American Standard Home Additions & ADU: The Fort Lauderdale Owner’s Guide
Home additions and ADU construction in Fort Lauderdale for properties with existing American Standard fixtures and systems run $45,000 to $130,000 for a typical project, and we install them using the same American Standard lines you already trust. Most owners call us after they realize their growing family or rental plans have outgrown the original footprint, and they need a contractor who will integrate the new space with the American Standard plumbing, HVAC, and fixture setups already in place. You’ll get a written line-item price before we pick up a tool, and Luca Romano oversees every project personally.
Which American Standard Models This Applies To
American Standard doesn’t make “home addition” parts the way they make toilets and faucets, but the compatibility question is real: your existing American Standard plumbing rough-ins, venting, and fixture trim dictate how the new square footage ties in. Homes built in Fort Lauderdale from the mid-2000s onward commonly have American Standard Cadet or Champion series toilets, and those 12-inch rough-in measurements matter when we’re moving walls or adding a bathroom to an ADU. If your addition includes a bathroom or kitchenette, we match new American Standard fixtures to your existing ones so the supply lines, shutoffs, and trim kits don’t turn into a mismatched mess.
Here’s the compatibility gotcha most Fort Lauderdale owners don’t know: American Standard changed the flush valve sizing on some Champion models around 2018, so if your existing unit predates that, swapping in a brand-new Champion bowl during an addition can require a different tank-to-bowl gasket and fill valve. We carry both on the truck. This is where OEM matters on the rough-in components but quality aftermarket equivalents from Fluidmaster or Korky work fine for flappers and fill assemblies. Sawyer Remodel Fort Lauderdale is an independent contractor, not affiliated with American Standard, but we’ve worked with their product lines for years and know the quirks.

Signs Your American Standard Home Additions & ADU Is Failing
You might not think of a home addition as something that “fails,” but the American Standard components inside it absolutely can. Here’s what we see across Fort Lauderdale:
- Water pressure drops in the new bathroom while the original bathroom runs fine. This usually means the existing American Standard supply lines weren’t upsized when the addition was tied in. Fort Lauderdale’s older neighborhoods near Victoria Park and Rio Vista are notorious for undersized 1/2-inch trunk lines feeding too many fixtures.
- The ADU toilet runs constantly or rocks slightly after the slab settles. South Florida soil shifts, and a concrete addition can settle a quarter-inch in the first two years. A rocking American Standard bowl cracks the wax seal, which leads to slow leaks that stain the subfloor.
- Mold or musty smell in the new space within the first year. That’s often a venting problem, not a cleaning problem. If the addition’s American Standard fixtures weren’t vented to code, positive pressure pushes sewer gas back through the traps.
- Kitchenette sink drains slowly only when the dishwasher runs. The original American Standard drain line may share a branch with the new fixture, creating an airlock. This is a code-adjacent fix, not a snaking problem.
- Humidity in the ADU is consistently 10-15% higher than the main house. Florida is Florida, but a properly vented American Standard bathroom fan and correctly sized HVAC duct don’t leave condensation on the windows. If you’re wiping down glass every morning, the addition’s airflow was never balanced.

AfterReplacement Cost & What’s Included
In Fort Lauderdale, a home addition with American Standard plumbing and fixture integration runs $45,000 to $130,000. That’s the honest range. The spread comes from square footage, whether you’re adding a bedroom versus a full ADU with kitchenette and bathroom, and how much of the existing American Standard rough-in we can reuse versus replace. Here’s the breakdown:
- Home addition (bedroom, home office, or family room): $45,000 – $130,000
- ADU construction (full accessory dwelling unit with bath and kitchenette): $90,000 – $220,000
- Garage conversion to living space: $30,000 – $80,000
Every quote includes the permit fees, the American Standard fixtures and trim, the labor, the drywall, the paint, and the final inspection. The written price you approve is the price you pay. No change orders because we “discovered” something we should have caught during the walkthrough. If something unexpected does come up mid-project, we flag it before touching it and put the new number in writing. The 365-Day Done Right Promise covers the entire addition for a full year after we close out the punch list. If it’s not done right, we make it right.
DIY or Call Us?
You can check a few things yourself before picking up the phone. Walk the addition’s perimeter and look for hairline cracks in the slab or stucco. Run every American Standard fixture for five minutes and watch for pressure drops. Check under sinks for moisture after a heavy rain, because Fort Lauderdale’s afternoon downpours will expose any flashing or roof-to-wall tie-in mistakes quickly. That’s where a homeowner’s useful DIY inspection ends.
What you shouldn’t do is attempt to move a toilet rough-in, extend a vent stack, or cut into a load-bearing wall to “open up” the addition. Florida building code for additions and ADUs requires licensed work with pulled permits and passed inspections, including hurricane strapping and wind-load requirements that most homeowners never think about until the inspector fails them. Luca Romano grew up gutting houses in East Los Angeles and has handled some genuinely tight Fort Lauderdale builds near Las Olas Boulevard where the existing framing didn’t match any modern plan. The work either holds up or it doesn’t, we make sure it does. Call (754) 354-7423 and we’ll tell you if it’s a phone call fix or a needs-a-crew fix.
FAQs
A properly built addition in Fort Lauderdale should last 50 years or more on the structural side, with the American Standard fixtures inside typically giving you 15-25 years before trim or internal components wear out. The Florida factor is moisture and salt air, which shortens the lifespan of exposed hardware and unsealed wood if the flashing wasn’t right. Call (754) 354-7423 for an exact assessment, estimates are free.
Yes, and most jobs in Fort Lauderdale are partial repairs rather than full rebuilds. If the framing is sound but the American Standard plumbing rough-in or electrical tie-ins are failing, we fix those specific systems without tearing down the whole addition. The only time we recommend more extensive work is when water intrusion has compromised the structure, which is common in older garage conversions near the Intracoastal. Call (754) 354-7423 and we’ll tell you what you actually need, not what’s easiest for us to sell.
A single-room home addition typically takes 3-5 months from permit approval to final inspection, while a full ADU with bathroom and kitchenette runs 5-8 months. The Fort Lauderdale wildcard is the permitting office and hurricane season, both of which can add weeks you didn’t plan for. We build that into the schedule up front, and the written timeline is part of your contract. Call (754) 354-7423 for a project-specific timeline, estimates are free.
We keep common American Standard rough-in components, flush valves, fill assemblies, and trim kits on the truck, plus we order the specific series-matched fixtures for your project from our suppliers. We also work with KraftMaid for cabinetry, Cambria and Silestone for countertops, and a full roster of proven material partners so you’re not stuck with whatever the supply house had on clearance. Call (754) 354-7423 and we’ll confirm availability before you commit to a single dollar.
