The correct answer highlights the requirement for HUD clearance regarding multi-family housing sampling, which is centered on the principle of representative sampling. For effective clearance, it is essential to randomly select units based on the size of the multi-family dwelling. This approach ensures that the sampling accurately reflects the conditions and potential lead hazards present across the entire property rather than focusing on a single unit or specific areas.

By implementing random selection, the process can account for variations in lead presence that may not be obvious from visual assessments alone. This method not only aids in obtaining a clearer understanding of the overall lead exposure risk throughout the property but also ensures that the testing process is both efficient and comprehensive, thereby facilitating compliance with HUD guidelines. Random selection based on the number of units helps to avoid bias and adds to the reliability of the assessment results.

Other methods, such as assessing the entire unit or performing visual assessments for every unit, may not be feasibly efficient in larger multi-family settings or may not capture the variability present throughout the building. Testing only in common areas would also be insufficient, as it neglects potential risks within individual units where residents might be exposed to lead hazards. Hence, random selection is the most effective method for HUD clearance in multi-family housing scenarios.
