City of Tulsa Zoning Code: Districts, Overlays, and Variances

The Tulsa zoning code, Title 42 of the city’s Revised Ordinances, sorts every parcel inside city limits into a district that controls what can be built on it and what activities are allowed there. If your project fits the district’s rules, you can move to a building permit. If it doesn’t, you either change your plan, ask the Board of Adjustment for relief, or apply to rezone the property.

What the Districts Control

Tulsa’s base districts fall into five families: residential, commercial, office, industrial, and mixed-use. Each family runs on an intensity scale, so the code can match rules to a neighborhood instead of applying one standard citywide.

The residential family alone contains fourteen districts. It starts with Residential Single-Family Estate (RE) for large-lot estate homes, runs through six single-family tiers (RS-1 through RS-5), and continues to duplex, townhouse, four multifamily levels (RM-0 through RM-3), and manufactured housing.1Municode Library. Tulsa Code of Ordinances – Chapter 5 Residential Districts As you climb the scale, lots shrink, density rises, and the allowed building types expand from detached houses to apartment complexes.

Commercial districts step up from Neighborhood Commercial (CS) through General Commercial (CG) to High-Intensity Commercial (CH). Office districts (OL, OM, OH) and industrial districts (IL, IM, IH) follow the same pattern, with the heaviest industrial uses limited to IH zones sited away from homes.2Tulsa Planning. Tulsa Zoning Code Mixed-Use (MX) districts allow residential and commercial functions on the same lot or in the same building, but the specific combinations differ by MX sub-district, so check the permitted-use table for yours before you commit.

Within every district, each possible use is labeled permitted by right, allowed by special exception, or prohibited. That table is the first thing to read once you know your district.

Overlays and PUDs

Base zoning is not always the whole story. Tulsa layers overlay districts on top of certain areas to address concerns like historic character, riverfront design, neighborhood infill, and the Route 66 corridor. An overlay supplements the underlying zoning; it doesn’t replace it. If your parcel sits in a Historic Preservation (HP) overlay, for example, exterior changes, new construction, and demolitions require design review by the Tulsa Preservation Commission on top of the normal permit path.3Tulsa Planning Office. Historic Preservation Overlay

Planned Unit Developments are different. A PUD is a negotiated overlay that lets a developer redistribute allowed uses and building intensity across a site, as long as the total density stays within the underlying district’s limits.4Municode Library. Tulsa Code of Ordinances – Chapter 30 Legacy Districts The city no longer accepts new PUD applications, but hundreds of existing PUDs remain in effect and can still be amended. If your property is inside one, the conditions of that PUD’s approval control, sometimes overriding what the base district would otherwise allow.

Looking Up Your Parcel

The Tulsa Planning Office publishes an interactive zoning map on its website.5Tulsa Planning Office. Maps Type in an address and it highlights the parcel and shows the district acronym. Layers let you view overlays, surrounding districts, and pending cases.

The map is a reference tool, not a legal record. Data is compiled from multiple sources and can lag behind recent amendments. Before spending money on a project, confirm the designation through the Planning Office or against the official zoning map referenced in Section 1.100 of the code.

The Rules That Shape a Project

Knowing your district tells you what activities are allowed. The dimensional rules tell you what you can actually build.

Setbacks set the minimum distance between a structure and each property line. Front, side, and rear setbacks vary by district. In single-family districts, front setbacks are usually the most restrictive and are the rule that most often stops a planned addition.

Height limits keep buildings from towering over neighbors. Heights are measured differently depending on roof type and district, so the measurement rules in Chapter 90 are worth reading before assuming your plan complies.

Lot coverage caps the share of a parcel that can sit under buildings and impervious surfaces like driveways and patios. It manages stormwater and prevents over-development on small lots.

Floor area ratio, or FAR, expresses the total floor area of buildings on a lot as a ratio to lot area. A FAR of 0.5 on a 10,000-square-foot lot allows up to 5,000 square feet of floor space, whether in one story or several. FAR is the rule that most often constrains commercial and multifamily projects.

Parking requirements are set by use in Chapter 55. Multifamily buildings, restaurants, and medical offices each have their own ratios. A Parking Impact Overlay or a special exception can sometimes modify them.

