Philip,
Declarant control means that the builder/developer has enough votes to make the decisions, appoint people to the Board, change the governing documents, etc. even if every homeowner voted against it.
Typically, the governing documents are written to provide 1 vote per lot/unit for each homeowner and 10 or more votes per lot/unit owned by the declarat. This ensures that the builder/developer has control of the Association until all of the unimproved lots are sold.
The Property Owners' Association Act, applicable to non-condominium developments, does not provide for a specific time frame for the transfer of control. It only specifies that certain things must happen "once the majority of the members of the board of directors other than the declarant are owners of improved lots in the association and the declarant no longer holds a majority of the votes in the association . . ." Therefore, this is when declarant control would end for non condominiums.
If your development is a condominium, then the
VA Condominium Act has more conditions for declarant control.
Basically, the membership is at the mercy of the declarant until control is transferred to the membership. One way to minimize a declarants impact is to become involved as much as possible in the running of the Association as soon as possible. This can be as little as attending meetings and asking questions to volunteering to serve on committees or as an officer.
I know that this likely isn't what you were hoping to hear but I hope it helps,
