Summary

No one may encroach on Wauwatosa city land, a right-of-way or an easement, including the strip behind the curb where sidewalks sit, without common council authorization. Municipal Code Section 12.42.010 requires an application to the board of public works and, for structures needing a building permit, a nonrefundable fee before work begins.

No person, firm or corporation shall encroach upon any city land, right-of-way, and/or easement without authorization of the common council. ... Prior to encroaching upon any city land, right-of-way and/or easement, an application shall be made to the board of public works, together with a description of the proposed encroachment. A nonrefundable fee as set out in the fee schedule shall be paid to the city treasurer when applying for an encroachment involving a retaining wall or a structure for which a building permit is required. The board of public works is authorized to waive the encroachment fee when in the judgment of the board unusual or extraordinary circumstances exist which justify such waiver. ... In addition to any other rights the city may have in regard to its land, right-of-way and/or easements, the city may remove any unauthorized encroachment from such land, right-of-way and/or easement and place the cost for such removal as a lien against the abutting property if such encroachment can be reasonably determined to have been caused by such property owner or tenant thereof.

Full Breakdown

42, Encroachments, governs any private use of city-owned land, rights-of-way or easements, which covers the parkway strips and public right-of-way where sidewalks and driveway approaches sit. 010 flatly bars any person, firm or corporation from encroaching on city land, right-of-way or easement without authorization from the common council, tracing to Ordinance O-76-17 of 1976. 020, describing the proposed encroachment. A nonrefundable fee set by the city's fee schedule is due to the city treasurer when the encroachment involves a retaining wall or any structure that itself requires a building permit; the board can waive that fee only where it finds unusual or extraordinary circumstances justify it, a waiver added by Ordinance O-96-1 in 1996.

030 requires the property owner to sign an encroachment agreement, drafted by the city attorney, which still needs final approval from the common council after the board of public works makes its recommendation. 040 requires the city clerk to record that encroachment agreement in the Milwaukee County register of deeds' office, tying the authorization to the land itself rather than to the current owner personally. 050 gives the city the right to remove it and, where the encroachment can reasonably be traced to the property owner or tenant, to place the removal cost as a lien against the abutting property, on top of any other remedy the city has.

Violations & Fines

Encroaching on city land, a right-of-way or an easement without common council authorization under Section 12.42.010 exposes the encroachment to removal. Under Section 12.42.050 the city can take out the unauthorized structure itself and place the cost of removal as a lien against the abutting property whenever the encroachment can reasonably be traced to that property's owner or tenant.

Frequently Asked Questions

Do I need a permit to put a retaining wall in the Wauwatosa right-of-way?
Yes. Section 12.42.020 requires an application to the board of public works and a nonrefundable fee for any encroachment involving a retaining wall or a structure that itself needs a building permit, before the work goes in on city land, a right-of-way or an easement.
Who has to approve an encroachment agreement in Wauwatosa?
The common council gives final approval. Section 12.42.030 requires the property owner to sign an agreement drafted by the city attorney, and the board of public works must make a recommendation before the council signs off.
What happens if I build something in the right-of-way without authorization?
Section 12.42.050 lets the city remove the unauthorized encroachment outright, and if the encroachment can reasonably be traced to the property owner or tenant, the city can place the cost of that removal as a lien against the abutting property.
Can the encroachment fee be waived?
Yes. Section 12.42.020 lets the board of public works waive the nonrefundable encroachment fee, but only where the board finds unusual or extraordinary circumstances justify the waiver; a waiver is not automatic.
