Growth SignalU.S. Census Bureau estimates place San Marcos at 77,830 residents in 2025, up 14.9% from the April 2020 estimates base. The City’s own January 1, 2026 planning estimate is 91,082.
University DemandTexas State University reported a preliminary Fall 2026 enrollment of 47,513 students across its locations and programs, reinforcing San Marcos as a university-connected housing market.
Development CodeSan Marcos adopted a major update to its Land Development Code and Design Manual on June 16, 2026. Parcel screening should use the new 2026 code rather than older zoning assumptions.
Zoning / EntitlementsPlanning cases may involve zoning, subdivision, conditional use, alternative compliance, variances, site permits, watershed protection plans or public-improvement construction plans. The City recommends a pre-development meeting when requirements are uncertain.
City Property TaxThe adopted FY2026 City property-tax rate is $0.6515 per $100 of taxable value. For FY2027, the City currently lists a proposed rate of $0.651500 per $100, so the final adopted FY2027 rate should be confirmed before underwriting.
Water / WastewaterSan Marcos provides municipal water and wastewater service. Current inside-city utility rates are published by the City, and new development can also be subject to one-time water and wastewater impact fees.
Impact FeesSan Marcos completed a 2026 water and wastewater impact-fee update process. The City states that the amended impact-fee ordinance was approved in September 2026, so the current adopted fee schedule should be used for project underwriting.
Project FitSan Marcos is worth retaining for deeper site screening because of population growth, university demand and established development infrastructure, but compact-home feasibility must be confirmed against the 2026 code and exact parcel conditions.
Before land control or a JV agreement, verify zoning, permitted housing type, density, minimum lot/building standards, watershed and stormwater requirements, utility capacity, the current impact-fee schedule and all site-specific development approvals with the City of San Marcos.
