Two instruments, two statutes, two questions
A municipal building inspection and a private home inspection are not a strong and a weak version of the same examination. They are separate instruments, created by separate bodies of law, answering different questions.
Set the definitions side by side and the gap is visible in the drafting. The model International Residential Code states its purpose at R101.3: to provide “minimum requirements to safeguard the public safety, health and general welfare…”. Texas Occupations Code §1102.001 defines a real estate inspection as “a written or oral opinion as to the condition of the improvements to real property, including structural items, electrical items, mechanical systems, plumbing systems, or equipment.”
Minimum requirements against an opinion as to the condition. Notice what is absent from the purpose clause: durability, workmanship, longevity, comfort, resale value, the absence of defects. The code is a floor beneath which construction may not fall, not a description of a good house.
| Municipal building inspector | TREC home inspector | |
|---|---|---|
| Credential | ICC certification, plus employment by the city | State licence, Occupations Code ch. 1102 |
| Works for | The city, enforcing its ordinance | The client, under contract |
| Governed by | The adopted code | 22 TAC §§535.227–535.233; REI 7-6 |
| Question answered | Does this permitted work comply with the adopted code? | What is the condition of the accessible systems today? |
Where the municipal inspector's authority comes from
A municipal building inspector is not a free-standing professional. The authority runs down a chain: state statute, the model code it adopts, the city's ordinance, the building official, then the field inspector.
Texas Local Government Code Chapter 214, Subchapter G is the root. §214.212(a) adopts the International Residential Code as it existed on May 1, 2012 as the municipal residential building code of this state; §214.212(c) lets a municipality adopt local amendments.
The point for a buyer is that state law sets a floor, not a ceiling. Everything newer that Plano enforces is there because Council adopted it by ordinance, working from regional amendments developed by the North Central Texas Council of Governments and reviewed by Plano's Building Standards Commission. The 2024 I-Codes and the 2023 NEC took effect on 1 August 2025 under residential Ordinance 2025-6-15; the prior cycle arrived under Ordinance 2022-1-17 effective 1 February 2022.
At the bottom of the chain sits Plano's amendment to IRC R103.1, creating the Building Inspections Department and its building official. Every field inspector's authority is delegated from that office, and it is authority to enforce a document — not to evaluate a house.
Scope is defined by the permit, not by the house
If one sentence carries this entire subject, it is Plano's own, from the City's Customer's Guide to the Building Permit Process:
“A list of required inspections will be provided with the permit when issued.”
The scope of a City of Plano inspection is not the house. It is a list, attached to a permit, covering the work that permit authorises. A re-roof permit produces roof inspections; a bathroom remodel permit produces inspections of that bathroom. Neither produces an opinion on the foundation, the panel, the ductwork, the windows, the drainage or the attic, because none of that appears on the list. And the City publishes no per-permit checklists, so scope is defined by a document only the permit holder ever sees.
Notice what the inspection points have in common. Footing and foundation, before concrete. Slab, after reinforcing steel is in place but before the pour. Framing, after the roof deck and bracing are up. Fire-resistance-rated penetrations, which “shall not be concealed from view until inspected and approved”. Every one is timed to catch something just before it becomes irreversible, and once a checkpoint passes the system's interest in that assembly ends permanently.
Nor does the City initiate any of it. Nobody is monitoring a house: somebody with a permit asks, and an inspector comes out.
What a TREC licence authorises, and the eleven words that define it
Texas Occupations Code Chapter 1102 governs real estate inspectors, and the Commission's Standards of Practice sit at 22 TAC §§535.227–535.233. Note the word in every one of those rule titles: Minimum inspection requirements. The Standards are a floor for the inspector as the code is a floor for the builder.
§535.227(a) defines the instrument. A real estate inspection is “a limited visual survey and basic performance evaluation of the systems and components of a building using normal controls” providing information on the general condition of a residence at the time of inspection, and it “is not intended to be a comprehensive investigation or exploratory probe to determine the cause or effect of deficiencies.” It does not require specialised equipment — thermal imaging, moisture meters, gas detection — or specialised procedures such as environmental testing, elevation measurement or destructive testing.
The definitions in §535.227(b) do quiet, heavy work. Deficiency is a two-branch test: a condition that adversely and materially affects performance, or constitutes a hazard to life, limb or property.
