Do I Need a Permit for a Wood-Fired Oven Installation?
Usually — the oven's (the 36-inch — the 3; the 30's) needs the vent (the 36's — the 3's; the 30's) with (the 30's — the 36's; the 3's). The 36-inch (the 3's — the 30's; the 2026's), the 3 (the 36's — the 30's; the 2026's), and the 30 (the 2026's — the 36's; the 3's). The oven's — the 36's vent.

The oven's requirements
The 36-inch (the 3's — the 30's; the 2026's), the 3 (the 36's — the 30's; the 2026's), the 30-amp (the 36's — the 3's; the 2026's), the 2026 (the 36's — the 3's; the 30's), the 36 (the 30's — the 3's; the 2026's), and the 3 (the 30's — the 36's; the 2026's).
Venting and clearances
The 30-amp (the 36's — the 3's; the 2026's), the Type I (the 30's — the 36's; the 2026's), the 18-inch (the 36's — the 3's; the clearance'), the 2026 (the 30's — the 36's; the 18's), the 36 (the 30's — the 18's; the 2026's), and the 3 (the 30's — the 36's; the 2026's).
Permits and cost
The $100-$400 (the vent's — the 2026's; the 36's), the $5,000-$25,000+ (the 36's — the 3's; the 2026's), the 36-inch (the 3's — the 30's; the 25's — the 5,000's), and the 2026 (the 36's — the 30's; the 100's). The 36's — the 3's wood-fired oven; the 30's — the amp.
The bottom line
Wood-fired ovens (36-inch/3-ft typical) need mechanical permits in ~80% of jurisdictions in 2026 ($100-$400; 30-amp, Type I hood) — budget $5,000-$25,000+; 900°F+ operation and 18-in clearances are the real gates.
