Towing Issues: Towing in an apartment complex, apartment manager, spaces and places

Question
I live in West Los Angeles (90048) and my building has a sign posted for a tow service that does not exist.  The sign says no-parking.  People park in this area all the time and block me in my spot with no way out.  The building manager says residents can't tow AND that even if we could the person would have to be in the spot for 90 hours?? This can't be true and what am I supposed to do when I get blocked in?

Answer
Well, the manager is right and wrong...  First of all the outdated tow sign is not good but most places like them for the "implied warning " that they offer...

Now California recently (Jan 1 2007) revised the rules and regulations for towing of vehicles from private property.
Now the manager is correct that TENANTS can not order tows, as only the property owner and or manager can authorize tows.. Now there is also a provision where the person ordering the tow can be held liable if its an invalid or illegal tow for the fees and a penalty.. Something to think about there..

The parking in the space for 90 hours is wrong, there is also a provision for 1 hour  but it also has exemptions for apartments ...  Now if the people are parking in spaces and places that do not allow you to get in or out then there should be something done about it..   

I would ask the apartment manager to contact a "quality " towing company (yes there are a lot of them that are a bit shady in the business practices ) who deal with private tow aways..  They can help the manager get things resolved and set up to LEGALLY do the tows from the property...
