The Fairfax County Building Official has the authority to issue a modification to a building code provision provided the proposed change meets the original code's spirit and functional intent. Consider applying for a code modification if:

• Your project's design or construction does not meet the letter of the building code, but you feel it complies with its intent.
• A code provision from an edition of the code that Virginia has yet to adopt better addresses your design or construction.
• You have an alternate design, unknown method or new material that is not addressed in the code.

Each modification is unique to a specific project and cannot be construed as a countywide or statewide code interpretation. A code modification is not a variance or a relaxation of a requirement; the Building Official does not have the authority to waive provisions of the code.
 

This information is the most common for how to obtain the necessary approval for your project and is not representative of all the conditions you may encounter.

 

WHO CAN APPLY?

The administrative provisions of the Virginia Uniform Statewide Building Code permit the owner of the property or the owner’s agent to apply for a code modification.  The owner’s agent may include an architect, an engineer, a general contractor, or somebody else whom the owner may designate.

Review Process

The Building Official and the Code Modification Review Committee will evaluate the technical merits of the proposed code modification. You will be notified in writing of the final ruling which will be an approval, denial or a conditional approval. If you are not satisfied with the decision of the Building Official, you can request a local appeal.
