Orange County horse property

The short answer There is no Orange County rule

Fourteen jurisdictions, fourteen different answers. A one-acre lot might permit four horses, six, eight, ten, fifteen — or none at all, depending entirely on which side of a city line it sits.

Three OC communities have no numeric limit whatsoever, and one has no public horse law at all. Neither of those means what people assume.

The single most useful table in Orange County horse property

Nobody publishes this, so far as we can find. Every figure is read from the adopted code or specific plan, and each links through to the page where it is cited and dated.

Jurisdiction	Minimum lot	How many
Yorba Linda	15,000 sq ft by right	1 at 10,000 → 6 at an acre, +2 per acre
Orange Park Acres — county side	none stated	1 per 5,000 sq ft (1 per 3,500 with a permit)
Orange Park Acres — city side	20,000 sq ft and R1-20 zoning	2, +1 per 10,000 sq ft, hard cap 6
Anaheim Hills	1 acre — or 22,000 sq ft in RH-2	1 per quarter-acre
Villa Park	10,000 sq ft	2 → 6 above 45,000 sq ft
San Juan Capistrano	by district (RA 2.5 acres)	1 per 10,000 sq ft; permit bands at 4 / 6 / 10
Trabuco Canyon	20,000 sq ft	4 → 15 at two acres
Fullerton	¾ acre net, R-1 only	2, +1 per 15,000 sq ft, cap 5 without a permit
Laguna Hills	15,000 sq ft	2 animal units → 10 maximum
Newport Beach — Santa Ana Heights	under 10,000 sq ft permitted	1 → 2 at 10,000, 3–6 with a permit
Brea — Olinda Village only	1 acre	4, +1 per 15,000 sq ft
Silverado / Modjeska	—	no numeric limit
North Tustin — Lemon & Cowan Heights	—	no numeric limit
Coto de Caza	—	no public law at all

Scroll the table sideways to see all three columns.

Read that table before you fall in love with a listing. A two-acre parcel in Trabuco Canyon and a two-acre parcel in Anaheim Hills are, on paper, fifteen horses and eight horses respectively — and in Coto de Caza the same two acres has no published answer.

Why Orange County is this fragmented

Because there is no single regulator. Some of this land is in a city, some is unincorporated county, and some communities are split down the middle. Three things follow that catch people out.

The county has an equine district, and it exists almost nowhere

Orange County's Zoning Code contains an “E” Equine Combining District (Sec. 7-9-41) with the generous rule everyone quotes: one horse per 5,000 square feet, or one per 3,500 with a Recreational Equine Use Permit.

It applies only where the district symbol carries a parenthetical (E). There are six such polygons in the entire county, about 393 acres between them, and 99.7% of that acreage is in Orange Park Acres.

So the county's headline horse rule does not reach Coto de Caza, Trabuco Canyon, Silverado, Modjeska or North Tustin. Anyone quoting one-per-5,000 to you about a property outside OPA is quoting a rule that does not apply to it.

White-fenced paddock and shelter on an Orange County equestrian property — The same paddock, on two sides of a city line, can be governed by one horse per 5,000 square feet or by a hard cap of six.

“No limit” is not the same as “no rules”

Three OC communities have no numeric horse cap: Silverado and Modjeska Canyon, and North Tustin's Lemon Heights and Cowan Heights. In each case the reason is the same — the (E) district carrying the numbers is not mapped there, and the base zoning simply does not state a figure.

What still governs is real: a 25-foot separation from any residential window on an adjoining building site, base-district setbacks, a prohibition on keeping animals commercially without a permit, and the County Health Officer's authority. In the canyons, fire hazard classification does more to constrain a property than any animal rule.

And in North Tustin there is a genuine definitional question — the permission runs through a section about “domestic pets and animals,” while the code defines “equine” separately. Get a written determination from OC Development Services rather than relying on the absence of a number.

Some of the best-known names are the least regulated

Coto de Caza is the clearest case. Orange County's most horse-identified community has no public horse-count law whatsoever — its Specific Plan is silent, and the fall-through provision caps dogs and cats then delegates everything else. What governs your horses there is the recorded CC&Rs, which are private and not published.

The mirror image is Fullerton, which has a more precise ordinance than the county's and almost no land to apply it to — roughly 2% of its R-1 parcels reach the three-quarter-acre net threshold.

Where the horse property actually is

Concentration matters more than county-wide totals. In practice Orange County horse property clusters in a handful of places:

Yorba Linda — the largest by-right inventory, roughly 3,100 parcels, though that is still only about one home in six. The tightest pocket announces itself in the street names: Cleveland Bay, Trotter, Red Roan, Welsh Pony, Paso Fino.
Orange Park Acres — about 1,600 parcels across two jurisdictions, roughly half of which can keep horses by right.
North Tustin — the largest large-lot inventory of the smaller markets, with around 1,400 parcels of half an acre or more.
Anaheim Hills — concentrated and nameable rather than widespread: Peralta Hills and the Mohler Drive corridor, about 940 parcels.
The canyons — Silverado, Modjeska and Trabuco: large parcels, no numeric caps, and Very High fire hazard throughout.
Nellie Gail Ranch in Laguna Hills and Santa Ana Heights in Newport Beach — small, distinct, and each with its own purpose-written rules.

Verified September 10, 2026. Each figure above is drawn from the research behind the individual city page, where it is quoted, cited to section and dated. Where a community has no page yet — Laguna Hills, Newport Beach, Brea and North Tustin — the figures come from the adopted code or specific plan, checked the same way.

Confirm any specific parcel with the city or county that has jurisdiction over it. In Orange County that is genuinely the first question, not a formality: several communities here are split between two regulators, and in Orange Park Acres you cannot tell which one applies from the street name. This page is written by a real estate broker, not by any city or the County.

What Sharon does with all of this

Establishes the regulator before anything else, because in this county that single fact changes the answer to every other question. Then reads the actual parcel against the actual rule — not the county rule, not the reputation of the neighbourhood, and not what the listing says.

She has closed horse property in Yorba Linda, Orange Park Acres, Silverado and Fullerton, on both sides of the Orange Park Acres line. If a property does not work for the horses you own, she will say so before you write the offer.
