Is It Safe to Leave Balcony Door Open?

Balconies are little chunks of the outside world in your apartment.

You can decorate your balcony as you wish, make it a nice sitting space, and look at the horizon from your high-rise apartment.

Another reason why you probably love your balcony is because of the nice, cool breeze that comes in at night. However, is this breeze really worth it?

It might be tempting to leave your balcony door open at night when you sleep because of the fresh air that comes in.

It also prevents you from feeling enclosed and suffocated. But is this a safe practice, though?

Is It Safe to Leave the Balcony Door Open?

The simple answer is no; it is not safe to leave your balcony door open.

If you have your eyes on the balcony and are sitting in its line of sight, then sure, it could be a good idea, but if you do not have your eyes on the balcony, such as when you are asleep, then you should not leave the door open.

Now, we are not saying that something bad will happen if you leave the door open.

In fact, the chances of something happening are always less than those of something not happening, but there are just far too many risks involved.

It’s better to be safe and keep the balcony door closed, especially when you are asleep or not at home, to prevent any mishaps or accidents from occurring. 

Why Should You Not Leave Your Balcony Door Open?

There is a myriad of reasons why leaving your balcony door open is a bad idea at night or when you are asleep. Here are some of the reasons:


Naturally, the biggest concern anyone has regarding leaving their doors open is the chance of a burglary happening.

Even if you live in a safe area, a robber will only see the open balcony door as an invitation.

When you are asleep, not home, or just away from the balcony, someone can strike, and it will not be a pleasant experience.

People living in high-rise buildings on very high floors might think that they will not have to deal with burglars since they cannot climb that high.

However, no matter how high up your apartment is, it will not be 100% safe if you leave the door open since robberies have evolved and burglars have also found unique ways to strike their victims’ houses.

One of the ways that a burglar can gain access to your apartment high above is through the roof.

If the robber makes it to the roof of the building, they can use methods of suspension to land on any balcony they want, including yours.

Now, this is definitely a scary thought to envision, but it is all the more reason to lock your balcony doors at night! Prevent any possible situation for the safety of your home! 

Pet Safety

Another reason why you should keep the balcony door locked is for the safety of your pets.

Pets can be really unpredictable. Your cats can have the zoomies; your bird wants to fly around the hours, and your dog is always excited to be let out.

And while your pets should enjoy some time on the balcony and sunbathe and relax a little, this should only happen under your supervision.

The balcony might contain dangerous objects or have sharp corners, which pets can get hurt on.

Furthermore, if they are really excited and running around the house, they might even jump off the railing.

It would be very devastating to lose your pet this way, especially if it happens while you are not looking or asleep.

The reasonable thing to do is to keep the door locked and prevent the little critter from escaping!

Child Safety

Babies have similar issues to those of pets. If your baby crawls or has started walking, the balcony could be a dangerous space for them.

Just like the pets, the baby might hurt itself on a sharp corner or anything you have put out on the balcony.

They might end up eating leaves from a plant you have left out on the balcony. Even if the plant is not poisonous, it is not really advised for babies to eat leaves and such!

Other than that, if you have an open railing, your child might be at risk of falling over too.

As children grow older, they get smarter and more curious. So the baby might even find a way to climb the railing, which could threaten your child immensely.

All of this could also happen when you are asleep or not keeping an eye on your baby. Babies are actually much faster than we think they are!

So keep the balcony door locked and closed to keep your child safe from these accidents. 

Animal Entries

Like we said before: The balcony is like a little portal to the outside world in your house.

The outside world has sunlight and fresh air, but it also has wild animals!

There are so many cases of birds like pigeons and crows entering houses.

Now, while neither of these animals is particularly dangerous, they can be a nuisance if they enter your house and cannot leave.

Sometimes birds also slam into ceiling fans and sharp objects, which ends up being fatal for them.

We are sure you do not want the blood of an innocent bird on your hands either now!

However, even more threatening wild animals such as eagles, mice, and raccoons can enter your house if you leave the balcony open.

