Off-Street Parking Standards for the T3N: Transect 3 Neighborhood District
In the City of Mesa, the T3N: Transect 3 Neighborhood district requires a minimum of one off-street parking space per residential unit. All residential parking in this district must be positioned at least five feet behind the building's primary façade and may be accessed via an alley, side street, or front, provided that front access is only utilized when no adjacent alley or side street is available [Section 11-58-4, Section 11-58-12].
Residential Parking Requirements
The City of Mesa classifies the T3N district as a walkable, predominantly single-family neighborhood. While the district primarily supports single-unit houses, it also permits various multi-family housing types such as duplexes and mansion apartments [Section 11-59-4].
The following table outlines the specific standards for residential off-street parking in the T3N district:
| Standard Component | Requirement in T3N District |
|---|---|
| Minimum Required Spaces | 1 space per unit [Section 11-58-4, Table Note 7] |
| Minimum Front Setback | 20 feet [Section 11-58-4] |
| Minimum Side Street Setback | 15 feet [Section 11-58-4] |

- On-Street Credit: In the T3N district, on-street parking spaces located immediately adjacent to the lot or parcel may be counted toward the minimum required off-street parking [Section 11-58-12(D)(1)].
Commercial and Civic Parking Requirements
The City of Mesa T3N district is "predominantly single-family" and prohibits most standard commercial uses, such as general retail or offices. However, it does permit certain civic and community uses [Section 11-58-4]. For permitted non-residential uses, the City of Mesa defaults to the parking ratios established in the general development regulations [Section 11-32-3].

|---|---|
| Library or Museum | 1 space per 250 square feet used for public assembly [Section 11-32-3] |
