For many, the idea of living off-grid on the Big Island of Hawaiʻi sounds like a dream – solar panels, rain catchment, a lush jungle backdrop, and absolute peace and quiet. The Big Island, with its expansive land and flexible zoning in some regions, makes that dream seem tantalizingly possible. But how realistic is it, really?
Whether you’re picturing a self-sustaining homestead or a remote retreat to escape the hustle, here’s what you need to know about going off-grid on the Big Island.
Why the Big Island?
The Big Island is one of the best places in the state, and arguably the country, for off-grid living. Here’s why:
- Abundant Land: Properties in areas like Puna, Kaʻū, and parts of South Kona or Ocean View offer large parcels at relatively affordable prices.
- Year-Round Growing Season: With the right microclimate, you can grow your own fruits and vegetables year-round. Make sure you do sufficient research into the areas you’re looking at.
- Flexible Infrastructure: Many areas don’t have access to county utilities, so solar, rainwater catchment, and septic systems are already the norm – not the exception.
- Excellent Views: No shortage of amazing views. With the mountains centrally toward the middle of the island, many areas have auditorium seating for the Pacific Ocean.

The Dream: What Makes It Appealing
- Sustainability & Self-Reliance – Grow your own food, generate your own power, and live in harmony with the land.
- Lower Cost of Living – This one means playing the long game. With no utility bills and cheaper land, monthly expenses can be lower – but setup costs matter. Don’t immediately expect your monthly expenses to come down.
- Peace & Privacy – Many off-grid properties are secluded, surrounded by native forest or lava fields. Perfect for introverts, artists, or those looking for a slower pace of life. The freedom afforded by living off-grid means the world is your oyster.
- Freedom to Build Creatively – In many rural areas, zoning and building regulations are less restrictive than urban centers – giving you flexibility to design your lifestyle.
The Challenge: What to Be Prepared For
- Infrastructure Costs – Setting up reliable solar power, a rain catchment system, a septic tank, and possibly a backup generator can cost thousands of dollars. More if you’re planning on hiring people to get these things set up properly.
- Maintenance is Constant – Catchment systems need maintenance and cleaning. Solar batteries degrade. Roads may wash out. Nature is beautiful but relentless. Be ready to get your hands dirty.
- Access & Isolation – Some properties are far from paved roads, services, or even cell reception. Getting groceries can mean a 30+ minute drive. Without a proper catchment filtration system your water will be unpotable and must be boiled prior to drinking.
- Resale Can Be Tricky – Not everyone wants to live off-grid, so selling your property in the future may take longer or appeal to a niche buyer pool.
Is It Legal to Live Off-Grid in Hawaiʻi?
Yes – but with caveats. Off-grid living is legal, as long as your home meets building and health codes. For example:
- Rain catchment must follow DOH guidelines.
- Septic systems must be permitted and inspected.
- Structures must comply with the county’s building codes, even in rural areas.
Some buyers try to go the “unpermitted” route – but that often leads to issues with insurance, financing, or future resale. Always make informed decisions and if you aren’t sure about the proper way to proceed, ask a professional.
Pro Tips for Going Off-Grid
- Work with a local realtor who knows the area and the permitting process.
- Budget for infrastructure, not just land. $100k land might need $50k+ in systems.
- Talk to neighbors. They can give invaluable insight into what works – and what doesn’t – in the area.
- Start small. A simple permitted cabin can be your base while you learn and expand.
- Be ready to learn. DIY is going to be your best friend and a good way to decrease expenses.
Final Thoughts: Dream or Challenge?
Truthfully, off-grid living on the Big Island is both. It’s not for everyone – but for those who prepare properly, it can be deeply rewarding. The key is realistic expectations and a willingness to adapt when things don’t go according to plan.
