Summary
No building can be erected, structurally altered, or relocated in an unincorporated Waukesha County town without a town building permit, and the town cannot issue that permit until the county zoning administrator issues a zoning permit first.
(1) Required: No Building shall be erected, structurally altered, or relocated until a building permit has been issued by the building inspector, certifying that such Building, as proposed, would be in compliance with the provisions of this Ordinance and with the building code of the town. (2) Application for: An application for a building permit shall be made to the proper Town in which the proposed Building is to be located. (3) Issuance: No building permit shall be issued by the Town, until a zoning permit has been issued by the county zoning administrator.
Full Breakdown
02 of the Waukesha County Basic Zoning Ordinance sets the sequence every builder in the county's towns of Delafield, Genesee, Merton, Mukwonago, Oconomowoc, Ottawa, Vernon, and Waukesha must follow. " That covers new construction, structural alterations, and relocations alike; routine repairs that do not touch the structure fall outside this trigger. Subsection (2) directs the application to "the proper Town in which the proposed Building is to be located," since the town, not the county, issues the building permit itself. " That reverses the order a builder might expect.
02(1) as zoning administrator, has to be in hand first, and only then will the town's own building inspector issue the town's building permit. 03(2) layers on the zoning and occupancy permit application itself, which must be filed in triplicate with a site map, floor elevation data, septic and well locations, and a fee payable to the Waukesha County Park and Planning Commission before or at the same time as the building permit application.
Violations & Fines
Erecting, structurally altering, or relocating a building without the town building permit, or obtaining that permit before the county zoning permit issues, violates Section 3.02 and exposes the owner to the Basic Zoning Ordinance's enforcement remedies, including a stop-work order and citation prosecuted by the county.
