Mechanical Permits
Organize mechanical permit and calculation inputs.
Mechanical permits for HVAC equipment, ductwork, gas piping, and ventilation. Permit Junkie ties Manual J/D/S to your jurisdiction's IMC/UMC edition.
Overview
HVAC change-outs
We surface Manual J/D/S requirements, refrigerant-line-set length checks, and condensate routing for like-for-like and upsized swaps.
Gas piping
Available IFGC or UPC evidence can surface sizing-table, BTU-load, and shutoff-valve questions for qualified-professional review.
Ventilation
Kitchen-hood, bathroom-exhaust, dryer-vent, and test/balance document tasks can be organized when supported.
Frequently asked questions
- Do I always need a mechanical permit?
- Requirements depend on the authority, property, and scope. Permit Junkie can compare your project with available jurisdiction records, but unresolved or stale authority information is labeled for confirmation with the issuing department.
- How long does a mechanical permit take to approve?
- Approval time varies by authority, project complexity, review workload, and corrections. Permit Junkie shows a processing estimate only when a sourced record is available; confirm current timing with the issuing department.
- What documents do I need for a mechanical permit?
- Typical packets may include an application, scope of work, site plan, scaled drawings, and contractor information. Vizar builds a project checklist from your answers and available authority records, while visibly marking items that still need confirmation.
