Repairs and Alteration to Existing Buildings

1. You are not required to update existing buildings to current code requirements if: (a) the building and systems were lawfully in existence when the local jurisdiction adopted the code, and if (b) the building and systems are safe as determined by the building official. There are exceptions to this general rule. See smoke alarms.

2. Apply current code requirements when adding to or altering a building and its systems. This means that if you perform work requiring a permit, the permitted work must comply with current code. You are not required to update the existing work to current code requirements. This provision applies regardless of whether or not you actually obtain a permit.
