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:

The City of Tucson adopted the 2018 IRC with amendments and building ordinances for all dwellings.

Clarify if the proposal is for an addition to the existing dwelling (without kitchen) or a new dwelling with kitchen. A living unit with kitchen is considered a dwelling.

Each dwelling unit with kitchen requires a separate Pima County assigned street address after Zoning approval, R319. Show Pima County assigned unit numbers at each dwelling on the site plan. https://www.pima.gov/1010/Addressing-Frequently-Asked-Questions

An impact fee payment is required for an ADU or second dwelling at the time of permit payment.

Provide a response letter addressing each comment with location of change on the plans. Submit separate letter and plan set files.

GENERAL COMMENTS :

1. A dwelling requires a fire barrier between units (duplex) without openings. Provide plans with independent utility connections for each unit.
2. An addition requires the removal of the kitchen. Update the plans showing a wet bar without major appliances.

SITE PLAN:

1. Each dwelling requires an appropriate source of electrical and water supply. Show the location and size of lines with connection points, R106.1.1. Identify the utility lines requiring upgrade or replacement.
2. Each dwelling unit requires fire separation to reduce fire spread to nearby buildings. Show one-hour fire-resistive construction in compliance with IBC Table 721.1(2). Eliminate utilities passing though the separating wall.

PLUMBING PLANS:

1. Show an individual accessible water supply shut off and water heater for the proposed dwelling unit, P2903.9.1.
2. Show the water heater rating, P2801.1.

MECHANICAL PLANS:

1. Provide (an HVAC system with fresh air intake) whole-house mechanical ventilation with controlled exhaust, R303.4; N1103.6 & M1505.4 for the proposed dwelling unit. Identify the device model number providing an adjustable setting and note the minimum continuous setting. A one-bedroom dwelling under 1501 SF requires a 30 CFM continuous setting.

ELECTRICAL PLANS:

1. Update the existing panel schedule showing the breaker connection for the proposed sub panel feeder, E3602.1 & E3603.1.

INTERNATIONAL ENERGY CONSERVATION CODE:

1. Energy Certificate: (Mandatory) place near the indoor furnace or in utility room, N1101.14. Add notation for the proposed dwelling unit.
