It's an interesting predicament.  
The "densify"  movement wants to use the same rules for all neighbourhoods.  Which seems fair but it can have very different impacts on neighbourhoods.

My parents live in an old working class neighbourhood.  Our city has allowed infill development of duplexes, triplexes and low rise condos.  In almost every case, these developments improved the area and property values for everyone.  That's because the new buildings replaced derelict properties that were basically a blight.

However, in other more prosperous neighbourhoods, densification has made the areas look a little less leafy, roomy and lovely.  The new projects replaced homes that already had charm, good square footage and could have been restored.  Essentially, the neighbourhoods were already as improved as they could be and any zoning changes are actually making things worse there.
