Where is a single-family home allowed in Healdsburg?

Find your lot's zone on the city zoning map, then read its row. Every status below was read from the Healdsburg Municipal Code use tables (read October 2026). Base zones only. General information, not legal advice — check with the city before you apply.

Healdsburg's code calls this use “Single-family dwelling, detached”. 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.

• S1 also lists "Single-family dwelling, attached, one per lot, in the R-1-3,500 District" (P), and S7 MU "Single-family attached dwellings not part of a mixed use development" (P); attached rows are not used. R-1 table covers all R-1 districts (R-1-3,500 etc.).
• State law: State law lets most single-family lots add an ADU and a JADU (California ADU law) and a second home or a lot split under SB 9 (Gov. Code § 65852.21).
• Not covered here: Definitions (Chapter 20.28 Article IX) and use-specific regulations (HMC Chapter 20.20) are not in the packet; Overlays DC, HD, NEAP excluded (S13-S15). Overlay zones and specific plans can also change the answer.
