The full field is 631 firms. The 25 listed here account for 31.6% of every mechanical permit issued; the rest is a long tail, and 334 of the 631 firms filed exactly once in the period.
How concentrated the mechanical market is
Bars are scaled to the busiest firm. The percentage is that firm's share of every mechanical permit issued in the period.
This is a fragmented market. Ten firms out of 631 hold only 23.3% of the permits, so a strategy built on the top of the table reaches a small minority of the work. The busiest single firm holds 9.3% on its own, and 53% of the 631 firms in the record filed exactly one permit in the period, which is the usual shape of a permit long tail: a small number of production contractors, and a large number of firms doing occasional or single-property work.
What a permit count measures, and what it does not
A permit count is a measure of filing frequency. It is the closest public proxy for how much work a trade contractor is currently taking on, and it has the useful property of being impossible to inflate: a permit costs money and creates an inspection obligation, so nobody files one for marketing reasons.
| A high permit count tells you | It does not tell you |
|---|---|
| The firm is actively working and has capacity in use right now | How large the jobs are, unless a stated value is published with them |
| It is licensed and in good standing, because an unlicensed firm cannot pull the permit | Whether the work was done well, or on time |
| It works in this jurisdiction, which a company website often overstates | How much of its revenue comes from this jurisdiction |
| It is large enough to run permitted work continuously | Headcount, revenue, or whether it is hiring |
| Its work is recent, which the last-filed date shows per firm | What it is bidding next, which no public record contains |
One more limit worth stating plainly: a firm that subcontracts under someone else's license does not appear here at all, and a firm that pulls permits on behalf of others appears larger than it is. The record names whoever signed, which is not always whoever did the work.
How to use this list
If you sell to mechanical and HVAC contractors
This is a prospect list ordered by demonstrated buying capacity. A mechanical contractor filing 160 permits in six months is consuming materials, equipment, labor and subcontracted services continuously, and the permit record proves it in a way a company website cannot. Start at the top, and use the last-filed date to skip anyone who has gone quiet.
If you are a general contractor or developer looking for capacity
Volume is a capacity signal, not a quality one, so treat the ranking as a shortlist to check rather than a recommendation. The firms near the top are demonstrably able to run several permitted jobs at once. Verify license standing and references separately; this page reports what was filed, not how it went.
If you are a mechanical contractor yourself
This is your competitive set, measured rather than guessed. The share-of-market column tells you what a realistic position looks like in Miami-Dade County: the busiest firm holds 9.3% of all mechanical permits, which means even the leader competes for most of the work.
How this ranking was built
Every step is reproducible from the public record. Nothing is weighted, scored or editorially ordered.
The counting is deliberately plain. There is no weighting by job size, no adjustment for permit type, and no editorial ordering. Two firms with the same number of permits are ranked alphabetically, and the only judgment applied anywhere is deciding when two differently punctuated names are the same company.
That last judgment is where the errors would live, so it is made conservatively. Punctuation and spacing are normalized, which merges ARNOLD J. ELECTRIC INC with ARNOLD J ELECTRIC INC. Legal suffixes are not touched, so a firm filing as an Inc and an LLC stays as two entries: they can genuinely be two companies, and merging them would be a worse mistake than leaving them apart.
Where the names in this table come from
Miami-Dade names the licensed qualifier on each trade permit and states a construction value on the large majority of them, which is why this is the one of the three cities where a dollar column is honest. Three notes on reading it.
- The stated values pass the same screen the county reports use: a single permit at or above $1B is dropped, and a value of $10M or more repeating across five or more permits in the same city is dropped as a parent project total stamped onto its own sub-permits. Without that screen Miami-Dade's raw half-year total is $103.7B, most of it a folio number sitting in the cost column of a pool permit.
- A firm's dollar figure is the sum of the values on its own permits, so a specialist doing many small jobs ranks high on count and low on value, and a firm on two towers does the reverse. Neither is a quality signal.
- Swimming pool contractors appear in the plumbing ranking. That is correct rather than a misclassification: in Miami-Dade a pool is permitted as plumbing work. If pools are not your market, read past them.
Permits are a record of work already awarded
Everything above describes work that has already been won. A permit is issued after the contract is signed, which makes this page an excellent map of who is active and a poor list of what to bid on. The buying decision for most trades lands around a third of the way through a build, at framing, well before the trade permit is filed.
That is the distinction Builtie is built around: watch the project record from the planning and permit stage forward, identify the developer or general contractor behind it, and reach the person who decides your scope while the package is still open. When to contact each trade sets out the timing by discipline, and construction leads in Miami-Dade covers what the platform tracks in this market.
Builtie plans start at $550 per month per seat for 50 matched projects a month, and $880 for 200. Every plan includes done-for-you LinkedIn and email outreach, and there is a 7-day free trial with 10 projects.

Frequently asked questions
Who is the most active mechanical contractor in Miami-Dade County?
KARIBE MECHANICAL SERVICE LLC, with 160 mechanical permits issued in the first half of 2026. That is 9.3% of all 1,724 mechanical permits in the period. OSCAR AIR CONDITIONING INC and MPP GROUP CORP are next, with 116 and 30.
How many mechanical and HVAC contractors are there in Miami-Dade County?
631 distinct firms were issued at least one mechanical permit in the period. That is the number actively pulling permits, not the number holding a license, which is larger: a licensed firm that worked only as a subcontractor under someone else's permit does not appear.
Where does this ranking come from?
Every mechanical permit issued by Miami-Dade County in the period, taken from the public record. Firms are counted by the number of permits naming them, with punctuation and clerical markers normalized so one company is not split across several spellings. No weighting, scoring or editorial ordering is applied.
Does a high permit count mean a contractor is good?
No. It means the firm is licensed, active, and running enough permitted work to file frequently. It says nothing about workmanship, schedule or price. Treat the ranking as a shortlist of firms worth checking, and check them.
Can I use this to find mechanical and HVAC contractors to sell to?
Yes, and it is the most direct use of the page. A firm at the top of this table is buying materials, equipment and subcontracted services continuously, and the permit record proves activity in a way a website cannot. The last-filed date on each row tells you who is still moving.
What is the stated value column?
The construction value declared on that firm's own permits, added up. It passes a screen that drops any single permit at or above $1B and any value of $10M or more repeated across five or more permits, both of which are data-entry artefacts rather than real projects. A firm doing many small jobs ranks high on count and low on value; that is a difference in work type, not in size.
How do I find projects before the trade permit is filed?
A trade permit is issued after the contract is awarded, so this page maps who is active rather than what is open to bid. Builtie tracks projects from the planning and permit stage and names the developer, general contractor and specifying designer behind each one. Plans start at $550 per month per seat for 50 projects a month and $880 for 200, with a 7-day free trial that includes 10 projects.
