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. 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. SECTIONS - DETAILS: 1. Provide consistent information for the unvented conditioned attic space, R806. Sheet A.5 shows insulation placement for an unvented attic, although sheet A.7 has venting calculations. 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 (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. Remove the HB notation from the P & T discharge pipe termination. 2. Show hot water pipe with minimum R-3 insulation, N1103.4.2. 3. Provide consistent pipe sizes (diameter), average pressure and a complete fixture unit schedule, P2903.6. Sheet A.0 and P.1 show different yard pipe sizes, P2903.7. 4. A single story dwelling only requires preparation from a single gray-water discharge fixture, Ordinance #11089. Additional gray water plumbing is optional, but may only include tub, shower and lavatory fixtures. Update the plan with appropriate fixtures. 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 supply ducts with minimum R-8 insulation (includes vented attics) except when completely located inside the thermal envelope, N1103.2.1. Update note #9. ELECTRICAL PLANS: 1. Verify the water heater circuit size for serving the load, E3702.11. A whole house tankless water heater may require a larger circuit size. 2. Show a separate circuit for each water heater, E3702.11. 3. Use Table E3702.13 for sizing 15, 20 & 30 AMP branch circuit conductors and protection ratings. 4. Show or notate a disconnect means or a locking breaker for the water heater, E4101.5. If you have any questions please contact: Ken Van Karsen (520) 837-4912 City of Tucson Residential Plan Review |
