Are you getting a historic San Antonio home ready to sell? The last thing you want is a permit surprise slowing a buyer’s loan or causing last‑minute negotiations. You can avoid stress by confirming what work needed approval, gathering paperwork early, and answering buyer questions with confidence. This guide shows you what typically needs a Certificate of Appropriateness, how to document approvals, and how to manage timing so your deal stays on track. Let’s dive in.
Who reviews historic changes in San Antonio
If your home is a designated landmark or lies within a local historic district, exterior changes are reviewed by the City of San Antonio Office of Historic Preservation (OHP). The Historic and Design Review Commission (HDRC) oversees larger or more complex projects. OHP administers design review and issues Certificates of Appropriateness (COAs) when required.
San Antonio Development Services manages building permits and inspections. If your project needs a COA, Development Services will not finalize or issue certain permits until that COA is approved. At the state level, Texas disclosure rules still apply, so you must accurately disclose known facts and provide documents that back up your statements.
Many local decisions also reflect the Secretary of the Interior’s Standards for Rehabilitation, which emphasize retaining character‑defining features. Understanding this framework helps you predict what reviewers will likely approve.
Exterior projects that usually need a COA
Not all work triggers review, but exterior changes that affect historic character commonly do. Look for these categories when you prepare your listing:
- Demolition or removal of contributing features, including accessory structures.
- Additions or new construction, like porches or garages.
- Roof work that changes form or materials, including a new roofline.
- Exterior siding, trim, or cladding changes, such as wood to synthetic.
- Windows and exterior doors, especially changes to style or historic sash.
- Porches, balconies, and entries, including enclosures and railing changes.
- Fences, walls, gates, and driveway changes that alter visibility or character.
- Accessory structures and their placement on the lot.
- Site work that impacts context, like grading or removing historic hardscape.
- Mechanical equipment visible from public ways, such as roof‑mounted units.
- Signs and exterior lighting for commercial properties.
- Paint color may be reviewed on key facades in certain districts, so confirm with OHP.
- Work in the public right‑of‑way or removal of landmark trees may require added approvals.
What may be exempt or approved administratively
Some work can move quickly or may not require a full hearing. Still, confirm for your specific property.
- Interior work and ordinary maintenance that does not change appearance.
- Like‑for‑like exterior repairs or in‑kind replacement.
- Emergency stabilization with prompt notice to OHP. A retroactive COA may follow.
- Minor items that OHP staff can approve administratively.
Do a pre‑listing preservation check
Before you market the home, audit recent and past exterior work. Your goal is to answer, with documents, whether work needed approvals and whether it was completed and closed out. Use this quick process:
Schedule a pre‑application consult with OHP to confirm if a COA is needed for any visible changes and what documents they will want to see.
Run a permit check with Development Services using the address or known permit numbers. Note which permits are finaled and which remain open.
Walk the property exterior and compare it to any available historic photos, past listings, or plans. Look for changes to windows, doors, porches, siding, roof shape, and accessory buildings.
Identify any unapproved work. If needed, plan a retrospective COA or corrective path before listing.
Collect documents into a single Historic Compliance Packet for buyers and their lenders.
COA process and typical timing
Most projects follow one of two paths, with timing depending on scope:
- Administrative COA: OHP staff can approve routine or consistent work. Expect days to a few weeks.
- Full HDRC review: Complex changes, additions, or demolition go to a public hearing. Expect several weeks lead time for submittal, public notice, and the hearing date.
The steps are straightforward:
- Pre‑application meeting to confirm requirements.
- Application with plans, photos, materials, and a narrative.
- Staff review or scheduling for HDRC agenda.
- COA decision with conditions noted in the approval document.
- Building permit application and inspections. Permits are finaled once all conditions are met.
For planning your listing timeline, allow 4 to 8 weeks for straightforward items. Larger or contested proposals can take longer. Start early if a visible change might concern buyers, like window replacements or porch alterations.
What to include in your Historic Compliance Packet
A clean, complete packet prevents renegotiation and keeps lenders comfortable. Gather originals and digital copies of:
- Certificate of Appropriateness documents with dates, stamped scope, and conditions.
