05/16/2025 Addressing Validation REQUIRES RESUBMIT ATTENTION: Parcel/addressing issue. The site plan shows to be for a second unit ADU. The location does not have units attached to the address and does not appear to be associated with a parcel. Please contact Pima County Addressing at addressing@pima.gov or 520-724-9512 to verify and add the units. After address/units have been added or verified you'll need to submit an address change request to update this record along with a new aerial/site plan that shows the corrected addressing.

06/17/2025 Design Review - Standard REQUIRES RESUBMIT Work visible from the Right-of-Way requires design review, as this project is within the Jefferson Park Neighborhood Preservation Zone. The design manual can be found here:
https://www.tucsonaz.gov/files/sharedassets/public/v/1/city-services/planning-development-services/documents/jefferson_park_design_manual_final.pdf

This project will require a DDO (Design Development Option) for the reduced street-side setback - it would be prudent to wait until other zoning comments are addressed before submitting a design package. A pre-application meeting with the Design Professional, requested through TDC Online, is required prior to your design review application.
