AfterHow Much Does Home Addition Cost in Fort Lauderdale?
A home addition in Fort Lauderdale currently runs between $45,000 and $130,000, with most single-room additions from Penhallow Remodeling landing in the $60,000 to $95,000 range. The final number depends on square footage, foundation type, whether you’re adding plumbing or a new HVAC zone, and the finish level you choose. Call (754) 551-2922 and we’ll give you a written price before any work begins, not a verbal ballpark that changes after demo day.

Home Addition Cost Breakdown (2026)
Here’s how a typical Fort Lauderdale addition breaks down, line by line. These are real working numbers from recent Broward County jobs, not national averages with a Florida adjustment bolted on.
| Line Item | Typical Range | Notes |
|---|---|---|
| Design & Permitting | $4,000 – $12,000 | Architectural drawings, structural engineering, Fort Lauderdale building permit fees. Flood zone surveys add $1,500 – $3,000. |
| Foundation & Slab | $8,000 – $22,000 | Standard monolithic slab for a single room. Pier foundations or stem-wall construction (common east of US-1) run higher. |
| Framing & Roofing | $12,000 – $30,000 | Concrete block or wood frame, trusses, tile or metal roof match. Wind mitigation requirements add cost. |
| Electrical & HVAC | $6,000 – $18,000 | New subpanel, wiring, mini-split or ducted system extension. Older homes often need a main panel upgrade, another $2,500 – $5,000. |
| Plumbing | $3,000 – $10,000 | Only applies if you’re adding a bathroom, wet bar, or laundry. Slab saw-cutting for drain lines costs more. |
| Drywall, Insulation & Finishing | $6,000 – $15,000 | Impact-rated windows and doors are mandatory in Broward County. Budget $800 – $1,400 per opening. |
| Flooring, Paint & Trim | $4,000 – $12,000 | Tile (strong choice for Florida humidity), engineered hardwood, or LVP. Baseboards, casing, paint. |
| Contractor Overhead & Margin | 10% – 20% of total | This is where a written price protects you: the number on day one is the number on the invoice. |
For a full home addition in Fort Lauderdale, the biggest swing factors are bathroom additions (plumbing + waterproofing + tile work) and kitchen extensions (countertop material, cabinet line, appliance rough-ins). A 400-square-foot bedroom bump-out with no plumbing might land around $55,000. A 600-square-foot primary suite addition with a walk-in shower, dual vanity, and walk-in closet routinely passes $100,000.
What Affects Home Addition Pricing in Fort Lauderdale
- Flood zone and elevation requirements. Large sections of Fort Lauderdale sit in FEMA flood zones, and additions must meet current elevation standards. In neighborhoods like Shady Banks and Sailboat Bend, we regularly see finished floor elevation requirements that force a higher stem-wall or raised-slab design, adding $8,000 – $15,000 over standard slab construction.
- Wind load and impact-rated openings. Broward County’s High Velocity Hurricane Zone code means every window, door, and skylight in the new space must be impact-rated or protected by shutters. That’s non-negotiable and typically runs $6,000 – $12,000 for a single room with three to five openings.
- Existing structure condition. Many homes built in the 1950s and 1960s, particularly in Coral Ridge and Victoria Park, have older electrical panels, cast-iron drain lines, or unpermitted prior work that surfaces during inspection. Bring the rest of the house up to code and you add $5,000 – $20,000 before the new square footage is even framed.
- Second-story vs. ground-floor addition. Going up requires structural reinforcement of the existing first-floor walls and roof removal, and it often triggers a full roof replacement. A second-story addition in Fort Lauderdale typically costs 30 – 40% more per square foot than a slab-on-grade bump-out.
- Finish level. Builder-grade carpet and stock cabinets might finish a 400-square-foot room at $110 – $140 per square foot. KraftMaid or Wellborn cabinetry, Cambria quartz surfaces, and Kohler fixtures push that to $180 – $260 per square foot. We install all of the above, and we’ll show you both prices in writing so you choose with your eyes open.
- Permit timeline and plan review. Fort Lauderdale’s Building Services division has streamlined some residential permits, but complex additions can still take 3 – 8 weeks in plan review. If you’re paying carrying costs or living elsewhere during construction, that timeline is a real cost.
How to Save on Home Addition
Saving money on a home addition in Fort Lauderdale is less about finding the cheapest bid and more about making decisions that reduce labor hours and material waste. Here’s what actually moves the number:
- Keep plumbing where it is. Adding a bathroom or wet bar to the far side of the house means cutting concrete, running drains across the slab, and possibly adding a lift pump. Position the new space adjacent to existing plumbing and you can save $5,000 – $10,000.
