Do you need a building permit in Solvang, CA?

Solvang requires a building permit before building, enlarging, altering, repairing, moving, demolishing or changing the use of a building or structure, unless the project is specifically exempt.1 Regulated electrical, gas, mechanical and plumbing work also falls within the city's building-permit instructions.1 Work must wait until the city issues the building permit.1

Solvang owner-builders may obtain building permits, but the city may require additional forms or verification.7 Owner-builder status does not remove the requirement to obtain the building permit before work begins.7

Who issues Solvang building permits, and how do you apply?

The Solvang Building Division accepts building-permit submittals by email at [email protected]; application help is available at (805) 688-5575.1 Use the city's project-specific checklist and prepare the application, plans, calculations and checklist items as a single PDF packet or clearly labeled PDFs.1

Building reviews the submittal, and Planning, Public Works and Fire may also review the project as needed.1 Some Solvang projects require stamped structural or other engineered documents.1 Send revised PDFs addressing review comments, then follow the city's issuance instructions and pay remaining fees before construction.1 Inspection instructions are supplied when the building permit is issued.1

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

Solvang administers city zoning inside city limits, so the parcel's residential district matters when planning a home.2 Solvang's R-1 Residential Low Density district has a minimum lot size of 20,000 square feet; ER-1 Estate Residential has a minimum of 1 acre.45

In Solvang R-1, minimum setbacks are 20 feet in front, 10 feet at the side, 15 feet at the street side and 10 feet at the rear, measured from property lines.9 In ER-1, the corresponding setbacks are 25, 10, 15 and 25 feet.9 Both districts have maximum lot coverage of 30% and maximum building height of 25 feet, with height measured under the city's prescribed method.1011 We could not confirm a minimum primary-dwelling floor area; ask Solvang Planning about the proposed home.12

How do septic permits and water connections work inside Solvang?

Every new or replacement septic system in Santa Barbara County requires a permit through the applicable local jurisdiction or the Central Coast Water Board.3 Systems within Santa Barbara County jurisdiction that fall outside the approved Local Agency Management Program or applicable Tier 1 requirements need Central Coast Water Board permitting.13 Ask County Environmental Health Services to confirm the local permitting arrangement for a Solvang parcel before planning an onsite system.14

Solvang ADUs must connect to city water and sewer, so an ADU proposal cannot assume an independent septic solution.6 California also requires a permit from the applicable local environmental health agency or water district before constructing, modifying or destroying a water well.15 We could not confirm the specific well-permit office for a Solvang address; ask Environmental Health Services to identify the enforcing agency.14

Can you live in an RV or tiny home on Solvang land?

California treats RVs as vehicles not intended for permanent dwelling occupancy; unless a local ordinance allows otherwise, RV occupancy generally is limited to regulated mobilehome or special occupancy parks.16 We could not confirm a Solvang exception allowing residential RV use on an ordinary private lot; ask Solvang Planning about the parcel and any proposed stay during construction.12

California tiny-home occupancy depends on an approved classification, compliance with the applicable standards and approval of the location.8 We could not confirm a Solvang provision specifically permitting tiny-home occupancy; ask Planning which housing classification and land-use approval would apply.12 Solvang allows ADUs subject to its residential rules, requires city water and sewer connections, and prohibits using an ADU as a short-term rental.6

What are the steps before building a home in Solvang?

Start with Solvang Planning to confirm the parcel's zoning district and discuss the proposed use; Solvang administers zoning inside city limits.212 For land outside city limits, use the Santa Barbara County guide: the county building-permit rule concerns unincorporated land.17

Before settling the home location, resolve flood constraints: Solvang generally prohibits floodway development other than the stated exceptions unless qualifying offsetting improvements are provided.18 In the floodway fringe, development may be permitted if creek setbacks are met and finished floors exceed the projected flood elevation.18

Next, assemble and email the city building-permit checklist packet, address review comments and obtain the issued building permit before starting work.1 Build to the approved plans and schedule the required building inspections.1 Ask the Building Division what occupancy approval the finished home needs; we could not confirm when Solvang requires issuance of a certificate of occupancy.1

Watch-outs

  • Solvang ADUs require city water and sewer connections and cannot be used as short-term rentals.6
  • Solvang floodway and floodway-fringe restrictions can change where a home can be built.18
  • We could not confirm Solvang driveway-access requirements or an agricultural building-permit exemption; ask city Planning and Building before designing access or a farm structure.121
