Franklin County, New York does not have one countywide building-permit desk: the town or village where the parcel lies administers permits for work covered by the state codes12. Zoning is also municipal, while the County Planning office reviews certain local zoning actions34. Septic plans go through the New York State Department of Health Saranac Lake District Office, which serves Franklin County56.

Do you need a building permit in Franklin County, New York?
Yes, covered construction in Franklin County requires a building permit, but the authority having jurisdiction is the parcel's town or village rather than a single county building department12. New York's minimum enforcement rules require permits for work that must conform to the Uniform Code or Energy Code, while allowing each local authority to exempt listed minor work categories2. A qualifying detached shed or similar one-story accessory structure may be exempt when it is no larger than 144 square feet, but the municipality may instead require permits for all covered work2. Permit-exempt work must still comply with the applicable codes2. Applications for regulated work submitted under the current regime must comply with the state code books adopted for 202510.
Who issues building permits in Franklin County, and how do you reach them?
The code-enforcement office for the town or village containing the parcel issues the building permit and conducts required construction inspections111. Franklin County publishes a roster of municipal code-enforcement officials, but buyers should identify the municipality from the tax map and contact that office before preparing an application1. Franklin County Planning is not the building-permit office; it reviews qualifying zoning actions referred by towns and villages, including zoning amendments, comprehensive plans, special permits, site plans and variances4. Permit fees are not uniform across Franklin County because local authorities can impose their own schedules, so request the current application and fee sheet from the relevant municipal code office12. Keep permitted work accessible until the municipality has inspected and accepted it11.
Does Franklin County have zoning?
Franklin County does not supply one countywide zoning answer for a rural parcel; towns and villages may adopt and administer their own zoning laws34. The County Planning office has an advisory referral role when a municipality considers specified zoning actions affecting property near municipal boundaries, public land, certain roads, drainage channels or agricultural districts4. That split matters: an address marketed as being in Franklin County may still face town or village rules for use, setbacks, lot size, building height, accessory dwellings and site-plan approval3. No complete countywide schedule for those standards was confirmed, so ask the parcel's town or village code-enforcement office for the zoning map, use table and dimensional standards before relying on a listing description3. A proposed subdivision may also require municipal planning-board review where the town board has authorized that process13.
How do septic permits work in Franklin County?
Wastewater-disposal plans in Franklin County must be approved before construction by the responsible health authority, and the New York State Department of Health Saranac Lake District Office serves Franklin County56. Call that district office early to confirm the application, design and inspection path for the specific parcel6. A residential system discharging less than 1,000 gallons per day to groundwater, with no industrial or other non-sewage waste, does not require a state SPDES permit, but health-department approval may still be required14. Soil is a serious siting constraint here: only about 0.6% of county soils are rated without severe limitations for a conventional septic drain field15. That rating supports making septic feasibility a purchase contingency rather than assuming a conventional field will work15.
Can you live in an RV or tiny home on land in Franklin County?
Franklin County has no confirmed countywide answer for long-term RV occupancy, temporary camping, tiny-home occupancy or minimum dwelling size, because those land-use questions can turn on the town or village3. Ask the municipal code-enforcement office whether the parcel's district allows the proposed use and whether rules on setbacks, lot size or accessory dwellings apply3. A tiny home built as a dwelling is still subject to the permit framework for work that must conform to the state codes2. A manufactured home has a clearer rule: installation, alteration and covered repair work require a building permit, and occupancy follows the certificate process for permitted work816. A manufactured-home owner may seek installer certification, but that is not a general owner-builder exemption from permits or code compliance7.
Building a home in Franklin County: the steps, in order
- Identify the parcel's town or village, then ask its code-enforcement office for the zoning map, allowed-use rules and current building-permit application13.
- Contact the Saranac Lake District Office before finalizing the site plan so the wastewater design follows the applicable health-approval path56.
- If access will cross a county road, contact the Franklin County Highway Department about its driveway-structure permit before building the entrance9.
- Submit the building application with the work location, scope, tax-map number, occupancy classification and acceptable construction documents required by the local code program17.
- Schedule the municipality's required inspections and leave covered work exposed until it is accepted11.
- Obtain a certificate of occupancy or compliance before using work for which a building permit was required16.
What should you check before buying land in Franklin County?
Confirm the municipality first, because town or village jurisdiction determines the zoning and building-permit contact13. Make a satisfactory septic evaluation a contract contingency because only about 0.6% of Franklin County soils avoid a severe conventional-drain-field limitation15. Terrain and clearing also belong in the budget: about 72% of the county is at a slope of 15% or less, while about 83.7% is wooded1819. For road access, determine whether the frontage is municipal, county or state maintained; the County Highway Department publishes a permit specifically for driveway structures on county roads9. Budget ongoing costs with local assessment details in hand: the county's effective property-tax rate is about 1.9%, and the median annual property-tax bill is about $2,4182021.
Watch-outs
- Do not treat Franklin County as having one permit or zoning office; the town or village containing the parcel is the first stop for both questions13.
- Only about 0.6% of Franklin County soils are rated without severe limits for a conventional septic drain field, so verify an approvable design before closing15.
- RV living, temporary camping, tiny-home occupancy, private-well permitting and countywide floodplain-development requirements remain unconfirmed; ask the municipal code office and the Saranac Lake District Office before committing to a plan36.
