SCOPE OF REVIEW:

The scope of this plan review covers architectural, plumbing, mechanical, energy conservation and electrical. All code references are to the 2012 International Residential Code and 2012 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 COMMENTS:

1. All SFR and Duplex plans submitted after March 1, 2009 require a solar water system, or future installation preparation City of Tucson Ordinance #10549 with one of the following provisions: ½"control conduit and two ¾" copper piping for water with rooftop termination; straight 3" capped sleeve; or an accessible attic (clear path 30" wide x 30" high) over the water heater. Show appropriate notation.
2. All SFR and Duplex plans submitted after July 1, 2009 require a solar photo-voltaic system, or future installation preparation City of Tucson Ordinance #10549 with the following provisions: 1. A 4 square feet area for (meter, disconnect & inverter) equipment adjacent to the electrical service panel or near the proposed collector panel space. 2. The best roof space available for accommodating PV solar collector panels with capacity for collector dead loading (typically 4 lbs/SF). 3. A minimum 3,800 volt-ampere PV electrical load entry on the Service Load Calculation (Show as a continuous load of 15.8 A). 4. An Electrical Panel Schedule with a 240 volt circuit breaker space labeled "reserved for Photo Voltaic". See electrical comments.

SECTIONS - DETAILS:

1. 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 (closed cell spray or rigid board tight to the roof sheathing), R806.5. This condensation control provision is necessary for code compliance, and may be a single layer of air-impermeable insulation, or layered with batt insulation for achieving the total required roof R-value. Update sheet S-4 and S-5.

MECHANICAL PLANS:

1. Provide (an HVAC system with) whole-house mechanical ventilation with continuous or a minimum controlled intermittent airflow rate, R303.4 & M1507.3. Show a source of outside supply air or continuous exhaust fan function.
2. Show impact protection for appliances located in the garage, M1307.3.1.
3. Show dryer vent size and location for venting to exterior, M1501.

ELECTRICAL PLANS:

1. Show compliance with the City of Tucson Ordinance #10549 for future Photo Voltaic on the panel schedule.
2. Show or notate the requirement for a carbon monoxide detector outside of bedroom doors, when the dwelling includes an attached garage or gas appliance, R315.
