The Short Answer
A full kitchen remodel in Longview requires permits if you're moving walls, relocating plumbing, adding electrical circuits, modifying gas lines, venting a range hood to the exterior, or changing window/door openings. Cosmetic-only work — cabinet and countertop swap, appliance replacement on existing circuits, paint, flooring — does not require a permit.
Longview's Building Department applies Washington State Building Code (currently the 2018 IBC with Washington amendments), which mandates permits for any structural, mechanical, plumbing, or electrical work beyond like-for-like replacement. What sets Longview apart from neighboring Clark County jurisdictions is the city's dual-fuel infrastructure: many older Longview homes have both natural gas and propane service available, and the city's code enforcement on gas-line work is strict — a common rejection point is failure to show gas-line sizing and shut-off valve location on the electrical/mechanical plan. Longview also sits in a mixed climate zone (4C west, 5B east of I-5), meaning frost depth varies from 12 inches near the Cowlitz River to 30+ inches inland; this affects sink-cabinet drainage and under-floor rough-in routing. The city requires a single consolidated building permit that bundles plumbing, electrical, and mechanical (range-hood vent) reviews — not separate tickets — which streamlines approval but means one hold-up delays everything. Plan review typically takes 3-5 weeks; re-submits add 1-2 weeks per round. Lead-paint disclosure and testing are required if the home was built before 1978 (Longview has significant 1960s-70s housing stock).

What happens if you skip the permit (and you needed one)

Longview full kitchen remodel permits — the key details

The Washington State Building Code (2018 IBC + WA amendments) requires a permit whenever you alter the kitchen's structure, mechanical systems, plumbing, electrical, or gas infrastructure. The threshold is deliberately low: moving a single load-bearing wall, relocating a sink (even 2 feet), adding a dedicated circuit for a dishwasher, venting a range hood through an exterior wall, or modifying a gas line all trigger the requirement. IRC Section R602 (Load-Bearing Wall Changes) mandates engineer-stamped calculations if you remove or cut a wall; IRC Section E3702 (Small-Appliance Branch Circuits) requires two independent 20-amp circuits dedicated to counter receptacles, spaced no more than 4 feet apart and protected by GFCI outlets (IRC E3801); IRC Section P2722 (Kitchen Drains) specifies trap-arm length and venting configuration; IRC Section G2406 (Gas Appliance Connections) requires flexible connector supply lines, proper shutoff valves, and pressure-test documentation. Longview's Building Department does not allow 'partial' permits — if you're moving a wall and relocating plumbing in the same remodel, the building, plumbing, and electrical reviews happen under one consolidated permit number, not three separate tickets. This creates accountability but also means delays in any one trade hold up final sign-off.

The city's approach to range-hood venting is a frequent pain point. IRC Section M1502 (Kitchen Ventilation) allows both ducted exhaust and recirculating filters, but Longview's code officer strictly enforces ducting to the exterior — recirculating filters are not accepted as a substitute. The duct termination detail is mandatory on your mechanical plan, including wall thickness, duct diameter (typically 6 or 8 inches), cap type, and insulation R-value. Many homeowners assume they can route a range hood through a soffit or attic; the city requires a dedicated, unobstructed path to daylight on an exterior wall, and the termination cap must face downward with no louvers or dampers that could trap moisture. If your kitchen is on the first floor and you want to terminate on the second-floor exterior wall, you'll need to show penetration details, flashing, and caulking — this often requires additional engineering ($300–$500). Longview Building Department publishes no formal range-hood requirement document, but inspectors consistently enforce ASHRAE 62.2 (ventilation standard), which has been adopted into the WA code.

Longview's location in a mixed-frost-depth zone affects under-floor plumbing routing. West of I-5 (near the Cowlitz River), frost depth is 12 inches; east of I-5, it reaches 30+ inches. If you're relocating drain lines, supply lines, or a gas service in a home with a crawl space, you must either bury pipes below the local frost depth or insulate them (R-13 minimum for supply lines, R-5 for drains in unheated spaces). A common rejection: homeowners submit a plumbing plan showing a new sink in a peninsula island without detailing how the trap and vent will route — underslab homes make this especially tricky. Longview's Building Department expects a detailed section view showing trap depth, vent routing (typically up through the cabinet to the roof or wall), and anti-siphon safeguards. If you're adding a dishwasher and relocating the main sink, the plumber must show high-drain connections (no garbage disposal or under-counter filtration can siphon water back into the dishwasher per IRC P2722.2).

