BESO Energy Assessments at Time of Listing

Before listing your building for sale, you must hire a qualified assessor to complete an energy assessment and report, and provide it to the City and prospective buyers. Alternatively, sellers may defer the BESO assessment requirement to the buyer.

Property owners are required to comply with the Building Emissions Saving Ordinance (BESO) requirements before listing their building for sale. Follow the steps listed below to comply with BESO.

Step one: Check building status in the BESO portal

Search for your building’s address in the BESO portal to check its status. Before listing for sale, your building status must be either:

  • “Compliant”
  • “Exempt”
  • “Pending - Deferral to Buyer Requested”

If there is no status listed, or the status is “Due Prior to Listing,” “Pending,” or “ Non-compliant,” continue to step two to bring your building into compliance.

Step two: Bring building into compliance before listing for sale

If your building is not listed as compliant in the BESO portal, then choose one of the below options for bringing your building into compliance.

Option one: Complete an energy assessment

Hire a registered BESO assessor from the relevant category:

  • Commercial, Multi-family & mixed use
  • 1-4 unit residential

Option two: Complete an energy efficiency or electrification upgrade

Complete improvements to make your building more efficient. Choose one of the projects below:

  • Complete a qualifying BayREN Home+ measure (Heat Pump Water Heater Installation or Heat Pump HVAC Installation ) or package (Induction Stove + Heat Pump Dryer + Smart Thermostat, or Attic and Wall Insulation + Air Sealing).
  • Complete a verified comprehensive energy improvement project with a minimum 10% energy improvement, such as the Bay Area Multifamily Building Enhancement Program.
  • Complete a project that transitions a building’s water and/or space heating from natural gas to an electric heat pump.

Option three: Apply to defer the requirements to the buyer

Apply to transfer responsibility for the BESO assessment from the seller to the buyer. The buyer will need to complete an assessment within 6 months.

  1. Complete the online BESO application, selecting “Request deferral to buyer” for the application type. Fill in all fuel source information for the building’s major appliances.
  2. You will receive a link to the Fuel Source Disclosure form, which you must share with all potential buyers.
  3. Once a buyer and sale date are established, the buyer must submit an online application to accept the BESO deferral. The buyer will need to complete the BESO assessment within 6 months or complete one of the upgrades listed in option two.

Option four: Defer for new construction or extensive renovation

Apply to defer BESO assessment requirements for up to ten years.

  1. Complete an online BESO application, selecting “Other deferral (form D)” for the application type. Upload all related permits as attachments to your application.
  2. Submit the Deferral form D to the title company at closing.

Option five: Apply for exemption

Your building is eligible for exemption if it meets the criteria below:

  • Building size is under 850 ft2 or greater than 25,000 ft2
  • Unit is within a larger building (such as an attached condo)

For other deferrals, such as hardship, please contact the BESO team directly at BESO@cityofberkeley.info.

Step three: Submit application and filing fee

Complete the online BESO application and pay a filing fee (if applicable). A BESO form or confirmation email will be sent to the applicant upon approval. Please submit the BESO Form (A, C, D or E) along with the BESO Assessment (if applicable) to the title company at closing.

If needed, you can complete a paper BESO application and write a check for filing fees, made payable to City of Berkeley. Mail the application and filing fee to:
