Privacy fences on single-family lots may not exceed 6 feet, while rear-yard duplex fences may reach 8 feet. Front-yard ornamental metal fencing is capped at 4 feet above sidewalk.

Cedar Park's design standards restrict front-yard fencing to ornamental metal; privacy fences in side and rear yards are typically wood or masonry. Chain link is generally limited or prohibited on residential frontages.

Retaining walls in front yards may not exceed 4 feet in height above sidewalk per Cedar Park design standards; engineering and a building permit are required for taller walls under the adopted 2021 IRC.

Cedar Park's zoning code does not require neighbor consent for a fence, but the Texas Property Code and common law govern shared-fence cost-sharing and boundary disputes.

Cedar Park requires pool barriers at least 48 inches tall with self-closing, self-latching gates per the adopted 2021 ISPSC and Texas Health & Safety Code Chapter 757.

Hot tubs and spas in Cedar Park require a permit but are exempted from the standard pool barrier rules if equipped with a listed, lockable safety cover that meets ASTM F1346.

Residential pools must meet ISPSC entrapment, alarm, and barrier rules; conduct at city pools and public water playscapes is governed by Article 8.03 of the Code of Ordinances and Parks Department rules.
