| 03/17/2026 | Residential Building | REQUIRES RESUBMIT | TC-RES-0126-00347 2nd PLAN REVIEW COMMENTS Plan review for the above referenced structure has been completed. This letter reflects comments to be addressed. For facilitating a shorter back check time, please provide 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 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 2024 International Residential 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 REQUIREMENTS: The City of Tucson adopted the 2024 IRC with amendments and building ordinances for all dwellings. A permit requires the correct application type. Request the cancellation of this application for an ADU and apply for a new dwelling permit. A primary dwelling permit requires features that are not necessary for an ADU. Provide a separate response letter addressing each comment with location of change on the plans. ELECTRICAL PLANS: 1. Specify the Electric Vehicle NEMA 14-50R receptacle at a parking area, N1104.2.1. 2. Label a double breaker space for future Photo Voltaic on the panel schedule opposite end from the main/supply side, T103.9. If you have any questions, please contact: Kenneth.VanKarsen@tucsonaz.gov City of Tucson Residential Building Safety |

| 03/26/2026 | Residential Zoning | REQUIRES RESUBMIT | 1. COMMENT: One tree per 1,000 sf of floor area is required. The total proposed square footage is 1,638 sf, which requires two trees. 50% of required trees must be in the front yard setback area. Show an additional tree within the front yard setback area. 2. COMMENT: The required vegetative groundcover must be located on the site/lot, and not in the public right-of-way (ROW). The site plan shows the vegetative groundcover to be within the ROW, which is not permitted. 3. COMMENT: In a note, indicate method of watering for the required landscaping. 3. COMMENT: The full text of the Middle Housing landscape requirements is provided below. Ensure the landscaping shown on the plans is compliant with the following: UDC 7.6.8. NEW SINGLE FAMILY, MIDDLE HOUSING, AND ACCESSORY DWELLING UNITS A. The following landscaping is required for all new single family residential, middle housing development, and accessory dwelling units. These requirements do not apply to new single family residential dwellings within subdivisions of 5 or more units. 1. One canopy tree is required for every 1,000 square feet of gross floor area of the development project. 2. Vegetative groundcover is required within the front yard setback per the calculation below. (X Linear feet of Street Frontage) – (Y Curb cut width) x (5 Foot Depth) = Z Square Feet of vegetative groundcover An example, using a parcel with 115 feet of street frontage and a 15-foot curb cut: (115 Linear Feet of Frontage) – (15 curb cut) X (5 Foot Width) = 500 Square Feet of vegetative groundcover required within the front yard setback. Parcels with less than 30 linear feet of street frontage may place the required groundcover in alternate locations indicated on the site plan. Irregular-shaped lots, including flag lots, will use the street frontage parallel to their parcel (see Figure 7.6.2.A). 3. Plants must be low to very low water use with a hardiness rating of 15 degrees Fahrenheit or lower and non-invasive. Options are listed in Section 5-02.5.0 of the Technical Standards Manual. Exceptions to these criteria or plants that are not listed in Section 5-02.5.0 of the Technical Standards Manual, may be approved by the PDSD Landscape Architect. B. Required landscaping must be located as follows: 1. A minimum of fifty percent of the required canopy trees must be located within the front yard setback area. a. Exception: If site constraints prevent new tree placement in a front yard, five shrubs may be substituted per required tree. Required trees must still be placed elsewhere on the site. Shrubs used as a substitute plant material for the required tree shall range from three feet in height by three feet in width, or larger. Shrubs must follow the relevant spacings from utility lines in section 5-01.5.11of the Technical Standards Manual, but can be planted one radius of their mature width from foundations, enclosed sidewalks, sidewalks, and curbs. b. Exception: The tree required for an accessory dwelling unit may be placed anywhere on site. 2. Trees may be planted at varying distances apart. 3. Required landscaping is not restricted to the first 10 feet onto the property from the existing or future right-of-way line. 4. Newly planted trees must be placed at a minimum distance from existing or proposed City of Tucson-owned or private utility-owned lines, as found in section 5-01.5.11 of the Technical Standards Manual. Tree plantings are not permitted in El Paso Gas Easements or under overhead power lines. 5. Trees shall be placed a minimum of ten feet from the center of the tree trunk to any enclosed structure. 6. Trees shall be placed a minimum of five feet from the back of the sidewalk or curb. If this standard cannot be met, then root barriers are required and must be illustrated on the submitted construction plans. 7. Trees must be planted in a six-to-nine-inch depressed planting area of at least 50 square feet (four-foot radius, or alternatives as proposed) and at least ten feet away from a building foundation. 8. Existing, established trees on property, at least 4 inches trunk diameter at chest height, located at least ten feet from the foundation or with an unobstructed dripline at maturity, shall count toward this requirement (Figure 7.6.2.B). The root systems of existing trees used for this requirement must be protected from soil compaction during construction using perimeter protective fencing around the dripline. Established trees are not required to have a depressed planting area. Existing shrubs and vegetative groundcover may also be used toward the required landscaping. Figure 7.6.2-B: Obstructed and unobstructed driplines on various size trees, located 10 feet from an existing structure C. Vegetation shall be established, maintained, and sustained throughout its life in support of the City’s tree count, climate, and walkability goals. One of the following two options may be used: 1. Drip or bubbler irrigation with backflow protection. A simple irrigation system can be part of the domestic water supply for the residence. 2. Alternate methods, such as rainwater harvesting, hand watering, and greywater systems, as proposed by the property owner and approved by the PDSD Landscape Architect. D. Proposed landscaping and related items can be included in a residential plot plan; a Landscape Plan is not required.
