Can I add square footage to an existing Keys home?

Short Answer

Adding square footage to an existing Keys home may require permits and in some cases a ROGO allocation, depending on the scope of the addition. Monroe County has specific regulations governing expansions that property owners should understand before starting work.

Adding square footage to an existing Keys home is possible but requires careful planning. If you stay within the existing footprint and foundation, you can usually proceed with standard permits. Expanding beyond the original CO may trigger additional ROGO requirements.
