New-home and renovated-home discounts
How insurers define a new or renovated home, which upgrades earn a credit, how fast the credit fades, and what paperwork gets it onto your policy.
Many insurers take a percentage off the premium for a home built in the last 10 to 15 years, and some give a smaller credit when you replace the plumbing, wiring, heating or roof in an older house. The credit rarely applies on its own: you usually have to ask for it, the insurer's definition of "new" varies, and the credit shrinks every year the house ages. If you bought a new build or finished a major renovation and your premium did not drop, your file may still show the old year built or the old systems.
The National Association of Insurance Commissioners puts the underwriting logic plainly: new homes may qualify for discounts, older homes may not qualify for preferred programs, and insurers may require older homes to have updated heating, plumbing, wiring and roofing (NAIC). Everything below is about turning that general rule into a credit on your declarations page.
What counts as "new"
There is no industry-wide cutoff. Each insurer files its own age bands, and the credit usually steps down as the house moves through them. These are the windows insurers advertise on their own sites, as recorded in our profiles in 2026:
| Insurer | How it describes the credit |
|---|---|
| Horace Mann | Year-of-construction discount for homes built in the last 10 years |
| AAA - CSAA Insurance Group | New-home discount for houses up to 10 years old, shrinking as the home ages; varies by club |
| American Family Insurance | Age-of-home discount for homes under 15 years old |
| Liberty Mutual | A "new or renovated home" discount, plus a separate new-roof discount |
| Nationwide | Credit for renovating plumbing, heating, cooling or electrical systems |
| NYCM Insurance | Renovation discount for homes at least 20 years old with a documented new roof and a heating system replaced within 10 years |
Smaller and regional insurers use the same idea with different numbers: "under 15 years" is common among Farm Bureau and regional mutuals, Farm Bureau Insurance of Michigan counts dwellings 30 years old or newer, and the Massachusetts carriers Arbella Insurance and Safety Insurance list new-home credits of up to 20% and up to 18%. Those maximums are caps for the newest homes. Read them as a ceiling, not a typical result.
Two practical consequences follow. A house that is 11 years old may qualify at one company and not at another, so the quote that looked high on a "fresh" house may be one that has already aged out. And the year built that the insurer has on file matters more than the year you think it was built. Check the date on your quote against your closing paperwork or county record, because a wrong year, in either direction, is rated like a fact.
What counts as "renovated"
Renovation credits are narrower than new-home credits, and they reward the systems that cause expensive claims, not cosmetics. A new kitchen earns nothing by itself. Insurers look for:
| Upgrade | What the insurer usually wants to see |
|---|---|
| Roof replacement | Invoice or permit with the install date, shingle or metal product name, and the final inspection if the town requires one. This is the largest single lever; see how roof age and material affect premiums |
| Plumbing | Year replaced and the material: PEX, copper or CPVC in place of galvanized or polybutylene |
| Electrical | New panel and wiring, with the permit sign-off; it also removes old panel brands that some insurers refuse |
| Heating and cooling | Install date and a contractor invoice |
| Water shutoff or leak detection | Device model and installation date; usually a separate protective-device credit |
American Family Insurance describes its renovated-home discount as plumbing, electrical and heating replaced within 15 years. NYCM requires a documented new roof and a heating system replaced within 10 years on a house at least 20 years old. Insurers differ on whether they need every system updated or only some, and whether a partial update, such as a new panel but old wiring in the walls, counts. Ask before you pay for an upgrade you are doing partly for the insurance credit.
For homes where the insurer wants proof of condition, a four-point inspection report records the roof, electrical, plumbing and HVAC in one document. If you have just renovated, the inspection report plus your invoices is the best package to send.
"New home," "new construction" and "new purchase" are different credits
Quotes often list three things that sound alike.
- New home or new construction. The house was built recently. This depends on the year built.
- Renovated or updated home. An older house with documented new systems. This depends on the install dates.
- New purchase or home buyer. You bought the house recently, whatever its age. Nationwide lists a credit for buying a home within the last 12 months, NYCM Insurance a home buyer discount for a purchase within 12 months, and Horace Mann a new-home-buyer discount for people who buy within their first year as a client.
A buyer's credit lasts a year or two and is tied to the transaction. It does not carry into the third renewal the way a lower rating for a newer roof does. Newly built homes can earn both, so ask the agent to itemize them.
