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 2025¹².

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 inspections¹¹³. 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 office¹⁴. A residential driveway onto a state highway needs a New York State Department of Transportation permit, which the property owner or a contractor requests through NYSDOT's online permitting program.¹¹ Keep permitted work accessible until the municipality has inspected and accepted it¹³.

Does Franklin County have zoning?

Franklin County has no countywide zoning code, because New York law gives zoning power to cities, towns and villages rather than counties.³ Towns and villages adopt and administer their own zoning laws.⁷⁴ 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 approval⁷. 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 description⁷. A proposed subdivision may also require municipal planning-board review where the town board has authorized that process¹⁵.

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 required¹⁶. Soil is a serious siting constraint here: only about 0.6% of county soils are rated without severe limitations for a conventional septic drain field¹⁷. That rating supports making septic feasibility a purchase contingency rather than assuming a conventional field will work¹⁷.

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 village⁷. 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 apply⁷. 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 work⁹¹⁸. A manufactured-home owner may seek installer certification, but that is not a general owner-builder exemption from permits or code compliance⁸.

Building a home in Franklin County: the steps, in order

1. Identify the parcel's town or village, then ask its code-enforcement office for the zoning map, allowed-use rules and current building-permit application¹⁷.
2. Contact the Saranac Lake District Office before finalizing the site plan so the wastewater design follows the applicable health-approval path⁵⁶.
3. If access will cross a county road, contact the Franklin County Highway Department about its driveway-structure permit before building the entrance¹⁰.
4. Submit the building application with the work location, scope, tax-map number, occupancy classification and acceptable construction documents required by the local code program¹⁹.
5. Schedule the municipality's required inspections and leave covered work exposed until it is accepted¹³.
6. Obtain a certificate of occupancy or compliance before using work for which a building permit was required¹⁸.

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 contact¹⁷. Make a satisfactory septic evaluation a contract contingency because only about 0.6% of Franklin County soils avoid a severe conventional-drain-field limitation¹⁷. 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 wooded²⁰²¹. 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 roads¹⁰. 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 $2,418²²²³.

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 questions¹⁷.
• 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 closing¹⁷.
• 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 plan⁷⁶.
