Last reviewed: July 2, 2026

Overview

This page summarizes what the Pleasanton Zoning Code (Title 18) says about development standards that control the bulk and placement of buildings — setbacks, heights, separation, lot sizes, lot coverage / floor area limits, and related site standards — and where to look in the code for the full rules. It focuses only on development-standards material in the municipal zoning ordinance (Title 18), not building code, permit process, or tenant/ housing-law topics. For design-review and parking rules referenced here, see the linked local pages.

How to read this page

  • Bolded terms are the code labels you will see in the ordinance (district names and numeric standards).
  • Each rule below is anchored to the Pleasanton Zoning Code section(s) where that topic is discussed and to the retrieved ordinance file. Where a numeric standard or a district-specific table entry was not visible in the retrieved materials, I note that as "Not found in retrieved materials" so you can Verify with the jurisdiction.

Citywide rules (where the ordinance locates the development standards)

  • General purpose and application of Title 18: § 18.04.010 – § 18.04.040 .
  • Yards / setbacks, distances between buildings, corner-lot rules, fences and visibility triangles are handled in Chapter 18.84 (frequently cited as § 18.84.010, § 18.84.090, § 18.84.100, § 18.84.110) .
  • Design review triggers are in § 18.20.010 (design review requirement referenced for additions and some accessory structures) .
  • Driveway / parking dimensions and where parking may be located are in § 18.88.040 (used repeatedly for lot frontage/driveway and parking limits) .
  • Accessory dwelling unit standards (setbacks, ADU heights, FAR applicability) are in Chapter 18.106 (see § 18.106.020 and § 18.106.070) .
  • Nonconforming uses and when structures must be brought into conformity appear in § 18.120.060 and related subsections .

(If you need the zoning schedule with every district’s numeric table, verify with the city; the zoning schedule table itself and some district entries were not fully visible in the retrieved excerpts. Verify with the jurisdiction.)

District-by-district snapshot

Below are the districts that the retrieved ordinance excerpts discuss with the most decision-relevant development standards. Each subsection lists the code references where the topic appears in the retrieved materials and a short practical note.

Note: Where the file excerpts did not include a complete zoning schedule (numeric lot coverage, FAR or all permitted uses for each district), I mark that field "Not found in retrieved materials" and indicate where to look.

R districts (single-family and multi-family residential: R-1-6,500, R-1-7,500, R-1-8,500, R-1-10,000, RM-4,000, RM-2,500, RM-2,000, RM-1,500)

  • Purpose / typical uses: residential; single-family and medium-density multifamily per district. See general Title 18 purpose language in § 18.04.010 – § 18.04.040 .
  • Key dimensional standards:
    • Front-yard depths: The code explicitly recognizes a 20 ft minimum front yard as the established setback for R-1-6,500, R-1-7,500, R-1-8,500, and R-1-10,000 in applicable cases (see Chapter 18.84). See § 18.84.010 and related yard rules in § 18.84.090 and § 18.84.100 .
    • Separation between structures / story separation: Upper-story separation standards for R districts are in § 18.84.100 (two-story vs one-story separation minima: 20 ft between two multi‑story structures; 17 ft where one is single-story) .
    • Accessory structures: Class I/II accessory structures location and coverage limits (e.g., limitations relative to rear yards and property lines) are governed by § 18.84.010 and § 18.84.100; accessory structures over 10 ft in height require design review under § 18.20.010 .
    • Fences, hedges, sight lines: front-yard fence height limits and open/solid fence treatments are in § 18.84.090 (and related subsections) .
  • Lot coverage / FAR / density: Not found in retrieved materials for a per‑district numeric summary. The code repeatedly references district-specific floor‑area-ratio and open space rules but the numeric table(s) with coverage/FAR per district were not visible in the excerpts. Verify with the city zoning schedule (Title 18 zoning table).
  • Where it applies: Citywide residential neighborhoods designated R-1/RM on the zoning map; front-yard averages and block‑front averaging rules are handled in the same Chapter 18.84 provisions .

Practical note: additions that add more than 10 ft of height to a main structure in R districts trigger design review under § 18.20.010 .