Subsection (d) lists what an inspector is not required to inspect, to report, or to determine. Among the last group, at §535.227(d)(3)(F)(vi), is the single most important citation on this subject. An inspector is not required to determine, as to any system or component, its “compliance with any code, listing, testing or protocol authority.”
A home inspection is not a code inspection. It is not a lesser code inspection, or an unofficial one. It is a different instrument, and the rule says so in eleven words. TREC makes the same point in its own guidance: “The Standards of Practice do not require inspectors to inspect to today's code.” Rule text: 22 TAC §535.227.
The mandated report, and why REI 7-6 has no pass box
Texas does not leave the deliverable to the market. 22 TAC §535.223 adopts Property Inspection Report Form REI 7-6 by reference and requires it for inspections performed for a prospective buyer or seller of a substantially complete one-to-four family property, and software versions must reproduce it verbatim.
The exceptions connect back to the city. REI 7-6 is not required for re-inspections for the same client, for builder quality-control inspections, for buildings that are not substantially complete, or for lender or governmental inspections. TREC's own rulebook puts governmental inspections in a different category from the consumer regime.
One structural feature deserves its own sentence. REI 7-6 has four boxes — Inspected, Not Inspected, Not Present, Deficient — with any Deficient item explained in writing. It has no pass box and no fail box. It cannot render a verdict, because the instrument has no field for one. A municipal inspection result, by contrast, is binary and recorded as such. A buyer asking “did it pass?” is asking something the private report is structurally incapable of answering, and something the city's record answers only about the permitted work.
Credentials: ICC certification is not a TREC licence, in either direction
A municipal inspector's qualification is typically certification by the International Code Council, a non-governmental code-development organisation; the residential examinations are B1 Building, E1 Electrical, M1 Mechanical and P1 Plumbing, which together earn the R5 Residential Combination Inspector designation. The B1 exam shows what is tested: sixty multiple-choice questions, two hours, open book, weighted toward wall construction, footings and foundations, and public safety. There is no section on deterioration, none on diagnosing an existing building, none on reporting to a consumer. ICC describes the role as inspecting “to determine compliance with the various Building Codes and Standards adopted by his / her jurisdiction.”
Texas licenses some inspection trades directly — Occupations Code §1301.351(b) provides that “a person may not serve as a plumbing inspector unless the person is licensed under this chapter as a plumbing inspector.” For general building inspection, the qualification cities rely on is ICC certification, and the Legislature itself uses that benchmark. House Bill 14 in 2023 created Local Government Code Chapter 247, effective 1 September 2023, allowing an applicant to use a qualified third party when a regulatory authority misses a 15-day deadline on a development document or a required inspection. It defines who qualifies: a person certified to inspect buildings by the International Code Council; a building inspector employed by a regulatory authority or another political subdivision; or an engineer licensed under Chapter 1001, Occupations Code. When the Legislature had to say who is competent to perform a code inspection in a city's place, it named ICC certification and professional engineering licensure. It did not name a Chapter 1102 real estate inspector licence.
The passed-inspection fallacy, refuted by the code itself
The claim is familiar: the city inspected this house and it passed, so it must be sound. The most striking answer is that the model code refutes it three separate times, in its own text.
- On permits, R105.4: “The issuance or granting of a permit shall not be construed to be a permit for, or an approval of, any violation of any of the provisions of this code or of any other ordinance of the jurisdiction.”
- On inspections, R109: “Approval as a result of an inspection shall not be construed to be an approval of a violation of the provisions of this code or of other ordinances of the jurisdiction.”
- On certificates of occupancy, R110.3: issuance “shall not be construed as an approval of a violation of the provisions of this code or of other ordinances of the jurisdiction.”
The permit does not bless a violation. The passed inspection does not bless a violation. The certificate does not bless a violation. The drafters wrote the same disclaimer at every point where a homeowner might mistake a municipal approval for a guarantee: the code anticipated exactly this fallacy. None of the three is amended away by Plano's ordinance.
Around that sit the other reasons. Compliance means the work is not below the floor set at R101.3, and says nothing about how far above it the work sits. An inspection is a point in time, and has never claimed to be an exhaustive examination of every component.
The honest summary: a passed city inspection means that on a particular day, the work authorised by a specific permit was found to comply with the minimum requirements of the code edition then in force. It is not a statement about the rest of the house, about anything built before or after, or about condition today.
