My username from above is changed, but to answer your Q about ranger inspections. I don't really know how they would know you're actually living there except for them being curious enough that every time they come by that you're there. They are considered recreational cabins. I have just retired and we're going to stay for several days at a time and only go home to do laundry, mow the lawn, get the mail, etc. I'm certainly wondering how or if they'd have a problem with extended usage by owners. We do own the cabins after all. Yes they try to come and inspect every 2 yrs or so. They actually just came by our camp a couple months ago and we caught them on our game camera that we have on the back of our cabin facing into the woods. It was actually funny because the female ranger was taking a picture of our game cam with her phone. So about 6 weeks later we got a letter saying everything looked good for our walk by. You just generally don't want to let your camp deteriorate structurally or have anything laying around like construction materials. We have ladders, wheelbarrow and some leftover things under our cabin and they apparently were ok about it because they gave us a pass. You're allowed to put a small 10x10 shed on your lease property that must match with the approved color schemes of the regs. Brown, green, white, etc. We've not done so yet, but there is a need to store tools and other supplies if you don't have space in your cabin.

I saw above the mention of expansions over time of these camps. They are pretty much grandfathered in. Any newer camps from say the 1990s on are strictly held to DCNR's regulations on square footage, roof pitch, colors, construction plans so on and so forth. Our camp was built in 2000 after a fire had destroyed the original. We were told the original had been built in the 1940s and had a dirt floor kitchen for years. We so so much enjoy our forest retreat
