Pleasant Hill — Development Standards

Last reviewed: July 2, 2026

Overview

This page summarizes the Pleasant Hill Zoning Ordinance (Title 18) rules that control setbacks, height, lot coverage, density, and FAR. It synthesizes the city’s district-by-district development standards table, district-specific rules for accessory structures and ADUs, and citywide measurement and exception rules so applicants can quickly find the decision-relevant limits and the controlling code citations. For procedural topics (permits, building inspections, Title 24 compliance) see the linked pages below; this page stays focused on zoning development standards only.

Key local links used below: see the citywide zoning overview at Pleasant Hill zoning & planning overview and the city’s tables for parking and project review at Pleasant Hill Parking, Pleasant Hill Design Review, Pleasant Hill Overlay Districts, and the ADU rules at Pleasant Hill ADUs. Building-height measurement refers to the California Building Standards Code. For landscaping requirements see Pleasant Hill Landscaping and Screening.

How to read the code here

• The quantitative dimensional standards in the zoning tables are established in § 18.15.030 and the accompanying tables; additional stepback and measurement rules are in § 18.15.040 and § 18.55.030. See Table 18.15-B for the residential table and Table 18.25-B for commercial districts (Development Standards – Commercial, Office and Industrial) .
• Accessory Dwelling Unit (ADU) special rules (setbacks, lot coverage/FAR exemptions) are in § 18.15.050 (ADUs) .
• Minor Exception (small changes to standards), measurement rules, accessory-structure rules, and stepbacks are in § 18.130.020, § 18.55.040/§ 18.55.030, and § 18.15.060 respectively .

Decision‑relevant summary table (quick reference)

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

R-20 (Single‑Family Residential)

• Purpose / typical uses: Intended for low‑density single‑family residential development (implied throughout Title 18 and referenced in the ADU rules) — see § 18.15.030 and the ADU subsection that references R‑20 specifically .
• Key dimensional standards: Max height 35 ft, lot coverage 25%, FAR 0.40 (res), front setback 25 ft (as shown in Table 18.15‑B) § 18.15.030 .
• Where it applies: Applies to parcels mapped as R‑20 on the city zoning map; see the Zoning Map and district list in § 18.05.050 .

R-15, R-10, R-10A, R-7, R-6 (Single‑Family Residential tiers)

• Purpose / typical uses: Progressive step‑down of single‑family densities (R‑15, R‑10 etc.); frequently treated the same for ADU standards § 18.15.050 .
• Key standards (summary): Max height normally 35 ft, lot coverage 25–35% depending on the specific district, front setbacks 20 ft (R‑15/R‑10/R‑7 group) — see Table 18.15‑B § 18.15.030 .
• Where it applies: Standard single‑family neighborhoods across Pleasant Hill; check the zoning map to confirm the base district § 18.05.050 .

RMD (Mangini‑Delu Residential)

• Purpose / typical uses: Special historic neighborhood overlay/district (Mangini‑Delu) — the code lists RMD as its own district; ADU and lot coverage rules mention RMD explicitly § 18.15.050 and Table 18.15‑B § 18.15.030 .
• Key standards: Front setback 15 ft, lot coverage up to 70% (note higher lot coverage), height 35 ft per Table 18.15‑B § 18.15.030 .
• Where it applies: Parcels mapped RMD (Mangini‑Delu) — verify parcel zoning on the city zoning map § 18.05.050 .

Multi‑Family districts (MFL / MFVL / MFM / MFH / MFVH and PUD/PPD)

• Purpose / typical uses: Multi‑family residential at rising intensities (from lower‑rise MFL/MFVL to higher MFH/MFVH); PUD/PPD denote planned developments § 18.15.030 and the multifamily open‑space rules in § 18.15.040 .
• Key standards: Heights generally 35 ft for many MF districts but certain types or denser categories show higher maxima in the city table (up to 75 ft for the densest classifications), lot coverage 40–70%, usable open space minimum 200 sq ft per unit for 3+ units § 18.15.040.G and Table 18.15‑B § 18.15.030 .
• Where it applies: Mapped multi‑family zones — check parcel mapping; hillside multi‑family is subject to the Hillside PUD rules § 18.35.040 .

Mixed‑Use (MX, MX‑N, MX‑HD, MX‑VHD)

• Purpose / typical uses: Mixed residential and commercial development; higher intensity in MX‑HD and MX‑VHD types § 18.15.030 .
• Key standards: The ordinance explicitly notes that for residential uses in mixed‑use zoning districts there is no lot coverage or FAR maximum established in the MX series (important for design) — see the ADU and Table entries § 18.15.030 and § 18.15.050 .
• Where it applies: Core commercial corridors and nodes mapped MX on the zoning map — confirm in § 18.05.050 .

