Carrollton FAQ
Does Dallas County limit construction equipment noise?
No countywide rule exists. Texas counties lack general noise authority. Check your specific city ordinance, as Dallas, Irving, Garland and other cities each set their own construction hour limits.
What if I'm in unincorporated Dallas County?
Only Texas Penal Code disorderly conduct applies, requiring unreasonable noise. Call Dallas County Sheriff non-emergency line. Most of Dallas County is incorporated, so this is rare.
Dallas FAQ
When can construction crews start work in Dallas?
No earlier than 7:00 a.m. Monday through Saturday under Chapter 30. Sunday and holiday work requires a written variance from the Building Official, typically only granted for emergency utility or transportation projects.
How is the 75 dBA limit measured?
Code Compliance officers use a Type 1 or Type 2 sound-level meter at the residential property line nearest the construction site, averaged over a representative interval excluding brief impulse noises.
