Construction Loan Requirements in New Hampshire
Last updated: October 29, 2026. State rules checked against the primary sources listed at the end of this guide.
To build with a construction loan in New Hampshire, you generally need NHDES approval of a septic design if there's no sewer, a local building permit where your town enforces the State Building Code, any shoreland permit for lots near public waters, and a flood-zone check. There's no state license for general contractors, so lenders review your builder closely. Your lender adds its own credit, appraisal, and draw requirements.
Here's what each step looks like in New Hampshire, with links to the state sources.
Key takeaways
- Builder: no state GC license; licensed electricians and plumbers are required.
- Code: 2024 codes from July 1, 2026, with a choice of 2021 or 2024 through December 31, 2026.
- Site: NHDES septic approval; shoreland permit near public waters.
- Liens: lien lasts one hundred twenty days and must be secured by court attachment.
- Closing: attorneys or title companies; transfer tax on buyer and seller.

What do lenders require for a construction loan?
Most construction lenders look for:
- A credit, income, and asset review, much like a regular mortgage
- Enough equity, from cash, land you own, or both. See how land equity works.
- An approved builder with a license or registration, insurance, and references. See builder approval.
- Plans, specifications, and a line-item budget, often with a contingency line
- An "as completed" appraisal of the lot and finished home together
- Title work, a survey, and insurance, including builder's risk during construction
- Reserves for cost overruns, depending on the lender
Requirements vary by lender and loan program. FHA, VA, USDA, and conventional loans each have their own rules.
Does my builder need a license in New Hampshire?
New Hampshire doesn't license general contractors at the state level. The Office of Professional Licensure and Certification licenses trades such as electricians and plumbers (NH OPLC laws and rules). Because there's no state builder license, lenders lean harder on their own builder review: insurance, references, financials, and past projects. See how builder approval works.
Since there's no state builder license, being your own general contractor isn't barred by licensing, but licensed trades are still required for electrical and plumbing work, and many lenders won't finance an owner-builder. Read more about owner-builder construction loans.
Which building code applies in New Hampshire?
The State Building Code applies statewide, but towns choose whether to enforce it locally. On July 1, 2026, the code moved to the 2024 International Residential Code and other 2024 codes with New Hampshire amendments. Through December 31, 2026, permit applicants can use either the 2021 or the 2024 codes; starting January 1, 2027, permits follow the 2024 codes (NH State Fire Marshal, State Building Code; RSA 155-A). If your town has no local enforcement, ask your lender what inspections it will require.
Do I need septic approval in New Hampshire?
If there's no sewer, yes. NHDES reviews septic designs and issues an Approval for Construction before the system is built, then an Approval for Operation before it is used. Plans must be prepared by a permitted New Hampshire septic system designer (NHDES septic systems; RSA 485-A:32). Lenders usually want the construction approval before closing.
What about lakefront lots and flood zones in New Hampshire?
Check your lot on the FEMA Flood Map Service Center. If the home sits in a high-risk flood area, the lender will generally require flood insurance. Building within the protected shoreland of lakes, ponds, larger rivers, and coastal waters is regulated under the Shoreland Water Quality Protection Act and can need an NHDES shoreland permit (RSA 483-B).
How are construction loan closings handled in New Hampshire?
New Hampshire closings may be handled by attorneys or title and closing companies. The state real estate transfer tax applies to both buyer and seller when property changes hands (RSA 78-B). Ask your lender who will conduct the closing.
How do mechanics' liens work in New Hampshire?
New Hampshire's mechanic's lien lasts one hundred twenty days after the work or materials are provided, and the claimant has to secure it by a court attachment within that time (RSA 447:9). Lenders collect lien waivers as each draw is paid.
Are there state homebuyer programs for building in New Hampshire?
New Hampshire Housing offers homebuyer programs through participating lenders (New Hampshire Housing). Ask whether a program can be used with new construction before you plan around one.
How do I check that a lender is licensed in New Hampshire?
Search the lender and loan officer on NMLS Consumer Access. The New Hampshire Banking Department licenses non-bank mortgage lenders, brokers, and loan originators (NH Banking Department).
What are the steps to build in New Hampshire?
- Confirm the lot can be built on: access, zoning, flood zone, and septic or sewer.
- Choose a qualified builder and get plans, specs, and a line-item budget.
- Compare lenders and get a Loan Estimate for your project.
