Dear client,  

The specific legalities and regulations regarding your situation may vary depending on the laws in your jurisdiction, so it's important to consult with a local legal professional for accurate advice. However, I can offer some general suggestions that might be helpful.

Check local building codes and regulations: Research the local building codes and regulations that govern residential properties in your area. Look for any restrictions or guidelines related to the conversion of residential properties into PG accommodations. This information can provide you with an understanding of whether the owner's plans comply with the regulations.

Review the property's deed and zoning regulations: Examine the property's deed and any applicable zoning regulations. These documents may outline the permitted uses of the property and any restrictions that may apply. It is possible that converting the property into a PG accommodation might violate these rules.

Consult a lawyer: Seek advice from a lawyer who specializes in property and real estate law. They will be able to review your specific situation, including any relevant local laws and regulations, and provide you with appropriate guidance.

Discuss concerns with the owner: It may be helpful to have a conversation with the owner about your concerns. Explain your worries regarding the noise, security, and loss of privacy that may arise from converting the property into a PG accommodation. See if you can reach a mutual understanding or come up with alternative solutions that could address your concerns.

Gather support from neighbors: While you mentioned that some neighbors might be hesitant to sign a letter of complaint, it may still be worth trying to gather support. Speak with your neighbors and explain your concerns. If they share similar worries, they might be willing to sign the letter or offer their support in other ways.

Engage with the colony's governing body: If the colony president has asked you to write a letter, it indicates that they are open to addressing the issue. Follow the president's instructions and draft a formal letter outlining your concerns. Submit the letter along with any supporting evidence, such as photographs or recordings of the noise disturbances, if available.

Remember that this advice is general in nature, and it's crucial to consult with a legal professional who can provide guidance based on the specific laws and regulations in your jurisdiction.
