Building permits, zoning and land rules in Norfolk County, Massachusetts
35Index Score / 100 #13 of 14 in Massachusetts
Norfolk County, Massachusetts has no county building authority: building permits are issued by the city or town where the land sits under the Massachusetts State Building Code1. Each municipality also administers its own zoning2. Septic systems follow statewide Title 5, with permits issued by the local Board of Health3. Quincy is the worked example here; contact the offices serving your parcel before buying or building.

Do you need a building permit in Norfolk County, Massachusetts?
Yes, but Norfolk County itself does not issue it: the county has no building authority, and building permits statewide come from the city or town where the property sits, enforcing the Massachusetts State Building Code (780 CMR)1. In the City of Quincy, the county seat, the Inspectional Services Department's Building Division reviews and issues these permits, and this guide uses Quincy as a worked example of the process you will find in any Norfolk County municipality8. Your own city or town, whether Quincy, Brookline, Milton, Wellesley, Wrentham or any other municipality in the county, has a separate building department you must contact directly. Search "[your town] building department" or check your town's official website to find the correct office before you buy or build.
Who issues building permits in Norfolk County, and how do you reach them?
There is no single Norfolk County building office to call. As a worked example, Quincy's Inspectional Services Department is at 55 Sea St, Quincy, Massachusetts, phone (617) 376-1450, and it runs a walk-in zoning clinic every Thursday afternoon8. The Quincy department also conducts inspections during construction and ongoing public-safety inspections of existing buildings, although the source does not establish one inspection schedule for every project9. Every other city and town in the county maintains its own equivalent office, so confirm the correct department for your parcel before using Quincy's contact details1.
Does Norfolk County have zoning?
Yes, but zoning in Norfolk County is entirely a city and town function; there is no countywide zoning map or ordinance2. Statewide, Massachusetts zoning law bars a city or town from regulating the interior floor area of a single-family residential building through zoning, though the state building code's own space requirements still apply6. Statewide law also requires every city and town to allow at least one accessory dwelling unit by right on a lot in a single-family residential zoning district, subject to reasonable rules like setbacks, septic compliance and limited added parking; a second ADU on the same lot needs a special permit5. Communities served by the MBTA, several of which are in Norfolk County, must also zone at least one district for multifamily housing as of right near transit, which can affect land near a commuter rail or subway stop even in an otherwise low-density town10.
How do septic permits work in Norfolk County?
Septic systems across Norfolk County follow the statewide Title 5 code (310 CMR 15.000), but the disposal-system construction permit itself is issued locally by your city or town's Board of Health, not by the county or the state directly3. In Quincy, the Health Department's Environmental Health division handles this work, reachable at (617) 376-1275, and it is shown here only as a worked example; your own town's Board of Health is a different office11. If your parcel already abuts a public sewer, Massachusetts law can require you to connect your sewage line to it under the direction of the local officer who maintains that sewer, rather than installing a new septic system12. Ask your town's Board of Health directly whether public sewer is available at your specific parcel before you budget for a septic system.
Can you live in an RV or tiny home on your land in Norfolk County?
Massachusetts has a specific tiny-house law for municipalities designated as seasonal communities. A qualifying municipality must adopt a bylaw or zoning ordinance allowing tiny houses for year-round housing, and each tiny house must meet state and local building-code requirements13. A separate, narrow state rule lets an owner place a manufactured home on the site of a residence destroyed by fire or another disaster for up to 12 months while rebuilding; that is not a general RV or tiny-home occupancy rule14. We could not confirm a rule for long-term RV or ordinary tiny-home occupancy across Norfolk County; ask the building and zoning office for the city or town where the parcel lies.
Building a home in Norfolk County: the steps, in order
Identify the exact city or town your parcel sits in and find that municipality's own building department and zoning office; Norfolk County itself has neither12.
Confirm the parcel's zoning district and any accessory-dwelling, setback or lot-coverage rules with that town's zoning office25.
If the site will use a septic system, work with your town's Board of Health under the statewide Title 5 code (310 CMR 15.000); if a public sewer is already available at the property, your town may require you to connect to it instead312.
If the land qualifies as commercial agricultural use on 5 or more acres, or on 2 or more acres meeting the state's sales-per-acre test, know that local zoning cannot unreasonably restrict that farm use7.
Apply for your building permit with your town's building department; in Quincy, for example, this is the Inspectional Services Department's Building Division8.
Build to the Massachusetts State Building Code (780 CMR), which applies statewide regardless of which Norfolk County municipality you are in1.
Arrange the inspections required by your municipality; Quincy, for example, conducts inspections during construction and ongoing public-safety inspections, but its published description does not set one schedule for every project9.
What to check before you buy land in Norfolk County, Massachusetts
Confirm the exact city or town first: each of Norfolk County's municipalities sets its own zoning, permitting and septic rules, so a parcel two towns apart can face very different requirements2. If the site needs a septic system, talk to that town's Board of Health about Title 5 suitability before you make an offer, and ask specifically whether a public sewer connection would be required instead312. Federal land is essentially absent in Norfolk County, about 1% of its area, so land availability here is a private real-estate question, not a federal-land question15. Property taxes run meaningfully higher than in many rural counties: Norfolk County's effective rate is about 1.1%, with a median annual bill near $7,081, so factor that into your holding costs1617. If you are weighing an accessory dwelling unit for rental income or family housing, remember state law now guarantees one by right in a single-family zone in every city and town, subject to each town's reasonable local conditions5.
Watch-outs
This guide could not confirm a Norfolk County or municipal owner-builder exemption from contractor licensing; ask your specific city or town's building department directly4.
We could not confirm a rule for long-term RV or ordinary tiny-home occupancy across Norfolk County; because zoning is administered by each city or town, ask the building and zoning office serving the parcel before relying on that use2.

Answers from the rulebook for Norfolk County
What the ordinances and state agencies actually say — one answer per question, each quoted from the official source and independently re-checked.
Norfolk County rules
Building permitRequired
Norfolk County has no county building authority; building permits are issued by municipal building inspectors under the Massachusetts State Building Code (780 CMR), e.g. the City of Quincy Inspectional Services Building Department.
Zoning is administered at the municipal level; each city/town in Norfolk County (e.g. Quincy, with its Zoning Board of Appeals) has its own zoning ordinance.
Who permits septicMassDEP Title 5 (310 CMR 15.000), administered by the local Board of Health
Septic systems are governed by the statewide State Environmental Code Title 5 (310 CMR 15.000) under MassDEP, with disposal system construction permits issued by the local Board of Health.
Massachusetts zoning districts, including the statutory requirement applicable to MBTA communities and locally adopted zoning districts.
Zoning ordinances and bylaws are adopted by cities and towns; the statewide statute does not provide one uniform zoning map or complete statewide district inventory.
For an MBTA community, at least one reasonable-size district must permit multifamily housing as of right, without age restrictions and suitable for families with children.
The required MBTA-community district must have a minimum gross density of 15 units per acre, subject to limitations under chapter 131 section 40 and Title 5 of the state environmental code, and must be within 0.5 miles of a commuter rail station, subway station, ferry terminal, or bus station, if applicable.
Local zoning amendments generally require public hearings and a two-thirds vote, subject to statutory exceptions.
minimum gross density: >= 15 units per acre (Subject to further limitations imposed by section 40 of chapter 131 and Title 5 of the state environmental code.) · maximum distance from applicable transit: <= 0.5 miles (Applies to the MBTA-community district when a qualifying commuter rail station, subway station, ferry terminal, or bus station is applicable.)
“An MBTA community shall have a zoning ordinance or by-law that provides for at least 1 district of reasonable size in which multi-family housing is permitted as of right; provided, however, that such multi-family housing shall be without age restrictions and shall be suitable for families with children.”
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”
Tiny homesLimited
Tiny-house dwelling occupancy in municipalities designated as Massachusetts seasonal communities.
A tiny house must be a detached structure containing a dwelling unit of 400 square feet or less, excluding lofts.
The seasonal community must adopt bylaws or zoning ordinances permitting construction of tiny houses.
Tiny houses must be designated for year-round housing and meet all state and local building-code requirements.
Any qualifying undersized-lot housing may not be used as a seasonal home or short-term rental of less than 6 months and must be used as year-round housing.
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”
Manufactured homesLimited
Placement and occupancy of a manufactured home on the site of a Massachusetts residence destroyed by fire or another natural holocaust while the residence is being rebuilt.
The person must be the owner and occupier of the destroyed residence.
The manufactured home must be placed on the site of that residence.
Occupancy may not exceed 12 months while the residence is being rebuilt.
The manufactured home remains subject to the Massachusetts state sanitary code.
maximum occupancy period: <= 12 months (While the residence is being rebuilt.)
“period not to exceed twelve months while the residence is being rebuilt.”
Accessory dwellingsAllowed (with conditions)
A single accessory dwelling unit, or its rental, in a single-family residential zoning district in Massachusetts cities and towns.
The use may be subject to reasonable regulations, including applicable 310 CMR 15.000 requirements, site-plan review, dimensional setbacks, and bulk and height regulations.
Municipal restrictions or prohibitions on short-term rental may apply.
Owner occupancy of either the accessory dwelling unit or principal dwelling is not required.
No more than one additional parking space may be required.
No additional parking space may be required 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 rental thereof, in a single-family residential zoning district requires a special permit.
The unit must otherwise satisfy the statutory definition, including sleeping, cooking, and sanitary facilities, a separate entrance, and a maximum gross floor area of the lesser of one-half the principal dwelling's gross floor area or 900 square feet.
maximum gross floor area: the lesser of 50% of the principal dwelling's gross floor area or 900 square feet · additional parking spaces: <= 1 space per accessory dwelling unit (No additional space may be required within 0.5 miles of a commuter rail station, subway station, ferry terminal, or bus station.)
“No zoning ordinance or by-law shall prohibit [...] a single accessory dwelling unit”
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.”
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”
