Caldwell, ID zoning map & districts

Caldwell, part of the fast-growing Boise-Nampa-Caldwell corridor in Canyon County, zones under Title 10 of the Caldwell City Code, administered by the city's Planning and Zoning Division. Residential districts (R-1, R-2, R-3) scale from single-family detached through multifamily, and a dedicated Agricultural (A-1) district covers land still in farm use on the city's rapidly urbanizing edges — a designation under continuous pressure for rezoning as Caldwell's growth corridor pushes outward from Nampa.

The code Caldwell Zoning Ordinance (Title 10, Caldwell City Code)

Caldwell zoning map

The Caldwell Planning and Zoning Division publishes the zoning ordinance and an online GIS zoning map; confirm current parcel zoning through the live map given the pace of rezoning along the city's growth corridor.

There is no link to the official map here yet — confirm current district boundaries directly with the Caldwell planning or zoning department.

A published summary is never the authority. The adopted ordinance and the city's official zoning map govern, and both change — verify the district and every standard on your parcel before you rely on it.

How zoning works in Caldwell

Commercial zoning is split between neighborhood-scale (C-1) and general commercial (C-2) districts, and industrial development is divided into light (M-1) and heavy (M-2) districts. Because Caldwell's growth boundary is actively shifting, checking a parcel's current zoning against the city's live GIS map rather than an older static zoning map is especially important here.

The parcel layer lands in the order demand does. Illinois went first because that's where the deals were; the next state is decided by who tells us what they're trying to underwrite. Tell us where you're building and what you wanted to run — you'll hear from us when Idaho opens, and sooner if we need a test parcel.
