Mesa T3N District: Transect 3: Neighborhood Setback Requirements
In the City of Mesa T3N: Transect 3: Neighborhood district, the main building must be placed with a front setback between a minimum of 15 feet and a maximum of 25 feet, while maintaining a minimum rear setback of 30 feet. Side setbacks for the Mesa T3N district are generally 5 feet for the building, though parking areas require a larger side setback of 7 feet [Section 11-58-4].
Main Building Setback Requirements
The City of Mesa defines specific placement standards for primary structures within the T3N district to ensure a consistent neighborhood character. These standards include both minimum and maximum "build-to" ranges for street-facing facades.
| Placement Type | Minimum Setback | Maximum Setback |
|---|---|---|
| Front | 15 feet | 25 feet |
| Side Street | 10 feet | 20 feet |
| Side | 5 feet | N/A |
| Rear | 30 feet | N/A |
Exceptions and Modifications
- Alignment with Neighbors: If existing adjacent buildings are located in front of the regulated front setback, a new building in the Mesa T3N district may be set to align with the facade of the most immediately adjacent property [Section 11-58-4(C)].
- Historic Districts: For parcels within an identified historic district in the City of Mesa, the minimum and maximum setbacks are determined by the setbacks of existing buildings along that specific block [Section 11-58-4(C)].
- Duplex Shared Walls: No side setback is required along the common property line between duplex building types within the T3N district [Section 11-58-4(C)].
Accessory Structure Setback Requirements
Accessory structures in the Mesa T3N district, such as detached garages or sheds, have reduced rear and side requirements compared to the primary residence.
| Placement Type | Minimum Setback Requirement |
|---|---|
| Front | 15 feet |
| Side Street | 10 feet |
| Side | 5 feet |
| Rear | 5 feet |
Parking and Driveway Setbacks
The City of Mesa regulates the placement of parking areas separately from buildings within the T3N district to maintain the aesthetic of the streetscape.
| Parking Placement | Minimum Setback Requirement |
|---|---|
| Front Setback | 20 feet |
| Side Street Setback | 15 feet |
| Side Setback | 7 feet |
| Rear Setback | 5 feet |
For parking access, the City of Mesa requires that the front parking access drive width be a maximum of 12 feet [Section 11-58-4(G)]. Similar to building setbacks, if adjacent buildings are closer to the street than the regulated 20-foot parking setback, the Planning Director may allow a new building's parking to align with the neighboring facade [Section 11-58-4(G)].
