How Much Does It Cost to Build a Balcony?

Ever considered adding a balcony to your home? Depending on your vision, the price can vary greatly. Read an expert's insights on balcony construction.
There’s nothing more idyllic than the perfect balcony. Stepping into your own private outdoor space from your bedroom or office sounds like a dream come true. While both older and newer homes are built with balconies in mind, you may want to add one to your home yourself. But how much does it cost to build a balcony for your house?
Prices can vary depending on what kind of balcony you wish to install, your location, choice of materials, and the current landscaping of your home. But what may seem as easy as adding a patio to your house can often cost much more, according to Michael Lonsdale at Lonsdale Construction. Here’s what to factor into your balcony budget.
Average cost to build a balcony
If you want a true balcony, as in a small outdoor area attached to the side of a home without support beams beneath it, be prepared to pay a pretty penny. Most balconies are built with the original house or apartment complex, Lonsdale explains. Because balconies don’t have support beams underneath them, the support has to be built into the house itself.
“Usually [a balcony] is supported by the actual joists, the framing members that also support the house,” Lonsdale says. “You see balconies, at least in California, more on apartment buildings, condos, and bigger buildings.”
He estimates that adding a true balcony onto a two-story single-family home could cost between $20,000 and $70,000, depending on a variety of factors. However, if you want to build a second-story deck that is supported by external beams, you could easily cut those costs in half.
