In Connecticut, you can generally build a mother-in-law suite on your property, subject to local zoning regulations and building codes, which vary by municipality. To determine your eligibility and specific requirements, it's crucial to consult with your local zoning and building department. Consider factors such as zoning regulations, size, design, permits, occupancy limits, health and safety codes, utilities, and potential homeowner's association (HOA) restrictions. Consulting local authorities and professionals familiar with local regulations is essential to ensure compliance and a successful project.
