It depends on your governing docs. There is no law that regulates that. If it's not spelled out in your documents that board should decided how it will be treated. The key that it should be treated the same for everyone. By the way door is different from a lock. For example you may decide that the door is owned by association (common area) but locks are owner's responsibility and have an arch standard on what kind of locks they can use to replace.

We have 6 units - two buildings one with 4 one with 2. I would consider the door as the owners responsibility, just the same as any window in the hallway

Jeff, 
 
 
 
Just curious to know why the type of lock would be regulated. /this just seems to be a bit "regulatory"!! I don't live in a condo; there may be a viable reason, but it escapes me.

A condo door to a common area is the responsibility of the HOA to maintain on the common area side. However, that is just normal maintenance, painting mostly but if the door has rotted away too. Damage to a door caused directly or indirectly by owner should be repaired by owner. 
 
Replacement of an inoperable lock is an interesting situation. In my estimation, the HOA should pay to have the lock repaired by a licensed locksmith. Most inoperable locks can be repaired. If the owner insists on a new lock, they can do so at their expense. Of course all this is predicated on the fact that the lock is the original from the builder or is a HOA replaced lock. If the current or a previous owner replaced the lock, then the cost is on the current owner because there is no way to determine if the lock is of the same quality as the original.

The only reason an association should consider regulating types of locks installed is to maintain uniformity in the building. Some associations might not care about it and it's fine. If you don't regulate it you'll end up with every color and type of locks installed. 
 
I wouldn't recommend an association to ever get involved in repairing/replacement of locks. Not only it creates unnecessary burden for the association, but it may also provide with added liability. I can see an owner suing association for poor quality of a locks if there is a robbery.

Thx, Jeff! 
 
 
 
Frankly I think too many BOD's get caught up with the "uniformity" aspect. I will agree that some things should be uniform; but locks? Who cares what color a lock is or what brand or style? For that matter who even cares if you have a lock? <G> It surely doesn't add to property value!!  
 
However, the real problem here is not having rules that outline who is resp. for what. I would recommend the BOD passing rules addressing those components that are not spelled out in the community documents.  
 

Mary, I agree with you. It shouldn't be regulated for the sake of imposing another rule. Too many powere hungry HOAs just love doing that. With that said some buildings are more uniformed than others and it should be considered. 
 
Another reason to limit types of locks is to make sure that they are ll safe. I once saw a kid running down a hallway and running into on of those large handles that is like a lever. It was pretty bad. Ultimately nothing bad happend, but ih was just a little shorter it might have been in his eye.

Jeff, 
 
 
 
I thought there might be some reason; but as I said, living in a single family home I just couldn't think of one.

I asked the question because within the 4-plex hallway the OWNERS are responsible for cleaning (service) and maintaining the aesthetics of that area -- which I have heard is called "limited" common area -- it's not a common area, i.e., pool, clubhouse, green areas, etc. There is a common outside door (no lock) and we know(that) is Association's responsibility to maintain. Their hallways are private so the area could be designated as "limited" common area (is the way I see it). 
THANK YOU ALL FOR YOUR INPUT. Maintenance man installed lock but not the door handle. I live in a townhouse and when my lock broke I put in new parts and paid for it myself.
