Four months ago in late November 2012, I posted a comprehensive overview of the residential development boom taking place in Downtown Denver. Today I offer a major update to that effort. As before, I am confining the projects included to those that are new construction multifamily residential (rental or for-sale) of ten units or more and located within a 1.5-mile radius of a geographic central point in Downtown (17th and Arapahoe).

Here’s the updated map. Click/zoom on the image below to view it in a new browser window, or click here to download a high-resolution PDF version.

Next, the revised table (click to view at full size):

So what has changed since November 2012? Here’s a quick analysis:

Four projects moved from “Under Construction” to “Completed,” giving us eight projects totaling 1,284 units that have been completed since the start of 2012.

There are now 29 multifamily residential projects under construction in the Downtown area totaling 4,254 units. This is nine more projects under construction than in November, but it’s really 13 more considering four of the “Under Construction” projects in November have since moved to the “Completed” column. Eight of these additional 13 projects under construction moved over from the “Proposed” column, and five are new projects not included in the table in November that are already under construction.

Only four projects have joined the “Proposed” list since November, and with the eight projects that moved over to “Under Construction,” the total number of proposed units has dropped by nearly half to 1,858. Of those, I’m guessing projects totaling maybe 600 units are good bets to get under construction within the next few months. All together, there are 283 more units (regardless of status) in our March 2013 table than in November 2012. This represents a relatively small increase in the number of newly proposed multifamily residential units over the past four months, which is probably a good thing for now.

Assuming for the moment that all of the projects currently under construction are completed, that about 600 of the units in the “Proposed” column get underway within the next few months, and that no new projects are proposed for the rest of the year, then by the end of 2014, a time frame of three years (2012, 2013 and 2014), we will have added approximately 6,700 residential units within a 1.5-mile radius of the center of Downtown Denver.
