Project-specific application handoff
This separates confirmed filing facts from official starting routes and missing details. A mapped link is not presented as a verified fee, attachment list or parcel determination.
Still requires confirmation: fee calculation, final closeout steps, parcel jurisdiction.

A practical permit path
Some Austin-area properties are outside full-purpose city limits or inside another jurisdiction. Verify the parcel and any extraterritorial rules first.
Document the equipment, location, connections and any related structural, electrical, plumbing, fuel or fire work.
Ask Austin Development Services which permit type applies and whether the homeowner or a locally qualified contractor must apply.
Expect at least a mechanical final when the work is permitted. Electrical, gas or energy inspections may be added when those systems change.
Conditions that change the answer
Like-for-like equipment
Matching the existing type, capacity and location may keep the project on the simplest available permit path.
Relocation or new ductwork
Moving equipment or changing distribution can add drawings, access, clearance and energy-code questions.
Gas or electrical changes
A new disconnect, circuit, gas line or vent can add a separate trade scope and inspection.
Inspection and close-out
Expect at least a mechanical final when the work is permitted. Electrical, gas or energy inspections may be added when those systems change. Keep the approved documents, inspection results and final permit record with the property files.
