Mililani Town FAQ
Do I need HOA approval for a backyard fence?
Yes, both MTA and MMA design guidelines typically require architectural review for any new or replacement fence, even within ROH limits.
Can I install a 4-foot wrought iron front fence?
Possibly, but the front yard 36-inch rule would require a setback or landscape buffer, and HOA design review would also apply.
Pearl City FAQ
How tall can my Pearl City fence be?
ROH 21-4.60 caps most Pearl City front-yard fences at 4 feet and side and rear fences at 6 feet. Street frontages with fences over 36 inches need additional landscape screening for sight-line preservation.
Do military rental homes follow the same rules?
