North Tustin is an unincorporated hillside community in central Orange County, California, made up of large-lot custom homes on the foothills above the City of Tustin. It is not part of the City of Tustin. It is governed directly by the County of Orange, which shapes everything from zoning to who answers a service call.
The appeal is straightforward. You get bigger parcels, mature trees, hillside views, and in several pockets the right to keep horses, all within a short drive of the job centers and freeways of central Orange County. That combination is rare this close to the coast, and it is the reason North Tustin holds a reputation as one of the county’s more established, higher-priced enclaves.

North Tustin sits in the foothills northeast of Old Town Tustin and north of Interstate 5. On a map it reads like an extension of Tustin, but legally it is separate. The community is unincorporated, meaning it has no city hall of its own and instead falls under Orange County jurisdiction.
That distinction is not cosmetic. County zoning, not a Tustin municipal code, controls what you can build and whether you can keep animals. County services, not city departments, handle land-use questions. Policing comes from the Orange County Sheriff’s Department rather than a city police force. And because of how postal boundaries were drawn, many North Tustin homes carry a Santa Ana or Tustin mailing address even though the property is neither inside the City of Santa Ana nor the City of Tustin. Buyers relocating from out of state are often surprised by this, so it is worth confirming the jurisdiction of any address before assuming which city’s rules apply.
North Tustin is best understood as a cluster of named hillside areas rather than a single uniform tract. The character shifts noticeably as you move up in elevation and across the foothills.
Lemon Heights is one of the most recognized names in the community. It sits higher in the hills, is known for larger parcels, and includes streets where horse-keeping has historically been permitted under county zoning. Homes here range from mid-century originals to substantial custom rebuilds.
Cowan Heights continues the pattern farther into the foothills. It shares the large-lot, semi-rural feel, with winding roads, hillside topography, and a mix of view lots and more sheltered parcels. Like Lemon Heights, parts of Cowan Heights fall within equestrian-oriented zoning.
Panorama Heights is prized, as the name suggests, for elevation and outlook. The higher positions can deliver long views across the basin. Elevation also means grade, so driveways, access, and slope are real factors to weigh on any given lot.
Red Hill anchors the lower, more accessible side of the community closer to the flatlands and freeways. It tends to offer a middle ground: established neighborhoods with easier commutes and less of the steep hillside grade found farther up.
These areas are not rigid boundaries with signs at every corner. They overlap, and locals sometimes use the names loosely. What matters for a buyer is that price, lot size, view, grade, and zoning all vary meaningfully depending on which pocket you are in, and even from one street to the next within a pocket.
Expect variety, not a template. Because North Tustin developed over decades as an area of individual custom builds rather than a single master-planned tract, the homes differ widely in age, style, and size. You will find mid-century ranch homes, large traditional custom estates, and properties that have been torn down to the studs and rebuilt into contemporary residences.
The common thread is the lot. Parcels here are generally larger than what you find in the surrounding incorporated cities, which is much of the point. That extra land supports pools, guest quarters, mature landscaping, and in the equestrian pockets, room for animals. It also means more property to maintain, more hardscape and slope to manage, and, on the hillside lots, real attention to drainage and grading.
Pricing sits toward the upper end of the Orange County market. Rather than quote a figure that shifts month to month, the honest framing is this: North Tustin trades at a premium to the flatland neighborhoods around it, driven by lot size, privacy, and the semi-rural character. The Knight Group can pull current comparable sales for the specific pocket and price band you are considering.
It means the County of Orange is your local government. There is no separate North Tustin city council or municipal code. This has practical consequences a buyer should understand before writing an offer.
Land use and permitting run through the county rather than a city planning department. If you plan to remodel, add square footage, build an accessory dwelling unit, or keep animals, the governing rules are county rules. Law enforcement is provided by the Orange County Sheriff’s Department. Some services that an incorporated city would deliver directly are instead handled at the county level or through special districts.
None of this is a drawback on its own. Many owners specifically want the county’s more permissive hillside and equestrian zoning. But it does change who you call, which code applies, and how certain approvals work. When you buy in North Tustin, confirm the jurisdiction and the applicable county regulations for anything you intend to change about the property.
In parts of it, yes. Sections of Lemon Heights and Cowan Heights have historically carried equestrian-oriented county zoning that permits horse-keeping on qualifying lots. This is one of the defining features that separates North Tustin from the surrounding incorporated cities, where keeping horses on a residential lot is generally not an option.
The important caveat is that equestrian rights are parcel-specific. They depend on the zoning designation, the lot size, and county rules about setbacks and the number of animals. A home two doors down from an equestrian property does not automatically share the same rights. If keeping horses is a requirement rather than a nice-to-have, treat it as a contingency: verify the zoning on the exact parcel with the county before you remove conditions. The Knight Group can help you confirm this in writing rather than relying on a listing description.
North Tustin is served by the Tustin Unified School District, which is a significant part of the area’s draw for families. Foothill High School, one of the district’s comprehensive high schools, is located in the North Tustin area and is closely associated with the community.
