A new interior wall might need a permit, or it might be completely exempt — it depends almost entirely on two things: whether the wall creates a new habitable room, and whether that room (or the wall itself) will have electrical outlets. A simple partition wall in an existing room with no electrical work often requires no permit. A wall that divides a bedroom into two bedrooms, or that encloses a new bathroom, almost always does. The reason: the building code cares about egress (emergency exit), ventilation, electrical safety, and room-use classification. Those are fire and life-safety issues. A wall that changes the footprint of a habitable space, or that carries electrical service, crosses from cosmetic repair into structural and MEP (mechanical, electrical, plumbing) territory. This page walks you through when you need a permit, what you'll file, what it costs, and how to avoid the most common rejection pitfalls. The safe starting point: if you're creating a new room or running new circuits, call your local building department before you start framing. A two-minute conversation can save you months of rework.
When interior walls require a permit
The most common trigger for a new interior wall permit is creating a new habitable room. Per IRC R105, any permit is required when the work affects the layout, occupancy classification, or egress routes of a building. A wall that subdivides a bedroom into two bedrooms changes the occupancy classification (two bedrooms instead of one) and may affect egress — a second bedroom needs its own window or door for emergency exit. A wall that encloses a bathroom needs a permit because bathrooms have specific ventilation, electrical, and fixture requirements (IRC Chapters 27–29). A wall that closes off a hallway or blocks egress definitely needs a permit. The same applies to a wall that creates a new storage room, office, or any other habitable or occupiable space.
The second major trigger is electrical work in the wall. New circuits, outlets, switches, or light fixtures in the wall cavity almost always require a separate electrical subpermit (NEC Article 210 governs branch circuits and outlets). Even if the wall itself is simple and non-structural, the electrical work isn't. This is a trade-specific permit pulled by a licensed electrician in most jurisdictions, though some homeowner-friendly states allow owner-builder electrical permits with inspection. Plan for this as a separate line item from the wall permit.
A third, less obvious trigger is structural support. If the new wall carries load (sits under a floor joist or truss), it's structural and needs a permit with foundation/footing details. Most new interior walls are non-load-bearing — they rest on a single top plate anchored to a rim joist or band board and don't carry roof or floor loads above. But if there's any ambiguity, the building department will ask for a framing plan or engineer's letter. When in doubt, assume structural and budget for a $100–$200 engineer's letter.
Conversely, a simple non-structural partition wall with no electrical work and no new room creation is almost always exempt. A cosmetic half-wall divider in an open loft, a temporary storage enclosure in a garage, a false wall for aesthetic purposes in an existing room — these typically sail through without a permit. The key is that the wall doesn't change the functional footprint or occupancy of the building and doesn't trigger code requirements for the new space.
Most jurisdictions also require permit review if the wall affects fire-rated assemblies. Interior walls adjacent to a garage, for example, may need fire-rating on the garage side (IRC R302.6). A wall that ties into a fire-resistance-rated ceiling, roof, or floor assembly will need documentation that the wall maintains that rating. This usually means a detail drawing showing how the top plate is sealed and fastened.
The decision tree is straightforward: Does the wall create a new room (bedroom, bathroom, office, storage, etc.)? Does it carry load? Does it involve electrical work? Does it affect an existing fire-rated assembly? If yes to any of these, get a permit. If no to all of them, it's likely exempt — but verify with your building department before you buy framing lumber. One phone call beats one permit rejection.
How new interior wall permits vary by state and region
The IRC is the national baseline for building codes, but every state and many cities amend it. Some states have adopted the 2021 or 2024 IRC; others are still on 2015 or 2012. These code editions have small differences in occupancy classification and egress rules, but the permit trigger for a new habitable room is consistent across all of them. Where variation matters most is in how jurisdictions define 'habitable room' and how strictly they enforce permits on small projects. Some jurisdictions require a permit for any wall that changes room count; others exempt walls that don't create new 'habitable' spaces (bedrooms, living areas) and allow bathroom and storage enclosures without a permit if electrical is already in place.
California's Title 24 energy code adds an extra layer: any wall that affects exterior-wall insulation, air sealing, or thermal bridging may trigger plan-review requirements even if the wall is non-structural and interior-only. Florida's wind and hurricane code (Florida Building Code, 8th Edition) requires structural review and impact-rating documentation for any wall that affects roof-to-wall connections or lateral load paths, which almost any new interior wall technically does — so Florida departments tend to require structural permits for nearly all new wall work, even simple partitions. Conversely, some rural or smaller jurisdictions in the Great Plains, Midwest, and South East have very light touch permitting: a new interior wall that doesn't involve electrical and doesn't create a new bedroom may not require a permit at all.
