This is important information that is normally disclosed on the multiple listing information or HOA documents all of which you should have had access.
There are a wide variation for guidelines on pets ranging from, NO pets to pets allowed. Then there are guidelines that fit between these.....like pets allowed but they must conform to a size and/or weight limit. Another common regulation is a limit on the number of pets that are allowed. The strangest pet limitation we have encountered is pets allowed on only one side of the street....hmmmmm
Whether or not it will help depends on the association but writing a letter to the association requesting a variance for their regulation may be worth a try.
Our recommendation is to contact your agent for a clarification of the community guidelines.
