Pleasant Hill — Zoning

Last reviewed: July 2, 2026

Overview

This page explains how Pleasant Hill's local zoning ordinance (Title 18) organizes land into base and overlay districts, what the common districts mean on the ground, and the most important numeric standards that control what you can build. For procedure and project review you will frequently need to consult the city's development standards and design-review rules; check parking requirements early in a project and confirm ADU rules when thinking about accessory units. See the Zoning Ordinance for the official map and code text: the ordinance establishes base and overlay districts and requires the Zoning Map to show them § 18.05.050 .

Part 2 of the ordinance contains the district regulations and tables of development standards; Part 3 contains citywide standards that apply in every district (for example height measuring rules) § 18.05.030, § 18.55.010 .

I link the first mentions of related topics you will need: development standards, parking, design review, overlay districts, ADUs, nonconforming uses, and the California Building Standards Code.

How the ordinance is organized (quick)

• The ordinance is Title 18 and is titled the “Zoning Ordinance”; the City Clerk keeps the official ordinance and the Zoning Map § 18.05.010 .
• Every lot has a base zoning district; some areas also have overlay zoning districts that supplement or supersede the base rules § 18.05.050 .
• Where the map is unclear, the ordinance provides rules for interpreting boundaries and gives the Zoning Administrator authority to determine exact lines; those determinations are recorded § 18.10.040 .

District-by-district breakdown

Below are the primary zoning districts created by the City (taken from Table 18.05‑A and the district chapters). Each subsection gives the district purpose, typical permitted uses (summary), key dimensional controls you will encounter, and where that district is established in the ordinance. All listings reference the controlling code sections.

R-20 (Single-Family Residential)

• Purpose: Preserve low-density single-family neighborhoods and implement the General Plan Single‑Family Low‑Density land use § 18.05.050, § 18.15.010 .
• Typical permitted uses: Detached single-family homes and accessory residential uses listed in Table 18.15‑A (see residential land use table) § 18.15.020 .
• Key dimensional standards: Front setback: 25 ft; Max lot coverage for ADU calculation: 25% (residential lot coverage standards apply) § 18.15.050 .
• Where it applies / reference: See Table 18.15‑B and Chapter 18.15 for full development standards § 18.15.030 .

R-15 (Single-Family Residential)

• Purpose & uses: Moderate low-density single-family housing consistent with General Plan § 18.15.010 .
• Key dimensional standards: Front setback: 20 ft; Max lot coverage (ADU-related): 25% § 18.15.050, § 18.15.030 .

R-10 / R-10A (Single-Family Residential)

• Purpose & uses: Medium-density single-family lots; R-10A includes an average-lot-size rule (average lot size ≥ 10,000 sf; individual lots may be as small as 7,000 sf) § 18.15.030 .
• Key dimensional standards: Front setback: 20 ft (R‑10A average lot rule noted) ; Max lot coverage (ADU‑calculation): R‑10 = 30% / R‑10A = 35% where indicated § 18.15.050, § 18.15.030 .

R-7 and R-6 (Single-Family Residential, higher density)

• Purpose & uses: Higher-density single-family areas; preserve neighborhood character while allowing smaller lots § 18.15.010 .
• Key dimensional standards: Front setback: 20 ft; Max lot coverage (ADU-related, typical): 35% § 18.15.050 .

RMD (Mangini‑Delu Residential)

• Purpose & uses: Site-specific residential district requiring a comprehensive, site‑wide master plan for development § 18.15.020(E) .
• Key dimensional standards: Front setback: 15 ft; Max lot coverage: 70% (special district value) — development must follow the approved master plan § 18.15.050, § 18.15.030 .

MFVL, MFL, MFM, MFH, MFVH (Multiple-Family Residential tiers)

• Purpose & uses: Range of multi‑family densities from low to very high; allowed multi‑family residential uses are in Table 18.15‑A § 18.15.020, § 18.15.030 .
• Key dimensional standards (high-level): Front setbacks typically 10–15 ft depending on subzone; Lot coverage and FAR increase with density class (examples: MFM/MFH higher lot coverage compared to single‑family; ADU rules adjust open‑space requirements) — consult Table 18.15‑B for precise values § 18.15.050, § 18.15.030 .

MX‑N, MX, MX‑HD, MX‑VHD (Mixed‑Use districts)

• Purpose & uses: Allow mixed residential and commercial uses at different intensities; residential uses in these districts may not have a specific lot coverage or FAR maximum for residential uses (mixed‑use districts are treated differently) § 18.05.050, § 18.15.050 .
• Key dimensional standards: Front setbacks vary: MX‑VHD can be as low as 5 ft; MX‑HD = 10 ft; MX & MX‑N = 15 ft (affects street‑facing design) § 18.15.050 .

NB (Neighborhood Business), RB (Retail Business), PAO (Professional & Administrative Office), C (General Commercial)

• Purpose & uses: Commercial and office land uses supporting neighborhood or citywide commerce; permitted uses and accessory standards are in Table 18.25‑B and Table 18.25‑A § 18.25.030 .
• Key dimensional standards: Typical building height: 35 ft, FAR (commercial): 0.35–0.40 depending on district, front setbacks: commonly 10–25 ft depending on district (see Table 18.25‑B) § 18.25.030, § 18.25.040 .

