PLAN REVIEW COMMENTS

Plan review for the above referenced structure has been completed. This letter reflects comments to be addressed. Provide a separate Comment Response Letter when submitting updated plans. Facilitate 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 revisions.

SCOPE OF REVIEW:

The scope of this plan review includes architectural, plumbing, mechanical, energy conservation and electrical compliance with 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.

PROVIDE A COMPLETE PLAN SET showing all proposed alterations to the building with 2018 code compliance.

Place the 2018 IRC reference code on sheet T1.0 rather than 2024 IRC because the permit was initiated before January 1st. The 2024 IRC will require addition electrical items that are missing from this plan set.

Remove the “Carport Conversion” from the title and plans for this permit which is for the ADU. These plans do not clearly show that the Carport Conversion is on a separate permit. The Carport Conversion is to proceed on permit TC-RES-1225-06221 and requires a separate submission.

Provide a separate response letter addressing each comment with location of change on the plans.
