Well, this depends on whether you have a house or you are living in an apartment.

For people who have their own houses, a lot of them decide to put the hot tub in the back yard. However, if you are thinking of putting your hot tub in the front or back yard, question yourself whether you will use it during winter or not. You will not want to rush into your house after soaking in the cold weather.

If that is the case, the best option is your deck. It should be capable of holding 90 pounds on one square foot. Older decks can use some reinforcement with a few 4-bys and extra stringers.

If you are living in an apartment, you should not place it on the balcony regarding potential leaks which can damage the building. You should hire a trusty structural engineer to do the work for you.

However, if you really want to put the hot tub outside on the balcony with an amazing view of the city, there are still some solutions. But first and foremost, your balcony has to be made from reinforced concrete with steel L beams inside.

It is rather complicated to tell what is inside the concrete without expensive testing. Therefore, you should find out the time when they built your balcony and look up the constructive requirement at that time.

Maybe that will bring you some ideas because older structures cannot keep up with modern standards.
