The two-family house is a classic in Brooklyn, Queens, Staten Island and the Bronx: the owner lives in one unit and rents the other, or rents both. It means shared entries, a shared yard, a shared driveway, shared walls and two sets of expectations. An owner wants to protect the building and the investment. Tenants want to feel safe and also to feel that they are not being watched. Cameras can help both if they are planned and explained properly, and cause trouble if they are not. This guide explains how an owner of a two-family house can plan cameras: what to cover, what to avoid, how to handle notice and consent, how to share access, how to deal with packages and lighting and what a sensible plan costs.
This is general information, not legal advice. Landlord-tenant and recording laws are specific. Talk to a lawyer about your lease and local rules.
1. The Short Version
| Topic | Approach |
|---|---|
| Shared exterior areas | Cameras on entries, driveway, yard and side paths |
| Inside tenant units | No cameras by the owner |
| Common hallways | Cameras allowed with care and notice |
| Notice | Tell tenants in writing before installing |
| Access | Separate codes; logs; remove when tenants leave |
| Packages | Doorbell camera and a delivery plan |
| Lighting | Motion lights on shared paths and doors |
2. Know What You Can and Cannot Cover
Exterior areas that all residents use, such as the front door, driveway, yard, side passage and rear entry, are the natural places for cameras. Interior common areas such as a shared vestibule or hallway can be covered in many cases, with notice and care. The inside of a tenant's apartment is their home. An owner should not place cameras there, and recording audio is a serious legal risk. Our guide on landlord camera rules and tenant privacy and our guide on camera laws in New York and New Jersey explain the principles. When in doubt, ask a lawyer.
3. Tell Tenants First
Give tenants written notice before installing: where cameras are, what they see, who can view footage and how long it is kept. Better yet, invite them to walk the property with you and see the views. Tenants who understand that cameras cover shared entries and not their windows or living spaces are usually supportive. Those who feel surprised can become hostile. Our guide on notice and signage explains what to say. If your lease allows, add a short clause; for existing tenants, communicate clearly.
4. Shared Entries and the Front Door
A video doorbell and a camera on the front stoop show who comes and goes. If there is a shared vestibule, a camera there can help with package theft and unwanted visitors. Make sure the tenants can see their own door's activity if they have a separate entry. Provide each household with its own account or alerts rather than a single shared login. Our local pages on security camera installation in Brooklyn and in Queens describe typical setups.
5. Driveway, Yard and Side Paths
Cover the driveway and parking, the backyard and the side passage that leads to a rear unit. These are the areas where vehicles are broken into, bikes and tools are stolen and people try back doors. A camera at the rear of the house aimed along the yard handles most of it. Keep views on your property and mask neighbors' windows. Add motion lights so cameras produce usable footage at night. Our guide on securing weak spots covers common entry points.
6. Separate Doors, Separate Codes
If you use smart locks, give each household its own code and keep a log. Do not retain a standing code to a tenant's apartment unless the lease and law allow it; use proper notice for entry. Remove a tenant's code and accounts when they move out and rekey if needed. A new tenant starts clean. Our local page on security camera installation in Staten Island explains approaches for homes with separate entries.
7. Packages
Packages are a common complaint in two-family houses. Decide where carriers leave packages: a lockbox, a protected spot in the vestibule or a locker. A doorbell camera records deliveries and thefts. Tell tenants how to report problems. In September 2026, according to Hoodline, police released surveillance images after packages with sports cards worth about $17,400 were taken from a Brooklyn residential building. Your tenants' packages will be less valuable, but the principle is the same: a clear view of the entry helps everyone.
8. Lighting and Fire Safety
Motion lights at the front door, driveway, side path and rear improve safety and footage. Keep exits clear. Do not block fire escapes, rear stairs or windows needed for egress with cameras, bars or locks. Check smoke and carbon monoxide detectors in both units and common areas. Our guide on fire escapes and rear windows explains how to balance security and safety.
9. Who Sees the Footage
Decide who can view live feeds and recordings. Owners usually control the system. Tenants may be given access to the camera at their own entry. Create a policy for how footage is shared with police and with tenants involved in an incident. Do not post footage online. Keep recordings only as long as needed. Written policies avoid disputes. Our guide on how long to keep footage explains retention.
10. Vacancies and Turnover
An empty unit is vulnerable. Between tenants, check the unit regularly, keep lights on timers and keep the doors locked. If you install a camera in an empty unit for protection, remove or disable it before the next tenant moves in and tell them. Rekey and reset codes at turnover. Photograph the condition of the unit. Clear records help with deposits and disputes.
11. Common Mistakes
- Putting cameras inside a tenant's unit.
- Surprising tenants with cameras.
- Recording audio.
- Keeping a master code without a legal basis.
- Aiming at tenants' windows.
- Blocking fire exits.
- No lighting on shared paths.
- Posting footage online.
12. Cost
Planning ranges in 2026: video doorbell, $150 to $550; four-camera home system, $1,600 to $3,800; six-camera system, $2,500 to $5,200; smart lock, $150 to $500 per door; motion lighting, $100 to $500; parcel locker or lockbox, $100 to $1,500. These are planning ranges, not quotes.
13. A Second Data Point
NYPD reported burglary down 19.5% citywide in May 2026 compared with May 2025 (NYPD). Multiple entrances still add multiple weak points. A modest camera and lighting plan protects both households.
14. Questions to Ask Your Installer
- How will you cover shared areas without recording tenants' units?
- How can each household have its own access and alerts?
- How should I notify tenants?
- How will you handle codes at turnover?
- How will you light shared paths?
- How will you keep exits clear?

15. A Hypothetical Two-Family
A Brooklyn owner lives on the first floor and rents the second. The installer places a video doorbell, a front stoop camera, a driveway camera and a rear yard camera. The owner gives the tenant a written notice, a walk-through of every view and a login limited to the front and rear entry cameras. The tenant gets a smart lock code and the owner keeps a code only for emergencies, as the lease allows. A lockbox in the vestibule handles packages. After a year, the tenant renews.
16. When a Tenant Objects
Listen. Show the views. Offer masking or adjusting an angle. Explain that cameras cover shared entries and not the unit. Put changes in writing. If a tenant still objects, a lawyer or a mediator can help. Community mediation centers in New York offer low-cost services. A camera is not worth a broken relationship if there are reasonable alternatives such as better lighting or a different mount.
17. Annual Review
Once a year, review who has access, test the cameras and alerts, update the notice and check the lease language. Replace batteries, clean lenses and trim vegetation. Ask tenants whether they have concerns. Adjust the system as needed. A short review keeps expectations aligned.
