New York has no state home-improvement-contractor license, but that alone does not mean you can build a new house yourself1. Ask your local building department which local licensing and trade rules apply to your work2. No New York county is listed as having no residential building-permit requirement3.
Does New York have an owner-builder license exemption?
New York's confirmed rule covers home improvements; it does not give blanket permission to build a new home without licensed help.
New York's confirmed rule covers home improvements; it does not give blanket permission to build a new home without licensed help1. New York State does not license home-improvement contractors, so you have no state license in that category to get1. Counties and municipalities can set their own contractor or trade licensing rules1.
Before you budget to do the work yourself, ask your local building department whether you can act as your house's contractor2. Be clear that you mean new construction, rather than home improvements alone. Ask which tasks you can do yourself and which need licensed trades.
Who decides whether you can build your own home in New York?
Your local building department can help you find the forms and code requirements for your project.
Your local building department can help you find the forms and code requirements for your project2. Outside New York City, the Uniform Code applies automatically in cities, towns and villages5. A local government cannot opt out of the Uniform Code5. New York City has its own construction code, so the statewide Uniform Code process described here does not cover your city project5.
You may need local licenses even though New York has no state home-improvement license1. New York's Department of State names New York City, Buffalo, Suffolk, Nassau, Westchester, Putnam and Rockland as examples with local licensing requirements1. Ask your building department which licensing office should review the work you plan to do.
What does a New York owner-builder building-permit application need?
Plan to get a building permit for a new house outside New York City under the state's code rules.
Plan to get a building permit for a new house outside New York City under the state's code rules4. Doing the work yourself does not give you an established exemption from building permits or inspections1. Your application needs the work location, scope, tax map number, street address, occupancy classification and acceptable construction documents6.
Your construction documents may need site plans, structural details, building-system information and Energy Code compliance information6. You may also need documents from a licensed architect or professional engineer6. Ask your local building department for the application checklist and fee schedule before you pay for plans. Ask specifically whether the drawings you plan to submit need a professional seal.
Are any New York counties exempt from house building permits?
No New York county is listed as having no residential building-permit requirement.
No New York county is listed as having no residential building-permit requirement3. The county totals list 61 as requiring residential building permits and 1 as requiring them in limited cases3. Those county categories describe unincorporated land; they do not give you a separate answer for every city address3.
Both Lewis County and Franklin County are in the group that requires building permits3. Washington County is the limited-case entry, but its stated exception covers a small detached shed, not a new house3. Check that distinction when you compare land for a house. New York's listed exceptions for accessory structures do not exempt house building4.
What inspections does an owner-built house need in New York?
Outside New York City, construction covered by a building permit needs inspections under the state's code rules.
Outside New York City, construction covered by a building permit needs inspections under the state's code rules4. Stages that apply include foundations, slab preparation, framing, building systems, energy compliance and final inspection4. As the permit holder, you must tell the authority when work is ready4. Keep your work accessible and exposed until it is inspected and accepted4.
Ask your building department for the inspection sequence before you schedule concrete or close walls. New York's minimum rules exempt owner-occupied homes from regular periodic inspections, but you still need construction inspections4. That periodic-inspection exception does not let you skip inspections while you build your house4.
When can you move into a house you built yourself in New York?
Outside New York City, you need a certificate of occupancy or compliance before using or occupying a covered building.
Outside New York City, you need a certificate of occupancy or compliance before using or occupying a covered building4. The authority must inspect and find that the building meets code before issuing your certificate4. Supporting records may include special-inspection reports, flood-hazard certifications and Energy Code test results4.
A temporary certificate has conditions; it does not automatically let you live in unfinished construction4. Temporary approval covers specified portions for a specified period, with conditions for safe occupancy and completion4. Ask your building department what you must finish before you can get any move-in approval. Before you buy land, ask separately about work you can do yourself, building-permit documents, inspections and the final occupancy certificate.

- A qualifying shed exception does not exempt your new house from New York's building-permit rules4.
- New York City retains its own construction code5.
- Living in your own home does not remove your construction inspection duties in New York4.
