It's interesting to note that some residences, like Ken Barlow's, date back to the beginning of the show (and have a history prior to that) while others began their existance only after the construction of the large exterior set in the 1990's, like Gail Platt's.
I'm always amazed at how the writers have maintained this continuity. Most of this info comes from Corrie.net
First off, Coronation Street was constructed in 1902, along with the Rovers Return. The pub was built by the Newton and Ridley Brewery and was named after Lt. Philip Newton who had just returned from the Boer War. Originally, it was called the Rover's Return but Newton had the apostrophe dropped so that it would honour all war veterans, and not just him.
Number 1 Coronation St: Currently owned by Ken Barlow and occupied by Ken, Deirdre, Tracey, and Amy Barlow, along with Deirdre's mother, Blanche Hunt. Ken has lived there as a teenager, on and off as an adult, and now is there as a grandfather.
Number 3 Coronation Street: Owned and occupied by Emily Bishop. Norris Cole is her lodger.
Number 5 Coronation Street: Owned by Weatherfield Council. Occupied by Les, Cilla, and Chesney Battersby-Brown. Kirk Sutherland has recently moved to his parents' place to run the kennels.
Number 7 Coronation Street: Owned by
Number 9 Coronation Street: aka The Rectory. Owned by Jack and Vera Duckworth. Occupied by Jack, Vera, and Tyronne Dobbs, their lodger. On Corrie Classics, the Duckworths are at Number 6, across the street, and the Number 9 is currently occupied by Judy and Gary Mallett.
Number 11 Coronation Street: Currently owned by ???. Was owned by Steve Macdonald and occupied by Eileen Grimshaw and her sons Jason and Todd. Steve sold the house to an unknown buyer in order to finance Karen's Wedding of the Century. The buyer kept the house as a rental property and is currently occupied by Eileen, Jason, his girlfried Violet, and Sean Tully, Eileen's lodger and confidant.
Number 15 Coronation Street: The Corner Shop. Currently owned by Dev Alahan. The shop has been on the street since the First World War. Dev bought the shop, along with six others, from his uncle, Ravi Desai.
There is a house number 13, but nobody is listed as living there. Bad luck maybe?
And now, on to the other side, or the "posh side," as Vera calls it:
Number 2: The Salon. Owned by Audrey Roberts.
Number 2A: Flat above the Salon. Owned by Audrey Roberts, rented by Maria and Candice (I think, a number of the teens have moved in and out so I think they're the current occupants).
Number 4: Owned by Fred Elliot. Occupied by Fred Elliot, Ashley, Claire and Joshua Peacock. Was the site of Maxine Peacock's murder at the hands of Richard Hillman.
Number 6: Was owned by the Harris'. However, Tommy is dead at the hands of Katy and Angela is doing her porridge for obstruction of justice. I assume when he died, the house became exclusively Angela's. I'm not sure how the legalities of that sort of thing would work. She obviously can't make mortgage payments from jail. On the other hand, they moved to the street as part of the witness protection programme so maybe the court bought it in the Harris' name? Anyway, current occupants are Keith Appleyard (Angela's father) and Craig Harris.
On Classic Corrie, the house is occupied by Des Barnes.
Number 8: Owned by Gail Platt. Occupied by Gail, Sarah-Lou, David, and Bethany Platt, as well as Sarah-Lou's boyfriend, Scooter. Gail's ex, Martin lives in the flat above D&S Hardware.
Number 10: The Kabin. Owned and operated by Rita Sullivan. Norris Cole is (currently) employed as a shop assistant. 10A is the flat in the back where Rita lives, for now.
Number 12: Owned by Alec Gilroy. Occupied by Steve MacDonald and until last year, his ex-wife Karen.
Number 16: Websters Auto Centre. Owned by Kevin Webster. Was formerly owned by Mike Baldwin as MVB Motors. The business folded and Kevin and his co-worker Tony Horrocks bought it from the bank. Tony left Weatherfield and left his share of the garage to his mother. Later, it was discovered Tony was murdered by Jez Quigley. I'm not sure if Kevin now owns the garage outright or if Nathalie Horrocks still maintains a co-ownership. Current employees are Tyrone Dobbs and Nathan Harding.
And at the end of the street lays Underworld, owned and operated by Mike Baldwin.
Feel free to fill in any gaps I may have missed.
