Key Zoning Facts
Claremont Zoning Overview
Claremont is a city of approximately 13,000 residents in Sullivan County, New Hampshire, and serves as the county seat. Located along the Sugar and Connecticut Rivers in the upper Connecticut River Valley, Claremont is one of New Hampshire's oldest cities and has a history rooted in textile manufacturing. Today, land use and development are regulated through the city's zoning ordinance, codified in the Claremont Municipal Code. The Planning Department administers zoning, permitting, and long-range planning.
A key aspect of New Hampshire land use law affecting Claremont is RSA 674:71 (enacted 2017), which requires all municipalities — including Claremont — to permit accessory dwelling units (ADUs) in any zone that allows single-family housing. The state mandates that cities allow at least one ADU per single-family lot, either by right or with a conditional use permit. Claremont may set local standards for ADU size, setbacks, and design, but cannot prohibit them outright in single-family zones. New Hampshire's State Building Code (based on the 2018 IBC/IRC) applies to all permitted construction.
Key Zoning Districts
Claremont's zoning establishes residential districts at varying densities, with R-1 requiring larger rural-scale lots (20,000 sq ft) and R-2 accommodating typical urban residential lots (10,000 sq ft). The Central Business (CB) district covers the historic downtown core with minimal setbacks, encouraging street-front development. Industrial zones along river corridors support the city's manufacturing heritage.
| District | Type | Min Lot Size | Front Setback | Side Setback | Rear Setback | Max Height |
|---|---|---|---|---|---|---|
| R-1 | Single-Family | 20,000 sq ft | 30 ft | 10 ft | 30 ft | 35 ft |
| R-2 | General Residential | 10,000 sq ft | 25 ft | 8 ft | 25 ft | 35 ft |
| R-3 | Multi-Family | 6,000 sq ft/unit | 20 ft | 10 ft | 20 ft | 40 ft |
| CB | Central Business | Varies | 0 ft | 0 ft | Varies | 45 ft |
ADU Rules
New Hampshire RSA 674:71 requires Claremont to permit at least one ADU per single-family lot in any residential zone that allows single-family housing. ADUs may be attached, detached, or internal (such as a basement apartment). The city may regulate dimensions and design standards but cannot outright prohibit them. Contact the Planning Department at (603) 542-7003 for current local ADU standards, parking requirements, and permit procedures.
Development Process
Development in Claremont requires permits through the Planning Department. The typical process includes:
- Zoning Verification — Confirm your proposed use is permitted in the applicable zoning district by contacting Planning or reviewing the municipal code
- Site Plan / Subdivision Review — Projects above certain thresholds require review by the Planning Board
- Building Permit — Apply for a building permit with construction documents complying with the NH State Building Code
- Inspections — Schedule required inspections during construction
- Certificate of Occupancy — Obtain final approval before occupying the structure
Nonconforming proposals may require a variance or special exception from the Zoning Board of Adjustment.
Key Considerations
Before starting any development project in Claremont, property owners should:
- Verify zoning classification by contacting Planning at (603) 542-7003
- Review the municipal code for district-specific standards
- Determine flood zone status using FEMA's Flood Map Service Center — properties near the Sugar River and Connecticut River may be in flood zones
- Understand that NH RSA 674:71 provides state-level ADU rights that Claremont must honor in single-family zones
- Contact the Planning Department for pre-application guidance
