     45-23-44. General provisions — Physical design requirements.

     (a) All local regulations shall specify, through reasonable, objective standards and criteria,

all physical design requirements for subdivisions and land-development projects that are to be

reviewed and approved pursuant to the regulations. Regulations shall specify all requirements and

policies for subdivisions and land-development projects that are not contained in the municipality’s

zoning ordinance.

     (b) Nothing in this section shall be construed to restrict a municipality’s right, within state

and local regulations, to establish its own minimum lot size per zoning district in its town or city,

except subject to subsection (g) of this section.

     (c) The slope of land shall not be excluded from the calculation of the buildable lot area or

the minimum lot size, or in the calculation of the number of buildable lots or units.

     (d) Wetland buffers, as defined in § 2-1-20, shall be included in the calculation of a

minimum lot area and in the total number of square feet or acres of a tract or parcel of land before

calculating the maximum potential number of units or lots for development; provided, however,

that this shall not apply to lots directly abutting surface reservoirs with direct withdrawals used for

public drinking water. Nothing herein changes the definition and applicability of a “buildable lot”

as set forth under § 45-23-60(a)(4); and nothing herein permits the disturbance of wetlands or

wetland buffers or otherwise alters the provisions of the freshwater wetlands act, § 2-1-18 et seq.

     (e) The requirements and policies may include, but are not limited to: requirements and

policies for rights-of-way, open space, landscaping, connections of proposed streets and drainage

systems with those of the surrounding neighborhood; public access through property to adjacent

public property; and the relationship of proposed developments to natural and man-made features

of the surrounding neighborhood.

     (f) The regulations shall specify all necessary findings, formulas for calculations, and

procedures for meeting the requirements and policies. These requirements and policies apply to all

subdivisions and land development projects reviewed and/or administered under the local

regulations.

     (g) Local regulations shall be modified as needed to meet the purposes of § 45-24-78

concerning attached single-family dwellings including, but not limited to, updated physical design

requirements concerning minimum lot size, lot width, lot frontage, lot depth requirements, setbacks

and street access.

     (1) In a land development project consisting of attached single-family dwellings, individual

lots shall not be required to provide permanent physical access to a public street, regardless of lot

frontage; provided that, the development as a whole, shall provide adequate permanent physical

access to a public street consistent with local regulations.

ordinance may provide for a procedure under which a proposed land use that is not specifically

listed may be presented by the property owner to the zoning board of review or to a local official

or agency charged with administration and enforcement of the ordinance for an evaluation and

determination of whether the proposed use is of a similar type, character, and intensity as a listed

permitted use. Upon such determination, the proposed use may be considered to be a permitted use.

     (b) Notwithstanding any other provision of this chapter, the following uses are permitted

uses within all residential zoning use districts of a municipality and all industrial and commercial

zoning use districts except where residential use is prohibited for public health or safety reasons:

or homes, as the need may be, elsewhere upon the land, for use and occupancy of the former

occupants for a period of up to twelve (12) months, or until the building or structure is rehabilitated

and otherwise made fit for occupancy. The property owner, or a properly designated agent of the

owner, is only allowed to cause the mobile and manufactured home, or homes, to remain

temporarily upon the land by making timely application to the local building official for the

purposes of obtaining the necessary permits to repair or rebuild the structure.

shall be a permitted use and allowed by specific and objective provisions of a zoning ordinance,

except where such is prohibited by environmental land use restrictions recorded on the property by

the state of Rhode Island department of environmental management or the United States

Environmental Protection Agency preventing the conversion to residential use.

     (1) The specific zoning ordinance provisions for adaptive reuse shall exempt adaptive reuse

developments from off-street parking requirements of over one space per dwelling unit.

private water, such as a well and and/or wastewater treatment system(s) approved by the relevant

state agency for the entire development as applicable.

     (ii) For all other adaptive reuse projects, the residential density permitted in the converted

structure shall be the maximum allowed that otherwise meets all standards of minimum housing

and has access to public sewer and water service or has access to adequate private water, such as a

well, and wastewater treatment system(s) approved by the relevant state agency for the entire

development, as applicable. The density proposed shall be determined to meet all public health and

safety standards.

     (3) Notwithstanding any other provisions of this chapter, for adaptive reuse projects,

existing building setbacks shall remain and shall be considered legal nonconforming, but no

additional encroachments shall be permitted into any nonconforming setback, unless otherwise

allowed by zoning ordinance or relief is granted by the applicable authority.

the height exemption.

     (i) Notwithstanding any other provisions of this chapter, all towns and cities may allow

manufactured homes that comply with § 23-27.3-109.1.3 as a type of single-family home on any

lot zoned for single-family use. Such home shall comply with all dimensional requirements of a

single-family home in the district or seek relief for the same under the provisions of this chapter.

     (j) Notwithstanding any other provision of this chapter, an attached single-family dwelling

that meets the requirements of § 45-24-78 shall be a permitted use in all residential zoning districts

according to the conditions set forth therein.

     (1) Each city or town shall amend its zoning ordinances to conform to subsection (j) of this

section within six (6) months of the department of housing publishing model ordinance language

pursuant to § 45-24-78(b). In the event that a city or town fails to timely amend its zoning

ordinances, attached single-family dwellings shall be permitted in the residential zoning districts

of the city or town according to the terms of the model ordinance language.

     SECTION 3. Chapter 45-24 of the General Laws entitled "Zoning Ordinances" is hereby

amended by adding thereto the following section:

     45-24-78. Attached single-family dwellings.

     (a) Pursuant to § 45-24-37, attached single-family dwellings shall be allowed by right in

residential zoning districts under the following circumstances:

     (1) The parcel to be developed has access to public sewer and water service or has access

to adequate private water, such as a well and/or wastewater treatment system(s) approved by the

relevant state agency.

     (2) The residential density of the development does not exceed the greater of:

     (i) The maximum density permitted by the comprehensive plan of the city or town for the

area in which the parcel is located, irrespective of zoned density; or

     (ii) The total number of units permitted to be developed on the parcel by local ordinance.

If the foregoing criteria are satisfied, each attached single-family dwelling shall be entitled to its

own parcel through subdivision regardless of any base zone standards concerning minimum lot

size, lot width, lot frontage, or lot depth.

     (3) Any base zone standards concerning setbacks shall apply relative to the external

boundary of a row of attached single-family dwellings rather than to each individual parcel. Any

standards concerning permeable surface or lot building coverage shall apply to individual parcels

in the form of a percentage, calculated according to what the base zone permits by right for detached

single-family dwellings. All other dimensional standards of the base zone shall apply.

     (4) Cities and towns may establish additional development standards for attached single-

LC001475 - Page 13 of 15

family dwellings in local ordinance; provided that, such standards shall not restrict a dwelling to

less than three (3) stories, restrict its floor area ratio to less than one, or require more than one off-

street parking space. The off-street parking, lot access, or other amenities for an attached single-

family dwelling may be provided off-site through a homeowners’ association or other form of

common ownership arrangement.

     (b) To alleviate administrative burdens for cities and towns, the department of housing

shall issue a guidance document setting forth model ordinance language on attached single-family

dwellings within three (3) months from the effective date of this section.

     (c) An attached single-family dwelling authorized under this section shall be considered to

have satisfied the positive findings required under § 45-23-60(a)(1) and (a)(3).

     SECTION 4. This act shall take effect upon passage.
