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.

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. 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.

SECTIONS - DETAILS:

1. Each dwelling unit should have an individual 3-foot clear space (including the roof projections) known as the fire separation distance for reducing fire spread to nearby buildings. Provide one-hour fire-resistive construction at the underside of the roof overhang near the primary dwelling in compliance with IBC Table 721.1(2)).
2. Clarify the placement of ceiling/roof insulation for determining the need for attic ventilation, R806. Attic space outside of the thermal barrier requires a ventilation calculation for showing the attic vent opening size using 1 to 150 of attic area in compliance with R806.2 or an unvented roof assembly requires an air-impermeable rigid insulation material with a minimum R-5 value applied correctly to either side of the roof sheathing, R806.5. Show a roof design with insulation types and minimum thickness for meeting the condensation control requirement and the minimum total insulation value of R-38.

MECHANICAL PLANS:

1. Provide (an HVAC system with fresh air intake) whole-house mechanical ventilation with controlled exhaust, R303.4; N1103.6 & M1505.4. 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.
