There are many things to consider when planning a commercial renovation. Make sure you include your emergency exit lighting system. Though we never want to assume the worst, it's best to be prepared. And being prepared could save time and money when applying for your building permit.
Plan logical and efficient exit routes, map them out, and ensure that they will be well-lit. Inspect any remnants of your old system that will remain in use. Check power sources and connections. If the main power source to the property fails, will your exit signs and route markers be illuminated? Are your light bulbs in good shape? Would there be any benefit to upgrading to an LED system?
