Tips
- A straight like-for-like AC/heat pump/furnace repair or replacement (same location, equal-or-lesser capacity and weight, by a licensed contractor, up to 5 tons) is fully exempt from a mechanical permit under Article 7-1, § 7-1-6(B)(4)(h) — but replacing refrigeration systems inside a COMMERCIAL building always requires a permit regardless of size. Contractor
- A new residential heat pump/AC/mini-split installation (not a like-for-like repair) is billed at a flat $150 per the fee schedule and typically issued over-the-counter.
- Where plan review is required for larger or new-construction HVAC scope, the City's standard 3-4 week first-review / 1-2 week subsequent-review timeline applies.
