Aloha and welcome! I am a recent transplant from CA to Hawaii also. We moved in March 2003. How exciting for you, but I don't envy your move. I hope you are selling everything before you move!!

As far as the fence ordinance, you would have to check with the local authorities on Kauai as they would be the ones to tell you. If you bought the house without a fence around the pool, it probably was ok but you are right to question it. I would call (808)241-6303, which is the number to the Kauai Public works Dept. They should be able to direct you to the correct department. Good luck on your move.
Also, if coming with pets, make sure they meet the quarantine guidelines, aloha, Melanie
this site also has useful info, http://www.kauaigov.org

Aloha Melanie,
Thanks for the reply. We will call for info after we arrive.
As for pets, we are bringing our Borzoi 'Tasha with us. DH has a folder about 1/2 inch thick he started over four years ago dedicated to bringing pets into Hawai'i. We have (I hope) jumped through all the hoops to get a "Release at Airport" for her.
See my new ? about ants.
Aloha, Liz

Yes -- swimming pools are considered an "attractive nuisance," and you either need a fenced yard or a fenced pool (with a self-locking latch) to guard against someone coming onto your property and drowning. Big liability.
