First, a bit of on-topic discussion for the OP: I'd examine your lease to say what it says about tobacco and vapor products - I'm pretty sure there's nothing about vapor, even in a "house rules" addendum that may or may not be part of your standard lease. Could you fight it? Sure - but your landlord could probably argue that since vapor products are considered "tobacco products" under federal law (thanks, FDA!) the same rules apply.
If you win, maybe you get to vape until your lease renews again, at which point your landlord will update the house rules to specifically address vaping, raise your rent to the point you'll be forced to move, or just flat-out kick you out if your locality doesn't have a "just cause" clause for terminating tenancy.
Me? I'd just close the blinds, keep a fan going to circulate air, and not hotbox my apartment with vapor - who's going to know? Make sure you're using glass cleaner on your windows regularly and cleaning your walls every 6 months or so if you're not doing that already - despite what's been said here PG and VG are NOT water, and there is a (much milder than smoke) residue that will affect the interior of your property if you make no attempt whatsoever to clean.
You've never heard of public housing, low rent housing, or subsidized rent housing? If I read correctly, it is a new mandate to include public housing with the notion that non-smokers would be getting 2nd hand smoke from the apartments and children living in those building would be affected as well.
As well, smoking causes damage to the properties. Rather than just washing down the walls, smoking units require washing with a special cleaner (we used T.S.P), then sealant, primer, 2 coats of paint to cover tobacco smoke stains. Now aside from all the other hype pro vs con on vaping, everything in vape juice is water soluble, so from a property owners point of view, would just require a quick wipe with warm soapy water.
I suspect the latter has more to do with no smoking in apartments than the 2nd hand smoke. Money talks. The no smoking rule would save tax payers a lot of money, since public housing units usually get repainted every 3 to 5 years, and soap and 1 coat of paint is far cheaper than repairing smoke damage.
I've heard of public housing, though we don't have it here in San Diego. I do operate several properties under Section 8, which is subsidized rent. While I don't have any properties in the handful of local cities with specific smoking laws, I specify no smoking indoors and have no problem with vaping, though none of my Section 8 tenants are vapers.
I use TSP on every wall I'm going to paint, whether or not a unit had indoor smokers (for several years now, none of mine have). I paint every unit where a tenant has been for more than two years, or if I've turned it over twice in two years.
Still, I'm pretty sure Obama didn't invent public housing, low rent housing, or subsidized rent housing. As a matter of fact, my family was renting to Section 8 tenants before he was even elected, so I'm thoroughly convinced this scourge of providing housing to people with low income isn't solely his administration's responsibility.
HUD Housing (Housing Urban Development)
Yeah, HUD has been around since 1965, it turns out.
