						 Don't have time to read it, but has this really helped with lowering the COL for residents, are prices down?  | 
							
						
 I want more affordable housing for people at both low income and at middle income levels. Some people DO think that more private high end development will filter down, step by step, to even low income levels. Some people think that the number of intervening steps is too great and the effects too indirect and too slow. I am not absolutely certain which is correct (and part of the issue here is that we assume all new private development is high rises on a limited number of parcels and ignore what can be done with ADUs, with multiplexes as Minneapolis is doing, etc) , but for a variety of reasons I think its worthwhile to address low income housing more directly. Partly via density bonuses to developers in exchange for adding committed affordable housing. Partly by making it a condition of private development on govt owned land (not a trivial amount of the new development in the region) And partly with govt subsidies - as you may know DC, Arlington, Alexandria, and I think MoCo all spend govt funds on committed AH. DC spends more - in part because DC has so much more private development and so more tax revenue - another reason private development is good. Also I don't think new subsidized housing has to be concentrated in low income parts. Govts will do that because land is cheaper and sometimes opposition is lower. But its a matter of political will.  | 
							
						
 Its slowed rent increases - given inflation its probably been an inflation adjusted decrease in rent. One of the odder things about these discussions, if supply makes rents lower than they would otherwise have been, people say its not worth doing because it doesn't actually make the city "cheap" by whatever definition they are using.  | 
							
						
 +1 And a lot of new housing stock is small apartments (300-400 sq ft studios), shitty construction, and insane prices. It's not sustainable, IMO.  |

 I agree that limiting supply is not sustainable.  | 
							
						
 It's highly dependent on the area, there isn't much of the lowering of prices happening in older buildings in already desirable areas, because there is always more demand from people to live there for other reasons, better amenities, more decent schools, safer, more police presence, better transit, closer commute, etc. It's not only about shiny new towers that attracts people, especially families with kids we are talking about. If rents fall down in 30 year old building, for example, guess what happens? Then people from less desirable area who were forced there, or would otherwise move there change their minds and move back. Your assumption is that people want newer or larger, but some only would live in specific areas or only desire a certain type of housing, like TH or SFH, especially families, many of whom are not from overseas or NYC and do want lower density for raising a family. It's not one rule applies to all. When neighborhood becomes desirable, then prices rise all over the board and it happens to new or up and coming areas as well.  | 
							
						
 Then who is going to pay to make more supply of family size affordable homes? If developers are building this housing, then that's what's profitable, so someone else has to subsidize the alternative or force them to do otherwise.  | 
							
						
 +2 I always chuckle when people tell me it's better for the environment when they essentially waste energy 24/7. Lobbies are on with lights 24/7. Elevators for a 5 floor condo building. Etc. That and they are crappily just thrown up so quickly with the worst construction, throw in a fresh paint job and some laminate floors, and it's "luxury" for a cheap price of $3500 a month!  | 
							
						
 It's not going to help people who want to live in Dupont/Kalorama for the price of Anacostia or Lyon Village for the price of Mt.Vernon. Lots of posters are people who want yuppie areas or sprawling new homes with best schools inside beltway burbs, but cannot pay, not those who are impoverished trying to just put a roof over their kid's heads and not be shot. It's like those who want to drive a Tesla for the price of Honda Civic, so they wonder and speculate when law will change and luxuries will go cheap. Here is the news, living in posh established desirable parts of any city is a luxury, even if it's an older crappy building, buying a tear down in a prime suburban area with short commute and building a brand new home is a luxury. It's not all because of some malicious political zoning interests, it's how it's always been, there were always expensive parts of DC, people bitched they could not afford, even when most of it was unlivable, and they didn't precipitously dropped in price just because new areas got gentrified or new apartments got built.  | 
							
						
  | 
							
						
 That's precisely what the landlords and companies owning old buildings are doing. They are not dropping prices, they freshen up and they keep renting. Demand doesn't seem to die just because there are newer condos going up. These new condos are more expensive. And new condos going in other areas are not the competition when people want to or need to live in specific areas for work or school or commute or just because they like it better.  | 
							
						
 You know that you can probably power all the lights in that lobby for the better part of a week with the energy in one gallon of gas, right? Also, modern elevators are counterbalanced and so they don't really use as much energy as you might think. I'm not trying to justify every technique of modern building construction, but your claim that large buildings are inefficient is silly. The transportation energy reductions from density and the efficiency gains from shared walls trump pretty much anything you can do to a modern single-family home to make it more efficient.  | 
						
 I chuckle when NIMBYs think that the energy for elevators is a big deal. One of the advantages of biking is you get to understand the topography of the region better. Folks commuting even to the inner suburbs are going far more than 5 flights - and they are doing so in their heavy, inefficient SUVs, not an electric elevator with counterweights.  | 
							
						
 You realize some of those homeowners can easily ride a bike, metro in, and just as energy efficient, right? No one needs a giant SUV if you own a home...  |
