Who may prepare a reserve study depends on your state and your governing documents: Colorado, for example, accepts an internally conducted study. California requires one at least every three years. Florida requires a structural integrity reserve study for buildings of three or more habitable stories.
You can use this tool without one, working from contractor quotes or your own estimates. A reserve study isn’t a quote for work; current bids override the study’s estimates, so where you have a current bid, plan around it.
