Recent sales of similar properties, used to estimate what a lot or parking space is worth in the current market. See the Parking Space Value Calculator.
D
Daily maximum (daily max)

Frequently Asked Questions
What does transient parking mean?
Transient parking is short-term, pay-as-you-go parking by drivers who do not have a monthly contract. It is usually billed by the hour or by the day.
What is the difference between pay-and-display and pay-by-plate?
With pay-and-display, the driver pays at a machine and places the receipt on the dashboard. With pay-by-plate, the driver enters the license plate number when paying, so no receipt needs to be displayed.
What is net operating income (NOI) for a parking lot?
Net operating income is gross parking revenue minus operating expenses, before loan payments and income taxes. It is the income figure used to calculate a lot's cap rate.
What is the difference between a gross lease and a triple net lease?
In a gross lease, the landlord typically covers property expenses such as taxes and insurance. In a triple net (NNN) lease, the tenant typically pays those expenses and maintenance on top of rent. Terms vary by contract, so read each lease carefully.
What does parking validation mean?
Validation is when a business or venue covers or discounts a customer's parking cost, often through a stamped ticket or a code entered at exit.
