Honolulu’s City Council is loosening some long standing lot rules in the urban core, taking a swing at the fine print that has kept many small parcels from ever turning into housing. The move lowers the threshold for apartment development on land already zoned for multifamily use, with the goal of making small lot walk ups and other low rise projects easier to build in town.
The package focuses on adjusting technical zoning standards so that parcels once considered marginal are more likely to pencil out for new housing instead of sitting underused.
What the ordinance changes
Under Bill 6 (2026), CD1 the city would standardize the minimum lot area in A-1 through AMX-3 districts at 5,000 square feet, cut minimum lot width and depth to 60 feet, and simplify floor area ratio calculations so more of each lot can be built out, according to the Honolulu City Council. As reported by Pacific Business News, those tweaks could pull thousands of apartment zoned parcels that were previously too small to redevelop into the pool of sites that actually work for new projects.
Why it matters for housing
Planners and developers say the new rules could finally make smaller multifamily projects, like four story walk ups and compact apartment buildings, financially realistic on lots that used to be borderline at best. A Department of Planning and Permitting estimate cited by Hawaii Business put roughly 3,200 apartment zoned lots between 5,000 and 20,000 square feet into the category of potential redevelopment sites. At the same time, broader Land Use Ordinance updates have been part of a months long effort to overhaul construction, business and housing rules, per Hawai‘i Public Radio.
Supporters and opponents
Industry groups and housing advocates have largely cheered the adjustment as a practical way to unlock stalled parcels and add more rental units without having to rezone entire neighborhoods. But not everyone is ready to celebrate.
Civil Beat has highlighted broader fights over lot size reform in which Department of Planning and Permitting officials warned that sweeping changes can strain water, sewer and street systems if infrastructure does not keep up. At the same time, reform advocates including the Grassroot Institute and local housing coalitions have continued to push for looser standards to make permitting and redevelopment less of a slog.
What comes next
Bill 6 has cleared committee and passed second reading, but it still needs a final vote from the full council and the mayor’s signature before any of the new standards actually kick in, according to city council records. If the ordinance is enacted, the Department of Planning and Permitting will be responsible for implementing the Land Use Ordinance changes, and developers will still have to secure building permits and comply with state and federal construction and environmental requirements, per the city’s planning office.
