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

How to Comply with the ECAD Ordinance When Selling Your Home

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, 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.

Homeowners interested in saving money on their utility bills and increasing their homes’ energy efficiency are encouraged to have their homes audited before they consider selling, as early audits can pinpoint simple ways to increase a home’s energy efficiency. Additionally, under the current ordinance, each energy efficiency audit will be good for 10 years, so having your Austin home audited now can prevent a last minute scramble to comply with the ordinance.

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 applies:

  • The home is in foreclosure or pre-foreclosure;
  • Title of the property is transferred from one family member to another without payment;
  • Title is transferred under court order, probate proceedings or dissalution 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 efficiency measures;
  • The home seller participated in the Austin Energy Free Weatherization Program not more than 10 years before the time of sale.

How much will the audit cost?

Energy audits are expected to cost $200 to $300 for an average-size home in Austin with one heating, ventilating and air conditioning (HVAC) unit.

Where can I find an auditor?

ECAD audits must be conducted by professionals who have been certified by either the Residential Energy Services Network (RESNET) or the Building Performance Institute and who are registered by Austin Energy as an approved ECAD auditor. Find a list of certified ECAD auditors at