State licensing rules also vary. In California, any electrical work requires a licensed electrician's electrical permit and includes state fees. In owner-builder states like Florida, Arizona, and parts of the Midwest, homeowners can pull electrical permits themselves with inspection. In Massachusetts, New York, and some northeast states, electrical work typically requires a licensed electrician and municipal electrical inspector. Check your state contractor board's website or ask your building department whether the homeowner can pull an electrical subpermit or whether an electrician's license is mandatory. This can shift total cost from $50 (wall permit only) to $300–$500 (wall plus electrical permit plus electrician fees).
Labor and material value reporting also varies. Some jurisdictions use the International Building Code's permit-by-floor-area method (smaller projects = smaller permit fees or over-the-counter processing). Others use contractor's estimated cost of work to calculate fees (typically 1–2% of project valuation). A $2,000 wall-and-electrical project might be $75–$150 in one jurisdiction and $200–$400 in another. Call ahead, get the actual fee schedule, and budget accordingly.
Common scenarios
You want to divide a bedroom into two smaller bedrooms with a new wall
This is the textbook case for a new interior wall permit. You're creating a new habitable room (the second bedroom) and changing the occupancy classification of the house. Both bedrooms need compliant egress — typically a window (IRC R310) with a minimum 5.7 square feet of opening area and a sill no higher than 44 inches. If the existing window doesn't meet this for one of the new bedrooms, you'll need to add another window or door, which itself triggers permit review. The wall itself is likely non-load-bearing (it sits between rim joists or a band board, not under a floor above). File a full building permit with a framing plan, egress details (window location and sizing), and your local building department will review for code compliance, then schedule a rough-framing inspection before you drywall. If you're running electrical outlets in the wall for the new bedroom, also file an electrical subpermit. Typical timeline: 1–2 weeks for plan review, 3–5 days for inspection. Fees: $150–$350 for the wall permit, plus $75–$200 for electrical if required.
You want to add a non-load-bearing partition wall to create a storage closet in an existing room, no electrical work
This is likely exempt if the wall is purely cosmetic and doesn't change the footprint or occupancy of a habitable room. A storage closet added to a bedroom, living room, or garage is a feature, not a new room. It doesn't require separate egress, it's not classified as a new habitable space, and if you're not running electrical, there's no code trigger. Verify with your local building department by describing the location and size, but most will clear you to build without a permit. Even though you don't need a permit, follow standard framing practices: anchor the top plate to the rim joist with 16-inch on-center fasteners, use 2x4 studs on 16-inch centers, and install blocking at 48 inches if the wall is taller than 8 feet (IRC R602.3). If you change your mind and want electrical in the closet later, you'll file an electrical permit at that time.
You want to add a wall to enclose a laundry area or pantry within an existing room
This hinges on whether the laundry or pantry qualifies as a 'habitable room' under your local code. Per the IRC, a laundry or pantry is not classified as a habitable room — they don't require egress or minimum ventilation by themselves. So a simple wall enclosure with no electrical should be permit-exempt, just like the storage closet scenario. However, if you're running electrical for washers, dryers, or task lighting, that electrical work requires a permit. Also, if the wall affects an existing fire-rated assembly (e.g., the laundry is adjacent to a garage or mechanical room that requires fire-rating on the laundry side), you'll need to show that the wall maintains that fire-rating, which may require a permit to review the details. If the space is very small (under 50 square feet) and has no electrical, check with your building department — some jurisdictions grant a blanket exemption for utility enclosures under a certain size. If electrical is involved or the wall is fire-rated, budget for a $75–$200 permit and 1-week review.
