Window Bars for Renters: The Complete Guide
Bottom line: Renters can install window bars. The SWB Model A uses 4 small screws into the window frame — considered normal wear and tear in most jurisdictions. The bars are fully portable when you move. Here's everything you need to know.
The Legal Reality for Renters
Most renters assume they cannot modify their apartment in any way. The legal reality is more nuanced. "Modifications" that require structural changes — cutting into walls, installing new window frames, adding permanent hardware — typically require landlord permission. But installing removable hardware with small anchor screws into an existing window frame occupies a different legal category.
In most US states, courts have found that small screw holes in window or door frames constitute "normal wear and tear" rather than "damage" — the same standard that allows tenants to hang pictures without damaging their security deposit. SWB Model A installation requires 4 screws (included) into the existing window frame, not the wall. The resulting holes are smaller than a standard picture hook.
That said: always read your specific lease. Some leases include broad modification clauses that could be interpreted to cover window hardware. If in doubt, contact your landlord — most will agree to documented security improvements that also protect their property from damage claims.
Best Window Bar Options for Renters
4 small screw anchors into window frame. Fully removable. Portable to next home. Fill holes at move-out with included wood filler. Considered normal wear in most jurisdictions. $99.
Rely on spring pressure against the window channel with no anchors. No installation marks at all. Less secure — can be knocked loose by sustained pressure. Good for lower-risk windows (upper floors, windows with limited accessibility). Available from multiple manufacturers, $25–$60.
Many landlords will agree to let tenants install permanent security hardware — or will install it themselves — when the tenant can demonstrate it improves property security. In jurisdictions like New York City, landlords are legally required to provide window guards in apartments with children under 10. Check local law.
Apartment Windows That Need Bars Most
Renters often assume upper-floor apartments are safe from window entry. This is partially correct — a ground-floor apartment window faces significantly higher risk. But there are several upper-floor scenarios where window security is critical:
- Fire escape windows. Fire escapes are by definition accessible from the street or adjacent buildings. A window opening onto a fire escape is functionally a ground-floor window in terms of vulnerability.
- Adjacent rooftops. Urban buildings with neighboring flat roofs make 2nd and 3rd floor windows accessible to anyone willing to jump across.
- Ground-floor in any building. Any window at or near ground level — regardless of which "floor" the apartment is technically on — is a priority target.
