Most construction work done within the City limits requires a permit and the corresponding required inspections. All work should be permitted through the Planning and Development Department. All commercial projects must have approval from the Gwinnett County Fire Marshal prior to submitting for approval from the City of Duluth. The stamped/approved plans must be submitted to the City. Plans must also be submitted on disc. 

Mechanical permits (electrical, plumbing, roofing, HVAC) are required as stand alone permits when they are the only work being performed.  An affidavit is required when a building permit has already been issued and this work is being performed as a subcontractor.

Many citizens contact our Department inquiring about when a residential building permit is required. The “rule of thumb” is that a building permit is required if you are modifying or adding to an existing structure.

If you have any questions please contact Carol Hill or Bill Aiken.
