When do you need a permit?
The rule of thumb: if the work changes structure, plumbing, gas, electrical circuits, or how a space is used, it needs a permit. If you're only swapping finishes in the same layout, it usually doesn't. Typical cases:
| Project | Permit typically required? |
|---|---|
| Painting, flooring, cabinet swap in the same layout | No |
| Kitchen or bath remodel that moves plumbing, gas, or circuits | Yes — alteration + trade permits |
| Finishing a basement (new rooms, wiring, wet bar, bath) | Yes — and egress rules apply to new bedrooms |
| Removing or altering a wall | Yes if structural; drawings must show it either way |
| Home addition or sunroom | Yes — full package with plan review |
| Deck (attached, or above a low height off grade) | Yes in most cases |
| Water heater, panel upgrade, new circuit | Yes — standalone trade permit |
Edge cases exist — the county's own checklists are the final word, and we confirm scope before filing on every project.
The 7 steps of a Fairfax County permit
Scope & drawings
Decide exactly what moves and what stays. The permit package needs floor plans showing existing vs. proposed — clean drawings are the single biggest factor in a fast review. We produce these in-house.
Application through the county portal
Fairfax County processes residential permits online (its PLUS portal): application, drawings, and contractor information are submitted electronically.
Plan review
County reviewers check the drawings against building code. Small trade permits can be issued quickly; alteration packages take longer (see timelines below). Reviewers may issue comments — corrections are made and resubmitted.
Permit issuance & fees
Once the review passes, fees are paid (the county publishes its fee schedule; fees scale with the scope of work) and the permit is issued — for example an ALTR (residential alteration) with linked trade permits like PLBR (plumbing) or electrical.
Rough-in inspections
Framing, plumbing, and electrical are inspected before the walls close. Scheduling these at the right moments keeps the job moving — miss the window and the crew waits.
Final inspection
When the work is complete, the county inspects the finished project against the approved drawings. Pass = the permit is closed out and the work is officially on record.
Records for resale
Closed permits become part of your home's county record — clean paperwork your future buyer's agent and appraiser can verify. Keep copies with your project documents.
Realistic timelines
| Permit type | Typical wait from submission |
|---|---|
| Standalone trade permit (water heater, circuit) | Often within days |
| Alteration package with plan review (kitchen, basement) | A few weeks, depending on county workload and drawing quality |
| Addition / structural package | Longer — plan for it in the project schedule |
These are planning figures, not promises — the county's queue moves around. On our projects the permit wait runs in parallel with material ordering, so it rarely adds net time.
Why the GC should pull the permit
Whoever pulls the permit owns the outcome: drawings, review comments, inspection scheduling, and any rework if something doesn't pass. When your licensed general contractor pulls it, all of that is on us — the county talks to us, the inspectors meet us on site, and failed-inspection fixes are our cost, not yours. An owner permit for contractor-performed work shifts that responsibility onto you; treat that request as a red flag.
This is one piece of the larger case for using a licensed GC — insurance, one accountable contract, code-compliant work — covered on our general contracting page.
Permit FAQ
Do I need a permit to finish my basement in Fairfax County?
Yes. Finishing a basement means new walls, electrical circuits, and usually plumbing — all permit work. Adding a bedroom down there also triggers egress (escape window) requirements, and a wet bar or bathroom adds a plumbing permit. It is one of the most common projects we pull permits for.
What happens if I remodel without a permit?
The county can require you to open up finished walls for inspection, redo non-compliant work, and pay penalty fees. Unpermitted work also surfaces at resale: buyers' inspectors and appraisers flag it, and it can hold up or kill a sale. Retroactive (after-the-fact) permits are possible but slower and more expensive than doing it right the first time.
How long does a Fairfax County permit take?
Standalone trade permits (a water heater swap, a new circuit) are often issued within days. A residential alteration package with plan review — a kitchen with moved plumbing, a finished basement — typically takes a few weeks from submission to issuance, depending on county workload and how clean the drawings are. Build that wait into your project schedule.
Who should pull the permit — me or my contractor?
The party who pulls the permit is the party responsible for the work passing inspection. When your licensed general contractor pulls it, the drawings, corrections, inspection scheduling, and any rework are their problem, not yours. Be cautious of any contractor who asks you to pull an owner permit for work they are performing.
