What is a punch list and final walkthrough in a new home build?

Before you close on a new home and take the keys, two steps stand between you and whatever the builder left unfinished or did wrong. The final walkthrough is the walk you and your builder take through the completed home, room by room, to find anything that is missing, broken, or not built to spec. The punch list is the written record of every item you find, the list the builder agrees to fix before closing. Done well, they catch the small flaws and the real defects while the builder is still standing right there and still legally responsible.

This is the moment you have the most pull. Once you close and move in, fixing things becomes a warranty claim instead of a checklist item. A careful walkthrough and a complete, written punch list are the cheapest insurance you have on a build that may cost several hundred thousand dollars.

What a punch list is

A punch list is the written, itemized list of work a builder must complete or correct before a new home is considered done. The name comes from the old practice of punching a hole next to each item as it was finished. Every item is specific, tied to a location, and checked off only when fixed.

A good punch list is detailed, not vague. Instead of "fix the kitchen," it reads "scratched cabinet door, lower left of sink" and "GFCI outlet left of range does not reset." Typical entries on an Arizona build include:

• Finish defects: paint drips, drywall dings, chipped tile, scratched countertops, gaps in trim or baseboard.
• Things that do not work: outlets with no power, switches wired to the wrong light, a toilet that runs, a window that will not lock.
• Missing or incomplete work: a missing cabinet pull, an unpainted closet, a door that was never hung, grout left out of a tile seam.
• Climate-specific items: weak airflow from an HVAC register, gaps around exterior doors that leak the cooled air your Arizona summer depends on, or a leak at an irrigation or hose connection.

Each item should say what is wrong, where it is, and what "fixed" looks like. The clearer the entry, the harder it is for anyone to call it done before it really is.

What a final walkthrough is

A final walkthrough is the in-person inspection where you and the builder go through the finished home and create the punch list together. It usually happens near the end of the build, often a week or so before closing, after the home has passed its city inspections and the certificate of occupancy has been issued or is in hand. That certificate is the city's sign-off that the home is safe and legal to live in.

During the walkthrough you test things, not just look at them. Open and close every door and window. Flip every switch. Run every faucet and flush every toilet. Turn on the air conditioning and feel the airflow at each register, which matters in a climate where the AC carries the house for months. Open cabinets and drawers. Check floors and counters for scratches in good light. Look up at ceilings and down at grout lines. Bring a phone to photograph each issue and a notepad, or have the builder log items as you go.

Take your time and do not let anyone rush you. This is the one inspection where the builder writes down what they owe you and signs onto fixing it. A thorough walkthrough often turns up a few dozen small items on a custom home, which is normal, not a sign of a bad builder.

Many buyers bring help. You can hire an independent home inspector to walk the home with you for a few hundred dollars, and their trained eye often catches things you would miss, like a vent that was never connected or a slope that drains water toward the house. On a custom build you may also do an earlier walkthrough before drywall goes up, called a pre-drywall walkthrough, to check framing, wiring, and plumbing while they are still visible. The final walkthrough then focuses on finishes and function, since the bones of the house are already closed in.

How the two work together before closing

The walkthrough and punch list work as a pair: the walkthrough finds the problems, and the punch list holds the builder to fixing them before you close. The sequence is straightforward. You walk the home, you list every defect, the builder agrees to a timeline, and you both sign the list so it becomes a record.

Most of the time the builder completes the punch list before closing. If a few items need a back-ordered part or more time, you can agree in writing that those specific items will be finished after closing, with a date attached. Get that in writing. A handshake promise to "take care of it later" is the one most likely to fade once the sale closes.

This step also feeds your warranty. Anything left after closing, and any new defect that surfaces later, moves into your builder warranty: typically one year on workmanship, two on systems, ten on structure. The walkthrough is simply the first and easiest pass at quality, done while the cost of fixing is lowest and the builder is most responsive. Keep the signed punch list with your warranty paperwork, since it proves what condition the home was in on day one.

Why it matters and what backs you up in Arizona

A strong walkthrough and punch list matter because they are protected by real Arizona law if a builder walks away from the list. Arizona builders must be licensed, and the Arizona Registrar of Contractors, the state agency that licenses and disciplines builders, can act against a licensee for "failure in a material respect to complete a construction project" or for not building "in a professional and workmanlike manner," both grounds set out in A.R.S. 32-1154. So a punch list a builder refuses to honor is not just a private disagreement. It can be a licensing matter.

There is a deadline that makes early action smart. If you do need the state to step in, A.R.S. 32-1162 requires an ROC complaint on a new home to be filed in writing within two years after the earlier of close of escrow or actual occupancy. Behind that sits Arizona's implied warranty of workmanship and habitability, which courts apply to every new home to "protect innocent purchasers and hold builders accountable for their work."

The practical takeaway is to treat the walkthrough as a real inspection and the punch list as a binding document. Be specific, put everything in writing, photograph each item, and keep a signed copy. The list you build that day is the record you will lean on if a fix is ever in dispute. Before you sign anything that says the walkthrough is complete, confirm that every item is either fixed or written down with a firm date, and never sign off on work you have not actually seen finished. A few extra minutes here can save months of back-and-forth after you move in.
