PROJECT: T22CM06176
1405 W Sonora St
ADU (1st Review)

TRANSMITTAL DATE: August 15, 2022

COMMENTS: Please resubmit revised drawings and any redlined plans along with a detailed response letter, which states how all Zoning Review Section comments were addressed.

1. Clarify whether the existing ramada as depicted on the site plan will be removed or not. A neighbor's setback waiver signed by the owners of 1407 West Sonora Street is required to be pasted on the plot plan if the ramada is to remain.

2. Remove any language under "ADU comments" on the plot plan referring to the R-1 zone. These comments do not apply to this project.

3. Per UDC 6.4.4.A, building height is measured from design grade to the highest point of a flat roof. The elevations provided indicate that the height of the proposed ADU, measured from design grade to the highest point of the roof, is 12'-6," which exceeds the maximum 12-foot height requirement (UDC 6.6.3.B.4). A Board of Adjustment variance is required if the height of the proposed ADU is to exceed 12 feet.

If you have any questions about this transmittal, please contact Wyatt Berger at Wyatt.Berger@tucsonaz.gov or 520-837-4951.

PLAN REVIEW COMMENTS

Plan review for the above referenced structure 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.

SCOPE OF REVIEW:

The scope of this plan review covers architectural, plumbing, mechanical, energy conservation and electrical. All code references are to the 2018 International Residential Code and 2018 International Energy Conservation Code. All features were checked only to the extent allowed by the submittals provided. All portions of this project are assumed to meet or will meet other departmental requirements, conditions and concerns before permit approval.

SITE PLAN:

1. Show the location and size of buildings, utility meters and gas, water, electric and sewer or septic lines from property line to building, R106.1.1. Identify the utility lines requiring upgrade or replacement.
2. Show a upgraded 1” line to the existing dwelling. Minimum size for a pipe supplying two bathrooms within the building is 1”, P2903.7.

2. Notate a cool (white) roof finish as required by the ADU provisions.

PLUMBING PLANS:

1. Tucson Water Department limits flow rates for each water meter size in compliance with P2903.7. Show an appropriate yard pipe bypassing the existing dwelling and the water meter size.
