What can I build on this property?

It depends on the zoning district. The San Marcos Development Code (Ord. 2025-01, effective January 25, 2025) establishes conventional residential districts (FD, SF-R, SF-6, SF-4.5), neighborhood density districts (ND-3, ND-3.2, ND-3.5, ND-4, N-CM), character districts (CD-1 through CD-5D and PA), and special districts (CM, BP, HC, LI, HI, MH), plus seventeen Chapter 9 legacy districts (AR, SF-11, MR, D, DR, TH, PH-ZL, MF-12, MF-18, MF-24, MU, P, OP, NC, CC, GC, VMU) that remain mapped but frozen. Each current district page in Chapter 4 Article 4 lists its allowed building types, and the Land Use Matrix in Sec. 5.1.1.2 Table 5.1 marks each land use permitted, limited, conditional, or not allowed per district; legacy districts use the Table 9.1 matrix. Existing planned development districts follow their own adopting ordinances (Sec. 9.2.2.8). San Marcos zoning applies inside the incorporated city limits only; Texas counties do not zone, and ETJ parcels have no municipal zoning. A further Development Code update was adopted on second reading June 16, 2026 but is not yet published, so confirm current standards with the Planning Division at 512-393-8230 before design, purchase, leasing, or permitting decisions.