The raccoons and mice are especially a problem if you live closer to the ground since they can easily climb up.

You do not want your home to be infested by mice or raccoons, now would you? If not, then you should really close the door whenever you do not have a watchful eye on it.  

Accidental falls

Now, this point may seem redundant, and the chances of an accidental fall like this are usually slim. But people can fall over from the balcony when they are not fully conscious.

This means if you or someone in your home has a habit of sleepwalking, you can easily walk out the door and put your life in danger.

Of course, if you are used to your house, it probably won’t be too hard to open the balcony door even if it is locked, but it is still quite a safety precaution!

An added burden for someone who wants to walk out of the balcony under the influence.

Alternatives To Closing Balcony Doors

The great news is that there are some things you can do instead of keeping your balcony doors closed.

While none of these methods is 100% safe, they still provide ample safety if you want to keep your balcony door open at times.

Install Netting

The first thing you can do is install netting over the railing of the balcony.

The netting should be attached from the roof of the balcony, all the way down to the railings, covering all the open parts.

Now, depending on how big the netting is, small animals such as mice might still be able to enter easily.

However, you will prevent your pets from falling over, you will restrict some access to any potential robbers since the netting will be a deterrent, and robbers will probably not want to deal with big hurdles when they have the plan to hatch.

The netting will also prevent any animals from outside from entering the balcony as well.

Remember that some animals like mice are able to chew through thinner nets, and you will probably need something sturdy to prevent these little critters from getting inside your house.

Get a Screen

The screen will serve a function that is very similar to that of netting.

Screens have an advantage since they restrict visibility to a great extent while still allowing fresh air and sunlight to come to some extent.

However, screens also restrict your visibility to the outside world, which might ruin the purpose of a balcony.

Metal Grills Or Mesh

Installing grills or meshing on the balcony is another great way to prevent your children or animals from escaping and preventing something (or someone) else from entering.

These grills also keep the outside world visible to you and allow sunlight to come in as well.

Glass Panels

Many modern balconies have glass panels covering the whole area. These panels keep the balcony safe while still letting you look outside.

They will block your access to fresh air to a great extent, though.

Safety Considerations

When it comes to leaving balcony doors open, there are several safety considerations that we need to bear in mind.

In this section, we will discuss the security risks, fire hazards, accidents, and dangers associated with leaving the balcony door open.

Security Risks

Leaving the balcony door open could be an invitation for burglars to enter our homes.

Even if our balcony is located on an upper floor, experienced burglars can find ways to climb and gain access. 

Home security is essential to avoid burglaries and protect our valuables.

Additionally, wild animals like raccoons or other pests could easily make their way into our homes, causing damage and potentially endangering our pets or children.

Fire Hazards

An open balcony door may pose a fire hazard in some circumstances. For instance, it could let in hot air, which can increase the likelihood of fires starting inside our homes.

Moreover, in the event of a fire, an open balcony door may allow smoke to spread more easily through our homes, endangering our loved ones and increasing potential damage.


Accidents can happen around the balcony, especially when the door is left open. A strong breeze may cause the door to slam, injuring us or damaging the door and its surrounding area.

Also, with the door open, there is a higher likelihood of accidental falls, especially for children or toddlers who might wander out onto the balcony.

Ensure that balcony railings are secure and high enough to prevent such accidents.


There are other dangers associated with leaving the balcony door open as well. For example, if we live in an area prone to strong winds or storms, leaving the balcony door open may expose our homes to these weather-related risks.

Insects and pests may also enter our homes, causing potential harm to us, our pets, or our personal belongings.

Furthermore, the performance of services like air conditioning or heating systems may be affected, putting pressure on these appliances and potentially raising energy costs.

Ventilation and Air Conditioning

When considering whether to leave a balcony door open, it’s important to weigh the potential benefits related to ventilation and air conditioning.

Fresh air and natural breezes can be inviting, but there are also some concerns to consider.

One advantage of keeping a balcony door open is increased ventilation in your living space.

