Building permits, zoning and septic rules in Franklin County, Massachusetts
67Index Score / 100 #1 of 14 in Massachusetts
Franklin County, Massachusetts has no county government at all, so there is no county building department, zoning office or septic authority to call1. A building permit is required everywhere in the county under the statewide Massachusetts building code, but it is issued and enforced by each of the county's individual towns, not by the county1. Zoning is likewise adopted and enforced town by town under the state Zoning Act2, and septic systems statewide follow the Title 5 code (310 CMR 15.000) with permits issued by each town's Board of Health3. This guide uses Greenfield, the county's traditional county seat and largest city, as a worked example of what one Franklin County town requires; your own town's offices will differ.

Do you need a building permit in Franklin County, Massachusetts?
Yes, a building permit is required everywhere in Franklin County under the statewide Massachusetts building code (780 CMR), but there is no county-level office that issues it — Franklin County has no county government, so permits are issued and enforced by each individual town's building inspector1. In Greenfield, the county's largest city and traditional county seat, the Building Inspections Department administers state building, electrical, plumbing and gas codes and enforces the city's own zoning ordinance on top of them9. If you buy land in a different Franklin County town, expect a similar process at that town's own building department rather than Greenfield's. Many smaller towns share inspectors: the Franklin County Cooperative Inspection Program provides state-mandated building, electrical and plumbing/gas inspection services, or a subset of them, to 18 Franklin County towns10. Homeowners get one statewide break: an owner may apply for a permit on their own primary residence under a homeowner exemption in the building code, without needing a licensed construction supervisor, though a contractor cannot use this exemption5.
Who issues building permits in Franklin County, and how do you reach them?
Because Franklin County has no county government, there is no single county building department to call1. Greenfield's Building Inspections Department is one working example: it is reachable at 413-772-1404, and permit applications can be mailed to City Hall at 14 Court Square or dropped off at the department's office at 20 Sanderson Street9. Zoning applications and land-use permit questions in Greenfield go to the separate Planning & Development Department, which assists applicants with land use permits and the municipal boards and commissions that review them11. Every one of Franklin County's other towns has its own equivalent offices or shares inspection services through the Franklin County Cooperative Inspection Program, which also handles zoning enforcement in 16 towns12. Confirm the right town before you call, since Greenfield's numbers only apply inside Greenfield; septic permits stay with each town's Board of Health either way.
Does Franklin County have zoning?
Franklin County itself has no zoning power because it has no county government; Massachusetts cities and towns adopt the zoning ordinances and bylaws that regulate land, buildings and structures24. The zoning district, allowed uses, dimensional controls and enforcement authority therefore vary by municipality across Franklin County4. In Greenfield, the Planning & Development Department administers the city's own zoning ordinance and helps applicants with land-use permits11. Local zoning cannot regulate the interior area of a single-family home6. A single accessory dwelling unit is allowed by right in a single-family zoning district, subject to reasonable local rules and a maximum area of the lesser of half the main home's floor area or 900 square feet7. A town may also restrict or prohibit short-term rental of an accessory dwelling unit8.
How do septic permits work in Franklin County?
Septic systems throughout Franklin County follow the statewide Title 5 code (310 CMR 15.000), but the permit itself is issued and enforced locally by each town's own Board of Health rather than by any county or state office3. In Greenfield, the Health Department reviews and assesses septic systems and coordinates with the DPW on safe sewer and water supplies13. Under Massachusetts law the local board of health must act on a completed septic application within 45 days, and a complete application includes deep observation holes and percolation test results14. Soil is the practical constraint here: only about 1.4% of Franklin County's soils are rated without severe limits for a conventional septic drain field in USDA's survey, so plan on a percolation test and a real chance you will need an engineered, mound or other alternative Title 5 system rather than a standard gravity field153. One narrow statewide rule can override a septic plan: if your parcel abuts a street where the town has already installed both a public drain and a public sewer, state law requires you to connect your plumbing to that sewer instead of using a septic system — this does not create a general rule requiring a sewer connection on land with no public sewer nearby16.
