Flower Mound requires owners of vacant lots to maintain grass below 12 inches and keep the property free of weeds, debris, and stagnant water under Chapter 30 of the Code of Ordinances. Texas Local Government Code Section 214.902 grants municipalities authority to require mowing and weed abatement on unimproved lots and to perform the work at the owner's expense if they fail to comply after notice. The town may mow non-compliant lots and assess all costs against the property as a lien. For properties with repeated violations during the same calendar year, the town may file a standing authorization with Denton County that permits future mowing without providing additional notice to the owner for each occurrence. Vacant lots near residential neighborhoods receive heightened enforcement attention due to fire risk during North Texas dry summer months and the impact of unmaintained parcels on surrounding property values.
Under Chapter 30 of the Flower Mound Code of Ordinances and Texas Local Government Code Section 214.902, owners of vacant and unimproved lots must maintain the property in a condition that does not create a health hazard, fire risk, or aesthetic nuisance to the surrounding community. Grass and weeds must not exceed 12 inches in height at any point on the property. Lots must be kept free of accumulated debris, refuse, rubbish, discarded materials, and stagnant water that may harbor mosquitoes or other disease-carrying pests. Dead vegetation, brush piles, and fallen tree limbs must be removed promptly to reduce fire hazards. The enforcement process begins when the town sends written notice to the property owner of record as identified through Denton County Appraisal District tax records, providing a 10-day compliance period from the date of mailing. If the owner fails to mow or clear the lot within the 10-day notice period, the town may perform the work using town crews or contracted mowing services and assess all costs against the property as a lien under Section 214.902(d). The lien is filed with the Denton County Clerk's office and attaches to the property, meaning it must be satisfied upon sale or transfer of the parcel. For properties that receive multiple violations during the same calendar year, the town may file a notice with Denton County under Section 214.902(c) that authorizes the town to perform future abatement work without providing additional written notice to the owner for each subsequent occurrence during the remainder of that calendar year. This streamlined enforcement mechanism is particularly useful for out-of-state property owners or investment property holders who are difficult to reach. Denton County Appraisal District records are used to identify current property owners and mailing addresses for all enforcement correspondence. Vacant lots adjacent to residential neighborhoods and school zones receive particular enforcement priority due to the elevated fire risk during North Texas dry summer months, when temperatures routinely exceed 100 degrees and vegetation becomes highly flammable. Additionally, the negative impact of unmaintained vacant parcels on surrounding property values is a frequent concern raised by residents and HOA boards in Flower Mound's master-planned communities.
Failure to maintain a vacant lot is a Class C misdemeanor with fines up to $500 per offense. Each day the violation continues after the compliance deadline constitutes a separate offense. The town may mow or clear the lot and place a lien for abatement costs, which typically range from $150 to $500 per mowing depending on lot size and vegetation density. Administrative fees are added to the lien amount.