Allowing a fresh breeze to enter your home helps improve the air quality and can potentially help prevent the spread of viruses in indoor spaces.

However, it’s essential to ensure that the outdoor air quality is safe and free from pollutants.

You should also be aware that open doors can sometimes invite pests or compromise the security of your home, as mentioned in this article.

When it comes to air conditioning, leaving a balcony door open can have a significant impact on the efficiency of your AC system.

Most AC systems operate on a thermostat, which means they’re designed to adjust the temperature based on the room’s environment.

Leaving the door open could interfere with your AC’s temperature control, causing it to work harder and consume more energy to maintain the desired temperature.

Some strategies we can suggest for maintaining a balance between ventilation and air conditioning efficiency include:

  • Closing your balcony door when the AC is running, to help reduce energy consumption and maintain the desired temperature.
  • Turning the AC off and opening your balcony door when outdoor air quality is good, to let in fresh air and save on energy costs.
  • Installing a ventilation system to help improve indoor air quality while maintaining optimal temperature control.

In summary, leaving a balcony door open can have both benefits and drawbacks concerning ventilation and air conditioning.

It’s essential to consider the security, indoor air quality, and energy efficiency of your living space while making this decision.

Privacy and Decoration

When it comes to our balcony doors, privacy and decoration go hand in hand. As we strive to create an inviting and comfortable outdoor space, it’s essential to address the privacy concerns that can arise from open balcony doors.

Balcony doors often serve as a visual barrier between our living space and the outside world, so it is crucial to consider how securing our home also impacts its appearance.

One way to achieve both privacy and an appealing aesthetic is by using decorative and functional window coverings.

These coverings, such as curtains or blinds, allow us to control the amount of visibility into our homes while also adding a touch of elegance and design.

This approach to privacy and decoration not only maintains the security of our home but also enhances the overall ambiance.

Another factor to consider is the arrangement of our balcony furniture and decorations, especially when it comes to the view from the inside.

Aligning our furniture in a way that does not obstruct our sight lines to the horizon can improve our sense of privacy and security.

At the same time, it allows us to enjoy the beautiful scenery while keeping our balcony door closed.

To further ensure privacy, we can also incorporate natural elements into our balcony design.

Adding tall plants or trees near the balcony door can serve as a barrier against unwanted attention while still providing an attractive, natural sight.

Combining these elements with decorative features such as string lights or accent pillows can create the perfect balance between privacy and decoration.

In conclusion, it’s essential to prioritize privacy and decoration while addressing the safety concerns of leaving our balcony doors open.

By implementing the right combination of window coverings, furniture arrangement, and natural elements, we can create a secure and visually appealing outdoor space that suits our needs and enhances our overall home experience.

Wildlife Considerations

When it comes to leaving your balcony door open, it’s important for us to consider the potential impact of wildlife.

Various wild animals and birds may find their way into our homes if our balcony door is left open, creating a nuisance and potential health risks.

One significant concern is the possibility of nocturnal animals such as raccoons, bats, and even snakes entering our homes through an open balcony door.

These creatures can cause damage to furniture, and appliances, and contaminate living spaces Small Balcony.

As many of these animals are excellent climbers or can fly, height does not necessarily serve as a deterrent.

Birds are another factor we need to keep in mind. It’s not uncommon for birds to build nests on balconies or near open doors.

While this may seem harmless, nests can become home to parasites and create a mess on your balcony.

Additionally, some bird species may become aggressive in protecting their nests, which could cause a safety concern for us.

Removing bird nests is acceptable under certain conditions, such as the nest being abandoned or unsafe for future use The Spruce.

Lastly, small creatures like mice can also make their way into our homes via open balcony doors. Mice can chew through wires and insulation, causing damage and potential fire hazards.

They are also known to carry diseases that can pose risks to our health.

To avoid these wildlife-related issues, it’s essential to take preventive measures, such as using screens or nets to cover the balcony door opening while still allowing airflow.

This solution can help to minimize the risk of wildlife entering our homes, while still providing the benefits of leaving the balcony door open for fresh air.
