Converting an empty attic

If your attic is empty, it has great potential to be transformed into an entertainment area, playroom, bedroom, or even a man cave. For most of us, the only problem with utilizing this already-existing space is more or less the cost of conversion. Luckily, you already have the existing framework of the roof to work with, so costs are much smaller than adding an entirely new addition or extension to your home.

Things to consider when converting attic

Nevertheless, there are some things you still have to take into consideration before starting this project.

7s rule

It’s not obligatory, but the 7s rule comes in pretty handy when assessing your possibilities. This rule means, at least half of your attic space must be 7 feet high by 7 feet wide, with a total of 70 square feet. Keep in mind, codes vary from place to place, but for using the attic as an actual room, this rule typically applies.

Access to new space

Accessing the new room – You should consider adding a permanent staircase because pull-down stairs are often a hassle and might not work for the new room. When adding a permanent staircase, it’s important to access the layout of the floor below. Where should the stairs begin, is there enough room for them, and how much living space will it take from the floor below.

The attic staircase must

  • Provide a minimum of 6’8″ of headroom the entire walking length of the stairs.
  • Be at least 36″ wide.
  • Have treads of at least 10″ deep.
  • Have risers that are at least 7 1/4″ high.

Insulation of a roof

Planning Your Attic Remodel

Failure to comply with local building codes can lead to costly delays, fines, or redoing work. Contact us for more details about permissions with local building department and local building codes.

Insulation acts as a barrier that keeps conditioned air in and unconditioned air out. The U.S. Department of Energy recommends using insulation with a total R-value of R49 to R60

Adequate Ventilation

Attic ventilation helps with energy efficiency and prevents moisture issues. A balanced ventilation system should include both intake and exhaust vents

Heating and Cooling

You can add ductwork or vents to extend your existing HVAC system into the attic. Install a ductless mini-split system to heat and cool your attic independently

Additional Attic-Finishing Expenses

Permits

In most cases, yes, you’ll need a permit to renovate an attic. Additional living space to your home typically requires a building permit, and this includes finishing an attic.

Furnishings

Unless you have all the furniture you need for the attic already, remember to budget for what you’re actually going to put up there.

Painting

While painting yourself is one of the easiest ways to save money on an attic finishing project, it’s not crazy to want a professional job after spending so much time and money on the project.

How to Finish an Attic Step by Step

Clean Out Your Attic

Before you begin your renovation, you’ll want to declutter your attic. Start by throwing away old junk and insulation.

Wire the Attic for Electricity

Once your attic is brought up to code and you have a permit, hire a licensed electrician to do all electrical work and ensure all wiring meets code requirements.

Add Plumbing

If you’re adding a bathroom to your attic, you’ll need to install plumbing next. Again, unless you’re an experienced plumber yourself, you should hire a professional to ensure your project goes smoothly and you don’t run into any issues, like drainage problems, in the future.

Build a Subfloor

If joists are visible on the floor of your attic, you will need to build a subfloor. Add insulation under your subfloor to reduce the sound traveling between your attic and the rest of your home.

Insulate Your Attic

For a DIY project, the best insulation for an attic is batt insulation with a vapor-retardant facing. This insulation is great for finishing an attic because it is flexible, easy to install, and can even be layered for additional coverage.

Install Walls and Ceiling

Once you’ve finished installing the insulation, it’s time to finish your walls. Hang drywall horizontally from your exposed studs and secure with drywall screws.

Install Lighting and a Fan

Adding skylights or dormers to your attic is a great way to introduce natural light into your space. But if these additions aren’t in your budget, and you don’t need to add a dormer to meet building code requirements, there are many other ways to light up your space.

Paint Attic Ceiling and Walls

Next, paint your drywall. New drywall will need to be primed prior to painting. After priming, add at least two coats of paint to give the drywall a finished appearance.

Choose and Install Attic Flooring

You’re almost finished with your attic remodel! Your next step is to choose flooring for the room. Installing carpeting is a good option for an attic because it helps absorb sound and adds additional insulation to your floor.

Maximizing Your Finished Attic Space

Storage Space Ideas

Use your finished attic as a storage space, perfect for storing seasonal decorations, out-of-season clothing, or luggage.

Turning the Attic into a Walk-In Closet

Consider adding a closet organizer system to maximize storage space.

Creating a Functional Finished Attic
