What does TSA zoning mean in Salt Lake City?

TSA (Transit Station Area) is a form-based zoning district applied near TRAX light rail stations. It regulates building form, height, and street-facing design rather than a conventional use table, and is Salt Lake City's primary tool for transit-oriented redevelopment.

How do I find the zoning for an address in Salt Lake City?

The Planning Division's interactive zoning map shows the base Title 21A district for any parcel, along with whether it falls inside a TSA or Form-Based Urban Neighborhood (FB-UN) overlay, which control over the base district where they apply.

Can I build an accessory dwelling unit (ADU) in Salt Lake City?

In most residential districts, yes — a 2021 ordinance update allows ADUs by right in most of Salt Lake City's residential zones, subject to size and design standards, without requiring a separate rezoning.

Salt Lake City, UT zoning map & districts

Salt Lake City zones under Title 21A, administered by the Planning Division, and has spent the last several years actively rezoning around its TRAX light rail system under Transit Station Area (TSA) form-based districts that trade conventional use/density rules for building-form standards near stations. Downtown itself is governed by a tiered D-1 through D-4 district system with escalating height and FAR allowances toward the core, and infill-focused Form-Based Urban Neighborhood (FB-UN) districts have been applied in redeveloping areas like Central Ninth and the Granary District.

Salt Lake City's Planning Division publishes an interactive zoning map (ArcGIS-based) for parcel-level lookup, and the Zoning Ordinance text, including the Chapter 21A.33 use tables, is available through the city's code library.

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 Salt Lake City

Citywide, accessory dwelling units are allowed by right in most residential districts following a 2021 ordinance update, which is a routine density lever for infill sites that doesn't require a rezoning. Developers should check both the base district and any TSA or FB-UN overlay, since the overlay's form-based standards typically control over the base district's conventional use table.

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.
