While 10 miles isn't much you also have to consider the conditions. If in a downtown urban area, how is the day-to-day threat? It will likely be worse if the SHTF is a race-riot, Antifa protest, major power outage, terrorist attack, etc.
Weather will be an impactor. Winter and summer will have debilitating affects if not properly dressed or hydrated; hot weather seems to bring out the crazy in many people. While you should be able to trek home easily with very little, you may get a late start, get delayed, or have to reroute and extend the distance. It seems like most disasters kick off at the end of the day and could delay you to the point you may have to navigate at night. A flashlight is critical, especially in an urban area. Even deep inside a factory, a major power outage can turn into disaster trying to navigate with no illumination.
I would have some blue-collar clothes common to the area on hand, a case of water at work. Keep a light on your body and if possible a handgun (or at least in your vehicle or office). With an urban environment, you have additional threat vectors: fire, smoke, dust, falling debris, rubble, exposed rebar, sharp objects, broken glass, spilled fluids, raw sewage, electrical hazards, etc. Consider even a simple dust/smoke mask, leather gloves, eye-protection, and study shoes/boots.
Have a radio or pay attention to whatever the disturbance is and have a map of your city. A quick walk into the middle of a riot wouldn't be advisable, but a scanner could help avoid such areas. Some roads my be blocked or are medical triage areas that you won't be able to traverse.
A good book to consider is
How to Survive Anywhere by Christopher Nyerges
Back when I was on Active Duty several years ago, I had a job where I traveled a lot here in CONUS and mostly to cities where we had bases. I built a kit I could travel with when using my truck or a rental car (used a downsized kit when flying). Mine was pretty robust, but you can streamline with much of what I recommended above.
