Keene, NH?

Keene kitchen remodels — the key details

Keene's Building Department enforces the 2015 IRC for all residential kitchens, and the city does not have discretionary exemptions for 'minor' plumbing or electrical work. Any relocation of a sink, dishwasher, or gas cooktop requires a plumbing permit and plan approval. Any new circuit, outlet addition, or recirculation of existing circuits requires an electrical permit. Any removal or relocation of a load-bearing wall requires a building permit and a signed letter from a licensed engineer or architect confirming beam sizing (or no beam is needed). Range-hood ducting that penetrates an exterior wall requires a building permit showing the duct type, termination cap detail, and wall penetration flashing. The city's online portal (accessible via the Keene city website) allows you to upload plans electronically, but hard copies are still accepted at City Hall. Most full kitchen remodels end up with three simultaneous permits: building, plumbing, and electrical. Mechanical permits are required only if you're adding or replacing a range hood with exterior ducting (which triggers HVAC code compliance). Lead-paint disclosure is mandatory for any pre-1978 home; failure to disclose can result in federal fines up to $16,000 per violation.

Keene's most common kitchen-permit rejection is failure to show two dedicated small-appliance branch circuits (per IRC E3702) on the electrical plan. The code requires two 20-amp circuits serving only countertop outlets, and they must be at least 6 feet from the sink. Every outlet within 6 feet of a sink must be GFCI-protected, and no single outlet may be more than 48 inches from another (IRC E3801). Many homeowners and even some contractors miss these requirements, resulting in plan rejection and a 2–3 week resubmission delay. A second common issue is range-hood ducting: Keene requires the duct to terminate at an exterior wall, not into an attic or vented soffit, and the termination must include a weather cap and flashing detail. If your plans show ducting routed through a soffit or into the attic, the city will reject them. Load-bearing wall removal without engineering is an automatic rejection — the city will not issue a building permit without proof the load is supported. This requires a licensed structural engineer (cost: $500–$1,500), but it's non-negotiable.

Keene permits full kitchen remodels under owner-builder rules: the homeowner may pull the permits, but the actual plumbing and electrical work must be performed by licensed contractors. You cannot do the plumbing or electrical yourself, even if you own the home. You can perform demolition, framing, painting, and finishing work. Plumbing contractors must be licensed in New Hampshire; electrical contractors must hold a valid NH journeyman or master license. Gas-line work requires a licensed plumber with a gas-piping endorsement or a licensed HVAC contractor certified for gas. If you hire an unlicensed tradesperson and the inspector discovers it, the city will stop work and may require removal and re-do by a licensed contractor at your expense. Plan review for a typical full kitchen remodel (walls moved, plumbing relocated, new circuits, range hood ducted) takes 3–6 weeks. Once approved, you have 12 months to begin work; if you don't start within that window, you must reapply and pay the permit fee again. Inspections happen in sequence: rough plumbing (before walls close), rough electrical (before drywall), framing inspection (if walls are moved), drywall final, and final building inspection. Electrical and plumbing each have their own final inspections, so you're looking at a minimum of 4–5 inspection appointments.

Keene's permit fees for full kitchen remodels are based on valuation: the city uses a formula of roughly 1–1.5% of the project cost for the total building permit fee, with separate fees for plumbing and electrical. A $40,000 kitchen remodel typically costs $400–$600 for the building permit, $300–$500 for plumbing, and $250–$400 for electrical — total $950–$1,500. These are estimates; the city calculates exact fees based on square footage of work, fixture count, and circuit additions. Plumbing fees are usually per-fixture-point (sink, dishwasher, disposal) plus a base review fee. Electrical fees are per-circuit or per-outlet. If you need structural engineering for a wall removal, add $500–$1,500. Inspection fees are typically included in the permit cost; re-inspections (if work fails) are often $75–$150 per re-inspection. Payment is due when you submit the permit application; most of Keene's system accepts credit card or check. The city does not issue refunds if you cancel after approval, even if you haven't started work.

New Hampshire has no statewide code-adoption lag, and Keene enforces the 2015 IRC without significant local amendments beyond standard sizing and spacing rules. The city does require that any plumbing work comply with the NH Department of Environmental Services water-supply rules, which means if you're on a private well, you may need a well-flow test or backflow preventer before any plumbing work begins. The city does not have a historic district overlay that would apply to most kitchens (though if your home is listed on the National Register, you may face exterior cladding restrictions if the kitchen window changes). Keene's climate (Zone 6A, 48-inch frost depth, granite soil) means that any range-hood duct routed through an exterior wall must include vapor barriers and thermal break to prevent condensation and freeze-thaw damage in winter — the inspector will look for this detail on plans. If you're replacing windows or doors as part of the remodel (enlarging or relocating), a separate window/door permit is required; Keene requires ENERGY STAR certification for any replacement window or door in residential work.

