Development of house rules is recommended, but not explicitly required.

The statement is true because while developing house rules is a best practice in multifamily housing, it is not mandated by law or any specific regulation. House rules serve to establish clear expectations for resident behavior, maintenance responsibilities, and community standards. They help promote a harmonious living environment and provide guidelines that can protect both the property and its residents.

However, the lack of a strict requirement means that not all housing organizations may have formal house rules established. This flexibility allows property managers and owners to tailor their community guidelines based on their unique demographics, cultural considerations, and specific community needs. Therefore, while the development of house rules is highly recommended to facilitate smooth operations and enhance resident relations, it remains a discretionary choice rather than a compulsory one.
