PROJECT: TC-RES-0226-00986 – Residential Building – To install two pre-fabricated carports
2359 E 18TH ST TUCSON, AZ 85719 (R-2 Zoning)
Site Plan Review – 1st Review

TRANSMITTAL DATE: March 13, 2026

This site is in the R-2 Residence Zone (UDC 4.7.9). A single-family residence is a permitted use in this zone (Table 4.8-2) subject to Use Specific Standards 4.9.7.B.6, .9, & .10.

Plan review for the above referenced two pre-fabricated carports has 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: The site plan provided is incomplete.

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. Property line lengths are incorrect. Update per the county website https://onbase.pima.gov/publicaccess/DS_NextGen_Single/etc/cq/results.html?cqid=240&OBKey__552_1=44097

B. 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).

C. Draw and label E 18th St.

D. Provide R-2 zoning labels on all four sides of this parcel (including this parcel).

E. Include the missing 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”

As currently shown, the carport is shown exceeding this allowance by 6’-6” (3’-6” from property line)

Two options exist:

A. Move or shorten proposed carport length (north, toward residence) to achieve 10’-0” distance from south property line.

B. Leave as-is and attempt to secure relief from this standard through 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:

https://www.tucsonaz.gov/Departments/Planning-Development-Services/Planning-Zoning-Applications/Zoning-Administration#section-3

To submit a DDO application, apply for a new sub-record under this permit at TDC Online.

https://www.tucsonaz.gov/files/sharedassets/public/v/2/pdsd/documents/tdc-faq/new-pdfs/sub-records.pdf

See below for more information on the DDO process.

3. COMMENT: Per TABLE 6.3-2.A of the UDC (referenced below), the perimeter yard setback(s) along the west property line(s) is 5’-0”. The proposed carport furthest west, is currently setback 18” off the west property line. There are three options:

A. Locate the carport out of the setback.

B. Distance is 1’-0” or more or 1-0” OR Less (encroaching in setback):
Secure a neighbor setback waiver (provided below) signed and dated by the property owner(s) to the west using this sample provided below;

(Neighbor Waiver Sample – COPY AND PASTE ALL WAIVERS ONTO SITE PLAN EXACTLY AS SHOWN BELOW):

My Name is __________________ and I am the owner of the property located at
________________________. I have reviewed the site plan, and I have no objection to structure being located or constructed ______ feet from the property line as depicted on the site plan.

Signature: _______________________ Date:___________________________

Mi hombre es ________________ y yo soy el dueño de la propiedad ubicada en la _____________________. He revisado el plan y no tengo ninguna objeción a que estructura se encuentra o construye ____________ desde la línea de propiedad, como se muestra en el plan.

Firma: _________________________Fecha:__________________________

C. Distance is 1’-0” or more from property line AND unable to obtain neighbor waiver: If unsuccessful in the attempt to retrieve the neighbor waiver, there is a Design Development Option (or DDO) which affords an attempt to seek relief from the setback requirements.

Know 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:
