Zoning, building permits and septic rules in Sunderland, Massachusetts

The Town of Sunderland, Massachusetts has its own zoning bylaw, so building on a lot there means meeting town rules, not county rules1. Building permits come from the town's Building Commissioner2, and a building permit is required under the state code3. Septic permits come from the town Board of Health4. Franklin County has no county government to ask5.

Does Sunderland, MA have zoning, and what does it mean for lot size and setbacks?

Yes. The Town of Sunderland administers its own Zoning Bylaw, Chapter 125 of the town code, and the zoning applies only inside the town limits1. The bylaw divides the town into Village Residence (VR), Rural Residence (RR), Village Center, Commercial 1 and Commercial 2 districts, plus three overlay districts for prime agricultural land, critical resources and watershed6.

Lot rules depend on the district. In Village Residence, the table lists a 20,000 square foot minimum lot with 120 feet of frontage8. In Rural Residence, the minimum is 32,000 square feet with 150 feet of frontage, rising to two acres in the prime agricultural and critical resource overlays9. The watershed overlay asks for three acres and 200 feet of frontage, with an exception on Route 116, Bull Hill Road and East Plumtree Road9.

Front yards are 25 feet in Village Residence12 and 30 feet in Rural Residence13, and building coverage tops out at 25 percent of the lot in both districts1415. Several footnotes modify these numbers, so confirm the figures for a specific parcel with the Building Commissioner before relying on them. Sunderland's own rules on RVs, tiny homes and manufactured homes are unconfirmed; ask the Building Commissioner at 413-364-77822.

Do you need a building permit in Sunderland, and who issues it?

Yes. A building permit is required under the Massachusetts State Building Code, and Sunderland enforces it through its own inspector rather than a county office3. The state code is the code for every building and structure inside a city or town16.

The Sunderland Building Inspector / Commissioner states that online building permits are required for all building activities and asks applicants to allow 30 days to process applications2. Inspectors keep no regular office hours but take appointments2. Reach the office at 413-364-77822.

Homeowners building their own primary residence may apply for the permit themselves under the state's homeowner exemption, which waives the construction supervisor license, not the permit11. Registration as a home-improvement contractor is also not required of people building their own home17.

How do septic permits work in Sunderland?

Septic permits in Sunderland come from the town's Board of Health, not from a county or the state. The Board of Health office lists all septic and Title 5 services among the matters handled by its administrator at 413-665-1441, extension 64. The state's Title 5 code sets the minimum standards, and the local board administers permits18.

A complete application needs deep observation holes, percolation test results and a plan that meets the state sanitary code7. The board must act on a completed application within 45 days or the permit is deemed granted7. The town contracts a Health Agent for soil evaluations and wells4.

Sunderland has its own Board of Health regulation on subsurface sewage disposal in Chapter 172 of the town code19, and we could not confirm its terms or fees; ask the Board of Health. Franklin County soils rate poorly for conventional drain fields, with about 1% rated not limited, so expect a thorough site evaluation and possibly an engineered system20. Sunderland's well permit rules are also unconfirmed; ask the Board of Health, since a town may require a local site permit for private wells21.

Can you live in an RV or tiny home on your land in Sunderland?

Sunderland's rules for living in an RV, camping on private land or placing a tiny home or manufactured home are not confirmed, so ask the Building Commissioner before buying land for that purpose2. Do not assume the answer is yes because no rule has been found.

State law gives limited help. A single accessory dwelling unit is protected in a single-family zoning district, up to the smaller of half the main home's floor area or 900 square feet, though towns may apply setbacks, site plan review and short-term rental limits22. A manufactured home may be placed on the site of a residence destroyed by fire or another natural holocaust for up to 12 months while it is rebuilt23. The state's tiny-house statute applies only in designated seasonal communities24.

Building a home in Sunderland: the steps, in order

  1. Confirm the parcel's zoning district (Village Residence, Rural Residence or an overlay) and check lot size, frontage and setbacks against the Zoning Bylaw6.
  2. If you are dividing land, plan on subdivision review, since Sunderland regulates the division of land in Chapter 194 of its town code25; state law sends subdivision plans to the town planning board26.
  3. Call the Board of Health at 413-665-1441, extension 6, for soil evaluation and Title 5 septic design4.
  4. Apply for the building permit online through the Building Commissioner2.
  5. Pick up a driveway entrance permit from the Highway Department or the Town Office Building, which requires a fee of $2510.
  6. Schedule inspections through the Building Commissioner and finish septic inspections with the Board of Health24.

What stays with Franklin County, and what to check before you buy in Sunderland

Franklin County, Massachusetts has no county government that issues building permits or sets zoning, so every land-use rule for a Sunderland parcel comes from the town or the state5. For land outside Sunderland, see the Franklin County page.

Before buying, ask the town about floodplain limits, public sewer and water connection, and fees, none of which we could confirm. Sunderland's code includes flood hazard area rules and a sewer chapter19. County-level figures: Franklin County's effective property tax rate is 1.5%27, and about 87% of its land is wooded28.

Watch-outs

  • Several footnotes to Sunderland's dimensional table change setbacks and heights for some uses, so have the Building Commissioner confirm the numbers for your parcel12.
  • Sunderland's rules on RVs, camping, tiny homes, manufactured homes and accessory dwellings were not confirmed; call the Building Commissioner at 413-364-7782 before you buy2.
  • Septic and well fees and local Board of Health terms were not confirmed; ask the Board of Health at 413-665-1441, extension 64.
  • Online building permit applications can take a long time, so build the 30-day processing window into your schedule2.
