| 06/05/2026 | Residential Engineering | REQUIRES RESUBMIT | Permit Activity Number: TC-RES-0626-02933 (1st Review) Project: Additional Dwelling Unit/Guesthouse Location: 465 W MONTANA ST Review Date: 6/5/2026 Reviewer: Marco Contreras – Engineering Associate - Site Engineering Reviewer Contact: Marco.contreras@tucsonaz.gov Related cases: Plan review for the above referenced structure has been completed. This letter reflects comments to be addressed to ensure final approval from Site Engineering. To help speed up your resubmittal and facilitate shorter review timelines, please include a response letter along with your updated plans and any supporting calculations. In your response letter, address each comment individually and explain what changes were made and where they can be found in the plans. Please do not mark or highlight changes in the drawings at this stage — revision markups are only used after a permit has been issued. Submit your response letter and updated plan set as two separate files. Site Engineering Review Comments: 1. The City of Tucson Inclusive Home Design Ordinance requires all new dwellings — including ADUs, single-family residences, and duplexes — to provide an accessible route connecting the public street, sidewalk, or driveway to an accessible entrance of the home. This pathway must be shown, dimensioned, and labeled on the plans. What this means in plain terms: There needs to be a clearly defined, walkable path from where a person arrives (the street, sidewalk, or driveway) all the way to a usable door of the home — one that someone using a wheelchair or mobility aid could navigate without barriers. An exterior accessible route that shall conform to 2017 ICC A117.1 Sections 402 and 403 and City of Tucson Inclusive Home Design Ordinance. Reference: https://www.tucsonaz.gov/files/sharedassets/public/v/1/city-services/planning-development-services/documents/inclusivehomedesignordinance.pdf Action Items — Show the following on your plans: • Draw and label the path as "Accessible Route" • Provide a minimum clear width of 4 feet with a width call-out on the plans • Note the proposed running slope (must not exceed 5% / 1:20) and cross slope (must not exceed 2% / 1:50) • Identify the accessible entrance the route leads to Acceptable Accessible Route compositions include: • Portland cement concrete (PCC) • Broom Finished concrete • Brick or unit pavers (Only if set on a stable cement base with no gaps exceeding ½”) • Concrete pavers on concrete base (Same joint and evenness requirements as brick) • Flagstone: must be mortared – loose set does not qualify • Any surfaces equivalent in smoothness, hardness, and durability NOTICE: Decomposed granite (DG) is not permitted for required accessible routes, even if compacted |

| 06/12/2026 | Residential Zoning | REQUIRES RESUBMIT | PDSD TRANSMITTAL FROM: Roxanne Johnston Planner PROJECT: TC-RES-0626-02933 465 W Montana St., Tucson, AZ 85706 SFR (1st Review) TRANSMITTAL DATE: 06/12/2026 This site is located within the R-2 Zone (UDC 4.7.9). A single-family residence is a permitted use in this zone (Table 4.8-2) subject to Use Specific Standards 4.9.7.B.6, .9, & .10. RESUBMITTAL OF THE FOLLOWING IS REQUIRED: Correct plans, as noted in the comments below, along with a response letter indicating how all Site Zoning comments were addressed. 1. The proposed ADU exceeds the allowable square footage for such project. To be considered an ADU, it may contain only 75% of the principal structure’s square footage up to 1,000 sf. However, since the zoning is R-2, a second single-family residence is allowed for regular development. Change all ADU references to a Single Family Residence (SFR). Although the advantage to an ADU rather than an SFR is that an ADU does not require a parking space, both require landscaping (see Comment 2 ), a 4’-wide ADA pathway (see Comment 4), and are assessed impact fees. 2. Provide a landscape plan. As of January 1, 2026, via Ordinance No. 12219 (an amendment to the Unified Development Code), landscaping is required for all new single-family residential, middle housing development, and accessory dwelling units. A landscape plan is to be applied directly to the site plan and the instructions were designed to avoid hiring a landscape architect. Here is the instruction link: https://middle-housing-cotgis.hub.arcgis.com/pages/Residential-Landscaping-Code Essentially, one tree will be required in the front yard (per 1,000 sf of new development, which the SFR is), and then the front width of the lot minus the driveway multiplied by 5 to arrive at the ground cover requirements. Add which plants (plants are linked in the above link) will be used and the preferred method of watering to the site plan. Trees need to be planted 5 feet from the sidewalk and 10 feet away from any structure. Additional requirements are provided in the link. 3. Provide a parking space. If adding the space to the front yard, only 400 sf of parking is allowed. Parking is allowed to the rear and sides of the lot without a limit to size. If installing a parking space is not possible, the project can be relabeled as “Middle Housing” as the lot lies within a mapped area which makes the project eligible for a parking waiver because it several public transit stops and approved bicycle routes are within ¼ mile of the project. Here is the link to the parking waiver map: https://middle-housing-cotgis.hub.arcgis.com/pages/Parking-Waiver-Eligibility. If using the waiver option, please list the transit route lines and bicycle pathways shown by clicking on the yellow label on the property and using the tabs. 4. Per the City of Tucson Inclusive Home Design Ordinance (https://www.tucsonaz.gov/files/sharedassets/public/v/1/city-services/planning-development-services/documents/inclusivehomedesignordinance.pdf ), all new dwellings have a requirement to provide an “accessible route from public and common areas, including, but not limited to, a driveway or public street or sidewalk”. Draw, dimension, and label an accessible route from the driveway (or apron), sidewalk, or street to an accessible entrance. Ensure the route meets accessibility standards as articulated in Sections 402-404 of the ADA Accessibility Standards (https://www.access-board.gov/ada/chapter/ch04/). See TSM 7-01.4.3 for specifications, including slope and composition materials. This will be a 4’-wide pathway. 5. Show all structures and provide their dimensions on the site plan. Pima County Pictometry images shows an unpermitted shed along the east side of the house. If this shed is no longer there, please state so on the site plan. If it is to remain, please indicate whether it has utilities leading to it. 6. Additional comments may be forthcoming depending on responses to zoning review comments and plans submitted for the next review. If you have any questions about this transmittal, please contact Roxanne Johnston at roxanne.johnston@tucsonaz.gov . |
