AfterHow Much Does Home Addition Cost in Fort Lauderdale?
A home addition in Fort Lauderdale typically costs between $45,000 and $130,000 in 2026. Most homeowners adding a bedroom, bathroom, or expanded living space can expect to pay $180 to $350 per square foot, depending on finishes, foundation work, and whether the addition goes up or out. At Mason Remodeling Co Fort Lauderdale, we put a written price in front of you before any work starts, so you never have to guess where the final number will land.
Here’s the direct answer: a 400-square-foot bedroom suite addition in a neighborhood like Victoria Park or Coral Ridge generally runs $85,000 to $115,000 when it includes a bathroom and closet. A simpler bump-out for a larger kitchen or family room might start closer to $50,000. The range is wide because Fort Lauderdale’s permitting requirements, flood-zone elevation rules, and soil conditions all pull the number in different directions. We’ll walk through exactly why in this guide, with real dollar figures so you can self-qualify before you call.
Key Takeaways
- Full home additions in Fort Lauderdale: $45,000 – $130,000, with most projects landing between $85,000 and $115,000
- Cost per square foot: $180 – $350, driven by finish level, foundation type, and design complexity
- FEMA flood-zone requirements and elevation certificates can add $5,000 – $20,000 to a project
- Expect 4 – 8 months from permit approval to final inspection for a typical addition
- Mason Remodeling delivers a written price before work begins, on every project, every time
Home Addition Cost Breakdown (2026)
Here’s how the numbers actually break down for Fort Lauderdale home addition projects. These figures come from our own project history and current 2026 market conditions in Broward County:
| Cost Component | Typical Range |
|---|---|
| Design & architectural plans | $4,000 – $12,000 |
| Engineering & structural drawings | $2,500 – $7,000 |
| Permits & impact fees (City of Fort Lauderdale) | $1,500 – $6,000 |
| Foundation & slab work | $8,000 – $25,000 |
| Framing (walls, roof, structural) | $12,000 – $35,000 |
| Roofing (tie-in or new section) | $4,000 – $14,000 |
| HVAC extension or new system | $3,500 – $12,000 |
| Electrical work | $3,000 – $10,000 |
| Plumbing (if adding bath/kitchen) | $3,500 – $12,000 |
| Drywall, insulation, paint | $4,000 – $12,000 |
| Flooring | $2,500 – $9,000 |
| Windows & doors (impact-rated) | $3,000 – $12,000 |
| Finishes (trim, hardware, fixtures) | $2,500 – $10,000 |
Those line items explain the spread. A no-frills 300-square-foot addition with basic finishes in a neighborhood like Melrose Park can come in around $50,000. The same footprint with a bathroom, impact windows, and custom millwork in Rio Vista can push past $110,000. The single biggest swing factor is whether you’re adding a bathroom or kitchen to the new space, because plumbing and ventilation costs hit hard and fast.
One thing specific to Fort Lauderdale: many homes in neighborhoods like Shady Banks, Riverside Park, and Sailboat Bend sit in flood zones that require elevation certificates and potentially raised foundations. That’s not a “maybe” cost. It’s a line item, and it ranges from $5,000 to $20,000 depending on your property’s base flood elevation and the addition’s finished floor height.
What Affects Home Addition Pricing in Fort Lauderdale
Fort Lauderdale pricing doesn’t work like it does in Dallas or Phoenix. Here are the local factors that genuinely move the number:
- Flood zone designation. If your property falls in an AE flood zone, which covers significant portions of Fort Lauderdale east of US-1 including parts of Las Olas Isles and Harbor Beach, your addition may need to be elevated or designed with flood vents. That adds structural cost and often requires an engineer’s floodplain analysis. Expect $5,000 – $20,000 in additional design, materials, and engineering.
- Wind-load and impact requirements. Broward County sits in a High Velocity Hurricane Zone. Any new windows, doors, or roof sections must meet Miami-Dade or Florida Building Code impact standards. Impact-rated windows cost 30 – 50% more than standard windows. On a full addition, that’s a real number, not a rounding error.
- Foundation type. Fort Lauderdale’s high water table means many additions need a monolithic slab with deeper footers or, in some areas, helical piles. If your existing home is on a raised foundation, matching it can add $10,000 – $30,000 depending on the structure and soil conditions.
- Second-story vs. ground-level addition. Going up is often cheaper per square foot than going out on small lots, but it costs more in total because you’re adding structural reinforcement to the existing first-floor walls and roof. In older Fort Lauderdale neighborhoods like Croissant Park or Poinsettia Heights, where homes were built in the 1950s and 60s, tying into aging framing can add $15,000 – $40,000 in structural upgrades before you even frame the new space.
