Concrete in a Tulsa historic district: when the HP Permit applies

A homeowner in Gillette, Swan Lake, Yorktown or North Maple Ridge can pour a patio behind the house without asking anyone. The same owner who widens a driveway or replaces the walk to the porch walks into a different set of rules. This note follows the City's zoning code, the Tulsa Preservation Commission's pages and the residential design guidelines through the questions that come up before a street-facing concrete job, retrieved November 8, 2026.

Which neighborhoods are covered

The Preservation Commission's list of HP zoned neighborhoods names eight: Brady Heights (zoned December 20, 1999), the Council Oak Tree site (January 31, 1992), Gillette (March 24, 1989), North Maple Ridge (April 12, 1993), Swan Lake (February 14, 1994), Yorktown (August 14, 1995), Elmwood, the Patrick J. Hurley Mansion (October 22, 2015) and Tracy Park (November 30, 2022), retrieved November 8, 2026. The page calls the HP Permit process mandatory and says owners must receive a permit before changing or repairing the exterior of a property, even if no building permit is needed.

A National Register listing is a different thing. The Commission's zoning explainer describes local HP zoning as local protection and National Register listing as nationwide recognition, notes that the two often overlap, and says listing alone does not require a neighborhood to adopt HP zoning. For a house on the edge of one of these areas, the page sends owners to the Tulsa Planning Office for official verification, and the Planning Office's property information page points to the zoning code and the zoning maps. The Commission's guidelines page also posts a district map for Brady Heights, Elmwood, Gillette, North Maple Ridge, Swan Lake, Tracy Park and Yorktown.

What the zoning code says triggers a permit

The rule is in section 70.070-A of the Tulsa Zoning Code, the edition dated October 26, 2026. Within an HP zoning district, an HP permit must be obtained before any work is performed on or changes are made to an existing building, structure or lot, unless the work is exempt. The examples it gives include construction, reconstruction, alteration, removal and demolition, whether or not a building permit is required, retrieved November 8, 2026.

Concrete is inside that language twice. The code's definition of a structure covers buildings, parking areas, walks, fences, canopies and signs, so a walk is a structure. The word lot covers the ground itself. The Commission's own summary is plainer: any exterior alterations or repair, new construction or demolition within a historic preservation zoned neighborhood must be approved first by the Commission or its staff.

What is exempt

Section 70.070-B lists work that needs no HP permit. Four of its lines matter for flatwork. Ordinary maintenance and repair is exempt. Portions of buildings, structures or sites that are not visible from adjoining streets are exempt. Accessory structures such as sheds, garages, decks, patios, fencing and pools are exempt, provided they are not located in street yards. General landscape maintenance and planting are exempt too.

The street yard is defined in the code's glossary as the yard along the full width of the lot from the street lot line to the facade of the principal building oriented toward the street, not counting porches, chimneys and bay windows. In plain terms, it is the strip of lawn between the sidewalk and the front wall of the house. A patio behind the house falls outside it. A walk or drive across it does not, and the residential design guidelines say landscape features are reviewed only in the street yard, while fences, walls and paving in the side or rear yard are exempt from review.

The code does not define ordinary maintenance and repair in the pages read for this note, so a job that sits near that line is a question for Commission staff before it is a question for a contractor. Section 70.070-K helps with a narrower case: the preservation officer may approve work on existing structures that replaces existing materials with equivalent materials, if the work complies with the design guidelines. The Commission's page says staff can issue some permits without a full Commission review, and it invites owners to ask which exemptions apply.

The paving rules in the guidelines

The Commission's Unified Design Guidelines for residential structures carry the standards. The guidelines page says the council approved the revisions on January 11, 2017, effective February 22, 2017, and a later revision to the non-residential guidelines took effect on February 6, 2024. Section G.2 covers paving. It asks owners to retain and preserve original historic paving, steps and bulkheads through repair, to make new paving consistent with the historic elements found along the same street and in the same neighborhood, and to use paving materials consistent with the historic paving on that street. It says asphalt and stained concrete are not allowed.

Two caption notes in the same section help a buyer of concrete. One describes bulkheads as the sloped strips of paving flanking steps, flush with the sidewalk and not raised above it. The other says driveways in Tulsa were historically plain concrete slabs and calls the ribbon driveway a great alternative, because it uses less concrete, creates less runoff and is historically appropriate.