Electrical work in Longview kitchens triggers two recurring code violations. First, the two small-appliance branch circuits (20-amp, dedicated to counter receptacles) must be shown on the electrical plan with wire gauge (typically 12 AWG), circuit number, and breaker location — many homeowners or unlicensed contractors assume this is optional or can be added later, and it's the #1 rejection reason. Second, GFCI protection is required on all counter receptacles, and the outlet spacing must not exceed 4 feet measured along the countertop (IRC E3801). This means a 10-foot galley kitchen needs at least three outlets; an island or peninsula adds another. Longview's inspectors check this during rough-in inspection before drywall, so if you skip GFCI installation or mark the plan wrong, you'll fail inspection and delay the project 1-2 weeks for a re-pull and re-inspect. The city does not allow 'GFCI breakers at the panel' as a workaround for counter outlets; individual GFCI outlets or GFCI strips are mandatory.

The permit fee for a full kitchen remodel in Longview is typically $300–$1,500, calculated as 1-1.5% of the project valuation. The city defines valuation as materials plus labor, and you'll estimate this on the permit application (for a $30,000 remodel, expect $300–$450 in permit fees alone). Plan review takes 3-5 weeks; if the city returns comments, re-submission adds another 1-2 weeks. Once permitted, you'll schedule four separate inspections: rough plumbing (before drywall, showing trap/vent routing and drain sizing), rough electrical (showing all new circuits, outlet boxes, and GFCI locations), framing (if walls were moved or opened), and final (all trades complete, inspection of finish work). The entire timeline from application to final occupancy can stretch 8-12 weeks if you encounter one round of re-submits. Longview does not offer over-the-counter plan review or same-day permits; all kitchen remodels go through full review. If your home was built before 1978, you must also obtain a lead-paint disclosure and, if renovation disturbs more than a certain square footage (typically 6 square feet of interior components), arrange lead-safe work practices under EPA RRP (Renovation, Repair, Painting) Rule — violation fines start at $16,000 per violation.