- Finish level and material choices. Builder-grade finishes run $180 – $220 per square foot. Mid-grade (what most homeowners choose) runs $220 – $300. Specification-grade materials from partners like Cambria, Silestone, Kohler, and Moen push you toward the top of the range. The good news: you choose, and we price it in writing before we start.
- Permitting timeline and city review. The City of Fort Lauderdale’s Building Services division requires full architectural and structural drawings for additions, plus zoning review. Permit fees themselves are modest ($1,500 – $6,000), but the review process can take 4 – 8 weeks. That’s time, not money, but it affects your project schedule and can influence contractor availability pricing during peak season.
Home Addition Cost by Project Type in Fort Lauderdale
Not every “addition” is the same size or scope. Here are the specific project types we see most often in Fort Lauderdale, with the numbers attached:
Bedroom Addition
Adding a single bedroom without a bathroom typically runs $45,000 – $75,000. This includes foundation, framing, roofing tie-in, electrical, drywall, paint, flooring, and impact windows. In neighborhoods like Lake Ridge or Dorsey-Riverbend, where lots are smaller, we often recommend a second-story bedroom addition over a ground-level bump-out to preserve yard space. Expect that to run $65,000 – $95,000 because of the structural work involved.
Primary Suite Addition (Bedroom + Bathroom + Walk-In Closet)
This is the most common home addition project we do in Fort Lauderdale, and it typically costs $85,000 – $130,000. The bathroom is the cost driver: plumbing rough-in, waterproofing, tile, vanity, shower glass, and fixtures. Using Kohler or Moen fixtures and a mid-range tile package, you’re looking at $9,000 – $28,000 for the bathroom portion alone, which mirrors our standalone bathroom remodeling pricing.
Second-Story Addition
A full or partial second story runs $110,000 – $250,000+ depending on square footage and whether you’re replacing the existing roof entirely. These projects are increasingly common in Fort Lauderdale neighborhoods like Idlewyld and Nurmi Isles, where waterfront lot sizes are locked and the only way to add square footage is to build up. Roof replacement alone, integrated with the new second story, runs $8,000 – $20,000 on the existing structure.
Bump-Out Addition (Kitchen or Living Room Extension)
Extending an existing room by 6 – 12 feet costs $50,000 – $90,000. These projects are less expensive per square foot because you’re extending existing walls rather than building an entirely new room envelope. But they still require foundation work, roofing tie-in, and usually some reconfiguration of the existing space. If the bump-out expands a kitchen, add $14,000 – $45,000 for the kitchen remodel work inside the new footprint.
Garage Conversion
Converting an attached garage into living space runs $30,000 – $80,000. This isn’t technically an addition in the structural sense, but Fort Lauderdale homeowners often ask about it as an alternative. The big cost variable is bringing the space up to code: slab insulation, ceiling height requirements, impact-rated door replacement, and HVAC extension.
ADU Construction
A detached accessory dwelling unit costs $90,000 – $220,000 in Fort Lauderdale. These are fully permitted structures with their own electrical service, plumbing, and often a kitchenette. Zoning rules have gotten friendlier in recent years, but setbacks, lot coverage limits, and utility connection requirements still vary by neighborhood. Call us before you assume your lot qualifies, and we’ll tell you straight.
How to Save on Home Addition
Home additions are expensive, but there are legitimate ways to keep the number down without cutting corners on structure or safety:
- Keep plumbing where it already is. The cheapest addition is one that doesn’t require running new sewer lines or water supply across your lot. A bedroom or office addition costs substantially less than a bathroom addition because there’s no plumbing rough-in. If you can add square footage without adding a wet room, you’ll save $8,000 – $20,000.
- Choose a bump-out over a full second story. If your lot allows it, extending outward costs less than building up. The structural engineering for a second story in Fort Lauderdale’s wind zone is significant, and retrofitting existing walls to carry the load adds cost. A ground-level bump-out avoids most of that.
- Phase the finishes. Build the shell and rough-in now, finish the interior later. This lets you spread costs over 12 – 18 months. You still get a weather-tight, permitted addition, but you control when the tile, trim, and fixtures get installed. Some Fort Lauderdale homeowners do this to stay within a budget while avoiding price increases on materials.
