What do inspectors look for at Rental Property License Inspections?

What Do Rental Property Inspectors Typically Look For? 

The Basic Business License Safety inspection aims to ensure that rental properties comply with the District of Columbia Building and Property Maintenance Codes. Although the Department of Buildings (DOB) publishes its own one-page checklist, everyone has complained that it is not comprehensive and does not include all the things inspectors may look for at an inspection. Truthfully, there is no checklist that could easily be developed due to the number of pages in the code. That said, we've developed this more in-depth article based on our years of handling inspections and collecting a lot of information about what causes a property inspection to fail.


DISCLAIMER: RentJiffy does not and cannot guarantee that your rental property will pass inspection based on this document. Building codes and regulations change from time to time and without notice to us. Additionally, we are not an architecture firm, contractor, or home inspector, and we cannot provide advice or counsel on how to fix/repair items to meet the code.  You should consult your own architect, contractor, home inspector, or handyman to ensure your property meets the most current version of the building codes. 


Like most U.S. cities, counties, and states, the District of Columbia has adopted and enforces the International Codes developed by the International Code Council. These guidelines do not cover all of the more detailed electrical, plumbing, and other building codes used by professionals, but they do generally cover the majority of codes that need to be met in order to rent your unit. Below is a list of the current limitations and requirements as of the date of this article.
