TL;DR
A grease trap in Florida runs a few hundred dollars for a small indoor unit and several thousand to well over $10,000 installed for an outdoor interceptor. No standalone grease trap license exists. A licensed plumber installs it under the Florida Building Code, and your city FOG program or onsite sewage rules set size and pumping. Confirm local permit timing. Nobody publishes a statewide price index.
How much does a grease trap cost in Florida?
A small indoor hydromechanical grease trap in Florida usually lands between $300 and $2,000 for the unit, plus a few hundred to about $1,500 to pipe it in if the rough-in is friendly. An outdoor gravity interceptor is a different animal. The tank alone commonly runs $2,000 to $8,000. Installed, plenty of Florida food shops see $5,000 to $18,000 once you add excavation, a traffic lid, and the high water table that shows up the minute you dig in South Florida.
Florida publishes no statewide grease trap price. Any page that hands you one number is guessing. The honest picture is a range, then a list of what actually moves it.
Water table is the sleeper cost. In much of Miami-Dade, Broward, and the Keys you hit water fast. Dewatering and bedding are real line items. A rural install on dry sand in the Panhandle is cheaper for that reason, not because the tank is different.
Your utility can also force the expensive option. If the FOG program says gravity interceptor, a $400 under-sink box is a waste of money. If you are on a septic system, state onsite rules set a 750 gallon floor for the grease interceptor. That number is in Florida Administrative Code 64E-6.013. [4]
Compare that with grease trap cost in Georgia if you also run a shop over the state line. The hardware looks similar. The paper does not.
Do not pre-buy a tank from the internet before the plumber and the reviewer agree on type and size. Returns on a 1,000 gallon concrete box are not a thing. Pay for a sizing sheet first. That one habit saves more cash than shopping brands.
What should you budget besides the tank?
The tank is not the bill. First-year cash is hardware, install, the building permit, sometimes a FOG discharge permit, the first pump-outs, and whatever the plumber or engineer charges to size and stamp the sheet.
Building and FOG fees are local. I will not invent a current county fee. Pull the fee schedule from your building department and the utility. Confirm it. Fees change.
A working budget looks like this.
| Line item | Typical market range | Notes |
|---|---|---|
| Indoor HGI unit | $300 to $2,000 | Rated in GPM, not gallons |
| Indoor plumbing labor | $250 to $1,500 | Rises if walls close |
| Outdoor interceptor tank | $2,000 to $8,000 | 750 to 1500 gallon class |
| Outdoor install and sitework | $3,000 to $15,000+ | Water table and lids |
| Design or sizing package | $200 to $1,500 | Worth paying for |
| Building or plumbing permit | Confirm locally | County fee schedule |
| FOG or wastewater permit | Confirm locally | Utility program |
| Single pump-out | $150 to $600+ | Size and access |
| First-year pumping | $600 to $2,400+ | Interval is local |
Those hardware and labor figures are market ranges from Florida bids and contractor quotes, not a state survey. Nobody has a good statewide data set. If a salesperson quotes far outside this without a site reason, ask why.
The numbers in the next section are the code thresholds that shove you from a $500 box to a $10,000 hole in the ground. Read them before you shop.
Do you need a license for a grease trap in Florida?
No. Florida does not issue a standalone grease trap license. What you need is the right contractor license to install it, the building permit, and whatever FOG or septic approval your site falls under.
Installation is plumbing. Florida Statute 489.113 says, "No person who is not certified or registered shall engage in the business of contracting in this state." [2] Plumbing contractor is defined in section 489.105. [3] Hiring an unlicensed installer to bury a 1,000 gallon interceptor is how you buy the job twice.
Pumping is a different paper path. Brown grease (what comes out of the trap) is not the same as yellow grease (fryer oil). Onsite systems have septage and food establishment sludge rules in 64E-6.010 and 64E-6.0101. [6] [14] Sewer-connected shops usually use a hauler the city has registered. Confirm the hauler list with your utility. Do not hand cash to a truck with no manifest.
Your restaurant still needs its public food service license under Chapter 509. [8] That is not a grease license. Inspectors will still ask how you handle FOG.
Ignore any website selling a Florida grease trap operator card. If a city runs a local FOG certificate for managers, it lives on that utility's program page, not a national upsell funnel. Confirm training rules with the utility that will inspect you.
How long does a grease trap take in Florida?
An indoor unit can go in during a single work day once the permit is in hand and the pipe run is open. An outdoor gravity interceptor takes longer on site. Digging, setting, connecting, and inspecting often spans several days. High water or traffic-rated lids add time.