Three Longview kitchen remodel (full) scenarios

Scenario A
Cabinets, countertops, and appliances only — 1970s ranch in Mint Valley
You're replacing 30-year-old cabinetry with new stock cabinets from a big-box store, installing new Formica countertops, and swapping the old electric range and refrigerator for new models of the same size. The sink stays in place, the dishwasher stays in place, and you're not touching walls, plumbing, gas lines, or electrical circuits. This is purely cosmetic work — no permit required. You can hire a handyman, friend, or contractor without licensing concerns. However, if the old appliances had gas connections and you need the gas line capped or tested, that's a change to the gas system, and you'll need a permit. Similarly, if the new appliances are wider or deeper and you need to move drain or supply lines even slightly, a permit is triggered. Bottom line: no permit if you're swapping like-for-like with no system changes. Cost: $8,000–$15,000 materials + labor, zero permit fees.
No permit required (cosmetic only) | No inspections | Appliance connections by appliance dealer | Contractor licensing not required | Total project $8,000–$15,000 | Zero permit fees
Scenario B
Moving sink 4 feet, adding island, new range hood with exterior duct — Riverside neighborhood
You're gutting a 1965 Colonial in the Riverside neighborhood (west of I-5, frost depth 12 inches). The kitchen is small, so you're moving the sink from the north wall to an island peninsula in the center, running new supply and drain lines under the floor (buried 12 inches deep, wrapped in insulation). You're also installing a 30-inch range hood with a 6-inch duct that penetrates the south exterior wall, and upgrading the electrical panel by two new 20-amp circuits for counter receptacles plus a 240V circuit for an induction cooktop. Load-bearing walls stay in place. This requires a full building permit bundled with plumbing and electrical permits. The plumber must submit a plan showing the new trap-arm configuration, vent routing (likely up through the island cabinet), and supply-line sizing (probably 3/4-inch copper). The electrician must show the two 20-amp GFCI circuits, the induction cooktop circuit (10 AWG, 240V, 40-amp breaker), and all outlet locations and spacing. The mechanical plan must show the range-hood duct diameter, wall penetration with flashing detail, and exterior cap location. Longview's plan-review process will likely flag the range-hood termination detail (make sure the cap is a simple downward-facing design, no damper) and may ask for an engineer's sign-off on the island structure if it's cantilevered or non-standard. Inspection sequence: rough plumbing (trap/vent and supply routing visible before drywall), rough electrical (all circuits and boxes in place), framing inspection (the island support), and final. Timeline: 5-7 weeks from application to permit issuance, then another 2-4 weeks of construction with inspections interspersed. Lead-paint disclosure required (pre-1978 home). Permit fee: $400–$800 based on $25,000–$35,000 project valuation. Total project cost: $30,000–$50,000 including permits, inspections, and contractor labor.
Permit required | Building + Plumbing + Electrical (consolidated) | Plan review 3-5 weeks | Four inspections (rough plumbing, rough electrical, framing, final) | Range-hood duct and cap detail mandatory | Load-bearing wall assessment not required | Permit fees $400–$800 | Total project $30,000–$50,000
Scenario C
Load-bearing wall removal, gas range conversion, full electrification — Mint Valley (east side, frost depth 30+)
You own a 1980s ranch on the east side of Longview (frost depth 30+ inches). The kitchen is closed off by a load-bearing wall that you want to remove to open the space to the dining room. You're also converting from an electric range to a new gas range (requiring a gas-line run from the meter), and you're adding all-new 240V induction cooktop and built-in wall oven on a separate circuit (because you want both options during transition). This is a complex permit scenario that requires engineering. The load-bearing wall removal demands an engineer-stamped structural design letter specifying a steel or engineered-wood beam size, header support posts, and foundation requirements (IRC R602.3 requires this for removal of any wall supporting more than 200 sq ft of roof/upper-floor load). Longview's Building Department will not issue a permit without the engineer's letter; expect $800–$1,500 for the engineer's stamp. The plumber must show the new gas supply line routing from the meter to the range location, including shutoff valve location, flexible connector type, and pressure-test requirements (per IRC G2406). The electrician must show the 240V branch circuit for the gas range ignition (usually 20-amp, 12 AWG), the 240V 50-amp induction cooktop circuit (6 AWG), and the 240V 50-amp wall oven circuit (6 AWG), plus the two 20-amp GFCI circuits for counter receptacles (per IRC E3702). The east-side frost depth (30+ inches) means any new supply or drain lines must be buried below frost or insulated heavily; the plumbing plan must call this out explicitly. The rough plumbing inspection will check the gas-line routing and shutoff-valve accessibility. The rough electrical inspection will verify all new circuits, breaker sizing, and GFCI outlet placement. A structural inspection will verify the beam installation and posts before drywall closure. This is a 8-12 week project from permit application to final occupancy. Longview's code officer will likely require a re-submittal on the first round (missing beam-connection details or GFCI spacing), adding 2 weeks. Permit fee: $900–$1,500 based on $40,000–$60,000 project valuation, plus $800–$1,500 engineer fee (not included in permit fee). Lead-paint testing and RRP certification mandatory if home built pre-1978 (likely here). Total project cost: $50,000–$85,000 including engineer, permits, and contractor.
Permit required | Structural engineer letter mandatory (beam design) | Building + Plumbing + Electrical + Mechanical (consolidated permit) | Plan review 4-6 weeks (likely 1 re-submittal) | Five inspections (rough plumbing, rough electrical, structural, framing, final) | Gas-line sizing and shutoff-valve detail required | Frost-depth burial (30+ inches east of I-5) affects drain/supply routing | Permit fees $900–$1,500 | Engineer fee $800–$1,500 | Total project $50,000–$85,000

