The property you are proposing to build upon must be platted and zoned for residential use. Since the City has a variety of zoning districts, the first step is to verify that the zoning of your land allows for residential use. For more information please see the Examples of Permitted Uses in Zoning Districts or refer to the UDC (Chapter 35 Article III, Sec 35-310.01, Tables 311-1/311-1a).
Please be aware that for each zoning district, your project will need to comply with the required building setbacks: the minimum distance from the property lines that a structure must be located. For more detailed information regarding these requirements please refer to the UDC Chapter 35, Article III.
If you have a question about your zoning designation, contact Development Services’ Call Center at 210.207.1111.
If you are unsure if your property is platted correctly, contact the Land Development Division at 210.207.0121.
For information regarding a zoning verification letter as well as the application, please go to Zoning Verification Letters.