The permit is the real clock. Florida building departments run their own queues. I will not invent a processing time. Some counties turn a simple plumbing permit in a few days. Plan review on a new interceptor with drawings can take longer. Confirm with the building department that will stamp the job. No approval guarantee exists here, on purpose.
Utility FOG review often sits on a separate desk from the building permit. Septic shops also wait on the onsite sewage reviewer. DEP now runs that program, still working from the 64E-6 rule set and section 381.0065. [7] Stack those clocks. Do not schedule the opening party on the plumber's first available Thursday.
If you are only swapping a like-for-like indoor unit, ask the building department whether the job is a simple permit or a full review. That one question saves weeks of wishful thinking.
Weather matters more than people admit. A week of summer rain in South Florida will sit a hole full of water. Budget slack if the interceptor is outside.
What size grease trap does Florida require?
It depends on sewer vs septic, and on the local FOG manual. There is no single statewide gallon number for shops on city sewer.
If the kitchen uses an onsite sewage treatment and disposal system, Florida Administrative Code 64E-6.013 sets a hard floor. "The minimum volume of a grease interceptor shall be 750 gallons." [4] The same rule also limits how large a single tank can be and pushes you to tanks in series when the calculated volume runs larger. Sizing methods live in 64E-6.008. [5] Have the designer run the math. Do not pick 750 because it is the minimum and hope the reviewer is sleepy.
On city sewer, the Florida Building Code, Plumbing, Chapter 10 requires an interceptor or grease removal device for grease-laden waste from food prep areas. [1] [9] Local utilities then layer FOG rules on top. Miami-Dade environmental rules and Orange County's FOG program are two examples of that second layer. [12] [13] Some cities want a gravity interceptor outside. Some accept a properly rated hydromechanical unit inside. Ask before you buy.
I have an opinion here. Oversize outdoor tanks on a tiny sandwich shop are a favorite way to light money on fire. Undersize indoor traps on a fried-food line are how you fail the first inspection. Pay for sizing. It costs less than a second excavation.
Menus change the calculation. A salad shop and a fried-chicken line are not the same fixture load. If you add a fryer six months later, call the reviewer before the equipment dealer. Retrofit outdoor tanks under a finished parking lot hurt.
Grease trap vs grease interceptor: what are you actually buying?
People say grease trap for everything. Reviewers do not. A hydromechanical grease interceptor (the indoor box, rated in gallons per minute) is not the same product as a gravity grease interceptor (the outdoor vault, rated in gallons).
The Florida Plumbing Code puts both families in Chapter 10. [1] Your utility's FOG language decides which family you must buy. If the manual says gravity grease interceptor and you hang a 20 GPM box under the three-compartment sink, you will redo it.
Hydromechanical units make sense on tight urban remodel jobs when the utility allows them and the menu is light. Gravity vaults make sense when the code official or the FOG coordinator wants detention time and access for a vacuum truck. Outdoor concrete in a high water table is miserable to set. Fiberglass can be easier. Both need the right lids if cars park on them.
If someone tries to sell you an enzyme drip instead of a trap, walk. Additives do not replace an interceptor the code already required.
Name the product correctly on the permit. Wrong words on the application create wrong inspections. That delay is free to the department and expensive to you.
How much does grease trap pumping cost in Florida?
A pump-out often lands around $150 to $600, sometimes more for a deep or blocked outdoor interceptor or a long hose run. Under-sink boxes usually sit on the low end. Big vaults cost more because the truck spends more time and the disposal ticket is heavier.
Florida has no official pumping price. Interval is what wrecks the annual number. Many city FOG programs start you on a 90 day schedule until you prove a different interval with logs. Confirm that with your utility. Do not take a 90 day comment as a statewide rule. It is a common local starting point, not a statute.
On septic, 64E-6.010 tells owners how onsite tanks and related devices get maintained. [6] Food establishment sludge has its own handling rule. [14] Keep the manifest. If the hauler cannot give you a ticket, they are not your hauler.
First year, budget several pump-outs plus one "the alley smells" emergency visit. If a sales pitch promises you will never pump because of a magic insert, that is a waste of money.
Yellow grease from fryers is a separate pickup, often at low cost or even a small credit when prices are decent. Do not mix yellow grease into the brown grease tank. You make both loads worse and you can lose the recycler.
Who can install a grease trap in Florida?
A certified or registered plumbing contractor, working under a local building permit. That is the default. Chapter 489 is the statute. [2] [3] The Florida Building Code is the install standard. [1] [9]
Homeowner self-install rules that work on a bathroom sink do not travel to a commercial interceptor. Food service is commercial work. I would not owner-build a restaurant interceptor. The inspection will not be friendly, and the utility can refuse the connection.
