Summary
Jefferson County requires a building permit for most construction, alteration, or repair work beyond minor upkeep. The Building Contractor Licensing policy draws the line: cosmetic fixes like painting or drywall patching don't need one, but structural, wiring, piping, or egress changes do.
3. Building Contractor / Contractor: A person who for compensation directs, supervises, or undertakes any work for which a County building permit is required under the Building Code... 7. Repair or Maintenance Work does not include the cutting away of any wall, partition or portion thereof; the removal or cutting of any structural beam or load bearing support; the removal or change of any required means of egress, or rearrangement of parts of a structure affecting the egress requirements; the addition to, alteration of, replacement or relocation of any standpipe, water supply, sewer, drainage, drain leader, gas, soil, waste, vent or similar piping, electrical wiring, or mechanical or other work affecting public health or safety; emergency equipment replacement and repairs for which any required building permit is applied for within the next business day; or any other work requiring a County building permit.
Full Breakdown
Jefferson County's Building Contractor Licensing policy (Part 3, Ch. 8, Sec. ' The policy then draws the permit line through its definition of 'Repair or Maintenance Work,' the category of minor jobs that need neither a contractor license nor a permit: interior decorating, minor exterior maintenance like painting or masonry repair, replacing lamps, connecting portable electrical equipment to existing outlets, minor gas-appliance parts, clearing pipe stoppages, and swapping a water closet without moving pipes or valves. ' A property owner acting as their own contractor on their own home can pull permits without a county contractor license, but only on one residential dwelling in any 24-month period; pulling permits on two or more homes in that window makes the owner a 'Contractor' who must get licensed. The Building Safety Division's Building Official administers permits and licenses under the codes the BCC adopted in Part 3, Ch. 8, Sec. 4.
Violations & Fines
Failing to obtain a required building permit, or ignoring other Building Code requirements, is a licensing violation the Building Official can act on: assessing a fine equal to the license fee, issuing a warning, stopping or suspending work on the project, refusing a certificate of occupancy or final inspection, or revoking the permit or the contractor's license. The contractor or permit holder can appeal any of those decisions to the Board of Review within 14 calendar days of the notice (17 if mailed).
