Before You Invest in Plans or Permits
In San Marcos, small zoning interpretations and development standards can significantly influence unit size, parking requirements, and allowable configurations. Particularly in neighborhoods near transit corridors and hillside areas.
A property-specific feasibility review determines what your lot can legally support under current City regulations before design begins.
