Before you sign an agreement, it would be advisable to read all the rules and accept the rules prior to signing. However, if the rules in place do not suit your lifestyle then you shouldn't sign the contract, but instead look for a different condo. In many locations, you will find that there are some condominiums that don't allow certain pets within the compound or building. If you're pet-friendly the condo won't allow you to live in the building or sign the contract. So, be aware of the rules before settling on an apartment in Singapore.
