Two separate approvals, not one
Your HOA architectural review committee and your local permitting office are unrelated processes with different rules. Passing one does not satisfy the other, and they can be at odds, with an association style that exceeds a municipal height limit or vice versa.
Start with the HOA, because their approved material list is usually the narrower constraint, then confirm the jurisdiction requirements for height, placement and corner lot visibility.
- HOA: material, color, height, style, sometimes placement
- City or county: height by yard location, setbacks, sight triangles
- Pool barriers: separate safety requirements enforced at inspection
- Easements: utility and drainage easements affect where posts can go
