Thinking about buying or renovating a historic home in Heritage Hills, but not sure what the rules allow? You are not alone. This neighborhood’s beauty is protected by local standards that shape what you can do to exteriors and new work. In this guide, you will learn what needs approval, who reviews your plans, how long it can take, and how to set your project up for success. Let’s dive in.
Why Heritage Hills has extra rules
Heritage Hills sits within Oklahoma City’s Historic Preservation framework, with protections that date to the late 1960s. Parts of the neighborhood are within the Heritage Hills Historic Preservation district, and some blocks also carry a Heritage Hills East overlay. You can confirm boundaries and designations on the City’s official map for Mesta Park, Heritage Hills, and Heritage Hills East.
The neighborhood is also listed on the National Register of Historic Places. That national listing is primarily honorary and can help with certain incentives. The local City designations are what actually regulate exterior changes. For a quick neighborhood history and context, explore the Heritage Hills overview from the neighborhood association.
- Review the City’s historic-preservation overview to understand how the local process works.
- Check the official district map to confirm if a specific property sits in HP or HL areas.
- Read a neighborhood history at Heritage Hills to understand why the district’s character matters.
Who reviews your project
The City of Oklahoma City’s Historic Preservation Commission and Planning Department administer the rules. Most exterior work in Historic Preservation or Historic Landmark overlay areas requires a Certificate of Appropriateness before you start. City planning staff handle administrative reviews for common, guideline-compliant items and prepare larger cases for Commission hearings when needed.
- Learn the City’s process and resources on the Historic Preservation page.
- The Commission applies standards from City code, the City’s Preservation Standards and Guidelines, and the Secretary of the Interior’s Standards.
What work needs approval
If your project affects the exterior, assume it likely needs review. The City’s application packet lists common triggers:
- Roof replacement and significant roof alterations
- Siding replacement or changes in exterior cladding
- Fences, including height and materials
- Yard elements like sheds, decks, and porches
- Additions or new construction
- Window replacement and door changes
Routine interior work and ordinary maintenance usually do not require a Certificate of Appropriateness. That said, work labeled as “maintenance” that changes a character-defining feature could require review. When in doubt, call staff before you begin. The City’s packet details what to submit for each project type and is your primary checklist.
- See the City’s application packet for required documents and project types.
- Review the Zoning and Planning Code for what can be approved administratively and what goes to the Commission.
The review process, step by step
1) Start with staff and local advisors
Talk with Historic Preservation staff early to confirm if your idea needs a Certificate and whether it can be handled administratively. You may also choose to meet with Historical Preservation, Inc. (HPI), the Heritage Hills neighborhood nonprofit. HPI’s Preservation Review Committee offers non-binding design feedback that can help you refine plans before filing.
- Contact details for City staff are listed in the application packet.
- Learn about HPI and its Preservation Review Committee.
2) Prepare a complete submittal
The City expects a clear scope of work, current photos keyed to the specific changes, drawings or elevations, site plans when relevant, and material specifications or product cut sheets. Window projects require especially thorough documentation that shows existing conditions and proposed details. The cleaner your package, the faster the review.
- Follow the documentation checklist in the application packet.
- For windows, reference the City’s Historic Window Overview for expectations.
3) File and pay fees
The City screens your application for completeness, then assigns it to administrative review or schedules a Commission hearing. Typical fees listed in the packet are: 100 dollars for administrative review, 200 dollars for a Commission case without new construction, and 300 dollars for Commission review that includes new construction. Staff may request additional information shortly after submittal.
- Fee details and submittal steps are in the application packet.
4) Understand hearings, notice, and appeals
If your case requires a hearing, the City provides public notice by mail and publication under the Zoning and Planning Code. You should attend the hearing so you can answer questions and respond to design feedback. Decisions can be appealed to the Board of Adjustment. Plan for the standard appeal window after a decision before starting work.
- See the Zoning and Planning Code for notice and appeal procedures.
