Height caps by district under the current code: FD and SF-R allow 2 stories and 40 feet; SF-6, SF-4.5, ND-3, ND-3.2, ND-3.5, CD-2.5, and CD-3 allow 2 stories and 35 feet; ND-4 and N-CM allow 3 stories and 45 feet; CD-4 allows 3 stories and 50 feet; CD-5 and CD-5D allow 5 stories and 75 feet but also require a 2 story, 24 foot minimum, and buildings in the downtown historic district within CD-5D are capped at 3 stories; CM, HC, LI, and HI allow 4 stories and 62 feet; BP allows 3 stories and 36 feet. Legacy districts are capped by the Sec. 9.1.1.1 table, generally 2 stories for single family and 4 stories for multifamily, MU, P, and VMU, with stories limited to 14 feet floor to ceiling. Accessory structures are typically capped at 24 feet. 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.
