Pick any apartment building in Chicago on a Tuesday afternoon — a courtyard walkup in Lakeview, a high-rise in Streeterville, a converted office tower in the Loop, a mid-rise in Logan Square. Within a single hour, the building's front door will see something like this. A food delivery driver. A dog walker on a recurring schedule. A friend visiting for dinner. A maintenance contractor for unit 414. A prospect on a self-guided tour. A returning resident who left their fob on the kitchen counter. An Amazon driver dropping six packages. Each one needs access on different terms. And each one is either a positive moment in the resident experience or a small friction point that ends up, eventually, in a leasing review or a renewal conversation.
For most of Chicago multifamily's history, this daily dance has been managed with a patchwork — call boxes, intercoms, fob systems, leasing-office buzz-ins, the occasional doorman in luxury buildings. The result is a building where the front door is doing five different jobs with five different tools, and where operators end up spending real staff hours on entries that should be handling themselves.
That patchwork is what's changing. The category emerging — and that Chicago operators are now investing in faster than almost any other piece of proptech — is guest access. Not access control as a fob-replacement. Not visitor management as a clipboard-replacement. Guest access as a unified system that knows the difference between a delivery, a recurring service provider, an invited guest, a contractor, and a prospect, and applies the right rule to each, automatically, with the resident in control.
Chicago multifamily fundamentals are unusually tight, and that is what's pushing operators toward guest access faster than they might in a softer market. Matthews' Q3 2025 report on Chicago multifamily found vacancy at 4.7%, well below the 8.4% U.S. average, with annual rent growth of 3.4% and every submarket recording above-average increases. The same report found Chicago's market-rate apartment development at its lowest level since 2012, with only about 11,000 units (1.9% of total inventory) under construction. Limited new supply means existing buildings are competing harder against each other rather than against new construction.

Chicago Agent Magazine's coverage of the market notes that adaptive reuse is now central to the Chicago pipeline, with downtown alone delivering 806 adaptive reuse units in 2026 and another 3,921 proposed. Adaptive reuse is, by definition, retrofit. The buildings being converted to residential are old office towers, old warehouses, old hotel stock — buildings whose front doors and entry systems were never designed for the way modern residents and their guests actually move in and out of an apartment building.
JPMorgan Chase's Chicago multifamily outlook adds another dimension. Workforce housing — buildings constructed decades ago, often without extensive amenity packages — has been a source of durable demand and durable cash flow for Chicago multifamily investors. These are exactly the buildings where guest access retrofits create the highest-leverage operational improvement: older infrastructure, steady occupancy, and renters whose expectations have been shaped by the newer buildings nearby.
The market context, in plain terms: limited new supply, an aging building stock, residents with rising expectations, and operators looking for ways to compete without major renovation. That's the exact set of conditions that produces a retrofit wave.

It's not just Chicago. Multifamily research firm Parks Associates found that nearly 72% of multifamily owners and operators plan to upgrade smart building solutions, especially access control, within the next 12 months, with retrofits driving most of that activity. Industry coverage of the Parks data notes that 70% of multifamily properties already have access control in at least one property, and that retrofitting will remain a dominant trend through 2027. Parks' own research blog frames access control as the first step on a property's broader proptech journey — the foundational layer everything else builds on.
The economic case is sharp. Parks Associates research with RealPage finds that multifamily operating expenses have surged by nearly 40% since 2019, and owners are under real pressure to protect margins. The same research frames modernized access control alongside water leak detectors and smart utility solutions as the "low-hanging fruit" of multifamily retrofits — projects with the fastest payback and the most measurable impact on both operating costs and resident satisfaction.
For Chicago specifically, the math gets sharper. A market with limited new construction is a market where existing buildings have to differentiate themselves on operations, experience, and amenity. Operators making this investment aren't framing it as a security upgrade. They're framing it as a guest experience upgrade — a property differentiation upgrade — with the security and operational wins arriving as second-order benefits.
Access control as a category is about thirty years old. It started as a fob-and-keypad replacement for physical keys and grew into a broader system of credential management. That's a useful capability, but it's not the same thing as guest access.
The difference is the scope of the problem. Access control answers a narrow question — is this credential authorized to open this door right now. Guest access answers the harder one — who is this person, what category do they belong to, what should they be allowed to do, who authorized them, for how long, and how does the resident stay in control of all of it. A resident's standing weekly cleaning appointment and a one-time food delivery are both "people who don't live here who need to get in." A pure access control system handles them with the same logic. A guest access system treats them differently because they are different.
That distinction matters because the work filling up a Chicago property manager's inbox isn't "we need more fobs." It's "the dog walker can't get in." "The delivery driver buzzed every unit at 9 p.m." "My contractor is here and the leasing office is closed." "My parents are visiting from Indianapolis this weekend and I want them to have access." Every one of those is a guest access problem. None of them are solved by issuing more fobs.
A guest access platform built for the realities of Chicago multifamily has to deliver a few outcomes in parallel.
It has to recognize categories of people, not just individuals. A resident's recurring dog walker should have durable, time-bounded access for the duration of that arrangement. A food delivery driver should get single-use access at the door. A family member visiting for the weekend should have a credential that expires Sunday night. A maintenance contractor should have a working window with a clear audit trail. A self-guided tour prospect should have access that activates only at a specific scheduled time. The system should know the difference and apply the right rule, automatically, every time. The fewer times a category mismatch ends up on a person's desk, the better the system is working.
It has to put the resident in control. The category that grows fastest in any portfolio is "guests authorized by residents directly" — and it's exactly the category most legacy systems handle worst, because they were designed around staff as the gatekeeper. A resident should be able to authorize their own guest in seconds, from their phone, without calling or texting the leasing office. The platform's job is to support the resident's choice, not to gate it. The buildings that get this right see fewer support requests, fewer late-night calls about a friend stuck downstairs, and noticeably better renewal conversations.

