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.

GENERAL REQUIREMENTS:

Separate the submitted files with construction plans and support documents in different files.

Show compliance with the Inclusive Home Design Ordinance adopted by the City of Tucson Ordinance #10463 on 10/16/2007. Notate accessible route, minimum door width, changes in floor elevation, door hardware, electrical outlet reach range, grab bar reinforcement, etc.

Each dwelling unit building and associated construction requires a separate building permit, R319. Submit an application and plan set for the main dwelling porch addition. Remove the porch sheet A100 from this plan set.

PLANS:

1. Notate a cool (white) roof finish as required by the ADU provisions.
2. Show a maximum ½” floor elevation changes at a notated accessible route entrance on the floor plan, R106.1.1. Include all threshold conditions for a route from the exterior into the living space.
3. Provide manufacturer’s calculations and data for pre-engineered trusses dated and wet-sealed by an engineer who is registered in Arizona, or notate the requirement for deferred submittal, R106.1.

MECHANICAL PLANS:

1. Provide (an HVAC system with fresh air intake) whole-house mechanical ventilation with controlled exhaust, R303.4; N1103.6 & M1505.4. Show the minimum airflow rate setting and location of the device requiring this adjustable setting. A two or three bedroom dwelling under 1501 SF requires a 45 CFM continuous setting.

ELECTRICAL PLANS:

1. TEP may require the service panel for the property at the closest building to the service transformer. A service line change or a new meter location must be coordinated with TEP for approval. Show an underground feeder from a metered service panel to the more distant dwelling.
2. Show two or more 2O AMP small appliance circuits at the kitchen countertop receptacle outlets; they may also serve the breakfast room and dining room, but not other locations, E3703.2 and E3901.3.
3. Interior 15A & 20A circuits serving outlet locations (except garage, kitchen, and bathrooms) including receptacles, lights, and smoke detectors require combination type arc-fault circuit interrupters, E3902.16.

01/29/2024 Site Zoning REQUIRES RESUBMIT ZONING REVIEW TRANSMITTAL

FROM: Wyatt Berger
Lead Planner

PROJECT: TC-RES-0124-00056
103 West Michigan Street – R-3
New residence (1st Review)

TRANSMITTAL DATE: January 29, 2024

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

1. The lot coverage calculation provided is incorrect and should include the entire vehicular use area, measured within the outside edges of any area allocated to vehicle use, whether improved or unimproved (UDC 6.4.3.B.3.b and Figure 6.4.3-A). Lot coverage shall not exceed 70% of total lot size (UDC Table 6.3-2.A).

2. A rear porch, attached to the existing residence, appears in aerial photography in 2005. Zoning was unable to determine whether a permit was obtained for this porch. Provide permit documentation for this rear porch with your resubmittal. If a permit was not obtained for this porch, a separate permit is required to allow the construction to remain.

3. Per UDC Table 6.3-2.A, the minimum lot size within the R-3 zone is 5,000 square feet. The Pima County Assessor’s Office indicates that the subject property has a lot size of 4,171 square feet.

Demonstrate compliance with UDC 6.4.2.B.3 by providing documentation that the lot was existing and of record on September 20, 1948, or was legally created under Pima County jurisdiction and of record at the time of annexation.

4. Clarify whether the proposed perimeter yard setbacks are measured from the exterior building wall or roof overhangs. Along interior property lines, roof overhangs may extend two feet into the setback, provided the setback is not reduced to less than three feet (UDC 6.4.5.D.1.b).

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

Based on a wall height under 6’-0”, the required side perimeter yard as measured from the south lot line is 6’-0”; the proposed perimeter yard is 1’-0”.

Based on a wall height of 11’-4”, the required rear perimeter yard as measured from the west lot line is 7’-7”; the proposed perimeter yard is 6’-0”.

Design Development Option (DDO) approval is required to reduce the required side and rear perimeter yards. The DDO application and requirements can be found at: https://www.tucsonaz.gov/files/sharedassets/public/v/1/pdsd/documents/planning-amp-zoning/2019_ddo_for_setback_and_height_udc.pdf. Contact Georgia.Pennington@tucsonaz.gov if you have questions about the DDO process.