- Get your drawings right the first time. Change orders are where budgets go to die. Every change after permit approval triggers re-review fees and schedule delays. Spending $4,000 – $12,000 on proper architectural drawings up front saves you multiples of that on the back end. We insist on complete drawings before pricing, and that’s intentional.
- Use our written price to shop honestly. When you call Mason Remodeling Co Fort Lauderdale for a free estimate, you get a written price, not a verbal ballpark. That number won’t move unless you change the scope. Knowing your real number before you commit means you won’t be forced into “while we’re here” upgrades you didn’t plan for.
We also spec materials at the grade you choose. If you want Cambria countertops and Toto fixtures, we’ll price them. If you want mid-range options that still perform, we’ll price those too. The point is you decide before work starts, and the written price reflects exactly what you chose.
Fort Lauderdale Home Addition Timeline: How Long Does It Take?
Most home additions in Fort Lauderdale take 4 – 8 months from permit approval to final inspection. Here’s the realistic breakdown:
- Design and drawings: 3 – 6 weeks
- City permit review: 4 – 8 weeks
- Foundation and slab: 2 – 4 weeks (longer if elevated or pile-supported)
- Framing and roofing: 3 – 6 weeks, weather permitting
- Rough-in (electrical, plumbing, HVAC): 2 – 4 weeks
- Drywall, paint, flooring, trim: 3 – 6 weeks
- Final inspections and close-out: 1 – 3 weeks
Hurricane season runs June through November, and it genuinely affects scheduling. Roofing tie-ins and exterior work can be delayed by weather windows. A project that starts in January often finishes faster than one that starts in August, simply because the exterior work happens during drier months. We don’t rush inspections or skip details to hit a date. The 365-Day Done Right Promise means we’d rather take an extra week now than come back to fix something later, on our dime.

FAQs – Home Addition Cost
How much does a home addition cost per square foot in Fort Lauderdale?
Home additions in Fort Lauderdale run $180 to $350 per square foot in 2026. The low end applies to simple ground-level bump-outs with builder-grade finishes. The high end covers second-story additions, primary suites with bathrooms, and projects requiring elevated foundations in flood zones. Most mid-grade additions land around $220 – $280 per square foot. Call (754) 354-3720 for a written price on your specific project.
Is it cheaper to build up or out in Fort Lauderdale?
Building out (ground-level addition) is cheaper per project in most cases, running $45,000 – $90,000 for a typical bump-out or single-room addition. Building up (second story) typically costs $110,000 – $250,000+ because of the structural reinforcement, stair construction, and roofing work involved. However, on small lots where yard space is tight, building up may be the only option that preserves usable outdoor space. We can price both options for you.
Do I need a permit for a home addition in Fort Lauderdale?
Yes. Every structural home addition in Fort Lauderdale requires a building permit from the City of Fort Lauderdale Building Services division, along with architectural drawings and structural engineering. Permit fees and impact fees typically run $1,500 – $6,000, and review takes 4 – 8 weeks. Any contractor who suggests skipping permits is putting you at risk with your insurance company and any future buyer. We handle the full permit process as part of every project.
How long does a home addition take in Fort Lauderdale?
Plan on 4 – 8 months from permit approval to final inspection for a typical home addition. Single-room additions without bathrooms run toward the shorter end. Primary suites with bathrooms and second-story additions run longer. Hurricane season (June – November) can delay exterior work like roofing tie-ins and window installation. We’ll give you a realistic schedule before we start, and we don’t cut corners to hit a date.
How much does it cost to add a bathroom as part of a home addition?
Adding a bathroom into a new addition costs $9,000 – $28,000 on top of the base addition cost. This covers plumbing rough-in, waterproofing, tile, fixtures, vanity, and shower or tub installation. A walk-in shower alone runs $4,500 – $12,000, while a tub-to-shower conversion in the new space runs $3,500 – $10,000. The total for a bedroom-plus-bathroom primary suite addition in Fort Lauderdale typically lands between $85,000 and $130,000.
Will a home addition increase my Fort Lauderdale property taxes?
Yes. When you pull a permit for a structural addition, the Broward County Property Appraiser’s office will reassess the improved value of your home. The added taxable value is typically based on the construction cost minus depreciation, and it phases in over several years. Most Fort Lauderdale homeowners see an annual tax increase of roughly 1.5 – 2% of the addition’s total cost. We recommend budgeting for this before you commit, and we’re happy to walk through it when you call.
Can Mason Remodeling come look at my house and give me a real price?
Yes. We provide free estimates on every home addition project in Fort Lauderdale. Call (754) 354-3720 and a live person will answer, any time of day or night.
