Plain-English answers to common homeowner questions, taken from Walpole's published bylaws, with every rule linked to the section it comes from.

• Accessory Dwelling Units (ADUs)
  Yes. Walpole's zoning bylaw allows one accessory dwelling unit (ADU) by right on a single-family lot in the Rural, Residence A, Residence B and General Residence districts, up to 900 sq ft or half the main home's floor area, whichever is smaller. You need a building permit; a detached ADU also goes through Limited Site Plan Review with the Building Commissioner, and short-term rentals of the ADU are prohibited.Allowed with a permit
• Backyard Chickens
  Yes, with a Board of Health animal permit. Zoning allows a small noncommercial flock of poultry in all residential districts, and the Board of Health regulations set no fixed hen limit: the number depends on space (at least 9 sq ft of roaming area per bird), and the coop must be at least 10 feet from any lot line. Roosters are not permitted if they create a noise nuisance.Allowed with a permit
• Short-Term Rentals (Airbnb / VRBO)
  We found no Walpole short-term rental bylaw, registration or local license in the zoning bylaw and other town documents we reviewed, but we could not check the town's general bylaws. The zoning bylaw defines short-term rentals (using the state definition in G.L. c. 64G) and prohibits them in accessory dwelling units (ADUs); it doesn't say whether renting your main home on Airbnb or VRBO is allowed, so ask the Building Department first. State registration and tax rules still apply.Restricted
• Fences
  Fences are allowed in Walpole's setbacks, but a wall or solid fence can be no more than 3 feet high between the street and the required front setback line (30 feet back in residential districts), and no more than 6 feet anywhere else. A fence counts as "solid" if it blocks more than 25% of the view; the bylaw sets no height limit for open fences such as split rail, and it does not itself require a fence permit.Allowed
• Sheds & Accessory Buildings
  Tool sheds are allowed by right as accessory buildings in every Walpole zoning district. A detached shed 15 feet tall or less needs only 10 feet from the rear lot line, but on most lots it must meet the district's full side setback (25 ft Rural, 20 ft Residence A, 15 ft Residence B, 10 ft General Residence); the reduced 6-foot side setback applies only if the shed sits at least 100 feet back from the front lot line. Sheds over 22 x 24 feet or 15 feet high must meet the full setbacks for a main building.Allowed
• Home-Based Businesses
  It depends on the business. A professional office or studio (lawyer, architect, artist, teacher, real estate or insurance agent and similar) is allowed by right in Walpole's residential districts with up to one non-resident employee and no more than four students at a time. Other customary home occupations and trades (beautician, cabinetmaker, contractor's workroom and the like) need a special permit from the Zoning Board of Appeals.Allowed with board review
• Swimming Pools
  Pools are allowed as accessory structures in Walpole. The zoning bylaw lets in-ground and above-ground pools sit inside the side and rear setbacks as long as the pool edge (or, for an above-ground pool, the edge of its elevated deck) is at least 6 feet from the lot line. Pool barrier and building permit rules come from the state code shown on this page.Allowed with a permit
• Building Near the Water (Wetlands Rules)
  Building, clearing or grading within 100 feet of a wetland, pond or stream (or the 100-year flood elevation, if that reaches farther), or within 200 feet of a year-round river or stream, needs a permit from the Walpole Conservation Commission under the town's Wetland Protection Bylaw. The Commission requires a 25-foot undisturbed vegetated buffer along the wetland edge unless it grants a variation.Allowed with board review
• Docks, Piers & Floats
  Walpole is inland and has no dock-specific rules: no local size limits, seasonal rules or dock permit. A dock, pier or float on a pond, river or stream still needs a Conservation Commission permit under the town Wetland Protection Bylaw, whose definition of "alter" includes driving piles, building structures and placing objects in water.Allowed with board review
