A kitchen remodel touches every part of daily life, from morning coffee to evening cleanup. A clear checklist keeps the project on track, whether you are refreshing a few surfaces or reconfiguring the entire layout. This guide walks you through the key phases: defining how your household uses the space, measuring against industry planning guidelines, hiring a contractor carefully, addressing safety and air quality, and conducting a thorough final walkthrough.

Short version: Start by listing who cooks and any accessibility needs, then measure your space against NKBA recommendations for doorways, work triangle, aisles and ventilation. Hire a contractor using the FTC’s steps: written estimates, references, licensing, insurance and a detailed contract. For homes built before 1978, follow EPA lead-safe rules. Ventilate well during and after work to reduce VOCs, and never make the final payment until every item in the contract checks out.

1. Define Your Household Needs and Accessibility Goals

Before you measure a single wall, think about who uses the kitchen and how. A household with multiple cooks needs wider work aisles, while a family with young children may want lock-out devices on appliances. The University of Kentucky Cooperative Extension’s home accessibility checklist encourages universal design features that make a kitchen safer and more comfortable for people of all ages and abilities. Its publication suggests a clear open space at least 5 feet in diameter for turning, aisles 42 to 48 inches wide, and doorways that are 36 inches wide.

Small changes can make a big difference. The same University of Kentucky checklist recommends task lighting over the sink, stove and other work areas, as well as single-lever faucets or ergonomic dual-handle faucets with a high-arc pull-out spray head and an anti-scald valve. For storage, it points to pull-out shelves, adjustable-height cupboards and lazy Susan turntables. Multi-level countertops with open space beneath let someone work while seated, and rounded countertop corners reduce the risk of bumps. Easy-to-open cabinet doors with single-lever or U-shaped handles help anyone with limited grip strength. If you are planning a full layout change, our workflow and ergonomics guide can help you think through movement patterns.

2. Measure and Plan Against NKBA Guidelines

The National Kitchen & Bath Association publishes planning guidelines that give clear dimensional targets. These are recommendations, not laws, and local building codes always take priority. Still, they are a practical starting point for a functional kitchen. The NKBA’s guidelines reference the 2015 International Residential Code as analyzed by the association.

Doorways and Clearances

The NKBA recommends that the clear opening of a doorway be at least 32 inches wide, which would require a minimum 2-foot-10-inch door. For better access, the access standard suggests a clear opening of at least 34 inches, calling for a 3-foot door. No entry door should interfere with the safe operation of appliances, and appliance doors should not interfere with one another.

Work Triangle and Aisles

In a kitchen with three primary work centers (cooking surface, cleanup/prep sink, and refrigeration), the NKBA says the sum of the three traveled distances should total no more than 26 feet, with no single leg shorter than 4 feet or longer than 9 feet. No work triangle leg should intersect an island or peninsula by more than 12 inches. A full-height, full-depth tall obstacle such as a tall oven cabinet or refrigerator should not separate two primary work centers. Major traffic patterns should not cross through the work triangle.

For work aisles, the NKBA recommends at least 42 inches for one cook and at least 48 inches for multiple cooks, measured between counter frontage, tall cabinets or appliances. A walkway should be at least 36 inches wide. If you are exploring different arrangements, our layout types article explains galley, L, U and island configurations.

Seating and Walkways

Where no traffic passes behind a seated diner, the NKBA suggests 32 inches of clearance from the counter or table edge to any wall or obstruction. If traffic passes behind, allow at least 36 inches to edge past and at least 44 inches to walk past. For seating knee spaces, a 30-inch-high table or counter needs a space 24 inches wide by 18 inches deep; a 36-inch-high counter needs 24 inches wide by 15 inches deep; a 42-inch-high counter needs 24 inches wide by 12 inches deep.

Lighting and Electrical

The NKBA guidelines note that at least one wall switch-controlled light must be provided at the entrance, and a window or skylight area equal to at least 8 percent of the kitchen’s total square footage is required by code. Beyond that, the NKBA recommends that every work surface be well illuminated by appropriate task lighting. For help layering light, see our task lighting and ambient lighting guides.

On the electrical side, the NKBA references code requirements for ground-fault circuit-interrupter (GFCI) protection on all receptacles serving countertop surfaces, on receptacles within 6 feet of the outside edge of the sink, and on outlets that supply dishwashers. Receptacle outlets must not be installed face-up in work surfaces or countertops.

Ventilation

The NKBA recommends a correctly sized, ducted ventilation system for all cooking surface appliances, with a recommended minimum of 150 cubic feet per minute. The code minimum exhaust rate for a ducted hood is 100 cfm, and it must be ducted to the outside. Ducts must have a smooth interior surface, be airtight, have a back draft damper, and be independent of other exhaust systems. Air must not be exhausted into an attic, soffit, ridge vent or crawlspace. When an exhaust hood can move more than 400 cfm, makeup air must be provided at a rate approximately equal to the exhaust rate. The University of Kentucky checklist adds an exhaust fan control switch at the front of the counter, or wherever it is easy to reach when seated.

