Cost to remodel an attic
To convert your attic space, you can hire an attic and loft conversions company who specialize in attic and loft conversions. You could also hire a general contractor to oversee the project. If you want to save money by doing some steps yourself, you could decide to tackle the renovation piece-meal, acting as your own general contractor and hiring specialists as needed.
A home remodeler or general contractor should provide a cost estimate for the entire project and break it down by each step. If you decide to oversee the project yourself, an attic renovation will require several specialists or subcontractors to renovate the space.
Below is a breakdown of what's included in an attic remodel, and what professional to hire if you need help with that step.

Cleaning out the attic
Before renovation, you'll need to clear out your attic. You'll need to remove your stuff, clean any water damage, damage from rodent or pest problems, and possibly remove insulation.
You can do this yourself or hire a professional cleaning and insulation service to give your attic the clean slate it needs.
Adding insulation
You will need to install new insulation to make the space habitable. Many homeowners use spray foam insulation in their attics, since it's easy to use in new construction with open and unfinished walls and attic spaces. Expect to pay between $3 to $5 per square foot on average nationwide to have spray foam injected into an existing home.
Not only is proper insulation a key step to finishing your remodel, it can also help decrease your overall heating and air conditioning costs.
Adding flooring
Many attics don't have finished floors you would want in a normal living space. You will need to install the new floors, and possibly subfloors as well. The cost of adding flooring and subfloors varies based on material.
Windows and skylights
Adding a dormer window (a roof window that projects slightly from a sloping roof) or skylight can bring natural light into the space. Dormers can also add some much-needed height and change the character of the room, taking away the typical narrow A-line look of most attics.
Adding walls and drywall
If your attic doesn't yet have it, you will need walls and dry walls. Drywall installation costs roughly $30-$60 per panel. If you're installing it on the ceiling too, double that amount.
Adding lighting
To complete your conversion of dark, dusty attic to bright, lounge-worthy loft, you'll need lights. Any electrical wiring, which includes new outlets and lights, will add to your costs.
Painting the interior
The walls are up. The floors are finished. The windows are in. Once the heavy renovations have wrapped up, it's time to put the finishing touches on by painting the walls. You could either DIY this step or hire a professional to paint your walls.
HVAC
The new room may need to be attached to the existing HVAC system for heating and cooling.
Plumbing
If you're adding a bathroom, expect to pay a plumber to install new pipes and drains for the bathroom as well as a sink, toilet and possibly a shower or bathtub.

What impacts the cost of renovating an attic?
Attic renovations require homeowners to finish an otherwise unfinished space, and is not the same as remodeling other rooms in your house. The total cost of an attic renovation includes the labor cost of contractors, inspection fees, license fees and materials.
An attic or loft conversion represents a significant outlay of money, so homeowners should consider the cost factors carefully. Below are a couple of factors that will impact your attic conversion costs:
Total square footage of your attic
The size of your attic space will affect the cost of materials and labor. Larger attics will need more materials and time to turn it into a new space.
Whether it currently meets code requirements
Depending on the current state of your attic, you may have to add additional projects and costs to meet code requirements. For example, if you need to swap your old drop ladder for a set of real stairs, a new staircase could cost you as much as an additional $10,000 for a professional to install them.
Whether you need to make structural changes
To increase functionality, you may need or want to expand your attic up or out. Even if your existing ceiling meets height requirements, you may want to change the pitch of your roof to provide extra headroom.
If you want more space, expanding over an adjacent garage or room below can be a good option. Structural changes like these can increase your attic remodeling costs substantially.
What building regulations do converted attics need to meet?
Converting an attic may seem simple — flooring, drywall, lighting, and voila, you've got a livable space. But an attic or loft conversion must meet certain code requirements. Local requirements vary and can be highly detailed, but in general they affect the following.
Total square feet
To be considered a habitable room, it must contain at least 70 square feet of usable space. That's at least 7 feet in any direction.
Staircase
Finished attics require easy access. You'll have to get rid of the drop-down stairs and install a new fixed staircase. Most codes require stairways be 36 inches wide or wider. Some local code may put restrictions on winding or spiral staircases.
Fixed and operable windows
If you're converting your attic into a bedroom, most codes require a second means of egress in an emergency, such as installing a full-size window. Building codes require fixed and operable windows meet or exceed 8 percent of the usable floor space, and that 4 percent of the square footage be windows that open to the outside.
Ceiling height
Unlike other rooms in your house, your attic wasn't necessarily built for you to stand up comfortably in. Most codes stipulate at least 50 percent of the usable finished space have ceilings at least 7 feet in head height.
Flooring
The floor joists must be stiff enough and strong enough to handle the weight of the finished space and foot traffic. Your floor should be able to hold a load of 30 pounds per square foot. This isn't an easy DIY calculation, so you'll need to talk to a pro. Your local building inspector has the final say, so check with them first.
Roof structure and rafters
Roof structure and security are another concern. Roof rafters may need reinforcement to accommodate the weight of holding the finished ceiling, lighting, electrical work, plumbing and HVAC system parts (if you have heating and air conditioning in your house).
Extending heating and air conditioning
Your home's existing heating and air conditioning system needs to be capable of maintaining a steady attic temperature of 68 degrees. Even with insulated walls and ceiling, you may need to run HVAC ductwork into the attic space.
A structural engineer can help determine what your existing attic space will need to make a renovation possible. Expect to pay around $100 an hour for this consultation. To say money upfront, you can also check code requirements with a local building official before you start. If you need additional HVAC work done to complete your remodel, here are a few cost estimates:
HVAC installation: $4,000 - $12,000 for the whole house
Intall ductwork: $100 - $250
How can you save money on an attic renovation?
If the overall renovation costs feel like a bit of a sticker shock, use some of these tips to save money on your attic conversion or renovation:
Do some of the work yourself, like cleaning, prep work, or interior painting to cut down on conversion costs. Flooring is another area that offers cost-saving DIY materials, such as carpet tiles and easy to install laminate flooring.
Look for ways to save on materials. For example, laminate flooring is less expensive than high quality wood floors.
Talk to your contractor. Talk to your contractor about your budget so they can help you choose materials and features that you can afford.
Why renovate an attic?
Renovating an attic is typically a cost effective way to add square footage and additional living space to a home. For many homeowners, the remodeling cost is less than what a new home addition would be, making it a great way to get a bonus room.
After all, if you have the roof space, an attic can be more than a dusty space for childhood toys and Christmas ornament storage. Many homeowners will convert their attic into a children's playroom, dedicated office space, combination living and storage space, workout or art studio, or an attic bedroom suite. Renovating your attic space could even be an opportunity to open up a wall and turn it into a trendy loft space.
How to hire a contractor
Finding the right contractor to remodel your attic takes a bit of work — but it's an essential step of the process. Take the time to find a contractor who has a good reputation, the necessary skills to complete the project and fair pricing. Here's how:
Search online for contractors near you. Look for attic contractors in your area, and start reading their reviews and ratings. You might find photos of the contractors' past work on their profiles, which can give you an idea of what you should have done to your attic.
Check their credentials. You should only hire a contractor who has the appropriate credentials for your attic renovation. Many states require that a contractor's license, and there might be license requirements for any professionals who conduct electrical, plumbing or HVAC work.
Ask for free estimates from several pros. As you're comparing contractors online, reach out to them for estimates. You'll need to give them information about your project in order to get an accurate price.
Get everything in writing. Before you hire a contractor, make sure there's a written contract. The contract should include details about the price, materials, timeline and more.
