St. Paul’s Catholic School plans $13.6M new campus in Nampa

St. Paul’s Catholic School in Nampa has applied to build a new campus next to St. Paul’s Catholic Church at 515 W. Blaine Ave. BoiseDev reports the proposal is now under review by City of Nampa staff.

This stands out because BoiseDev says St. Paul’s is the only private Catholic school in Canyon County. The planned campus would move the school a little more than a mile from its current location.

What’s proposed

According to permit documents cited by BoiseDev, the project would include a new school and catechetical center for preschool through eighth grade.

Key details in the application include:

• Project value: about $13.6 million
• Building size: 33,359 square feet
• Height: 26 feet
• Stories: one
• Maximum occupancy: 1,119 people

BoiseDev also noted that a rendering video released in January 2025 by Lombard Conrad Architects showed a two-story version of the project. The current permit information, though, describes a one-story building.

Where it would go

The proposed site is at 515 W. Blaine Ave. in Nampa, next to St. Paul’s Catholic Church. BoiseDev reports that location is just over one mile from the school’s current campus.

For families already connected to the school, that means the new building would stay in the same general part of Nampa rather than shifting to a different side of town.

What happens next

Right now, the application is still in staff review with the City of Nampa, according to BoiseDev. No hearing or formal approval date was listed in the notes reviewed.

BoiseDev also reported that St. Paul’s Facebook page says construction is anticipated to begin before the start of 2027 and last about 14 months. That timeline appears to be the school’s expectation, not a confirmed city construction start.

Why it matters locally

A school project of this size can be meaningful for nearby neighborhoods even before work starts. In practical terms, it is a sizeable institutional building tied to an existing church property, and it would create a newer facility for students from preschool through eighth grade.

For buyers and owners nearby, the main things to watch are straightforward: whether city review changes the plan, when construction is approved to begin, and how the final building compares with earlier concepts.
