1000 lbs for a 400 sq ft deck actually is doable--imagine 5-10 people on it. You can even test it that way (beware using womenfolk
). Things like a bed, dresser, desk, human bodies, etc add quickly to a 16' yurt to get to 1000 lbs. I mentioned weight because I imagined a big heavy yurt on a balcony 2-3 stories up
Looking at
nyc.gov, your deck should hold 16000 lbs (40 lbs/ft^2) but is only 8 ft wide, if new. With a roof, it's considered another room. Dang--nasty codes.
Actual code: Ch 1 definitions: tent=structure=building. Ch 1, Sec 28 Article 104.4 'Work Exempt from Permit' does not include the usual 'tiny buildings exempt' clause. Didn't check for Accessory building/dwelling/unit loopholes.
Aha! Ch 1, Section 28, Article 111.1-Temporary Structures and Uses. No permit required for a tent <400 sq ft and used for <30 days. Hopefully your deck is rather private & you're on good terms with your neighbors/landlord so they won't complain? You could probably get away with it
Worst case: yurt up 29 days, taken down 1 day, setup again for 29 days--lather, rinse, repeat (monthly chore for occupant). Don't know what the borough comissioner would think...
Traditional yurts are an incredible design solution to scarce building materials, cold winter deserts, and high winds. With waterproof materials, they do rain and snow, too. If you don't accumulate more than 2-3 inches snow, you should be fine; otherwise you should have bagana (crown ring supports)/snow kit upgrade or anticipate a collapse in heavy snowstorms in mid-to-large yurts. A lightweight camping yurt without tiedown/tightening ropes will be useless in wind (easily fixable) and cold in the winter without insulation/proper sealing (fixable)--who knows what it'll do in snow though.
If going lightweight, you might consider
Shelter Systems--modern tents/domes of similar size, much cheaper and lightweight. Also quicker assembly/take down (for snow/storm/inspections). No insulation though
Might be a good way to test the waters of a deck tent/yurt.
