About This Market

UPDATED APR 2026

Kihei's plumber market serves a mix of vacation rentals, resort properties, and residential homes, with about 396 licensed establishments statewide creating moderate competition. Costs run 20-30% above mainland averages due to shipping materials across the Pacific and limited supplier options. Resort maintenance contracts and vacation rental turnovers drive steady demand, while older properties in South Kihei need frequent sewer line work due to aging infrastructure and coral soil conditions. The tourist economy creates feast-or-famine cycles tied to visitor seasons.

Working Kihei means navigating Maui County's permit system and understanding Hawaii's strict environmental regulations around wastewater and coastal protection. Get your C-37 license locked down first - the experience requirements are rigid and the exam covers Hawaii-specific codes. Build relationships with local suppliers early because everything ships in, and emergency parts cost double. Focus on vacation rental property managers and resort maintenance contracts for steady work. Keep emergency response capability - tourists don't wait for business hours when pipes burst.
