Security guard contracts, explained
A guard contract is mostly a list of promises about shifts. Read it for who shows up, when, doing what, and how either side can end it.

The problem a contract solves
When a guard service goes wrong, the cause is rarely the guard. It is a missing detail: a shift nobody agreed to cover, a duty the company assumed was not part of the job, or a rate that rose without notice. A written agreement turns the conversation you had with a salesperson into terms both sides can point to.
In Houston, where property managers often run several sites with different needs, the contract is also how one company is held to the same standard across a portfolio of towers, warehouses and retail centers.
The parts to read first
Start with the scope of services. It should name each post, the hours it is staffed, how many officers cover it and whether each is armed or unarmed. Next read the post orders, which describe what the officer does at the post: checking visitors, walking the property, logging activity, or watching a gate. If post orders are not attached, ask for them.
Then read the reporting terms. A daily activity report, an incident report within a set period and a named contact for escalation are the things you will rely on. Ask where the reports are delivered and who at the company reviews them.
Money, notice and what happens when you leave
Look for the billing rate for each post, how holidays and overtime are charged, and how a rate change is announced. Look for the length of the initial term, whether it renews automatically and how many days of notice either side must give to end it. These clauses decide how easy it is to fix a bad fit.
Ask the company to provide current evidence of the insurance it carries and to name who is responsible if an officer is injured or if property is damaged. You are asking for documents, not making a legal judgment, and a reputable company will hand them over. If a clause is unclear, a Texas attorney can read it for you. Texas also requires that a guard company hold a license, so a contract with a company that cannot show one in the DPS license search deserves a pause.
Comparing two proposals fairly
Put the proposals side by side and compare the same lines: posts, hours, officers per shift, armed status, reporting, call-out coverage, term, notice and rate schedule. A proposal that is cheaper because it covers fewer hours is not cheaper. A proposal with a longer initial term should explain what you get for the commitment.
Once the lines match, the choice is usually clear. The result you want is a contract short enough to read, specific enough to enforce and flexible enough to adjust when a site changes. If you have not yet collected quotes, start with the hiring guide.

Questions Houston buyers ask
Should a guard contract be signed before the first shift?
Yes. Start the agreement and the shift schedule on the same date, so the written terms cover the first night as well as the rest of the term.
What are post orders?
Post orders are written instructions for what the officer does at a specific post: who to admit, where to patrol, what to log and whom to call. They keep expectations the same across shifts and across different officers.
Can I end a guard contract early?
That depends on the term and notice clauses. Read them before signing, and ask what the company charges, if anything, to end the agreement before the initial term is over.
Who is responsible for the officer's training?
The Texas Department of Public Safety sets the training levels for licensed officers, and the company that employs the officer arranges it. Ask the company how it documents training for officers placed at your site.
Do I need an attorney?
Many property managers sign a standard security agreement without one, but a Texas attorney can review unusual terms such as indemnity, a long initial term or automatic renewal.
