home improvements and repairs, provided they meet certain requirements. (Form B-61 provides information
about the requirements that apply to Owner-Builders makes you aware of your responsibilities and possible
risk you may incur by having a permit issued to an Owner-Builder.) Permits for multi-family projects are only

includes all proposed work such as all structural work, finish work, painting, roofing, electrical,

demands, rights and causes of action of any kind with respect to the building permit application, the
purpose of which is to challenge, attack set aside, void, modify, or annul the approval or denial of the

subrogation and contribution against the Indemnified Parties while acting within the scope of their
duties, from all claims, losses and liabilities arising out of or incident to activities or operations
performed, regardless of any prior, concurrent or subsequent passive negligence by the Indemnified
Parties.