Accessory Dwelling Units

Garage apartments and similar secondary residences are allowed in Tulsa, but the path depends on your district. In RE, RS, and agricultural districts, an ADU requires a special exception from the Board of Adjustment. In other districts, an ADU is allowed by right when it is secondary to a household living use.2Tulsa Planning. Tulsa Zoning Code

Only one ADU is allowed per lot. It must sit in a detached accessory building at least 10 feet behind the principal structure, with exterior materials that visually match the main house. Size is capped by the base accessory-building limits for your district plus an additional 500 square feet. In RS-2 through RM districts, the total accessory building area generally cannot exceed 500 square feet (or 40 percent of the principal building’s floor area, whichever is greater) plus the 500-square-foot ADU bonus. Entrances may not face the nearest side or rear property line unless an alley or street runs along that line.

Nonconforming (Grandfathered) Uses

If a property was used legally under older rules but no longer fits the current district, it is a nonconforming use. The code lets it continue, with limits.6Municode Library. Tulsa Code of Ordinances – Chapter 80 Nonconformities

In a residential district, a nonconforming use can only be changed to a use the current zoning actually allows, and once you switch, the nonconforming right is gone for good. In commercial and industrial districts, the Board of Adjustment can approve substituting one nonconforming use for another by special exception, but only if the new use won’t increase negative impacts on the area.

Grandfathered status is lost in three situations:

  • The nonconforming use stops for 36 consecutive months, or 36 months within any four-year window.
  • The building is damaged beyond 50 percent of its replacement cost; re-establishing the use then requires a special exception.
  • The owner voluntarily switches to a conforming use, even briefly.

For nonconforming uses on vacant or unimproved land, the clock is much shorter: 90 days of inactivity ends the status.

Variances, Special Exceptions, and Rezoning

Two bodies handle most zoning decisions, and the right one depends on what you are asking for.

Variances and Special Exceptions

When your project cannot meet a specific development standard, like a setback or height limit, you apply to the Board of Adjustment for a variance. When you want to use property in a way that is conditionally allowed in your district rather than permitted by right, you apply to the same board for a special exception. The BOA is the final decision-maker on both.7Municode Library. Tulsa Code of Ordinances – Section 70.020 Zoning Code Text Amendments If it denies your request, the only appeal is to District Court. The process runs at least 30 to 45 days.8Tulsa Planning Office. Board of Adjustment Application A pre-submittal meeting with a planner is strongly recommended, and the BOA application materials specifically encourage talking with your neighbors before you apply.

Rezoning

Changing the zoning district itself is a map amendment. The Tulsa Metropolitan Area Planning Commission reviews the request against the comprehensive plan and makes a recommendation.7Municode Library. Tulsa Code of Ordinances – Section 70.020 Zoning Code Text Amendments If the proposal departs meaningfully from the plan, a Comprehensive Plan Amendment must run alongside it. The Tulsa City Council has final authority. Start to finish, expect at least 90 days.9Tulsa Planning. City of Tulsa Zoning Code – Application Form

What You File and What It Costs

Every application starts with a legal description of the property from your deed or the Tulsa County Assessor. Rezoning and BOA cases also require a site plan showing lot dimensions, all existing and proposed structures, utility easements, and access to the public right-of-way, plus proof of ownership or written authorization.9Tulsa Planning. City of Tulsa Zoning Code – Application Form Zoning clearance permits, which most building permits require first, can be filed through the City of Tulsa’s self-service portal.10City of Tulsa. Plans Review

The Planning Office mails notice to property owners within 300 feet, publishes a newspaper notice, and posts signs on the property. Neighbors can speak for or against the proposal at the hearing.

Violations and Penalties

Using property in violation of the zoning code is a misdemeanor in Tulsa. The maximum penalty is a $1,200 fine, six months in jail, or both.12Municode Library. Tulsa Code of Ordinances – Chapter 85 Violations, Penalties and Enforcement Every day the violation continues counts as a separate offense, so fines stack up quickly. Liability isn’t limited to the owner: architects, contractors, tenants, and agents who participate in or maintain the violation can each be charged.

Most enforcement starts with a neighbor complaint or an inspector’s observation. For most people the practical cost isn’t jail; it’s the correction work, the daily fines running between notice and fix, and the risk of permit revocation. If a violation notice arrives, dealing with it immediately is the cheapest way out.
