570.102 Definitions.

“ANSI/BOMA Office Area (ABOA)” means the area “where a tenant normally houses personnel, and/or furniture, for which a measurement is to be computed,” as stated by the American National Standards Institute/Building Owners and Managers Association(ANSI/BOMA)publication Z65.1-1996.

“Contract” means lease.

“Contractor” means lessor.

“Landlord” or “lessor” means any individual, firm, partnership, trust, association, State or local government, or other legal entity that leases real property to the Government.

The lease agreement may not bind the Government for more than 20 years.

(b)  The contracting officer has exclusive authority to enter into and administer leases on the Government’s behalf to the extent provided in the certificate of appointment as a contracting officer. Nothing in this paragraph is intended to limit the contracting officer’s authority to designate, consistent with statute and regulation, a contracting officer’s representative.

570.104 Competition.

570.105 Methods of contracting.

570.105-1 Contracting by negotiation.

Contracting by negotiation is appropriate for acquiring space in a building through a lease contract. The contracting officer will usually need to conduct discussions with offerors about their proposals and consider factors other than price in making the award.

570.105-2 Criteria for the use of two-phase design-build.

The contracting officer may use the two-phase design-build selection procedures in 41 U.S.C. 253m for lease construction projects. This includes lease construction projects with options to purchase the real property leased. Use the procedures in 41 U.S.C. 253m and FAR 36.3 when the conditions in (a) and (b) below are met:

(a)  The contracting officer anticipates that the lease will involve the design and construction of a building, facility, or work for lease to the Government.

(b)  The contracting officer determines whether the procedures are appropriate for entering into a lease construction contract based on the following:

(1)  The contracting officer expects to receive three or more offers.

(2)  Offerors will need to perform design work before developing a price.

(3)  Offerors will incur a substantial amount of expense in preparing offers.

(4)  The contracting officer considers criteria such as the following:

(i)  The extent to which the project requirements have been adequately defined.

(ii)  The time constraints for delivery of the project.

(iii)  The capability and experience of potential contractors.

(iv)  The past performance of potential contractors.

(v)  The suitability of the project for use of the two-phase selection procedures.

(vi)  The capability of the agency to manage the two-phase selection process.

(vii)  Other criteria established by the HCA.

(c) See 570.305 for additional information.

570.106 Advertising, publicizing, and notifications to Congress.

(a) If a proposed acquisition is not exempt under FAR 5.202 or GSAR 570.106(e), and is for a leasehold interest in real property estimated to exceed 10,000 square feet, then the contracting officer must publicize the proposed acquisition in the System for Award Management Contract Opportunities at in its place.

(b) For leasehold acquisitions where the solicitation requires the construction of a new building on a preselected site, the contracting officer, in accordance with the timeframes established in FAR 5.203, must publicize the proposed acquisition in the GPE regardless of size or value.

(c)  For leasehold acquisitions not subject to a square foot measurement (e.g., antennas, piers, parking), contracting officers must publicize the proposed acquisition in the GPE when the contract action is expected to exceed $25,000, unless an exception under FAR 5.202 applies.

(d)  Other than as identified in paragraphs (a) through (c) of this section, the contracting officer need not publicize the proposed acquisition of a leasehold interest in real property, including expansion requests within the scope of a lease (see 570.403), lease extensions under the conditions defined in 570.405, and building alterations within the scope of a lease (see 570.5). However, the contracting officer may publicize proposed lease acquisitions of any dollar value or square footage in the GPE or local newspapers if, in the opinion of the contracting officer, doing so is necessary to promote competition.

(e)  The contracting officer may issue a consolidated advertisement for multiple leasing actions.

(f)  Except as otherwise provided in paragraph (b) of this section, where publicizing of the proposed acquisition is required, the notice shall be published in the GPE not less than three calendar days prior to issuance of a solicitation.

(g)  Except as otherwise provided in paragraph (b) of this section and as set forth in paragraphs (g) and (h) of this section, the contracting officer shall provide offerors not less than 20 calendar days between solicitation issuance and the date established for receipt of initial offers.

(1)  For a proposed acquisition using simplified lease acquisition procedures (see 570.2), consider the individual acquisition and establish a reasonable response time.

(2) In cases of unusual and compelling urgency (FAR 6.303-2), provide as much time as reasonably possible under the circumstances and document the contract file.

(h)  If a Member of Congress has specifically requested notification of award, the contracting officer must provide award notifications in accordance with 505.303.

570.106-1 Synopsis of lease awards.

(a)  Except for lease actions described in paragraph (b) of this subsection, contracting officers must synopsize in the GPE awards exceeding $25,000 total contract value that are likely to result in the award of any subcontracts. However, the dollar threshold is not a prohibition against publicizing an award of a smaller amount when publicizing would be advantageous to industry or to the Government.

(b)  A notice is not required if—

(1)  The notice would disclose the occupant agency’s needs and the disclosure of such needs would compromise the national security; or

(2)  The lease—

(i)  Is for an amount not greater than the simplified lease acquisition threshold;

(ii)  Was made through a means where access to the notice of proposed lease action was provided through the GPE; and

(iii)  Permitted the public to respond to the solicitation electronically.

(3)  Justifications for other than full and open competition must be posted in the GPE. Information exempt from public disclosure must be redacted.

570.107 Oral presentations.

The contracting officer may require oral presentations for acquisitions of leasehold interests in real property. Follow the procedures in FAR 15.102.

570.108 Responsibility determination.

(a) Determine that the prospective awardee is responsible with respect to the lease under consideration. The standards in FAR 9.104 apply. As part of the determination that a prospective contractor is otherwise qualified and eligible for award, review exclusions in the System for Award Management (SAM).

