“Breaking and Entering” achievement is completed by breaking into the following 7 locations in Abah’s Landing town in Hew’s Bane zone:
The numbered locations are:
- Sailor’s Rest
- The Serpent and the Senche’s Private Storeroom
- Jamadin’s House
- Velmont Mansion
- Silver-Claw’s Office
- Lady Balina’s Mansion

The achievement doesn’t require you to steal anything at these locations, only to enter them. You can leave immediately. Sometimes you will be witnessed while trespassing, so make sure you’re prepared for bounties.
Most locations have multiple entry points. Additionally keep in mind that Silver-Claw’s Office is located in the south end of the restricted Warehouse District.
Breaking and Entering achievement is part of the Thieves Guild DLC. Upon completion it rewards you with 5 achievement points.
