Maui County Hawaii Fence, SMA, and Water Review Guide

Maui County fence planning may require Public Works, Planning, zoning, flood, or special management area review, and some building projects now need water-use calculations.

Permit takeaway

Maui County's FAQ says a fence may need a permit and directs applicants to Public Works Development Services Administration to confirm whether the proposed fence requires one.

Zoning and placement

Maui directs homeowners to Planning's Zoning Administration and Enforcement Division for fence height, setback, flood development, or special management area questions.

Building and trade review

For larger building work, Maui's water-use calculation method can apply to building permit applications and requests for new or additional water service submitted on or after January 1, 2026.

Call before applying when

Call before building a fence near shoreline, flood, SMA, slope, easement, driveway, or property-line conditions, or when a remodel changes water service demand.
