House Cleaner Car Towed From “disabled” Parking Space With No Paint, Signage, Or Indicators

Location: Maryland

I am a professional house cleaner and was hired to clean a unit at an apartment complex with a large campus, parking lot, and multiple dumpsters for residents to take trash out to. I display my house cleaner flier on my dash and my spare equipment in my car is clearly visible from outside so anyone walking by has some context. I parked in the spot closest to my clients’ entrance because I have to haul my equipment inside and up stairs. I was parked for about 4 hours mid-day, with plenty of open spots and a clients neighbor called a tow on me. I know it was a neighbor, because the woman who called saw me waiting in the entryway with my equipment for my boyfriend to pick me up after I saw my car had been towed, and told me (after seeming surprised I spoke English lol) it was her who called. She also claimed she knocked on the doors of all her neighbors to ask about my car, to which I told her even if I had heard a knock (I work with headphones on) I do not answer client doors unless they inform me they are expecting a delivery or a drop in from someone. She told me it was her reserved disability spot, however there was no signage indicating a reserved spot, and absolutely no paint markings or signage or disability symbols on or near the spot at all, let alone the rest of the parking lot. There are just generic lines for spots painted, not even numbers or spot assignments for any other residents. My client and myself are both bewildered - they definitely would have advised me not to park there if they knew otherwise, and I would not have if I even thought there was a chance a particular spot was reserved. My car was in the tow yard less than an hour, and the fee to get it out was more than my day’s pay for cleaning. I figure there’s a slim chance I have any recourse here and I realize I may just have to take the L and suck it up. But I am just wondering if I have any options for contacting the apartment complex and figuring out a solution. Thanks!
