Solar Water Heater Variance
NOTICE: Because of the recent court decision cited below, DBEDT can no longer accept for approval gas demand tankless water heaters as an option for a solar water heater variance until we receive guidance from the Final Order from Hawaii Circuit Court Judge Jeffrey Crabtree in Hawaii Solar Energy Association and Sierra Club v. DBEDT, Civil No. 18-1-1398-09 (JPC), February 5, 2019. Please see the other solar water heater variance options – or – install a solar water heater.

New Solar Water Heater Variance Procedures and Online Application
All new single-family dwellings built in the State of Hawaii are required to have a solar water heater (Hawaii Revised Statutes §196-6.5). If a solar water heater will not be installed, a “variance” (exemption) from this state law must be requested and approved for building plans to be accepted. “Single-family dwelling” includes Accessory Dwelling Units and similar single-family dwellings.

The chart below summarizes all the requests for a variance from the solar water heater mandate processed by DBEDT. It is updated regularly as requests are received and as variances are approved or denied.
All NEW single-family dwellings built in the State of Hawaii are required to have a solar water heater (HRS §196-6.5). A request for a variance from this state law can be submitted to DBEDT if it meets the criteria for variance as attested (and submitted) by an architect or mechanical engineer licensed to do business in the State of Hawaii. As stated in Act 204 (June 26, 2008), the legislation creating HRS §196-6.5, “the purpose of this Act is to increase the use of renewable energy to protect our environment, reduce pollution, make housing more affordable, and enhance Hawaii’s local economy.” HRS §196-6.5 also allows for the creation of administrative rules and the assessment of fees.
Hawaii Administrative Rules, Title 15, Chapter 37, “Solar Water Heater Variance,” was adopted on August 27, 2018. The purpose of this administrative rule is to provide an online application to automate solar water heater variance requests. A response to the variance request will be automatically e-mailed to the submitter when a decision is made. This rule also allows the State to charge a processing fee for each variance request.
A public hearing on the administrative rule was conducted on November 1, 2017, Leiopapa A Kamehameha building, 235 South Beretania Street, Honolulu, Hawaii. Prior notification of the public hearing was publicized in the Honolulu Star-Advertiser, Hawaii Tribune-Herald, West Hawaii Today, The Maui News, and The Garden Island, on September 29, 2017. Also, public notice about the administrative rule and the hearing was posted on this website and at all four county building permit offices prior to the public hearing.
