San Pablo — Landscaping and Screening
Landscaping and Screening under the San Pablo local zoning and planning code, with the controlling citations.
Last reviewed: July 2, 2026
Overview
San Pablo’s zoning ordinance (Title 17) treats landscaping and screening as two related but distinct regulatory topics: (1) site landscaping, water-efficient planting, tree protection, and stormwater-oriented measures under Chapter 17.48, Landscaping, and (2) fences, walls, gates and screening of service areas, trash, utilities, and parking under Chapter 17.45, Fences, Walls, Gates, and Screening. Both chapters tie into the city’s district development standards (setbacks, open space, and buffering) and the city’s design review process; applicants should also coordinate with San Pablo Parking and the city’s San Pablo Development Standards when preparing plans. See § 17.48.040 and § 17.45.010 for applicability and purpose .
How the rules are organized (quick orientation)
- Landscaping: mandatory landscape plans, water-efficiency and irrigation requirements, tree protection and replacement schedules, post‑installation maintenance and irrigation audits; applies to most new private and public development projects and many residential projects (see § 17.48.040) .
- Screening & fences/walls: measurement rules, different height/transparency limits for residential vs nonresidential contexts, special masonry wall buffer requirements where commercial/industrial uses abut residences, and screening standards for refuse, outdoor storage, utilities, and rooftop equipment (see § 17.45.030–040 and § 17.45.080) .
- Tree protection and replacement: a required tree evaluation for protected trees, thresholds for administrative approval vs design review to remove trees, and minimum replacement sizes in Table 17.48‑B (§ 17.48.120 and Table 17.48‑B) .
District-by-district (how landscaping & screening are applied)
Note: the city’s base districts are identified in Table 17‑26‑A; common base zones are R-1, R-2, R-3, R-4, RMU, NC, CR, CMU, IMU, I, and OS. See Table 17‑26‑A § 17.26. (Use the zoning map to confirm the parcel’s district.)
R-1 — Single‑Family Residential
- Purpose & typical uses: low‑density single‑family homes; accessory uses such as small gardens and ADUs are expressly allowed. See § 17.32.010 and Table 17.32‑A.
- Landscaping: front-yard permeable-surface rules and mandatory landscaping for ground-level open space where new projects occur; small single‑family projects may still trigger Chapter 17.48 if they require building permits (see § 17.48.040) .
- Fences & screening: residential fence limits — front yard 3 ft, rear/interior side 6 ft, corner vision triangle 3 ft (max); lattice and higher fences in rear yards allowed with administrative approval up to 8 ft total in limited locations (see Table 17.45‑A and § 17.45.040) .
- Practical note: front‑yard landscaping must remain permeable (no parking) for R‑1 front yards (§ 17.32.050/E) — check setbacks and permeable-surface rules with the planning staff.
R-2 — Two‑Family Residential
- Purpose & typical uses: duplexes, small multifamily, accessory dwelling units allowed; landscaping required for open space and multifamily projects (see § 17.32.020 and § 17.48.050) .
- Setbacks/open space: R‑2 open space and deck rules interact with required landscaping. If projects create new units or large additions, full Chapter 17.48 landscape-plan submittal is commonly required.
R-3 / R-4 — Multifamily and High‑Density Residential
- Purpose & typical uses: multifamily buildings; landscaping expectations are higher for ground-level private/common open space and screening between multifamily projects and adjacent uses (§ 17.32.070 and § 17.48.050) .
- Fences & screening: when a multifamily or commercial project sits next to a residential parcel, attractive screening/walls plus a minimum 5‑ft planting strip adjacent to the screening with trees at a maximum spacing of 20 ft on center is required (§ 17.45.080/D) .
- Tree protection and replacement rules apply; removing 3+ protected trees requires administrative review or minor design review depending on the number removed (§ 17.48.120) .
NC / CR / CMU / IMU — Commercial & Mixed‑Use Districts
- Purpose & typical uses: retail, mixed‑use, commercial services; Chapter 17.48 applies to commercial site landscaping and parking lot planting as part of development approvals (§ 17.48.040 & design guidelines references) .
