Building permits, zoning and land rules in Aroostook County, Maine
78Index Score / 100 #13 of 16 in Maine
In Aroostook County, Maine, the Land Use Planning Commission (LUPC) issues building permits and sets zoning in unorganized and deorganized territory, while organized municipalities apply their own local rules123. Septic permits are required before any new, expanded or replacement system, and Maine CDC's statewide rules apply in towns and LUPC territory alike45.

Do you need a building permit in Aroostook County, Maine?
A new house or camp or an expansion of an existing residential structure in Aroostook County's LUPC-served unorganized and deorganized territory generally needs an LUPC building permit; qualifying accessory structures are excepted1. State law requires a commission permit for residential development in that service area, although normal maintenance or repair may be exempt outside special flood-hazard areas11. Organized municipalities apply their own local ordinances and permit systems, so the parcel's jurisdiction determines the first office to contact3. Maine's Uniform Building and Energy Code must be enforced in municipalities with more than 4,000 residents, while smaller municipalities may choose to enforce it12. Where MUBEC enforcement is mandatory or elected, inspections are part of enforcement; municipalities with up to 4,000 residents are not required to conduct that enforcement13. Compliance remains the building owner's responsibility even where a smaller municipality does not enforce MUBEC14.
Who issues building permits and zoning approval in Aroostook County?
Aroostook County's website directs owners in an organized municipality to that municipality and owners in unorganized territory to the Land Use Planning Commission15. The LUPC Caribou office is the regional contact, but completed building applications are sent by email or mail to LUPC's Augusta office; a new or expanded sewage-disposal system requires a signed HHE-200 with the application1615. LUPC publishes its application forms and supporting instructions17. LUPC also requires commission permitting for residential and nonresidential subdivisions in its jurisdiction18. The Aroostook County Commissioners' Office is the general county contact for questions that do not fit the state or municipal channels19. Maine CDC administers statewide septic rules and licensing, while towns and Local Plumbing Inspectors assigned to unorganized territory submit permits and participate in administration and inspection5.
Does Aroostook County have zoning?
Aroostook County does not have one zoning answer for every parcel: LUPC is the planning and zoning authority in unorganized and deorganized areas, including townships and plantations within its service area, while organized municipalities must be checked individually23. An LUPC applicant must use the relevant Land Use Guidance Map to identify the parcel's subdistrict and whether the proposed activity is allowed, standards-based, permit-required, a special exception or prohibited20. In LUPC territory, residential uses and residential campsites generally need 40,000 square feet per dwelling or campsite; the figure falls to 20,000 square feet with common or community sewer and no onsite disposal, while a campsite-only lot has no minimum8. General standards cap impervious coverage at 30% and residential height at 75 feet, with shoreland and subdistrict exceptions2122. Setbacks likewise depend on the subdistrict, use and Chapter 10 exceptions, so ask the LUPC Caribou office to check the parcel before designing915.
How do septic permits work in Aroostook County?
A permit is required before installing, expanding or replacing a septic system or component in Aroostook County; normal maintenance and repair are excepted4. A septic permit is valid for work that begins within 24 months of issuance23. A licensed site evaluator normally prepares a non-engineered application after evaluating the site, while a professional engineer or licensed site evaluator may prepare an engineered application24. Maine CDC administers statewide rules and licensing, while towns and Local Plumbing Inspectors assigned to unorganized territory take part in permit administration and inspection5. A new system must pass two inspections: site preparation before installation and another before final backfilling25. Alternative toilets and other off-grid sanitation arrangements remain subject to wastewater rules and site conditions; limited application exceptions do not create a blanket exemption26. Only 3.5% of county soils avoid severe limitations for a conventional drain field, so make the site evaluation a pre-purchase priority27. A shoreland-zone property transfer involving a septic system also requires inspection by a certified inspector25.
Can you live in an RV or tiny home on your land in Aroostook County?
A personal campsite in Aroostook County's LUPC territory may use tents, registered campers, trailers or RVs for no more than 120 days per calendar year; it must be private, noncommercial, limited in structures and without pressurized water7. More intensive use is treated as a residential dwelling and may require onsite sewage disposal, while a public or rented campsite requires a Development Permit7. We could not confirm a countywide rule for long-term RV residence or tiny-home occupancy outside that campsite rule. Manufactured homes in LUPC floodplain-regulated areas must meet special elevation, permanent-foundation and anchoring standards, but those standards do not settle manufactured-home occupancy countywide28. A short-term rental in LUPC territory is allowed only in a subdistrict that allows dwellings or residential campsites, and the operator must file notice with LUPC29. Ask the town or LUPC Caribou office about the exact unit and proposed occupancy before buying or placing it15.
Building a home in Aroostook County: the steps, in order
Confirm whether the parcel is in an organized municipality or LUPC-served territory; that decides who handles building and zoning3.
Ask the town or LUPC Caribou office to identify the applicable zoning rules and parcel-specific standards2015.
For a new house, camp or residential expansion in LUPC territory, complete the published form and send the application to the Augusta office before work begins116.
Check LUPC's Chapter 1 fee schedule; wastewater fees also vary by system type10.
Have the septic site evaluated, obtain the permit through the town or assigned Local Plumbing Inspector, and schedule both installation inspections525.
If the site is flood-prone, include LUPC's floodplain-development supplement and account for the additional standards30.
If land will be divided, obtain LUPC subdivision approval and satisfy recording and compliance requirements before conveyance31.
What to check before you buy land in Aroostook County
Aroostook County is sparsely settled, with about 10.1 people per square mile, and the nearest city of 100,000 or more is about 287 miles from the county's center3233. About 87.9% of the county is wooded and 92.2% of its land has a slope of 15% or less3435. Soil is the sharper building constraint: only 3.5% of county soils avoid severe limitations for a conventional septic drain field, so obtain a site evaluation before committing to a homesite27. Confirm whether the parcel is in an organized town or LUPC territory, then identify its mapped subdistrict, shoreland setbacks and flood exposure before closing20936. Aroostook farmland averages about $2,403 an acre, while the typical home value is about $173,8573738. The effective property-tax rate is about 1.2%, and the median annual property-tax bill is about $1,6113940. We could not confirm a countywide private-well permit rule or general driveway-access rule; ask the town or LUPC Caribou office which authority handles the parcel15.
Watch-outs
Building and zoning authority changes at the organized-municipality boundary: contact the municipality there and the Land Use Planning Commission in its service area315.
Maine's owner-builder provision (Title 10, section 1489) only lets a homeowner and contractor exempt their construction contract from certain consumer-protection terms; it does not waive a building permit, inspection or certificate of occupancy that otherwise applies416.
A personal campsite in LUPC territory limits tents, registered campers, trailers and RVs to 120 days per calendar year; ask the town or LUPC Caribou office about any residential use715.

