The Short Answer
A full kitchen remodel in Concord requires permits if you move walls, relocate plumbing, add electrical circuits, modify gas lines, or cut exterior openings for range-hood venting. Cosmetic-only work (cabinet swap, countertops, appliance replacement) is exempt.
Concord's Building Department enforces the 2015 International Building Code with New Hampshire State amendments, and a kitchen remodel crosses the permit line the moment any structural, plumbing, electrical, or gas work happens. Unlike some nearby towns that bundle kitchen permits into a single omnibus fee, Concord requires three separate permits — building, plumbing, and electrical — each with its own plan-review cycle and inspection. This means your timeline stretches: a typical full kitchen takes 4–6 weeks for all three departments to clear plans, then another 2–3 weeks of inspections (rough plumbing, rough electrical, framing/structural, drywall, final). Concord's frost depth is 48 inches and the soil is glacial granite, which matters if you're moving the sink location and need to relocate drain lines — the building inspector will check that trap arms slope correctly (1/4 inch per foot minimum per IRC P2722) and that vent stacks clear the roof per code. New Hampshire has no state-specific kitchen exemptions, so Concord applies the IRC directly: if any wall is load-bearing and you're removing it, you must submit an engineer's letter or beam-sizing calcs; if you're adding a range hood with exterior ducting, you must show the duct termination detail on the electrical plan; if you're relocating the sink or dishwasher, you must show the new trap and vent routing on the plumbing plan. The key Concord-specific detail: the city's permit portal is online, but plan review is sequential (building first, then plumbing and electrical in parallel), so submitting incomplete or vague plans delays the whole sequence.

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

Concord kitchen remodel permits — the key details

The starting point: Concord's Building Department (part of the Planning and Permitting Division) uses the 2015 IBC with New Hampshire amendments, and the single biggest rule is that any structural change — including a load-bearing wall removal — requires a permit and an engineer's letter. The IRC R602.3 defines a load-bearing wall as one that supports roof or floor loads; in a one-story ranch, almost every wall perpendicular to the rafters is load-bearing. If you're opening up the kitchen to the dining room by removing the wall between them, you must hire a structural engineer ($400–$1,200) to size a beam and submit that calcs letter with your building permit application. Concord's building inspector will not sign off on the rough framing inspection without it. The three-permit requirement means you'll pay three separate application fees: building ($150–$300), plumbing ($150–$250), and electrical ($150–$250), totaling $450–$800 before any plan review. The kitchen also triggers electrical work that many homeowners overlook: per IRC E3702.1, kitchens require two small-appliance branch circuits (SABC) — 20-amp circuits dedicated to countertop receptacles — and every countertop outlet must be GFCI-protected and spaced no more than 48 inches apart. If your electrician isn't showing those two circuits on the electrical plan, the plan-review engineer will kick it back.

Plumbing is the second complexity. If you're moving the sink, dishwasher, or garbage disposal, the drain line must slope at 1/4 inch per foot minimum toward the main stack, and the vent must rise unobstructed to the roof (per IRC P2722.2 and P3103). Concord soil is glacial granite with a 48-inch frost depth, so if your kitchen is on a slab, the inspector will check that any new drain penetrations are sloped correctly and trapped properly. The plumbing plan must show the old and new trap locations, the vent routing, and how the new piping connects to the existing main stack. If you're adding a dishwasher and there isn't one now, that's a new fixture requiring both a new drain branch and a new 1/2-inch hot-water line, and the inspector will verify the connection at the plan-review stage. Gas lines fall into the same category: if you're moving a gas range or adding a new gas appliance, the plumbing permit also covers gas, and you must show the new gas line routing, the shutoff valve location, and compliance with IRC G2406 (gas appliance connections). A gas line running through an exterior wall in zone 6A must be insulated to prevent condensation.

Range-hood venting is a trap many homeowners miss. If you're installing a range hood that vents to the exterior (not recirculating), the duct must be shown on BOTH the electrical plan (as an appliance) and the building plan (as a roof or wall penetration). The duct must be sealed where it penetrates the exterior wall, and in zone 6A, you need a backdraft damper or motorized damper to prevent cold air from infiltrating when the hood is off. The building code IRC M1502.1 requires that the duct termination cap is at least 1 foot above the highest point of the roof within 10 feet, or at least 12 inches from any window or door. Concord inspectors will look at this during the final inspection, and if the duct is undersized (most kitchens need a 6-inch duct for a 400-CFM hood), the inspector will flag it as inadequate.