The hauler who pumps is not automatically allowed to install. The kitchen equipment dealer is not automatically a plumber. If the person quoting the tank cannot pull the permit in their name, stop.
Electrical grease removal devices need the electrical trade too. Keep the scopes clean so the inspection does not bounce for the wrong license on the card.
For a multi-state read, grease trap cost in Alabama and grease trap cost in California show how different the contractor paper looks once you leave Florida. Do not assume a crew that is legal in one state can pull a Florida plumbing permit.
How do Florida cities differ on FOG rules?
A lot. The state code is the floor. Cities and counties that run pretreatment programs write the FOG manual you will actually live with. Florida's pretreatment framework sits in Chapter 62-625 of the Administrative Code. [11] EPA's national pretreatment program is the federal backdrop those local manuals sit on. [10]
Miami-Dade runs a dense environmental code and a utility program that does not love surprises. [12] Orange County publishes its own FOG program for food service. [13] Jacksonville, Tampa, Pinellas, and smaller utilities each keep a version. Some want drawings. Some want a manager training sign-off. Some want quarterly pumping until you earn a longer interval.
That is why a used interceptor that passed in another county can fail here. I would call the FOG coordinator before I call the tank yard. Ten minutes on the phone beats a $12,000 wrong hole.
If you are comparing other states for a second unit, grease trap cost in Arizona and grease trap cost in Illinois are useful only as a reminder that local pretreatment, not a national myth, sets the real bill. Same lesson as a grease trap Florida project, different desk.
Do not copy a friend's Orlando setup into a Miami-Dade storefront. Friends are not the code.
Should you buy an indoor unit or an outdoor interceptor in Florida?
Buy what the reviewer will approve for your menu and your sewer or septic connection. That is the whole answer.
If you are on septic, you are almost certainly in outdoor gravity territory because of the 750 gallon minimum in 64E-6.013. [4] Indoor boxes do not meet that rule.
If you are on sewer, ask the utility in writing. Light menus in small footprints sometimes keep an indoor hydromechanical unit. Heavy fry volume, a hotel kitchen, or a campus cafeteria usually gets pushed outside.
My bias: if the utility allows indoor and your menu is sandwiches, salads, and a panini press, do not let a salesperson upsell a vault. If you run a breakfast fry line, do not try to hide from a vault with a tiny trap and a prayer. The camera inspection will find you.
South Florida outdoor installs cost more than North Florida outdoor installs, mostly dirt and water, not magic tanks. Indoor labor rates follow the same north-south pattern but the gap is smaller.
Access for the vacuum truck is part of the design. A legal tank you cannot pump is a fine waiting for a Friday night.
What paper do inspectors actually ask for?
They want proof the device exists, is the approved type and size, went in under a permit, and gets pumped by someone allowed to take the waste. That is the path. Not a national certificate on your wall.
Keep the approved drawing or cut sheet, the building permit and final, the FOG enrollment if your city runs one, and every pump manifest. On septic, keep the onsite permit package too. [7]
If you want a single stack of sizing worksheets and manifest pages, GreaseTrapPath has a $199 one-time Interceptor + Manifest Kit. We publish independently. We do not pull permits and we do not pump traps.
Inspectors vary. Some glance at the lid. Some ask for 12 months of tickets. Build the folder like the strict one is coming. It takes a cheap binder.
Digital photos of the empty interceptor after each pump help when a hauler's handwriting is garbage. I do that. It has settled arguments.
Put the utility's FOG contact sheet in the same binder. When a new manager starts, they should be able to find the pumping interval without calling you on vacation.
What happens if you skip the grease trap in Florida?
You fail the plumbing inspection, or you open and then catch a FOG enforcement action, or you kill a drainfield. Local pretreatment programs exist because grease in a sewer is a routine collection-system problem, which is why EPA's pretreatment guidance sits behind every city FOG manual. [10] [11]
On septic, grease in the drainfield is a system failure. Replacement drainfields in Florida are ugly money, often worse than doing the interceptor correctly the first time. [7]
Fines and cleanup bills are local. I will not invent a fine table. Read your utility's enforcement section. Some cities charge for the camera crew and the overflow response.
There is no clever exemption for "we only saute." If the code official says the fixture makes grease-laden waste, you are in Chapter 10. [1]
Opening without the final plumbing inspection is how people catch a stop-work and a failed food inspection in the same week. Sequence the trades. The trap is not a decoration you add after the first Friday rush.
What is a waste of money on a Florida grease trap?
