How to Comply with the ECAD Ordinance When You Sell Your Home

The ECAD ordinance applies to homes:

  • Within the Austin Energy service area
  • Within the Austin city limits
  • 10 years old or older

Condominiums with one to four units follow ECAD rules for residential properties. Condominiums with five or more units follow the rules for ECAD multifamily properties

To determine if your property requires an ECAD home energy audit, check your property's ECAD status.

Option 1: Schedule a Home Energy Audit with a Qualified ECAD Energy Professional

The easiest way to comply with the ECAD ordinance is to complete an energy audit with an ECAD Energy Professional early in the selling process. This provides you with plenty of time to schedule and complete the audit.

See if your house or the one you are buying is ECAD compliant.

Use a certified ECAD Energy Professional to conduct the audit. ECAD home energy audits are comprehensive and require specialized equipment. The Energy Professional provides a copy of the energy audit to Austin Energy as well as an Audit Certificate to attach to the Seller’s Disclosure Notice.

  • Energy Professionals set their own rates. The estimated cost of an audit is about $200 to $300 for a typical single-family home 1,800 square feet or smaller with one air conditioning system. Customers may consider getting multiple estimates and checking references.
  • Qualified ECAD Energy Professionals are certified Residential Energy Services Network (RESNET) Raters or Building Performance Institute (BPI) Building Analyst Professionals.

After completing an ECAD home energy audit, you will receive an Audit Certificate to attach to the Seller’s Disclosure Notice. You must provide the energy audit results to prospective buyers:

  • At least three days before the end of the option period or time of contract
  • If no option period exists, at the time of the contract signing

Residential home energy audits meet the energy audit requirement for a period of 10 years after the audit is initially performed.

Option 2: Participate in a Qualifying Austin Energy Program

You can also ensure compliance with the ECAD ordinance by participating in one of the following:

  • Home Energy Savings is a whole-home approach to energy efficiency that offers rebates and low-interest financing to help you make home energy improvements.
  • Weatherization Assistance offers free home energy improvements to qualifying customers for a safer, more comfortable, and more energy efficient home.
  • Rebates and Incentives provide ECAD compliance for customers who 1) complete three or more qualifying energy efficiency improvements or 2) participate in a program that provides at least $500 in rebates for energy upgrades.
