TRANSMITTAL DATE: 09/30/2025

This site is located in the R-1 zone (UDC 4.7.8). A single-family residence is a permitted use in this zone (Table 4.8-2) subject to Use Specific Standards 4.9.7.B.5 - .9.

RESUBMITTAL OF THE FOLLOWING IS REQUIRED: Correct plans, as noted in the comments below, along with a response letter indicating how all Site Zoning comments were addressed. A list of zoning review items are provided at this link:

1. Buildings, portions of buildings, or structures that are 50 years of age or older must be architecturally documented prior to demolition. Documentation will be reviewed and approved by the Historic Preservation Office before a permit is issued. Demolition (Historic Structures) Application and General Information may be downloaded at www.tucsonaz.gov/files/sharedassets/public/v/1/pdsd/documents/planning-amp-zoning/historic_demolition_application_form.pdf Please submit the completed documentation under the permit number via your TDC online account.

2. The current site plan does not fully address the requirement for ADA access. Per the City of Tucson Inclusive Home Design Ordinance ( https://www.tucsonaz.gov/files/sharedassets/public/v/1/city-services/planning-development-services/documents/inclusivehomedesignordinance.pdf
), all new dwellings have a requirement to provide an “accessible route from public and common areas, including, but not limited to, a driveway or public street or sidewalk”. Please demonstrate an ADA accessible pathway to a public area.

3. Although the site zoning is provided on Provide Sheet A0.00, adjacent zoning is not. Please provide adjacent zoning. For further information regarding plot plan directions, please visit https://www.tucsonaz.gov/Departments/Planning-Development-Services/Permits/Plan-Examples/Plot-Plan-Example .

4. Provide all height dimensions for the screen walls as these are not fully dimensioned on the west and south elevations depicted on Sheet A3.01.

5. Provide dimensions from the west property line to the primary residence and proposed ADU.

6. Provide the dimension of the perimeter setback to the primary dwelling.

7. Provide a dimension from the centerline of E Hawthorne St. to the back of the wedge curb (which is approx. 22’6” ft. per paving plan I-413_004 found at https://maps-and-records.tucsonaz.gov/construction-plans/details/I-413 ) and from the back of the wedge curb to the property line (approx.10ft.).

8. Recalculate lot coverage on Sheet A0.00 by adding the vehicular use areas.

9. Additional comments may be forthcoming depending on responses to zoning review comments and plans submitted for the next review.
