Want room to breathe on the North Shore but unsure what you can build or maintain? If you are eyeing Old Brookville, Brookville or Upper Brookville, you are looking at true estate country with privacy, larger parcels and a different set of rules. You will learn how acreage and zoning work here, what accessory structures are common, the lifestyle tradeoffs to expect, and a clear checklist to vet any property. Let’s dive in.
Acreage and zoning at a glance
Separate villages, distinct codes
Old Brookville, Brookville and Upper Brookville are separate incorporated villages in the Town of Oyster Bay. Each sets its own zoning map and code, so rules can change from one street to the next. The district name on the zoning map determines minimum lot size, frontage, setbacks and permitted uses. Always verify the exact zoning designation and the most recent code text for the specific parcel.
Typical lot sizes
This area is known for estate-scale living. You will see parcels from fractions of an acre to 5 or more acres, with many neighborhoods featuring 1 to 5-plus acre lots. Several districts require minimum lot sizes of 1 or 2 acres, and some require even more. Smaller lots exist, especially historic parcels that predate current rules.
Non-conforming lots and structures
Some properties were created before today’s zoning. These are often legally non-conforming and can have limits on expansion, rebuilding or subdivision. Confirm non-conforming status early because it affects what you can change after purchase.
Setbacks, coverage and subdivision
Villages regulate how far structures must sit from property lines, how much of the lot can be covered by buildings and pavement, and how new lots can be created. Planning board review and public hearings are common for subdivisions. A large parcel is not always subdividable unless it meets current standards for area, frontage and shape.
Accessory structures: what to know
Common estate features
Many Brookville-area estates include one or more of the following:
- Detached garages or carriage houses
- Guesthouses or accessory apartments
- Barns, stables, riding rings and paddocks
- Pools, pool houses and expansive terraces
- Tennis or sport courts and long driveways
- Greenhouses, sheds, generator houses and solar arrays
- Fencing, gates and formal entries
Permits and approvals
Most projects begin with a building permit application to the village. Some proposals, like a new guesthouse, equestrian facility or unusual structure, can require planning board or architectural review. If a plan does not meet a dimensional rule, you may need a variance from the Zoning Board of Appeals. County or state permits can also apply to wetlands, driveways on county roads, or sewer connections.
Limits to check before you plan
- Permitted vs special-permit uses: Some accessory uses are allowed by right, while others need a special permit or variance.
- Size and footprint: Codes may cap square footage of an accessory building or limit combined roofed area.
- Location and setbacks: Placement is often restricted near lot lines, wetlands or easements.
- Height: Barns and stables can have distinct height limits; confirm any vertical caps.
- Number of units: Rules can control whether a guesthouse is a separate dwelling, whether it can be rented, or if it counts as an accessory apartment.
- Impervious limits: Paved areas, courts and patios may be limited by lot coverage caps.
- Animal keeping: Villages often regulate the number of horses or large animals per acre and require stable management plans.
- Pool and fence rules: Pools typically require permits and safety fencing to current code.
- Utilities and wastewater: A guesthouse or apartment can trigger septic upgrades or sewer requirements. Confirm service capacity and approvals.
Lifestyle tradeoffs in the Brookvilles
Privacy and maintenance
Large parcels deliver privacy and a park-like feel. They also bring higher upkeep: mowing, tree care, snow removal on long driveways, pool service, gate and fence maintenance, and drainage management. Plan for ongoing landscape and property management costs.
Water, sewer and systems
Many homes connect to municipal water and, where available, county sewer systems. Some properties rely on private wells and septic systems, especially on older or outlying parcels. If you plan a guesthouse or larger accessory use, you may need wastewater upgrades or engineered solutions.
Environmental and site limits
Wetlands, floodplains, steep slopes and specimen trees can limit where you can build. Conservation easements or deed restrictions can also affect additions, tree removal or subdivision potential. If you add impervious areas like courts or long drives, stormwater controls may be required.
Equestrian considerations
Stables and paddocks are common on larger parcels, especially in Upper Brookville and Old Brookville. Verify allowances for the number of animals per acreage, stable setbacks and manure management requirements. Consider access to veterinarians, farriers and riding facilities if equestrian use is a priority.
Commute, services and response times
With estate-scale lots, you trade walkability for space. Check drive times to major routes and Long Island Rail Road stations, and confirm proximity to daily services and medical care. Emergency response can vary in low-density areas, so review local fire protection, hydrant locations and hospital access.
Schools, taxes and insurance
Parcels can fall within different school districts, and district assignment influences tax bills. Nassau County property taxes are typically high relative to many regions, so review the current tax bill and all taxing districts. Pools, outbuildings, equestrian facilities and larger homes can increase insurance needs; get quotes and consider umbrella coverage.

How to approach your search
Start with clarity on how you want to live. Make a short list of must-haves like acreage, guesthouse potential, or equestrian use. Then confirm the zoning district, any non-conforming status and environmental factors before you fall in love with a property.
Line up the right team early. A surveyor, engineer and attorney can save time by scoping setbacks, stormwater, septic and title items up front. If you need to sell before you buy, coordinated prep and presentation can help you capture top value so you can move quickly on the right Brookville property.
