The Cost of Self-Storage in San Marcos, TX

Just as different regions have differing housing costs, they also feature differing storage costs. In most cases, the cost of storage is directly related to a city’s overall cost of living in general and real estate costs specifically, as the more expensive it is to buy property, the costlier it is to rent it. Monthly rental fees are also affected by the level of demand for self-storage. In cities with numerous colleges or where a high portion of the population has short-term residential leases, the demand, and therefore the price for storage, tends to be higher.

In San Marcos, the monthly rental fees for self-storage units range between $55-$210, which is considerably higher than the state range of $38-$128 and the national range of $41-$133. This relatively high cost may result from the fact that the city is home to Texas State University, a 4-year university with nearly 35,000 students. Additionally, over 70% of the city’s 64,000 residents rent their homes, which may correlate with an increased demand for off-site short-term storage solutions.

What to Consider When Looking for Storage in San Marcos, TX

When seeking local self-storage solutions, there are several factors to consider, such as the security measures the facility has in place and whether the units are climate-controlled. In areas with prevalent property crime, a storage facility with security features like surveillance cameras and high-security locks is generally preferable. Similarly, in cities that experience extreme seasonal temperatures or high levels of humidity, climate-controlled units are important for keeping personal belongings in good condition.

Compared to the national property crime rate of 35.4, San Marcos’ property crime rate is high at 43.6. For this reason, many who seek storage facilities in this city choose one with modern security features. Additionally, the city’s warm, humid summers make climate-controlled storage solutions a necessity, as high temperatures and humidity can cause permanent damage to furniture, musical instruments, artwork and other valuables.
