The city's file doesn't name contractors, so we can't rank, compare or profile firms here: these pages show what was built, where and when.
Building, trade and post-card permits the DC Department of Buildings issues across the whole District of Columbia. Home occupation permits, elevator shop drawings, civil plans, variances and after-hours work permits are left out. Arlington, Alexandria and the Maryland suburbs run their own permit offices and are not in this file.
