I’d certainly request - in writing - explanation from the HoA board. Also, you ought to be able to identify whether you own a particular parking space and, if so, where it is.
Does the HoA hold regular meetings? I would send mail to all officers of the HoA, and ask for a response within a specific time - maybe 10 days, maybe a month. How long ago did you email the people - and who are they?
You don’t explain what parking is like. I’m having a hard time figuring out how this is configured - what a “parking space in front of the road” is, or how the property line “makes a slight turn” to create the parking space. Is this a situation in which people are regularly vieing for parking spaces? Is “your” space numbered or otherwise identified as going with your unit? Is the 1’ smaller space still ample for your needs? If it was moved, do you now encroach on someone else’s space? Did more people than you have their spaces moved/shortened? How clearly is the parking space defined? Specific measurements, or simply in general terms, like, “the parking space closest to the front door.”
I tend to be pretty anal about surveys and property matters. If a space of a certain size is deeded to you, you paid for it. It should not be relocated or reduced by an inch - let alone a foot - without good reason, compensation, and your agreement. It may seem minor - but someone is essentially trying to take some 10 sq feet of property from you. If it were up to me, I’d prefer that someone give me 10 MORE feet than take 10 feet away. You’ll also have an (admittedly minor) potential issue should you go to sell - your apparent space will not conform with the survey. Or when a neighbor - whomever owns an adjoining spot - sells and a new survey is done.
I would expect your deed to be pretty specific as to exactly what space you own. I would also look into your state’s laws regarding condos/HoAs, to see what is required of the board, and what might be done about parking.
In a weird way, the deed probably still controls. Your space remains where it originally was (presuming it was correctly marked before.) Someone repainting the lines (or putting up a fence) does not change the boundaries of your property. So you probably could just keep parking where you previously did - tho that would likely cause confusion.
I assume this was a mistake rather than some nefarious plot. But who knows? Maybe the HoA board tried to shrink all the spots to gain space elsewhere. Unless the HoA TOLD the contractor to mark the spaces differently, the contractor fucked up, and should be required to correct their error. And if the HoA failed to adequately supervise or something, well, they probably have insurance, or should otherwise have to eat the repainting out of reserves.
It is too early to start hiring a lawyer. But I would definitely pursue answers from the HoA. And I would escalate my efforts if they failed to respond.
I’m very surprised your friend, the property lawyer, would say it is no big deal because it was simply moved. What if they moved it significantly further from your home? Or underneath a tree that dripped sap? Only you can decide how big of a deal this is to you. But there is a lot of stuff that is vague and impermanent these days - and the boundaries of and rights to deeded real property ought not be among such things.
