KCC §8-9.3

How to Calculate Allowed Density and Land Coverage

Read the official text at ecode360.com ↗

This section explains how to count the land area when figuring out how many homes or how much building coverage is allowed. It says you use the lots or parcels listed in your permit application. If part of your land is in the Open District due to environmental constraints, you can sometimes include that area in your calculations, but only up to a limit. It also says that open space areas in a subdivision are automatically zoned as Open District.

The ordinance, as written (Kauaʻi County) — Calculation of Densities and Land Coverage

A copy, taken August 22, 2026. The version published by Kauaʻi County is the one that governs, and it may have changed since. Check it before relying on anything here.

The area in connection with which the permissible densities shall be calculated shall consist of that lot or lots, or parcel owned or controlled by the applicant designated in the permit application as part of the land development for which the permit is sought.When an area is included in the Open District because it is within the Constraint District, the precise boundary of the Open District shall be established to reflect the physical or ecological considerations upon which the particular Constraint District is based, regardless of lot or parcel boundaries. In those cases, that portion of the lot or parcel included in Open District may be included in any calculation of permitted densities and land coverage to be carried out on that portion of the parcel that is not within the Open District, provided that the total amount of density and land coverage shall be no more than one and one-half (1-1/2) that which would be permissible if the Open District portion of the lot or parcel was excluded from the calculation.Open Space. When a subdivision meeting the density and parcel area requirements of Secs. 8-4.4, 8-8.2(c), 8-8.4, 8-8.6, 8-9.2(b) and 8-9.2(c), results in the designation of areas within the subdivision for open space use, the areas shall be designated on the final subdivision map and Zoning Map as open space, and, in that case, upon approval of the final subdivision map the areas shall automatically be transferred to the "Open District, Special Treatment-Open Space" for zoning purposes.