- Screening: where commercial or industrial uses abut residences, a 6‑ft masonry screen wall (finished both sides) is required; parking/service area screens have strict design/transparency rules in § 17.45.080 and Table 17.45‑B (§ 17.45.080/C and § 17.45.040) .
- Parking lot landscaping: tree species and spacing guidelines are referenced in the commercial design guidelines and cross‑referenced in Chapter 17.48; consult the commercial guidelines for permitted tree lists and recommended canopy heights to avoid fruit/sap issues for parked cars (§ 17.34 design guidelines and § 17.48.150) .
I / OS / Public & Institutional Districts
- Landscaping and tree protection provisions in Chapter 17.48 apply to public agency projects and institutional development (§ 17.48.040/A.1) . Screening standards for utilities, rooftop equipment and refuse are stated in § 17.45.080 and must be integrated architecturally with primary structures (§ 17.45.080/B,E) .
Overlay districts (D1/D2/D3/MF/CP)
- Overlay districts can add location‑specific landscape or buffer requirements (for example hillside or creek protections); consult San Pablo Overlay Districts and the overlay sections in Title 17 (Chapter 17.38) for added obligations (§ 17.38.010 and Table 17.26‑B) .

Checklist (what an applicant must satisfy for landscaping & screening)
- Determine base zoning (e.g., R‑1, R‑3, CR) and any overlay district on the parcel (Table 17‑26‑A) and confirm applicable zone rules (§ 17.26/Table 17‑26‑A) .
- If new development/rehabilitation triggers Chapter 17.48, prepare a full landscape plan and irrigation plan per § 17.48.050–070; include water‑efficiency calculations and post‑installation scheduling (§ 17.48.050–090) .
- If removing trees, include a tree evaluation and replacement calculations; if removing 1–3 protected trees plan for zoning administrator approval, 4+ trees may require minor design review (§ 17.48.120) .
- For all trash, recycling, outdoor storage, and utility equipment show screening details (masonry enclosure, gate, materials) per § 17.45.080/B–C and Chapter 17.58 for refuse enclosures .
- For commercial/industrial projects adjacent to residential parcels provide 6‑ft masonry wall and 5‑ft planting strip with tree spacing ≤ 20 ft (§ 17.45.080/D) .
- Dimension fences/walls per Table 17.45‑A (residential) or Table 17.45‑B (nonresidential); obtain administrative permit if required for front yard or corner side yard fences (§ 17.45.040) .
- Obtain zoning clearance and any required minor or major design review before construction (see § 17.18.090 and § 17.20.030) — screening/walls in commercial/industrial and many fences in multifamily projects are subject to design review (§ 17.18.090) .
- For rooftop green roofs or rooftop equipment screening, verify building code/structural compliance and coordinate with the California Building Standards Code. (Verify with building department.)
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| Does Chapter 17.48 apply to small single‑family additions? | Applicability language lists specific triggers and exemptions; failing to submit required plans risks stop‑work or remodel rework (§ 17.48.040) | Confirm whether the specific project (e.g., small addition, detached ADU) triggers landscape plan submittal with planning/zoning staff (§ 17.48.040) |
| Front‑yard fence heights for commercial properties | Front yard/corner side yard fences in commercial/industrial zones have admin‑permit requirements and transparency rules (50%–90%) — misunderstanding leads to enforcement or rework (§ 17.45.040) | Verify if an administrative permit is required for front/corner side yard fences and whether high transparency is acceptable (§ 17.45.040/Table 17.45‑B) |
| Tree removal thresholds vs discretionary review | Thresholds (e.g., 3 vs 4+ trees) change the review path from admin to minor design review and can delay projects (§ 17.48.120) | Confirm the protected‑tree list, tree diameters measured at 5 ft, and whether trees lie in the public right‑of‑way; ask for a zoning administrator pre‑check (§ 17.48.120) |
| Exact screening height for unusual outdoor storage | Code requires 6 ft masonry enclosures for outdoor storage but allows higher walls with planning commission approval (§ 17.45.080/C) | If storage items are unusually tall or visible, verify whether the planning commission will require an 8‑ft wall or other mitigation (§ 17.45.080/C) |
| Interaction with stormwater rules (C.3) and BMPs | Landscape choices affect stormwater compliance and may trigger Regional Water Board coordination (§ 17.48.140) | Coordinate with public works/Regional Water Board early; use bioretention and permeable paving guidance in § 17.48.140 and Chapter 8.40 |
Plain‑English summary
If you are building or changing landscaping, fences, or screening in San Pablo, expect to provide a landscape and irrigation plan, follow water‑efficient and stormwater‑friendly rules, protect and/or replace regulated trees, and build fences, walls, and screens to the heights and materials the zoning code requires — commercial projects next to homes usually need a 6‑ft masonry wall plus a planting strip; residential front fences are limited to 3 ft and rear fences generally 6 ft. Key rules live in Chapter 17.48 (landscaping) and Chapter 17.45 (fences/screening) — confirm requirements with planning staff before permitting. §§ 17.48.040; 17.45.040; 17.45.080

Frequently asked questions
What can I build on an R‑1 lot in San Pablo?