Range-hood venting and why Longview inspectors are strict about ducting to exterior

Longview's Building Department enforces range-hood ducting to the exterior wall (not recirculating filters) based on ASHRAE 62.2 ventilation standard adoption in the Washington State Building Code. The requirement is that moisture, cooking odors, and combustion byproducts must be exhausted directly outside, not recirculated back into the kitchen air. Many homeowners assume a recirculating range hood is acceptable because it filters grease and odor, but filters do not remove moisture — and moisture in a sealed kitchen leads to mold, condensation damage, and indoor air quality problems. The city's code officer will reject a permit application that shows a recirculating hood without explaining why a ducted exhaust hood is infeasible.

The ducted path must be direct and unobstructed: minimum 6-inch diameter (8-inch preferred for high-CFM hoods over 800 CFM), insulated with at least 1-inch fiberglass wrap if the duct passes through an unconditioned space (attic, crawl space), and terminating in a 45-degree downward-facing cap on the exterior wall. Dampers and louvers inside the duct are problematic because they trap condensation; Longview's inspectors disallow spring-loaded dampers in the duct itself, though a bird-cap damper at the exterior termination is acceptable. If your kitchen is an interior room with no direct path to an exterior wall, you must reroute the duct vertically through the roof or an upper-floor wall — this often requires penetrating roofing and adds cost ($500–$1,200 for flashing and roof patching).

The plan-review hold-up: most rejections occur because the applicant submits a plan showing a range hood with a vague note like 'exhaust to exterior' but no duct diameter, cap type, or wall-penetration detail. Longview requires a detailed mechanical plan section or detail view showing the duct path, any elbows, insulation wrap, wall thickness, cap design, and clearance from property lines or other structures. If the exterior wall is a fiber-cement board or stucco finish, the flashing detail must be explicit — vinyl siding requires a different flashing approach than brick. The cost of proper ducting and flashing typically adds $800–$1,500 to the project; trying to avoid it by using a recirculating hood costs time in permit rejections and eventually the inspection failure.

GFCI outlets, two small-appliance circuits, and why spacing matters in Longview kitchens

IRC Section E3801 (GFCI Protection) and E3702 (Small-Appliance Branch Circuits) are the two most frequently violated electrical codes in Longview kitchen remodels. The requirement is non-negotiable: all kitchen counter receptacles must be protected by ground-fault circuit interrupters (GFCIs), and at least two 20-amp dedicated circuits must serve counter-top outlets. These two circuits cannot be shared with other loads (refrigerator, dishwasher, microwave on separate circuits). The spacing rule is 4 feet maximum, measured horizontally along the countertop from the center of one outlet to the center of the next. This means a 12-foot galley kitchen requires a minimum of three counter outlets; an island or peninsula doubles the count.

Longview's inspectors check outlet spacing and GFCI protection during the rough electrical inspection, before drywall closes the walls. If the plan shows incorrect spacing or missing GFCIs, the inspection fails, and the contractor must schedule a re-inspection after correcting the work — delays of 5-7 days are common. Many homeowners or unlicensed electricians assume that a single GFCI breaker at the panel protects all circuits on that breaker, or that strategic outlet placement can skip GFCI installation. Neither is true: IRC E3801 requires individual GFCI outlets (or GFCI power strips for flexibility) on every counter receptacle, or a GFCI breaker that protects that specific circuit. If you use a GFCI breaker, downstream standard outlets receive GFCI protection but do not display a GFCI test button — this can confuse future owners and electricians. Longview's code officer recommends individual GFCI outlets for clarity.

The two small-appliance circuits rule often surprises homeowners because it seems redundant — why two circuits instead of one larger one? The reasoning: kitchen counters are high-risk areas for shock (wet hands, metal appliances, water), and a short circuit could trip both circuits at once if they're on the same breaker, leaving the kitchen dead. Two independent 20-amp circuits, each with its own breaker, ensure that a short on one circuit doesn't black out the entire counter. The circuits must be labeled clearly on the electrical plan and the breaker panel directory, and they cannot feed any outlets outside the kitchen counter area. Plugging in a coffee maker and a toaster on one outlet is fine; plugging a refrigerator into the second kitchen circuit is a violation.