5) Track timing, approvals, and expirations
Once issued, Certificates of Appropriateness typically expire one year from the approval date. The Historic Preservation Officer may grant a one-time extension of up to six months. The Commission may allow an additional extension within code limits. Starting work before you receive a Certificate can trigger a violation and require a post-facto review, which can add time and cost.
- Expiration and extension rules are outlined in the Zoning and Planning Code.
What design standards mean for you
City reviewers look for compatibility with the district. They consider materials, scale and height, setbacks, window proportions, roof forms, and rhythm along the street. Contemporary design can be approved when it is compatible and does not create a false sense of history. The Secretary of the Interior’s Standards guide the goal of preserving character while allowing for sensitive upgrades.
- Read the City’s Zoning and Planning Code section for preservation standards.
Windows and character features
The City and national guidance strongly encourage you to repair historic windows rather than replace them outright. If you believe replacement is necessary, you will need to document the reasons and submit measured details and manufacturer specifications. Storm windows and targeted weatherization can improve comfort while protecting original sash and glass.
- Use the City’s Historic Window Overview for repair-first strategies and documentation.
- See the National Park Service’s guidance on weatherizing historic buildings.
Additions, infill, and demolition basics
Additions and new buildings should be compatible in massing, materials, setbacks, and orientation, and they should not overwhelm the original house. Reviewers also look for a clear distinction so that new work does not read as faux historic. Designs that are compatible and honestly new tend to meet the standards.
Demolition requests receive high scrutiny. The Commission approves demolition only in limited cases such as a confirmed public-safety threat, a noncontributing structure, or a finding of no viable economic use. Economic hardship cases go to an Economic Review Board and require extra documentation and time. If you are considering a teardown or partial demolition, plan early and expect a rigorous evidentiary process.
- Compatibility and demolition standards are in the Zoning and Planning Code.
Incentives and expert resources
If your property is income producing, you may be eligible for the 20 percent Federal Historic Rehabilitation Tax Credit. Owner-occupied single-family homes usually do not qualify for this federal program. The Oklahoma State Historic Preservation Office can advise on current state programs and the federal process.
Technical help is available too. The National Park Service publishes practical briefs on repairing and weatherizing historic buildings, and the City’s window guide offers everyday solutions for Heritage Hills homes.
- Explore OK SHPO guidance on tax credits and incentives.
- See NPS technical resources on weatherization and windows.
- Review the City’s Historic Window Overview for local guidance.
Quick buyer and owner checklist
- Confirm the property’s overlay and boundary status using the City’s HP district map.
- Ask City staff whether the house is listed as contributing or noncontributing in the district inventory.
- Discuss your concept with Historic Preservation staff early, and consider feedback from HPI’s Preservation Review Committee.
- Budget for documentation and fees. The application packet lists required photos, drawings, and specs, plus current fees. Allow time for staff scheduling, Commission dates if needed, and the appeal period after approval.
- Prioritize repair over replacement, especially for windows and original features. Use the City’s window guide and NPS briefs for energy upgrades that retain character.
- If you are planning a major addition or demolition, expect a longer review with added technical and economic documentation under the Zoning and Planning Code.

Common project scenarios
Replacing a worn roof
Most roof replacements need review. If you plan a like-for-like replacement that meets the standards, staff may approve it administratively. Changing roof form or materials could push the project to the Commission, so align your specs with the guidelines.
Adding a rear deck or porch
Decks and porches are listed triggers in the application packet. A sensitively scaled rear deck with materials compatible with the house may qualify for administrative approval. Visible front or side porches with design changes often require Commission review.
Upgrading windows for energy performance
Start by evaluating repair. Original sash with weatherstripping, interior or exterior storms, and careful glazing repairs can cut drafts while retaining character. If replacement is necessary, be ready with measurements, sections, and manufacturer details that match historic profiles, and follow the City’s window guidance.
Building an addition
Begin with massing and scale. Keep the addition subordinate to the main structure, match setbacks and roof forms, and differentiate new from old in a respectful way. Early staff input and optional HPI feedback can help you avoid redesigns before a Commission hearing.
Partner with a local expert
