Security Screens for Los Angeles Apartment Buildings: What Owners and Property Managers Need to Know

Bars destroy your rents. There is a better answer, and the city may help fund it.

Security screens are one of the few upgrades that improve tenant safety, reduce turnover pressure, and still let a unit breathe. For multifamily properties, the right product is a stainless steel security screen for Los Angeles buildings that meets emergency escape requirements and can be standardized across every ground-floor opening. Tashman Home Center has installed windows, doors, and screens across Los Angeles since 1961 using trained in-house installers.

That covers the what. The rest of this guide covers the part most owners get wrong.

Why Ground Floor Units Carry Almost All of the Risk

In most Los Angeles apartment buildings, the security problem is not the building. It is a handful of specific openings.

Walk any dingbat in Palms, any courtyard building in Hollywood, or any 1920s fourplex in Hancock Park and the pattern repeats. The vulnerable openings are the ones nobody can see from the street:

• Ground floor bedroom windows facing an alley or a side yard

• Units above tuck-under parking, where a carport gives someone a place to work unobserved

• Sliding patio doors opening onto a shared courtyard that anyone can walk into

• Rear service doors, laundry room doors, and trash enclosure access points

•  First-floor windows screened from the sidewalk by mature landscaping

Los Angeles reported residential and commercial burglaries down more than 30 percent in 2026 compared with 2025, according to LAPD figures cited by the Mayor's office. That is real progress. It does nothing for the one unit in your portfolio that gets hit, and a break-in to an occupied unit becomes a habitability conversation, an insurance conversation, and sometimes a vacancy.

Those openings are where professionally installed security screens earn their cost, and they are usually a small fraction of the total openings in the building.

The Code Detail That Decides Whether Your Project Passes

Understand this rule before specifying anything, because it is where most multifamily security projects fail inspection.

Any device placed over an emergency escape and rescue opening must release from the inside without a key, a tool, special knowledge, or more force than the window itself normally takes to operate. The California Residential Code states that bars, grilles, covers, and screens are permitted over these openings only if the minimum net clear opening is preserved and the device is "releasable or removable from the inside without the use of a key, tool, special knowledge, or force greater than that required for the normal operation of the escape and rescue opening."

Sleeping room windows are what matter here. In practice:

• A fixed grille bolted over a bedroom window is a problem

• A padlocked security gate on a bedroom window is a serious problem

• A security screen with an interior quick-release mechanism is the compliant path

Which section governs your building depends on occupancy classification and the code cycle in effect, so confirm the requirement with LADBS before ordering. Any qualified installer should raise this before you do. If a bid does not mention egress, that tells you something about the bid.

This is also the clearest argument for choosing security door screens over traditional bars in rental housing. Screens can be engineered to release from inside. Welded bars generally cannot.

Security Screens vs. Security Bars in Rental Housing

Both products resist forced entry. Only one belongs on a rental property, and the differences show up in your operations more than in your architecture.

Where stainless security screens win:

• Emergency egress. Screens can be built with an interior quick release. Welded bars usually fail this test without an expensive retrofit.

• Leasing and rents. Fine stainless mesh reads as an ordinary window screen from the sidewalk. Bars are visible from across the street and signal a high-crime property to every prospect who drives by.

• Insect protection. The mesh doubles as an insect screen. Bars leave you buying screens separately.

• Building appearance. Screens blend with existing window frames. Bars permanently change the facade.

• Corrosion resistance. 316 marine-grade stainless holds up in salt air. Painted steel bars near the coast start bleeding rust down the stucco within a few seasons.

That last point matters for any Santa Monica, Venice, or Marina del Rey property. Repainting occupied elevations to hide rust stains becomes a recurring line item, and it is entirely avoidable.

Standardize One Specification Across the Building

This is the single largest cost lever in a multifamily retrofit, and most owners miss it.

When every ground floor opening gets the same mesh, the same frame color, the same lock, and the same hinge, three things happen. Fabrication runs cheaper per unit. Future replacement becomes a phone call instead of a site visit. And the building reads as intentional rather than as a series of one-off tenant requests.