Common questions

Do I need a permit if I'm just replacing kitchen appliances?

No — replacing appliances of the same type and size on existing circuits and gas/water connections does not require a permit. However, if the new appliance has different electrical or gas requirements (e.g., upgrading to a 240V induction cooktop or converting from electric to gas), you'll need permits. Similarly, if the new appliance is larger and requires relocating plumbing or gas lines, a permit is required.

What if I hire a contractor — do they need a license in Longview?

Yes, any electrical work in Longview requires a licensed electrician (Washington State electrician license); any plumbing work requires a licensed plumber; any gas-line work requires a licensed gas fitter. The general contractor who oversees the project does not need a specific license, but all trade-specific work must be done by licensed professionals. Longview's Building Department verifies contractor licenses during plan review.

How long does the kitchen remodel permit process take in Longview?

Plan review typically takes 3–5 weeks from submission. If the city returns comments or requests re-submittal (common for range-hood duct details or GFCI spacing), add 1–2 weeks per round. Once the permit is approved, construction and inspections usually take 4–8 weeks, depending on project scope. A typical full remodel from application to final occupancy spans 8–12 weeks or longer if you encounter delays.

Can I do the electrical or plumbing work myself if I own the home?

Washington State law allows owner-occupied homeowners to do certain electrical and plumbing work on their own property without a license, but Longview's Building Department still requires a permit and inspections. You must be the property owner (not a tenant or investor), and the work must pass final inspection. Most homeowners hire licensed professionals to ensure code compliance and avoid inspection failures — the cost of a licensed electrician or plumber is typically less than the cost of re-work if you fail inspection.

What is the permit fee for a kitchen remodel in Longview?

Permit fees are calculated as 1–1.5% of the project valuation (materials plus labor). A $30,000 remodel typically costs $300–$450 in permit fees; a $50,000 remodel costs $500–$750. You'll estimate the valuation on the permit application. Longview's Building Department may adjust the fee if your estimate seems unreasonably low or high. There are no additional inspection fees; inspections are included in the permit cost.

Do I need a lead-paint disclosure if my kitchen remodel disturbs old paint?

Yes, if your home was built before 1978 (very common in Longview), a lead-paint disclosure is required before work begins. If the remodel disturbs more than a certain square footage of lead-painted surfaces (typically 6 square feet of interior components like cabinets or trim), you must follow EPA RRP (Renovation, Repair, Painting) Rule protocols: hire an RRP-certified contractor, use lead-safe work practices, and document compliance. Violations can result in fines starting at $16,000 per violation.

What happens if I discover an unpermitted kitchen remodel when I buy a house in Longview?

You must disclose the unpermitted work on any future sale (Longview's Property Condition Disclosure form requires this). Many lenders will not refinance a home with known unpermitted electrical or plumbing work; this can block you from better interest rates. Buyers often demand price reductions of $10,000–$30,000 or require the work to be removed or legalized. Legalizing unpermitted work requires submitting plans, paying double permit fees, and passing all inspections — often more expensive than doing it right the first time.

Can I get a permit for a kitchen remodel if I'm just renting the house?

No, tenant-initiated kitchen remodels do not qualify for permits in Longview without explicit written consent from the property owner. The permit application requires the property owner's signature and phone number. If you're a landlord, you can obtain a permit; if you're a tenant, you must coordinate with the owner or hire a contractor who arranges the permit with the owner's approval.

What if I remove a load-bearing wall in my kitchen remodel?

Removing a load-bearing wall requires an engineer-stamped structural design letter specifying a beam size, header posts, and foundation support. Longview's Building Department will not issue a permit without this letter. The engineer fee is typically $800–$1,500. A structural inspection will verify the beam installation before drywall closes the opening. Removing a non-load-bearing wall (purely cosmetic) does not require engineering but still requires a permit if you're opening the wall to the kitchen area.
