PROJECT: TC-RES-0226-00769 – Residential Building – Awning (Unpermitted Carport) via CE-VIO0126-00218
1635 S SHANNON RD TUCSON, AZ 85713 (R-1Zoning)
Site Plan Review – 1st Review

TRANSMITTAL DATE: March 05, 2026

This site is in the R-1 Residence Zone (UDC 4.7.8). A single-family residence is permitted use in this zone (Table 4.8-2) subject to Use Specific Standards 4.9.7.B.5 - .9 for 1 unit; 4.9.7.B.1 - .9, & .11 for 2 units (min. 10,000 sq ft lot size required).

The City's Unified Development Code (UDC) (Section 1.4.1.C) establishes that before the City issues any approvals or permits; we must confirm that a site complies with UDC standards. Therefore, as part of permit reviews, we review a site's permit history and compare it to aerial photography to confirm that unpermitted work has not occurred. In many cases, this does mean that a homeowner must apply for permits for unpermitted work before we can approve any new work on that site.

Plan review for the above referenced awning (Unpermitted Carport) via CE-VIO0126-00218has been completed. This letter reflects comments to be addressed. For facilitating a shorter back check time, please provide updated plans and calculations with a written response to each of the notated items indicating action taken. Do not cloud the changes made for comment updates; revisions are processed if changes occur after the permit is issued.

1. COMMENT: No site plan was provided.

Provide a site plan that meets the requirements show in the plot plan example at the following link:

https://www.tucsonaz.gov/files/sharedassets/public/v/2/pdsd/documents/plan-samples/basic-site-plan_feb2026.pdf

Specifically:

A. Draw, label and dimension everything that exists on the property to a scalable drawing graphic (examples include the principal residence, porches, breezeways, sidewalks, driveways, parking spots, walls, fences, ramada, shed, carport, shade sail, cistern, pool, guest house, sleeping quarters, accessory dwelling unit) and provide dimensions of any structure as it relates to nearby structures and property lines and provide the heights (measured from above finish grade to top of wall, etc.) of those structures that run parallel-perpendicular to any nearby adjacent property lines. Provide heights at various locations along the fence/wall if applicable.

B. Refer to Pima County’s website https://gis.pima.gov/maps/detail.cfm?&parcel=11803216A to locate and provide the parcel number, legal description, subdivision name, book and page numbers, township-section and range, sequence number on the plot plan.

C. Draw, label and dimension all property lines, (provide property line lengths) and any easements to be reflective of information on Pima County’s website. Refer to Pima County’s website https://onbase.pima.gov/publicaccess/DS_NextGen_Single/etc/cq/results.html?cqid=240&OBKey__552_1=24062 . The math of the property line lengths will produce the total parcel square footage. Be aware that some easements may require referring to the title report of the property (procure at title company if not already in possession. For example, this is especially significant in avoiding building in a utility easement where the provider may need regular access to service. Any need to build within the easement would then require written approval from the utility provider within that easement.

D. A lot coverage calculation table was not provided. Per UDC Article 6.4.3.C.1.a roofed areas, porches, open on at least one side are NOT included in the calculation and per UDC Article 6.4.3.B.3.b Vehicular use areas, measured within the outside edges of any area allocated to vehicle use, whether improved or unimproved are included in the lot coverage.

Calculate (measure) square footage of every enclosed (NOT open structures like a porch, ramada, carport) structure on site and all vehicular use area (driveway, parking, turnaround, backup) and input into lot coverage calculation table. A carport would be calculated under vehicular use area. These separate ‘category numbers’ are added together and divided by the total parcel square footage to produce the lot coverage percentage that demonstrates compliance (or not).

E. Draw, label and dimension the principal residence graphic to be representative of that via Pima County’s website (property record card) https://www.asr.pima.gov/ParcelData/prc/11803/216A.pdf . Include any unpermitted additions, modifications and label.

F. Draw and label S Shannon Rd

G. Provide R-1 zoning labels on all four sides of this parcel (including this parcel).

H. Provide missing site plan scale, corresponding graphic scale and north arrow.

I. If the drawing provided is done by a professional, include the drafter-designer-consultant name, address, license number and contact information on the title block of every sheet.

2. COMMENT: Per TABLE 6.4.5.C.1.a., “For single-family and duplex development, the minimum required street perimeter yard is 20’-0” measured from the street property line”

Additionally, per 6.4.5.D.3.a. “Shade structures or carports may project up to 10’-0” into required perimeter yards. Such architectural features include, but are not limited to, overhangs, moveable insulating walls and roofs, detached solar collectors, reflectors and piping”

No site plan was provided with measurements were provided but will be upon addressing zoning comment #1. Again, a reminder that code enforcement will be verifying if the dimensions provided on the drawings match reality upon doing a site visit. If the carport does not meet the standard above, there is an option to secure relief from this standard thru the Design Development Option (DDO) process.

Be aware this is an extra 6-week review and the neighbors within 100’-0” are made aware of this attempt to seek relief from being in the setback. Zoning will not be able to approve the permit application until the DDO is approved. This information is linked here:
