ADUs – What Are They?

 Early 20th century – a common feature in SF homes  A second, smaller dwelling on the same grounds as

a single-family house – attached or detached

 An apartment over the garage, in the basement, in an

  • utbuilding

 Also called granny flats, in-law apartments, family apartments,

  • r secondary units

 With post-WWII suburbanization and deployment

  • f “Euclidean” zoning, ADUs became far less

prevalent

 Baby boom | Car boom | Sprawl  Less interest in efficient use of space

Benefits of ADUs

 Increases a community’s housing supply without

further land development

 Facilitates efficient use of existing housing stock &

infrastructure

 An affordable housing option for many low- and

moderate-income residents

 Improves homeowner cash flow  Helpful to elderly and/or disabled people who may

want to live close to family members

 or caregivers, empty nesters, young adults, etc.

Background to SB 146

 NH Center for Public Policy Studies 2014 reports:

“Housing Needs and Preferences in New Hampshire”

 Slower population growth; aging population  Mismatch of housing stock and needs and desires of

changing population-young and old

 Older adults want to “age in place” or “age in

community”

 Homebuilders unable to fulfill homeowner requests

to create ADUs for a family member or caregiver

 Stymied by local land use restrictions

SB 146 – The Basics

 Defined: independent living unit (sleeping, cooking,

eating, sanitation)

 Adequate water supply and sewage disposal required  Interior door between primary unit and ADU required  Municipalities must allow an attached ADU in any single-

family zone by right, special exception, or conditional use permit

 If the zoning ordinance is silent on ADUs, then they are

allowed in any single-family home (regardless of zone)

 Standards for a single-family home also apply to

combined SF and ADU (e.g., setbacks and frontage)

slide-11
SLIDE 11

SB 146 – Options

 Municipality may

 Require adequate parking to accommodate an ADU  Require owner occupancy of one of the units (but can’t

say which one)

 Require demonstration that a unit is the owner’s primary

dwelling unit

 Control for architectural appearance (“look and feel”)  Limit the number of ADUs per single family dwelling  Limit the number of unrelated individuals that occupy a

single unit (concern of college towns)

slide-12
SLIDE 12

SB 146 – Prohibitions

 Municipality must not

 Limit ADU to 1 bedroom or to be less than 750 s.f.  Require familial relationship between occupants of

principal dwelling and ADU

 Require additional lot area or other dimensional

standards for ADU (but it may increase lot size for a detached ADU)

 Require door between primary unit and ADU to remain

unlocked

slide-13
SLIDE 13

 Other elements

 Detached ADUs

 Municipalities may allow at their discretion  A municipality may require increased lot size, but other

statutory standards for attached ADUs will apply

 Amends NH RSA 674:21 Innovative Land Use Controls

 ADUs are removed from list along with its definition – no

longer a voluntary land use regulation

Next Steps

 SB 146 signed by Governor Hassan on March 16  Effective date: June 1, 2017  Educate municipalities about the new ADU law and

how to meet its requirements

 Create training materials and other resources  Work with partners

 Plan NH  NH Municipal Association  Office of Energy and Planning  BIA  Regional Planning Commissions  Workforce Housing Coalitions  NH Homebuilders Association  You!
