Permits are not paperwork added after a remodeling plan is finished. They are part of the plan. Whether a kitchen or bathroom project needs approval depends on what is changing, which trades are involved, and which authority has jurisdiction over the property.
This guide gives Montgomery County homeowners a practical starting point. It is general information, not legal advice or a permit determination. Requirements, fees, forms, and review timelines can change. Confirm the current rules for your address and exact scope before work begins.
When Is a Permit Commonly Required?
A permit is more likely when the remodel changes plumbing, electrical wiring, gas service, ventilation, walls, structure, windows, doors, or the number and location of fixtures. Replacing finishes in the same locations may involve fewer approvals, but the exact answer depends on the work and jurisdiction.
Start with the Montgomery County Department of Permitting Services online portal. If the property is inside an incorporated city, confirm whether the city or county administers each part of the work.
Kitchen Projects That May Trigger Permits
- Moving or adding a sink, dishwasher, gas range, or water line
- Adding or changing electrical circuits, receptacles, or hardwired lighting
- Installing or changing gas piping
- Adding or changing mechanical exhaust
- Removing or altering a wall
- Changing a window or exterior door opening
- Making structural changes for an open-concept layout
Painting, replacing hardware, or swapping some finishes may not require the same review. However, a cosmetic-looking project can still include regulated work behind the walls.
Bathroom Projects That May Trigger Permits
- Moving or adding a toilet, shower, tub, or sink
- Changing plumbing drains, supplies, or vents
- Adding electrical circuits, outlets, lighting, or heated flooring
- Installing or rerouting an exhaust fan
- Moving walls or changing the room footprint
- Adding a new bathroom
- Making structural changes or creating a new exterior opening
A vanity replacement in the same position is different from relocating the sink across the room. A tub-to-shower conversion may involve plumbing, waterproofing, electrical, and inspection considerations even when the room size does not change.
Permit Types You May Encounter
Building permit
Often associated with structural work, wall changes, substantial alterations, and work that requires plan review.
Plumbing permit
May apply when fixtures, drains, vents, or water lines are installed, relocated, or materially changed.
Electrical permit
May apply to new circuits, wiring, receptacles, lighting, heated floors, and other electrical work.
Mechanical or gas permit
May apply when ventilation, ductwork, gas piping, or fuel-fired equipment changes.
One renovation can require more than one permit and more than one licensed trade.
A Practical Permit Process
- Define the scope: Mark every fixture, wall, opening, appliance, and building system that will change.
- Confirm jurisdiction: Verify which local authority handles the property.
- Identify required documents: Depending on scope, this may include plans, product information, a contract value, trade details, or structural information.
- Submit before work: Allow time for questions, corrections, and review.
- Post and follow the permit: Keep approved documents available as required.
- Schedule inspections: Rough work is often inspected before walls are closed.
- Complete final approval: Do not treat construction completion as permit completion until required finals are closed.

Start My Remodeling PlanWhat Inspectors May Need to See
The inspection sequence depends on the approved work. Rough inspections commonly occur while framing, piping, wiring, or ducts remain visible. Closing walls too early can lead to reopening completed surfaces. Final inspections may check fixtures, devices, ventilation, life-safety items, and overall compliance with the approved scope.
Your contractor should explain the expected sequence before construction and build inspection time into the schedule.
Who Should Pull the Permit?
The contract should name the responsible party. A contractor handling the permit can reduce homeowner coordination, but the homeowner should still receive the permit number, know which inspections are required, and confirm that the permit closes correctly.
Be cautious if a contractor pressures you to pull permits in your own name solely to avoid contractor requirements or responsibility. Ask why, confirm the legal implications with the local authority, and verify the contractor’s Maryland home-improvement license through the state public query.
What Can Happen If Required Permits Are Skipped?
- A stop-work order
- Fines or added fees
- Delays while plans and inspections are arranged
- Opening completed walls so concealed work can be inspected
- Problems during a future sale or insurance claim
- Responsibility disputes between homeowner and contractor
The cost of doing the process correctly is usually easier to manage than correcting undocumented work later.
How Permits Affect the Schedule
There is no single approval time for every renovation. A simple trade permit and a structural kitchen alteration do not follow identical paths. Application completeness, plan review, revisions, workload, and inspection availability all matter.
Ask the contractor to separate the estimated permit period from material lead times and on-site construction. A promise to start immediately is not valuable if cabinets are not ordered or approvals are unresolved.
Questions to Ask Your Contractor
- Which permits apply to my exact scope?
- Which authority has jurisdiction over this address?
- Who prepares and submits the application?
- Are fees and drawings included in the contract?
- Which inspections are expected?
- Who schedules them and attends them?
- How will corrections affect price and time?
- Will I receive copies of approvals and final inspection records?
Frequently Asked Questions
Do new cabinets require a permit?
Cabinet replacement alone may not require the same approvals as changes to plumbing, electrical systems, gas, walls, or structure. Confirm the complete scope, not just the visible cabinet work.
Does moving a kitchen sink require a permit?
Moving the sink changes plumbing and may involve regulated work. Confirm the requirement with the local authority and a properly licensed contractor.
Does a bathroom tile replacement require a permit?
Finish replacement may be treated differently from changes to plumbing, wiring, ventilation, structure, or the shower assembly. Ask about the entire project.
Can construction begin while the permit is pending?
Do not assume it can. Confirm what, if anything, is allowed with the permitting authority before starting regulated work.
