Housing legislation debates often focus on density numbers, but for developers underwriting projects in Honolulu, the more critical variable is whether a project can be approved as of right. Bill 18, introduced by Council Vice Chair Andria Tupola, aims to expand the Chapter 32 Affordable Rental Housing program—known as Bill 7—into additional zoning districts, including apartment, business, and Waikiki's apartment precinct. The program offers relaxed zoning standards, tax relief, and fee waivers in exchange for at least 80% of units being rented at affordable rates for 15 years. For 2026, the affordability threshold is $93,400 for a single person and $133,400 for a family of four.
Currently, most market-rate residential development on Oahu goes through the 201H process, which requires political approvals and public hearings, creating uncertainty that developers price conservatively. Mike Perkins of The Bratton Team at Colliers International Hawaii notes that this uncertainty adds significant costs. Bill 18 would allow Chapter 32 projects to proceed directly to building permits, providing developers with certainty from the outset. This compresses timelines, reduces carrying costs, and lowers the cost of capital, potentially widening the pool of investors willing to participate.
The need is urgent: Honolulu requires 27,710 new housing units between 2023 and 2027, according to the 2024 Hawaii housing planning study. A by-right pathway could speed delivery by months or years. Other regulatory changes, such as Maui's Bill 9 phasing out short-term rentals and Bill 88 creating new rezoning pathways, are also affecting investment decisions. Additionally, a 2024 state law requires all counties to permit two accessory dwelling units per lot by year-end, which Perkins says mainly impacts single-family housing rather than commercial multifamily development.
Perkins argues that regulatory clarity now weighs more heavily in underwriting than interest rates. Entitled land may still require reaffirmation of approvals, introducing time costs that buyers discount. Bill 18's conversion of a discretionary process into a defined one removes a discount that currently applies across the market, benefiting not only affordable housing but the broader investment landscape. For developers and investors, the regulatory pathway attached to a site is as important as its physical characteristics. Two parcels with identical zoning may not be equivalent if one qualifies for by-right approval and the other does not. This difference affects carry costs, financing terms, and buyer pool breadth.
Local expertise is crucial in this environment. Current Hawaii inventory and monthly market statistics show what is available and how it is pricing, but knowing which approval pathway applies to a property turns that data into an investment decision. As Hawaii's approval framework becomes more defined, sites positioned to use by-right pathways stand to benefit first.
