RFP 26-911 | Updates to Design Guidelines for Historic Preservation Districts in Tulsa | Issue Date: 2/2/26
I.
OVERVIEW AND GOALS:
With this Request for Proposal (RFP), the City is soliciting proposals to secure
professional services to update the Tulsa Preservation Commission’s Unified
Design Guidelines for residential and non-residential structures within Tulsa’s
historic preservation (HP) overlay zoning districts. The goal of the project is to
update and add necessary details to the design guidelines to clearly describe
appropriate treatments of properties within HP overlay districts. The Unified
Design Guidelines are a guiding document the preservation commission uses in
its review of applications for HP permits. In addition, the design guidelines are a
resource for historic property owners in maintaining or altering their properties.
The project is funded by a federal matching grant-in-aid from the U.S.
Department of the Interior’s Historic Preservation Fund, administered by the
Oklahoma State Historic Preservation Office (OK/SHPO).
We enthusiastically look forward to receiving Your proposal.
II. BACKGROUND:
Tulsa has eight (8) HP overlay zoning districts, in which an HP permit is required
for most exterior changes made to a property. This includes rehabilitation as well
as other types of projects, such as additions, new construction, demolition, and
some landscape features. In its review of applications for HP permits, the Tulsa
Preservation Commission must use adopted design guidelines to evaluate the
proposed work.
Prior to the adoption of Unified Design Guidelines, each HP overlay district in
Tulsa was governed by its own set of guidelines. The distinct neighborhood
guidelines were consolidated into one set of Unified Design Guidelines in 2012,
with subsequent amendments adopted in 2017 and 2024. The site of the Council
Oak Tree and Stickball Park maintains its own set of design guidelines. The
current Unified Design Guidelines may be found at
https://tulsapreservationcommission.org/hp-permit/guidelines/.
The Tulsa Preservation Commission would like to update the existing Unified
Design Guidelines. Identified concerns include lack of definitions and
explanations, outdated and sparse images and graphics, functionality of the
document, consistency with the Tulsa Zoning Code, and loss of details about
architectural features unique to each district that occurred when previous
guidelines were replaced.

IV. SCOPE OF WORK:
The selected Respondent shall provide the following services:
1. Using the existing design guidelines as a foundation, the selected
Respondent shall update the residential and non-residential Unified Design
Guidelines. The updated design guidelines should include details, such as
diagrams, images, examples, and direct language, that are necessary to
clearly describe appropriate treatments of properties within HP overlay
districts. The updated design guidelines should reflect best practices in
preservation, including the Secretary of the Interior’s Standards and
Guidelines for the Treatment of Historic Properties. The updated design
guidelines should also reflect the periods of significance, architectural styles,
and character-defining features within the applicable HP overlay districts in
Tulsa. The design guidelines may be restructured but must cover the same
types of projects (rehabilitation, additions, new construction, demolition,
landscape features, etc.). The updated design guidelines must also be
consistent with the HP permit requirements found in Section 70.070 of the
Tulsa Zoning Code (https://tulsaplanning.org/plans/TulsaZoningCode.pdf).
