planning house addition and used architect/friend. Plans include exterior elevations, roof pitch, joist sizing and spacing, wall and roof construction. Interior has electrical locations, plumbing and vent locations, window sizes/egress, etc etc, several contractors(design/build firms) have told me our plans are insufficient to be permitted. Same architect same detail plans approved, permitted and built for friend. Question is do we need plumbing schematic, electrical, schematic for permitting? I would think that electric and plumbing contractors know their thing and wouldn't need these. Se
The level of detail and specific plans required will vary from jurisdiction to jurisdiction. In my area, specific plumbing and electrical plans are not required for building permits. In those regards, the simple location of electric outlets and ceiling or wall mounted lighting fixtures for electric, and the simple location of sinks, toilets, exterior faucets, etc., are all that is required. That's usually something provided by the architect...on his plans. Best thing to do is call your local authorities and ask. But understand that many times, when contractors talk about things like this, they speak from experience dealing with those same local authorities.
