SAN FRANCISCO—One positive in this pivot year is that the energy-efficient home credit codified in Internal Revenue Code Section 45L has been extended from January 1, 2018 to December 31, 2020. The credit provides $1,000 or $2,000 to contractors or developers for newly built or substantially renovated energy-efficient residential dwelling units that are purchased, leased or rented from the contractor and used as a residence.

"The 45L energy-efficient home credit is sometimes overlooked by housing builders and developers, and with the credit set for expiration this year, it should be high on the list of strategies to consider for new or recently completed projects," Jeff Shilling, Portland-based director of Moss Adams' Oregon-Northern California Tangible Assets group, tells GlobeSt.com.

An eligible contractor/developer must meet both of these criteria: have constructed or substantially renovated the energy-efficient residential dwelling unit and own/have a basis in the property during its construction.
