NO! The Fourth Amendment to the United States Constitution, as well as Article I Section 9 of the Texas State Constitution, gurantees that all persons shall be free from unreasonable search and seizures. As a general rule, the only way that an officer may gain access to your residence is either by first obtaining a search warrant or by obtaining permission from a resident. There are some limited exceptions to this general rule (i.e., contraband seen in plain view, exigent circumstances, etc.); however, if an officer asks you to give him written or verbal consent to search your residence you always have the right to say no. After you deny an officer consent to search, some officers will state that they can just simply go and obtain a search warrant and that you should just go ahead and give them consent to speed up the process. If this occurs, just politely tell the officer that you are in no hurry and that he will just have to go get that search warrant.
Your home is your castle and you have the right to protect what it contains. If you grant written or verbal consent for an officer to search your residence and illegal contraband is found, you may have seriously hindered a lawyer’s ability to successfully defend your case.
