not sure how recent a development this is, since I haven't been down that way in a few months, but
this project of 258 condos at the corner of Third St and 23rd, and reaching back to Tennessee St, has fencing up and looks like a little demolition has taken place (behind fencing, not visible in pics).
the corner of Third and 23rd:
looking more north up Third to give a little context:
looking west down 23rd:
the 'back' of the site - looking north up Tennessee. all four buildings on the right are to be demolished

at 23rd is where all signs of housing and 'neighborhood' peter out as you move south down Third (you're definitely in sometimes-no-sidewalks territory here), so this project has always seemed like a 'flag-planter' to me, sort of shoring up one of the current boundaries of Dogpatch. (hopefully in future it will be 25th St, then Cesar Chavez, that will feel like the edge). as this is also on the T streetcar line and walking distance from the Caltrain 22nd St stop, I am feeling positive about this one
