Can You Install a Water Softener in a Condo [Expert Guide]

Are you considering installing a water softener in your condo? Many people wonder if it’s possible to enjoy the benefits of softened water in a condominium setting. In this article, we’ll explore the answer to the common question, “Can you install a water softener in a condo?” We’ll also discuss crucial considerations and potential challenges you may encounter during the installation process. So, let’s dive in and discover how you can enhance your water quality within the confines of your condo.

My Opinion:

Can you install a water softener in a condo? The installation of a water softener in a condo can be feasible, but it requires careful consideration of several factors, which I am going to discuss below:

Review Condo Association Bylaws:

Before starting on any plumbing modifications, it is crucial to check your condo association bylaws or rules. According to a survey by the Community Associations Institute (CAI),  condo associations have restrictions on plumbing modifications. These restrictions may include requiring board approval for any changes to the plumbing system, as well as specifying the types of modifications that are allowed.

In the case of water softeners, some condo associations may prohibit their installation altogether. This is because water softeners can add additional strain to the plumbing system and can potentially lead to leaks or other problems. Additionally, some associations may be concerned about the potential for water softeners to discharge brine, which can be harmful to plants and other landscaping.

For these reasons, it is essential to seek permission from the relevant authorities before proceeding with the installation of a water softener. Failure to do so could result in fines or even legal action.

Address Space Limitations:

The next step is to address the space limitations. Condo units often have limited space compared to houses. When considering the installation of a water softener in a condo, it’s essential to ensure that you have adequate room to accommodate the unit and the associated components, such as the brine tank.

Here are a few considerations I recommend to keep in mind regarding space requirements for water softeners in condos:

A. Assess Available Space:

Start by assessing the available space in your condo where you plan to install the water softener. We have previously discussed the installation process for garage as well. Consider the dimensions of the area, including height, width, and depth. Take note of any obstructions or limitations that may affect the installation process.

B. Consider Space-Saving Alternatives:

Given the limited space in condos, you may want to explore space-saving alternatives to traditional floor models. Two options worth considering are counter-top softeners and wall-mounted softeners.

  • Counter-top Softeners: These compact units can be placed on a countertop or a cabinet. They are designed to be smaller and more portable, making them suitable for condos with space constraints.
  • Wall-mounted Softeners: These units are mounted on the wall, saving valuable floor space. They typically come with brackets or mounting kits for secure installation. Wall-mounted softeners can be a convenient option if you have limited floor space but sufficient wall space.

C. Measure and Plan Installation:

 Once you have determined the type of water softener that suits your space requirements, measure the available space accurately. Ensure the chosen unit and brine tank dimensions fit within the designated area. Take into account any necessary clearances for maintenance and accessibility.

D. Professional Consultation:

 If you need more clarification about the space requirements or the best type of water softener for your condo, consulting with a plumbing professional or a water treatment specialist may be beneficial. They can assess your situation and guide you on the most suitable options based on your space limitations.

Access to Water Supply Lines:

The next step is to access the water supply lines. To install a water softener, you’ll need access to the building’s main water supply lines. This aspect may require the assistance of a professional plumber who can work with you to ensure a proper and efficient installation. And believe me; there are so many benefits of it. 

Firstly, a plumber with experience in water softener installations can accurately assess the existing plumbing infrastructure. He can determine the most suitable location for the softener unit. They will consider factors such as accessibility, proximity to the main water supply, and the availability of electrical connections if required.

Additionally, a professional plumber can ensure that the installation adheres to local building codes and regulations. Plumbing codes vary from region to region and may include specific guidelines for water softener installations. By consulting with a plumber, you can rest assured that the installation will meet all necessary requirements, preventing potential issues and ensuring compliance with local standards.

Drain Connections:

Another component of this installation process is about assessing the drain connections. When a water softener undergoes regeneration, it flushes out accumulated minerals and impurities from its resin tank. This process generates a significant amount of wastewater called regenerated water, which needs to be appropriately drained.

For this purpose, you can either take the assistance of a water professional, or if you are good with DIY equipment, you can do it too!

But if you ask me, I’ll recommend you to take the recommendations of a professional for your condo.

Consider Shared Water Meters:

In some condo buildings, I have seen that they have a single shared water meter for the entire building. If this is the case, installing a water softener may impact your water bill, as the benefits of soft water won’t be experienced by other residents. It’s essential to consider this aspect and evaluate any potential billing implications before proceeding with the installation.

And honestly, if you ask my opinion, I would suggest you to explore the option of sub-metering. Sub-metering involves installing individual water meters for each unit within the condo building. This allows for accurate measurement of the water usage attributed to each unit, including the water consumed by the water softener. By implementing sub-metering, residents who choose to install a water softener would be responsible for the associated costs, ensuring that the financial burden is distributed fairly.

Maintenance Accessibility:

The last factor to consider is about maintenance accessibility. When installing a water softener in your condo, it’s essential to consider how you’ll access the unit for maintenance, repairs, and replenishing salt. 

For this, I will recommend you to assess your unit’s layout and ensure that there is a convenient and easily accessible location for the water softener within your living space.


To summarize, before installing a water softener in your condo, reviewing the association bylaws for potential restrictions is crucial. Consider space limitations and choose compact alternatives. Ensure access to the building’s water supply lines and plan for proper drainage. In cases of shared water meters, explore fair cost distribution options. Lastly, maintain easy access for future upkeep and repairs. These proactive measures will help you successfully integrate a water softener into your condo while avoiding potential legal issues and inconveniences.
