It shall be unlawful for any person, as defined in this Code to use and obstruct for building, construction, demolition or razing purposes any street, alley, or sidewalk, or part thereof, without first securing a permit from the director of public works, pay the fee therefor, and giving bond/proof of insurance, provided:
1. No permit shall authorize occupancy of any street or sidewalk space, part thereof, other than immediately in front of, or any alley space immediately behind the lot or lots upon which any building or structure is in process of demolition, razing, erection, or other construction is to be done, and in relation to which such permit is issued, unless consented to in writing by the abutting property owner or owners.
2. During progress of any such operations a sidewalk not less than four feet in width shall be at all times kept open, and protected for the purpose of passage in front of each lot or lots and within the space permitted for occupancy.
3. Such sidewalk shall be protected by a tight board fence at least four feet in height, and when deemed necessary and required in the permit by the director of public works, by a tight board fence of such additional height and an adequate tight board roof.
4. Nothing herein shall be construed to prohibit the maintenance of necessary driveways and gates for the delivery or removal of material across such sidewalks to or from the building, construction, demolition or razing site, provided, a watchman is stationed at the sidewalk to warn and protect the public.
B. No permit, as provided above, shall be required for any roll off box owned and provided by a collector licensed pursuant to Chapter 17, Article II of the City Code. All other provisions of Chapter 32, Article VII, relating to use of public right-of-way shall apply to any roll off box which is used upon and obstructs any street, alley or sidewalk or part thereof.
