shed on ground, permits?

[Ccat]

I need to build an equipment shed.  3 sided, shed roof, on the ground.  About a 3 car garage size. 

Does this require a building permit?

To the best of my knowledge, anything over 120 square feet, more than one story and/or having electrical and/or plumbing run to it must have a permit.

Depends on if you are R zoned or ag zoned.

Most sources seem to point to this for Hawai'i Country:

Structure must be detached, single-story, and the floor area cannot be greater than 600 square feet for land zoned as agricultural or 120 (or maybe 200? there is a conflict in the sources) square feet for land that is not zoned as agricultural. Electrical and plumbing permits are a separate issue.

There's also state law - https://law.justia.com/codes/hawaii/titl...ion-46-88/
Which allows for a wider range and size of agricultural buildings, although it requires notice to and approval from the County that the project is exempt from requiring a building permit.

Best bet is to CYA and call the Department of County Works and see what they say (and then get that in writing and notarized ;)
