Summary
Farmersville caps how much of a residential lot a house and its accessory buildings can cover, from 20 percent in the Agricultural District up to 65 percent for attached single-family lots in SF-3. Section 77-61(c) applies these Section 77-52 and 77-53 district limits to both lot coverage and floor area ratio citywide.
(3)Area, yard and bulk requirements. ... Minimum Lot Area 7,200 sq. ft. Minimum Lot Width 60 feet. Minimum Lot Depth 100 feet. Minimum Front Yard 30 feet. Minimum Side Yard Interior Lot 10% of lot width; minimum 6 feet. Corner Lot See section 77-63. Minimum Rear Yard 10 feet. Maximum Lot Coverage 45%. Maximum Height Two stories, 35 feet. Minimum Floor Area per Dwelling Unit 750 square feet. ... (c)Lot coverage and floor area ratio. The maximum percentage of any lot area which may hereafter be covered by the main building and all accessory buildings and the maximum ratio of the floor area to the total area of the lot or tract on which a building is located shall not exceed the regulations specified in section 77-52 and section 77-53, except where an existing building at the effective date of the ordinance from which this article is derived may have a greater percentage of lot coverage or a higher floor area ratio than herein prescribed, such building shall be considered a conforming structure.
Full Breakdown
Section 77-61(c) sets the general rule: the percentage of any lot that the main building and all accessory buildings may cover, and the ratio of floor area to lot area, cannot exceed the limits specified in Sections 77-52 and 77-53 for that property's zoning district, though a building that already exceeded the limit before the current ordinance took effect is treated as a conforming structure rather than forced into compliance. Those district tables set the actual numbers: the Agricultural and Estate Development districts cap lot coverage at 20 percent, Single Family Dwelling-1 at 40 percent, Single Family Dwelling-2 at 45 percent, Two Family Residence at 50 percent, and Single Family Dwelling-3 varies by lot type, from 50 percent for a standard detached lot up to 55 percent for a zero-lot-line lot and 65 percent for an attached single-family lot.
Multifamily and non-residential districts carry their own separate maximum lot coverage figures under Section 77-53. Because the cap covers accessory buildings along with the main house, an owner adding a garage, workshop, or accessory dwelling unit under Section 77-66 must keep the combined footprint of house plus outbuildings under the district ceiling, not just the house alone.
Violations & Fines
Building or expanding a structure that pushes total lot coverage past the Section 77-52 or 77-53 limit for that zoning district violates Section 77-61(c). The building official can deny or revoke a building permit for plans that exceed the cap, and violations of Chapter 77 carry the general penalty under Section 1-15.
