Anyone can go to the Land Office office on Threpasit Soi 17 and request to see land titles (chanotes). It's free or nearly so, but the queue is daunting. I haven't done that for these properties, I had no reason to do that, but I've lived here for many years and as I go around I notice what's public and what isn't. There are plenty of visual clues. The type of streetlights, presence of speed bumps, signage, and much more. I've also spoken with some who rent space in Jomtien Complex, and there have been plenty of board threads about Sunee over the years.
Property, how it's managed (or isn't) is just an interest of mine. And even though I'm not a citizen, I tend to mutter and grumble about encroachment, usually because it means I have to stumble out into traffic.
Street names and maps are a fuzzier thing here than in Peoria or Slough. In Thailand, a public street will usually have a small blue sign. I've never seen an official government map of Pattaya. Google and others show streets that are open to the public without indicating if they are actually public property.
Anyway, back to the topic, don't be concerned about Boyztown. Pushbacks on encroachment are like a hard rain in December. They are rare and don't last long.
