San Carlos Northeast Area Plan: Housing, Makers and Creek Connections in One District

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

San Carlos adopted a new framework for its Northeast Area in June 2026, effective July 22. The plan addresses a district where industrial businesses, research activity and future housing must fit together, rather than replacing the whole area with a single type of use.

For a homebuyer following the east side, that mixed character is the important story. The plan describes both growth and the continuing place of existing businesses. Its relevance to a particular home depends on where that home sits in relation to the district and its connections.

Locate the district before interpreting its scale

The city’s official plan website records adoption on June 8, 2026. The final July 2026 plan describes an approximately 145-acre area between Highway 101, the Caltrain tracks, Belmont Creek and the Greater East San Carlos neighborhood.

Those boundaries help distinguish the Northeast Area from other east-side initiatives. A proposal within this district should be read through its actual location and land-use designation, rather than treated as a citywide change to every residential street.

The projection includes more than housing

The final plan’s 20-year development table includes 1,890 residential units alongside research and development, manufacturing, light industry, offices, retail and utilities. The research-and-development component is substantial, but it is one category within a broader employment district.

This matters to the neighborhood narrative. A mixed district can contain different daily patterns: business deliveries, employees arriving, residents returning and people using public space. Understanding the planned mix gives a more realistic picture than describing the entire area only as new housing or only as a life-science campus.

Makers are part of the stated design

The plan preserves existing permitted uses in specified industrial districts and calls for small-scale manufacturing space on selected ground floors. It also describes retail at major gateways and active uses along corridors.

These details show how building design can support the district’s economic identity. A ground floor used for manufacturing works differently from a residential lobby or a storefront. For a nearby buyer, the immediate frontage and operating context will be more informative than the district’s headline unit count.

Belmont Creek supplies a different kind of connection

The plan envisions a multi-use trail along Belmont Creek, together with publicly accessible paseos. The creek therefore appears as both a natural feature and an organizing element for future movement and open space.

A proposed connection can help explain the long-term vision while remaining distinct from a route that can be used today. Follow implementation at the level of the relevant project: funding, design and construction determine when an individual piece becomes available.

The creek’s drainage role also deserves its own attention at a particular property. A planned public trail does not establish a home’s elevation, flood exposure or insurance needs. Those questions should use the actual parcel and current applicable information.

Consider the district at the scale of a normal day

For someone attracted to an east-side location, identify the trip from the home to the station, shops and other regular destinations. Look at crossings and entrances as well as the straight-line distance. An improvement inside the plan area may serve some routes more directly than others.

A longer ownership horizon can make the district’s direction relevant, but the existing home must still meet the buyer’s current needs. Accommodation, condition, private outdoor space and ongoing costs remain central to the comparison.
