How to buffer the raster according the certain value of the cell?

Please, see the attached image that shows my question

I need to get a raster that represent a buffer of 500 m from the built up area (which have the cell value number 3).

If the same problem is in vector, I use the buffer command then erase command.
What are the equivalent commands for raster?