- Choose a simple roofline. Gable roofs and shed roofs cost less than hips, valleys, and dormers. Every roof angle adds framing hours, flashing, and tile cuts.
- Build up, not out, when the lot allows. In older Fort Lauderdale neighborhoods with tight setbacks like Croissant Park and Poinsettia Heights, a second-story addition can sometimes cost less per square foot than the foundation and site prep a ground-floor addition demands.
- Phase the finishes. If the budget is tight, we can frame, dry-in, and rough in the addition now, then you choose cabinets, counters, and tile in a second phase. You get a permitted, dry, lockable addition, and the expensive finishes wait until you’re ready.
- Get a written price before you commit. The most expensive additions we see are the ones where a contractor gave a verbal “around $80,000” and the final invoice landed at $115,000. We write the number down first, and you hold us to it. Call (754) 551-2922 for a free estimate and you’ll see exactly what we mean.
What’s Included in Penhallow Remodeling’s Home Addition Pricing?
Our written price covers the full scope: drawings, permitting, all materials, all labor, all disposal, all inspections, and final cleanup. It also includes something most Fort Lauderdale contractors won’t put on paper: the 365-Day Done Right Promise. If anything we built fails inside the first year, we come back and fix it at no charge. That promise is written into the contract, not mentioned in passing at the sales table.
Every Penhallow addition follows The Kingswell Way, the operating standard our company has worked under since 2004. Say the price before the work. Show up in the window we gave. Leave the place cleaner than we found it. The technicians who arrive at your door are background-checked and in uniform, and you’ll know exactly who is walking into your home each morning.
How Long Does a Home Addition Take in Fort Lauderdale?
Plan on 3 to 6 months for a single-room ground-floor addition, and 6 to 10 months for a second-story addition or a project that includes a new bathroom or kitchen. The Fort Lauderdale permitting process accounts for the first month of that timeline, sometimes longer if your property needs a flood zone variance or historic district review in communities like Sailboat Bend.
Weather is the other variable. South Florida’s rainy season, June through October, can interrupt roofing, foundation pours, and stucco work. A competent contractor plans around it, but some lost days are inevitable. We’ll give you a schedule with real dates and we’ll update it in writing if it moves.
Is a Home Addition Worth It in Fort Lauderdale?
For most homeowners, yes, but the math depends on your street and your long-term plans. Fort Lauderdale property values remain strong, particularly in neighborhoods like Tarpon River, Riverside Park, and the Las Olas corridor, where a well-built primary suite addition or a permitted garage conversion typically recoups 60 – 75% of its cost in resale value.
What doesn’t add value is a poorly documented addition. If the square footage isn’t permitted, it cannot be counted in the home’s legal living area when you sell. We handle permitting on every project, and the work passes Fort Lauderdale’s inspections before we call it done. Whether you’re adding space for a growing family or planning to sell in five years, the addition should show up where it matters: on the property appraiser’s record and in the listing.
FAQs – Home Addition Cost
What is the cheapest type of home addition in Fort Lauderdale?
A ground-floor bedroom bump-out with no plumbing is the least expensive addition, typically starting around $45,000 – $60,000 in Fort Lauderdale. A garage conversion can run $30,000 – $80,000, though you lose covered parking and the final cost depends heavily on whether the existing slab meets current elevation requirements. Call (754) 551-2922 for a written price on any addition type, free of charge.
How much does a second-story addition cost in Fort Lauderdale?
Expect to pay $180 – $260 per square foot for a second-story addition, or roughly $90,000 – $175,000 for a practical 500 – 700 square-foot addition with a bathroom. The structural reinforcement of the existing first floor, stairwell construction, and roof removal all add significantly to the cost of going up versus building out.
Do I need a permit for a home addition in Fort Lauderdale?
Yes. Every permanent addition in Fort Lauderdale requires a building permit, plans, and inspections. The permit process is non-negotiable, and unpermitted additions create serious problems when you sell or refinance. We handle the full permit package as part of every addition project. For an exact price including permitting, call (754) 551-2922.
How much does a 20×20 room addition cost in Fort Lauderdale?
A 20×20 (400-square-foot) room addition in Fort Lauderdale typically runs $55,000 – $85,000 depending on plumbing, finish level, and flood zone requirements. A simple bedroom with a closet and no water lines lands at the lower end; a home office or guest suite with a bathroom lands at the higher end.
Can you build a home addition in a flood zone in Fort Lauderdale?
Yes, but the finished floor must be elevated to meet FEMA and city requirements, which typically adds $8,000 – $20,000 to the foundation cost in flood-prone areas like Shady Banks, Riverland, and the neighborhoods along the New River. A flood zone elevation certificate determines the exact requirement. Penhallow Remodeling handles flood zone additions regularly and will include all elevation costs in your written price.
