How Much Does It Cost to Add a Second Story to Your Home in Orlando, FL? [2026 Data]

The cost to add a second story in Orlando, FL, ranges from $81,120 to $608,400. Most homeowners pay $177,450, on average, with full-size level additions carrying the most significant costs, due to the need for structural reinforcements. Many construction projects in Orlando, FL, must also comply with hurricane-resistance requirements, which can further influence your final project cost.

Second-Story Addition Cost Factors

The cost to add a second story in Orlando, FL, depends on the size and type of your home addition as well as structural reinforcement and finish level.

Second-Story Size

A second-story addition costs between $300 and $500 per square foot on average, but complex projects with high-end materials could reach even higher.

Addition Type

When you can picture your second-story design idea but can't quite put it into words, take a look at the costs by the type of addition. Every second story will be unique, but they typically fall into one of the following categories:

• Full second story: Building a full second story over your current layout comes with stiffer foundation requirements. You will also spend more on windows, roofing, insulation, and all of the homey features that round out your second floor.

• Partial second story: These additions are popular for their flexibility and comparatively lower costs. They may include a guest bedroom, an extra bathroom, or a flexible space for an office.

• Converting a vaulted ceiling into a second story: A vaulted ceiling adds lots of airy space to a house, but some see all that space and wonder if it could be used differently. If the ceiling is higher, it’s possible to convert it into a partial addition or loft to create usable space. 

• Dormer addition: A dormer is a triangular window space on top of a roof. Dormers cost less than full second-story additions but can expand an existing second story and give rooms more light and a bigger feel.

• Add a bonus room above the garage: When adding a room above a garage, square footage matters, but you'll also need to ensure the garage's structure can handle the extra weight. The second floor may also require additional insulation and vapor barriers.

Finish Quality

If you choose higher-end materials, such as stone siding or marble bathroom flooring, expect your costs to be higher than those of builder-grade materials. While some high-end materials reduce maintenance costs, many standard finishes are still durable and save money in the total project price.

Foundation Reinforcement

Depending on the structure of your existing home, your foundation may not be strong enough to support a second-floor addition. You'll want to hire a local structural engineer to evaluate your foundation and determine what you may need to strengthen it.

Foundation support work costs $1,945 to $10,265. Where you live, seasonal weather patterns, and ground characteristics all factor into the amount of work needed. 

Demolition

In many cases, building a second story requires that your contractor remove the roof and then open up walls and ceilings to reinforce your home’s framing. Removing a room costs an average of $1,270, and the cost to replace the roof when all is said and done usually falls between $1 and $30 per square foot. While designers often work around existing chimneys, the price to remove a chimney for a second story adds an average of $4,565.

Adding a Staircase

Installing the main staircase in your home costs between $2,435 and $4,055, but high-end designs can reach $6,085. General contractors will often include this price in the second-story price estimate, as it's a crucial element of the design. However, the placement of your stairs, the design, and additional elements like carpeting can raise the price.

Landscaping

While not as common, the landscape surrounding your home may change when you add a second story. Construction equipment can damage your lawn, garden, and surrounding trees. Due to a shift in the shadows of your lawn, you may choose to move certain plants and flowers that sat in direct sun before the build. Professional landscaping costs between $40 and $80 per hour.

Temporary Housing

For safety purposes, you'll need to be out of your house during the construction of your second-story addition. A partial addition can take three to six months to complete, while a full second-story addition can take six to 12 months. If you don't have a nearby relative or a motorhome to stay in, factor in the cost of a rental into your project.

Home Builder Pro Costs

How much you’ll pay to hire a local home builder in Orlando, FL, varies according to labor and permitting fees.

Labor

Home builders and general contractors charge a fee of 10% to 20% of the total cost of your second-story addition. This fee covers their work planning and executing the construction, including hiring and scheduling crews, coordinating subcontractors, permitting, and purchasing materials. Overall, labor for home builders and construction crews will account for 40% to 60% of your final price.

With significant population growth, high demand for residential construction, and a shortage of skilled tradespeople, the labor market in Orlando, FL, is competitive. Home builders may have to pay premium rates for construction crews, and their increased overhead will likewise affect your project estimates.

Orlando, FL, also has specific requirements for homes to ensure durability against severe hurricanes. Additional work for raised or reinforced foundations, impact-resistant design and construction, and other hurricane-proofing can further add to labor time.

Taxes

The sales tax in Orlando, FL, is 6%. Home builder or general contractor services aren’t subject to sales tax, since these services are technically non-tangible. You won’t see sales tax on an individual line on your invoice, but it can still influence your costs. Home builders are considered the end consumer when they purchase building materials and supplies, so they pay sales tax and factor it into their overhead costs instead of passing it directly on to you.

Permits

You’ll need to make sure you pull the proper building permits for your second-story addition from the City of Orlando Permitting Services Division. Your building contractor typically handles this, but the cost of a building permit is $65 for the first $1,000 of project value, then $4.30 for every $1,000 afterward. That doesn’t include plan review fees, inspections, technology fees, or trade permits.

If you come up against strict laws in your area and your permit is turned down, keep in mind that you may also need to pay for legal assistance. Historic homes, homeowner associations, and areas with strict air rights can be complex to understand without a legally trained eye.

Additional Pros to Consider Hiring

Adding a second story to your home is a complex job that requires the skills of several types of professionals. Your home builder may already have some of these workers on their regular crews or on retainer, but they may also subcontract other specialized professionals, such as:

• Structural engineers: $110–$130 per hour

• Interior designers: $100–$500 per hour

• HVAC technicians: $85–$150 per hour

• Plumbers: $45–$200 per hour

• Electricians: $45–$95 per hour

Does Adding a Second Story Increase Home Value?

Adding a second story in Orlando, FL, can increase your home's value, with a return on investment (ROI) of 20% to 50%. The actual returns and home value gains depend on the added function or living capacity of the second level. In Orlando, FL, many homeowners prioritize their yard and pool area space, so building upward is a good strategy for expanding square footage. The best returns are usually for second-story home additions that increase the number of bedrooms and bathrooms.

How Angi Gets Its Local Cost Data 

To help homeowners plan their next project, Angi provides readers with carefully researched cost data and upholds strict editorial standards. We start with national average project costs, which we collect by analyzing competitor information, retailer material costs, and input from professional contractors. We then apply local price index data to calculate location-specific estimates that reflect what homeowners typically pay in their local area. To do that, we use data from the U.S. Bureau of Economic Analysis (BEA), including its Regional Price Parities (RPPs), which measure price differences across cities. This helps us account for differences in labor, materials, and overall cost of living, so estimates in higher- or lower-cost areas better reflect real-world local pricing.

Every estimate undergoes a thorough editorial review to verify accuracy, consistency, and alignment with observed market conditions.