Can you live in an RV or tiny home on your land in Franklin County?
The applicable zoning rules for an RV or tiny house vary by Franklin County municipality, including local districts and dimensional controls4. We could not confirm a Franklin County-wide rule for long-term RV occupancy, temporary camping or tiny-home occupancy, so ask the planning or zoning office in the town where the parcel lies. The statewide seasonal-community tiny-house provision is conditional on local adoption and does not by itself establish permission on a Franklin County parcel17. Massachusetts does allow an owner whose residence was destroyed by fire or another natural disaster to place and occupy a manufactured home on that site for up to 12 months while rebuilding, subject to the state sanitary code18. If the proposed tiny home is an accessory dwelling unit, a town may restrict or prohibit its use as a short-term rental8.
Building a home in Franklin County: the steps, in order
Identify which Franklin County town your land is in, since building, zoning and septic rules are set entirely by that town, not by the county2.
Contact that town's planning or zoning office for a preliminary consultation before you design anything; in Greenfield this is the Planning & Development Department11.
Have your soil tested for septic suitability early — under 1.4% of Franklin County's soils are free of severe limits for a conventional drain field, so many properties need an engineered or alternative Title 5 system153.
Apply for your septic (Title 5) permit through your town's Board of Health, such as Greenfield's Health Department13.
Apply for your building permit through your town's building inspector once septic and zoning approvals are in hand; in Greenfield that is the Building Inspections Department9.
If you are the homeowner, ask about the owner-builder homeowner exemption, which lets you pull your own permit without a licensed construction supervisor for your primary residence5.
Schedule required inspections during construction and apply for an occupancy permit from the building inspector once work is complete.
What to check before you buy land in Franklin County
Soils and septic are the biggest practical constraint: fewer than 1.4% of Franklin County's soils are rated free of severe limits for a conventional drain field, so get a percolation test before you commit to a price15. The county is heavily wooded and mostly gentle, with about 86.6% forest cover and 62.1% of land at 15% slope or less1920. It gets about 49.1 inches of precipitation a year and sits in severe drought in roughly 5% of years2122. The nearest city of 100,000 or more people is about 28 miles away in straight-line distance23. Home values run high for a rural county, with typical homes around $379,656 and farmland averaging about $8,637 an acre2425. Budget for property taxes too: the effective rate runs about 1.5%, with a median annual bill around $4,595, and typical homeowners insurance runs about $1,435 a year262728. If you plan to farm or homestead commercially, Massachusetts's statewide agricultural-use protection can shield qualifying farm land and structures from unreasonable local zoning restriction, subject to minimum parcel size and sales thresholds29.
Watch-outs
Franklin County has no county government, so nothing here about Greenfield's offices, phone numbers or fees applies in any other Franklin County town; confirm the right town before you call1.
Under 1.4% of Franklin County's soils are rated free of severe limits for a conventional septic drain field, so a percolation test before you buy is not optional in most of the county15.
The state's tiny-house allowance for undersized lots only applies in municipalities designated "seasonal communities," and no Franklin County town is on that list, so it does not create a tiny-home right here17.

Construction, maintenance, or alteration of individual sewage disposal systems for residential buildings of not more than four dwelling units in Franklin County.
The permitting authority is the applicable city, town, or district health officer or board of health.
A completed application includes information satisfactory to the local board of health, including deep observation holes, percolation test results, and a plan meeting state sanitary code and local health regulations.
The applicant remains subject to regulations promulgated under Massachusetts General Laws chapter 21A, section 13.
permit decision deadline: <= 45 days (If no determination is rendered within 45 days, the permit is deemed granted.)
“shall act upon a completed application for such permit to construct, maintain, or alter such system within forty-five days”
Building permitRequired
A building permit is required under the statewide Massachusetts State Building Code (780 CMR), enforced by MUNICIPAL building inspectors appointed under MGL Ch. 143; Franklin County has no county government, so permits are issued at the town level, not by any county.
Zoning in Massachusetts is adopted and enforced at the MUNICIPAL (town) level under the Zoning Act (MGL Ch. 40A); Franklin County has no county government, so zoning is purely town-level.
Persons building their own home or personally doing renovations, regarding registration under Massachusetts home-improvement-contractor law, Chapter 142A.
This is an exemption from registration under Chapter 142A; it does not establish an exemption from building permits, inspections, certificates of occupancy, or other applicable licensing requirements.
The cited statutory provision contains additional exemptions and conditions for other categories of persons.
“The following persons are not required to be registered under this chapter: [...] persons building their own home or personally doing the renovations;”
Building code adoptedAdopted
The Massachusetts state building code applies to all buildings and structures within every Massachusetts city and town, subject to the statutory exceptions and historic-district conflict rule stated in the official source.
Local inspectors enforce the state building code within the city or town from which they are appointed.
A statute, ordinance, or bylaw regulating exterior architectural features within an historic district, regional historic district, or architecturally controlled district prevails in the event of a conflict with the code.
The Section 3A exception applies to bridges and appurtenant supporting structures constructed by or under the custody and control of the department of highways or the Massachusetts Department of Transportation, or for which that department or authority has maintenance responsibility.
Section 94 separately lists bridge and appurtenant supporting-structure exceptions involving the department of highways, Massachusetts Department of Transportation, Massachusetts Bay Transportation Authority, metropolitan district commission, or Massachusetts Port Authority, or structures for which those agencies have maintenance responsibility.
“Unless otherwise provided by the state building code, the local inspector shall enforce the state building code as to any building or structure within the city or town from which he is appointed, including any building or structure owned by any authority established by the general court but not owned in whole or in part by the commonwealth, and the state building code shall be the code for all buildings and structures within the city or town.”
One more reviewed finding on this topic
Adopted — The Massachusetts state building code applicable to buildings and structures in Franklin County municipalities.
“the state building code shall be the code for all buildings and structures within the city or town.”
Minimum dwelling sizeNone
Local zoning ordinances and bylaws statewide, as to the interior area of a single-family residential building.
This finding concerns zoning regulation; state building-code requirements are not eliminated.
The cited statute separately permits reasonable bulk and height, yard-size, lot-area, setback, open-space, parking, and building-coverage regulations for land or structures used for specified religious or educational purposes.
“No zoning ordinance or by-law shall regulate or restrict the interior area of a single family residential building”

A movable tiny house must be registered with the Registry of Motor Vehicles, as applicable.
The municipality must be in a designated seasonal community; the statute requires designation for municipalities in Dukes and Nantucket counties and specified municipalities in Barnstable and Berkshire counties, and permits additional designations.
maximum floor area: <= 400 square feet excluding lofts · minimum year-round occupancy period: >= 10 months per year (The statute defines year-round housing as principal-residence occupancy for not less than 10 months a year.)
“A seasonal community shall: [...] adopt by-laws to permit the construction of tiny houses provided that such tiny houses are designated for use as year-round housing units”

Accessory dwellingsAllowed (with conditions)
A single accessory dwelling unit, or its rental, on the same lot as a principal dwelling in a Massachusetts single-family residential zoning district, including Franklin County municipalities.
The protection applies to a single accessory dwelling unit in a single-family residential zoning district.
The unit must be self-contained with sleeping, cooking, and sanitary facilities on the same lot as a principal dwelling.
The unit must maintain a separate entrance, either directly outside or through an entry hall or corridor shared with the principal dwelling sufficient to meet state building-code safe-egress requirements.
The unit may not exceed one-half of the principal dwelling's gross floor area or 900 square feet, whichever is smaller.
Otherwise applicable dimensional and parking requirements continue to apply.
Municipalities may impose reasonable regulations, including applicable 310 CMR 15.000 requirements, site plan review, dimensional setbacks, bulk and height regulations, and restrictions or prohibitions on short-term rental.
The use does not require owner occupancy of either the accessory dwelling unit or the principal dwelling.
A municipality may require no more than one additional parking space, and may require no additional parking space for an accessory dwelling unit located not more than 0.5 miles from a commuter rail station, subway station, ferry terminal, or bus station.
More than one accessory dwelling unit, or its rental, in a single-family residential zoning district requires a special permit.
Municipal zoning ordinances and by-laws remain the local implementation authority.
maximum gross floor area: 1/2 of principal dwelling gross floor area or 900 square feet, whichever is smaller · additional parking spaces: <= 1 space maximum (No additional parking space may be required when the ADU is located not more than 0.5 miles from a commuter rail station, subway station, ferry terminal, or bus station.)

“Boards of health may make reasonable health regulations.”
Off-grid sanitationLimited
Alternative or off-grid sewage handling on parcels abutting a public sewer in a Massachusetts town.
When a town has provided both a drain and a sewer in a public way, sewage must be connected to the sewer as directed by the responsible sewer authority.
This claim does not establish a statewide rule for parcels without access to a public sewer.
“When a town has provided both a drain for waters and a sewer for sewage in a public way, the owner of every parcel of land abutting on such way or connected with such drain or sewer shall arrange his plumbing so that the waters shall be kept separate from the sewage; and shall make such connections with the drain and sewer respectively that the waters shall pass into the drain and the sewage into the sewer in accordance with the directions of the board or officer having charge of the repair and maintenance of sewers in such town.”
Well permitLimited
Private-well digging or drilling in Massachusetts.
Massachusetts requires certification for persons engaged in the business of digging or drilling wells.
A city or town may require the person engaged in digging or drilling a private well to obtain a local site permit.
The local site permit may include terms and conditions ensuring health and safety and may carry a reasonable locally determined fee.
A completion report must be submitted to the Department within 30 days after completion of any well.
well completion report deadline: 30 days (After completion of any well by digging or drilling.)
“Said certification shall be sufficient authority for any said person to engage in the business of digging or drilling wells anywhere within the commonwealth and no further licensing or certification shall be required; provided, however, that nothing contained herein shall prohibit the appropriate local authority in any city or town from requiring any person engaged in the digging or drilling of private wells to obtain a site permit in accordance with terms and conditions which ensure health and safety and said city or town may charge said person a reasonable fee for said site permit as determined by the city or town.”
Mandatory utility hookupConditional
Sewer extensions and connections to sewer systems in Massachusetts, subject to state permitting and applicable municipal or sewer-district rules.
A currently valid permit issued by the director is required unless exempted by regulation.
Cities, towns, and sewer districts may prescribe rules for sewer connections, construction, alteration, use, and inspection of connection materials.
Local sewer rules must be published as specified by law and do not take effect until publication.
For additional connections in a final area of concern after commencement of sewer-system operations, the connection is subject to available capacity and, generally, board-of-health certification regarding compliance with 310 CMR 15.000 et seq.; certain public-service uses may be permitted subject to capacity.
Civil penalties for violation of applicable city, town, or sewer-district sewer rules may not exceed $5,000 per day.
maximum civil penalty for violation of local sewer rules: <= 5000 USD per day
“No person shall engage in any other activity that may reasonably be expected to result, directly or indirectly, in discharge of pollutants into waters of the commonwealth, nor construct, effect, maintain, modify or use any sewer extension or connection, without a currently valid permit issued by the director, unless exempted by regulation of the director.”
Agricultural exemptionAvailable (with conditions)
Commercial agriculture, aquaculture, silviculture, horticulture, floriculture, and viticulture land uses and related structures under Massachusetts local zoning law.
The statutory protection applies when, during June, July, August, and September or during the harvest season of the primary crop, 25 percent of products for sale based on gross sales dollars or volume were produced by the owner or lessee on the parcel; alternatively, 25 percent were produced on the parcel and at least an additional 50 percent were produced in Massachusetts on other qualifying land.
