This letter reflects comments to be addressed. In order to facilitate a shorter back check time, please provide two sets of 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 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. Verify that bedroom #2 is accessed through bedroom #3. 2. Consider a shower valve location for bathroom #2. 3. Limit all code references to those recognized by the City of Tucson. Adopted 2012 codes are listed at the Planning & Development Services web site. Remove the 2006 Plumbing code reference on sheet #1. 4. 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. 5. 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. 6. All construction drawings submitted after June 1, 2010 for one- or two-family dwellings must provide gray water utilization or preparation, Ordinance #10579/11089 revised July 9, 2013. Include two clothes washer standpipes at an exterior wall, one with an above grade stub-out, and one plumbed to the building drain. FLOOR PLANS: 1. Show a maximum ½" floor elevation change at a notated accessible route entrance on the floor plan, R106.1.1. 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. PLUMBING PLANS: 1. Show hot water pipe with minimum R-3 insulation, N1103.4.2. 2. Show a provision for solar water preparation in compliance with City of Tucson Ordinance #10549 . 3. The revised City of Tucson Ordinance #11089 for gray water preparation requires a minimum of one compliant fixture with above grade discharge when feasible. A second clothes washer standpipe may discharge to an exterior wall discharge point for immediate usage. See the detail at http://pdsd.tucsonaz.gov/files/pdsd/codes-ordinances/Grey_Water_Options_FINAL_.pdf The diver valve system on sheet #3 does not meet the minimum requirement for usage without additional features. 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. Provide demand calculations in accordance with Manual J/S/D standards, M1401.3, M1601.1. Systems shall be sized in accordance with Manual S based on building loads calculated in accordance with Manual J and duct systems sized in accordance with Manual D. Notate if the mechanical system calculations may be provided by deferred submittal. The deferred calculations must be approved through revision process prior to mechanical inspections. ELECTRICAL PLANS: 1. Add a double breaker space for future Photo Voltaic on the panel schedule. 2. Revise the electrical load calculation showing a minimum 3,800 volt-ampere or 16 A continuous load entry for future Photo Voltaic equipment. 3. Show a smoke alarm in each bedroom and outside in the immediate vicinity. 4. 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 note #x with "bedroom" limitation. 5. Protect extended branch circuits with combination type arc-fault circuit interrupters, or an AFCI type receptacle at the first outlet on the branch circuit, E3902.13. 6. Provide notation requiring tamper resistant receptacles for 125 volt, 15A and 20A receptacles, R4002.14. 7. Show or notate a disconnect means or a locking breaker for the water heater, E4101.5. INTERNATIONAL ENERGY CONSERVATION CODE: 1. The simplified prescribed energy values for glazing is U=0.40, skylights U=0.65, ceiling R=38 and walls R=13. Update the maximum "U" factor of the windows and doors on the plans, and add the solar heat gain coefficient SHGC minimum value of 0.25 at sheet #1, N1102.1. Also, update note #3 sheet #2.
