Ramona San Diego Farm and Ranch Zoning: A70 vs A72 Explained

What are the real zoning and land use restrictions you need to understand before buying a farm or ranch property in Ramona, San Diego in 2026?

Ramona farm and ranch parcels fall under the County of San Diego Zoning Ordinance (not the City), and the two agricultural zones you’ll encounter most often, A70 (Limited Agriculture) and A72 (General Agriculture), determine everything from what animals you can keep to whether you can run a dairy operation.

Why Ramona Zoning Matters More Than Ever in 2026

If you’re shopping for agricultural land anywhere in San Diego County right now, you already know the market has shifted. Over the three months ending August 2026, San Diego home prices rose 5.2% year over year, with a countywide median sale price of $999K. But Ramona is a different world from coastal neighborhoods or suburban corridors like Carmel Valley or Scripps Ranch. Here, it’s not just about the price per square foot. It’s about what the land lets you do.

I say this all the time: a cloudy mind can’t make decisions. And zoning confusion is one of the fastest ways to cloud your thinking when you’re looking at a 5-, 10-, or 20-acre parcel in Ramona. With 18 years and over 275 closed transactions across San Diego County, I’ve watched buyers fall in love with a property’s views and acreage only to discover that their planned equestrian facility, U-Pick operation, or livestock setup wasn’t compatible with the parcel’s zone box. Understanding A70 versus A72 before you write an offer is not optional. It’s essential.

How the County of San Diego Zone Box System Works in Ramona

Here’s the first thing that trips up almost every farm and ranch buyer: Ramona is an unincorporated community. That means it falls under the County of San Diego Zoning Ordinance, not the City of San Diego Municipal Code. They are completely different systems.

The County uses a multi-layered “zone box” with up to 14 separate designators. Your parcel doesn’t just have one zoning label. It has layers that cover:

• Use regulations (A70, A72, RR, etc.), which define broad categories of what’s permitted
• Animal regulations, which specify exactly how many horses, cattle, goats, or poultry you can keep
• Development regulations, which control setbacks, height, lot coverage, and building footprints
• Special area regulations, including airport overlays and environmental protections

So when you see “A70” on a listing, that’s only one piece of the puzzle. Two A70 parcels side by side can have wildly different animal allowances depending on their animal designator. What I tell my clients is to always pull the full zone box from the County’s Planning and Development Services before making assumptions about what the land can support.

What A70 (Limited Agriculture) Zoning Allows in Ramona

A70 is the workhorse agricultural zoning designation you’ll encounter across Ramona’s farming landscape. It’s intended for crop and animal agriculture, with the number and type of animals governed by neighborhood-level regulations. Here’s what you can do under A70:

• Family residential use. You can absolutely build or maintain a single-family home. Limited Agriculture does not mean “no house.”
• Crop production and horticulture. Orchards, row crops, vineyards, and flower farms are all permitted.
• Animal keeping. Horses, cattle, goats, poultry, and other livestock are allowed, but the specific numbers depend on your parcel’s animal designator, not the A70 label itself.
• Nurseries. Growing and cultivating plants for sale on-site is permitted.
• On-site sales. You can sell agricultural products grown on your premises directly to customers.
• Guest living quarters. One guest quarters unit is allowed per legal lot.
• Farm employee housing. Permitted as an accessory use when tied to commercial agriculture on the same parcel or another parcel you own.

One buyer I worked with found a beautiful 8-acre A70 parcel in Ramona with plans to run a small goat dairy. The A70 zoning supported animal keeping, but when we pulled the full zone box, the animal designator capped the number of goats well below what a viable dairy operation required. We pivoted to a different parcel with a more permissive animal schedule, and that decision saved months of permit headaches.

Barn and Agricultural Building Rules Under A70

Your barn and storage buildings under A70 are limited to one story, not exceeding 12 feet in height. You can go up to 24 feet if the structure meets main building setbacks. Floor area scales with acreage:

• Under 1 acre: 1,000 sq ft maximum
• 1 to under 2 acres: 1,500 sq ft maximum
• 2 to 4 acres: 2,000 sq ft maximum
• Over 4 acres: An additional 200 sq ft per acre, up to 5,000 sq ft total

What A72 (General Agriculture) Zoning Allows in Ramona

A72 is the broader, more permissive agricultural designation. If A70 is the family farm, A72 is the working ranch. The critical difference? A72 supports more intensive agricultural operations.

Everything permitted under A70 is also permitted under A72, plus:

• Dairy operations. A72 explicitly allows dairy farming, which A70 generally does not without special permits.
• Large-scale farming. More intensive crop and livestock operations are supported under A72’s framework.
• Intensive animal raising. The scope of permitted animal activities expands significantly compared to A70.

Both zones share the same barn and agricultural building restrictions. Both allow guest quarters and farm employee housing under identical conditions. And both qualify for the County’s agricultural preserve program (Williamson Act), which can reduce your property taxes in exchange for maintaining agricultural use.

So what’s the real-world impact? A couple relocating from Northern California reached out to me about a 15-acre Ramona property they found online. They wanted to raise cattle and eventually add a small dairy component. The property was zoned A70, which initially seemed fine. But when I walked them through the distinction between A70 and A72, they realized the dairy component would require either a zone change or a Major Use Permit under A70, both of which add time, cost, and uncertainty. We refocused the search on A72 parcels, and they closed on a property that supported their full operation from day one.

