/ Miami-Dade · Wall openings
A wall opening can change the allowed interior-side yard.
A louver, intake or exhaust penetration is an opening. The zero- and five-foot conditions in Miami-Dade Section 33-51 apply only to specified districts, interior-side yards and adjoining uses. Check the actual zoning, adjacent parcel and mixed-use status before placing the wall or outlet. This page is a field prompt, not a zoning determination.
Packet: wall openings PDF · ES. Survey: property line and highway right-of-way. County Section 33-51.
- For the specified business or industrial interior-side condition, an unpierced wall may qualify for zero feet and a wall with an opening may require five feet. This is not a generic permission for every district, rear yard, street yard or residential adjacency.
- Louvers, exhaust, make-up air, dryer vents, and operable sash are openings. Do not hide a louver in a “solid” wall on the permit set.
- 33-51(e): a dwelling over the shop is not “the commercial setbacks downstairs.” MEP lands inside the residential envelope.
- Where BU/IU abuts RU, EU, or GU, the side and rear numbers change. We do not replace that table. Rear twenty feet from a residential district boundary in the published text, alley width credited — confirm live.
- Spacing between buildings is Miami-Dade Fire Rescue (33-50(d), 33-51(f)). We do not invent Fire distances.

Zoning asking why the wall is pierced. Revision. The 180-day clock is a different door.
What to send
Which wall is on the property line, every penetration in that wall, and whether any floor is residential.
If the hood already punches the property-line wall
Send the wall. MasterBuild will say whether the exhaust still has no row — not whether Zoning will accept the opening.
