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 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. A dwelling unit providing complete independent living facilities requires compliance with design ordinances for handicap provisions, solar water, photo-voltaic and gray water preparations. Design Ordinances adopted by the City of Tucson. 2. Show compliance with the Inclusive Home Design Ordinance adopted by the City of Tucson Ordinance #10463 on 10/16/2007. Notate an accessible door with a maximum ½" threshold height, minimum door width, changes in floor elevation, door hardware, electrical outlet reach range, grab bar reinforcement, etc. 3. 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. 4. 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. 5. dwellings must provide gray water utilization or preparation, Ordinance #10579/11089 revised July 9, 2013. One story dwellings must have a gray drain line discharge. Additional gray fixture drains are optional. Show a second clothes washer standpipe plumbed to an exterior wall above grade, or a bathing fixture drain looped 3' beyond an exterior wall below grade before connection to the building drain. See details at http://pdsd.tucsonaz.gov/files/pdsd/codes-ordinances/Grey_Water_Options_FINAL_.pdf . FOUNDATION PLANS: 1. Notate the grade away from foundations with a minimum 6" fall within the first 10', R401.3. FLOOR PLANS: 1. Show a maximum ½" floor elevation change at a notated accessible route entrance on the floor plan, R106.1.1. 2. Show the door from a garage to dwelling with self-closing and self-latching provision, R302.5.1. 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. 2. Show the weep screed with a minimum clearance 4" above grade or 2" above paved areas, R703.6.2.1. Update detail #5/4. PLUMBING PLANS: 1. The City of Tucson adopted the 2012 IRC with amendments on 1/1/2012. Remove the UPC code reference on the plans. 2. Show hot water pipe with minimum R-3 insulation, N1103.4.2. 3.

Two possible methods of compliance are: provide one under floor gray drainage plumbing connected to the building sewer line at a point 3' from the foundation; or show two clothes washer standpipes with one discharge opening plumbed through an exterior wall with an above grade stub-out for gray water surface distribution. 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. 2. Provide return air duct and register sizes meeting minimum requirements of 72 SQ IN/ ton, M1403. Minimum duct/register size: heat pump or air conditioner - 6 SQ IN per 1,000 BTU (1 ton cooling = 12,000 BTU). The 5 ton unit requires a minimum 22" diameter return air duct. 3. Show the kitchen exhaust fan minimum 100 CFM rating, M1507.4. ELECTRICAL PLANS: 1. Revise the electrical load calculation showing a minimum 3,800 volt-ampere or 16 A continuous load entry for future Photo Voltaic equipment. 2. Protect all interior 15A & 20A proposed outlets (except garage, kitchen, and bathrooms) including receptacles, lights and smoke detectors with combination type arc-fault circuit interrupters, E3902.12. Update the first note with "bedroom" limitation. INTERNATIONAL ENERGY CONSERVATION CODE: 1. Tucson is in climate zone 2B. The simplified prescribed energy values for glazing is U=0.40 and skylights U=0.65. Show the maximum "U" factors of the windows and doors on the plans as well as the solar heat gain coefficient SHGC minimum value of 0.25, N1102.1.
