Demolition permits are the most underused lead source in Houston residential construction, and one of the most underused in commercial. The reasoning is straightforward: if someone is paying to tear a structure down, they have already decided the existing structure is worth less than what's going up next. The demolition is a financial commitment to a future build.
Houston issues somewhere between 350 and 500 of these permits a month in normal conditions. Each one is publicly indexed within about 48 hours. The owner is identified. The address is identified. And on roughly seven out of ten residential demos, the rebuild GC has not yet been selected.
That's a lot of high-confidence early signal sitting on a public-records site that almost no contractors check on a weekly cadence. Here's how to find them, and how to be the first GC the owner hears from about what's next.
Why demo permits are the cleanest rebuild signal
Three reasons.
First: the intent is unambiguous. If you're paying to demolish a structure, you have decided that the existing structure is worth less than what you're going to put in its place. There's no maintenance interpretation, no "we might renovate." The demolition is a financial commitment to a future build.
Second: the timeline is consistent. In Houston, the median elapsed time from demolition permit issuance to first BLDG permit on the same parcel is about 4.5 months. The 25th percentile is 2 months; the 75th is 9 months. That's a tight, predictable window for a sales motion.
Third: the GC almost certainly hasn't been selected. About 70% of single-family demolitions in Houston are pulled by the homeowner or the demo contractor, not by the eventual rebuild GC. The owner has not yet had the architecture conversation, the cost conversation, or the GC conversation. You are early. Genuinely early.
Where Houston publishes demolition permits
Same place as BLDG permits, with a different filter. The City's permit search at cohweb.houstontx.gov supports a permit-type filter; setting it to DEMO returns every demolition permit, sortable by date.
What to know about the data:
- The full demolition permit set is published in roughly real time — usually within 48 hours of issuance.
- Each record has the parcel address, the applicant, the demo contractor, and the structure square footage being demolished. The owner of record is queryable via HCAD against the parcel.
- Commercial demos and residential demos are not separated by default. You filter by structure type or by valuation (commercial demos almost always have higher fees).
- Houston issues about 350–500 demolition permits a month in normal conditions. After hurricane events, the number spikes to 1,200+, mostly clustered in flood-affected zip codes.
The mailing-address trick
Here's the thing about demolition permits that almost nobody figures out on their first pass: the parcel address on the permit is the address being demolished. It is not where the owner lives. If you mail a letter to the demolished address, you're mailing it to a pile of rubble.
The owner's actual mailing address — where they want their tax bill to go — is on the HCAD record for the parcel. Cross-reference the demo permit address against the HCAD owner-mailing field and you get the owner's actual address. On commercial work where the owner is an LLC, the LLC's registered-agent or principal address is on the Texas Secretary of State filing.
This single step — joining the demo permit to the HCAD mailing address — is what makes the difference between an 11% response rate and a 1% response rate. Most lead-list products don't do this join, which is why most lead-list contact info is useless.
How to time the outreach
A few rules worth following on the outreach itself:
- 01 ·Wait 30 days after issuance. The owner is usually too busy with the demo logistics in the first month. They have not yet started shopping rebuild contractors.
- 02 ·Lead with the project, not yourself. Reference the address, what you observed about it (size, lot orientation, prior structure), and a specific take on what makes the lot interesting. "I noticed the demo on Bissonnet last month and the corner setback looks unusual" is much more effective than "we build custom homes."
- 03 ·Use mail, not email. The mailing address is well-indexed. The email isn't. Also, a physical letter on real paper from a local builder is rare enough in 2026 that it stands out.
- 04 ·Send the second touch at 90 days. By then they've had at least one architect conversation. Your second letter — referencing that they've probably been talking to people — lands at a different point in their decision cycle.
Commercial demos are a different game
Everything above applies to residential. Commercial demolitions — strip mall teardowns, office building demos, industrial site clears — are a smaller volume (60–90 a month in Houston metro) but each one tends to signal a much larger rebuild.
On the commercial side, the demo permit is often pulled by the new owner's environmental consultant or by the prior owner clearing the site before sale. Either way, the public record gives you the parcel, and a quick HCAD ownership-history check tells you whether the parcel transferred recently. A commercial parcel that changed hands in the last 12 months, was then demolished, and sits with an LLC owner is the highest-confidence signal in this entire category.
If you're a sub trade, this is also a useful signal — the rebuild GC won't be selected for another 3–9 months, but the architect often will be. I wrote about how subs use this signal to get on the architect's specifications, which is the highest-leverage sub-trade move in commercial construction.
The honest limitation
Demolitions don't all rebuild. About 18% of Houston demolitions in 2023–2024 resulted in a parcel that's still vacant 24 months later. The owner ran out of money, the financing fell through, the owner sold the parcel as cleared land to a developer who hasn't filed yet.
This is fine. The cost of a hand-written letter is low; the cost of a missed real project is high. Mail to every demo. Watch which ones move. The cost of the false positives is dwarfed by the value of being early on the real ones.
