Which type of property development requires professional design for OSSF?

Professional design for On-Site Sewage Facilities (OSSF) is particularly critical for manufactured housing communities due to the unique challenges and regulatory requirements associated with managing wastewater in higher-density developments. These communities typically house multiple units in a confined area, necessitating a more complex and thoughtful approach to sewage management compared to single-family homes or vacant lots.

Manufactured housing communities must adhere to specific guidelines and health regulations to ensure that the sewage system can adequately handle the volume of wastewater produced by numerous homes. Consequently, professionals trained in the design and installation of OSSF systems are essential for ensuring compliance with state and local standards, optimizing system efficiency, and protecting public health and the environment.

In contrast, single-family homes, vacant lots, and detached garages may be subject to simpler permits and do not necessarily require professional design unless they exceed certain limitations or present unique site characteristics.
