What sits on top of the ranges in Santa Barbara and Montecito

City or County? Know which one you are building in

The City of Santa Barbara issues its own permits through its building permit page. Montecito, Hope Ranch and the unincorporated foothills are Santa Barbara County land, handled by Santa Barbara County Planning & Development. The rules, boards and utility providers differ, and so do the costs.

1. City of Santa Barbara: Single Family Design Board

Under the city’s Design Review Checklist, single-unit projects go to the Single Family Design Board when, for example, the work is over one story or 17 feet tall, total floor area passes 4,000 square feet, or grading outside the footprint passes 250 cubic yards. Historic properties can go to the Historic Landmarks Commission instead. Board review means more design rounds, renderings, material boards and months of holding costs.

2. Montecito: architectural review before any permit

In the Montecito Planning Area, the County will not issue zoning clearances, land use permits or coastal permits until the Montecito Board of Architectural Review grants final approval. The board reviews projects against the Montecito Architectural Guidelines, so plan for several design rounds.

3. Montecito floor-area guidelines shape the house

The County’s Montecito Floor Area Calculator sets a recommended maximum house size by lot area. For lots under one acre it is 1,800 square feet plus 2,500 times the lot area in acres, so a half-acre lot works out to about 3,050 square feet of house net floor area. Lots in the Montecito Hillside (H-MON) overlay use a lower formula (1,400 plus 2,100 times the lot area). Basements entirely below grade are excluded, which is one reason many Montecito homes dig down, adding excavation, shoring and waterproofing to the budget.

4. Water meters in Montecito

The Montecito Water District fee schedule, effective July 1, 2026, lists a new 3/4-inch meter at $35,453 (an $11,645 connection fee plus a $23,808 capital cost fee) and a 1-inch meter at $52,640, paid before the District installs the meter.

5. High fire hazard areas

Large parts of the Santa Barbara foothills and the Riviera are mapped by the city as high fire hazard areas, with defensible-space distances that vary by zone; the fire department runs a defensible space program. Montecito foothill lots can sit in mapped fire hazard severity zones too; check the CAL FIRE Fire Hazard Severity Zone maps. New work there is built to the wildfire chapter of the building code.

6. Hillsides, access and the coast

Riviera and foothill lots bring steep driveways, soils reports, engineered foundations and retaining walls, and narrow streets that limit truck size. Parcels near the waterfront and bluffs can be in the coastal zone, which adds a coastal development permit under the local coastal program overseen by the California Coastal Commission.

What else belongs in a Santa Barbara or Montecito budget

• Design and engineering: architect, structural engineer, energy compliance, survey, soils and geology reports.
• Permit, plan-check and board fees, plus school and impact fees.
• Demolition of an existing house, if there is one.
• Fire sprinklers, required in new California homes.
• Landscape and hardscape: design boards review landscape plans too. Our sister company, Paso Robles Landscaping, does landscaping in-house.
• Contingency and carrying costs while review and construction run.

How long it takes

Design review usually sets the pace here, so we build the board steps into your schedule from the start. Construction on our recent Central Coast homes took 9 to 14 months. See the build timeline guide.

How we put a real number on it

1. Free site walk: city or County, board triggers, floor-area limits, slope, access, water and fire zone.
2. Concept budget once there’s an early design, with review and utility items called out.
3. Written estimate from the plans, line by line, with allowances for selections still open.
4. Read more about how a job runs.
