Exceptional Hopkinton development opportunity adjacent to Upton State Forest and located in one of the best school districts in Massachusetts. Preliminary review suggests the property may accommodate multiple subdivision concepts in the 10–12 lot range, depending entirely on engineering, septic testing, and all required approvals. Recent variance reform, statewide 1-acre septic standards, and updated NFPA road guidance may offer added flexibility for future planning. Buyer to perform all due diligence. Existing single-family home has a passing Title V. Land sold as-is.
