Which option for adding animal housing space generally has the lowest construction cost?

Using a prefabricated modular facility generally has the lowest construction cost because these units are designed to be manufactured in parts off-site and can be quickly assembled at the desired location. This method reduces labor costs and the time needed for construction compared to building a new facility from the ground up. Additionally, prefabricated modular facilities can be designed specifically for animal housing needs, which helps optimize the use of space and resources while minimizing overall expenses.

In contrast, building a new facility typically involves substantial upfront investment for land, materials, and extensive labor costs associated with new construction. Renovating existing spaces can also become costly due to additional work needed to meet current standards and requirements, which can accumulate quickly. Expanding with temporary shelters may appear to be a low-cost option initially, but such structures might not offer the durability, efficiency, or regulatory compliance of more permanent solutions, which could lead to higher costs over time.