You want to add a wall to create a new bathroom in a basement or existing open space
Creating a new bathroom always requires a permit. Bathrooms trigger multiple code sections: IRC Chapter 27 (plumbing fixtures and drain sizing), Chapter 28 (water supply and distribution), IRC R303 (ventilation — bathrooms must have an exhaust fan venting to outside or a window). The wall itself is non-structural in most cases, but the wall must be fire-rated if the bathroom adjoins a garage or is within 3 feet of a furnace or water heater (IRC R302.6, R303.4). You'll file a full building permit with a framing plan, electrical and plumbing layout (showing exhaust duct routing and outlet locations), fixture schedule, and ventilation details. The electrical work (outlets, switches, exhaust fan circuits) requires a separate electrical subpermit. Plumbing (if you're running new lines) requires a plumbing subpermit. If the bathroom is in a basement with below-grade walls, you'll also need grading and drainage review (IRC R405). Timeline: 2–4 weeks for plan review due to the number of code checks. Inspections: rough electrical, rough plumbing, framing (if fire-rated), final electrical, final plumbing, final building. Fees: $200–$500 for building, plus $100–$250 for electrical and plumbing subpermits.
You want to add a non-structural wall in a garage to create a small workshop or storage bay, with one new outlet
The wall itself might be permit-exempt (it's non-structural, it's not creating a habitable room). But the new outlet triggers an electrical permit. A garage outlet carries a 20-amp circuit per NEC 210.52(E) and must have GFCI protection per NEC 210.8. Depending on your jurisdiction, the homeowner can pull the electrical permit and request inspection (owner-builder states), or a licensed electrician must pull it (licensed states). Either way, the electrical work requires a separate permit and inspection. The building department may ask for a simple one-line diagram showing the circuit, outlet location, and GFCI protection. Budget for $50–$100 for the electrical permit and 3–5 days for plan review and inspection. If the garage has other outlets already on circuit, you may only need to verify that the new outlet doesn't overload the circuit (count existing loads, add 180 VA per outlet, ensure total is under 2,400 VA for a 20-amp, 120V circuit per NEC 210.11).
Documents you'll need to file and who can pull the permit
| Document | What it is | Where to get it |
|---|---|---|
| Building Permit Application | The initial application form, typically filled out by the homeowner or contractor. Includes project address, scope of work, estimated cost, and property owner information. Some jurisdictions also ask for a brief narrative describing what the wall will do (e.g., 'divide master bedroom into two bedrooms, add egress window'). | Your local building department website, or in person at the permit counter. Many departments now offer fillable PDFs or online submission portals. |
| Floor Plan with Wall Location | A scaled floor plan (usually at 1/4 inch = 1 foot) showing the existing room layout, the new wall location, dimensions, and how the wall relates to existing doors, windows, and mechanical equipment. If the wall creates a new room, also show egress (window or door location). Drawn on the architectural plans (blueprints) or on graph paper if hand-drawn — either is fine as long as it's clear and dimensioned. | You draw this, or your architect/designer draws it. If you're hiring a contractor, they typically prepare this as part of the estimate. |
| Framing Detail (if structural or fire-rated) | A 1:3 scale section drawing showing how the wall is framed: top plate attachment method (bolts, screws, fasteners), stud spacing, bottom plate detail (nailed or glued), and how the wall ties into adjacent structural elements. If the wall is fire-rated, show firestopping details and caulk location at the top and bottom. This is often a simple sketch annotated with IRC section numbers. | Your contractor or framing crew prepares this, or you can sketch it yourself if you're confident in framing details. Building departments often accept generic details from IRC R602 (Wood-Framed Construction) with a note that the wall will be built per that standard. |
| Electrical Layout (if applicable) | A floor plan showing outlet and switch locations, circuit designation (e.g., '20A branch circuit, Outlet 1, Kitchen'), and the breaker location. If you're adding a new circuit or running a circuit through the wall, also note wire gauge, conduit, and GFCI/AFCI requirements. This is filed separately as part of the electrical subpermit. | Your electrician prepares this if they're pulling the permit. If you're pulling a homeowner electrical permit, you'll sketch this based on NEC requirements (outlet spacing, GFCI zones, etc.). |
| Plumbing Schematic (if bathroom or kitchen) | A simple plan showing fixture locations (toilet, sink, shower, tub), drain and supply line routing, and vent stack location. If you're running new drains or supply lines, include slope diagrams (drains slope 1/4 inch per foot per IRC P3113.1). Filed separately as a plumbing subpermit. | Your plumber prepares this. If you're handling plumbing yourself in an owner-builder state, sketch this per IRC Chapter 27 requirements and include fixture specs. |
| Proof of Ownership | A recent property tax bill, deed, or mortgage statement showing you're the property owner (or permission letter from owner if you're a tenant or contractor). Some departments skip this if you're filing online and they can cross-reference assessor records. | Your county assessor's website or your mortgage servicer. |
Who can pull: In most states, the property owner can pull a building permit for their own home without a contractor's license (owner-builder privilege). A contractor or hired architect can pull it on your behalf with a signed authorization. For electrical work, variation is significant: in owner-builder states (CA, AZ, FL, parts of the Midwest), the homeowner can pull the electrical permit themselves with a state contractor ID number and subject to inspection. In licensed states (NY, MA, NJ, some others), a licensed electrician must pull the electrical permit. Plumbing follows similar rules — check your state contractor board's website or ask your building department directly whether you can pull electrical/plumbing subpermits yourself or whether licensed trades are mandatory. When in doubt, hire the licensed trade — they'll pull the subpermits and handle inspection coordination.