3. Hire a Qualified Contractor

The Federal Trade Commission offers a step-by-step approach to finding and working with a contractor. Start by checking with friends, neighbors or coworkers who have had similar work done, and look at online ratings and reviews on sites you trust. The FTC also suggests searching the company’s name with words like “scam” or “complaint.” Find out how long the firm has been in business.

Once you have a short list, get written estimates from several firms. The FTC cautions against choosing the lowest bidder automatically; ask for an explanation of any large price differences. Verify that the contractor’s license is current if your state or locality requires licensing. Ask for proof of personal liability, worker’s compensation and property damage insurance, and make sure the certificates are current. Request a list of at least three references with projects like yours, and ask those clients about timeliness, unexpected costs and cleanup.

Before work begins, get a written contract. The FTC says it should include the contractor’s name, address, phone and license number, estimated start and completion dates, a payment schedule, and the contractor’s obligation to obtain all necessary permits. It should also spell out how change orders are handled, list all materials with color, model, size and brand, and describe warranties for materials and workmanship. Ask for a “broom clause” that makes the contractor responsible for all cleanup. If you signed the contract at home or somewhere other than the seller’s permanent place of business, you have a right to cancel within three business days.

4. Address Safety, Permits and Lead-Safe Practices

Most states and localities require permits for building projects, even for seemingly simple jobs. The FTC advises that a competent contractor will get all necessary permits before starting work. Electrical, gas, plumbing and structural changes typically need permits and licensed trades; always check your local rules.

If your home was built before 1978, lead-based paint may be present. The U.S. Environmental Protection Agency’s Renovation, Repair and Painting (RRP) Rule requires that anyone paid to perform work that disturbs painted surfaces in pre-1978 homes be certified and trained in lead-safe work practices. Plan for it whenever painted walls, cabinets or trim will be disturbed. Homeowners doing their own work are generally exempt from the RRP Rule, but the EPA still recommends using lead-safe work practices to protect your family. You can find a lead-safe certified contractor through the EPA’s resources. If you rent out part of your home or operate a childcare center there, the rule does apply to you even as the homeowner.

5. Choose Materials and Manage Indoor Air Quality

New cabinets, flooring, paint and adhesives can release volatile organic compounds (VOCs) into the air. The EPA explains that VOCs are emitted as gases from many solids and liquids, and concentrations can be consistently higher indoors than outdoors. During and for several hours after activities like paint stripping, levels may be many times higher than background outdoor levels.

The EPA recommends increasing ventilation when using products that emit VOCs, meeting or exceeding all label precautions, and using household products according to the manufacturer’s directions. Open windows or use exhaust fans to bring in outdoor air. Do not store opened containers of unused paints and similar materials inside the home. When selecting finishes, look for products that follow low-emission standards, and always follow the instructions for your specific product. For help comparing surface options, see our countertops and kitchen flooring guides.

6. Final Walkthrough and Payment

The FTC stresses that you should not make the final payment or sign an affidavit of final release until you are satisfied with the work and have confirmed that subcontractors and suppliers have been paid. Before you sign off, use a checklist to inspect the job. The FTC’s sign-off checklist includes verifying that all work meets the standards in the contract, that you have written warranties for materials and workmanship, that you have proof subcontractors and suppliers were paid, that the job site is cleaned up and free of excess materials, and that you have inspected and approved the completed work. Ask for lien releases or lien waivers from the contractor and every subcontractor and supplier to protect yourself from mechanic’s liens. Keep all paperwork, change orders and a log of conversations in one place. If a problem arises, try to resolve it directly with the contractor first, then consider contacting your state attorney general or local consumer protection office.

Frequently asked questions

Do I need a permit for a kitchen remodel?

Most states and localities require permits for building projects, even for jobs like decks. The Federal Trade Commission notes that a competent contractor will get all necessary permits before starting work. Always check with your local building department, because requirements vary.

What does the lead-safe rule mean for my pre-1978 home?

The EPA’s RRP Rule requires that anyone paid to disturb painted surfaces in a home built before 1978 be certified in lead-safe work practices. Homeowners doing their own work are generally exempt, but the EPA still recommends using lead-safe methods to reduce lead dust. If you rent out part of your home or run a childcare facility, the rule applies to you.

How wide should a kitchen aisle be?

The National Kitchen & Bath Association recommends a work aisle width of at least 42 inches for one cook and at least 48 inches for multiple cooks. A walkway should be at least 36 inches wide. These are planning recommendations, and local building codes may have different requirements.