- Building permits, including permit numbers, issue dates, and final inspection sign‑offs.
- Approved plans and elevation drawings that match the built work.
- Contractor invoices and receipts, including change orders.
- Photo sets showing before, during, and after the work.
- HDRC staff reports or meeting minutes if there was a hearing.
- Correspondence with OHP and Development Services, such as emails or case numbers.
- Warranties or maintenance agreements for materials or systems.
- Any enforcement notices, citations, or pending applications.
How to disclose clearly to buyers
Texas disclosure rules require accuracy and clarity. Your buyer, their lender, and their insurer will appreciate specifics.
- In the Seller’s Disclosure, state whether a COA was required for exterior work and whether you obtained and finaled both the COA and any building permits. List COA and permit numbers and dates.
- Attach copies of the COA and finaled permits to the disclosure and upload them to MLS documents if allowed by MLS rules.
- Provide your Historic Compliance Packet at showings. Buyers can review faster and with more confidence.
- Use precise language instead of general statements. For example, “Window replacement completed 06/2024; COA #12345 issued 06/10/2024; Building Permit #67890 finaled 07/05/2024.”
- If a COA application is pending, note the filing date, the expected HDRC hearing date, and any known conditions.
If work was done without approvals
Do not hide it. Outline the facts and the path to resolution.
- Ask OHP about a retrospective COA. Outcomes vary and could include mitigation or restoration.
- Consider temporary stabilization if there is a safety concern, then follow with formal review.
- Be prepared to offer solutions during negotiations. Credits, escrow holdbacks, or a seller‑completed COA before closing can keep a deal moving.
- Disclose any enforcement actions and show your plan and timeline for compliance.
Deal structures that keep closings on track
When approvals are incomplete or timing is tight, you have options that allocate risk and keep the transaction fair:
- Seller completes COA and finalizes permits before closing. This reduces risk and supports a stronger price.
- Price credit or allowance to cover the buyer’s cost for approvals or restoration.
- Escrow holdback that releases funds once the buyer confirms COA and permit finalization.
- Buyer contingency period to review historic approvals and permits, with the right to renegotiate or terminate if unacceptable.
- Shared responsibility terms that define who will pursue a retrospective COA and who pays, with caps or timelines.
Red flags to investigate before listing
Watch for issues that commonly trigger delays or rework:
- Substantial exterior changes with no COA or permits in city records.
- Enclosed porches, removed columns, or window style changes without approvals.
- Open enforcement cases or unresolved notices.
- Mismatches between current conditions and approved plans.
- Additions that change massing, large accessory structures, or roofline changes.
Sample disclosure language you can adapt
Use these examples to make your disclosure precise and easy to verify. Replace the placeholders with your property’s details.
- “Exterior alterations to front façade, including window sash and porch columns, performed 05/2023. COA required. COA #____ granted 05/15/2023 with conditions A and B. Building Permit #____ finaled 06/07/2023.”
- “New rear accessory structure built without COA. COA application submitted 09/01/2024, Application #____. HDRC hearing scheduled for 10/20/2024. Buyer may assume risk of outcomes if closing occurs before final COA approval.”
Who to contact for clarity
Start with the city and your professional team. Having names, dates, and case numbers creates buyer confidence.
- City of San Antonio Office of Historic Preservation for pre‑application consults and COA requirements.
- San Antonio Development Services for permits and inspection status.
- HDRC agendas and staff reports to confirm hearing dates and conditions.
- Texas Real Estate Commission for the Seller’s Disclosure Notice and guidance on disclosure.
- Preservation‑experienced contractors, architects, or consultants who have worked in your district.
- A real estate attorney for addenda, escrow language, and complex compliance issues.
Keep your timeline seller‑friendly
A little preparation saves weeks of stress during escrow. Confirm whether exterior work needed a COA, close out any open permits, and present a complete Historic Compliance Packet from day one. Buyers feel more confident, lenders approve faster, and you protect your price during negotiations.