Why permit applications for new interior walls get rejected — and how to fix them
- Scope is vague or incomplete. You've listed 'new wall' but haven't said whether it creates a new room, carries load, or involves electrical. The building department can't approve a vague scope.
Rewrite the scope as a complete sentence: 'Non-load-bearing partition wall to divide master bedroom into two bedrooms; new 24-inch egress window in south bedroom; new 20-amp outlet on east wall for nightstand.' This tells the reviewer exactly what code sections to check. Vague scopes get sent back for clarification, which adds 1–2 weeks to review time. - Framing plan is missing or too simplified. You've drawn a wall on the floor plan, but the reviewer can't tell how it's anchored, whether it's structural, or how it ties into the floor/roof above. They need a section detail.
Add a vertical section (side-view) drawing showing the wall's top and bottom plate connection, stud spacing, and how the top plate is fastened to the existing structure. If the wall is non-structural, label it as such and cite IRC R602.3 (non-load-bearing walls). If you're unsure about the detail, ask your contractor or submit a 'will be built per IRC R602.3' note. Most departments will accept a generic framing detail from the IRC with a local stamp. - Egress details are missing for a new bedroom. You're creating a second bedroom, but the floor plan doesn't show a window or door for emergency exit. Per IRC R310, bedrooms must have a window (5.7 sq ft minimum opening, sill height 44 inches max) or a door to the outside.
Add a window or door to the new bedroom and dimension it on the plan. Show the rough opening size, sill height, and note that it meets IRC R310 requirements. If you're using an existing window, verify it's at least 5.7 square feet of opening area (rough opening minus frame); if not, you'll need to upgrade to a larger window or add a second exit. - Fire-rating requirement not addressed. The wall adjoins a garage or is too close to mechanical equipment, so it needs fire-rating, but the application doesn't mention this or show how it's achieved.
Check the IRC for fire-rating triggers in your jurisdiction (typically IRC R302.6 for garage separation, 3 feet from furnace/WH, etc.). If your wall is affected, either move it further away or show a fire-rated assembly detail (1-hour fire-rated drywall, sealed top plate, etc.). If unsure, ask your building department whether the wall location requires fire-rating before you submit. - Electrical and plumbing subpermits not filed separately. You've applied for a building permit to build the wall, but you also need electrical (for outlets) or plumbing (for a bathroom). The building department won't approve the building permit without evidence that you've filed the trade permits or have a plan to do so.
File trade subpermits concurrently with the building permit. If you're hiring an electrician or plumber, ask them to pull the subpermits on the same day you submit the building permit. If you're doing the work yourself, file the subpermits at the same time or be prepared to provide proof of filing when the building department asks. Some departments allow you to hold the building permit pending the trade permits; others require proof of filing upfront. - Cost estimate is missing or too low. You've listed the wall as a $500 project, but the scope includes new electrical, a window, and drywall — the actual cost is $3,000–$4,000. The building department may reject the low estimate as incomplete or calculate permit fees based on their own estimate, not yours.
Get a contractor's estimate and list the full project cost: materials, labor, and all trades. Be realistic — the building department is estimating cost to calculate permit fees, not to judge your budget. A full bathroom with wall, electrical, and plumbing easily runs $2,000–$5,000+; a simple partition wall with an outlet might be $300–$800. If you're unsure, ask the building department what cost they typically use for your scope and work backward from there. - Code citation or edition is wrong. You've referenced the 2012 IRC, but your jurisdiction adopted the 2021 IRC. The reviewer doesn't recognize the section number or the rule has changed, so they ask for clarification.
