Carports are being pitched as a cheaper alternative to a garage for Hawaiʻi homeowners, and the case rests more on sun damage than on rain.

• Hawaiʻi's strong sun does more harm to a parked car than rain does.
• Constant sun fades paint, wears down the interior, and breaks down rubber and plastic parts.
• A carport blocks most of that damage at a much lower cost than building a garage.
• Covered parking can also add usable space and curb appeal to a house.

Outlook: Expect covered parking to stay a common upgrade for island homeowners looking to protect a car without garage-level spending.
