The Town of Southeast, in Putnam County, New York, has its own zoning code1 and requires a building permit and certificate of occupancy from the Town Building Inspector before most construction2.

Does the Town of Southeast, NY have zoning?

Yes. The Town of Southeast adopted its own zoning chapter through the Town Board1, and the town is divided into zoning districts6. Putnam County does not zone: New York gives counties no zoning power12, and the county has no countywide zoning code5. Lot size, lot coverage and building height all depend on the district your parcel sits in131415. The Building Department publishes a zoning map and a use and setback regulations page, so find your parcel's district there first11. Short-term rentals are allowed with a conditional use permit in any legal dwelling unit, a rule added in 20259. We could not confirm the town's rules for RVs, tiny homes, manufactured homes or temporary camping; the code does prohibit a tent used as a dwelling, so ask the Building Department before planning to live on a lot while you build.

Do you need a building permit in the Town of Southeast, and who issues it?

Yes. No building or structure may be constructed, enlarged, moved or structurally altered in the Town of Southeast until the Building Inspector approves an application and issues a building permit with a certificate of occupancy27. The Town of Southeast Building Department says a permit is also needed for most home improvements, including sheds, pools and accessory apartments11. Fees follow a Town Board-adopted schedule, and the Town Clerk has copies10. Statewide, New York's Uniform Code requires permits and inspections for covered work1617. Agricultural structures are treated separately: temporary structures that support farm uses inside a listed agricultural district are carved out18. We could not confirm any owner-builder exemption in the town's code, so ask the Building Department. The department's rules apply inside the town; for land elsewhere in the county see the Putnam County page.

How do septic permits work in the Town of Southeast?

Septic permits for Southeast addresses are issued by the Putnam County Department of Health, not the Town Building Department. Repair or replacement of any septic component needs prior Health Department approval19, and the department requires soil test pits or percolation tests witnessed by its engineering staff20. A septic repair permit carries a $150 fee19. Because part of Putnam County sits in the New York City watershed, the Health Department decides whether a project is handled by the county alone or reviewed jointly with NYC DEP8. Indoor plumbing wastewater must go to an approved septic system, so there is no off-grid shortcut for a house with bathrooms21. Southeast's own code includes a septic inspection program, but we could not confirm a town septic-permit rule, so call the county health department's engineers first. Expect a site evaluation, since only a small share of the county's soils rate as not limited for conventional drain fields22.

Who handles wells, driveways and floodplain permits in Southeast?

Private wells need a permit from the Putnam County Department of Health before drilling begins4. A driveway onto a state highway needs a New York State Department of Transportation permit23; the town code has a driveway-permit section, but we could not confirm its requirements, so ask the Building Department about town roads. Development in FEMA-mapped flood hazard areas is subject to local floodplain development permits24, and the town has a floodplain chapter whose operative requirement we could not confirm.

Building a home in the Town of Southeast: the steps, in order

  1. Find your parcel's zoning district and its setbacks on the town's zoning map and use and setback page11.
  2. Call the Putnam County Department of Health engineers at (845) 808-1390 about soil testing, septic and well approval20.
  3. Apply to the Town of Southeast Building Department for a building permit; it may refer the application to the Zoning Board of Appeals, the Planning Board or the Architectural Review Board11.
  4. Build with inspections at the stages the Building Department requires, then obtain a certificate of occupancy before use7.

What stays with Putnam County, and what to check before you buy in Southeast?

Septic, wells and subdivision health review stay with the Putnam County Department of Health325. Putnam County's effective property tax rate is 2.2%, with a median bill of $10,001 a year2627. About 90% of the county is wooded28, so access and tree clearing are worth checking on site. For land outside the Town of Southeast, see the Putnam County page.

Watch-outs

  • We could not confirm whether Southeast allows living in an RV, tiny home or manufactured home on a lot, or what rules apply to temporary camping; ask the Building Department at 845-279-2123 before you buy11.
  • The numeric lot-size, coverage and height limits sit in district tables we could not read, so confirm them for your district with the Building Department before relying on a parcel13.
  • Do not assume a septic permit comes from the town: the Putnam County Department of Health approves septic systems and wells3.