Activities may be limited to parcels of 5 acres or more, or to parcels of 2 acres or more in areas not zoned for the listed agricultural uses when annual sales generated from the use are at least $1,000 per acre based on gross sales dollars.
Land divided by a public or private way or waterway is construed as one parcel for this section.
The exemption does not exempt land or structures from floodplain or wetlands regulations established under the General Laws.
Agriculture has the meaning given in Chapter 128, Section 1A; horticulture includes growing and keeping nursery stock and its sale.
Agriculture, aquaculture, floriculture, and horticulture do not include marijuana-related growing, cultivation, distribution, or dispensation as described in the cited statutes, although a municipality may allow commercial marijuana growing and cultivation by zoning on land used for commercial agriculture, aquaculture, floriculture, or horticulture.
on-parcel production threshold: >= 25 percent (During June, July, August, September, or the primary crop’s harvest season; measured by gross sales dollars or volume.) · additional Massachusetts production threshold: >= 50 percent (Alternative test requiring at least 25 percent on-parcel production and additional production elsewhere in Massachusetts.) · minimum parcel size: >= 5 acres (Activities may be limited to parcels of 5 acres or more.) · alternative minimum parcel size: >= 2 acres (In areas not zoned for the listed agricultural uses, only if annual sales are at least $1,000 per acre based on gross sales dollars.) · annual sales threshold: >= 1000 USD per acre (Applies to the 2-acre alternative in areas not zoned for the listed agricultural uses.)
“nor shall any such ordinance or by-law prohibit, unreasonably regulate, or require a special permit for the use of land”
Subdividing landRegulated (with conditions)
Subdivision of land in Massachusetts cities or towns where the subdivision control law is in effect.
A proposed subdivision plan must be submitted to the applicable city or town planning board for approval before subdivision.
The plan must show the lots and existing or proposed ways furnishing access to the lots.
After approval, changes to the location or width of ways require amendment under section 81W.
Lot changes must retain required frontage under local ordinance or by-law, or at least 20 feet if no such frontage distance is required.
minimum frontage when no local distance is required: 20 feet (Applies to changed lots after approval under § 81O.)
“No person shall make a subdivision of any land in any city or town in which the subdivision control law is in effect”
Short-term rentalsLimited
Short-term rental restrictions applicable to accessory dwelling units in Massachusetts, including Franklin County municipalities.
Municipalities may impose restrictions or prohibitions on short-term rental of an accessory dwelling unit.
This claim is limited to short-term rental of accessory dwelling units; it does not establish a countywide rule for all short-term rentals.
“is subject to such additional restrictions as may be imposed by a municipality, including, but not limited to, additional size restrictions and restrictions or prohibitions on short-term rental, as defined in section 1 of chapter 64G”
Campground & park staysLimited
Temporary camping at public recreational facilities operated in Massachusetts state parks, state forest recreation areas, and state reservations.
Camping is limited to areas operated as public recreational facilities by the commissioner; the statute does not authorize camping generally on all Massachusetts land.
Facilities must be consistent with the policy of the Commonwealth as set forth in section 2B.
The commissioner may impose and collect charges and fees for use of the lands, buildings, facilities, and equipment, and may revise those fees from time to time.
A disabled veteran, Purple Heart recipient, or handicapped person whose vehicle bears the specified distinctive type number plate is not required to pay charges or fees imposed under section 2D(2).
“In the development and improvement of state parks, state forest recreation areas and state reservations, the commissioner is hereby authorized and empowered:—(1) To acquire, plan, construct, maintain and operate public recreational facilities, including roads, areas for parking, picknicking and camping, provisions for swimming, wading, boating, outdoor games, winter sports, horseback riding, bicycling and hiking trails, nature study, rest areas, outlooks, comfort stations, food accommodations and such other facilities as the commissioner deems necessary and desirable and consistent with the policy of the commonwealth, as set forth in section two B.”
