Condo docs and estoppels are 2 different things and separate charges apply to each. Each can be ordered individually depending on the circumstances. For instance, a mortgage company may require an estoppel for re-mortgaging purposes and not require condo docs.
Different property managers and boards have different fees for each but a typical charge for an estoppel is $150.00. Fees for condo docs can vary wildly. One self-managed condominium board I dealt with in the past charged $500. Typically the charge will be around $100. However, the new regulations coming into effect January 2020 set the maximum charge for condo docs at $30 for a rush request (within 3 days) and $10 otherwise. The estoppel fee maximum is set at $100.
