Willow Glen, San Jose: Homes, History and Local Rules

By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.

Willow Glen is a neighborhood of the City of San Jose, southwest of downtown, that was briefly its own incorporated city from 1927 until San Jose annexed it in 1936. Its older residential blocks, the shops along Lincoln Avenue and two of the city’s seven conservation areas, North Willow Glen and Palm Haven, give it a different set of buying and remodeling questions from much of San Jose.

Because Willow Glen has been part of San Jose since 1936, a sale here follows San Jose rules: the city’s transfer tax and Measure E, its historic conservation areas, its rent ordinance for older apartment buildings and its zoning code. This guide covers what is verified as of October 2026 about the history, housing, local rules, flood exposure and selling. For the wider city, see our San Jose real estate guide, and for the county picture, our Santa Clara County guide.

From small city to San Jose neighborhood

The San Jose Public Library’s archives trace the area’s identity to the Willow Glen School district, established in the 1860s. According to the library, residents incorporated the independent City of Willow Glen in 1927 to resist a Southern Pacific Railroad plan to run track through the area. The city lasted nine years; San Jose annexed it in 1936, which the library ties to access to municipal services.

The library now describes Willow Glen as one of San Jose’s heritage neighborhoods. For a buyer, that history helps explain why building ages and lot patterns vary from block to block, and why historic review can come up when you plan to expand or replace a house.

Homes and housing eras

Expect a range of building ages and property types. Ages can change from one block to the next, so read the assessor’s year built and the permit history for each property rather than relying on a listing’s description.

The city’s own descriptions of two conservation areas give a sense of the older blocks:

North Willow Glen Conservation Area. South of Interstate 280, between the Guadalupe River, Willow Street and Bird Avenue. The city describes it as mostly small-lot residential property developed in the first half of the twentieth century, reflecting growth beyond the original city’s southwest edge between 1885 and 1955. It includes a small neighborhood west of Bird Avenue known as Gregory Plaza.
Palm Haven Conservation Area. Bounded by Riverside Drive, Bird Avenue and Coe Avenue, with homes dating from about 1910 and from the 1930s and 1940s, a layout the city calls notable for its design. The city says many of the houses were designed by architects, and city heritage trees, mostly Mexican fan palms planted around 1913, line its streets.

Older houses bring the usual inspection list: original foundations, knob-and-tube or older wiring, clay sewer laterals and additions of uncertain permit status. Pre-1978 houses also carry the federal lead-based paint disclosure. Our home inspection guide explains which specialist inspections are worth adding.

Lincoln Avenue and the Willow Glen Trestle

Lincoln Avenue is Willow Glen’s main commercial street. The City of San Jose reported in February 2025 that Willow Glen is one of the city’s three business improvement districts that predate 2024, with funds managed by the Willow Glen Business Association. The city says those funds have paid for sidewalk cleaning, planters, light post banners, murals and sculptures along Lincoln Avenue, and 21 LED light strings that brought more evening foot traffic.

The neighborhood’s best-known trail story is the Willow Glen Trestle, a wooden railroad bridge built in 1921 that crossed Los Gatos Creek just east of Lincoln Avenue. The Cambrian Resident reported in January 2021 that, after a seven-year legal fight over restoring it, the trestle was demolished and replaced by a steel pedestrian bridge linking the Three Creeks Trail with the Los Gatos Creek Trail. The paper put the final contract at about $2.49 million.

Historic review, zoning and remodels

San Jose lists seven conservation areas: Guadalupe/Washington, Hanchett and Hester Park, Market-Almaden, Martha Gardens, Naglee Park, North Willow Glen and Palm Haven. It separately lists seven city landmark historic districts, none of them named for Willow Glen. Individual buildings can also be on the city’s historic inventory.

The city’s district page doesn’t spell out what a conservation area means for an owner, so ask the Planning Division before you buy a house you plan to expand or replace. Ask three things: whether the parcel is in a conservation area or on the inventory, what design or historic review applies to the work, and what the base zoning district allows.

The answers also decide whether state housing laws help. Our SB 9 lot split guide explains that a parcel in a historic district or on a historic resource list falls outside SB 9, and our ADU investment guide covers second units. Whether a San Jose conservation area triggers that exclusion is a question for the city, in writing.

Flood exposure: Guadalupe River and its creeks

Willow Glen sits between the Guadalupe River and Los Gatos Creek, so flood status is a real check. Valley Water’s Upper Guadalupe River Flood Protection Project covers about 5.5 miles of channel in San Jose from Interstate 280 to Blossom Hill Road, including parts of Ross and Canoas creeks. Valley Water says a 1995 flood damaged more than 150 homes in the Gardner, Willow Glen and South San Jose areas.