The Animal Designator: The Hidden Layer Most Ramona Buyers Miss

Here’s something that surprises nearly every buyer I work with, and after 275 transactions across San Diego County, I’ve seen this confusion more times than I can count. Your animal rights do not come from the A70 or A72 designation alone. They come from the animal designator in your zone box.

The animal designator (labeled with letters like “L,” “M,” “Q,” and others) specifies:

• Exactly how many horses, cattle, goats, sheep, poultry, or other animals you can keep
• The number is per legal lot, not per acre
• Enclosure setback requirements for animal housing

Two parcels in Ramona can both be zoned A70, sit on identical acreage, and have completely different animal allowances. If you’re buying specifically for livestock, the animal designator is arguably more important than whether you’re looking at A70 or A72. Always, always pull this information before making an offer.

Agritourism, Overlays, and Other Ramona Restrictions to Watch

Agritourism Under Both A70 and A72

The County’s Agriculture Promotion Ordinance allows agritourism as an accessory use to commercial agriculture in both A70 and A72 zones. Permitted activities include U-Pick operations, on-site tours, agricultural instruction or demonstrations, and classes about agriculture-related topics. You’ll need adequate off-street parking for all employees and customers, no parking on private roads, and no amplified sound.

Horticultural Sales

If you’re running a growing nursery, the retail sale of horticultural and floricultural products requires a Minor Use Permit in all residential and agricultural zones, including A70 and A72.

Ramona Airport Overlay

Many buyers don’t realize Ramona has an active general aviation airport. Properties within the Airport Land Use Compatibility Plan area face additional restrictions on building height, density, and certain uses. If your target parcel sits under a flight path, this overlay can limit what you build.

Environmental and Fire Considerations

Ramona sits in San Diego County’s wildland-urban interface. MSCP (Multiple Species Conservation Program) overlays, steep slope regulations, and floodplain restrictions can further limit clearing and construction. Fire insurance availability and cost have become significant factors for rural Ramona properties in 2026, and I always recommend getting insurance quotes before removing contingencies.

Frequently Asked Questions

Can I build a house on an A70 or A72 parcel in Ramona?

Yes. Family residential use, meaning a single-family home, is a permitted use under both A70 and A72 zoning. You are not limited to agricultural structures only. Many Ramona farm and ranch properties already have a primary residence, and you can also add one guest living quarters per legal lot under both designations.

What is the main difference between A70 and A72 in San Diego County?

A70 (Limited Agriculture) supports crop production and animal keeping with neighborhood-level limits on animals. A72 (General Agriculture) expands the scope to include dairy operations, large-scale farming, and more intensive animal raising. If your plans involve anything beyond a small family farm, A72 typically offers more flexibility.

How do I find out the exact zoning on a Ramona property?

You can request the full zone box from San Diego County Planning and Development Services. The zone box includes your use regulation (A70, A72, etc.), animal designator, development regulations, and any special area overlays. I strongly recommend pulling this before writing an offer.

Does Ramona fall under City of San Diego zoning?

No. Ramona is an unincorporated community governed by the County of San Diego Zoning Ordinance. This is a completely different system from the City of San Diego Municipal Code. Confusing the two is one of the most common mistakes I see buyers make.

Can I run a U-Pick operation on my Ramona farm?

Yes. Agritourism, including U-Pick operations, is permitted as an accessory use to commercial agriculture under both A70 and A72 zoning. You’ll need to provide off-street parking and comply with the County’s Agriculture Promotion Ordinance.

How many animals can I keep on an A70 parcel in Ramona?

The number depends entirely on your parcel’s animal designator in the zone box, not on the A70 use regulation itself. Two A70 parcels can have very different animal limits. The count is per legal lot, not per acre.

Can I operate a dairy on A70 zoned land?

Generally, dairy operations are not permitted under A70 without a Major Use Permit or zone change. A72 zoning is the appropriate designation for dairy farming in San Diego County.

What is the Williamson Act and does it apply in Ramona?

The Williamson Act (Agricultural Preserve Program) provides property tax reductions in exchange for maintaining agricultural use. Properties zoned A70, A72, RR, S90, or S92 are eligible. This can significantly reduce your carrying costs on a Ramona farm or ranch.

Are there building height limits for barns in Ramona?

Yes. Under both A70 and A72, barns and agricultural storage buildings are limited to one story and 12 feet. Buildings up to 24 feet are allowed if they meet main building setbacks. Maximum floor area scales from 1,000 sq ft (under 1 acre) to 5,000 sq ft (larger parcels).

What about the Ramona Airport? Does it affect my property?

Potentially, yes. The Airport Land Use Compatibility Plan applies to properties within the Ramona Airport influence area. This overlay can restrict building height, density, and certain land uses. Check whether your target parcel falls within this zone before making decisions.

The Bottom Line

Buying a farm or ranch in Ramona is one of the most rewarding moves you can make in San Diego County, but only if you go in with clear eyes. The difference between A70 and A72 zoning can determine whether your agricultural vision is fully supported or requires costly permits and workarounds. Layer in the animal designator, airport overlays, environmental restrictions, and fire insurance realities, and you start to see why having experienced guidance matters.
