3 Georgia jurisdictions we cover publish a fee figure for this work. Each line is quoted from that office's own schedule and linked to its citation. The figures are not comparable to one another: some are flat minimums, some a percentage of job value, some charged per fixture, so what you pay depends on which schedule applies and on your job's valuation.