The permit timeline and inspection sequence in Concord is strictly: submit all three permit applications (building, plumbing, electrical) at the same time. Building reviews first and may approve or kick back within 5–7 business days. Plumbing and electrical review in parallel once building clears; that's another 5–7 days. Once all plans are approved, you can start work. Inspections happen in order: rough plumbing (before walls close), rough electrical (before walls close), framing/structural (after walls are up, before drywall), drywall (after drywall is hung), and final (all work complete). Each inspection must be scheduled 24 hours in advance through the online portal. If the inspector fails any rough inspection, you cannot proceed until the deficiency is fixed and the inspector re-approves. A failed rough electrical or plumbing inspection can add 2–3 weeks to your timeline.

One more critical detail: if your home was built before 1978, Concord requires a lead-paint disclosure signed by you and the contractor before any renovation work begins, per the federal EPA RRP Rule. The contractor must be RRP-certified and must use containment and wet-wiping to minimize dust. Failure to do this correctly can result in fines of $100–$500 per day and is a significant liability issue. The Building Department does not enforce the RRP Rule directly, but if an inspector sees evidence of lead-paint disturbance without containment, they can issue a notice of violation. Many Concord contractors build the RRP compliance ($500–$1,500) into the bid, so confirm that your contractor is RRP-certified and that the scope includes containment and clearance testing before you begin.

Three Concord kitchen remodel (full) scenarios

Scenario A
Cosmetic kitchen swap — new cabinets, countertops, flooring, same appliances on existing circuits — West Side ranch
You're keeping the sink in the same location, replacing the old appliances with new ones (refrigerator, microwave, dishwasher) on the existing circuits, installing new cabinets and granite counters, and new vinyl flooring. This is 100% cosmetic and does not require a permit. The refrigerator, microwave, and dishwasher can plug into the existing countertop receptacles — you're not adding any new circuits, moving any plumbing lines, or changing gas connections. Concord's Building Department considers this a cosmetic alteration and explicitly exempts it from the permit requirement. The only catch: if your new cabinets require any new electrical outlet, that's an additional circuit, which triggers the permit. But in this scenario, you're using what exists. You do not need to apply for a building, plumbing, or electrical permit. You do not need inspections. You can hire any contractor (licensed or not) and the work is entirely your responsibility. Cost: $0 in permit fees. Timeline: none — you can start immediately. Inspection: none. The risk: if you hire an unlicensed electrician to move an outlet or run a new circuit without a permit, and later there's an electrical fire, your insurance may deny the claim.
No permit required | Cosmetic-only work | New appliances on existing circuits | Flooring + cabinets + counters | $0 permit fees | Start immediately
Scenario B
Full kitchen with wall relocation — opening kitchen to dining room by removing one wall, relocating sink, new gas range, new range-hood venting — Concord downtown historic district
You're removing the load-bearing wall between the kitchen and dining room, moving the sink to the island, adding a gas range (replacing an electric one), and installing a range hood with exterior ducting through the roof. This triggers all three permits plus structural engineering. First, you must hire a structural engineer to size a beam for the wall removal ($500–$1,200) and submit the engineer's letter and calcs with the building permit. The building permit application includes the engineer's letter, a floor plan showing the old and new wall locations, and details of the beam support (columns, footings, connections). Plumbing permit includes the sink relocation (new supply lines, new trap and vent, connection to the main stack), and because you're moving the sink to a new location, the plumbing inspector will verify the trap slope and vent clearance. Electrical permit includes the range-hood wiring (20-amp dedicated circuit from the panel), the new gas range connection (if it has an electric ignition, a 20-amp circuit is required), and verification that the countertop SABC circuits are GFCI-protected. Gas line work (adding a gas line to the new range location) is covered under the plumbing permit (gas section). Plan review takes 3–4 weeks because the building permit is reviewed first (engineer's letter and beam details), then plumbing and electrical in parallel. Inspections: framing (after the wall is removed and the beam is installed), rough plumbing (sink trap and vent), rough electrical (range-hood circuit and countertop circuits), drywall (after walls are closed), and final. Timeline: 6–8 weeks total from permit application to final inspection. If the home was built before 1978, you must also do the lead-paint RRP work (containment and clearance testing), which adds $1,000–$2,000. This is located in the downtown historic district, so you may also need a Historic Preservation Board approval before removing any wall (verify with Planning Department). Permit fees: building $250, plumbing $200, electrical $200, total $650. Engineering: $600–$1,200. RRP (if pre-1978): $1,000–$2,000. Total project cost: $15,000–$40,000+ depending on contractor and scope.
All three permits required | Structural engineer letter required ($600–$1,200) | Load-bearing wall removal | Sink relocation (trap + vent detail) | Gas line to new range | Range-hood exterior venting (roof penetration) | RRP lead-paint compliance if pre-1978 | 4–6 week plan review | 5 inspection stages | Historic district approval may be required | Permit fees: $650 | Total professional costs: $2,250–$3,450
Scenario C
Kitchen with plumbing and electrical upgrades — same-location sink, new dishwasher, two new small-appliance circuits, new range-hood venting, no walls moved — North End colonial
You're keeping the kitchen footprint the same but adding a dishwasher (new plumbing fixture requiring a new drain and 1/2-inch hot-water line), adding two dedicated 20-amp small-appliance branch circuits (SABC) for countertop outlets, and installing a range hood with a duct venting through the side wall. This triggers building, plumbing, and electrical permits, but no structural engineer is needed because no walls are moved. Plumbing permit covers the new dishwasher drain (must connect to the sink trap or the main stack with a check valve, per IRC P2722.2), the hot-water supply line (1/2-inch copper or PEX), and the drain vent routing. Electrical permit covers the two SABC circuits (20-amp each, GFCI-protected, countertop outlets spaced no more than 48 inches apart), the range-hood circuit (20-amp dedicated from the panel), and a GFCI outlet for the dishwasher. The building permit includes the range-hood wall penetration detail (duct routing, exterior termination cap, backdraft damper). Plan review is 2–3 weeks because there's no structural review — the building inspector just verifies that the range-hood duct penetration is sealed and meets code. Inspections: rough plumbing (dishwasher drain connection), rough electrical (SABC circuits and range-hood circuit), drywall (after walls are closed around the new duct), and final. Timeline: 4–5 weeks from application to final inspection. Permit fees: building $150, plumbing $180, electrical $180, total $510. Contractor cost: $8,000–$15,000 depending on whether cabinets are modified to fit the dishwasher. The key Concord-specific detail: the electrical plan must show the two SABC circuits clearly labeled and must show GFCI protection at every countertop outlet; if the electrician submits a plan that doesn't show this, it will be kicked back by the plan reviewer.
All three permits required | No structural engineer needed | New dishwasher drain + hot-water line | Two 20-amp small-appliance circuits required | GFCI protection on all countertop outlets | Range-hood venting (wall penetration, 6-inch duct) | 2–3 week plan review | 4 inspection stages | Permit fees: $510 | Contractor cost: $8,000–$15,000 | No RRP if post-1978

