Value-Add Opp | Office & Parking Lot Dev 2 Office Properties Online Auction Sale Denver, CO

Capitol Center offers an opportunity to acquire a landmark two-building office complex in the heart of Denver's Capitol Hill submarket, steps from the Colorado State Capitol and Civic Center Park. The complex totals 156,928 sf and comprises the Capitol Life Tower, a 12-story, 134,071-square-foot office building with fully renovated common areas, a 12th-floor rooftop terrace, and move-in-ready spec suites, and the Colorado Trust Building, a 22,857-square-foot, two-story Classical Revival landmark with exceptional historic character and a grand two-story entrance hall. The property sits on a full city block at 225 E. 16th Avenue, with an attached two-level parking structure that currently generates over $350,000 in annual net revenue.

Capitol Center will be acquired at a significant discount due to the previous ownership's total invested basis of over $33M, offering high-quality space, historic character, and a fully amenitized building that cannot be replicated anywhere near the likely acquisition price in today's environment. The combination of a successful real estate tax appeal and in-place parking income positions the asset at or near break-even NOI today, before a single incremental lease is signed.

The Colorado Trust Building offers a turnkey headquarters at a below-replacement-cost basis, with the Tower available for third-party lease-up to offset carrying costs. The tower's renovated common areas, fitness center, and spec suites provide a turnkey product in a submarket anchored by government, legal, and professional services demand, with parking revenue providing a durable income floor throughout the lease-up period. Both buildings' National Register of Historic Places status unlocks meaningful federal and state historic tax credit eligibility, the site's C-MX-12 zoning supports up to 12 stories of additional density, and the Denver Downtown Development Authority has committed over $90M specifically toward office-to-residential conversions in the urban core, with Capitol Center positioned as a priority asset within that program.

Capitol Center is a fully amenitized, institutionally managed office complex offered at a price point that is simply not replicable through new construction, with a combination of income characteristics, physical attributes, and entitlement optionality that distinguishes it sharply from the distressed office sales that have defined this market in recent years. Capitol Center arrives with an existing income stream that substantially offsets ownership costs, multiple well-defined paths to value creation, and a location steps from the Colorado State Capitol that has sustained professional and government demand for decades.

The property's attached two-level parking structure currently generates over $350,000 in annual net revenue: income that persists regardless of office occupancy and that, combined with the reduction in real estate taxes resulting from a successful tax appeal, positions the asset at or near break-even NOI at today's below-market occupancy levels. It is a stabilized income asset with significant embedded upside, offered at a basis that reflects the current environment rather than the asset's long-term potential.

The Colorado Trust Building: a 22,857 sf, Classical Revival landmark constructed in 1924 by Denver architect Harry James Manning. Faced in yule marble with terra cotta trim, the building is listed on both the Colorado State Register of Historic Places and the National Register of Historic Places, and its grand two-story entrance hall, private office configuration, and intimate scale make it ideally suited for a law firm, foundation, association, or professional services organization seeking a presence in the Capitol Hill corridor. For larger users, the Capitol Life Tower provides flexible multi-floor opportunities across approximately 11,000 sf floor plates, with move-in ready spec suites, recently renovated common areas, a fitness center, and a fully amenitized 12th floor rooftop terrace with views of the State Capitol and the Central Business District: all in place and requiring no additional capital investment.

The Capitol Life Tower's current 18% occupancy represents a lease-up opportunity in a building that has absorbed significant capital on the improvements that matter most. Over $4.5M in recent renovations, including lobby improvements, corridor and restroom upgrades, a fitness center, bicycle storage, and move-in-ready spec suites, gives a new owner a meaningful head start on the lease-up process while still leaving room to tailor future suite buildouts to specific tenant requirements.

The surrounding tenant base of government agencies, legal firms, and professional services represents the same demand profile that has historically supported this submarket, and the parking revenue provides a durable income floor while that lease-up occurs.

Both buildings are listed on the National Register of Historic Places, making them eligible for the Federal Historic Rehabilitation Tax Credit (20% of qualified rehabilitation expenditures) as well as the Colorado Commercial Historic Preservation Tax Credit (25% of the first $2M in eligible costs, plus 20% of costs above that threshold). For a buyer pursuing residential conversion, Colorado has established a dedicated housing pool offering up to $1.5M in credits annually for projects converting a minimum of 50% of the building's square footage to net new rental housing units, with an additional 5% credit rate available for projects subject to an affordable housing deed restriction.

Capitol Center sits at the forefront of the Denver Downtown Development Authority's urban revitalization priorities. The DDDA has expanded its boundary to cover the entirety of Downtown Denver and has access to $570M in total investment capacity, with office-to-residential conversions on and near 16th Street representing a stated funding priority: to date, the DDDA has committed over $90M specifically toward financing office-to-residential conversions in the urban core.

A 2025 adaptive reuse case study conducted by ICF concluded that Capitol Center presents lower barriers to residential conversion, citing specifically the existing scissor stair configuration that satisfies Denver Building Code egress requirements, the 12th-floor amenity space can serve future residents with no changes, and a concrete structure confirmed sufficient for residential occupancy loads. A Concept Plan submitted to the City in June 2022 outlines a program for 122 residential units within the Capitol Life Tower and an additional 243-unit new residential tower on the parking parcel: a total of 365 units that would represent one of the most significant urban infill projects in the Capitol Hill submarket. Historic tax credit eligibility applies to the conversion program as well, and the existing 4’ water tap on the property represents cost savings of approximately $670,000.