Most single‑family detached homes and typical accessory uses are allowed in the R‑1 district; accessory dwelling units are allowed as well. Use regulations and intent for residential districts are in Chapter 17.32 and the district use tables; see § 17.32.020 and Table 17.32‑A for permitted uses and § 17.32.050 for R‑1 specifics .
What are San Pablo’s fence height rules for a typical single‑family property?
Residential fences are limited by Table 17.45‑A: Front yard 3 ft, rear/interior side 6 ft, corner side 6 ft with the vision triangle limited to 3 ft; lattice details and limited 8‑ft exceptions exist by administrative approval (§ 17.45.040 and Table 17.45‑A) .
Do I need to screen dumpsters and trash enclosures?
Yes. Trash, recycling, outdoor storage and utility/service equipment must be enclosed or screened using suitable materials and architecturally integrated designs; outdoor storage enclosures are typically 6 ft solid and must comply with Chapter 17.58 for refuse enclosures (§ 17.45.080) .
Do landscaping rules apply to small residential additions or only to big projects?
Chapter 17.48 applies to many categories of development requiring building permits, administrative use permits, conditional use permits, or design review; it explicitly covers new single‑family and two‑family residences and additions over certain sizes — verify applicability for your specific project with planning staff (§ 17.48.040) .
Are trees protected, and what replacement is required if I remove a tree?
Protected trees require a tree evaluation and protection; removal of three or fewer trees requires the zoning administrator’s approval, removal of four or more trees generally requires minor design review, and replacement standards are in Table 17.48‑B (e.g., 6”+ → 36‑inch box replacement) (§ 17.48.120 and Table 17.48‑B) .
Does a commercial project need a masonry wall where it touches houses?
Yes — when a commercial or industrial project is adjacent to a residential parcel, the code requires a 6‑ft residential masonry screen wall finished both sides and planted on the project side; see § 17.45.080/C and § 17.45.080/D for the planting strip and tree spacing requirement (5‑ft planting strip, trees max 20 ft on center) .
Do I need a landscape and irrigation plan, and is there a post‑installation requirement?
If Chapter 17.48 applies, applicants must submit a landscape design and irrigation plan that meets the city’s water‑efficiency standards; there are also post‑installation certificates and irrigation audit/report requirements (§ 17.48.050–090) .
Will fences or screening require design review?
Certain fences, walls, and screening in commercial, industrial, or multifamily projects are subject to minor design review; the zoning administrator handles minor design review and may refer matters to the planning commission (§ 17.18.090). Also see Chapter 17.45 approvals and administrative permit triggers (§ 17.45.020 and § 17.45.040) .
How do landscaping rules interact with stormwater rules?
Chapter 17.48 integrates sustainable stormwater management (bioretention, biofiltration, permeable paving, etc.) and references coordination with Chapter 8.40 and the Regional Water Quality Control Board for larger projects (§ 17.48.140) .
If I want an ADU, do landscaping or fence rules change?
Accessory dwelling units are allowed in many districts, but landscaping and fence rules apply depending on the scope of the ADU project (new construction vs conversion); check the ADU rules in § 17.60.070 and Chapter 17.48 applicability to see if a full landscape plan is required. Verify with planning for parcel‑specific requirements (ADU cross‑references in the residential use tables) .
