The document discusses when and why a reserve study for a community association should be updated. It notes that a reserve study is useful for around 5 years, and should be updated when the condition of building components changes, or the financial status of the association changes significantly. The type of reserve study needed depends on how long it has been since the last study and the extent of any changes. Level I studies provide the most comprehensive new data, while Level II and III focus only on changes. Keeping the reserve study and funding plan up to date helps the association better plan its long-term maintenance and replacement costs.