(See also ADU-specific rules in Chapter 18.106 for how ADUs interact with these residential standards.)

RM and housing development / urban lot splits (including “housing development units” and urban lot split standards)

  • Purpose / typical uses: multi-family or intensified residential development; rules for urban lot splits and two-unit developments. See ministerial urban-lot-split standards in the housing/unit chapter in Title 18.
  • Key standards (from housing development / urban lot split chapter):
    • Minimum newly-created parcel size: 1,200 sq ft; minimum frontage 30 ft; minimum parcel width 30 ft; minimum depth 40 ft (§ referenced in the urban lot split chapter; see retrieved materials) .
    • Setbacks for housing development units: minimum 4 ft to interior side and rear property lines for housing development units created via urban lot split or two‑unit development (see urban-lot-split/housing development unit chapter; specific subsection references are in the retrieved materials) .
    • Parking for such units: typically one covered off-street parking space per unit unless within defined transit proximity; parking locations are restricted (not in front/side yard, etc.) per § 18.88.040 and the housing chapter .
    • Upper-story floor area cap (for housing development units): upper stories limited to 40% of the first-floor area (housing development standards) .
  • FAR/density: The housing development chapter ties cumulative floor area to the district’s allowed floor area; where necessary to reach a minimum unit size (800 sq ft), some small departures are allowed — see chapter language in the retrieved file (exact base densities per district not included in excerpts) .
  • Where it applies: projects seeking to create two housing units or pursue an urban lot split; see Chapter for ministerial approval criteria and § 18.88.040 for driveway/parking limits .

Accessory Dwelling Units (ADUs) — Chapter 18.106

  • Purpose / typical uses: accessory dwelling units and junior ADUs on residential properties. Details and exceptions for Statewide Exemption ADUs are explicitly referenced in § 18.106.020 and § 18.106.070. The town aligns several ADU standards with state law and also applies local controls where allowed .
  • Key numeric standards explicitly in the ordinance excerpts:
    • Detached ADU height: base maximum 16 ft height (exceptions and higher allowances described for conversions or locations near transit or on lots with multistory multifamily) — see § 18.106.070 .
    • Detached ADU setbacks: minimum 4 ft from side and rear property lines (with exceptions where the ADU occupies the location and dimensions of an existing legal accessory structure) — § 18.106.070 .
    • ADUs must comply with applicable FAR maximums and open-space requirements of the zoning district except where State exemptions apply — see § 18.106.020 and § 18.106.070 .
  • Practical note: the code repeats that ADUs are subject to district floorarea/open-space controls unless the ADU qualifies for a state exemption; the ordinance text in Chapter 18.106 should be consulted closely for how local and state rules interact .
  • For ADU process and allowed deviations, consult the ADU chapter and state ADU laws; see the local ADU page and the California ADU law link below.

Commercial / Office / Industrial districts (C-C, C-S, C-A, C-R, O, I-P, I-G, and PUD variants including Hacienda PUD)

  • Purpose / typical uses: commercial, retail, service, office, and industrial uses as labeled by district. The zoning schedule assigns permitted uses by district (zoning schedule not fully visible in the retrieved excerpts) .
  • Key development standards visible in excerpts:
    • Height caps in select non‑residential districts: the retrieved excerpts refer to allowed heights such as 85 ft for certain parcels in C-R(p) and PUD-C (Johnson Drive Economic Development Zone) and 55 ft for uses in O, I-P, I-G, and certain PUD districts; the code also allows additional height to screen roof‑mounted equipment and provides design/scale requirements for buildings over 40 ft (pedestrian-scale articulation, setbacks for levels above second story adjacent to residential) — these provisions are included in the Title 18 excerpts (see the zoning code excerpt file) .
    • Buildings over 40 ft: require pedestrian‑scale treatment; where adjacent to residential, floors beyond the second level must be stepped/backset as determined by the zoning administrator (see the retrieved excerpts) .
    • Setback increases: when a non-residential site adjoins an R district, the minimum side or rear yard shall be 10 ft greater than the district minimum in many cases (with special larger requirements in I‑G adjacent to R districts) — see Chapter 18.84 rules on interface treatments .
  • Lot coverage / FAR / exact district tables: Not found in retrieved materials for the full set of commercial/industrial districts in the excerpts. Verify with the city zoning schedule and the PUD development plans where applicable.
  • Where it applies: the commercial and industrial districts on the zoning map and any parcel with a PUD overlay (Hacienda PUD and Johnson Drive references appear in the excerpts) .