Grandfathering: the code applies to work, not to a standing house
This is the idea that makes the rest coherent, and its root is a single subsection. Local Government Code §214.212(b): “The International Residential Code applies to all construction, alteration, remodeling, enlargement, and repair of residential structures in a municipality.”
Every one of those is a verb describing work. The code attaches to activity, not to existence; it does not, by its own terms, apply to a house merely standing there. The model code agrees: the legal occupancy of a structure existing when the code is adopted may continue without change, and alterations must conform to what is required for new work without requiring the existing structure to comply with all of the requirements of this code.
Two rules that sound contradictory and are not. A standing house does not have to be upgraded when the city adopts a new code — Plano's 2025 adoption of the 2024 IRC imposed nothing on a 1975 Plano house. And new work must meet the current code, but only the new work. So a 1975 Plano house may legally keep its ungrounded two-prong outlets. No later adoption required a retrofit.
Any house altered over decades is therefore a stratified object — a 1975 core, a 1994 addition, a 2007 roof, a 2019 bathroom, each built to a different rulebook, each legal, all under one roof. There is no single “code” for a house touched more than once, which is why the permit record's dates matter so much.
One frequent point of transaction conflict follows. A TREC inspector may report a missing GFCI as Deficient on REI 7-6 regardless of the home's age — a reporting requirement under TREC's rules, resting on the two-branch definition of deficiency, not on a code citation. The “D” identifies a safety gap; it is not an accusation that the house violates anything. “Legal” and “safe by current standards” are two different questions, decided by two different documents. Statutory text: Local Government Code ch. 214.
Common questions
Does a city building inspection cover the whole house?
No. Plano's Customer's Guide to the Building Permit Process states that a list of required inspections is provided with the permit when it is issued. The scope is that list, covering the work the permit authorises. A re-roof permit produces roof inspections; a bathroom remodel permit produces inspections of that bathroom. Nothing outside the permitted scope is looked at, and the City does not publish per-permit checklists.
Is a TREC home inspector checking whether a house meets code?
No, and the rule is explicit. Under 22 TAC §535.227(d)(3)(F)(vi), a licensed inspector is not required to determine, as to any system or component, its “compliance with any code, listing, testing or protocol authority.” TREC's own guidance says the Standards of Practice do not require inspectors to inspect to today's code, and that inspectors are not required to research codes and ordinances. The inspection documents condition, not compliance.
The house passed every city inspection. Doesn't that mean it is sound?
It means that on a particular day, the specific work authorised by a specific permit was found to comply with the minimum requirements of the code edition then in force. The model code says so itself three times over: an approval as a result of an inspection “shall not be construed to be an approval of a violation,” and the same disclaimer appears for permits at R105.4 and for certificates of occupancy at R110.3.
Why is a 1975 Plano house allowed to have ungrounded outlets?
Because the code applies to work, not to a standing building. Local Government Code §214.212(b) states that the residential code applies to “construction, alteration, remodeling, enlargement, and repair” — all verbs. Adopting a new code cycle in 2025 imposed nothing on a house built under the rules of 1975. That house is legally nonconforming, not in violation, and no municipal process would come and inspect it.
Can a licensed home inspector do a city code inspection instead?
The Texas Legislature answered this when it created Local Government Code ch. 247 in 2023. A qualified third-party inspector is a person certified to inspect buildings by the International Code Council, a building inspector employed by a regulatory authority or another political subdivision, or an engineer licensed under Occupations Code ch. 1001. A TREC real estate inspector licence under Occupations Code ch. 1102 is not on that list.
What report is a Texas home inspector required to use?
Property Inspection Report Form REI 7-6, adopted by reference at 22 TAC §535.223 for inspections performed for a prospective buyer or seller of a substantially complete one-to-four family property. Software versions must reproduce the standard text verbatim. The exceptions include re-inspections for the same client, builder quality-control inspections, buildings that are not substantially complete, and lender or governmental inspections.
Why doesn't the inspection report say whether the house passed?
Because the mandated form has no such field. REI 7-6 offers four boxes — Inspected, Not Inspected, Not Present and Deficient — with each Deficient item explained in writing. A municipal inspection result is binary and is recorded that way in the permit system; a private report is a description of observed condition, and the instrument was never designed to render a verdict.