It has to take work off the operator's plate. Self-guided tours, package deliveries, recurring service providers, weekend visitors — these are entries that should not require a property manager's attention. When the system handles them automatically, staff time gets returned to the work that actually retains residents and closes leases. The Parks Associates data on multifamily margin pressure makes this concrete: the operators who recover hours of staff time per week from front-door interruptions are the ones with room to absorb the cost increases hitting the rest of the business. In a high-occupancy, high-renewal-rate market like Chicago, that recovered time tends to flow directly into resident experience and retention work.
It has to produce an audit trail. Every entry, by every category of person, needs a timestamped, exportable, queryable record. Not for paperwork's sake — for the moments when something goes wrong and the operator needs to reconstruct what happened, when an insurer asks how access was managed, when a resident asks who came to their door on Tuesday afternoon. Modern guest access turns those questions into queries instead of investigations.
And it has to retrofit cleanly. Most multifamily buildings in Chicago were not built around modern access infrastructure — and the city's adaptive reuse pipeline means a growing share of "new" units are landing in old buildings whose entry systems are even further behind. The decisions that matter are about how new credentials and rules layer onto existing doors, gates, and intercoms — not about tearing the building out and starting over. The Parks Associates research is clear that the operators winning right now are the ones who can deploy without major renovation work, which makes a properly designed retrofit one of the highest-leverage capital decisions a Chicago property has available to it this year.
Step back from the operational mechanics and a bigger pattern emerges. The front door of a multifamily building is no longer just a security boundary. It is the most-used touchpoint in the resident experience. Every time a dog walker, food delivery, friend, or family member tries to get in, the building either makes that easy or makes it hard. Multiplied across hundreds of residents and thousands of guests per month, those small moments add up to a real signal — about how the building works, how much it respects the resident's time, and whether it feels like home or like a checkpoint.
Chicago operators who treat the front door as a strategic surface are seeing measurable returns. Lower friction at entry correlates with better leasing reviews and stronger renewals — and Chicago's elevated renewal rates, paired with limited new supply, mean every renewal conversation matters more than it would in a looser market. Self-service guest authorization correlates with lower staff workload and fewer lockout incidents. Audited access correlates with lower incident-response cost when something does go wrong. None of this is hypothetical anymore. The operators who started their retrofits two and three years ago have the data, and that data is part of what's pulling the rest of the Chicago market forward.
The category name for this is guest access. Not access control as a generic security upgrade. Not visitor management as a clipboard replacement. Guest access as a system designed around how Chicago residents actually live and how Chicago operators actually run buildings.
The path forward is straightforward, but it does require sequencing.
Map the building first. Where are the entry points? Which doors today are controlled by keys, fobs, intercoms, or nothing at all? Where do the friction points live — package room, garage, side entrances, amenity spaces, courtyard gates? In Chicago's older building stock, this audit often surfaces 30 to 50 percent more entry points than the operator initially counts. The audit takes a week and shows where retrofit dollars produce the most leverage.
Categorize the people next. Who actually enters the building each day? Residents, their guests, recurring service providers, vendors, delivery drivers, contractors, prospects, inspectors. Each category gets its own access rule. The clearer the categorization, the more configurable and useful the platform becomes — and the cleaner the audit trail it generates.
Evaluate platforms against the work they take off your team's plate. The right question isn't "does this support mobile credentials" — most platforms claim that. The right questions are: how many guest entries can a resident self-authorize without involving staff, how many categories of visitors can the system distinguish automatically, how clean is the audit trail, and how cleanly does it retrofit into the building you actually have. In a Chicago market where adaptive reuse is the dominant new-supply story, retrofit-friendliness is not a nice-to-have — it's the deployment model.
Plan for the resident experience from day one. The retrofit succeeds when residents notice that getting their guests, deliveries, and service providers through the front door has become invisible — and when staff notice that the entries they used to handle one at a time now handle themselves. Both signals show up in the data within the first quarter of a properly executed deployment.
The technology has caught up to the operating model. Cloud-based guest access can apply different rules to different categories of people, give residents direct control over their own visitors, support staff without replacing them, generate the audit trail every operator now needs, and retrofit into existing Chicago buildings without major renovation. Gatewise has been working with multifamily operators on exactly this kind of guest access architecture, and the pattern that's emerging is consistent. The operators who move first treat the front door as a strategic asset. The operators who wait keep treating it as a liability.
Chicago is one of the tightest multifamily markets in the country right now, with limited new construction and operators competing harder than ever on resident experience. The retrofit window for guest access is open, and the data on who's moving through it is already being collected by the operators who got there first. The right time to start was a while ago. The next-best time is the next quarter.
