Historic Home Renovation in San Antonio: OHP Review and Approval

A historic home renovation in San Antonio starts with one question: is your house a City landmark, or does it sit inside one of the local historic districts? If it does, find out what the City's Office of Historic Preservation (OHP) has to review before you choose a single finish, because that review shapes your design, your material orders and your schedule.

Step 1: Confirm whether your property is designated

OHP's historic districts page lists 32 locally designated historic districts as of October 2026, including King William, Monte Vista, Dignowity Hill, Tobin Hill, Government Hill and Monticello Park. Individual landmarks can sit outside those districts. OHP's Explorer Map, linked from the OHP home page, lets you search by address for designation status and past approvals on file. Use it, or call OHP at 210-207-0035, before you sign a design contract. Historic zoning on a property appears as an H, HS, HE or HL designation.

OHP also points out that local historic districts are distinct from National Register Historic Districts, so check the local designation itself rather than relying on a National Register listing.

Ask, too, whether your lot is in a Neighborhood Conservation or Corridor District. DSD's No Permit Required list notes that even work needing no building permit, such as painting, new cabinets or replacing existing doors, can face design and material restrictions in a Historic, Neighborhood Conservation or Corridor District.

Step 2: Know what needs a Certificate of Appropriateness

OHP's Before Getting Started page says all exterior modifications and repairs on a property with a historic zoning overlay require a Certificate of Appropriateness (COA). That includes side yards, rear yards and areas the street can't see. Interior-only work with no changes to exterior windows or doors needs no OHP approval, though a permit from Development Services (DSD) may still apply.

In practice, plan on review for:

• Window and door repair or replacement
• Siding, trim, porch and masonry work
• Roofing changes
• Fences and site walls
• Additions and new accessory buildings

One common worry is paint. OHP's districts page says the City's Historic Design Guidelines do not limit paint color selection. Painting is still exterior work on a designated property, so ask OHP how your project should be handled before the crew starts.

Step 3: Administrative approval or a public hearing

There are two paths. OHP says minor projects can usually be approved by staff with a COA, and requests that qualify for administrative approval are processed without a hearing. Requests that don't qualify go to a public hearing before the Historic and Design Review Commission (HDRC). Properties in a district must comply with the City's Historic Design Guidelines, which City Council adopted and which cover maintenance, additions, site elements and new construction.

For hearing cases, OHP says applications are due 19 days before the meeting you are aiming for, and COAs are usually issued within 10 days after it, often sooner. Build that into your schedule before ordering windows, siding or custom millwork.

Applications are filed online through OHP's portal. Once you submit, OHP's Before Getting Started page says you will receive a confirmation email and a case manager will contact you by email or phone, with a stated target of one business day. OHP then tells you whether your application is complete or needs more information. As of October 2026, OHP's application page lists no COA fee for an existing single-family home. OHP's Before Getting Started page warns that work started without a COA may bring a Stop Work Order and a $500 post-work application fee. OHP asks for current color photos of every side of the structure, corner to corner, plus documents that show exactly what is proposed; Google images are not accepted.

Step 4: Find hidden conditions before you lock the scope

Older homes rarely match their paperwork. Before finalizing drawings, look for:

• Pier-and-beam foundations that need new supports or releveling
• Outdated wiring and galvanized or cast-iron plumbing
• Termite or water damage in sills, framing and subfloor
• Lead-based paint in homes built before 1978
• Materials that should be tested for asbestos before anyone disturbs them

On lead, EPA's Renovation, Repair and Painting rule requires anyone paid to disturb painted surfaces in a pre-1978 home, sole proprietors included, to be certified and to follow lead-safe work practices. Ask for the firm's certification before work begins. On asbestos, EPA says you can't tell whether a material such as floor tile, ceiling tile or old pipe wrap contains it just by looking, and recommends sampling by a trained and accredited asbestos professional before a renovation disturbs it (EPA asbestos remodeling guidance).

Small exploratory openings, made with OHP's rules in mind on the exterior, reduce mid-project surprises. Our site-visit scope worksheet gives you a room-by-room format for recording what you find.

Step 5: Decide repair or replace, feature by feature

Original wood windows, siding and porch details can often be repaired rather than replaced, and repair is usually easier to justify in design review. Decide one feature at a time. The photos you take now do double duty: they document conditions for your contractor and support your COA application.

Step 6: Sequence systems before finishes

A typical order:

1. Foundation and structural repairs
2. Roof and exterior weatherproofing
3. Rough-in electrical, plumbing and HVAC
4. Insulation placed so it does not trap moisture in old walls
5. Plaster or drywall, trim, flooring and paint

Routing new ductwork and wiring through plaster walls takes planning, so map chases, closets and attic paths early. Electrical, plumbing and HVAC work is performed, permitted and inspected by licensed trade contractors. If the project touches most of the house, planning a whole-home remodel in phases helps you decide what to open once and what can wait.

Tax incentives for a historic home renovation in San Antonio

A large renovation may qualify for a City tax incentive, so check before work starts. OHP's incentive programs page describes the Substantial Rehabilitation Tax Incentive for designated landmarks and properties in local historic districts:

• What counts: improvements that extend the life of the building, such as roofing, foundation, siding, electrical, plumbing, HVAC, structural and interior work.
• Threshold: the project must cost at least 30% of the property's Improvement Homesite Value as determined by the Bexar County Appraisal District.
• Residential options: a 10-year freeze of the City property tax line at the pre-improvement value, or 5 Zero/5 Fifty, with no City property taxes for five years and then five years assessed at 50% of the post-rehabilitation value.
• Scope of the savings: it applies only to the City of San Antonio line on your tax bill, not other taxing entities.
• Two applications: certification at the beginning stages of work, and verification once the project is done and all permits are closed. HDRC reviews both, and the exemption takes effect the following calendar year.
• Transfer: the incentive stays with the property for new owners.

OHP's page also lists a separate exemption for owner-occupied homes in newly designated local historic districts, and San Antonio Conservation Society grants for restoring structures at least 50 years old. The federal 20% rehabilitation tax credit is a different program: the National Park Service says owner-occupied residential properties do not qualify, because the credit is for income-producing buildings. Keep invoices, permits and photos organized from day one so the verification step goes smoothly.

What to ask before you hire for a historic project

• Have you prepared photos and scope documents for an OHP Certificate of Appropriateness?
• Will you show me repair options before recommending replacement?
• Is your firm EPA lead-safe certified for work in pre-1978 homes?
• Which City contractor registration covers this scope, Residential Building or Home Improvement?
• Which licensed trade contractors will perform and permit the electrical, plumbing and HVAC work?
• How will you document hidden conditions and price any changes before the work proceeds?

Permits after design review

Design approval and building permits are separate steps. DSD's contractor registration page says a Residential Building Contractor registration is required for remodeling that involves structural work, additions, foundation work and detached accessory buildings larger than 300 square feet; non-structural remodeling falls under the Home Improvement Contractor registration. DSD's Getting Started page adds that, on a hired-contractor project, licensed trade contractors request the trade permits and inspections. For plumbing only, DSD also permits a resident owner to obtain a permit for an existing homestead. The homeowner affidavit requires personal work without assistance, excludes business or rental property and requires City inspection.