School attendance is assigned by boundary, and boundaries can be redrawn, so the specific elementary or middle school tied to a given address should be confirmed directly with the district rather than assumed from the neighborhood name. If schools are central to your decision, tell The Knight Group early. We can filter the search around the attendance areas that matter to you and flag any address where the assignment is not obvious.
Central Orange County location is a core part of the value here. North Tustin sits near several major routes, including State Route 55, the Costa Mesa Freeway, and Interstate 5, the Santa Ana Freeway, with additional connections to the wider Orange County freeway and toll-road network to the east.
The trade-off is elevation and street design. The higher hillside pockets are reached by winding two-lane roads, so the last stretch of any commute out of Lemon Heights, Cowan Heights, or Panorama Heights takes longer than the map distance suggests. Red Hill and the lower-lying streets generally offer quicker, flatter access to the freeways. If commute time is a hard constraint, weigh the specific pocket carefully, because the difference between a low lot and a high one can be several minutes of hillside road on each trip.
The setting is the amenity. North Tustin’s foothill position puts open space, regional parks, and trail access close at hand, and the surrounding hills give the community its quieter, greener feel compared with the denser flatlands. Nearby regional parkland and canyon trails support hiking, cycling, and, in the equestrian pockets, riding.
For day-to-day needs, residents rely on the retail, dining, and services of the adjacent cities, including Old Town Tustin and the broader central Orange County commercial areas, all within a short drive. The living pattern here is deliberately residential and low-density: you trade walkable urban amenities for space, privacy, and proximity to nature, then drive a few minutes for shopping and restaurants.
Name the trade-offs before you fall for the views. Three deserve real attention.
Wildfire and insurance. North Tustin’s foothill and hillside terrain places parts of the community in an elevated wildfire-risk setting typical of the wildland-urban interface. That can affect the cost and availability of homeowners insurance. Confirm the specific fire-hazard designation for any parcel and get an insurance quote in writing during your contingency period, not after close. This is one of the most common surprises for buyers moving up into the hills.
Hillside conditions. Slope brings views and privacy, but also grading, drainage, retaining walls, and access considerations. On the higher lots, budget for a careful inspection of the site itself, not just the house. Geologic and drainage questions are worth taking seriously on graded hillside parcels.
Unincorporated services and rules. As covered above, being outside a city changes which government you deal with and which code applies. For most owners this is a feature, but it does require confirming county rules for any renovation, addition, or animal-keeping plan rather than assuming a city ordinance.
Most of North Tustin is established, individually built housing rather than a single new master-planned development, so the community does not read like a modern tract with a blanket homeowners association over every street. Some pockets do have HOAs and others do not, and dues where they exist vary. Confirm the HOA status and any dues for the specific property.
Because much of the area’s housing predates the era of large master-planned communities, the special Mello-Roos community facilities district assessments common to newer Orange County developments are generally less of a factor here than in newer master-planned areas. That said, assessments are parcel-specific, so verify the actual tax bill for any home rather than assuming. Property taxes follow California’s standard framework under Proposition 13, based on assessed value, with any applicable special assessments layered on top. Review the full tax picture on the specific parcel with The Knight Group and your escrow before you commit.
No. North Tustin is an unincorporated community governed by the County of Orange. It is adjacent to the City of Tustin but is legally separate, with county zoning, county services, and Orange County Sheriff’s Department policing.
Postal boundaries do not always match city or community lines. Because North Tustin is unincorporated, many properties carry a Santa Ana or Tustin mailing address even though they are not inside those incorporated cities. Confirm the actual jurisdiction of any address rather than assuming from the mailing city.
On qualifying lots in equestrian-zoned pockets such as parts of Lemon Heights and Cowan Heights, yes. Horse-keeping rights are parcel-specific and depend on county zoning and lot size, so verify the designation on the exact property with the county before relying on it.
North Tustin is served by the Tustin Unified School District, and Foothill High School is located in the area. Attendance boundaries are assigned by address and can change, so confirm the specific schools for any home directly with the district.
Parts of the community sit in the foothills within an elevated wildfire-risk setting typical of hillside and wildland-urban-interface areas. This can affect insurance cost and availability. Check the fire-hazard designation and obtain an insurance quote for any specific parcel during your contingency period.
North Tustin generally trades at a premium to the surrounding flatland neighborhoods, driven by larger lots, privacy, and the semi-rural character. Actual pricing varies by pocket, lot, view, and condition. Ask The Knight Group for current comparable sales in your target area and price band.
Some pockets do and some do not. Because the area is largely made up of individually built homes rather than one master-planned tract, HOA coverage and dues vary property to property. Confirm the status for any specific home.
Broadly, Lemon Heights and Cowan Heights sit higher in the hills with larger lots and equestrian-zoned pockets, while Red Hill anchors the lower, more freeway-accessible side of the community. Price, grade, view, and commute all shift depending on which pocket and street you choose.
North Tustin rewards precision. The difference between a great buy and a costly surprise here often comes down to details that a listing photo will not tell you: whether the equestrian rights actually convey, where the parcel falls on the fire-hazard map, how the hillside grades and drains, which schools the address really feeds, and what the full tax and insurance picture looks like.