The site rules sit in section B.2, with matching lines in the other sections. Limit paving within the street yard to primary driveways and sidewalks. Curb cuts and new driveways through the street yard are strongly discouraged for properties with alley access. On interior lots, driveways and sidewalks together may cover no more than 50 percent of the street yard, with Elmwood held to 25 percent, and on corner lots no more than 30 percent.

The guidelines do not address integral color or stamped patterns in the paving lines read for this note, only stained concrete, so a decorative surface is a question for staff. The decorative concrete note covers the weather side of those finishes.

Where the question turns into a job

If the house stands inside one of these districts and the old drive needs replacing, the concrete driveways page is where a bid starts, but the HP Permit has to come first or alongside it. The approach, the sidewalk crossing and the City's right-of-way permit are covered in the driveway permit note, and they are separate from the Commission's review. For a front path, steps or the public walk, the sidewalks and walkways page sorts a private walk from the City's.

Only the owner or the owner's authorized agent may file. Section 70.070-C says applications for an HP permit may be filed only by the property owner or the owner's authorized agent, so ask any bidder who offers to handle the paperwork to say in writing that they will act as that agent, and what they will charge for it.

How the permit process runs

The application page says the form is two pages, is used for all projects, and carries no fee. Supporting documents named there are color photographs of each affected side of the property, a site plan no larger than 11 by 17 inches showing structures, property lines and neighboring structures, elevation sketches or drawings with materials noted, product brochures or material samples, photographs or reports of damage if the work is a repair, and photographs of similar work already in the neighborhood, preferably on the same street. The page asks applicants to answer what exists now, what is proposed, whether it meets the district guidelines and how it relates to other properties on the street.

The process page asks owners to submit the application and documents to Commission staff by email or in person, and not through the City's Self Service Portal. A typical application is presented at two meetings, first to the HP Subcommittee and then to the full Commission, which votes to approve or deny. An approved permit is typically issued within a few business days. The page names the Commission's staff as the first contact, and the draft guidelines page lists planning@cityoftulsa.org and 918-596-7526.

The zoning code puts a clock on the Commission. Section 70.070-E says it must meet within 30 business days of a complete application and approve, approve with conditions or deny, and that failing to act within that time counts as approval unless the applicant agrees to an extension or does not attend the meeting. The criteria in section 70.070-F are the guidelines plus how far the work alters the historic resource and whether it fits the district's character.

After approval, the clock moves to the owner. Under section 70.070-H, an approved permit lapses two years after approval unless a building permit has been issued and the work is under way, or, where no building permit is required, the work is finished within the two years. The Commission may extend by up to one year. A permit runs with the land, so it survives a sale, and a change to the approved plan has to go through as a new application.

A denial can be appealed. The process page says any final decision may be appealed to the board of adjustment under section 70.140, and that appeal applications must be filed with the City Clerk and the Clerk of the Board of Adjustment within 10 days of the decision. For an application, a fee schedule or questions about appeal, it gives planning@cityoftulsa.org.

The guidelines are being rewritten

The Commission has partnered with RDG Planning and Design to update the Unified Design Guidelines. Its update page invites comment on the draft through November 25, 2026, says the Commission will consider revisions in December 2026 or January 2027, and adds that the planning commission and the city council follow. The announced changes include more guidance on what types of projects need an HP permit, a chapter on masonry and one on new or replacement materials. Nothing in the draft has been adopted, so ask staff which text applies when you file.

Before you ask for bids

1. Confirm the district. Check the zoning map and the district maps, and ask the Planning Office to verify the lot if the address is near an edge.
2. Sort the work. Street yard or not, visible from the street or not, like-for-like replacement or something new.
3. Photograph what exists. The existing drive, walk, steps and any bulkheads, and the same features on neighboring lots.
4. Ask for a plain, uncolored finish. Stained concrete is not allowed, and other treatments are a staff question.
5. Call staff early. The Commission's pages ask owners to consult staff before applying.
6. Add the locate call. Digging for the new base needs a ticket too, as the Okie811 note explains.

The Maple Ridge notes and the notes on Gillette, Swan Lake and Yorktown carry the local detail. The quote form sends the address, the measurements and the district to an independent local contractor, who calls back to confirm the scope and the price.
