Permit Requirements

Garage permit in Johnson City, TN

It depends — some garage work in Johnson City needs a permit, some doesn't.

A one-story detached accessory structure not exceeding 200 sq ft is exempt from the state building permit (IRC R105.2). However, the city's zoning compliance permit is required for any structure exceeding 100 sq ft or costing more than $100 (Sec. 16.3.1). An attached garage or a detached garage over 200 sq ft requires a building permit in addition to the zoning compliance permit.

How to pull the permit

  1. Put together a site plan showing where the work goes, with dimensions.
  2. Apply through the Johnson City building department.
  3. Pay the permit fee when the permit is issued. Work done before that isn't covered.
  4. Book each inspection listed on the permit as the job reaches that stage.

If you skip it

Doing work without the required permit violates the code. Each violation is a misdemeanor, and every day it continues counts as a separate offense (Sec. 16.6).

Questions people ask

My garage is right at the limit. Does that count?

The exemption has to fit exactly — if the code says a size or height, being at or under it keeps you exempt, and going a single inch over doesn't. When you're close to the line, measure before you buy materials, and call the department if the number is borderline.

I already built it without a permit. What now?

Johnson City can issue a stop-work order and require you to apply after the fact, sometimes with an extra fee. Work that was covered up may have to be opened for inspection. Full walkthrough here.

Does unpermitted work cause problems when selling the house?

Often, yes. A buyer's inspector or the title company may flag it, and lenders can balk at financing a home with open or missing permits. What to do about it.
