Hawaiʻi Green Infrastructure Authority

Please be aware that the Hawaii Green Infrastructure Authority (HGIA) does not advertise our financing programs through the use of cold-calling, door-to-door other similar practices.

We recommend that households perform their due diligence to confirm the identify of sales representatives or callers and ascertain the name of the company that they represent. While there are contractors who are approved to work with HGIA, households should contact us if you have specific questions about HGIA financing.