LI (Limited Industrial)

• Purpose & uses: Light industrial and compatible uses; supplemental development standards for industrial uses are in Sections 18.25.050–18.25.160 § 18.25.030, § 18.25.050 .
• Key dimensional standards: Lot area and setbacks are larger (example lot area 20,000 sf in table) and building heights typically shown at 35 ft in the commercial/industrial table § 18.25.030 .

PUD / PPD (Planned Unit Development / Precise Plan District)

• Purpose: Allow site‑specific, potentially mixed development at custom standards; development must be consistent with the approved PUD/PPD Concept Plan or Specific Plan § 18.30.060, § 18.30.080 .
• Typical permitted uses & standards: As established in the approved PUD or Specific Plan; deviations from underlying zoning are permitted if justified and approved through the PUD process § 18.30.060 .

HPUD (Hillside Planned Unit Development)

• Purpose & uses: Special PUD for hillside sites to protect hillsides and require design and performance standards that respond to slope and views § 18.35.010 .
• Key standards: HPUD applies to sites with average slope ≥ 15%; additional hillside development and design standards apply § 18.35.020, § 18.35.040 .

OS (Open Space) and REC (Parks & Recreation)

• Purpose & uses: Conservation, habitat protection, parks, and recreation lands; generally minimal development allowed except expressly permitted activities § 18.50.010, § 18.45.040 .
• Key standards: The OS chapter lists allowed activities and notes that most development is not permitted unless expressly allowed § 18.50.020 .

Overlay districts: H (Historic) and CR (Cultural Resource)

• Purpose & uses: Apply supplemental rules to protect historic and cultural resources; overlay provisions supplement the underlying base zone and override where in conflict § 18.40.010, § 18.40.020, § 18.05.050(C) .
• Where shown on map: Overlays are noted on the Zoning Map and apply in addition to base zones § 18.30.080 .

Quick reference table — most decision‑relevant standards

Note: Many numeric details (exact lot width, minimum lot area, aggregate side setbacks, scenic route setbacks and site landscaping %) appear in Table 18.15‑B and Table 18.25‑B. Consult those tables in Chapter 18.15 (residential) and 18.25 (commercial/industrial) for parcel‑level numbers § 18.15.030, § 18.25.030 .

Practical guidance / plain‑English interpretation (synthesis)

• Confirm the base zone on the city’s official Zoning Map first: every lot has a base zone and may also carry overlays; the map controls what standards apply § 18.05.050, § 18.10.040 .
• Most residential districts set modest front setbacks (20 ft is common) and cap lot coverage in the 25–35% range for single‑family zones; multi‑family and special districts may allow much higher lot coverage § 18.15.050, § 18.15.030 .
• Mixed‑use zones often remove strict residential lot‑coverage caps and instead manage intensity through other standards (so you cannot assume a uniform FAR across mixed‑use parcels) § 18.15.050 .
• If you need a zoning change, PUD, or Specific Plan, expect a multi‑step discretionary review that includes Architectural Review and Planning Commission recommendation with final City Council action § 18.30.060 .

Checklist (what an applicant must satisfy)

• Confirm the lot’s base zoning district and any overlay designation on the official Zoning Map § 18.05.050 .
• Determine whether the proposed use is listed as permitted ("P") or conditional in Table 18.15‑A / 18.25‑A; if "P" obtain a Zoning Permit first § 18.15.020 .
• Verify dimensional compliance with Table 18.15‑B or 18.25‑B (setbacks, lot area, lot coverage, height) § 18.15.030, § 18.25.030 .
• Check ADU-specific rules (size, setbacks, FAR and lot coverage interactions) before designing an ADU § 18.15.050 .
• Confirm off‑street parking and loading requirements early (parking standards apply citywide and are found in the ordinance) § 18.25.030, § 18.80.* (see parking chapter) .
• If discretionary review is required (Use Permit, Development Plan, PUD), prepare for Architectural Review and public hearings § 18.30.060, § 18.30.070 .
• Where boundaries are ambiguous, get a Zoning Administrator interpretation and record of interpretation § 18.10.040 .
• Coordinate with other city chapters (creek setbacks, tree preservation, signs, etc.)—the ordinance lists cross‑references in each district chapter § 18.15.030, § 18.25.030 .

Risks & Ambiguities

Plain-English Summary

Pleasant Hill divides the city into specific base zones (like R‑20, R‑10, MX, C, LI, etc.) plus overlays (Historic H, Cultural CR, etc.) listed in Title 18. Most single‑family zones have 20–25 ft front setbacks and modest lot‑coverage limits; commercial zones typically limit building height to about 35 ft and set a commercial FAR around 0.35–0.40. Always check the official Zoning Map and the applicable tables (Chapters 18.15 and 18.25) because overlays, PUDs, and site‑specific plans can change the numbers § 18.05.050, § 18.15.030, § 18.25.030 .
