PLAN REVIEW COMMENTS

Plan review for the above referenced structure has been completed. This letter reflects comments to be addressed. In order to facilitate a shorter back check time, please provide an updated complete plan set 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 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.

SITE PLAN:

1. Indicate the location and size of buildings, utility meters and gas, water, electric and sewer or septic lines from property line to building, R106.1.1. Show the utility lines requiring upgrade or replacement.
2. Update the Upper Floor Area using exterior dimensions of structure.

SECTIONS - DETAILS:

1. Clarify the placement of ceiling/roof insulation for determining the need for attic ventilation, R806. The space between roof insulation and ceiling may not be vented.
2. 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 or R-30 when extended over the wall top plate for additions under 500 SF.
3. A vented attic space requires a calculation for showing the attic ventilation opening size using 1 to 150 of attic area in compliance with R806.2. Provide appropriate upper and lower space vents when applying the reduced area calculation.

MECHANICAL PLANS:

1. Provide (an HVAC system with fresh air intake) whole-house mechanical ventilation, or controlled exhaust with a calculated airflow rate, R303.4; N1103.6 & M1505.4. Show the system and appropriate flow rate setting on the plans. A four or five bedroom dwelling of 1501 – 3000 SF requires a 75 CFM continuous setting.
