Do I need a permit to remodel a bathroom in Virginia?

Often yes, but not always. A like-for-like cosmetic refresh usually needs no permit, while a remodel that moves a wall, a fixture or a drain, or changes the wiring, does. The Virginia Uniform Statewide Building Code sets the rule, and your local building department applies it, so confirm with them before work starts.

When a permit is required

Section 108.1 of the code says a permit must be obtained before the commencement of work that includes "the removal or addition of any wall, partition, or portion thereof", a "water supply and distribution system, sanitary drainage system, or vent system", or "electric wiring".^[1] In plain terms, a bathroom remodel needs a permit when it:

• takes out or adds a wall or part of one
• moves, adds or changes supply lines, drains or vents
• adds or changes wiring, such as new circuits for a heated floor or fan
• changes mechanical systems, such as a new exhaust duct

Prince William County's guide says the same in its own words, listing "Removing or altering any structural (support) members and any work involving alterations to the house plumbing, electrical, or heating and air conditioning (mechanical) systems".^[2]

What does not need one

The code's list of exemptions includes ordinary repairs such as:^[1]

• Replacement of plumbing fixtures without alteration of the water supply and distribution systems, sanitary drainage systems, or vent systems
• Installation or replacement of floor finishes
• Installation or replacement of cabinetry or trim
• Application of paint or wallpaper

So swapping a toilet, vanity or tub in the same spot with the same connections, re-tiling a floor or repainting does not require a permit under the state code. Prince William County lists the same kind of exemption: "Replacing existing plumbing fixtures (water closets, tubs, sinks, garbage disposals, etc.) where no alteration to the supply or drain/waste/vent systems are involved".^[2]

The exemption has limits. The code says it shall not be construed to exempt such activities from other applicable requirements of the code,^[1] and it also allows for other repair work deemed by the building official to be minor and ordinary.^[1] Moving a toilet a foot to the left is not a like-for-like swap, because the drain moves. When in doubt, call the building department and describe the job.

Asbestos and lead in older bathrooms

Two older-house rules sit alongside the permit. The code lists the removal or disturbing of any asbestos containing materials during the construction or demolition of a building or structure among the activities that need a permit.^[1] EPA says you can't tell whether a material contains asbestos simply by looking at it,^[3] and it suggests having a trained and accredited asbestos professional inspect first if you are planning to remodel.^[3] Lead is a separate federal rule: anyone paid to perform work that disturbs painted surfaces in homes built before 1978 must be certified and their employees trained in lead-safe work practices.^[4]

Who gets the permit

The permit should be the contractor's job and written into the contract. Virginia's Board for Contractors says the contractor should apply for and obtain any necessary building permits, that this should be spelled out in your contract, and that otherwise you may be held legally responsible for failure to obtain any required permits.^[5] It also says all permit applications should match the work as written into your contract.^[5] Do not let a contractor start without a copy of the issued permit.

A permit brings inspections. The code's minimum inspections include "Inspection of electrical, mechanical and plumbing materials, equipment, and systems prior to concealment" and a "Final inspection".^[6] Do not close the walls or make the last payment until the inspections you need have passed.

Fees

Fees vary by locality. In Montgomery County, when we checked on October 26, 2026, residential alterations, renovations and repairs were $0.22 per sq. ft. with a minimum $45 fee, with plumbing and electrical trade permits at $0.03 per sq.ft. with a minimum $45 each.^[7] See how much a bathroom remodel costs in Virginia for what else sets the budget.

When to call a licensed pro

Bathroom work that needs a permit, especially plumbing and wiring, is best left to a licensed contractor and licensed trades, and your building department can tell you what it requires of whoever pulls the permit. Under the Code of Virginia, the Board for Contractors must require a master tradesman licence as a condition of licensing electrical, plumbing and HVAC contractors.^[8] Check the licence before you sign, and read what happens during a bathroom remodel to see where the inspections fall.
