Finishing an attic costs $50 to $150 per square foot on average, depending on the purpose of the finished space and the level of finishing or remodeling involved. Converting an attic to a habitable living space costs the most—anywhere from $20,000 to $100,000+ depending on the size and scope of the remodel. Finishing an attic for better storage is the cheapest, starting at around $5,000, since the space is not subject to so many building code requirements.

No. You can finish some types of attics, but not all types. Some attics present major structural challenges, and some are simply not large enough to satisfy all the building code requirements to convert the attic to a living space.

• An attic with roof truss framing does not usually have enough space or structural integrity to be finished unless you completely reframe the roof. This makes the project much more costly.
• An attic with a pull-down hatch entrance cannot be converted to a code-compliant living space without installing permanent stairs connecting to the first floor. If you live in a very small home, a staircase may take up too much of a footprint on the first floor.
• Some attics are too small to finish to code, regardless of the roof framing. Many attics have sloped ceilings, and building codes require at least 50% of a room with sloped ceilings to have 7-foot ceiling height.

Finishing an attic increases a home's value when converting the attic to a habitable living space that counts as additional square footage. Including a bathroom in the finished attic tends to have the highest return on investment. Basic finishing that simply improves the attic storage space will not increase resale value, but this extra feature may still add perceived value for potential buyers.

Finishing an attic takes 4 to 8+ weeks, depending on the project scope. Converting the attic into a living space with a primary bedroom and bathroom will take much longer than a simple finishing job to create a playroom, office, bonus room, or improved storage space.

You may need a permit to finish your attic, depending on what type of finished space you're creating. Projects that involve any changes to the home's structure, electrical wiring, plumbing, or ventilation require a permit. Contact your local permitting authorities to determine the requirements for your specific project.
