Coincidentally I read about this a couple days ago, users above a certain level can actually request a new pokestop be added to the game. You get one request per day, and can let them pile up. You do need to actually walk or get somehow to the place you're requesting, so your phone's GPS can send the correct coordinates, you send a photo and a brief description and if it passes community review and isn't too close to other stops already in the area, it'll be added. Places inside private property won't pass muster but 'public' places like churches, parks, statues or other recognizable landmarks are ok.
All of that said, it's a testament to how 'dead' Pokemon go is, when no one in the user base has ever thought of submitting 14 Branchland as a stop before for laughs. Or maybe they already did and the request did not pass muster for whatever reason, most likely being 'random house does not count as a landmark'
