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. Previous comments not address - 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. The current plans to no reference a material nor show a connection to ROW sidewalk or Parking area proposed. Ensure dimension the path at the minimum 4-feet required.
2. As currently shown, there is no direct accessible route proposed from the front door of the new Dwelling to the driveway nor to the garage/parking area.

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
08/21/2026 Residential Zoning REQUIRES RESUBMIT PDSD TRANSMITTAL

PROJECT: TC-RES-0726-04163
2101 E Pinal Vista, Tucson AZ 85730
ADU (2nd Review)

TRANSMITTAL DATE: 08/21/2026

This site is located within the R-1 zone (UDC 4.7.8). A single-family residence is a permitted use in this zone (Table 4.8-2) subject to Use Specific Standards 4.9.7.B.5 - .9.

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. Because the ADU will be a new, separate unit, it will require its own address -e.g. “2101 E Pinal Vista Unit 2.” This address needs to be added to each page of the packet. Please contact Pima County Addressing at addressing@pima.gov or 520-724-9512 to verify and add the unit. After the address/unit has been added or verified you'll need to submit an address change request through the permit sub records to update this record.

Label each unit on the site plan.

2. The site plan provided is incomplete. Submit a Full site plan . All information other than building elevations should be shown on a single page. Here is the link leading to the “Full” site plan instructions: https://www.tucsonaz.gov/files/sharedassets/public/v/2/pdsd/documents/plan-samples/full-site-plan_feb2026.pdf Missing items include, but are not limited to the following:
a. Project Description – e.g. Garage Conversion to ADU – (#3 in the link above)

Please review this link to the landscape instructions and sample layouts: https://middle-housing-cotgis.hub.arcgis.com/pages/Residential-Landscaping-Code Please make sure to add the preferred watering method.

4. See Residential Engineering’s 8/05/2026 regarding ADA accessibility. Per the City of Tucson Inclusive Home Ordinance 10463: 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, sidewalk, or street to an accessible entrance. Ensure the route meets accessibility standards as articulated in Sections 402-404 of the Accessibility Standards. See also TSM 7-01.4.3 for specifications, including the minimum 4ft-width, slope and permissible composition materials. This is also #13 of the site plan instructions.

5. With the next submittal, please include the following items:
a. Proof of the new address for the ADU.
b. Revised site plan including all required information included above
c. Complete plan set per 8/17/26 Residential Building team comments – label each page.
