West Jordan room addition permit rules — SDC D2 engineering
Room additions in West Jordan require building and trade permits through the Cityworks portal at permit.westjordan.utah.gov or in-person at 8000 South Redwood Road. Phone: (801) 569-5050. Engineer-stamped structural plans are required for all addition structural work — framing, connections, hold-downs, shear walls, and foundation must be designed for SDC D2 seismic loads. A structural engineer with experience in Wasatch Front seismic design is essential for West Jordan room additions.
Call 811 at least 3 business days before foundation excavation. Rocky Mountain Power, Enbridge, and city water/sewer lines must be located. The footing inspection before concrete pour verifies that footings extend below the 30-inch frost depth.
The residential energy code for West Jordan room additions is the 2015 IECC (not the more recent 2021 IECC) for Climate Zone 5B. This older energy code is less demanding than the 2021 IECC used in many other states. Climate Zone 5B specifications under the 2015 IECC: ceiling R-49, walls R-13+R-5 continuous, windows U-0.32 maximum, SHGC 0.40 maximum.
| Variable | How it affects your West Jordan addition permit |
|---|---|
| SDC D2: engineer-stamped plans required | Most critical requirement. All structural elements must be engineered for SDC D2. Hold-downs, shear walls, roof-to-wall connections, foundation connections. Engineering fee: $2,000–$4,500. Structural engineer with Wasatch Front seismic experience required. |
| 30-inch frost depth | Addition footings must extend 30 inches below grade. Footing inspection before concrete pour. Call 811 at least 3 business days before excavation. |
| 2015 IECC energy code (Zone 5B) | West Jordan uses 2015 IECC (not 2021). Climate Zone 5B: ceiling R-49, walls R-13+R-5, windows U-0.32 max / SHGC 0.40 max. Less demanding than 2021 IECC requirements in some other states. |
| Rocky Mountain Power & Enbridge | Call 811 to locate both utilities before foundation excavation. Coordinate with Rocky Mountain Power and Enbridge for new HVAC and electrical connections in the addition. |

Common questions about West Jordan UT room addition permits
How do I apply for a room addition permit in West Jordan?
Cityworks portal at permit.westjordan.utah.gov or in-person at 8000 South Redwood Road. Phone (801) 569-5050. Engineer-stamped SDC D2 structural plans required. Call 811 before foundation excavation.
Why does West Jordan require SDC D2 engineering for additions?
West Jordan's official design criteria designate residential construction at Seismic Design Category D2 — the same seismic classification as coastal California — due to the Wasatch Fault. Every structural element of the addition must be designed by a structural engineer for SDC D2 seismic loads: hold-downs, shear walls, roof-to-wall connections, and foundation connections. This is more demanding than all other inland US cities in this guide.
What energy code governs West Jordan room additions?
West Jordan uses the 2015 IECC (not the more recent 2021 IECC) for residential energy provisions. For Climate Zone 5B: ceiling R-49, walls R-13+R-5 continuous insulation, windows U-0.32 maximum and SHGC 0.40 maximum. The insulation inspection before drywall verifies compliance.
How deep do addition footings need to be in West Jordan?
West Jordan's frost depth is 30 inches. All addition footings must extend 30 inches below grade. The footing inspection before concrete pour is the critical checkpoint. Call 811 (Utah underground utilities) at least 3 business days before any foundation excavation.
How much does SDC D2 structural engineering add to an addition cost?
Structural engineering for a West Jordan room addition: approximately $2,000–$4,500 for engineer-stamped plans covering SDC D2 framing, hold-downs, shear walls, and connections. This fee is higher than in non-seismic or lower-seismic markets but is a necessary investment for a safe and permitted addition on the Wasatch Front.
