An in-law suite, finished basement apartment, garage conversion or backyard cottage adds living space and sometimes income. It also adds a second household on the same lot. Two households share a driveway, a yard and maybe a front door, and each wants security and privacy. Where cameras go and who sees what are the sort of questions that can strain family relations or a landlord-tenant relationship if they are not settled up front. This guide explains how to plan cameras for an in-law suite or accessory unit: how to cover shared areas, how to respect the occupant's privacy, how to handle access codes and notice, and what a sensible plan costs.
This is general information, not legal advice. Rules about accessory units, rentals and recording vary. Check local requirements and talk to a lawyer about a rental.
1. The Short Version
| Area | Approach |
|---|---|
| Shared driveway/walkway | Cameras covering approaches and parking |
| Unit entrance | Doorbell or door camera aimed only at the door |
| Inside the unit | No cameras by owner in a rented or lived-in unit |
| Access | Separate codes and logs |
| Privacy | Written agreement on what cameras see |
| Lighting | Motion lights on shared paths and the unit entrance |
| Notice | Tell the occupant before installing |
2. Two Households, One Lot
Whether the occupant is a parent, an adult child or a paying tenant, the unit is their home. They expect privacy, and they also expect safety. The best setup covers the shared outdoor areas and the main approaches, protects the occupant's privacy and gives each household control over its own door. Our guide on camera placement explains how to plan views, and our guide on camera laws in New York and New Jersey explains why aim and notice matter.
3. Shared Areas
Cover the driveway, front walk, side path and any shared yard or parking. A camera aimed at the street side of the lot shows who approaches. A camera in the back covers the yard and rear doors. Both households can have access to those views. Agree on who can view and save footage. Keep the field of view on shared and exterior areas. Our local pages on security camera installation in Staten Island and residential camera installation in Jersey City describe typical setups.
4. The Unit Entrance
The door to the suite should have its own lock and, if the occupant wants it, a video doorbell or door camera that the occupant controls. If the owner installs it, aim only at the door and the immediate approach, and tell the occupant what it sees. Do not aim into windows. Do not use cameras to monitor the occupant's visitors beyond what the occupant has agreed to. An occupant who feels watched will not feel at home.
5. Inside the Unit
Owners should not install cameras inside a unit that someone else lives in. That includes a tenant, a relative or an adult child. Recording inside a person's home without their knowledge raises serious legal and personal problems, and recording audio can be illegal. If the unit is vacant, a camera inside can protect it, but remove or disable it before someone moves in and tell them. For a rented unit, check the law with an attorney. Our guide on landlord camera rules and tenant privacy explains the issues.
6. Access Codes and Locks
Use a smart lock or keypad with a unique code for the occupant and temporary codes for visitors, cleaners or contractors. The occupant controls their own code. The owner should not have a standing code to enter the unit except as the lease or family agreement and the law allow. A log of entries helps the occupant too. A keyed backup is wise. Our local pages on smart locks in Brooklyn describe options.
7. Written Agreement
Put expectations in writing, even with family. The agreement should say where cameras are, what they cover, who can view recordings, how long recordings are kept and what happens if the arrangement ends. For tenants, a lease clause is common. A written note prevents misunderstandings and protects relationships. Our guide on notice and signage explains what to say.
8. Lighting and Paths
A shared path to the unit should be lit. Motion lights help the occupant get home safely and improve camera views. Aim lights so they do not shine into windows. Keep steps and handrails in good condition. Our guide on lighting for night cameras explains placement.
9. Basement and Garage Units
Lower-level units have specific weak points: window wells, rear doors, exterior stairwells and sometimes shared mechanical rooms. Cover the exterior stairs and the entrance with a camera. Secure window wells with covers that do not block emergency exit. Keep egress clear. Check local rules for accessory units, which often require safe exits and working alarms. Our guide on basement apartment entrances covers more.
10. Packages and Deliveries
Deliveries for two households can get mixed up. A doorbell camera at each entrance helps. Agree where carriers leave packages and who picks them up. A lockbox or locker shared by both units may help. Our guide on porch pirates explains prevention. In September 2026, according to Hoodline, police released surveillance images after packages containing sports cards worth about $17,400 were taken from a Brooklyn residential building. Few packages are worth that much, but a clear record of who took what helps in any dispute.
11. When the Relationship Changes
Family arrangements end, tenants move and in-laws pass away. Plan for it. Change codes, remove accounts, review camera settings and update the agreement. If the unit becomes a rental, review local rules and consider consulting an attorney. Good records and clear boundaries make transitions easier.
12. Common Mistakes
- Installing a camera inside an occupied unit.
- Not telling the occupant about cameras.
- Aiming cameras into the unit's windows.
- Keeping a master code for entry.
- No written agreement.
- Ignoring lighting on shared paths.
- Blocking egress.
- Recording audio.
13. Cost
Planning ranges in 2026: video doorbell for the unit, $150 to $550; two or three cameras covering shared areas, $900 to $2,400; four-camera system, $1,600 to $3,800; smart lock, $150 to $500; motion lighting, $100 to $500; additional account setup, usually minimal. These are planning ranges, not quotes.
14. A Second Data Point
NYPD reported burglary down 19.5% citywide in May 2026 compared with May 2025 (NYPD). Lower-level and rear units are often the quietest parts of a property, so entry points matter regardless of the trend.
15. Questions to Ask Your Installer
- How will you cover shared areas without recording inside the unit?
- Can each household control its own door camera and lock?
- How should we handle access codes and logs?
- What should a written agreement include?
- How will you light the shared path?
- How will you handle egress at the entrance?

16. A Hypothetical Arrangement
A Staten Island homeowner converts the basement into an in-law suite for her mother. The installer adds a driveway camera and a rear-yard camera that both households can view, a door camera at the suite's separate entrance that her mother controls, and a smart lock with unique codes. A motion light covers the side path. No camera is installed inside the suite. They write a one-page agreement that lists camera locations, who can view footage and how long it is kept.
17. Talking It Through
The best security plan for a second unit starts with a conversation. Walk the property together. Ask the occupant what makes them feel safe and what would feel intrusive. Show them every camera view. Agree on changes in writing. People accept cameras that protect them and respect their space. They resent cameras that watch them. Respect is the foundation of a system that lasts.
18. Moving Out and Moving In
When an occupant leaves, treat the unit like a new home. Change codes, remove their accounts from locks and cameras, check windows and doors, and walk the shared areas together with the next occupant so they know what is recorded. Delete any footage you no longer need to keep. A clean handoff protects both households and avoids surprises about what the cameras see.
