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explanations, outdated and sparse images and graphics, functionality of the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).

commission. City staff will begin the public hearing and adoption process
