine allowed uses and basic standards: consult the Article 2 use tables for the parcel’s zone (e.g., Tables 2‑1/2‑3/2‑5) and the zone’s development standard table (§ 18.10–18.14) . For a ministerial check that a use and plans meet numeric standards you will request a Zoning Clearance — the City uses Zoning Clearance to verify compliance before issuing building permits (§ 18.84.010; § 18.84.020) .
• Minor/moderate projects: many residential additions and ADUs are approved ministerially (see ADU chapter § 18.96.060 — Director approval within 120 days when objective standards are met) .
• Discretionary review: projects that need discretionary action (Site Plan & Design Review, Conditional Use Permit, Administrative Use Permit, Variance, Planned Development Permit) go through the procedures in Article 7 (Chapters 18.86, 18.88, 18.90, 18.92) with the applicable Review Authority identified in Table 7‑1/7‑2 (§ 18.86.010; § 18.88.040; § 18.90.030; § 18.92.050) .
• Planned Development Permits: can be used to modify many standards for large master‑planned projects (minimum site area requirement applies; Chapter 18.92), but they cannot authorize a land use not allowed by the underlying zone (§ 18.92.020; § 18.92.030) .
• Subdivision & lot‑line work (lot splits, parcel maps, tentative maps, vesting maps) follow Article 5 (Chapters 18.50–18.56) and are required before final lot creation and some major projects (§ 18.50.080; § 18.52.010) .
• Pre‑application (Pre‑App) guidance is required for major projects and recommended for complex projects; it’s the practical first step before full submittal (§ 18.82.030) .

If the project is ministerial and meets Title 18 numeric standards, the Director can issue approvals or a building permit follows Zoning Clearance; if discretionary findings are required the Commission or Council (depending on Table 7‑1) will be involved (§ 18.84.030; § 18.86.050; Table 7‑1) .

State housing law in East Palo Alto

This section summarizes how common California housing laws operate against the City Code.

• Accessory dwelling units (ADUs / JADUs): East Palo Alto has a dedicated ADU chapter 18.96 that implements Government Code requirements while adding local numeric standards: only one ADU per site (§ 18.96.030); lot‑size minimums for attached ADUs (5,500 sq ft) and detached ADUs (7,500 sq ft) and detailed unit‑size caps (attached ADU ≤ 50% of living area up to 1,000 sq ft; detached ADU default 700 sq ft with enlargement rules) — see § 18.96.020–18.96.040 and the ADU permit/ministerial approval rules (§ 18.96.060) . The ADU chapter explicitly provides parking exceptions (no parking required in several state‑defined situations) and ministerial building permit provisions (§ 18.96.040.G; § 18.96.060) . Link to the city’s ADUs page for local process notes.
• Density bonus: the City implements the State density‑bonus rules in Chapter 18.36; the chapter explicitly references Government Code § 65915, describes tiers of incentives (Tier One/Two/Three), and sets process/recordation requirements and the requirement that if a conflict exists, state law controls (§ 18.36.010; § 18.36.050; § 18.36.060) . The Code also explains eligibility rules and the recording of a density bonus housing agreement (§ 18.36.070) .
• SB 9 (ministerial lot splits / duplexes): SB 9‑style ministerial lot splits and duplex objectives are state law; East Palo Alto’s Development Code (2018) does not contain an SB 9‑specific chapter text in the retrieved materials. Verify current local implementation rules with the Planning Department; where state law requires ministerial approval, local code and map constraints (e.g., specific plan overlays, historic districts) may still apply — consult the ADU chapter’s approach to ministerial ADU approvals for a model (§ 18.96.060) and check Chapter 18.06 about zoning map and annexed lands (§ 18.06.030) . (Not found in retrieved materials: an SB 9–specific amendment)
• Local rent control / tenant protections: Title 18 references the City’s Rent Stabilization and Just Cause for Eviction Ordinance in housing/affordable housing contexts (for example, density‑bonus eligibility and demolition/replacement rules reference the City’s Just Cause ordinance) — see Chapter 18.36 (density bonus ineligibility language referencing the City’s Just Cause for Eviction and Rent Stabilization Ordinance) and Chapter 18.48 (demolition/merger rules that reference replacement units or the Rent Stabilization ordinance) (§ 18.36.; § 18.48.) . For the text of rent‑control and eviction protections look to the Municipal Code chapter(s) referenced in those rules (Municipal Code chapters on tenant protections are separate from Title 18) .

California building and safety standards (Title 24) continue to apply at the permit level and are enforced by the Building Division for any construction — see local ADU and building permit references to state building/health/fire codes (e.g., ADU § 18.96.040.E) and start your building permit submittal using the California Building Standards Code as the technical standard referenced in local approvals (§ 18.96.040.E) .

Practical orientation / developer checklist (city‑wide)

1. Confirm parcel zoning on the official map (Chapter 18.06) and read the Table for that zone (Tables 2‑2/2‑4/2‑6) for base FAR/height/setbacks (§ 18.06.030; § 18.10.030; § 18.12.030) .
2. Read the Chapter 18.22 citywide standards (height measurement, setbacks, corner vision triangle 25 ft) that will apply in addition to the zone table (§ 18.22.020; § 18.22.030) .
3. Check for overlay/specific plan rules (Ravenswood RSP) that supersede or refine zone standards in plan area (§ 18.18.020) .
4. For parking and TDM requirements consult Chapter 18.30 early in design (off‑street parking requirements § 18.30.050; adjustment processes § 18.30.100) and the City’s parking page .
5. If you plan residential density increases tied to affordability, use Chapter 18.36 (density bonus) and expect a recorded density bonus housing agreement (§ 18.36.070) .
6. For ADUs use Chapter 18.96 — many ADU submittals are ministerial and the Director must approve within 120 days if objective standards are met (§ 18.96.060) .
7. Submit a Pre‑Application (required for major/complex projects; § 18.82.030) to get early City feedback and identify discretionary triggers (§ 18.82.030) .

Information Gaps / Verify with the City

• Local implementation specifics for SB 9 (ministerial lot splits and duplex approvals) are not present in the retrieved 2018 Title 18 text — local implementing ordinances (if adopted after 2018) or administrative handouts may apply. Not found in retrieved materials: an SB 9–specific local chapter. Verify with Planning staff.
• Current fee schedules, checklists, and any post‑2018 amendments to Title 18 (including code text changes or RSP updates) are maintained separately (Master Fee Schedule; Planning Department handouts). Confirm current fees and any amendments with the Planning Department or City Clerk.
