Do I need an HVAC permit in Orlando? The mechanical permit, the $15,000 notice rule, fees and inspections

The Orlando rule

The City's mechanical permit application (updated 12/24, read 23 October 2026) covers "Addition", "Alteration", "New" and "Repair/Replace", and asks for tons, heating kW, system type (split, package, mini split), whether the space was previously air conditioned, and the SEER2 or HSPF rating. So a like-for-like change-out is permit work, not maintenance.

The July 2026 state exemption for small jobs does not change this. The City's HB803 exemption guide lists "Electrical, plumbing, mechanical, or gas work" as "not eligible for exemption, regardless of cost".

The roof-equipment rule is from the City's mechanical plan review checklist.

Who pulls it

Usually a Florida-licensed air-conditioning or mechanical contractor: DBPR lists both among the categories that "require registration or certification" (DBPR FAQ). The City form notes that "Current license and insurance information must be registered with Permitting Services or provided with this application." 91.2% of the 759 HVAC firms on Orlando permits matched an active DBPR license in our file.

A homeowner can apply as owner-builder. Section 489.103(7) exempts owners "acting as their own contractor and providing direct, onsite supervision themselves of all work not performed by licensed contractors" on a one- or two-family home for their own use. The mechanical form needs a notarized owner signature when the work is not part of a building permit.

How to apply and what gets inspected

1. Fill in the mechanical application and email it to digitalpermits@orlando.gov for digital review, as the form instructs.
2. Record a Notice of Commencement only if your job is not an under-$15,000 replacement and is over $5,000.
3. Pay in the City's Permit Lookup tool.
4. Inspections. The City's inspection codes for mechanical work are 135 above ceiling, 200 rough-in, 375 refrigeration, 378 performance test and balance, and 600 final. Which of them your job needs is set when the permit is issued; ask the contractor for the list.

For an existing single-family home under $15,000, the City says it responds within 5 business days of a complete application (Building Permit Guidelines).

What it costs

From the 2026 residential fee schedule:

Worked out from the schedule: an $8,000 change-out is $66.24 + 7 × $11.03 = $143.45, about $148 with the surcharge; a $12,000 heat pump is $187.57 before it. The City says it is reviewing fees after HB803, so check the invoice.

What 8,269 Orlando HVAC permits show

The usual filed value, $8,484, sits well under the $15,000 line, so most Orlando change-outs need no Notice of Commencement. The slow part is the final: 91 days is more than three times a roof permit's 27, which usually means the final was booked late, not that the install took months. Ask who books it before you pay the balance. Prices by job size: Orlando HVAC cost page.

What this does not tell you

Our Orlando HVAC trade also includes gas permits. A permit records the declared value and dates, not the unit's brand or whether it was sized correctly. Almost every Orlando permit is eventually closed, so we show speed to final instead of a finished share. City of Orlando addresses only.
