City of Austin Energy Conservation Audit & Disclosure (ECAD) Ordinance

How the ECAD Ordinance Affects Real Estate Transactions

The City of Austin’s Energy Conservation Audit and Disclosure (ECAD) Ordinance became effective June 1, 2009. Here’s what you need to know:

What is required?

Under the ECAD Ordinance, an energy audit is required as part of the Seller’s Disclosure Notice. Home sellers are required to obtain an ECAD audit and disclose the audit results to potential buyers no later than 3 days prior to the end of the option period if all of the following conditions apply:

  • The home is 10 years old or older;
  • The home is within the Austin City Limits; and
  • The home is serviced by Austin Energy.

What if there is no option period in the sales contract?

If there is no option period, audit results must be disclosed prior to execution of the sales contract.

What is an ECAD audit?

The ECAD audit is a specialized energy audit that examines four primary areas in a home: (1) Heating and cooling system (HVAC) efficiency; (2) Air infiltration: duct performance, air sealing in plumbing areas and weather stripping; (3) Windows: shading, low “E” glass and solar screens; (4) Attic insulation.

Are there any exemptions?

Yes. Home sellers are not subject to the requirements of the ECAD Ordinance if any of the following conditions apply:

  • The home is in foreclosure or pre-foreclosure;
  • Title of the property is transferred from one family member to another without payment;
  • Title is tranferred under court order, probate proceedings or dissolution of marriage;
  • The home seller participated in Austin Energy Rebate Programs within 10 years of the time of sale and
    • Received $500 or more in rebates, or
    • Performed three energy efficient measures;
  • The home seller participated in the Austin Energy Free Weatherization Program not more than 10 years before the time of sale.
