Termite treatment

Our HOA board discovered 3 of the 147 units have subterranean termites (21 buildings) . These are 7 year old units in 3 buildings in the back of the community. We had a termite inspection and only these units have termites. All units were inspected and my unit did not have termites and is only 3 years old. The builder did a pre-treatment when built. This is a townhome community. They have contracted a pest control company to treat all units. They are drilling holes in the rear concrete patios (Limited Common Area) and around the entire perimeter of the garage inside our townhome. If any flooring was installed in the garage the property management company said we have to remove it.
Our CC&Rs explains HOA maintenance responsibility and pest control or termite control is not included. The cost of treatment is around 25K and approved at a council meeting. While I am thankful the HOA is proactive in treating and paying for the termite treatment, I would like some clarification on there rights inside my home
If my garage is improved and permitted as living space does HOA have right to make me remove improvements without reimbursement. My unit was inspected and does not have termites.

The association members were not asked to vote on the issue. The board motioned and voted on it at a "Council" meeting. I forgot to mention that 2 of the townhomes were owned by current or former board members. My question pertains to the HOA rights to come inside my property and have me remove improvements which will reduce my property value. My townhome is on a concrete slab, was pretreated by the builder and was inspected and contains NO signs of any termite infestation. There are 7 brand new buildings and the units that were infested are 7-8 years old. Our CC&R states homeowners are responsible for and pest control inside the walls.

I don't have an issue with them treating the common area or even the limited common area but they are requesting to come into the deeded area of my home and have me remove improvements without any reimbursement.

A couple thoughts

If the HOA maintains the exterior then preventing termite damage would seem to be part of that maintenance task.

There probably language somewhere in your documents that says you must provide access for necessary maintenance tasks.

Your area and construction appears to be prone to termite infestation. If this occurred in your unit in the future, you would need to provide access for treatment at that time. It might not be a bad idea to swallow hard and deal with this now.
