HPD Officer has been harassing my disabled 76 yr old retired VA nurse mother. Please help!

My mother owns a property inside the loop she bought in 1987. The Dept. of Neighborhoods with the City of Houston held a hearing earlier this month declaring it a dangerous building due to several structural violations.

I only found out about the hearing 48 hours in advance and drove from Austin to attend on my mother’s behalf. Before the hearing I secured a demolition company to knock down the house and provided the paperwork to the Dept. of Neighborhood’s attorney. They were thrilled I came prepared and had a plan and gave me 30 days to secure permits (already obtained) and 60 days to repair or demo the house (demo starts next week).

Since the hearing, an HPD officer has shown up to my mother’s house which is next to the aforementioned property, and threatened that they’ll give her tickets or take away the house if she doesn’t do something about it. Today he did it again but my mother got his name and number per my request. I give this guy a call and ask if he’s affiliated with the Dept. of Neighborhoods and he says no. He responds that he’s with HPD and they got a private complaint about a vacant house, so he’s taken it upon himself to tell my mother what could happen if it’s not resolved. I explain everything and inform him that he’s been intimidating my mother (perception is reality) and making her feel unsafe. I then kindly ask him to leave her alone as I’ll be in town next week to resolve everything, including transferring the property in my name. He became very combative and told me not to threaten him and that he can do what he wants and has a body cam and hasn’t done anything wrong.

I let him know that a lot of people have been trying to buy my mothers property from her over the years, and I wouldn’t be surprised if this was intended to intimidate and try and persuade her to sell. I then let him know I would be filing a complaint with HPD when I’m in town.

I haven’t had the best experiences with police in the past so thought I’d reach out here for help. Any advice navigating this situation would be greatly appreciated! Thanks everyone.

Edit: just want to add that when he continued to accuse me of threatening him, I let him know that asking him to leave my mother alone is protected free speech, and advised he brush up on constitutional rights/protections. Needless to say, he doubled down on his claims I was threatening him.
