The 2025 tax rate for Londonderry is $14.47 per 1,000. This is set annually in October by the Department of Revenue.

Per RSA 79, Timber Tax, an “intent to cut” application must be completed and submitted to the Assessing Department before any timber can be cut from any property. The application can be completed by the logger but must be signed by the owner, as the owner is the person responsible for the payment of the timber tax. There can be exceptions to a cut. The law allows for up to 15,000 board feet of logs, 30 cords of wood, or 300 tons of whole wood tree chips to yield tax-free per tax year, so long as the logs or wood is used for the personal use of the owner. The logs or wood cannot be sold or even given in place of payment for the timber cut; a yield tax would be issued if that were the case. For purposes of land conversion, for example, land developed for a house, an “intent to cut” is not required if less than 15,000 board feet or 30 cords of wood are cut. Applications are available at the Assessor’s office; contact us if you have any questions.

To find the value of any piece of property, the Assessor must first know what properties similar to it are selling for, what it would cost to replace it, how much it takes to operate and keep it in repair, what rent it may earn, and many other dollar facts affecting its value, such as the current rate of interest charged for borrowing the money to buy or build properties like yours. Using these facts, the Assessor can then go about finding the property value in three different ways.

Sales Comparison Approach

The first method compares your property to others that have recently sold. These prices, however, must be analyzed very carefully to get the true picture. One property may have sold for more than it is worth because the buyer was in a hurry and would pay any price. Another may have sold for less money than it was worth because the owner needed cash right away. The property was sold to the first person who made an offer. When using the sales comparison approach, the Assessor must always consider such overpricing or underpricing and analyze many sales to arrive at a fair valuation for your property. Size, quality, condition, location, and time of sale are also important factors to consider.

Cost Approach

A second way to value your property is based on how much money it would take, at current material and labor costs, to replace your property with one similar. If your property is not new, the Assessor must also estimate how much a lot like yours would be worth, if vacant.

Income Approach

The third way is to evaluate how much income your property would produce if it were rented as an apartment house, a store, or a factory. The Assessor must consider operating expenses, taxes, insurance, maintenance costs, and the return most people would expect on your kind of property.

Abatement forms are available in the Assessor’s office and on-line after the final tax notice (December tax bill) has been mailed. The last day to apply for an abatement is March 1st following the final tax bill.

The Town of Londonderry has had an ongoing Cyclical Inspection program since 2002. At this time, we have completed measuring and listing the entire town the first time through. During the beginning of 2009, we began remeasuring and listing all properties again in South Londonderry with Map 1. This program began again in 2016 and will take about 5 to 6 years to do for the whole town. This program is only to verify the information that we have on our property record card. Your value will change only if we find discrepancies.

April 15th is the deadline for all applications for exemptions and credits. See exemptions on our website for specifics, or call the Assessor’s office at 603-432-1100, ext. 190, for more information.

The tax year by State Law starts on April 1st and runs through March 31st (the next year). When you are building a structure, you are taxed on what is there on April 1st of any year. When you remove a structure (i.e., pool), if it is taken down after April 1st, you will be taxed until the next year.

The 2024 ratio for Londonderry is 85.3%. This is set by the Department of Revenue (DRA). At the end of each year, the Londonderry Assessing Department sends a report to the DRA of all arms-length sales data that occurred between October 1st and September 30th. The DRA compares the assessed value and the selling price to determine a ratio between the two. All sales between family members, sales within corporations, foreclosures, and fiduciary sales are not considered to be arms-length sales and are eliminated from the data. The DRA calculates an average and determines what each Town's ratio is for the previous year. The 2025 ratio will be available in the spring of 2026.

For building, health, and zoning regulations you may contact the phone number 603-432-1100, ext. 115, or email Christine Wholley, Permit Technician.

No, provided there is no structural work involved. If it is discovered that some portion of the building framing needs to be replaced because of moisture damage, then a permit and follow-up inspection would be required.