NB / RB / PAO / C / LI (Neighborhood Business, Regional Business, Professional/Administrative Office, Commercial, Light Industrial)

• Purpose / typical uses: Non‑residential commercial, office and light industrial uses with specific development tables; see Table 18.25‑B for the commercial/industrial development standards § 18.25.030 .
• Key standards (typical): Building height ~35 ft, commercial gross floor area ratios 0.35–0.40, front setbacks 10–25 ft depending on district, minimum site landscaping percentages and corner/cumulative setback rules in Table 18.25‑B § 18.25.030 .
• Where it applies: Mapped commercial/industrial parcels; supplemental development standards and accessory use rules are in § 18.25.030 .

REC (Parks & Recreation)

• Purpose / typical uses: Parks, recreation and public facilities — the code lists REC‑type permitted recreational uses and development standards in § 18.45.030 and required permits in § 18.45.040 .
• Key standards: Front setback 20 ft, rear 15 ft, side 5 ft, height 35 ft, lot coverage 30% (Table 18.45‑A) § 18.45.030/§ 18.45.040 .
• Where it applies: City parks, recreation properties and mapped REC areas.

OS (Open Space)

• Purpose / typical uses: Natural open space; the code states there is no fixed density, FAR or standard numeric maxima — development standards are to be established by the Zoning Administrator consistent with the OS purpose § 18.50.030 .
• Key standards: No general numeric density/FAR; setbacks/lot coverage are established on a case‑by‑case basis by the City (ZA) § 18.50.030 .
• Where it applies: Parcels mapped OS.

Citywide rules and important details (applies in all districts)

• Height measurement is taken as provided in the California Building Standards Code and implemented by the city; see § 18.55.030 for which base point and methods apply (and which rooftop features can exceed height by up to 8 ft if accessory) .
• Stepbacks / additional setbacks for portions of buildings above 35 ft: any building portion above 35 ft must step back one foot for each foot above 35 ft; side/rear setbacks are increased by one foot for each foot above 35 ft up to a limit shown in § 18.15.040 (illustrated by Figure 18.15‑1) .
• ADU treatment: ADUs under § 18.15.050 have their own rules — short summary: ADU area up to 800 sq ft has lot coverage and FAR exemptions, side/rear setbacks minimum 4 ft, and ADUs cannot cause the lot to exceed the underlying district’s FAR or lot coverage (except for the stated exemptions) — see § 18.15.050 for full text and procedural rules .
• Accessory structures: Height caps (12 ft flat / 14 ft pitched) and setback rules for sheds/garages are in § 18.15.060; smaller projections under 18 in. may need no setback; accessory rooftop decks are often prohibited on small projects (see ADU/Two‑unit rules) .
• Landscaping / open space: Residential site landscaping percentages and multifamily open space minima (200 sq ft/unit for 3+ units) are in § 18.15.040 and the district table § 18.15.030; landscaping along interior property lines is required in certain multi‑family adjacencies § 18.15.040.I .
• Minor Exceptions / Variances: Minor Exceptions can adjust FAR, lot coverage, setbacks, and other standards within limited percentages; refer to § 18.130.020 for the scope and caps (e.g., FAR +10%, lot coverage +10%, setbacks -20% but never below absolute minima) .

Checklist (what an applicant must satisfy before design/permitting)

• Confirm base zoning district for the parcel (check the Zoning Map; establishment in § 18.05.050) .
• Read the district table (Table 18.15‑B or Table 18.25‑B) for numeric limits: height, lot coverage, FAR, setbacks (§ 18.15.030, § 18.25.030) .
• Confirm measured building height rules and roof/feature exceptions in § 18.55.030 and follow Title 24 methods (see California Building Standards Code) .
• If proposing an ADU, check § 18.15.050 for ADU setbacks, exemptions from lot coverage/FAR, and processing steps (ministerial vs. discretionary) .
• Check stepback requirements for any building portions above 35 ft in § 18.15.040 .
• Confirm parking requirements early and design accordingly (see Pleasant Hill Parking and Chapter 18.80 referenced by the district tables) .
• If requesting relief (Minor Exception or Variance), check caps and findings in § 18.130.020 and Chapter 18.55 for minimum absolute setbacks that cannot be reduced .
• Verify landscaping and open space minimums applicable (see § 18.15.040 and district table) .
• For projects in overlay or special districts (HPUD, RMD, REC, OS) confirm supplemental rules in the relevant chapter (§ 18.35.040, § 18.45.030, § 18.50.030) .

Risks & Ambiguities

Plain‑English summary

Pleasant Hill’s Title 18 sets the numeric limits you need to design a compliant project: each base zoning district (R‑20, R‑15, R‑10, R‑7, the MF classes, MX, NB/RB/C, REC, OS, etc.) has a table listing height, setbacks, lot coverage, and FAR; ADUs and accessory structures have their own special rules and limited exemptions. Always confirm the parcel’s base and any overlays and measure height per the code’s measurement rules; for small deviations use the Minor Exception caps or pursue a Variance. Key controlling sections include § 18.15.030, § 18.15.040, § 18.15.050, § 18.25.030, § 18.55.030, and § 18.130.020 .