The unit must be at least 190 square feet unless the Technical Building Codes and Standards Board adopts a different minimum size; a municipality may impose a maximum size.
The unit must comply with applicable shoreland zoning requirements and may not be categorically prohibited in a qualifying shoreland zone.
Before certification for occupancy, the owner must provide written verification of adequate water and wastewater service, including the statute's sewer, septic, public-water and well documentation requirements.
A municipality is not required to implement the requirements until the statutory implementation date; valid private restrictions may impose greater restrictions.

Off-grid sanitationLimited
Off-grid sanitation using subsurface wastewater disposal systems, graywater systems, pit privies, or alternative toilets anywhere in Maine.
A new, expanded, or replacement subsurface wastewater disposal system or any individual component generally requires a permit before work starts.
Normal maintenance and repair are excepted from the permit requirement.
Replacement septic tanks and alternative toilets are exceptions to the application site-evaluation requirement; alternative toilets other than pit privies are identified as exceptions.
Work must not begin until the Licensed Plumbing Inspector issues the disposal-system permit.
Permit applications generally require preparation by a licensed site evaluator for non-engineered systems or by a professional engineer or licensed site evaluator for engineered systems.
Sites must have passing soils and meet applicable setbacks.
A disposal-system permit is valid for work commenced within 24 months after issuance.
The current state fee schedule lists $100 for a Primitive/Limited System (graywater and alternative toilet), $50 for an Alternative Toilet, and $250 for a Complete Non-Engineered System, with listed 25% and water-quality-surcharge amounts where applicable.
Local plumbing inspectors and municipal ordinances may administer or add applicable requirements.

