Do you need a building permit in Healdsburg, CA?

Healdsburg requires a building permit before constructing, altering, adding to or demolishing a structure, with limited exemptions under the adopted code.1 Healdsburg adopted the 2025 California Building Standards and Title 24, effective January 1, 2026, with city amendments possible.10

California’s owner-builder exemption concerns contractor licensing; the exemption does not make an otherwise required Healdsburg building permit unnecessary.8 Ask the Healdsburg Building Division to identify the application and inspection requirements for your proposed work before construction begins.3

Who issues building permits and inspections in Healdsburg?

The Healdsburg Building Division accepts building permit applications, reviews plans and inspects building-related work inside city limits.3 Reach the Building Division at 707-431-3346 or [email protected]; the counter is at 401 Grove Street Healdsburg CA, 95448.3

Healdsburg accepts online applications or paper applications, plans and documents at the Building Division front counter.3 Building-permit fee estimates depend on project value and/or square footage, and plan-review fees must be paid before review begins.11 Healdsburg does not schedule same-day building inspections, so arrange inspections before work is ready to be covered.312

Does Healdsburg have zoning, lot-size rules and setbacks?

Healdsburg administers its own Land Use Code, with district-specific use regulations and development standards; county zoning standards are not the standards for a parcel inside Healdsburg city limits.2 Ask the Healdsburg Planning Division for the parcel’s district, permitted residential use, minimum lot size and applicable setbacks before choosing a house plan.25

Healdsburg allows ADUs in districts permitting single-family or multifamily uses when a legally permitted primary dwelling exists or is proposed, subject to applicable standards.6 The maximum ADU size is 1,200 square feet, the maximum JADU size is 500 square feet, and standard interior side and rear ADU setbacks are 4 feet, subject to exceptions.6 Subdivision approval and map procedures apply before subdivided lots are sold.13

How do septic permits and private wells work inside Healdsburg?

Permit Sonoma administers non-standard septic operational permits within Sonoma County, including incorporated cities; that does not establish every requirement for a standard septic system in Healdsburg.414 California’s onsite wastewater policy addresses new and replacement septic systems through local permitting agencies.15 Ask Permit Sonoma’s Well and Septic Division about a proposed system or existing system’s repair, and ask Healdsburg Planning whether the parcel must connect to public sewer.165

Sonoma County well permits cover drilling, abandoning or deepening wells, including within incorporated areas, and can be issued only to licensed C-57 well-drilling contractors.9 Permit Sonoma’s Well and Septic Division can be reached at (707) 565-2849 or [email protected].16

Can you live in an RV, tiny home or manufactured home in Healdsburg?

We could not confirm Healdsburg’s private-land RV occupancy, temporary camping or tiny-home occupancy rules; ask the Healdsburg Planning Division about the specific structure and intended residential use before buying it.5 Healdsburg does have a conditional pathway for manufactured homes used as dwellings: the home must meet federal manufactured-housing standards, sit on a permanent foundation and satisfy exterior, roofing, utility and garage or carport requirements.7

Before occupancy of a mobile or manufactured home in Healdsburg, the owner must request Building Department certification for issuance of a certificate of occupancy.17 A manufactured home used as an ADU must also satisfy Healdsburg’s ADU standards.7 These manufactured-home provisions do not resolve the unconfirmed RV or tiny-home question; ask Planning for a determination for your proposed use.5

Building a home in Healdsburg: what are the steps?

  1. Ask Healdsburg Planning to confirm the parcel’s zoning district and the proposed dwelling’s development standards.25
  2. Submit the building-permit application, plans and documents to the Healdsburg Building Division online or at the front counter.3
  3. Obtain a project-specific fee estimate and pay applicable plan-review fees before review begins; slope-stability projects in the identified zones may also require geotechnical review.11
  4. Resolve City review comments and obtain the required building permit before construction starts.181
  5. Schedule construction inspections, leave work uncovered until inspected and approved, and obtain final approval to complete the project.1218

What should you check before buying land in Healdsburg?

For land outside Healdsburg city limits, use the Sonoma County guide for the county’s unincorporated-area building and zoning answers; Healdsburg administers its own zoning inside the city.19202 For a city parcel, ask Planning to resolve public water and sewer connection requirements and floodplain development requirements before committing to an off-grid design; we could not confirm those city requirements.5

Healdsburg requires an encroachment permit for work within public rights-of-way, public easements or public property, so ask about the street connection when planning driveway work.21 Sonoma County’s soil figures are countywide, not a Healdsburg parcel assessment: only 2.8% of soils are rated not limited for conventional septic drain fields, which supports obtaining a site evaluation rather than assuming septic is impossible.22

Watch-outs

  • Healdsburg ADUs may not be converted to residential visitor lodging; do not assume an ADU can supply short-term rental income.23
  • We could not confirm a Healdsburg agricultural building exemption or minimum dwelling size; ask the City Building and Planning divisions before relying on either.35