Check your jurisdiction's building department website or call to confirm which code edition they use (2024, 2021, 2018, 2015, or older). Cite that edition in your application. If you're unsure about a specific rule, cite the IRC by subject (e.g., 'egress per IRC R310') without a section number — the building department will interpret it per their adopted code. Avoid cherry-picking code editions; use the one your jurisdiction has adopted.
Typical costs for a new interior wall permit
Interior wall permit costs vary widely by jurisdiction and scope. A simple non-structural partition wall with no electrical may be only $50–$100 (or completely exempt). A wall that creates a new room and triggers electrical, plumbing, and fire-rating review can run $300–$500 or more. Most jurisdictions use a tiered fee schedule: either a flat fee based on project type (all interior partition walls = $75) or a percentage of estimated project valuation (1–2% of total labor and materials cost). A few departments use square footage of altered space (new wall creates X square feet of new room, so fee = X × rate per square foot). Call your building department and ask for their fee schedule for 'new interior wall,' 'interior remodel,' or 'room reconfiguration' — the category name varies. Be prepared to provide an estimated cost of work (materials and labor) to calculate the exact fee. Also budget for trade subpermits (electrical, plumbing, HVAC if required) and associated inspections. Electrical subpermits typically run $50–$150; plumbing subpermits $75–$200. If you're hiring contractors to pull these, they'll often bundle the permit fees into their bid. If you're pulling permits yourself, each subpermit is a separate line item.
| Line item | Amount | Notes |
|---|---|---|
| Building permit (simple partition wall, no electrical/plumbing) | $50–$150 | Flat fee in most jurisdictions. Over-the-counter processing in many departments, approved same day or next day. |
| Building permit (wall creating new habitable room: bedroom, bathroom, office) | $150–$350 | Includes plan review. Typical review time 1–2 weeks. May require framing, electrical, and plumbing subpermits. |
| Electrical subpermit (new outlets, switches, circuits) | $75–$200 | Separate from building permit. Required if any electrical work is in the wall. Pulled by licensed electrician in most states; homeowner in some owner-builder states. |
| Plumbing subpermit (new bathroom fixtures, drains, supply lines) | $75–$250 | Required if wall encloses bathroom or kitchen with new fixtures. Includes fixture review and drain sizing check. |
| Structural engineer's letter (if uncertainty about load-bearing) | $100–$250 | Optional in many cases; may be requested by the building department if wall location or framing is ambiguous. Speeds approval. |
| TOTAL (partition wall with new bedroom and electrical outlet) | $300–$700 | Building permit + electrical subpermit + inspections. Does not include contractor labor or materials. |
Common questions
Do I need a permit if I'm just moving an existing interior wall a few feet?
Yes, if the wall defines a room boundary or you're removing and relocating it. Removing a wall (even a non-structural partition) may trigger egress review if it affects how people exit a room. Moving a wall a few feet could change room dimensions below code minimums. File a permit and let the building department assess whether egress, ventilation, or occupancy is affected. If the wall is a simple non-structural partition and the new location doesn't affect egress or room count, you may get an exemption — but get that in writing before you start demo.
What if I'm building a wall that doesn't go all the way to the ceiling?
A partial-height wall (a half-wall or knee wall) usually doesn't require a permit if it's non-structural and cosmetic. However, if the wall is 36 inches or taller and could affect smoke/heat/sound spread in a building (e.g., a wall between units in a multi-family building), you may need permit review to verify it doesn't compromise fire separation or occupancy. If it's in a single-family home and purely decorative (like a low divider in an open kitchen), it's likely exempt — but confirm with your building department. If the wall has electrical outlets, you'll need an electrical subpermit even if the wall is non-load-bearing.
Do I need a permit for a stud wall behind drywall if I'm not creating a new room?
Not typically, if you're just adding insulation or soundproofing inside an existing room (e.g., resilient channels and drywall for sound dampening in a bedroom). However, if the studded wall redefines the room's footprint or affects egress, you may need a permit. The safest approach: describe the exact location and purpose to your building department in a phone call. Is it purely cosmetic (the room is still one room, just with thicker walls)? Probably exempt. Does it enclose a closet or new space? Permit required.
How do I know if a wall is load-bearing?
