Matt Owns an Apartment Building to Which Access Is Gained

Matt owns an apartment building to which access is gained through a secured entryway. Matt has repeatedly refused to allow code inspectors into the building to examine that the electrical system is up to code. What options do the code inspectors have?

A) They can access the building only if they have verified information from a tenant that there are electrical issues in the building.
B) They can seek an administrative warrant based on the probable cause standard set for a criminal investigation.
C) They can seek an administrative warrant based on a modified probable cause standard set for administrative inspections.
D) They can forcibly enter the building without a warrant since Matt is not entitled to Fourth Amendment protections against administrative inspections.