The three-permit sequence: why Concord requires separate building, plumbing, and electrical approvals

Concord's Building Department enforces the 2015 IBC by separating permitting authority into three branches: building (structural, fire, roof/wall penetrations), plumbing (water supply, drainage, venting, gas), and electrical (circuits, outlets, fixtures). This is standard in most New Hampshire municipalities but creates a longer timeline because each permit is reviewed sequentially, not in parallel. Why? The building inspector must approve the floor plan and structural changes first (so the plumbing and electrical inspectors know where the walls will be); then plumbing and electrical review in parallel. If the building plan shows a wall removal with a 12-inch beam, but the plumbing plan still shows a drain line running through the beam's support column, the plumbing plan gets kicked back until it's redrawn.

In practice: you submit all three applications together. The building permit is stamped 'approved' or 'rejected with comments' within 5–7 business days. Once building is approved, the city sends the plumbing and electrical plans to their respective plan reviewers (often consultants, not city staff). Those reviews happen in parallel and take another 5–7 days. If either is rejected, you revise and resubmit that permit only. This means a worst-case scenario is 3–4 rejections and resubmittals, stretching the plan-review phase to 4–5 weeks. Once all three are approved, you can schedule the first inspection (rough plumbing) immediately.

The fee structure reflects this separation. Building permit: $150–$300 (based on construction valuation, typically 1.5% of estimated cost). Plumbing permit: $150–$250. Electrical permit: $150–$250. Total permit cost for a $20,000 kitchen: roughly $600–$800. This is higher than a city that bundles kitchen permits into a single omnibus fee (some cities charge $300 flat for any kitchen remodel), but Concord's separation forces more rigorous review and catches code violations earlier.

Lead-paint RRP compliance in Concord: what triggers it, what it costs, and why inspectors care

If your home was built before 1978, federal EPA Rule 40 CFR 745 (the Renovation, Repair, and Painting Rule, or RRP Rule) requires that any contractor disturbing more than 6 square feet of painted surface must be RRP-certified, must notify occupants of the hazard, and must contain and minimize dust using specific techniques (plastic sheeting, HEPA vacuums, wet-wiping, clearance testing). In Concord, this applies to kitchens because wall removal, cabinet installation, and drywall work all disturb old paint. The Concord Building Department does not directly enforce the RRP Rule — that's the EPA's jurisdiction — but if an inspector observes RRP violations (open drywall work without containment, visible dust on windows or adjacent rooms), they can issue a stop-work order and a notice of violation.

