How to Underwrite a Parking Garage

Underwrite a parking garage by tying revenue to the demand drivers around it. Separate transient, monthly and event income, verify collections through the operator's revenue system, and inspect structural condition. Key metrics are revenue per space, monthly versus transient mix, operator fees, structural repair reserves and DSCR on net operating income.

What makes parking garage underwriting different

Parking facilities earn income from transient hourly parkers, monthly contract parkers and events. Demand depends on nearby offices, hospitals, universities, stadiums, airports and retail, and on local transit and parking supply. Revenue can shift quickly when a major demand generator changes, such as an office tenant leaving or a new competing garage opening. Garages are typically run by third-party operators under management agreements or leases. Structured garages require ongoing repairs to concrete, waterproofing, expansion joints and elevators, and deferred maintenance can become costly. Surface lots have lower capital needs but often carry redevelopment value.

Lenders focus on durable demand, operator quality and revenue verification. They prefer garages tied to stable generators such as hospitals or government centers with monthly contracts, and they often apply conservative assumptions to transient and event income. Equity investors underwrite revenue management, technology upgrades such as license plate recognition and online booking, and redevelopment potential. Surface lots in growing urban areas may be valued as land banks. The structure of the operator agreement, whether a management contract or a lease, determines how much operating risk the owner retains.

Key metrics

Revenue per Space

Allows comparison across facilities of different sizes and pricing.

Monthly vs Transient Mix

Monthly contracts provide more stable income than transient parking.

Utilization Rate

Shows how much capacity is used at peak and off-peak times.

Operator Fees

Management fees and incentive fees affect net income to owner.

Structural Repair Reserve

Garages need ongoing concrete and waterproofing repairs.

Owners commonly set annual per-space reserves based on an engineering condition assessment.

DSCR

Confirms NOI supports debt service.

Lenders commonly look for 1.30x or higher given income volatility.

How to underwrite it, step by step

Identify demand generators and analyze their stability.
Obtain revenue reports from parking systems and reconcile to bank deposits.
Separate monthly, transient and event revenue.
Review the operator agreement, fees and obligations.
Commission a structural engineering assessment.
Analyze competing parking supply and pricing.
Size debt on NOI and stress demand declines.
Set structural repair reserves and operator covenants.

Key risks and mitigants

An anchor demand generator such as a major office tenant or hospital relocates or shrinks.

Identify the share of revenue tied to each generator, review their lease or occupancy plans and stress revenue for its loss.

Concrete spalling, waterproofing failure or corroded rebar require major structural repair.

Commission a structural engineering condition assessment and fund upfront and ongoing repair reserves based on it.

Cash or transient revenue is underreported by the operator.

Audit the revenue control system, reconcile ticket counts to deposits and require monthly operator reporting with lender access.

Hybrid work or new transit service reduces daily parking demand.

Separate monthly and transient revenue trends and stress transient and event revenue more heavily than contract revenue.

A new garage or surface lot opens nearby and undercuts rates.

Review planning pipelines and zoning for new parking supply and compare rate positioning with competitors.

Typical financing and deal structure

Parking facilities are financed with bank loans, CMBS, life company loans and private lenders, usually at moderate leverage because transient and event income can swing quickly. Garages anchored by hospitals, universities or government centers with long monthly contracts generally receive better terms. Some owners lease the facility to an operator for fixed rent with percentage rent above a threshold, which converts operating risk into a lease credit analysis. Municipal and airport garages are often financed with revenue bonds. Surface lots held for redevelopment are typically financed like land, with low leverage and recourse. Covenants commonly include structural repair reserves funded from an engineering report, monthly operator revenue reporting, DSCR minimums and lender approval of operator changes.

Red flags

Revenue reports that do not reconcile to deposits.
Heavy dependence on a single office tenant or event venue.
Structural deterioration such as spalling concrete and exposed rebar.
Operator agreement with high fees or unfavorable terms.
Competing garage or transit project nearby.

Frequently asked questions

How do you value a parking garage?

Parking garages are typically valued on net operating income after operator fees and structural reserves, capitalized at a market cap rate. Appraisers also consider revenue per space, demand drivers and redevelopment potential. Surface lots in urban areas may be valued primarily for land. Buyers also check whether the garage serves required parking for an adjacent building under a recorded agreement.

What is the difference between a parking management agreement and a parking lease?

Under a management agreement, the owner keeps revenue and pays the operator a fee, so the owner bears operating risk. Under a lease, the operator pays fixed rent and keeps revenue, taking on operating risk. Underwriting differs significantly based on which structure is used. Lenders generally prefer leases with creditworthy operators.

How do lenders view parking garages?

Lenders view parking garages as operating assets with income tied to local demand. They favor garages with stable demand generators and monthly contracts and apply conservative assumptions to transient and event revenue. Structural condition and revenue verification are key underwriting focus areas. Some also require a lockbox for daily receipts.

What capital costs do parking garages have?

Garages require periodic concrete repair, waterproofing, expansion joint replacement, lighting upgrades, elevator maintenance and revenue control systems. Deferred maintenance can lead to costly structural repairs. Owners rely on engineering assessments to plan and fund these costs. Many owners commission a condition survey every few years to update the repair plan and reserve.
