Pleasanton ADU Zoning and Building Standards

Thorough knowledge of these standards is important for a smooth construction process and compliance with local law.

Pleasanton ADU Zoning and Building Standards

Property Requirements

Building Size

  • Single Family Zoned Lots

Think classic single-story houses. Your detached ADU can stretch up to 1,200 sq ft, but cozy Junior ADUs (JADUs) capped at 500 sq ft are also an option. Feeling ambitious? The attached ADUs can match the main house size, up to 1,000 sq ft.

  • Duplex Family Zoned Lots

Picture two attached homes sharing a wall. Here, you can build two detached ADUs, each up to 1,200 square feet or up to 25% of the existing main dwelling’s size if you’re going to attach. Plenty of options for family or rental income!

  • Multi-Family Zoned Lots

Apartment buildings and the like. Get creative with up to 2 detached ADUs, each reaching the 1,200 sq ft peak. Attached ADUs can join the party, following the same 1,000 sq ft limit as duplex zones. Remember, JADUs are out of the picture here.


Owner-occupancy is not currently a requirement for permitted ADUs in Pleasanton. From January 2020 to January 2025, a temporary provision in Pleasanton ADU usage offers flexibility for homeowners and investors. They can choose to occupy or rent the unit, pursuing their desired options. This flexibility opens up exciting possibilities for increasing housing availability and generating rental income within the city.

Number of Units Allowed

Most Pleasanton properties allow one detached ADU, with single-family lots additionally eligible for a Junior ADU within the main house. Depending on existing structures, multi-family and duplex zones may permit up to two detached ADUs or conversions, adding 25% more living units.

Pleasanton Building Height

  • Single-Family: Enjoy the freedom to build spacious ADUs up to 16 feet tall, perfect for lofted ceilings or comfortable second-story spaces. Think airy studios or cozy two-bedroom units with plenty of headroom.
  • Duplex Family: Whether you opt for two detached ADUs (up to 16 feet each) or one attached unit following the main dwelling’s height, you’ll have the flexibility to design comfortable living spaces that blend seamlessly with the existing structures.
  • Multi-Family: Here, your ADU options soar! Build up to two detached ADUs, each reaching 16 feet, or convert non-living space into smaller units while maintaining a maximum height of 13 feet. This allows for additional living quarters without compromising the overall scale of the multi-family building.

Pleasanton Building Size

  • Single-Family: The detached ADU can reach 1,200 square feet, ideal for a studio apartment, a one-bedroom haven, or a cozy two-bedroom retreat. Imagine a home office with a nap nook, a guest suite for loved ones, or a rental unit for extra income.
  • Duplex Family: Your duplex ADU shares a wall with its twin but still offers ample square footage. Each detached unit can reach 1,200 square feet, providing independent living spaces. Alternatively, if you prefer an attached unit, its size can match up to 25% of the existing main dwelling’s footprint. Ideal for multi-generational living or creating a dedicated rental space.
  • Multi-Family: You can build two detached ADUs, each with up to 1,200 square feet. Alternatively, converting non-living spaces into smaller ADUs is an option, adding up to 25% more living space to the property and seamlessly blending into the multi-family atmosphere.

Fire Safety Regulations

Regarding fire safety in Pleasanton ADUs, the rules are straightforward: smoke detectors and carbon monoxide alarms are mandatory in all units, ensuring early warning for occupants. Additionally, fire sprinkler systems are not required in ADUs unless they’re also compulsory for the main dwelling, simplifying the construction process while prioritizing resident safety. Remember, adhering to these regulations is crucial for protecting lives and property.


Parking for Pleasanton ADUs isn’t a one-size-fits-all rule! Generally, conversion and junior ADUs require no dedicated parking, while detached and attached units typically need one space. However, exemptions exist for proximity to public transit, historic districts, and car-sharing options.

Utility Connections

New Pleasanton ADUs typically require separate electricity, water, and gas utility meters, ensuring independent usage and billing. However, conversions and junior ADUs sharing existing meters with the main dwelling are permitted under specific circumstances.


Pleasanton ADUs need to breathe! Detached and new construction units must maintain a minimum 4-foot setback from side and rear property lines, ensuring neighborly space and fire safety. Conversions and junior ADUs often have more flexible requirements but always check specific regulations to avoid building hiccups.

Zoning Regulations

Single Family

Pleasanton focuses on spacious, detached homes on larger lots with minimum lot sizes of around 7,500 square feet. This allows for comfortable living with ample space between neighbors, creating quiet, low-density residential neighborhoods prioritizing family and individual properties.

Duplex Family

Shows side-by-side twin homes with a shared wall, usually on slightly smaller lots than single-family zones. With minimums of 5,000 square feet, they optimize land use while ensuring comfortable living spaces for two families. These zones foster friendly, community-oriented neighborhoods with much more density than single-family areas.
