Doorbell & Video Doorbell repair in Orlando, FL

Updated 2026-08-06 · Sources verified 2026-07-20

Thinking about a doorbell or video doorbell install in the Orlando area? Here's what actually matters — permit rules for Orange County and the City of Orlando, plus the mistakes and code requirements that trip up homeowners, sourced from manufacturer manuals and the Florida Building Code.

Do you need a permit?

It depends on the exact scope. Orange County and the City of Orlando require permits for more than most homeowners expect — and the rules change. Check the county's official "Do I Need a Permit?" page or call your local building department before starting work.

Orange County and the City of Orlando run separate permit offices with separate portals — and your mailing address alone doesn't tell you which one covers your home. Check which permit office covers your address →

Key facts before you start

A video doorbell needs two numbers from its transformer, not one. Ring and Nest both specify 16-24 VAC AND 10-40 VA, and VA is the one people miss. Ring's hardwiring spec for its Pro line reads "Hardwired transformer (16 to 24 VAC, 50/60Hz, 10VA to 40VA)"; Google's is "You need a transformer that is rated for 16-24 V AC, 10-40 VA to provide enough power to your doorbell." Homeowners read the 16V stamp on the old transformer, see a match, and buy the device — then it browns out, because the old chime transformer was sized for a solenoid that draws current for one second, not a camera that runs continuously. Ring's battery models accept a wider 8-24 VAC / 5-40 VA range on the same page, so "my neighbour's Ring worked on this transformer" proves nothing about a Pro.
Undersizing does not just underperform — the manufacturer says it can damage hardware. Ring: "Using the wrong power rating for your transformer, in-home chime, or Ring doorbell can: Damage your devices. Stop your in-home chime from working properly." Google's field symptom for the same condition is a doorbell "blinking a yellow light on the front," which means it is not receiving enough power. If you see that, stop and fix the supply rather than working around it.
The wire is a spec too. Ring: "Use 16- to 20-gauge wire for your Ring doorbell. Wires that are too thin or too thick might not deliver enough power to your Ring device." Too thin starves it, and too thick will not seat properly in the terminals. On a long run from the transformer, gauge and distance interact — a device that browns out at the door with a correctly rated transformer is worth checking here before the transformer gets replaced a second time.
The in-home chime is the other half, and the required part is usually in the box. Google states the wired Nest Doorbell "must be installed with the chime connector included in the box" when wired to an existing chime, because the connector lets the chime's wires deliver constant power and protects the chime from damage. Ring's equivalent is mandatory too: "You must use the Pro Power Kit with your Wired Doorbell Plus and Pro to make sure that they receive the right amount of power to work correctly" — and the app's Chime Type setting has to be changed to match what you actually have. A buzzing chime after a video-doorbell install is far more often a missing or miswired connector than a bad chime.
For a plain wired doorbell that stopped working, the transformer is one of three suspects and the cheapest two are outside. Broan-NuTone's chime instructions send you to "check the pushbutton(s) for poor contact or loose connections and wiring for short circuits" — the exterior button lives in weather and is the usual failure. If the chime plungers are sluggish, Broan says clean them with a nonflammable cleaning fluid and wipe dry, and warns in capitals: "NEVER OIL CHIME PLUNGERS." Oil collects dust and seizes them permanently. For sizing a plain chime, Broan's factory guide specs a 16 volt, 10 VA transformer for a single door chime, stepping up to 20 or 30 VA for two or more.
Do not assume "it is only low voltage, so no permit." That exemption is a local decision and Orange County has not published one. The county's Division of Building Safety states that "A low-voltage permit is required for security systems, burglar alarms, cable TV, closed circuit TV, data cabling, phones and speaker wires unless exempted by statutory requirements," and its electrical permit page uses "garage door openers, doorbells, chimes" as its own examples of low-voltage work. There is no statewide hook to point at either: the Florida Building Code's Section 105.2 "Work exempt from permit" list contains only Gas, Mechanical and Plumbing categories, so the model-code exemption for equipment operating under 25 volts is not in Florida's version. Miami-Dade publishes an explicit residential low-voltage exemption; Orange County does not. Ask before you assume.
If the transformer does need replacing, that part is line-voltage work. The transformer is fed by a 120V branch circuit — usually mounted at the panel, in the garage, or above a ceiling access panel — so replacing it is not the same job as swapping the button. In Florida a homeowner may do their own electrical work under FS 489.503(6)(a), which covers "an owner of property making application for permit, supervising, and doing the work ... for his or her own use and occupancy and not intended for sale." Read that as written: it assumes the permit. See the light switch guide for how that exemption works and why the new \$7,500 permit waiver does not cover electrical.
