Zones where a single-family home can go
Lathrop's code calls this use “One-family dwellings”. Each row links to the use table it comes from. A zone marked “see note” has a condition in the code, for example upper floors only or a larger lot.
| Zone | Status | Code |
|---|---|---|
| UR Urban Reserve | Allowed — see note Note C: A one-family dwelling in areas designated by the general plan for low density or medium density, provided that the site meets the property development standards and other requirements of that residential zoning district which is most appropriate for the general plan density designation involved; | § 17.24.020 |
| R One-Family Residential | Allowed | § 17.32.020 |
| RM Multifamily Residential | Allowed — see note Note A: One-family dwellings limited to: 1. A single-family dwelling replacing an existing single-family dwelling on a one for one basis, 2. A single-family dwelling on an existing lot of 8,000 square feet or less, or 3. Single-family dwellings that are part of a housing development with the majority of units affordable to extremely low, very low, and/or low income households; | § 17.36.020 |
