Building permits, zoning and land rules in Strafford County, New Hampshire

#9 of 10 in New Hampshire

Covered construction in Strafford County, New Hampshire requires a building permit and must meet the statewide building and fire codes, but Strafford County government does not issue it; the city or town does, under its own enforcement process1,2. Zoning is also set by each city and town rather than the county3. Septic permits are different again: the state Department of Environmental Services approves septic plans for every address in the county, with local sign-off added where a town requires it4.

Do you need a building permit in Strafford County, New Hampshire?

Yes, covered construction in Strafford County requires a building permit before work begins, and all buildings, building components and structures must comply with New Hampshire's statewide building and fire codes.

Yes, covered construction in Strafford County requires a building permit before work begins, and all buildings, building components and structures must comply with New Hampshire's statewide building and fire codes1,9. Strafford County government does not issue that permit: issuing building permits is reserved to the cities and towns that have a local enforcement mechanism, and procedures differ by municipality2. Where a municipality lacks local enforcement, the state permit system applies to covered work but excludes one- and two-family dwellings2. Identify the municipality before planning the project, then ask its building office which application and inspections apply; Dover's Inspection Services division is one municipal example, not the office for other communities11. Whether a certificate of occupancy is required is also a municipal choice2.

Who issues building permits in Dover, and how do you reach them?

Dover's Inspection Services division operates from 269 Mast Road, near the Public Works facility, and can be reached at 603-516-6038, Monday through Friday, 8 a.m. to 4 p.m..

Dover's Inspection Services division operates from 269 Mast Road, near the Public Works facility, and can be reached at 603-516-6038, Monday through Friday, 8 a.m. to 4 p.m11.. Permit and license applications can be submitted through Dover's online portal11. A building official must act on a complete ordinary residential application within 30 days, while the deadline is 60 days for nonresidential work or residential projects exceeding 10 dwelling units1. Dover's office serves only Dover; for land elsewhere, start with that municipality because Strafford County has no countywide building-permit office5.

Does Strafford County have zoning?

Strafford County does not administer countywide zoning; zoning is handled by its cities and towns.

Strafford County does not administer countywide zoning; zoning is handled by its cities and towns3. Subdivision rules are municipal too: New Hampshire allows an authorized municipal planning board to regulate subdivision plats and related street and utility plans6. The Town of Strafford shows what a town rule looks like: its ordinance makes the entire town an Agricultural-Residential District, requires at least 500 square feet of ground floor area for a single-family dwelling, and its Planning Board administers subdivision regulations for all land in town12,13. Do not apply those Town of Strafford rules to Dover or another municipality. For a Dover parcel, the city Planning Department can be reached at 603-516-6008 or dover-planning@dover.nh.gov14; Dover also requires a permit for any development in a mapped special flood hazard area15. Ask the parcel's own municipality about its zoning district, setbacks, allowed uses and subdivision review because no countywide answer was confirmed3.

How do septic permits work in Strafford County?

Septic systems anywhere in Strafford County, in every city and town, need construction approval from the state, not the county: New Hampshire's Department of Environmental Services approves the plans, which must be designed and submitted by a permitted New Hampshire septic system designer.

Septic systems anywhere in Strafford County, in every city and town, need construction approval from the state, not the county: New Hampshire's Department of Environmental Services approves the plans, which must be designed and submitted by a permitted New Hampshire septic system designer7. No one may construct a building that discharges sewage, or build a sewage disposal system, without the department's prior approval of the plans and specifications, and local requirements apply as well where a town requires its own prior approval4,16. A completed system can't be covered or placed in operation until it passes final inspection, which the department must complete within 7 business days of the builder's notice4,16. The state fee is $450 per system, due with the plans, and the department must respond within 15 working days of a complete submission4,17. An owner who installs a system on land that will be the owner's own domicile may do so by affidavit committing to live there for at least 2 years, but a permitted designer or installer must still certify the work18. Only about 4.8% of Strafford County's soil is free of severe limits for a conventional drain field, so budget for a careful site evaluation and possibly an engineered system19. If no public sewer sits within 100 feet of a dwelling, state law requires the wastewater to be conveyed underground or otherwise disposed of in a non-offensive manner20.

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

New Hampshire's recreational-campground rules only cover temporary occupancy, not permanent residency: they require a minimum campsite size for RVs at licensed campgrounds and explicitly limit occasional RV use on any other parcel to no more than 7 days per calendar year without a compliance filing to the town.

New Hampshire's recreational-campground rules only cover temporary occupancy, not permanent residency: they require a minimum campsite size for RVs at licensed campgrounds and explicitly limit occasional RV use on any other parcel to no more than 7 days per calendar year without a compliance filing to the town10. A year-round RV or tiny-home residence is a different question entirely, governed by whichever town's zoning ordinance covers the parcel, since Strafford County has no zoning of its own3. Ask the specific town's zoning office before you buy if living in an RV or tiny home is part of the plan; Dover's Planning Department is one example of who to call in that town14.

How do you build on land in Strafford County, step by step?

Identify the city or town containing the parcel because zoning and local permit administration are municipal.

  1. Identify the city or town containing the parcel because zoning and local permit administration are municipal3,5.
  2. Ask that municipality's planning office about the zoning district, allowed use, dimensional rules and subdivision approval; in the Town of Strafford, the Planning Board administers town subdivision regulations12.
  3. Confirm the correct permit path before starting covered construction, which requires a permit and statewide code compliance1,9.
  4. If the project needs septic, hire a permitted New Hampshire septic designer and obtain NHDES construction approval before work begins7,16.
  5. Check deeds and recorded easements through the Strafford County Registry of Deeds8.
  6. Request required construction inspections before work is concealed, then secure final septic approval and any applicable certificate of occupancy21,22.

What should you check before buying land in Strafford County?

The nearest city of 100,000 or more is about 29 miles from Strafford County's center, while the county averages 362.6 people per square mile.

The nearest city of 100,000 or more is about 29 miles from Strafford County's center, while the county averages 362.6 people per square mile19. About 86.2% of the land is wooded and 82% has a slope of 15% or less, but those countywide measures do not establish that a particular parcel is buildable19. Ask the parcel's municipality about permits, zoning and current land-use restrictions before closing3,5. Check soil suitability before budgeting for septic because only 4.8% of county soil is rated without severe limits for a conventional drain field19. Agricultural operations do not receive a blanket exemption from local dimensional, setback or driveway rules, although a limited waiver process may apply23. Confirm title and recorded easements through the Strafford County Registry of Deeds8.

Watch-outs

  • Do not mistake the lack of a Strafford County permit office for a permit exemption: covered construction requires a permit and statewide building-code compliance1,9.
  • The Town of Strafford's subdivision regulations are town-specific and should not be applied to parcels in Dover or another Strafford County municipality12.
  • No source found confirms an owner-builder exemption anywhere in Strafford County; ask the specific town's building office directly before assuming one applies2.
  • Septic plans need state approval, but a town can add its own prior-approval requirement, so ask the town before ordering a design16.

  • Building heightDistrict specific

    New Hampshire municipalities and qualifying counties may adopt local zoning regulations governing building height and number of stories; the exact height depends on the local ordinance and district.
