New Hampshire's code-edition choice for new building permit requests ends December 31, 2026, giving Merrimack homeowners planning a deck a reason to settle their plans before the year turns. Villandry Home & Outdoor Living offers residential deck design and permit acquisition there; the deadline concerns the code basis for applications, not a newly announced company program.
The state building-code notice says applicants may submit requests under the applicable 2021 or 2024 editions during a six-month period that began July 1. From January 1, 2027, new requests must follow the newly listed codes, which include the 2024 International Residential Code with New Hampshire amendments. State law does not allow an applicant to mix requirements from the two editions during the temporary choice period. The issuing authority still determines what documentation a particular project needs.
This is a deadline for the code edition used in a request, not a deadline to finish construction or an order to rebuild an existing deck. Filing under an earlier edition does not itself mean a plan will be approved. An owner with a pending permit should check its status with the issuing department rather than presume that the January change cancels or approves it.
For a deck still on the drawing board, the first decision is the scope of work. A new platform, a full replacement and an alteration to an existing deck are different proposals to describe to the building department. The plan should show the layout and intended use, along with how the deck meets the house, where supports and stairs go, and what remains of any older structure. A generic sketch from another property cannot resolve those site questions.
The state notice does not identify a particular deck dimension that changed between the two editions. It would be misleading to turn the transition into a claim that every railing, footing or stair now has a different rule. What matters before pricing or submitting a design is that the plans use one applicable code basis and reflect the work that will actually be reviewed. A late change to the layout can also change what the applicant needs to document.
Merrimack has a separate local submission and inspection process. Its Building Division directs permit applicants to OpenGov, and its inspection instructions say requests must be made through that portal rather than left by phone voicemail. Work scheduled for inspection must be finished and accessible. These local steps do not extend the state's code-edition choice or guarantee a permit simply because an application is in the portal.
The town lists deck and porch pier footings among a few cases that may qualify for a virtual inspection. Prior approval is required and the decision rests with the department. A homeowner should not plan on that option as a substitute for a required inspection. Outside Merrimack, applicants need the relevant town's own instructions rather than assuming this portal or inspection practice applies statewide.
The company's residential decking page describes design consultation, 3D modeling, permit acquisition, construction and a final walkthrough for new and replacement decks. Those are descriptions of an existing service, not evidence that Villandry wrote the new code or has a special approval route. For an individual project, the homeowner and contractor should confirm who prepares and submits the application and what the local reviewer expects.
The practical sequence is to establish the intended deck and application timing, ask the issuing authority which edition governs, and bring the drawings into line with that answer before relying on a construction schedule. Villandry Home & Outdoor Living can discuss a proposed residential deck in Merrimack. The state notice and the town building office remain the sources for the deadline and the approval process.
