What it takes to build here — permits, zoning, and septic — scouted from Sullivan County’s own official sources.
NH has no county building department; under RSA 155-A permits are required by statute but issuance and enforcement are reserved to individual towns/cities, and many rural Sullivan County towns have no local building official, so permit requirements vary by town.
NH RSA Chapter 155-A (New Hampshire Building Code) ↗Zoning in New Hampshire is a municipal power granted to towns and cities under RSA 674:16-18; Sullivan County itself does not zone, but individual towns adopt and enforce their own zoning ordinances.
NH RSA Chapter 674 (Local Land Use Planning and Regulatory Powers) ↗Subsurface/septic systems are permitted by the state: NHDES reviews design plans and issues the Approval for Septic System Construction and Approval for Operation, with designs prepared by a state-permitted designer (RSA 485-A).
