San Jose's 6 Historic Landmark Districts: What Property Owners Should Know Before Renovating

San Jose’s 6 City Landmark Districts

San Jose maintains six City Landmark Districts, each representing a distinct chapter of the city’s development. These are the areas with the strictest local historic preservation review. If your property falls within one of these boundaries, any exterior work requires a Historic Preservation permit before you can proceed.

The city also has over 200 individual City Landmarks, several National Register Districts, and seven Conservation Areas. But the six Landmark Districts are where property owners most frequently encounter the HP permit process, so understanding them is the first step in planning a renovation.

Hensley Historic District

The Hensley Historic District sits northeast of downtown San Jose, roughly bounded by East Julian Street, North 1st Street, North 7th Street, and East Empire Street. Named after Samuel J. Hensley and Helen Mary Hensley, who established residency in the area in 1853, this neighborhood contains 279 properties with homes constructed primarily between 1865 and 1930.

The district holds the largest concentration of Victorian-era residences in the City of San Jose, with architectural styles including Italianate, Queen Anne, Victorian Gothic, Eastlake, Neoclassical, and Dutch Colonial Revival. It was listed on the National Register of Historic Places in 1983 and adopted as a local City Landmark District in 1990.

For property owners, this dual designation means both federal and city-level protections apply. The density of contributing structures and the range of architectural styles make this one of the more closely reviewed districts in the city.

Lakehouse Historic District

The Lakehouse Historic District is generally bounded by West San Fernando Street to the north, State Highway 87 and the VTA Light Rail right-of-way to the east, Los Gatos Creek to the west, and Park Avenue to the south. The district name dates back to the 1800s and early 1900s, when the Guadalupe River was dammed to form a recreational lake in the area between the river and Los Gatos Creek.

The district consists mostly of single-family residential properties constructed between 1885 and 1925. It is notable for a unique concentration of single-story Queen Anne style houses, along with Craftsman and Period Revival homes built in and around the 1891 Lake House Tract.

Reed Historic District

The Reed Historic District occupies an irregular area on the south side of San Jose State University, between East San Salvador Street and I-280, South Fourth and South Ninth Streets. It is named after James Frazier Reed, who purchased 500 acres south of downtown San Jose in the mid-1800s.

The district is significant for residential development from roughly 1870 to 1935, as well as early modern multi-family architecture built after World War II in response to the growth of San Jose State College (now SJSU). The southern portion, near the former Reed School (constructed in 1870, later known as Lowell School), retains much of the original 1870-1935 housing stock, particularly along South Sixth Street south of Reed Street. The district was formally designated as a City Landmark Historic District in 2008.

Custom Home Design and Build currently has a project in the Reed Historic District in the design phase. Working within a landmark district adds layers to the design process, from material selection to review by the Historic Landmarks Commission.

River Street Historic District

The River Street Historic District is located east of North River Street, bounded by the Guadalupe River to the west, North Almaden Boulevard and State Highway 87 to the east, West Julian Street to the north, and River Park to the south.

This 1875-1925 neighborhood was one of the largest concentrations of Italian immigrants in California. The working-class community included not only residences but also commercial properties like the Torino Hotel, Almaden French Bakery, and Prindiville Grocery. Architectural styles in the district include Italianate, Greek Revival, Queen Anne, and Mediterranean Revival.

St. James Square Historic District

St. James Square centers on the 6.8-acre St. James Park in downtown San Jose, the only remaining public square in the Downtown Core Area. The square was mapped in 1848 as part of Chester Lyman’s official survey of the city, though development did not begin in earnest until Trinity Episcopal Church was built adjacent to it in 1863.

The St. James Square Historic District was added to the National Register of Historic Places in 1979. Key landmarks include the post office, Santa Clara County Courthouse, Trinity Cathedral, Sainte Claire Club, and the Corinthian Ballroom. The buildings surrounding the park represent civic design from the 1860s through the 1930s.

The Alameda Historic District

The Alameda Historic District is different from the other five: it is a right-of-way transportation corridor only, and it does not include adjacent buildings or parcels. The district runs along The Alameda from Race Street to I-880.

The Alameda is part of the former El Camino Real (The King’s Highway) from the Spanish colonial period (1777-1822), connecting the Pueblo de San Jose with Mission Santa Clara. Willow trees were planted along the road in 1799; the last one was removed in 1982.

Because this district covers only the roadway and its trees, renovation projects on buildings along The Alameda are not automatically subject to HP review based on this particular designation alone. However, individual buildings along the corridor may hold separate City Landmark status or fall within other overlay designations.

