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 Zoning and other departmental requirements, conditions and concerns before permit approval.

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 .
a. Show a minimum 300 SF clear solar-ready zone on a roof or framing plan, T103.3. Model plans should show four typical south facing roof surfaces.
b. Label a double breaker space for future Photo Voltaic on the panel schedule opposite end from the main/supply side, T103.9. Breaker location is located.
3. When the clothes washer is not near an exterior wall show a gray water bathing fixture drain looped 3’ beyond an exterior wall below grade before connection to the building drain. See details for compliance https://www.tucsonaz.gov/pdsd/water-energy-conservation

SITE PLAN:
