Cheshire County, New Hampshire has no county zoning or building department: each of the county's towns handles building permits and zoning on its own1. New Hampshire's state building code still requires a permit before most new construction, regardless of whether a given town runs its own building office2. This guide uses Keene — the county seat and Cheshire County's largest city — as a worked example of how a town-level building and planning office works; contact your own town's office for its specific rules and fees3.

Do you need a building permit in Cheshire County, New Hampshire?
Cheshire County has no county building department, but a building permit is still required almost everywhere in New Hampshire before new construction begins: state law puts a duty on the person responsible for construction to obtain a permit before starting covered work210. Most Cheshire County towns enforce that requirement locally, through their own building or code office, following whatever process that town has adopted10. In a town that has not adopted its own enforcement mechanism, the state fire marshal runs a state building permit system instead, though that state-run system does not cover an ordinary one- or two-family home; ask your town clerk who currently issues residential permits if your town has no building office10. Keene, the county seat and Cheshire County's largest city, is a worked example: its Building Safety staff reviews, approves, issues and inspects all construction in the city, including structural, electrical, plumbing, mechanical, accessibility, energy-efficiency and floodplain-development work3.
Who handles building permits and zoning in Cheshire County, since the county doesn't?
Cheshire County itself runs no zoning, planning or building department; its own list of county departments covers things like the sheriff, registry of deeds, corrections and human services, not land use1. Zoning and building permits are a municipal function everywhere in New Hampshire, so the office you need depends entirely on which of Cheshire County's towns your land sits in1. In Keene, that office is the Community Development Department, which runs both Building Safety and Planning & Zoning out of one office, reachable by phone or email311. If your land is in one of the county's smaller towns, start with that town's own town hall or select board office instead of Keene's, since each town sets and enforces its own rules1.
Does Cheshire County have zoning?
No: Cheshire County has no zoning ordinance and no planning department, and it exercises no zoning authority over any land in the county1. Zoning in New Hampshire is set town by town, and a town's planning board only regulates subdivision of land if that town has specifically authorized the planning board to do so by ordinance or resolution12. Even a farm or ranch building is not automatically exempt from a town's dimensional standards, setbacks, driveway rules or similar requirements; New Hampshire law lets a local board grant a waiver for an agricultural use only after notice and a hearing, and only to the extent needed to reasonably permit that use13. Because rules genuinely differ from one Cheshire County town to the next, confirm your specific parcel's zoning district and any subdivision requirements with that town's own office, such as Keene's Planning & Zoning staff for property inside the city11.
How do septic permits work in Cheshire County?
Septic permits in Cheshire County go through the state, not the county or even the town: the New Hampshire Department of Environmental Services requires prior approval of plans before anyone builds a structure that will discharge sewage or constructs a septic system414. You need both an approval for construction and an approval for operation before you can use a new system, and locally approved plans must also be submitted where a town planning board or other local body requires them1516. Soil is a real constraint here: only 10.9% of Cheshire County's soil rates free of severe limits for a conventional septic drain field in the USDA's survey, so budget for a site evaluation and the possibility of an engineered system on much of the county's land7. If a public sewer is within 100 feet of your building, state law requires connecting to it instead of using a septic system17.
Can you live in an RV or tiny home on your land in Cheshire County?
New Hampshire's recreational-campground law governs RVs at licensed, regulated campgrounds and camping parks, where a site is for temporary recreational occupancy only, not year-round residency, unless that site meets the same construction standards as a single-family house6. Outside a licensed campground, the same law lets a landowner host an RV on their own parcel for occasional use of no more than 7 days in a calendar year, but only after filing a statement of compliance with the town's governing body within 7 days before that use6. Neither provision creates a general right to live in an RV on ordinary land year-round; that question depends on your specific town's zoning ordinance, so confirm it with your town's planning or zoning office before you buy1. A composting or incinerator toilet needs no state sign-off if the structure has no internal plumbing and no supplied water service, which is worth knowing if you are building a simple cabin without a well or septic system18.
Building a home in Cheshire County: the steps, in order
- Contact your specific town's building or code office (or the Community Development Department if you're in Keene) to confirm local zoning, setbacks and the permit process before you design11.
- If your lot needs a septic system, get your design approved by the New Hampshire Department of Environmental Services and obtain a construction approval before building starts1514.
- Apply for your building permit through your town's building office if it has adopted its own enforcement mechanism; otherwise check with your town clerk about the state fire marshal's building permit system10.
- Build to the state building code and request the required inspections as work proceeds, including before any work is concealed19.
- Get your septic system's approval for operation from NHDES before you use it, in addition to the earlier construction approval15.
- Close out with a certificate of occupancy where your town requires one, after final inspections confirm the work meets state and local codes20.
What to check before you buy land in Cheshire County
Confirm which town your parcel sits in and call that town's office directly, since Cheshire County itself sets none of the zoning, building or subdivision rules that will govern your land1. Test the soil before you count on a simple septic system: with only 10.9% of the county's soil rated free of severe limits for a conventional drain field, many lots will need an engineered system and a New Hampshire Department of Environmental Services site evaluation7. If you plan to drill a well, know that the contractor must file a completion record with the state within 90 days, so ask for a copy for your own records21. Property taxes run well above the national norm here: the effective rate is about 2.3% of assessed value, producing a typical annual bill near $5,968, so factor that into any purchase822. Homeowners insurance is comparatively affordable, with a typical policy near $1,375 a year23.
Watch-outs
- Cheshire County has no zoning, building or planning department of its own; every rule that matters for your land is set by the specific town it sits in, so confirm directly with that town before you buy1.
- New Hampshire's occasional-RV-use exception is capped at 7 days a year and requires filing a statement of compliance with the town in advance; it is not a path to living on raw land in an RV6.
- This guide could not confirm an owner-builder exemption at the county level; ask your specific town's building office whether it allows a homeowner to act as their own contractor5.
