US downtowns are carrying record office vacancy while housing stays scarce, and cities are actively courting conversions.
Converting office buildings into coliving in the United States has moved from a fringe idea to a serious asset-repositioning play, driven by structurally high vacancy in older commercial stock and a persistent shortage of attainable rental housing in major metros.
The opportunity is real but uneven: it works best on the right floorplate, in the right submarket, with a sponsor who understands both the construction reality and the operating model of shared living.
This is not a cosmetic refit. A credible conversion rethinks the building as a home for dozens of residents, and the projects that pencil are the ones where the bones of the building cooperate.
Older Class B and C office towers in central business districts can trade at prices that make residential and coliving conversion viable, especially where cities offer incentives to bring downtowns back to life.
Conversion is governed city by city. Several major cities have introduced office-to-residential incentive programs, zoning overlays, or tax abatements. Zoning, building code, and egress requirements are the gating items, so the specific municipality decides feasibility.
Rules vary by city and change over time. Treat this as a starting point and confirm the current requirements with the relevant local authority before you underwrite a deal.
Across many US downtowns, a category of aging Class B and Class C office buildings is effectively stranded: tenants have left for newer space or hybrid work, and the cost to re-lease as office keeps rising. For some of these assets, residential conversion is the only path back to a productive use, and coliving is often the residential format that fits best because it maximizes rentable rooms from deep, boxy floorplates.
Coliving suits conversions because it embraces shared kitchens, lounges, and amenity space rather than fighting the floorplate. Where a conventional apartment conversion struggles to reach enough windows for every unit, a coliving layout can place private bedrooms along the perimeter and pull cooking and social space into the core.
Demand support comes from renters priced out of studios and one-bedrooms in expensive metros, students and early-career professionals, and people relocating who want a furnished, community-oriented landing spot. The strongest markets combine high housing cost, a young renter base, and a stock of convertible buildings.
In the US, land use and building codes are set locally, so the change from commercial to residential use varies significantly by city and even by zoning district. Some jurisdictions have introduced streamlined conversion pathways or adaptive-reuse provisions, while others require a full rezoning or variance process. Treat every point here as general and verify the specifics with local planning authorities and qualified land-use counsel before you underwrite anything.
Beyond zoning, residential occupancy triggers a different set of life-safety and habitability requirements than office use: egress, fire separation, natural light and ventilation, and accessibility standards can all change. Coliving may also raise definitional questions about how the local code treats shared kitchens, bedroom counts, and what constitutes a dwelling unit, which is exactly where early conversations with the authority having jurisdiction pay off.
The practical lesson is to run the regulatory diligence in parallel with the design and financial work, not after it. A building that looks perfect on a spreadsheet can be sunk by an unfavorable zoning read or an egress problem, so confirm the path to a legal residential use early and in writing.
Not every office building wants to be housing. The single biggest driver is the floorplate: shallower floor depths from window to core make it far easier to give every bedroom natural light, while very deep plates leave dark interior space that is hard to use as habitable rooms. Older buildings with operable windows, punched window openings, and modest floor sizes often convert more gracefully than large-plate modern towers.
The mechanical, electrical, and plumbing story matters just as much. Residential use means far more plumbing stacks, individual metering questions, and ventilation than an office ever needed, and the feasibility often turns on whether risers and vertical chases can be added without gutting the structure. Ceiling heights, structural bay spacing, and the condition of the facade and roof all feed into cost.
Use the checklist below as a first-pass screen, but confirm every item with a design and engineering team on the specific building.
A conversion pro forma has to hold together on three fronts: the all-in cost to buy and convert, the revenue the operating coliving asset can produce, and the exit or hold value. Coliving typically lifts revenue per square foot versus conventional apartments because you are renting more rooms and often including furniture, utilities, and services, but it also carries higher operating intensity, so both sides of the ledger move.
Acquisition basis is often the make-or-break variable. Distressed or repriced office can create room in the budget for the heavy conversion spend, whereas a building bought at an office valuation that never materialized will struggle. Construction cost is dominated by the MEP scope, facade and window work, and bringing the building up to current residential code, so early engineering input is worth more than a polished spreadsheet.
Illustrative only: on a mid-size conversion you might model an acquisition in the single-digit millions, a conversion budget of a similar order, and a stabilized coliving operation targeting occupancy in the low-to-mid nineties percent. These are placeholder figures to show the shape of the model, not benchmarks; every real deal needs its own underwriting with local cost and rent inputs.
Everything Coliving works with owners and developers to pressure-test whether a specific office building should become coliving before large sums are committed. That starts with an honest convertibility and market screen, moves through concept design collaboration and a defensible operating model, and continues into operator selection or setup so the finished building actually performs.
With 13 years in coliving, the perspective is that of an operator and consultant, not just an adviser: the underwriting reflects how these buildings really lease up and run, including the staffing, community, and maintenance realities that spreadsheets tend to miss. The goal on every engagement is to kill bad deals early and cheaply, and to give good deals the operating rigor they need to hit their numbers.
Engagements are scoped to where you are, from a fast feasibility read on a single building to full concept-to-operations support across a pipeline.
Worked example
Imagine an eight-story Class B office building in a US downtown with roughly 4,000 square meters of gross area and a floorplate shallow enough that most of the perimeter can hold bedrooms. Office occupancy has drifted down and the owner faces a large capital ask just to compete for shrinking office demand.
A coliving conversion might target roughly 90 to 110 private bedrooms across the upper floors, with shared kitchens and lounges pulled into the deeper core of each floor and a ground-floor amenity and community space. Illustrative numbers only: an acquisition basis reset well below the old office valuation, a conversion budget concentrated in new plumbing risers, window upgrades, and egress, and a stabilized target occupancy in the low nineties.
The point of the scenario is the logic, not the figures: a stranded office asset with the right bones can become a productive residential building when the floorplate cooperates, the acquisition basis is disciplined, and the operating model is built by people who have actually run coliving. Every input here would need real, building-specific underwriting.
