Engineering Comments:
1. This site resides within a FEMA AE floodplain and will require the submission and approval of a floodplain use (FPU) permit. The FPU permit is a separate permit that can be submitted within the "sub-records" tab of this associated building permit through TDC online.
2. The FPU permit submission will require the submission of a cost estimate form. A cost estimate of both materials and labor will be required from the contractor responsible for the project. It will break down the total cost into separate lines, separating labor, materials/equipment, and warranties/fees associated with the project. Ensure to have company/contractor letterhead on the document for proper documentation. This cost estimate will be used for substantial improvement calculations.
3. Final Site Engineering approval for permit TC-RES-0226-00531 requires approval of associated submitted FPU permit and resubmission of this permit after approval with matching plans (if modified).

02/13/2026 Residential Zoning REQUIRES RESUBMIT PDSD TRANSMITTAL

FROM: Jeffrey W. Cassidy, Planner
Planning & Development Services Department – Current Zoning Review Section

PROJECT: TC-RES-0226-00531 – Residential Building – Finish 2nd story storage space
4864 E HAWTHORNE ST TUCSON, AZ 85711 (R-1 Zoning)
Site Plan Review – 1st Review

TRANSMITTAL DATE: February 13, 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 single-family residence 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: Regarding scope clarification for this permit: The drawing package, repeatedly throughout the drawings, clearly states “PHASE 1 – 2nd Story Shell only, No utilities, No access from first floor.” However, per google street view this phase appears to have already been completed, unpermitted. Additionally, the drawings clearly show the need for utilities (bathroom) and stairway access. Clarify scope specifically and update drawing labels if what is currently communicated is outdated for this permit.

2. 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. Draw, label and dimension all setbacks. Setbacks for side and rear property lines are 5’-0” flanking the south and west property lines. The front yard setback is 20’-0” (north or east property line). The street side yard setback is 10’-0” (north or east property line). In the case of a ‘corner lot’, like this example (fronting on two streets), the property owner can choose which is which. Update plan and associated content accordingly. Additionally, include this in the required comment response letter.

C. Refer to Pima County’s website https://gis.pima.gov/maps/detail.cfm?&parcel=127051640 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.

D. Draw, label and dimension all property lines, (provide property line lengths) and the shared 10’-0” utility easement to be reflective of information on Pima County’s website. Refer to Pima County’s website https://gis.pima.gov/maps/subdiv/select.cfm?null=&bkpg=07082. 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.

E. 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).

F. 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/12705/1640.pdf . Include any unpermitted additions, modifications and label.

G. Draw and label front E Hawthorne St and N Arcadia Av.

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

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

J. All the drawings provided are missing drawing scales. Provide the scale these drawings are drawn to so reviewers can accurately measure for compliance. For example. The elevation and section drawings need to accurately depict compliance with 25’-0” maximum building height allowed in this R-1 zone. Height is measured per UDC 6.4.4.A. https://codelibrary.amlegal.com/codes/tucson/latest/tucson_az_udc/0-0-0-5131
