Hawaii · Kohala Coast, Hawaii
Smart Home, Lighting & AV on the Kohala Coast.
Gated resort estates of 5,000 to 10,000 square feet with their own pavilions and ohana, each community with its own design review, a coast that gets vog on bad-wind days and hurricane outages that last weeks, and fiber at 3 gigabits where it reaches. The Kohala Coast wants one system across several buildings, approved by the board, running on its own.
Kohala Coast, Specifically
Several Buildings, One System, Running on Its Own.
Kona-area gated resort communities such as Hualalai, Kukio, Kohanaiki, and Hokulia each impose their own association rules and design review on top of county requirements; at Hualalai even custom homesites follow regulated rooflines, heights, and materials to protect views. Kohanaiki's custom estates typically run 5,000 to 10,000 square feet, often with separate ohana and pool pavilions, which makes fiber between buildings and whole-property control the standard design. Low-voltage, alarm, and telecommunications work is licensed statewide under C-15, C-15a, and C-15b, individual electricians separately, and the county issues and inspects the permits.
The resort belt sits in USGS Lava Flow Hazard Zone 4, vog from Kilauea drifts up the Kohala coast on the wrong wind, and since the eruption phase that began in December 2024, sulfur dioxide spikes have reached about 50,000 tonnes a day. Hurricane Lala in August 2026 brought Hawaiian Electric warnings of outages lasting weeks or months in the hardest-hit rural areas. Hawaiian Telcom offers 3-gigabit symmetrical fiber where the network reaches and aims to make Hawaii fully fiber-enabled by the end of 2026, and Kukio residences averaged $21,975,000 across 2025's sales.

Fiber Between Buildings
Main house, ohana, pool pavilion, and gate on one Lutron and Crestron system, carried between buildings on fiber laid with spare conduit before the drive is finished, with the same keypads and scenes everywhere.

The Board Sees It First
Each community reviews exterior changes against its own guidelines, down to rooflines and materials at Hualalai. Cameras, fixtures, and enclosures are drawn for the submission; the equipment stays inside.
03 · Air and Power
Vog, Salt, and Long Outages
Outdoor cameras and equipment are specified for salt and sulfur, filtration is planned for the rack room, and a generator sized for the house with a battery-backed rack carries the estate through an outage measured in weeks.
At a Glance
Kohala Coast in brief.
- Design review
- Kona-area gated resort communities such as Hualalai, Kukio, Kohanaiki, and Hokulia each impose their own association rules and design review in addition to county requirements; at Hualalai even custom homesites must follow regulated rooflines, structure heights, and materials to maintain visual continuity and protect views.
- The houses
- Kohanaiki custom estate floor plans typically run 5,000 to 10,000 square feet, often with separate ohana and pool pavilions on larger lots; offerings range from town homes to custom estates and home sites priced from $5 million to $25 million, with mandatory club membership on every purchase.
- Licensing
- Hawaii's low-voltage contractor classifications (C-15 electronic systems, C-15a fire and burglar alarm, C-15b telecommunications) are issued by the state Contractors License Board, individual electricians are separately licensed, and the counties issue and inspect project permits.
- Lava and vog
- The Kohala Coast resort belt sits in USGS Lava Flow Hazard Zone 4, a moderate-hazard zone where large flows reach the ocean roughly once every 300 years; vog from Kilauea mostly affects the Kona coast and drifts up the Kohala coast, and since the eruption phase that began in December 2024, sulfur dioxide spikes have reached about 50,000 tonnes per day.
- Electric service
- During Hurricane Lala in August 2026, Hawaiian Electric warned Hawaii Island customers to prepare for outages lasting weeks or even months in the hardest-hit rural areas; crews restored about 99.4 percent of affected customers, with outages in places like Wood Valley persisting for weeks.
- Internet
- Hawaiian Telcom launched 3-gigabit symmetrical Fioptics service statewide in fiber-enabled areas, the fastest speed available in Hawaii, and announced plans to make Hawaii the first fully fiber-enabled state by the end of 2026.
- Market
- Kukio recorded seven sales in 2025, three condominiums and four residences, with average prices of $21,975,000 for residences and $12,950,000 for condominiums at $3,773 per square foot; Kohanaiki's 2026 median runs near $9 million, with custom estates typically $7 million to $22 million and oceanfront homes $25 million to $50 million or more.

Cave Watch →Questions From Kohala Coast
Kohala Coast, Answered
Who installs Lutron and Crestron systems on the Kohala Coast?+–
Cave Group does. We are a Crestron Elite Gold Partner and Lutron Gold Dealer based in New York, and we design, install, and service lighting control, shades, cinema, outdoor audio, networking, security, and backup power for estates in Hualalai, Kukio, Kohanaiki, Mauna Kea, and Mauna Lani on a project basis, on site with Hawaii-licensed electrical and electronic-systems contractors.
Can one system cover the main house, the ohana, the pool pavilion, and the gate?+–
Yes, and on these lots it should. We link the buildings with fiber in conduit laid before the drive is finished, give each one a small equipment location, and run them as one Lutron and Crestron system, so keypads, touch screens, and the app work the same way everywhere on the property.
What do vog and salt change?+–
Outdoor cameras, speakers, and fixtures are specified for salt and sulfur, the rack room gets filtration, lens housings and enclosures are chosen for corrosion, and a maintenance visit is scheduled rather than discovered. Inside, the system is the same one we build anywhere.
What about the grid?+–
Hawaii's island grids cannot borrow power from a neighbor, so Hawaiian Electric carries its own reserves and the outages are long when they come: rolling blackouts on Oahu in January 2024, Hurricane Lala on Hawaii Island in 2026 with warnings of weeks or months in the hardest-hit areas, Hurricane Lowell taking power from more than 90 percent of Kauai that September, and Public Safety Power Shutoffs on Maui in fire weather. A battery-backed rack and a generator sized for the house are part of every Hawaii design, with the emergency-generator exemption in the state noise rules met through best available control technology.
How does a New York firm work on a Hawaii Island estate?+–
On a project basis. Our offices are in New York and New Jersey, and our hospitality work includes hotels; the design and the drawings happen with your architect and builder from there and on site at the milestones that need it, the installation and commissioning happen on site, and Cave Watch supports the system remotely afterward. The permitted trades Hawaii requires, a licensed electrical contractor for line-voltage work and the C-15 electronic-systems and C-15a alarm classifications for low-voltage and alarm work, are local, and the licensed contractor pulls the county permit.
