Walnut was planned with horse trails threaded behind its hillside tracts, and that semi-rural layout still shows in the lot sizes, the slopes and the easements that cross the city. Most housing is detached and dates from the 1970s onward, which gives property here a different maintenance profile from the older valley cities around it.

Location, Roads and Local Government
Walnut occupies part of the San Jose Hills in the eastern San Gabriel Valley. State Route 60 passes just to the south, Interstate 10 is reached to the north through West Covina, and State Route 57 runs along the east side near Diamond Bar and Pomona. Inside the city, Grand Avenue, Lemon Avenue, Nogales Street, Valley Boulevard and Amar Road, which becomes Temple Avenue, carry most trips. Metrolink’s Riverside Line stops at the Industry station a short drive south, and Foothill Transit runs the local bus routes.
The city incorporated in 1959. It contracts with the Los Angeles County Sheriff’s Department, through the Walnut/Diamond Bar Station, and with the Los Angeles County Fire Department. Mt. San Antonio College sits on the eastern edge of town, with Cal Poly Pomona just beyond it.
School Districts and Utilities by Address
Most of the city is served by the Walnut Valley Unified School District. Streets on the west side fall within the Rowland Unified School District instead, and the line does not follow an obvious landmark, so check the district’s own boundary tool for any address before writing an offer. Water for most homes comes from the Walnut Valley Water District, electricity from Southern California Edison and gas from SoCalGas. The property tax bill is worth reading line by line, since some newer tracts carry landscape, lighting or facilities assessments in addition to the base tax.
Walnut Real Estate by Era
- 1960s ranch houses: the earliest subdivisions, on gentler ground in the central and southern parts of the city, usually single story with attached garages.
- 1970s and 1980s hillside tracts: two-story and split-level houses on terraced pads, often with a slope at the rear and views across the valley.
- Later planned neighborhoods: larger houses from the late 1980s into the 2000s in communities such as Snow Creek and Three Oaks, some with homeowners associations.
- Attached homes: a limited supply of townhomes and condominiums, mostly near the main boulevards.
- Larger lots: scattered parcels where the zoning allows horses or other animals, subject to city standards.
Hillside Lots, Slopes and Trails
Much of the due diligence on houses for sale in Walnut happens outside the walls of the house.
- Slope ownership: find out where the lot line falls on any slope and who waters, plants and repairs it. Some slopes belong to the owner, some to an association and some to a maintenance district.
- Drainage: walk the concrete swales and drains. Blocked or cracked drainage is the usual start of slope damage.
- Trail and utility easements: read the preliminary title report for bridle trail, drainage or access easements along the rear or side of the lot, which limit where walls, pools and additions can go.
- Fire hazard mapping: hillside areas may be mapped in a fire hazard severity zone, with brush clearance duties and effects on insurance. Check the current state and city maps.
- Systems of a certain age: on a house from the 1970s or 1980s, look closely at the roof, plumbing supply lines, heating and cooling equipment, and any pool.
Rail, Freeway and Campus Activity
The southern edge of Walnut meets the City of Industry along Valley Boulevard, where freight rail lines and warehouses run for miles. Homes near that boundary hear trains, and trucks use Valley Boulevard and the 60 around the clock. On the east side, the college generates traffic on Grand and Temple avenues during the academic year and during stadium events. Visit a property at commute hours and in the evening before deciding how much any of this matters to you.
Selling a Home in Walnut
Many sellers here have owned for a long time, and the house may still have original finishes or additions made without permits. Pull the city’s permit history, decide whether to legalize or simply disclose unpermitted work, and consider a pre-listing inspection so repair requests do not come as a surprise. Clean up slopes and drains, since buyers and their inspectors go straight to them. State the correct school district, lot size and any easements in the listing, because those are the facts buyers of this type of property verify first.

Frequently Asked Questions
Which school district serves homes in Walnut?
Most addresses are in the Walnut Valley Unified School District, while part of the west side is in the Rowland Unified School District. Look up the specific address with the districts, because the boundary is not obvious on the ground.
Can I keep horses on a property in Walnut?
Only on lots where the zoning and lot size allow it. Ask the city’s planning staff about the specific parcel and check for recorded restrictions before you buy with animals in mind.
Who maintains the slope behind a Walnut house?
It depends on the tract. The slope may be part of the owner’s lot, association common area or a maintenance district, and the title report, tract map and association documents will show which.
Is there commuter rail near Walnut?
Yes. Metrolink’s Riverside Line stops at the Industry station just south of the city, with service toward downtown Los Angeles and Riverside. Check the current timetable, since service is concentrated at commute hours.
