Does Erving, Massachusetts have zoning, and what does it mean for RVs, mobile homes and lot size?
Yes. The Town of Erving adopts and enforces its own zoning bylaw, Article 230, with Central Village, Village Residential, Rural Residential and French King districts plus floodplain and groundwater protection overlays1. The town publishes its official zoning map and the bylaw names it10.
In the Village Residential and Rural Residential districts, a lot needs at least 65,340 square feet and 175 feet of frontage78. Both districts require at least 20 feet for front, side and rear yards1112, and cap lot coverage at 50%13 and building height at 45 feet14.
RVs, camp trailers and motor homes may be occupied as a temporary dwelling for a maximum of 90 days per year, with a limit of two mobile units per parcel and no electrical, gas or septic service attached4. A mobile home or mobile home park is not permitted in any Erving district for year-round residence5. The one exception is a mobile home placed for up to 24 months on the site of a residence destroyed by fire, with permits from the building inspector and the board of health15.
We could not confirm whether the bylaw addresses tiny homes or sets a minimum dwelling size; ask the Town Planner.
Do you need a building permit in Erving, and who issues it?
Yes. Erving requires building permits for residential work, administered through the Franklin County Cooperative Inspection Program, which also covers plumbing, gas and electrical permits216. The program's page lists pools, decks, sheds, carports and interior and exterior renovations among the work it covers16. Erving is a member of the program16.
The Massachusetts State Building Code is the code for buildings in every Massachusetts town, enforced by the local inspector17. A person building their own home is exempt from home-improvement-contractor registration, but that is not an exemption from building permits or inspections9.
We could not confirm Erving's permit fees, inspection schedule or certificate-of-occupancy rules; ask the building inspector's office before you budget.
How do septic permits work in Erving?
Septic permits for a house with up to four dwelling units are issued by the town board of health, not by the county or the zoning board3. The Erving Health Department is the office to ask18. State Title 5 sets the minimum standards, and the local board administers permits19.
An application includes deep observation holes, percolation test results and a plan that meets the state sanitary code and local health regulations. If the board does not decide within 45 days, the permit is deemed granted3.
Soil matters here: only about 1.4% of soils in Franklin County rate as not limited for a conventional drain field, so expect a site evaluation and possibly an engineered system20. We could not confirm Erving's own septic, well or sewer-connection rules; the Board of Health can tell you whether a lot is on town sewer.
Can you build a second dwelling or live in an RV on your land in Erving?
An RV can serve as a temporary dwelling for a maximum of 90 days per year in Erving, with no permanent structure or utility service attached4. Living in an RV while you build a house is therefore not a long-term option. In flood zones, RVs must be elevated and anchored, stay on site fewer than 180 consecutive days, or be fully licensed and highway ready4.
A detached accessory dwelling unit needs a special permit from the planning board, must be a complete unit with its own entry, kitchen and bathroom, and may not exceed 900 square feet6. Massachusetts law also protects a single accessory dwelling unit in a single-family zoning district, though towns may apply reasonable setback, height and site-plan rules21.
Building a home in Erving: the steps, in order
- Confirm the district on the town's official zoning map and check lot size and frontage against Article 23010.
- If you are dividing land, submit a plan to the planning board first; Erving also has local subdivision regulations2223.
- Contact the Erving Health Department about septic design, soil testing and well questions318.
- Apply for building, plumbing, gas and electrical permits through the Franklin County Cooperative Inspection Program216.
- Ask the Town Planner about special permits, such as an accessory dwelling624.
What stays with Franklin County and the state, and what to check before you buy in Erving
Franklin County has no county government that sets rules for Erving; zoning is adopted by each town25. For land outside Erving, see the Franklin County page.
Check whether the lot lies in the floodplain overlay, where extra rules apply1. Franklin County's effective property tax rate is 1.5%26, and the typical home is valued at about $379,65627. About 86.6% of the county is wooded28, so expect clearing and access costs on raw land.
Watch-outs
- Erving's zoning bylaw bars mobile homes as year-round residences in every district5.
- RV occupancy is capped at 90 days per year, so an RV is not a place to live while building4.
- Erving has floodplain and groundwater protection overlay districts1; we could not confirm their permit requirements, Erving’s fees or driveway permit rules, so ask the building inspector’s office and the Town Planner before you buy.
- The permit rules in the Erving bylaw date from the version adopted in May 2023, so ask the Town Planner whether later amendments apply1.