“Permit applications must be prepared by a licensed site evaluator (for non-engineered systems) or a professional engineer or a licensed site evaluator (for engineered systems),and require a site evaluation. Exceptions are replacement septic tanks and alternative toilets, other than pit privies.”
Well permitLimited
New public water sources and significant groundwater wells in Maine; the cited sources do not establish a general permit requirement for every private residential well.
Before construction of a new public water source, proposed plans must be submitted to the Drinking Water Program for approval.
Before a new public-water-source well is drilled, the selected site must be approved by the Drinking Water Program.
Public-water-source wells generally require a 300-foot setback from potential contamination sources such as fuel tanks and leach fields; a waiver may be requested if site conditions require it.
Final public-water-source approval requires well construction information, a pump test of at least 48 hours, and water-quality testing to drinking-water standards.
A person may not establish or operate a significant groundwater well without first obtaining a DEP permit under the NRPA.
A DEP NRPA permit is not required for a significant groundwater well when a permit is already required under the Site Law, borrow-pit laws, quarry laws, or LUPC statutes.
Wells in unorganized areas of Maine are regulated by the Land Use Planning Commission.
The cited public-water-source approval page concerns public water sources and does not state a universal permit requirement for ordinary private residential wells.
well setback from potential contamination sources: >= 300 feet (waiver may be requested if site conditions require it) · minimum public-source pump test: >= 48 hours (final approval testing)
“Under the NRPA, a person may not establish or operate a significant groundwater well without first obtaining a permit from the DEP. A NRPA permit is not required if a permit is already required pursuant to the Site Law, borrow pit laws, quarry laws, or Land Use Planning Commission (LUPC) statutes.”
Mandatory utility hookupConditional
Wastewater sewer connections where a public sewer or sanitary/sewer district is available in Maine.
A sanitary-district connection may be required after the district requests it, generally within 90 days, when the building is within 200 feet of the district sewer or drain.
A municipality may require connection by ordinance when a building abuts a street or public way containing a sewer.
An existing compliant private sewer or drainage system is exempt from sanitary-district connection requirements while it remains satisfactory, sanitary, and compliant with applicable law, ordinance, and the state plumbing code.
The sanitary-district rule does not require acquiring real property or an easement solely to make the connection.
sanitary-district accessibility distance: <= 200 feet (no easement acquisition is required solely for connection) · connection deadline after sanitary-district request: 90 days (trustees may grant additional time)
“Existing buildings that are already served by a private sewer or drainage system are not required to connect with any sewer or drain of the district so long as the private sewer or drainage system functions in a satisfactory and sanitary manner, and does not violate any law or ordinance applicable thereto or any applicable requirement of the state plumbing code, as determined by the municipal plumbing inspector, the inspector's alternate, or, in the event that both are trustees or employees of the district, the Division of Health Engineering.”

Driveway accessRequired
Projects submitted through the Maine Land Use Planning Commission building-permit process in the LUPC service area.
A Driveway/Entrance Permit from MaineDOT must be obtained and submitted with the LUPC application when proposing a driveway or entrance regarding a state or state-aid road.
The same permit requirement applies when proposing to increase traffic volume or potentially create a safety or drainage concern.
If required for a new driveway off a county, town, or plantation road, that local permit must also be obtained and submitted with the LUPC application.
For county, town, or plantation road requirements, applicants must contact the County Commissioners’ office or Town/Plantation office.
“you must obtain a Driveway/Entrance Permit from the Maine Department of Transportation (MDOT) and submit it with your application.”
Campground & park staysLimited
Recreational-vehicle occupancy at campgrounds on 5 or more sites operated for compensation or indirect compensation statewide in Maine.
A campground is defined to include recreational vehicle parks and sites intended for recreational purposes rather than permanent residency.
A person may not operate a campground for compensation or indirect compensation without a license issued by the Maine Department of Health and Human Services.
If a campground consists of 5 or more tents or recreational vehicles on a commercial lot, compensation is presumed regardless of fees charged, but the owner or renter may rebut the presumption by a preponderance of the evidence.
minimum recreational vehicle sites triggering compensation presumption: >= 5 sites (On a commercial lot; the presumption may be rebutted by a preponderance of the evidence.)

county zoning authorityLimited
Maine counties seeking zoning for unorganized or deorganized territory within the jurisdiction of the Maine Land Use Planning Commission.
A county may request the Maine Land Use Planning Commission to develop and implement the regional comprehensive land use plan and associated zoning; the quoted statute does not grant the county independent statewide authority to adopt and administer general zoning.
The request may be made by one county or in partnership with another county or counties.
The zoning may cover all or only a portion of territory within the commission's jurisdiction in the requesting county or counties.
For mandatory shoreland zoning, the current statute expressly assigns adoption of zoning and land-use-control ordinances to municipalities; it does not identify counties in that operative grant.
“A county, separately or in partnership with another county or counties, may request the commission to develop and implement a regional comprehensive land use plan and associated zoning for all or a portion of the territory within the jurisdiction of the commission in the county or counties making the request.”
county building authorityLimited
Residential building-permit administration by Maine counties in unorganized or deorganized territory under the jurisdiction of the Maine Land Use Planning Commission.
The Maine Land Use Planning Commission must establish standards for delegation.
Delegation occurs only upon request of the county commissioners.
The delegation is limited to specified activities requiring a permit.
The county may approve, approve with reasonable conditions, or deny applications and enforce compliance with the permit.
A person aggrieved by a county decision may appeal to the commission within 30 days after the county decision.
The LUPC states that, except for accessory structures meeting LUPC standards, building a new house or camp or expanding an existing residential structure generally requires an LUPC building permit.
The cited sources establish delegated permit authority, not general county authority to adopt an independent residential building code.
“The commission may establish standards by which authority may be delegated to a county, upon request of the county commissioners, to approve, approve with reasonable conditions or deny applications to conduct specified activities requiring a permit and to enforce compliance with the permit.”
Set by your town or city, not the county
In Maine, zoning is adopted by each town or city, so Aroostook County has no county-wide answer on these. Find your town or city in the list of places on this page, or call its clerk or zoning administrator.
