/ Field knowledge · IMC 304.10
Flush with the dirt is not 304.10.
The slab under the condenser is three inches above adjacent grade. Or the unit is suspended six inches. Flush with the dirt is not 304.10. Original Masterbuild writing from Daily Code Talk. Confirm the adopted edition. This is not a pad design and not a soil report.
Packet: 304.10 PDF · ES. Source: IMC 304 Part 3. Guards: 304.11. Setback: ten-foot survey. Change-out: serials on the form.
- Call the elevation. “On a pad” is not an elevation. Annotate +3 in above adjacent grade, or +6 in if suspended.
- A change-out poured on the old footprint at grade is how you fail the first mechanical inspection after the truck leaves.
- 304.10 is support and elevation. 306.5 is how you get to it. Condensate still has to terminate. We do not invent Article 110 numbers here.
- A legal 304.10 pad can still sit inside ten feet of the property line. That is the survey packet.
- House Bill 803 did not exempt mechanical. A residential change-out still needs a mechanical permit in Miami-Dade.
New condenser on a pad poured flush with the lawn, condensate dumped at the slab
Inspector with a tape. Rework the pad or fail.
What to send
Photo of the existing pad or the proposed elevation, and whether this is a change-out or new equipment.
If the pad is already flush with the dirt
Send the photo. Masterbuild will say whether 304.10 still has no +3 in row — not whether the inspector will pass the old footprint.