Practical note: For taller commercial or PUD projects (over 40 ft) expect additional design requirements and possible discretionary review; see the design-review link and the specific PUD development plan language.

Special corridors and Foothill Road provisions

  • The Foothill Road corridor has special lot-size, setback, side-yard and height controls in an adopted ordinance (Ord. 1468) that are codified in the zoning code excerpts: minimum lot size 30,000 sq ft for first-tier lots, a 150 ft setback from Foothill Road edge of pavement, side yard minimums commonly 25 ft (with larger setbacks for wide fronts), and main structure height capped at 30 ft for that corridor (these appear in the Foothill Road district language in the code excerpts) .
  • Where it applies: the first tier of lots along Foothill Road and frontage roads; the code states these special requirements apply only to the first tier and not to lots westerly of the first tier .

Checklist — what an applicant must demonstrate (minimum)

  • Confirm the zoning district for the parcel on the City zoning map and consult the district entry in Title 18 zoning schedule (Verify with the jurisdiction). See the City's zoning page.
  • Confirm required front/side/rear setbacks and corner-lot rules in Chapter 18.84 (e.g., § 18.84.010, § 18.84.090, § 18.84.100) and show them on plans .
  • For ADUs, show compliance with Chapter 18.106 (setbacks, heights, and whether State ADU exemptions apply) .
  • Show parking and driveway compliance per § 18.88.040 and the local parking rules (location and dimensions) and how any transit exceptions apply .
  • If your project adds more than 10 ft of height to an existing building or accessory structures exceed 10 ft in height, plan for design review under § 18.20.010 .
  • If applicable, demonstrate conformance with non‑residential adjacency rules (e.g., added side/rear yard where non‑residential adjoins an R district) in Chapter 18.84 .
  • Show any necessary open-space / floor-area calculations and how ADUs or housing development units will comply with district FAR/open-space maximums (chapter references: housing development chapter and Chapter 18.106) .
  • For special corridors (like Foothill Road) confirm additional corridor standards (lot size, setback, height caps) per the Foothill Road provisions .

Risks & Ambiguities

Issue Why it matters What to verify
Missing numeric district tables (lot coverage, FAR, exact height caps) You need the zoning schedule to compute allowable building area and plan massing; excerpts did not include the full numeric table. Verify the official Title 18 zoning schedule for the parcel; confirm the district’s maximum FAR and lot coverage with City staff.
Some tall‑building allowances (55 ft / 85 ft) appear in excerpts without a clear section header in the excerpts Height allowances determine whether a project will be ministerial or discretionary and whether stepbacks/design review apply. Confirm exact text/location of the height limits in Title 18 (search the full zoning code PDF or eCode360 entry) and whether the parcel is within a PUD or special plan that controls height.
ADU interplay with local FAR and open‑space limits ADUs may be exempt or subject to local FAR depending on state exemptions; misreading leads to incorrect sizing. Read Chapter 18.106 in full and verify whether your ADU is a Statewide Exemption ADU or must meet local FAR/open-space; consult staff for site‑specific interpretation.
Corner-lot/front-yard averaging rules Front‑yard averages on a block can change the required setback; misapplication affects compliance. Locate the block‑front averaging rules in Chapter 18.84 and check the adjacent block frontage improvements; get City determination on average front‑yard calculation.
Where code says “to the satisfaction of the zoning administrator” (e.g., stepbacks or pedestrian scale) These are discretionary standards and can vary by reviewer. Expect to provide design studies and be prepared for design review; verify the review path and submittal materials required.

