PLUMBING PLANS:

1. Tucson Water Department limits flow rates for each water meter size in compliance with P2903.7. Show an appropriate (1”) yard pipe for supporting the existing and proposed dwelling units.

03/11/2024 Site Zoning REQUIRES RESUBMIT ZONING REVIEW TRANSMITTAL

FROM: Wyatt Berger
Lead Planner

PROJECT: TC-RES-0224-00797
1924 East 5th Street – R-1
Sleeping quarters and garage (1st Review)

TRANSMITTAL DATE: March 11, 2024

Please resubmit revised drawings with a detailed response letter stating how all Zoning Review Section comments were addressed.

The site is in the R-1 zone (UDC 4.7.8). A single-family residence is a permitted use in the R-1 zone, subject to use-specific standards 4.9.7.B.5-.9.

1. Indicate on the site plan that the proposed additions to the existing residence are submitted under a separate permit application.

2. Remove the porches from the lot coverage calculation as roofed areas, open on at least one side, that are not used for utilities, maintenance, laundry, storage, or motor vehicle parking, are excluded from the lot coverage calculation (UDC 6.4.3.C.1.a).

3. The lot dimensions and lot size provided on the site plan are incorrect. According to the Fairmount Addition subdivision plat (https://www.asr.pima.gov/ParcelData/Map/Arm/MP04/04018.PDF), the lot dimensions are 68’ x 130’ with a total lot size of 8,840 square feet. Ensure the lot coverage calculation is also updated to reflect the correct lot size.

4. The proposed “lounge area” includes a full-size refrigerator and is therefore considered a separate dwelling unit. Per UDC Table 6.3-2.A, a lot size of 10,000 square feet is required for two dwellings in the R-1 zone, unless the second dwelling is considered an accessory dwelling unit (ADU), subject to use-specific standards 4.9.7.B.6, .8, and .9, and 6.6.3.

Please note that TC-RES-0224-00796 proposes a separate “pantry” that includes cooking facilities and three total dwellings on the site. Multifamily development is not a permitted use in the R-1 zone.

Per a Zoning Administrator’s determination dated May 29, 1996, for the construction to not be considered a dwelling unit, the project is limited to having a refrigerator that can fit below a sink counter, a wet bar sink, and no cooking facilities.

5. If the proposed construction is to be considered a sleeping quarters rather than an ADU, demonstrate compliance with use-specific standard 4.9.7.B.7 as the “lounge area” will be considered a bedroom. Based on issued T22CM02133 and TC-RES-0224-00796, eight total bedrooms are proposed on the site.

For any new single-family dwelling in the R-1 zone with five bedrooms, three parking spaces are required. For every bedroom over five, one additional space is required for each bedroom. For all single-family dwellings in the R-1 zone with five or more bedrooms, all parking spaces must be located on-site, either in a side or rear perimeter yard. Parking spaces may not be located in a vehicular use area in any front street perimeter yard. A parking area is not required to be developed to a commercial standard. A dustproof parking surface is required to at least a minimum of two inches of compacted pea gravel. An existing covered residential parking area may be used.

Per UDC 11.4.3, the term bedroom includes all of the following: 1) Any room that is designated as a bedroom; 2) Any enclosed room that has a minimum area of 60 square feet and has an accessibly opening to the exterior of the building in compliance with the International Building Code (IBC), whether termed a studio, family room, study, den, bonus room, or any other name, except for a living room, dining room, kitchen, and bathrooms; and 3) Any room designated as a bedroom for the purpose of any other code requirement.

6. Perimeter yards are based on a measured from the design grade elevation to the highest point of the exterior building wall (UDC 6.4.5.B and Figure 6.4.5-A). Per UDC 6.3-2.A, when a residential use is adjacent to a residential zone, the required perimeter yard is six feet or 2/3 the height of the exterior building wall, whichever is greater, measured from the interior property lines.

Provide elevations measured from the design grade elevation to the highest point of the proposed exterior walls to verify the south and west perimeter yards. As a rear perimeter yard of 2’-0” is proposed as measured from the south property line, Design Development Option (DDO) approval is required to reduce the rear perimeter yard requirement. The DDO application can be found at this link: https://www.tucsonaz.gov/files/sharedassets/public/v/1/pdsd/documents/planning-amp-zoning/ddo_for_setback_and_height_udc.pdf. Contact Georgia.Pennington@tucsonaz.gov if you have questions about the DDO process.

7. Per UDC 6.6.3.E, the total gross floor area (gfa) of all accessory structures shall not exceed 50% of the gfa of the principal structure. Accessory structures less than 200 square feet gfa and accessory dwelling units are exempt from this requirement.

If a sleeping quarters is proposed, a Board of Adjustment variance is required to be granted to allow the gfa of the accessory structure to exceed 50% of the gfa of the principal structure. Contact Mark.Castro@tucsonaz.gov if you have questions about the variance process.

8. The property is a contributing resource to the Sam Hughes Residential Historic District. The rear guest house and carport appear to have been demolished in 2021. The effective date of construction for this structure was 1954. The actual construction date may be earlier.

Buildings, portions of buildings, or structures that are 50 years of age or older must be architecturally documented prior to demolition (UDC 3.12.1). Documentation shall be reviewed and approved by the City Historic Preservation Office prior to Zoning approval of TC-RES-0224-00797.
