Unpermitted Addition Permit

Legalize unpermitted room additions — as-built structural certification, correction plans, and full legalization.

The Challenge

An unpermitted room addition is a serious code issue: it lacks engineered foundations, load-path verification, and often electrical/plumbing inspection. Code enforcement can require legalization or removal, and it blocks resale.

How QuiPermit Helps

QuiPermit engineers the as-built documentation and corrections needed to legalize your unpermitted addition, then works with the building department to bring it into compliance.

The Process

1) As-built assessment of the addition. 2) Sealed structural certification and correction plans. 3) Electrical/plumbing inspection coordination. 4) Submit and resolve to legalize.

What's Typically Required