Storm credits that come with newer construction
In hurricane states, "newer" can mean something more specific than age: the building code under which the house was built. Florida's wind mitigation inspection form (OIR-B1-1802) asks whether the home was built to the Florida Building Code (2001 or later). Homes from 2002 and 2003 need a permit application dated after March 1, 2002. That answer, with roof deck attachment, roof-to-wall connections and opening protection, feeds the credits against the hurricane portion of the premium (wind mitigation inspections and discounts, Florida).
Alabama set benchmark discounts for homes built to the 2006 International Residential Code hurricane provisions: 20% of the hurricane premium, with higher benchmarks for each FORTIFIED level, according to the Alabama Department of Insurance's Bulletin 2016-07 (Alabama). Louisiana requires insurers to give an actuarially justified discount for FORTIFIED homes under La. R.S. 22:1483 as amended in 2023 (Louisiana). A new build in one of these states can capture credits that an older house would have to pay a contractor to earn. If you are planning a new build, The FORTIFIED Home standard and insurance discounts explains why designation has to be decided before the roof goes on.
The catches
The credit fades. Age bands move forward every year. AAA says its new-home discount shrinks as the home ages, and some regional insurers' credits step down at each renewal. Budget for the savings to be largest in year one.
Some renovations raise the premium. The NAIC warns that a new wood-burning fireplace or a wooden deck can have the opposite effect of a discount. Add a pool, a second story or a finished basement and the replacement cost rises too. If you finish a renovation without telling the insurer, you can end up with a limit based on the house you used to have. Under the ISO HO-3 (form HO 00 03 05 11), replacement cost settlement on the dwelling applies if you carry at least 80% of its replacement cost at the time of the loss, and below that the payment is prorated. Your insurer's own form may differ. insuring a home during a renovation covers coverage during the work, and the home replacement cost estimator gives a starting point for the new limit.
Credits do not always stack. AAA notes that its discounts are not cumulative, and other rating plans cap combined credits or apply them in sequence. A 10% credit and a 5% credit are not 15% in every plan.
A hypothetical: new roof, new panel, new limit
Say your 24-year-old house carries a $2,800 annual premium on a $350,000 dwelling limit. You spend $14,000 on a new roof and a new electrical panel. Say your insurer's roof-age factor drops the premium by 9% and a renovation credit takes off another 4% (invented numbers; real credits vary). That is roughly $2,800 less about $364, or $2,436. But the work also increased the house's value and finish level, so you raise the dwelling limit to $375,000, and the premium rises by about 7% from the larger limit, back to about $2,600. The net saving is around $200 a year, not $364. The extra limit is the right outcome, because it keeps you from being underinsured, but know that it will offset part of the credit. The roof and mitigation upgrade payback calculator shows how to compare an upgrade's cost with its savings.
How to get the credit onto your policy
- Ask your agent for the insurer's discount list by name. The question "what discounts apply to a home like this?" gets a generic answer. Ask specifically about new-home, renovated-home, new-roof and home-buyer credits.
- Verify the home's file. Confirm the year built, the roof age and material, and which systems are marked as updated.
- Collect documents. Permits and final inspection sign-offs, contractor invoices with dates, product names for the roof and any impact-rated materials, panel and wiring details.
- Send them in writing and request a re-rate effective from the date of the work, not only from the next renewal. Ask whether the credit applies retroactively.
- Read the next renewal offer for the credit by name and for any change in the dwelling limit. If the credit is missing, send the documents again and ask for a reply in writing.
- Compare with other insurers at the same limits. Each company defines "new" and "updated" differently, and a house that has aged out at one may sit at the top of another's range. homeowners insurance discounts to ask about lists the other credits to check at the same time.
Key takeaways
- New-home credits are defined by each insurer's age bands, commonly 10 to 15 years, and they shrink as the house ages.
- Renovation credits go to documented roofs, plumbing, wiring and heating, not cosmetic work.
- Check the year built and the systems the insurer has on file, then send invoices and permits and ask for a re-rate.
- Renovation and additions raise the replacement cost, so update the dwelling limit; that increase offsets part of any credit.
- In hurricane states, building-code era and FORTIFIED features can matter more than age, so ask about wind credits for new construction.
