After-the-Fact Permit

Legalize unpermitted construction — after-the-fact permits for work already built without approval. We engineer the as-built documentation your building department needs to approve existing construction.

The Challenge

Unpermitted work is one of the most stressful permitting situations a property owner can face. Whether you inherited unpermitted construction when you bought the property, or work was done without permits, code enforcement can require you to legalize it — which often means opening walls, exposing foundations, and engineering as-built documentation that proves the existing construction meets current code. Most owners don't know where to start and risk penalties, removal orders, or uninsurable property.

How QuiPermit Helps

QuiPermit specializes in after-the-fact permits. Our licensed engineers assess the as-built condition, prepare the documentation your building department requires to approve existing construction, and handle structural certification, correction plans where needed, and the full legalization submission. We coordinate any required inspections and work with the building department to bring your property into compliance with minimal disruption.

The Process

1) As-built assessment — we evaluate the existing construction and what documentation is required. 2) Engineering and documentation — sealed as-built plans, structural certification, and any correction drawings needed for non-compliant elements. 3) Submission — we submit the after-the-fact permit application and coordinate required inspections. 4) Compliance — we resolve any corrections and secure final approval, legalizing the construction.

What's Typically Required

After-the-fact permits typically require: as-built floor plans and elevations, sealed structural engineering certification of existing construction, foundation documentation (which may require selective exposure), electrical/plumbing/mechanical inspection and certification, and correction plans for any elements that don't meet code.

Typical Cost

After-the-fact permits vary widely depending on the scope of unpermitted work and what inspections/exposure are required. Call for a free assessment and quote.

Typical Timeline

After-the-fact permits take longer than new construction because of as-built investigation and required inspections — typically 8–16 weeks depending on scope and jurisdiction.
