- Municipalities cannot prohibit ADUs but may adopt reasonable regulations regarding size, parking, and other dimensional standards
- Contact Keene Community Development for the city's specific ADU application requirements and any local dimensional standards
Building Code
Keene follows the NH State Building Code (RSA 155-A), which is based on the International Building Code (IBC) and International Residential Code (IRC). All construction must comply with the state building code.
