Summary
Yolo County does not print its own pool-fence dimensions: Sec. 8-2.1011(f) of the zoning code sends every private pool to the fencing and barrier rules adopted with the building code, while the rest of Sec. 8-2.1011 sets the pool's lot placement, setbacks, and equipment clearances.
Any pool, pond, lake, or open tank not located within a completely enclosed building and containing, or normally capable of containing, water to a depth at any point greater than eighteen (18) inches, when used as a private swimming pool in any zone, shall comply with the following requirements: (a) Such pools shall be used solely for the enjoyment of the occupants of the premises on which they are located and their guests and not for instruction or parties when fees are paid therefor, unless a Use Permit is first obtained. ... (f) Fencing and barrier requirements set forth in Yolo County Code Section 7-1.04(h).

Full Breakdown
Sec. " Subsection (a) limits use to the residents of the property and their guests, requiring a Use Permit before the pool can be used for paid instruction or parties. Subsection (b) requires the pool to sit on the rear half of the lot or at least 50 feet from the front property line. Subsection (c) requires the same side and rear yard setbacks as an accessory building, with a hard minimum of 5 feet from any lot line, and caps pool coverage at 40 percent of the required rear yard; subsection (d) then excludes the pool's surface area from the parcel's overall lot-coverage limit for buildings.
Subsection (e) keeps filter and heating equipment out of any yard next to a public street, at least 3 feet from a side or rear line, and at least 10 feet from a neighboring dwelling's living area unless the equipment sits in a soundproof enclosure. " That cross-reference ties the pool barrier standard to the county's building-code amendments, which incorporate the 2019 California Residential Code's Appendix V, the Swimming Pool Safety Act (Sec. 02(b)), the source of the enclosure standards a Yolo County inspector checks before signing off on a new pool.
Violations & Fines
A pool built, fenced, or sited out of compliance with Sec. 8-2.1011 is subject to the county's standard code-enforcement process: a notice of violation, a stop-work or correction order from the Chief Building Official, and misdemeanor liability under Sec. 1-2.01, punishable by up to a $500 fine, up to six months in county jail, or both, with every additional day of noncompliance charged as a separate offense.
