Do you need a building permit in Santa Maria, CA?

Santa Maria requires a building permit for work regulated by its adopted building code, including building, structural, paving, striping and signage work; specified residential work may be exempt.1 Ask the City Building Division to classify the proposed work before treating an accessory building as exempt.1 California’s statewide building standards apply to applications submitted on or after January 1, 2026, using the 2025 code edition.10 California’s owner-builder exemption concerns contractor licensing and does not remove Santa Maria’s building-permit requirement.81

Who handles Santa Maria building permits and zoning questions?

For Santa Maria building-permit routing, plan-check status, building-permit history and fee estimates, contact the City Building Division’s Permit Processing staff.11 The City’s building-permit page directs property-zoning questions and discretionary planning approvals to the Planning Division.11 Santa Maria Planning reviews zoning and subdivision applications against the General Plan, Specific Plans and Municipal Code.12 Start a proposed home with a parcel-specific Planning discussion, then ask Permit Processing for the building application requirements and fee estimate for that design.1211

Does Santa Maria have zoning, lot-size and height rules?

Santa Maria has its own zoning districts and a zoning map establishing district locations and boundaries.2 In Santa Maria’s R-1 Single-Family Residential District, interior lots generally require 6,000 square feet and corner lots 7,000 square feet; a subdivision map may allow smaller lots where overall density remains consistent with the General Plan.13 The R-1 maximum building height is 30 feet.14 In the RA Residential Agricultural District, dwelling and public-assembly structures are limited to 25 feet and two stories, while accessory buildings may reach 35 feet.15 Ask Planning for the parcel’s district and applicable setbacks before choosing a floor plan.12

How do septic permits work inside Santa Maria?

Every new or replacement septic system in Santa Barbara County requires a permit through the local jurisdiction or the Central Coast Water Board.4 Systems within County jurisdiction that do not meet the approved Local Agency Management Program or applicable Tier 1 conditions need Water Board permitting.5 We could not confirm the local septic-permitting arrangement inside Santa Maria; ask County Environmental Health and the Water Board which office administers the proposed city parcel.51617 A City building permit does not replace the separate septic approval for a new or replacement system.14

Can you live in an RV or tiny home in Santa Maria?

California generally limits RV occupancy to mobilehome or special occupancy parks unless a local ordinance allows otherwise, and RVs are not intended as permanent dwellings.6 We could not confirm a Santa Maria exception for residential RV use on a private lot; ask City Planning about the proposed location and duration before buying an RV as construction housing.12 California requires a tiny home to fit an approved classification, meet the applicable construction standards and occupy an approved location.7 Ask Santa Maria Planning which classification and land use the proposed tiny home would require on the parcel.127

Building a home in Santa Maria: what should you do first?

Start with Santa Maria Planning to establish the parcel’s zoning and whether the proposed home needs a discretionary planning approval.1211 Next, ask Permit Processing for application routing, plan-check requirements and a building-permit fee estimate.11 Resolve the wastewater permitting authority early if proposing a new or replacement septic system.4 If proposing a private well, obtain the City Director of Utilities’ determination before designing around well water, because Santa Maria generally prohibits well construction except under narrow conditions.9 Obtain the required building permit before beginning regulated construction.18

What should you check before buying land in Santa Maria?

A private domestic well is not a routine alternative to City water in Santa Maria: the Director of Utilities may permit domestic, commercial or industrial wells only for temporary use under specified conditions concerning nearby water mains and the feasibility of extending service.9 The owner or lessee must agree to destroy the well within 90 days after notice when adjacent water mains are installed.9 Ask Planning about subdivision review before assuming a parcel can be split; Santa Maria’s subdivision ordinance addresses tentative, final and parcel maps.1912 We could not confirm Santa Maria’s general occupancy-clearance or driveway-access requirements; ask the Building Division which approvals the proposed home needs before occupancy.11

Watch-outs

  • Santa Maria’s R-1 lot and height standards are district-specific; identify the parcel’s zoning before applying those dimensions.131412
  • Do not treat an owner-builder contractor-licensing exemption as permission to skip a Santa Maria building permit.81
  • We could not confirm private-lot RV occupancy, temporary camping or tiny-home siting rules in Santa Maria; ask City Planning for the proposed parcel’s requirements.12
