The Pennsylvania suburbs are not one housing stock. The Main Line runs to stone colonials and twins with slate origins, steep pitches, dormers and copper valleys. The boroughs, Media, West Chester, Doylestown, Phoenixville, hold dense pre-war rowhomes and twins. Push west and north and it turns into stone farmhouse country and large-lot development from the 1980s onward, out through Chester County and upper Bucks.
Permits here are municipal, never county. Your township or borough codes office issues them under the Pennsylvania Uniform Construction Code, and a borough is often a separate authority from the township wrapped around it. We work out which one owns your address, pull the permit and close it out.
