Thinking about buying land near Honokaʻa or elsewhere on the Hāmākua Coast? A beautiful parcel can be full of potential, but raw land comes with questions you need to answer early. If you want to avoid expensive surprises, it helps to know what to verify before you commit. This guide walks you through the key early steps so you can move forward with more clarity and confidence. Let’s dive in.
Start With Your Intended Use
Before you compare views, price, or acreage, get clear on what you want the land to do for you. On the Hāmākua Coast, that first decision shapes nearly everything that follows, including zoning review, permitting, utility planning, and timeline.
The County’s Hāmākua Community Development Plan covers Honokaʻa, Kukuihaele, Ahualoa, Paʻauilo, Laupāhoehoe, Honomū, and nearby communities. These plans are official long-range planning documents adopted by ordinance, so they are a useful starting point when you want to understand the broader planning context for the area.
Your intended project also matters from a legal and permitting standpoint. Hawaiʻi County notes that you may need to determine whether your project is a dwelling, farm dwelling, additional farm dwelling, second residence or ohana, or a non-agricultural use that may require a permit such as a special permit, use permit, change of zone, state land use boundary amendment, or SMA use permit through the County land use permit process.
If the parcel is in a subdivision, there is another layer to check. The County states that CC&Rs and association rules can be more restrictive than County code, which means a project that appears acceptable under County rules may still not comply with private subdivision requirements.
Questions to Answer Early
- Will you use the land for a primary home, future home, farm-related use, or another purpose?
- Is the use clearly allowed, or will it require additional approvals?
- Is the parcel subject to subdivision rules that are stricter than County regulations?
Verify Zoning Before You Commit
Two parcels can look nearly identical online and still offer very different build options. That is why zoning should be one of your first screens, not something you check after you are emotionally committed.
Hawaiʻi County explains that land use is shaped by several layers, including State Land Use classifications, County zoning districts, General Plan designations, and other controls under County zoning and land use guidance. Chapter 25 governs permitted uses, setbacks, height limits, and similar development standards.
The County zoning quick reference identifies districts such as RS, RD, RM, and RCX for residential uses, along with agricultural-focused districts like RA, FA, A, and IA, each with different minimum building-site requirements according to the zoning reference PDF. In practical terms, this means one Hāmākua parcel may support your plans while a nearby parcel may not.
Because of that, it is smart to confirm zoning and allowed uses before your deposit becomes hard or your due-diligence period ends. This is especially important if you are buying from afar or relying on listing remarks.
Why Zoning Checks Matter
- Allowed uses can vary from parcel to parcel
- Minimum lot or building-site standards may affect your plans
- Setbacks, height limits, and overlays can change what is actually buildable
- Agricultural zoning does not automatically mean every type of residential use is allowed in the same way
Screen Coastal and Shoreline Constraints
Some Hāmākua parcels come with dramatic ocean proximity, but shoreline-area property needs extra review. If the lot is near the coast, you will want to understand whether the Special Management Area applies and how shoreline setbacks may affect your plans.
Hawaiʻi County’s Special Management Area guidance says shoreline setbacks are typically established early in permitting, and lots abutting the shoreline have a minimum 40-foot shoreline setback. That can influence where you place a home, driveway, lanai, or other improvements.
The County’s Hāmākua shoreline access guide also notes that some shoreline access ways can be dangerous due to seasonal high surf and hazardous rock access. For buyers, that is a practical reminder to look beyond the view and understand real site conditions.
Confirm Legal Access
Access is one of the most important early checks for raw land. If legal or practical access is unclear, it can affect financing, permitting, utility planning, and overall usability.
Hawaiʻi County subdivision code states that each subdivided lot must abut a public street or approved private street, and no lot may be platted without street access under the County subdivision code. The same code also notes that utility easements may be required outside street widths.
That means you should verify not only that the parcel appears reachable, but also that its access is legally established and suitable for your intended project. On larger or more rural parcels, this step deserves close review early in the process.
Ask About Water Availability Early
Water is another major question for land buyers in and around Honokaʻa. Even if the parcel is in an area served by a County water system, you still need to verify actual availability for your project.
The County Department of Water Supply says its Water Resources and Planning team can answer water availability questions, and County water-planning materials explain that DWS researches water availability for proposed projects and provides a letter to Planning stating whether water is available and what improvements may be required, as described in this DWS planning document.
For Hāmākua specifically, the current Water Board district list includes Honokaʻa, Kukuihaele, Paʻauilo, and Āhualoa under the Water Board information. The County water-plan chapter also describes the Haina Water System as serving Honokaʻa and Haina, while the Kukuihaele system serves Kukuihaele and Kapulena.
This is why water should be a real due-diligence item, not an assumption. A parcel may be in a service area, but your project still needs confirmation from the appropriate agency.
Understand the Wastewater Path
Wastewater planning can affect lot feasibility, build cost, and timing. On land that is not served by public sewer, you will want to understand early what type of wastewater system may be needed and what approvals are required.
The Hawaiʻi State Department of Health says for individual wastewater systems, you should keep the TMK handy and have a licensed engineer perform the percolation-test and plan-submittal work. The same guidance also states that new buildings may not use new cesspools.
Timing matters here too. The State notes that wastewater-system approvals become invalid if a County building permit is not issued within one year after wastewater approval, or if construction does not begin within one year.
County subdivision code also says that where a property will not be served by a public sewer, lot-size decisions for sewage disposal must conform to State health requirements and account for both water-supply and sewage-disposal issues. In short, wastewater is not something to leave for later.
Build a Realistic Permit Timeline
Land purchases often feel simple at closing and complex right after. That is because the real work starts when you move from ownership to project planning.
If your plans require land-use approvals, Hawaiʻi County currently routes applications for items such as additional farm dwellings, ohana dwellings, special permits, use permits, change of zone, state land use boundary amendments, and SMA use permits through the Planning Department process. For rezoning, the County notes that applicants must apply to the Planning Commission.
For permit submittals, the County says departments have moved to EPIC online application systems, so it helps to organize your documents before starting. Building permits are issued by the Department of Public Works Building Division, not the Planning Department.
According to the County’s building permit applicant checklist, your package may require a licensed design professional, a Property Owner Declaration, proof of ownership if the property was recently purchased, and other project-specific forms. The checklist also notes a plan-review fee equal to 20 percent of the permit fee, with a minimum of $50, and incomplete applications may be returned.
The County’s EPIC building permit materials show a multi-step review process that includes intake, completeness checks, land-use review, and multi-agency review. If your project involves wastewater or engineering issues, your timeline may be longer than a basic permit.
Coordinate Utilities and Your Team in Parallel
One common mistake is waiting until after closing to line up the people and systems your project will need. A smoother approach is to build your team as soon as the parcel clears your early due-diligence screens.
For electric service, Hawaiian Electric advises builders, developers, contractors, and homeowners to start the electric service request process as early as possible because material shortages are extending lead times. Its Customer Interconnection Tool is the portal for new or upgraded service requests.
From a practical standpoint, buyers are often best served by moving several steps forward at once. Once zoning, access, water, and wastewater look workable, it helps to line up your lender, designer, contractor, and utility contacts in parallel rather than waiting until every other item is complete.