The full project would give 1% (100-year) protection to about 6,280 homes, 320 businesses and 10 schools and institutions. As of Valley Water’s August 2026 update, federal funding has ended, Valley Water is exploring a locally funded path, and design and construction of Reaches 7 through 11 remain on hold. Its locally funded work between the railroad crossings near Willow Street and Padres Drive reduces damage but does not provide 1% protection by itself.

For a specific house, look up the parcel on FEMA’s Flood Map Service Center, read the flood entry on the natural hazard disclosure, and get a flood insurance quote if a lender will require one. Ask the seller about any past water in the crawlspace or garage.

Utilities. San Jose is served by more than one water retailer, so confirm the provider from the seller’s bills rather than assuming one. Ask, too, about the sewer lateral’s age and any repairs, since an older clay lateral is a common inspection finding in older houses.

Transfer tax and rent rules

Transfer tax. A sale in San Jose pays Santa Clara County’s $1.10 per $1,000 and the city’s $3.30 per $1,000. Measure E, approved by San Jose voters on March 3, 2020, adds 0.75%, 1% or 1.5% of the entire price on higher-value sales. The sources disagree on where it starts: the city’s page says transfers of “$2 million or more,” while Old Republic Title’s Santa Clara County manual and other title guides start the first tier at $2,300,000.01. If your price could fall between those figures, ask escrow which threshold applies on your closing date. Our guide to Santa Clara County city transfer taxes shows the tiers and worked examples.

Rent rules. San Jose’s Apartment Rent Ordinance covers apartments in buildings of three or more units built and occupied before September 7, 1979, limiting increases to one 5% increase in 12 months. The city exempts single-family homes, ADUs and in-law units, duplexes, condominiums and townhomes. A Willow Glen fourplex from the 1950s is likely covered; a single-family house with an ADU is not, though state law may still cap its rent. Our San Jose rent ordinance guide for investors covers the ordinance, just cause rules and the registry. Diamond works with multifamily investors in San Jose; see our investor services.

Selling a home in Willow Glen

Buyers compare Willow Glen houses on age, lot, condition and remodel potential. A restored older house in a conservation area and a newer or rebuilt house appeal to different buyers, so price from sales of similar homes nearby rather than a citywide figure. Before listing:

Confirm historic status. Ask Planning whether the parcel is in a conservation area or on the inventory; buyers planning additions will ask.
Collect permits. Pull finals for additions, garage conversions and ADUs, and decide how to handle anything unpermitted. Our guide to selling with an unpermitted ADU covers the options.
Order inspections early. A pre-listing inspection and pest report let you fix, price or disclose items before buyers find them.
Prepare flood papers. The natural hazard disclosure report and any flood insurance or elevation records.
Estimate transfer tax. Especially if the price is near the Measure E line. Title company sheets show different customary splits for the county and city taxes, and they are negotiable, so write the split into the contract.
For rentals, assemble leases, rent history and any registry filings for buyers’ review.

Our Santa Clara County selling guide covers the rest of the process.

This guide is general information, not legal or tax advice. For a specific Willow Glen property, confirm historic status and zoning with San Jose Planning, and ask a California real estate attorney about rent ordinance or contract questions.

Questions people ask

Is Willow Glen its own city?

Not anymore. Willow Glen incorporated in 1927 and was annexed by San Jose in 1936, so today it is a San Jose neighborhood and city rules apply.

Is Willow Glen a historic district?

Not as a whole. San Jose lists North Willow Glen and Palm Haven among its conservation areas, and individual buildings can be on the city’s historic inventory. Ask Planning about a specific address.

What transfer tax applies to a Willow Glen sale?

The county’s $1.10 per $1,000 plus San Jose’s $3.30 per $1,000, and Measure E at 0.75% to 1.5% of the whole price on higher-value sales. The start point is listed as $2 million by the city and $2,300,000.01 by title company guides.

Is Willow Glen in a flood zone?

Some parcels may be. The neighborhood lies along the Guadalupe River and Los Gatos Creek, and Valley Water’s upper Guadalupe flood project is not complete. Check FEMA’s map for the parcel.

Does rent control apply to Willow Glen rentals?

Only to apartments in buildings of three or more units built and occupied before September 7, 1979. Single-family homes, duplexes, condos and ADUs are exempt from the city ordinance, though state law may apply.

What happened to the Willow Glen Trestle?

The 1921 wooden railroad trestle over Los Gatos Creek was demolished after a long legal fight, and a steel pedestrian bridge connecting the Three Creeks and Los Gatos Creek trails opened in its place in January 2021, according to the Cambrian Resident.

Can I build an ADU or split a lot in Willow Glen?

Often an ADU is possible, but historic status and zoning matter. A parcel in a historic district or on a historic resource list is outside SB 9, so confirm the parcel’s status with the city first.

If you’re considering Willow Glen, we can check the parcel’s historic status, flood map and transfer tax before you write an offer, and compare it with nearby Cambrian Park or Campbell. Selling? Start with a home valuation.
