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.

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

GENERAL COMMENTS :

2. Identify the adjacent room with doorway into the proposed room. Bedrooms require compliant egress to the exterior. Show if the alteration requires a new egress opening from the adjacent room.
