Maximizing Green Building Tax Incentives for Multifamily Developers and Homebuilders

Green building tax incentives: As the world prioritizes sustainability, green building practices have become increasingly important for developers and builders. 

With the environmental benefits, there are also many financial incentives for those who incorporate green building practices into their projects. 

The Inflation Reduction Act (IRA) offers several federal tax incentives for green building, including the 45L Tax Credit, 179D Tax Deduction, and 25C Tax Credit.  

Let’s explore these tax incentives and discuss how multifamily developers and homebuilders can maximize their benefits.

The 45L Tax Credit – Green Building Tax Incentive

The 45L Energy-Efficient Home Tax Credit offers contractors and builders a way to offset the expenses of constructing energy-efficient single-family or multifamily properties. 

45L provides a dollar-for-dollar reduction in their taxes owed or paid during the tax year when the property is sold or leased.

The Internal Revenue Code (IRC) Section 45L offers a credit per dwelling unit for every newly constructed energy-efficient home. 

This credit applies to homes built by eligible contractors and acquired by individuals for residential use within the tax year. It can be transferred to the homeowner and utilized on an amended tax return or carried forward for a maximum of 20 years.

The 179D Tax Deduction – Green Building Tax Incentive

Section 179D is a tax credit provided by the federal government. It allows commercial building owners and primary designers of public building projects to be eligible for a deduction if they include specific sustainable building components in their projects.

The EPAct 179D tax deduction, also known as the Energy Policy Act, offers a sliding scale deduction ranging from $2.50 to $5.00 per square foot. 

This deduction applies to the implementation of energy systems that can reduce energy and power costs by 25% to 50% compared to buildings that meet the minimum requirements set by ASHRAE Standard 90.1-2019. 

To qualify for this deduction, retrofits must demonstrate an improvement of 25% to 50% in terms of existing building performance (EUI).

To understand the eligibility criteria and how to take advantage of the 179D Tax Deduction for multifamily buildings, we recommend reading our comprehensive guide: Your Essential Guide to the 179D Tax Deduction.

The 25C Tax Credit – Green Building Tax Incentive

For homeowners who want to improve the energy efficiency of their homes, the 25C Tax Credit is a highly beneficial incentive. 25C provides individuals with substantial financial savings by reducing their tax bill if they invest in energy-efficient upgrades.

Updated under the Inflation Reduction Act, 25C is a non-refundable credit that aims to promote energy efficiency. It helps homeowners lessen their tax burden by installing qualifying upgrades like insulation, door and window sealing, electrical improvements, and more.

Previously, the credit was limited to $500. However, starting in 2023 and continuing until 2032, the credit has been increased to 30% of the total installation costs. So homeowners can now receive up to 30% of their expenses back, potentially amounting to annual tax credits of up to $3200, depending on the extent of their upgrades.

To learn more about the 25C Tax Credit refer to our detailed guide: What’s the 25C Tax Credit? (And How Can You Get It?).


Are you currently involved in the construction or renovation of a building? 

If you are, you will be directly affected by green building tax incentives. 

Your project has the potential to qualify for significant tax credits amounting to thousands of dollars. For instance, if your single-family or manufactured home meets ENERGY STAR requirements, you could be eligible for a tax credit of $2,500. If your home is certified as a DOE Zero Energy Ready Home (ZERH), you may qualify for an even higher tax credit of $5,000.

Maximizing Green Building Tax Incentives

To maximize the benefits of the 45L Tax Credit, 179D Tax Deduction, and 25C Tax Credit, multifamily developers and homebuilders should consider the following strategies:

  • Understand the Requirements: Familiarize yourself with the eligibility criteria and requirements of incentives to ensure your projects meet the qualifications.
  • Collaborate with Energy Consultants: Partner with experienced energy consultants specializing in green building and tax incentives. They can guide you on how to meet the requirements and optimize energy efficiency in your projects.
  • Integrate Energy Efficiency from the Start: Incorporate energy-efficient design and construction practices from the initial stages of your projects. This will ensure that your buildings meet the necessary standards to qualify for the tax incentives.

Border Patrol’s Presidio Housing Development Earns LEED for Homes Gold Certification

Presidio, Texas is a town steeped in history. Established in the 17th century but settled as early as 1500 B.C. Presidio is now home to just under 4,000 people.

This colorful and historic section of Texas lies right on the Rio Grande River, just across the border from Ojinaga, Mexico, and boasts some of the darkest skies in Texas making it a dream for stargazers. While along the river, it is considered desert land as part of the Chihuahuan Desert in West Texas.

The Project

Because of its proximity to the Mexican border, Customs and Border Protection (CBP) is a large employer in the area. However, due to the smallness of the town of Presidio, housing those border protection officers and their families is a challenge.

Green Insight was brought in to consult on ways to keep design and construction both green and functional on a solution to the housing shortage: a housing project funded by the federal government consisting of 26 single-family attached homes and one single-family detached home for U.S. Border Patrol employees.

Working with the U.S. Customs and Border Patrol design team and W.H. Pacific contractors, we were able to come up with unique solutions to their housing issues while keeping the project green and sustainable.

Project Challenges

The biggest challenge facing the project was a logistical one. While it can boast the darkest skies and best star watching in West Texas, its remote location doesn’t help when it comes to coordinating all the moving parts of a building project.

Located 8 hours by car from our offices, coordinating the construction team with our consulting duties required substantial planning to keep the project on schedule and within budget.

Additionally, the arid desert climate posed its fair share of challenges. Part of our work together was ensuring interior comfort and adequate yet responsible water usage.


To properly coordinate schedules with all parties, strong communication was an absolute must. That meant clear communication prior to our site visits to give crews ample time to make sure everything was ready for all inspections along the way and that all-important final inspection. We also needed to coordinate efforts to ensure all units were complete and ready for final testing.

Our meticulous attention to coordinating all parties paid off. Green Insight was able to successfully certify all 27 homes with a higher status than their original goal of Silver certification.

To combat the environmental challenges, the project utilized a stout building envelope with roof assembly insulation over R40 and walls of R22. These factors help ensure both occupant comfort in the units as well as energy efficiency.

Contractors were also able to strategically plan their planting choices to create landscaping that was both suited for the dry desert heat and didn’t require a lot of water usage.


Through Green Insight’s collaboration with both U.S. Border and Customs Patrol and W.H. Pacific contractors, the Presidio Border Patrol housing development earned:

After completion, the Presidio housing development became a model in sustainability as a piece of the 27 acre site that features both housing and landscaped common spaces.
