| Compensation Actually Paid vs. Total Shareholder Return [Text Block] | Compensation Actually Paid and Total Shareholder Return TSR is a component of executive performance evaluated by the Compensation Committee and therefore TSR and TSR relative to the peer group have a direct impact on executive compensation. In 2022, the Company’s TSR was lower than the Peer Group TSR. Compensation Actually Paid for the PEO and non-PEO NEOs was materially lower in 2022 than in the prior year. In 2021 the Company’s TSR on an absolute basis and as compared to the peer group was exceptional, which contributed to higher executive compensation. In 2020, the Company’s TSR was negative and slightly below the peer group, which had a negative impact on executive compensation, noting, however that the COVID-19 pandemic broadly disrupted markets in 2020. | ||
| Compensation Actually Paid vs. Net Income [Text Block] | Compensation Actually Paid and Net Income Net Income is not a measure directly considered by the Compensation Committee and therefore has an indirect impact on executive compensation. Net Income can be impacted by non-cash items and significant one-time events, such as gains or losses on sale, which can cause Net Income to be a non-indicative measure of overall performance in certain years. In 2022, the Company’s Net Income was positive. In 2021, Net Income was substantial due to a gain on sale associated with the sale of the Company’s life science portfolio. In 2020, the Company’s Net Income was positive. | ||
| Compensation Actually Paid vs. Company Selected Measure [Text Block] | Compensation Actually Paid and Revenue Percent Change Revenue Percent Change indicates the increase or decrease in rental and other revenues as compared to the prior year. This measure can indicate a growth in the Company’s portfolio or an increase in the amount of revenues derived from the Company’s properties. In 2022, the 10.0% Revenue Percent Change was primarily driven by the successful purchase, integration and stabilization of three properties that were acquired in December 2021. In 2021 and 2020, the 2.0% and 2.9% Revenue Percent Change are indicative of a growth in revenues, strong rent collection and a relatively stable asset base. These positive factors were considered by the Compensation Committee in determining executive compensation. | ||
| Tabular List [Table Text Block] | Financial Performance Measures As described in more detail in the Compensation Discussion and Analysis section, our executive compensation program reflects a philosophy of aligning the Company’s interests with those of our management. The metrics that we use for our long-term incentive awards are selected based on an objective of incentivizing our NEOs to increase the value of our enterprise for our shareholders. The most important financial performance measures we use to link executive compensation actually paid to our NEOs, for the most recently completed fiscal year, to our performance are as follows: • Achievement of Leasing Targets • Core FFO per Share • Total Shareholder Return • Achievement of Occupancy and Rent Collection Targets • Leverage and Liquidity Metrics • Achievement of Acquisition and Disposition Targets | ||
