Mansfield FAQ
Do I need a permit to add fill dirt to my Mansfield yard?
Small quantities of fill for landscaping typically do not require permits. Fill exceeding 250 cubic yards, or any fill that changes drainage to affect neighbors, triggers a grading permit and drainage plan.
Can my neighbor regrade to drain water onto my lot?
No. Texas law prohibits property owners from altering drainage in ways that cause injurious surface water flow onto adjoining lots. Disputes can involve code enforcement and civil court action.
North Richland Hills FAQ
My neighbor's new patio is flooding my yard in NRH. What can I do?
File a complaint with NRH Code Compliance at (817) 427-6650. The city can enforce drainage easement rules and positive drainage requirements, though pure cost disputes are civil matters between neighbors.
Do I need a permit to regrade my backyard?
Minor regrading (less than 50 cubic yards, outside easements, no change to drainage patterns affecting neighbors) typically does not need a permit. Larger projects or work near easements requires a grading permit.