(b)  The contracting officer’s signature on the contract is deemed an affirmative determination.

(c)  If the contracting officer finds an offeror nonresponsible, sign and place in the contract file a determination of nonresponsibility. State the basis for the determination.

(d) If the contracting officer finds a small business concern nonresponsible, the procedures at FAR 19.6 apply. Place all documents and reports supporting a determination of responsibility or nonresponsibility in the lease file.

570.109 Certifications.

Before awarding a lease, review applicable representations and certifications for compliance with statute and regulations.

570.110 Cost or pricing data and information other than cost or pricing data.

(a) The policies and procedures of FAR 15.403 apply to lease contract actions.

(b) FAR 15.403-1 defines exceptions to and waivers for submitting cost or pricing data. Most leasing actions will have adequate price competition. For price analysis of offered rental rates, the contracting officer may use a market survey, an appraisal conducted using accepted real property appraisal procedures to establish a market price for comparison, or other relevant market research data. For price analysis of offered tenant improvement costs, obtain two offers or cost and pricing data.

(c) In exceptional cases, the requirement for submission of certified cost or pricing data may be waived under FAR15.403-1(c)(4).

(d) If cost or pricing data are required, follow the procedures in FAR15.403-4 and 15.406-2.

570.111 Inspection and acceptance.

Before accepting the space, the contracting officer must verify that the space complies with the Government’s requirements and specifications and document this in an inspection report. The inspection and acceptance document must contain the square footage accepted and the acceptance date. Include the inspection and acceptance in the contract file. When space such as piers, antennas, and parking are leased, square footage may not be the manner in which the amount of space is specified; therefore, document that the space complies with the Government’s written requirements.

570.112 Awards to Federal employees.

If the contracting officer receives an offer from an officer or employee of the Government, follow the procedures in FAR 3.6.

570.113 Disclosure of mistakes after award.

If a mistake in a lessor’s offer is discovered after award, the contracting officer should process it substantially in accordance with FAR 14.407-4 and GSAM 514.407-4.

570.114 Protests.

FAR 33.1 and 533.1 apply to protests of lease acquisitions.

570.115 Novation and change of ownership.

In the event of a transfer of ownership of the leased premises or a change in the lessor’s legal name, FAR 42.12 applies.

570.116 Contract format.

The uniform contract format is not required for leases of real property.

570.117 Sustainable requirements for lease acquisition.

Contracting officers must include sustainable design requirements appropriate for the type of leasing action in the solicitations for offers. Contracting officers can find solicitation requirements and instructions on under Leasing Policies and Procedures, Green Leasing, and in the Leasing Desk Guide to assist them in complying with GSA’s sustainable requirements identified in this part.

(a)  Pre-Award Procedures. The contracting officer must ensure that the sustainable requirements within the lease templates are included in the awarded lease as specified by the PBS Leasing Desk Guide. Review Chapter 18 of the PBS Leasing Desk Guide that can be found on GSA's Acquisition Portal at for guidance on ensuring sustainable requirements are included in leases.

(b)  Post-Award, Pre-Occupancy Procedures.

(1)  Sustainability Procedures. For specific post-award sustainability procedures, review Chapter 18 of the PBS Leasing Desk Guide.  

(2)  Receipt of Sustainable Products and Services.

(i)  The contracting officer must take reasonable steps to validate any required sustainable products and/or services are received. Review the best available evidence of compliance such as manufacturer product documentation, design submittals, or green lease submittals to ensure the lessor is providing required sustainable products and services.

(ii)  The contracting officer must note any discrepancies with sustainable requirements in the lease and provide feedback to the lessor.

(iii)  When choosing what documents to review during sustainability compliance reviews, random sampling techniques can be utilized to limit the number of documents/evidence being reviewed. Staff/Service Offices may prioritize which products and/or services to focus on in their compliance reviews. For specific best practices in verifying evidence of compliance, review the Verification Guide for Purchasers of Sustainable Products at

(c)  Post-Occupancy Procedures. The contracting officer must take reasonable steps to validate the lessor complies with all post-occupancy sustainable requirements in the lease. Review the Lease Management Desk Guide that can be found on GSA's Acquisition Portal at for guidance on monitoring and documenting lessor compliance with all post-occupancy sustainable requirements.

(d)  Sustainability Exceptions. If at any point during a real property lease acquisition the contracting officer determines that one of the mandatory sustainable requirements should not be included in the lease due to an allowable exception, the contracting officer must follow any applicable procedures as stated within the PBS Leasing Desk Guide.

(e)  Compliance Monitoring and Reporting.

(1)  Review Process. The PBS Leasing Office is responsible for lease compliance monitoring to determine compliance with the sustainable acquisition criteria specified in 570.117(e)(2). The PBS Leasing Office is responsible for coordinating these reviews with the GSA Office of Acquisition Policy. PBS Leasing Office is required to submit the results of these reviews to the GSA Office of Acquisition Policy. GSA Office of Acquisition Policy is required to monitor and report sustainable acquisition activity to the GSA Chief Sustainability Officer in support of the agency’s semiannual status report to Office of Management and Budget.

(2)  Determining Compliance. See the GSA Sustainable Acquisition Review Criteria document that can be found on GSA's Acquisition Portal at for the specific criteria used to determine compliance with sustainable acquisition requirements.

570.117-1 Federal leadership in environmental, energy, and economic performance.

In order to create a clean energy economy that will increase our Nation’s prosperity, promote energy security, protect the interests of taxpayers, and safeguard the health of our environment, GSA will accomplish all requirements of E.O. 13514 that apply to lease acquisition.