Practical guidance for setting the standard:

• Choose one powder coat color that matches or disappears against your existing window frames

• Specify one mesh grade so replacement panels stay interchangeable

• Keep one hardware set so maintenance staff stocks one set of spares

• Document the specification in writing and reuse it on the next building

Vintage Los Angeles stock complicates this in one way. Courtyard buildings, dingbats, and prewar fourplexes rarely have consistent opening dimensions, even within the same building, so stock sizes will not fit. Every panel has to be measured and fabricated to the opening, which is why Tashman's custom security screen and window screen work is measured on site rather than ordered from a catalog. That same custom fabrication capability was the subject of recent coverage of Tashman's screen door work.

What Vista Security Screens Bring to a Multifamily Project

Tashman installs Vista Security Screens, and the specification matters more in multifamily than in single-family work because you are buying the same product dozens of times.

The relevant details for an owner or asset manager:

• 316 Marine Grade High Tensile Stainless Steel Security Mesh. The 316 alloy contains molybdenum, which is what separates it from cheaper 304 stainless in coastal air. On the Westside, that is a durability decision, not a marketing one.

• Independently tested. Knife shear testing per AS 5041-2003, forced entry and impact testing per AAMA 1304, and salt spray corrosion testing per ASTM B117-16 and AS 2331.0-2006.

• A patented screen tensioning system. Tension is what keeps mesh from being pushed out of the frame, and it is the part cheap screens get wrong.

• A ten-year warranty on mesh and sash panels, and one year on hardware. That split tells you the mesh and frames are effectively a permanent asset, while hinges, closers, locks, and rollers are the wear items you should budget to service.

For capital planning, treat the screens as a long-life envelope component and the hardware as a maintenance line. That framing matters for the next section.

How Los Angeles Owners Can Fund the Project

This is the part almost nobody in the security screen business talks about, and for RSO properties it changes the math entirely.

The Los Angeles Housing Department runs a Capital Improvement Program that lets owners of rent-stabilized buildings recover a portion of qualifying improvement costs through a monthly tenant surcharge. Security upgrades, doors, and windows appear on the department's list of eligible improvement categories.

To qualify, an improvement must:

• Primarily benefit the tenants

• Have a useful life of five years or more

• Be permanently affixed or relatively immobile

• Be completed within 12 months of the application

• Not be routine maintenance or repair

A properly installed security screen program clears all five comfortably. The 10-year mesh warranty alone speaks to the useful life test.

The published formula splits approved costs evenly and works in three steps:

1.  Multiply the total approved cost by 50 percent
2. Divide that figure by 60 months
3. Divide again by the number of benefiting units

The result is the monthly surcharge per unit. It is capped at $55 per unit per month and collected until the approved total is recovered, up to a maximum of 72 months.

Worked example. If a security screen program across the ground floor of a building comes to $36,000 in approved cost and 12 units benefit, the calculation is $36,000 × 50 percent = $18,000, divided by 60 months = $300 per month, divided by 12 units = $25 per unit per month. That sits comfortably under the $55 cap.

Two cautions. Owners have 12 months after completion to apply, and applications require contractor invoices, contracts, and proof of payment. Confirm current rules and eligibility directly with LAHD before relying on any pass-through, because terms change and every building differs. Tashman can provide the itemized documentation the application requires.

Phasing the Work Across Occupied Units

Retrofitting occupied units is more of a scheduling problem than a construction problem. Security screen installation is dry work with no demolition. A typical approach:

1.  Measure every target opening in one pass and lock the specification
2. Fabricate the full run so panels arrive together
3. Give tenants written notice consistent with your lease and California entry requirements
4. Install by stack or by elevation rather than randomly, so crews are not crossing the property repeatedly
5. Walk each unit with the tenant and demonstrate the interior release before leaving

Most openings take well under an hour once the panel is on site, so tenant-facing time stays short. That matters when you are coordinating access across a dozen households. Tashman uses trained in-house installers rather than subcontractors, so the crew that measures your building is the crew that returns to install it.