Yes. Provided the property is a single-family dwelling occupied by the owner as their primary domicile with no other living units in the structure, the owner may do their own work.

If the additional bedroom exceeds the total number of bedrooms for which the existing system was designed, then a new septic system must be designed for the property. The newly approved system is not required to be installed until such time when the existing system fails.

Residential stairways must be at least 36 inches wide with treads at 10 inches minimum depth and a maximum riser height of 7 and 3 / 4 inches. Handrails are required on any stairway with 4 or more risers (steps). Handrails must be installed at a height between 34 inches to 38 inches above the stair (measured at the stair nosing).

Yes. You can install a fence no more than 6 feet in height on your rear and side property lines. Any fence taller than 6 feet is considered a structure and must then meet the setback requirements. Fences along the front property line may not exceed 4 feet in height and should be of the "open" type such as chain-link, rail, or picket.

No. Provided that the sides of the pool are a solid structure (not the vinyl inflatable type) and the walls are at least 48 inches in height above the ground.

All structures in the Residential Agricultural (AR-1) zoning district are required to be setback from the property lines by the following distances:

• Front Property Line Setback: 40 feet
• Side and Rear Property Line Setback: 15 feet
• Structures and Enclosures for Housing Livestock: must be setback 25 feet

View or download the 2.3.1.7 Accessory Dwellings (PDF).

As of January 1, 2025, no permit is required for sheds under 400 square feet. Permits are still required for sheds over 400 square feet. A shed 400 square feet or more must have footings installed to frost depth of 48 inches. All sheds regardless of size must comply with all setback provisions.

Londonderry homeowners are responsible for their driveway culvert. In order for the culvert to remain clean at all times, we ask that residents periodically check their culvert and free it from debris. This will go a long way toward alleviating erosion, ice build-up and drainage problems in the future.

From November 1 to March 31, vehicles cannot park on the roadway between Midnight and 6 am.

For more information, view or download the Winter Parking Ban (PDF).

Location of Mailboxes

Mail and newspaper boxes are the only items allowed in the Town’s right-of-way. The following are suggestions for reducing the possibility of damage. The mailbox should be installed in such a manner that no part of the mailbox is within 3 feet from the edge of the pavement if there is no curbing, and 2 feet from the edge of the pavement if there is curbing. Installation should be sufficiently sturdy to withstand the weight of heavy snow resulting from plowing operations.

Generally, the Town has a 50-foot right-of-way, which extends 13 feet from the edge of the pavement. Residents are asked not to reconstruct road shoulders and swales or place any structures and landscape items within the Town Right-of-Way. Stakes, delineators, or rocks create a road hazard and should be removed. The Town is not liable for damages that may occur to objects placed within its right-of-way.

If you do not own the property, you must obtain written permission from the property owner in order for a permit to be issued. Burning is allowed from 5 pm to 9 am or while raining. A fire permit is not required anytime there is a 100-foot radius of complete snow cover around the fire. All fires must be attended at all times by the permit holder. During windy or dry weather, times of drought, or high fire danger, burning permits will not be issued and all burning is prohibited. Also, see our Outdoor Fire Permit Rules.

Today's new homes require by code a hardwired detector on each floor in addition to a detector in each bedroom. Older Homes do still need at least one smoke detector on each floor, including the basement. For maximum protection in these occupancies, we highly recommend one in each bedroom too. If you are renting a property, the landlord is required to have hardwired smoke detectors throughout the unit.

First, contact your landlord or property manager and request that it be looked at immediately. If there is a delay in the repairs or if you need further assistance, please call the Fire Prevention Office at 603-432-1124 and we will assist you.

You should test your smoke detector monthly. Most detectors have a button you can push to test them. Change the batteries in your smoke detector twice a year. A handy way to remember to change your batteries is to do it when you change your clocks for daylight savings time. Smoke detectors should be replaced at least every ten years. Never disable your smoke detector by removing the batteries. Remember, a smoke detector that isn't working cannot save you.
