Working With a Builder: Locks in a New-Build Handover

A new build has a rhythm that rewards preparation: the frame goes in, the first fix follows, the second fix follows that, and the hardware is fitted on doors, in a sequence, near the end. There’s a moment, right at the transition between the last of those steps and the owner’s arrival, when the builder pulls out and the household moves in — and where access hardware sits in that handover decides whether the first month is calm or full of calls.

This is written for both sides of that exchange: the builder who wants a clean completion and the owner who wants an entrance that works on move-in day. The subject is the door, and specifically the documentation, sequence and handover habits that make new-build access work.

Where locks belong in the build sequence

Hardware entering the site is not the same as hardware being fitted, and fitted is not the same as verified. The useful sequence:

1. Specified with the door, not after it. Door specification and lock specification should be one conversation, because they constrain each other — thickness, preparation, mortise standard, and the handle mechanics all live at that intersection. A build that chooses the door first and the lock later pays for the disagreement later. Our door compatibility guide exists to be handed to whoever is making that decision.
2. Delivered before doors hang. The supplier-side version of this sequence is covered in our storage article: hardware arriving late turns installers into re-schedulers and doors into bottlenecks.
3. Fitted after painting, before handover cleaning. Painters fill and repaint lock apertures more often than anyone wants; on-site storage keeps the locks safe until the messy work is finished, and the last cleaning pass leaves the entrance genuinely new.
4. Verified with the whole entrance. Alignment, latch line, and the operation of every method — run at the door, with the actual door, in that same week.

The documentation bundle that belongs to the owner

What the builder should clear, and what the owner should set

The two sides of a new-build handover split the work cleanly if they’re planned:

• Builder-side: every construction credential retired, mechanical keys all accounted for, door mechanics adjusted after the move-in damage of trades has stopped, and whatever snagging touches the entrance completed before the owner takes the keys. A builder who leaves their site access active because “the owner might need us” is leaving the exact class of credential the new-build access system is designed to prevent.
• Owner-side: the installation and documentation bundle reviewed (not just filed), every method tested in the first week, and the household’s own access model chosen — because even in a fully smart home, a new household needs to think through who gets which method. Our first-year maintenance schedule begins on move-in week, and it works better when the entry starts clean.

For developers and project buyers

At multi-unit scale, this handover logic becomes the difference between a smooth completion and a support queue. Three specifications make it work:

• Standardize the family, not every door. One lock family per door type across the development keeps the documentation teachable, the spares shared, and the resident learning curve short — our property-type guide maps this for builders choosing across residential and commercial units.
• Own the documentation per unit. A handover pack per unit: model sheet, key count, credential reset procedure, and the buyer’s contact for support. The unit’s documentation shouldn’t be a single copy in the project office.
• Clear construction access as an operation. On a large build, dozens of construction credentials accumulate. The handover operation retires them in one sweep — and the fact that this is possible at all is a property of the per-credential model, not a bonus: it’s the reason our ranges document credential capacities and per-user management in the first place.

Common questions

Should the builder fit smart locks or standard locks on new builds?

That’s the buyer’s decision, and increasingly it’s smart — but whichever the choice, the door preparation should assume the decision’s consequences: preparing a door well for the lock family that will actually live on it (smart deadbolt, mortise for aluminum, purpose-built for glass) prevents the retrofit-preparation mismatch that costs real money later. For a developer planning this across units, the honest conversation with the door and lock suppliers together, at the specification stage, is worth more than any post-completion fix.

What about warranty and support responsibilities at handover?

They’re set by the supply terms of your project, and our supply conversations define them per order — we don’t publish a single policy in articles, and any builder reading a brochure-level promise should ask the question directly of their supplier. What’s worth doing at handover regardless: the buyer’s first-year support path documented on one card. Most first-year issues are ordinary questions — a code change, a battery, an app pairing — that become warranty disputes only when nobody wrote down who to ask.

How do builders handle tenant-occupied new builds?

The same logic, run per unit, with the credential clearing operation done unit by unit against the tenancy start date. For a builder fitting out a rental development, our turnover article describes the ongoing rhythm the handover is really preparing for — because in a rental building, move-in day is the first turnover of many, not a one-off event.