What it costs: RRP compliance for a full kitchen typically runs $1,500–$3,000. This includes containment setup (plastic sheeting, negative air machine), lead-safe work practices (wet-wiping instead of sanding, HEPA vacuums), and a clearance test by an EPA-certified lead inspector at the end (typically $400–$600 per test). Many contractors build this into the bid; if yours hasn't mentioned it and your home is pre-1978, ask explicitly whether they are RRP-certified and what their containment plan is. If they say 'no problem, we'll just be careful,' they are exposing you to liability. The EPA can fine homeowners and contractors $100–$500 per day for RRP violations, and if anyone in the household (especially children) is tested for elevated blood-lead levels after the renovation, the contractor could be liable for remediation costs.

Verification: before signing a contract, ask the contractor for their RRP certification (it's an EPA-issued ID number, searchable on the EPA website). Ask to see photos of similar pre-1978 kitchen jobs they've done and their clearance-test reports. If the contractor is not RRP-certified, hire a separate RRP-certified firm to manage the work (a lead abatement company). The cost is higher, but it protects you legally and ensures the work is done right.

Common questions

Do I need a permit to replace my kitchen cabinets and countertops if I'm not moving anything?

No. Cabinet and countertop replacement, if the sink stays in the same location and no new electrical or plumbing work is done, is cosmetic and exempt from permitting in Concord. You do not need to apply for a permit. However, if the new cabinets require a new outlet or if you're moving the sink even slightly, a permit is required.

What if I remove a wall in my kitchen? Do I really need an engineer?

Yes. If the wall is load-bearing (most walls perpendicular to the rafters in a one-story home are), Concord's Building Code requires a structural engineer's letter and beam-sizing calculations before the building permit will be approved. The cost is $400–$1,200, but it is non-negotiable. If you skip it, the inspector will stop the work and fine you.

How long does it take to get a kitchen permit in Concord?

Plan review takes 2–4 weeks if the plans are complete and code-compliant on first submission. If there are rejections or clarifications needed, add 1–2 weeks per revision. Once all three permits (building, plumbing, electrical) are approved, inspections begin and take 3–4 weeks depending on the scope. Total time from application to final inspection: 5–8 weeks.

Can I do the kitchen work myself, or do I need a licensed contractor?

New Hampshire allows owner-builders for owner-occupied homes, so you can perform the work yourself if you own the home and live in it. However, you still need permits and must pass inspections. Electrical and plumbing work must meet code, so if you are not experienced, hire licensed electricians and plumbers for those scopes; you can do demolition, framing, and finish work. Concord inspectors will not care who did the work, only that it meets code.

My kitchen is on the second floor. Does that change the permit requirements?

No. Second-floor kitchens are permitted the same way as first-floor kitchens. The main difference is that plumbing vent stacks may be routed differently (they must still clear the roof or tie into an existing vent), and the inspector will verify that drain slopes are correct even with the added vertical drop. This does not exempt you from permits or change the fee.

If I'm just swapping out my gas range for an electric one (or vice versa), do I need a permit?

Yes. Changing a gas appliance to electric (or electric to gas) requires electrical and/or plumbing permits. If you're switching to electric, you need a new 240-volt circuit (20 amps minimum for an electric range), and the gas line must be capped and abandoned per code. If you're switching to gas, a new gas line must be run and inspected. These are not cosmetic changes and will be flagged during a home inspection or resale.

What is a small-appliance branch circuit, and why does my electrician keep asking about them?

Per IRC E3702, kitchens require two dedicated 20-amp circuits for countertop outlets (one for each countertop area). These are called small-appliance branch circuits (SABC) and must not be shared with other loads. They power coffee makers, toasters, and small appliances. Every countertop outlet must be GFCI-protected and spaced no more than 48 inches apart. If your electrical plan doesn't show these two circuits clearly, Concord's plan reviewer will reject it and you'll have to revise.

I'm moving my sink 3 feet to the left. Does that require a plumbing permit?

Yes. Moving a sink, even 3 feet, requires a plumbing permit because the drain line (trap and vent) must be rerouted and inspected. The inspector will verify that the new drain slopes correctly (1/4 inch per foot) and that the vent stack connects properly. Do not do this without a permit.

My house was built in 1975. What does that mean for my kitchen remodel?

It means lead-paint disclosure and RRP compliance are required. Before any renovation work (demolition, wall removal, cabinet removal) can begin, you and your contractor must sign a lead-hazard notification form, and the contractor must be EPA RRP-certified. The work must include containment (plastic sheeting, negative air machines) and clearance testing. This adds $1,500–$3,000 to the budget but is legally required and protects your family from lead dust exposure.

Can I start my kitchen remodel before the permits are approved?

No. Concord law prohibits work from beginning before all permits are approved and inspections scheduled. If you start before permits are issued and the city finds out (through a neighbor complaint or routine inspection), you will receive a stop-work order and a $100–$500 fine. Do not begin demolition or any structural work until you have signed, approved permits in hand.