Enzyme drips sold as a substitute for a required interceptor. Unlicensed install. Buying the tank before plan review. Skipping the traffic lid in a parking aisle. Mixing yellow grease into the interceptor to dodge a pickup. Online courses that pretend to be a state license.
Also a waste: the cheapest lid on a vault that delivery trucks will drive over. You will buy the lid twice, and maybe the tank.
Spend on sizing, on a licensed plumber who has passed inspection in that county before, and on a hauler who hands you a real manifest. That is the whole strategy.
If you want the worksheet bundle after you have the local rules in hand, start at /start. Read the utility PDF first either way.
Other state cost writeups worth a look if you run more than one shop: grease trap cost in Colorado and grease trap cost in Connecticut. Different desks, same habit of checking the local FOG sheet before you spend.
Frequently asked questions
Do you need a license for grease trap in Florida?
No standalone grease trap license exists. Install work needs a certified or registered plumbing contractor under Chapter 489 plus a local building permit. Pumping needs a hauler your utility or onsite program accepts. Your shop still needs its Chapter 509 food service license. Confirm every local FOG enrollment with the utility that will inspect you.
How much does grease trap cost in Florida?
Indoor units often run $300 to $2,000 plus install. Outdoor gravity interceptors commonly land $5,000 to $18,000 installed, sometimes more with dewatering. Pump-outs often run $150 to $600 each. Florida has no official price list. Confirm permit fees with the county and the utility. Site water table moves the outdoor number hard.
How long does grease trap take in Florida?
Indoor swaps can be one day after the permit is in hand. Outdoor vaults take several site days, longer if the hole fills with water. Permit and FOG review time is local. Confirm the queue with the building department and the utility. This page does not promise an approval date.
Is a 750 gallon interceptor required if I am on city sewer?
The 750 gallon minimum in rule 64E-6.013 applies to food operations on onsite sewage systems. City-sewer shops follow the Florida Plumbing Code and the local FOG manual instead. Some utilities still want a large outdoor vault. Ask the FOG coordinator in writing before you order a tank.
Can I install my own grease trap in Florida?
For a commercial kitchen, I would not. Contracting without the right certificate or registration violates Chapter 489. The building department and the utility can reject the work. Hire a plumber who can pull the permit in their name. Owner-builder habits from a house remodel do not carry over here.
How often do I have to pump a grease trap in Florida?
There is no single statewide interval for sewer-connected shops. Many utilities start you near 90 days until logs support a change. Onsite systems follow 64E-6 maintenance rules and the permit. Confirm the interval and the percent-full trigger with your utility or onsite reviewer. Keep every manifest.
Does a grease trap cost more in Miami-Dade than in North Florida?
Often yes for outdoor work, mostly because of water table, traffic, labor, and denser FOG review, not because the tank brand changes. Indoor box prices are closer statewide. Nobody publishes a clean county-by-county index. Get two local plumbing bids and read that county's FOG sheet before you compare rumors.
What is brown grease vs yellow grease in Florida?
Yellow grease is used fryer oil. Brown grease is what the trap or interceptor holds. Different trucks, different rules, different tickets. Do not pour fryer oil into the interceptor to save a pickup. Onsite sludge handling has its own rule in 64E-6.0101. Ask the hauler which waste stream they are permitted to take.
Do food trucks need a grease trap in Florida?
Many cities want the truck tied to a commissary that already has an approved interceptor, not a homemade box on the vehicle. That is a local FOG and food-license question. Confirm with the city that issues the truck permit and with the commissary's utility. Do not guess from a forum post.
Will a cheap under-sink trap pass in Orlando or Tampa?
Only if that utility's FOG rules accept a hydromechanical unit for your menu and fixture load. Plenty of Florida cities still want an outdoor gravity interceptor for heavy kitchens. A cheap box that fails review is a total loss. Get the written requirement first, then buy the device that matches it.
Are permit fees the same in every Florida county?
No. Building departments and utilities set their own fee schedules. I will not invent a current fee. Download the county building fee chart and the utility FOG application. Confirm both before you lock a budget. Fees change, and a second review can add cost.
What if my Florida building is on a septic tank?
Plan on a gravity grease interceptor that meets 64E-6, including the 750 gallon minimum, plus the onsite permit path under section 381.0065. Indoor GPM boxes will not satisfy that rule. DEP now runs the onsite program. Confirm current forms and the reviewer of record before you dig.
What records should I keep after the grease trap is in?
Keep the approved cut sheet or drawing, the building permit and final, FOG enrollment if required, and every pump manifest. Photos of the empty tank after service help. On septic, keep the onsite permit file too. A cheap binder beats arguing from memory when a new inspector shows up.
