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:

An independent dwelling (ADU) requires fire spread and utility (electrical & water) separation so that one dwelling is not dependent upon another for water or electrical service.

Each dwelling unit with kitchen requires a separate Pima County assigned street address after Zoning approval, R319.

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

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.