What Triggers an HP Permit in a Landmark District

Under San Jose Municipal Code Section 13.48.210, property owners within a City Landmark District must obtain a Historic Preservation (HP) permit before performing exterior work. The definition of “work” is broad. It includes:

• Construction of new structures on the property
• Alteration of existing exterior elements
• Rehabilitation or restoration of building features
• Demolition, full or partial
• Basic color change on any exterior surface
• New pavement or sidewalks on the property
• Fences and walls, new or replacement
• Any other change to the exterior appearance of a structure

The Historic Landmarks Commission reviews projects against the Secretary of the Interior’s Standards for Rehabilitation and, where applicable, the city’s Your Old House: Guide for Preserving San Jose Homes.

What Does Not Require an HP Permit

Not every project triggers review. The following are generally exempt:

• Ordinary maintenance that replaces deteriorated elements in-kind without changing the building’s external appearance
• Interior work that does not affect the exterior
• Same-color repainting (maintaining the existing color scheme)
• Compliant solar photovoltaic (PV) installations that meet specific state requirements

The key distinction is whether the work changes the exterior appearance of the property. If it does, you need a permit. If you are planning a home remodel or addition in a landmark district, assume the HP permit will be part of your timeline and budget from day one.

City Landmark Districts vs. National Register Districts vs. Conservation Areas

San Jose has three types of historic area designations, and property owners frequently confuse them. Each type carries different review requirements.

City Landmark Districts (Strictest)

The six districts covered in this article. Any exterior work requires a City HP permit. The Historic Landmarks Commission conducts a public hearing for each project. This is a local designation by the San Jose City Council.

National Register Districts

San Jose has several National Register of Historic Places districts, including Alviso, the Downtown Commercial District, and New Almaden. The National Register is a federal designation managed by the National Park Service. Projects in these districts may trigger review under the California Environmental Quality Act (CEQA) or Section 106 of the National Historic Preservation Act, but they do not automatically require a City HP permit unless the property also holds a separate City Landmark designation.

Conservation Areas

San Jose has seven Conservation Areas, which provide a less stringent level of review than City Landmark Districts. These areas recognize neighborhoods with historical character but apply more flexible standards. Conservation Area review is typically administrative rather than requiring a full hearing before the Historic Landmarks Commission.

Understanding which designation applies to your property determines which review process you will follow, how long the review takes, and what standards your project must meet. For a detailed walkthrough of the HP permit process, see our full guide to historic preservation permits in San Jose.

The 2025 Ordinance Amendment: What Changed

In December 2025, the City of San Jose amended the Historic Preservation Ordinance under file PP25-005. These changes responded to practical challenges that had surfaced in recent years, particularly around the Levitt Pavilion litigation, which exposed gaps in how the ordinance handled projects that might be considered detrimental to a landmark or historic district.

Key Changes

New definitions. The amendment added formal definitions for three terms that previously lacked clear guidance in the ordinance: “detrimental,” “historic integrity,” and “substantial alteration.” These definitions give property owners and the Historic Landmarks Commission more precise language when evaluating project impacts.

Override mechanism. Before this amendment, if a project was found to be detrimental to a landmark or historic district, it could only be approved if the applicant demonstrated a hardship. The 2025 amendment created an override mechanism modeled on CEQA’s statement of overriding considerations, allowing the City Council to balance a project’s benefits against its detrimental effects on historic resources.

Clarified findings. The amendment also clarified the findings required for HP permit approval under Section 13.48.240, giving applicants and commissioners a clearer framework for decision-making.

These changes do not weaken protections for landmark districts. They do provide a more structured process for evaluating projects where preservation goals and other community objectives intersect.

How to Check If Your Property Is in a Landmark District

Before starting any renovation project in San Jose, especially in older neighborhoods near downtown, confirm whether your property falls within a designated historic area.

Step 1: Check the City’s online maps. The San Jose Planning, Building and Code Enforcement (PBCE) department provides GIS-based maps showing City Landmark Districts, National Register Districts, and Conservation Areas. The Preservation Action Council of San Jose (PAC*SJ) also publishes historic district maps as a public resource.

Step 2: Search the Historic Resources Inventory. The city maintains an inventory of all designated historic resources, including individual landmarks and properties within districts. You can search by address through the PBCE Planning Division.

Step 3: Contact PBCE Planning directly. If you are unsure about your property’s status, call or email the San Jose Planning Division. They can confirm whether your address falls within a designated district and what review process applies.

Step 4: Factor HP review into your project timeline. If your property is in a City Landmark District, add the HP permit process to your project schedule before you begin design work. The HP permit timeline varies by project scope, but planning for it early prevents costly delays.

San Jose is a Certified Local Government (CLG), meaning the city has a formal agreement with the California State Historic Preservation Office to manage local preservation programs. This gives the city direct authority over its own review process, but it also means the process is thorough.

Planning a Renovation in a Historic District

Renovating a home in a landmark district is not a reason to abandon your project. It is a reason to plan carefully and work with a team that understands the process. The HP permit adds time and design constraints, but property owners complete successful renovations in these districts regularly.
