Compliance certification. No development shall be undertaken without certification by the Inspector of Buildings that such action is in compliance with the then-applicable Zoning Bylaw, or without review by him regarding whether all necessary permits have been received from those governmental agencies from which approval is required by federal, state, or local law. "Development," for these purposes, shall mean erecting, moving, substantially altering a building, sign, or other structure or constructing a driveway. Issuance of a building permit or certificate of use and occupancy, where required under the Commonwealth of Massachusetts State Building Code, may serve as such certification.

Zoning review. Materials submitted in application for such certification shall, upon receipt, be reviewed and forwarded by the Inspector of Buildings to the Select Board, which within 14 days of receipt by it shall determine whether or not the proposal is in compliance with all bylaws and is otherwise eligible to proceed and shall so notify the Inspector of Buildings.

Enforcement. The Select Board shall take all such action as may be necessary to secure full compliance with the provisions of this bylaw, permits issued thereunder and variances granted under this bylaw or applicable statutes.

Penalties.

Other laws. Where the application of this bylaw imposes greater restrictions than those imposed by any other regulations, permits, restrictions, easements, covenants or agreements, the provisions of this bylaw shall control.

Conformance. Construction or operations under a building or special permit shall conform to any subsequent amendment of this bylaw unless the use or construction is commenced within a period of six months after the issuance of the permit and, in cases involving construction, unless such construction is continued through to completion as continuously and expeditiously as is reasonable.

Preexisting nonconforming uses and structures.

Nonconforming lots ("The 1973 amendment"). This section shall not prohibit the erection of a single-family residence on a lot or parcel of land located within the residential zone of the Town of Bolton as set forth in the Base Map if said lot or parcel does not meet the minimum requirements of this amendment; provided, however, that, prior to the effective date in 1958 of the original bylaw, the lot or parcel of land was in single or joint ownership by a deed and/or a plan recorded in the Worcester District Registry of Deeds or that the lot or parcel of land was in single or joint ownership by deed recorded in the Worcester District Registry or a plan recorded in the same registry between the effective date in 1958 of the original bylaw and the effective date of 1973 amendment of this section, and that the plan or plans, as recorded, bear the proper approvals of the Planning Board of the Town of Bolton where required by law; and said deed or plans otherwise conform to the bylaws existent between the effective date in 1958 of the original bylaw and the effective date of the 1973 amendment, for use as a single-family residential building lot.