A wall is load-bearing if it carries the weight of the floor or roof above. In a wood-frame house, load-bearing walls typically sit directly above a foundation wall, a beam, or a post. They're often near the center of the house (carrying floor joists from both sides) or at the perimeter (supporting the rim joist and roof). Non-load-bearing walls sit between joists (atop a rim board or band joist) and don't carry load from above. If you're unsure, hire a contractor or structural engineer to inspect the location ($100–$200 for a simple assessment). If the wall location is ambiguous, the building department will ask for a structural review anyway — so budget for this upfront.
Can I pull a permit for a wall myself, or do I need a contractor?
Most jurisdictions allow property owners to pull their own building permits (owner-builder privilege). You fill out the form, submit the plans, pay the fee, and attend inspections. You don't need a licensed contractor for the permit — only for the actual work if your state requires a licensed framer or carpenter. For electrical and plumbing subpermits, the rules vary: some states allow homeowners to pull them, others require licensed trades. Check your state contractor board's website or call your building department and ask, 'Can a homeowner pull an electrical permit for their own home?' If yes, ask whether you need a contractor ID number. If no, you'll hire a licensed electrician to pull the permit.
How long does plan review typically take for an interior wall permit?
For a simple partition wall with no new room creation and no electrical: 1–2 days. Many departments approve these over-the-counter (same day). For a wall that creates a new room (bedroom, bathroom): 1–2 weeks, depending on the department's backlog and how complete your plans are. For a wall with fire-rating, structural uncertainty, or multiple trade permits: 2–4 weeks. If the department bounces back with requests for clarification, add another week per round-trip. The best way to speed up review: submit complete plans with all code details (egress, framing, electrical layout, fire-rating) the first time. Incomplete or vague submittals get bounced back and add weeks.
What if the building department says my wall needs to be fire-rated, but I don't think it does?
Ask them to cite the specific code section that requires fire-rating and get it in writing. Common triggers: IRC R302.6 (walls between living areas and garages); R303.4 (bathroom/mechanical room fire-separation). If you disagree with the interpretation, you can request a variance or get an engineer's letter supporting a different approach (e.g., moving the wall further away instead of fire-rating it). Most jurisdictions allow alternatives — the code requires the end result (fire separation), not the specific method. If fire-rating is required, expect to use 1-hour-rated drywall, sealed top and bottom plates, and fireblocking; this adds cost but is straightforward to execute.
Do I need separate permits for the wall, electrical work, and plumbing, or one combined permit?
Separate permits, filed concurrently. The building permit covers the wall structure. The electrical subpermit covers circuits, outlets, and switches. The plumbing subpermit covers fixtures and drains. You can submit all three at the same time to your building department, or file the building permit first and the trade subpermits right after. Coordinating timing helps: if all three are under review, you can schedule a combined inspection (framing, rough electrical, rough plumbing on the same day) instead of three separate appointments. Ask your building department whether they offer combined inspections or prefer separate ones.
What happens if I build a wall without a permit and then try to add it to my certificate of occupancy or sell the house?
The building department or a home inspector will discover it during a final inspection, occupancy verification, or sale disclosure. You'll be required to obtain a permit retroactively, submit as-built plans, and pass inspection. If the wall fails inspection (improper framing, wrong egress, electrical hazard), you may be forced to remove or modify it. This is expensive and disruptive — rip-out and rework can cost more than the original work plus a permit fee. You may also face fines and liability issues if someone is injured due to a code violation. The smart move: get a permit upfront. It's $50–$350 and takes 1–4 weeks. Avoiding it costs you months and thousands of dollars later.
Ready to move forward with your interior wall project?
Before you start framing or drywall, contact your local building department and describe your project in concrete terms: the wall location, whether it creates a new room, whether you're adding electrical, and whether it affects existing structural or fire-rated assemblies. A five-minute phone call will give you a definitive answer on whether you need a permit and what documents to prepare. If a permit is required, gather your framing plan, electrical layout (if applicable), and project cost estimate. Submit them in person or online through your building department's portal. If your department offers over-the-counter processing for simple partition walls, you may have approval and a permit in hand the same day. For more complex work (new bedrooms, bathrooms), plan for 1–2 weeks of review. Once you have the permit, schedule inspections as you frame and finish the work — this protects you legally and ensures the wall meets code. If you have specific questions about your jurisdiction's requirements, ask to speak with the plan reviewer or the chief building official. Most departments are happy to clarify before you spend money on a wall that may not pass inspection.
