ECAD for Residential Homes

Information for Home Sellers, Buyers, and Real Estate Professionals

The Energy Conservation Audit and Disclosure (ECAD) ordinance, as described in the Austin City Code Chapter 6-7, requires that before the sale of their home, owners of a residential building must disclose a home energy audit if all of the following conditions apply to the property:

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

The ECAD ordinance simply indicates who is responsible for obtaining the energy audit. ECAD does not require that you make improvements.

Homeowners can also proceed with an ECAD audit at any time prior to putting a house on the market.

Energy Audits Reveal Improvement Opportunities

ECAD requires that you work with a certified ECAD Energy Professional to conduct an energy audit of any residential property you want to sell and disclose your home's energy efficiency as part of the real estate transaction. This audit covers:

  • Air conditioning and heating system efficiency
  • Air infiltration, duct performance, air sealing in plumbing, and weatherstripping
  • Windows
  • Attic insulation

Homeowners can use ECAD audit results to make energy efficiency improvements that increase property marketability in a competitive real estate market. ECAD audit results can also serve as an effective tool for advertising existing energy efficiency measures.

Make Sure Your Property is Covered under Residential ECAD

ECAD defines residential properties as:

  • Single family homes (including townhomes)
  • Duplexes
  • Triplexes
  • Fourplexes

If you own a single property of five or more residential units, you must follow ECAD Multifamily rules.


  • Condominiums with one to four units must follow Residential ECAD rules.
  • If you own a condo with five or more units, you follow ECAD Multifamily rules.

Energy Professionals Conduct Energy Audits

A certified ECAD Energy Professional must conduct ECAD audits. ECAD 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 prices. 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.

We recommend that you get at least three estimates and check references.
