building a tiny house or garage do not qualify as an Ag Building
Permits not required for structures smaller than a specified square footage (per zoning; 120sf in R, 600sf in A) provided they are without plumbing or electrical, not used for habitation, and correctly situated (outside of setbacks, and far enough apart from other structures).
HRS 215 carves out additional exemptions for ag structures on ag-zoned lots that are 1 acre or larger, especially where these are "pre-engineered" (shipping containers, greenhouse from a kit). Permits required from County for any plumbing/electrical, the mayors lobbied for this requirement out of fear that people would use the State-level exemptions to end-run the County permitting process.
Reality on the ground is that County will make it up as they go along, but only if you attract their attention somehow (eg, neighbors complain).
Latest building code includes extensive regulations for "tiny homes", these may be relevant.
