Do not cloud the changes made for comment updates; revisions are processed if changes occur after the permit is issued.

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 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 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. The ordinance revision now requires a gray drain line discharge from one fixture for a one story dwelling. Additional gray fixture drains are optional. Show a second clothes washer standpipe plumbed to an exterior wall above grade when feasible, or a bathing fixture drain looped 3’ beyond an exterior wall below grade before connection to the building drain. Use the appropriate detail at https://www.tucsonaz.gov/pdsd/water-energy-conservation
3. Show compliance with the Electric Vehicle Supply Equipment Ordinance adopted by the City of Tucson Ordinance #11844 on 6/22/2021. Include a 40 ampere 240 volt dedicated branch circuit with a NEMA 14-50R receptacle for charging an electric vehicle at a proposed parking space or show the distance from transit or a bike boulevard as not greater than a quarter-mile.

SITE PLAN:

1. Update the electric and water lines from meter to building, R106.1.1. Show all utility point of connections without dependance on another dwelling. TEP may require the service panel for the property at the closest building to the service transformer with an underground feeder from a dual meter to the more distant dwelling.
2. Show a street address for each dwelling on the site plan, R319.
3. Show the square footage of living space, garage and covered patios, R106.1.1.
4. Sewer lines passing through an easement require an agreement statement with a Pima County recorded document number, R106.1.1.

PLANS:

1. Show a maximum ½” floor elevation changes at a notated accessible route entrance on the floor plan, R106.1.1. Include the threshold condition at the vehicle doorway or an exterior hinged door when the garage is used for the accessible route.
2. Show the door from a garage to dwelling with a 20-minute fire rating (or 1-3/8” solid core) with self-closing and self-latching provision, R302.5.1.
3. Identify each wall line needed for enclosing a complete rectangle with sides no greater than 60’, Figure R602.10.1.1. Place these lines no further than 4’ from an actual parallel wall, so that corners are no further than 10’ from a “qualifying” braced wall panel.
4. Show interior braced wall panels with foundation anchor bolt connection to bottom plates, R602.10.8.3 and R403.1.6.
5. Show garage opening narrow panels with fastening details using a prescriptive method at Figure R602.10.6.2, R602.10.6.3 or R602.10.6.4.

SECTIONS - DETAILS:

1. Clarify the placement of ceiling/roof insulation for determining the need for attic ventilation or need for providing air-impermeable rigid insulation at the roof, R806. The section at A107 shows an attic space requiring venting, but the notation references an unvented application.
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, R806.5. Show a roof design with insulation types and minimum thickness for meeting the condensation control requirement and the minimum total insulation value of R-38.
3. Attic space requires a ventilation calculation for showing the attic vent opening size using 1 to 150 of attic area in compliance with R806.2. Provide appropriate upper and lower space vents when applying the reduced area calculation.

PLUMBING PLANS:

Show the system and appropriate flow rate setting on the plans. A four or five bedroom dwelling over 3000 SF requires a 90 CFM continuous setting.
2. Clarify the need for a gas piping diagram with the HVAC unit shown as a gas pack.

ELECTRICAL PLANS:

1. Show Bathroom receptacles with a separate 20 AMP dedicated circuit, E3703.4 and E3901.6. Update circuits at bathroom receptacles. Separate circuits at both bathroom receptacles and other locations.