Three Keene kitchen remodel (full) scenarios

Keene's two-circuit small-appliance requirement and why it's the #1 rejection reason

IRC E3702 requires that kitchens have two or more 20-amp branch circuits that serve only countertop outlets. These two circuits cannot be used for any other receptacles in the home — no hallway, no bathroom, just countertop. The intent is to prevent overloading from small appliances like toasters, coffee makers, and blenders running at the same time. Keene enforces this strictly, and inspectors routinely reject kitchen permit plans that show countertop outlets on the regular 15-amp general-purpose circuits. If your kitchen plan doesn't clearly show two separate 20-amp circuits dedicated to countertop outlets, Keene will reject it and ask you to resubmit. This often surprises homeowners and even some contractors because it seems like a minor detail, but it's fundamental to kitchen wiring.

When you're designing the new kitchen, you must also follow the spacing rule: no outlet can be more than 48 inches from another outlet along the countertop, measured horizontally. This means counters longer than 48 inches need at least two outlets. Island counters are treated the same way — they must have their own circuits and outlet spacing. Every outlet within 6 feet of the sink must be GFCI-protected. If your island has a prep sink, all outlets on that island must be GFCI. If your countertop perimeter is 20 feet long, you'll need at least five outlets spaced no more than 48 inches apart, and all five must be GFCI if any are within 6 feet of the main sink.

On your electrical permit plan, the inspector wants to see a clear legend showing which outlets are on which circuit. Many rejection letters say something like 'Countertop outlet spacing does not meet IRC E3801' or 'Two small-appliance circuits not clearly identified on plan.' To avoid this, number your outlets (O1, O2, O3, etc.) and create a table: 'O1–O5 on 20A Circuit 3, O6–O8 on 20A Circuit 5, Island outlets O9–O10 on 20A Circuit 7 (GFCI).' This takes two minutes and almost always prevents rejection. If you're hiring an electrician to pull the permit, make sure they understand this requirement and include it on their plan.

Range-hood ducting in Keene's climate — why exterior termination and thermal breaks matter

Keene is in IECC Climate Zone 6A, with a 48-inch frost depth and winter temperatures that regularly drop to 20 below zero. Range-hood ducts that terminate in the attic or soffit will allow warm, moist air from cooking to condense on cold surfaces inside the attic, leading to mold, rotting framing, and ice dams. The IRC requires that range-hood ducts terminate at the exterior of the building (not the attic) and must be vented with a damper and cap. Keene inspectors will not approve plans showing attic or soffit termination, and some inspectors will actually reject the duct if they see it during rough inspection.

When you're designing the exterior termination, the inspector will look for a weather cap (backflow damper) and flashing. The duct should exit through the exterior wall at a slight downward angle, with the cap positioned to shed water and prevent bird entry. Many installers use a simple 90-degree elbow with a cap, but better practice (and what Keene often expects) is a dedicated hood-vent cap with a motorized damper that opens when the hood is on and closes when it's off. This prevents outside air from entering the home when the hood is idle. If your duct passes through an exterior wall in Zone 6A, thermal loss is significant, so some contractors wrap the duct section outside the wall with insulation. Keene doesn't mandate this, but it prevents condensation buildup in the duct itself on very cold nights.

On the plan, show the duct size (typically 6 inches for a standard 30-inch range hood, 7 or 8 inches for larger hoods), the routing from the hood to the exterior wall, any elbows or flex-duct sections (minimize these — they create friction loss and noise), and the exterior cap detail. If you're using flex duct, the plan should note that it's insulated flex. If you're using rigid galvanized duct, note that. Keene wants to see this detail because improper ducting leads to poor performance and moisture problems. A common mistake is using a duct that's too small or too long with too many bends — the range hood will be noisy and ineffective, and moisture will condense in the duct and run back into the hood or into the wall. Keene's building code doesn't specify duct diameter, but the IRC requires ducts to be sized for the CFM (cubic feet per minute) of the hood. A 400 CFM hood typically needs a 6-inch duct; a 600 CFM hood needs a 7-inch duct. Your hood manufacturer will specify this; put it on the plan.