Plain‑English summary

Pleasanton’s zoning code controls where and how big buildings can be through the yard/setback rules in Chapter 18.84, housing/lot‑split rules (urban lot splits, two‑unit standards), ADU rules in Chapter 18.106 (including 4 ft ADU side/rear setbacks and 16 ft base detached ADU height), and various district-specific rules for height and adjacency; many of the detailed numeric district limits (lot coverage, FAR, exact height tables per district) are in the full zoning schedule in Title 18 and should be checked on a parcel-by‑parcel basis with the city. Key sections to read are Chapter 18.84, Chapter 18.106, § 18.20.010, and § 18.88.040.

Frequently asked questions

What can I build on an R-1 lot in Pleasanton?

Permitted uses and the allowed building bulk are controlled by the R‑1 district standards in Title 18. Basic residential uses are allowed; the R district setbacks, separation and accessory structure rules (e.g., separation distances and accessory structure rules) are in Chapter 18.84 (see § 18.84.010 and § 18.84.100). For precise permitted uses and numeric maximums (FAR, lot coverage) consult the zoning schedule for your parcel and the zoning map — Verify with the jurisdiction.

What are Pleasanton setback requirements for single‑family homes?

Setbacks for single‑family homes are set in Chapter 18.84. The code excerpts recognize a 20 ft front yard for certain R‑1 districts (R‑1‑6,500 / 7,500 / 8,500 / 10,000) and provide side/rear yard, corner‑lot and visibility triangle rules in § 18.84.010, § 18.84.090, and § 18.84.100. For parcel‑specific front/side/rear numbers consult the zoning schedule and Chapter 18.84.

Do I need design review for an addition that raises my house?

Additions that increase the overall height of a main structure or accessory structures above certain thresholds (for example, accessory structures over 10 ft in height or additions exceeding 10 ft in height, per the ordinance excerpts) trigger design review under § 18.20.010. Check Chapter 18.20; the zoning administrator or planning commission may require design review materials.

What are the ADU height and setback limits in Pleasanton?

Local ADU rules in Chapter 18.106 specify a base maximum for detached ADU height of 16 ft, with exceptions (e.g., conversions or transit‑proximate lots), and a 4 ft minimum side/rear setback for detached ADUs (subject to exceptions if the ADU occupies an existing accessory structure footprint). See § 18.106.070 for details.

How does Pleasanton treat floor area ratio (FAR) and lot coverage for ADUs and multiunit housing?

The code states ADUs must comply with applicable FAR maximums and minimum open space requirements established by the zoning district unless the ADU is a Statewide Exemption ADU; the housing development chapter ties cumulative floor area to the residential district allowances. The specific numeric FAR and lot‑coverage maxima per district were not visible in the retrieved excerpts — Verify with the zoning schedule in Title 18 and Chapter 18.106.

What happens if a building is damaged and was nonconforming?

If a nonconforming structure is damaged more than 50%, restoration is limited: the structure must be restored in full conformity with current regulations and the nonconforming use cannot be resumed. The nonconforming rules and removal/alteration schedule are in § 18.120.060 and related subsections.

Are there extra rules for tall commercial buildings in Pleasanton?

Yes — the code excerpts allow multi‑story commercial/PUD heights in certain places (excerpts reference allowances such as 55 ft and 85 ft in some PUD/C‑R locations) but require pedestrian‑scale treatments and stepbacks for levels above the second story adjacent to residential uses; buildings over 40 ft get special facade/mass/landscape requirements. These provisions are discussed in the zoning excerpts; confirm the exact height allowances for a parcel’s district or PUD development plan.

Where do I find driveway and parking placement rules that affect setbacks?

Driveway and parking placement requirements (including driveway widths and limits on parking being located within required front/side yards) are addressed in § 18.88.040 and the housing development unit chapter; check those sections when designing access so you don't locate parking in a required front yard.

If my lot borders a commercial or industrial site, are there extra yard requirements?

Yes — when a non‑residential site adjoins an R district, the code generally requires the minimum side/rear yard to be 10 ft greater than the district minimum (with larger special buffers for some industrial adjacencies). These interface standards are in Chapter 18.84.
