Off-Grid Communities in Hawaii

Confirm current requirements with the state agency before your trip. Rules and fees change every season.

• Building Permits

  Any new construction or significant alteration of a structure in Hawaii requires a building permit from the respective county's Department of Public Works. This includes dwellings, outbuildings, and major infrastructure like water tanks or foundations. Compliance ensures safety and adherence to local zoning and construction standards. Requirements and processes differ across counties.

• Wastewater System Permits

  Installation or modification of any wastewater system, including septic tanks, cesspools (where still permitted for repair/replacement), and alternative treatment systems like composting toilets with greywater discharge, requires a permit from the Hawaii Department of Health. Proper design and installation are critical for environmental protection and public health.

• Agricultural Dedication for Tax Benefits

  To qualify for reduced property tax rates under agricultural dedication, landowners must apply to their respective county's Real Property Tax Division. This typically involves demonstrating that the land is actively used for commercial agricultural production, meeting specific acreage or income thresholds, which vary by county.

• Water Use Permits (for Wells/Surface Water)

  For drawing water from a well or surface water body, a Water Use Permit may be required from the Commission on Water Resource Management (CWRM), especially in designated Water Management Areas. Rainwater catchment for residential use generally does not require a permit, but potable systems must meet DOH standards.

1. 01

   1. Define Your Off-Grid Vision and Resource Needs

   Clearly outline your goals for off-grid living, including desired level of self-sufficiency, preferred climate (wet/dry, elevation), and essential resources like water and energy. This helps narrow down potential islands and specific regions within Hawaii.

2. 02

   2. Research County Zoning and Building Codes

   Each Hawaiian county has distinct zoning ordinances, building codes, and permitting processes. Thoroughly research the regulations for your target county, paying close attention to agricultural zoning, owner-builder provisions, and requirements for alternative systems like rainwater catchment and composting toilets.

   3. Visit Potential Properties and Engage with Local Communities

   Before committing, visit Hawaii to experience the microclimates, assess road access, and evaluate potential properties firsthand. Connect with existing off-grid communities or homesteaders in your areas of interest to gain practical insights and understand local dynamics.

4. 04

   4. Conduct Thorough Due Diligence on Land

   Prioritize due diligence, including professional surveys, soil testing, water source verification (e.g., catchment potential, well reports), and checking for easements or covenants. Understand the specific challenges and opportunities presented by the land's unique characteristics.

5. 05

   5. Secure Necessary Permits and Plan for Infrastructure

   Before beginning construction, obtain all required building, wastewater, and electrical permits from the relevant county and state agencies. Develop a comprehensive plan for your off-grid infrastructure, including power systems, water collection, and waste management, ensuring compliance from the outset.
