Half the county is unincorporated
The California Department of Finance counts 261,069 people in Santa Cruz County, and 126,303 of them (48%) live in unincorporated areas, which hold 58,038 of the county's 108,787 housing units (53%) (January 1, 2026).
Units in 5+ unit buildings (DOF): Santa Cruz 5,732 · Watsonville 3,046 · Capitola 1,148 · Scotts Valley 413 · unincorporated 3,835 (county total 14,174).
So unincorporated communities such as Aptos and Soquel get their permits from the County, not a city, and the County's process matters as much as any city's.

Re-roof permits, county and city by city: what we've confirmed
The same commercial re-roof can be an online application in one city and a plan-reviewed submittal in the unincorporated county.
| Where | What we've confirmed | Source |
|---|---|---|
| Unincorporated county | A building permit is required to re-roof all structures, except maintenance, sealing leaks or structures under 120 square feet. Coverings must be Class B or better. Inspections: pre-roof/tear-off, sheathing and final; an optional re-roof certificate can replace the tear-off and sheathing inspections. Safe access per OSHA is required. Commercial and industrial re-roofs aren't eligible for the online EZ permit; they go to electronic plan review (ePlan), and plan review is charged as a percentage of the permit fee | Santa Cruz County CDI, Re-roofing Permit & Inspection Procedures; EZ Permits page |
| Unincorporated, wildland-urban interface (WUI) areas | A Class A roof is required. Re-roofing 50% or more within 12 months must meet new-construction roof rules, repair coverings must be at least Class A, and coatings and paints aren't approved protection methods | County WUI page (CWUIC 504.2, 507.1, 503.2.5) |
| Unincorporated, Coastal Zone | Coastal Zone review can override the normal permit exemptions; ask the County whether your project needs it | County, “When is a permit not required” |
| City of Santa Cruz | A building permit is required; applications, fees and tracking go through the city's Access Santa Cruz online system. A job-site card and a ladder must be on site for inspections, and the city's inspection types include a commercial roof final | City of Santa Cruz Building & Safety |
| Watsonville | City code requires Class B minimum roof assemblies, and where more than 50% of the roof is replaced within one year, the entire covering must be at least Class B | Watsonville Municipal Code §8-2.03 (amending CBC 1505.1) |
| Scotts Valley | Online permit portal. The application asks for written HOA board approval on HOA sites; rooftop HVAC changes need a roof plan with screening; permits expire after 180 days without an inspection | City of Scotts Valley Building |
| Capitola | A permit is required to re-roof all structures, except maintenance, sealing leaks or structures under 120 square feet; Class B or better. Inspections: pre-roof/tear-off, sheathing (or a re-roof certificate from a C-39 contractor in place of both), in-progress at 25–75%, and final. Existing solar PV needs qualified removal and reinstallation, with a Solar R&R Affidavit before issuance. Apply through the city's online portal | City of Capitola, “Reroof and Reroof with Solar (PV) Requirements” |
Permit applicability is reviewed for your specific project during scoping rather than assumed.
The wettest roofs in our service area
NOAA's 1991–2020 normals (NCEI):
- Santa Cruz: 30.63 inches of rain a year, January wettest (6.42 inches), about 85% falling November through March. Average highs peak in September (76.7°F).
- Watsonville (Water Works station): 22.67 inches a year, December wettest (4.51 inches), also about 85% November through March.
San Jose's airport station averages 13.48 inches (NCEI), so Santa Cruz gets about 2.3 times as much (30.63 ÷ 13.48).
Drains, scuppers and flashings carry more water here, roofs stay damp longer, and coastal salt air is hard on exposed metal. See flashing, sheet metal and drainage.
Title 24 here
The CEC's ZIP list puts every county ZIP we checked (95003, 95005, 95006, 95010, 95018, 95060, 95062, 95065, 95066, 95073 and 95076) in climate zone 3. Confirm the zone for your address. On nonresidential low-slope roofs, California's Energy Code applies cool-roof requirements when the area replaced, recovered or recoated is more than 50% of the roof or more than 2,000 square feet, whichever is less (Energy Code §141.0(b)2B). The new surface must be a CRRC-rated product that meets the code's reflectance and emittance minimums, and a re-roof over conditioned space in Bay Area climate zones 3, 4 and 12 generally also needs R-23 continuous insulation (BayREN, Table 141.0-C). Recoats are exempt from the insulation rule. Our Title 24 re-roof guide walks through the trigger, the cool roof values and the insulation rule.

Frequently Asked Questions
Yes. Commercial Roofing Inc. repairs, inspects, coats and replaces commercial, multifamily and HOA roofs in Santa Cruz, Watsonville, Scotts Valley, Capitola, Aptos and Soquel. Each permit office has its own rules, so permit requirements are reviewed for each project. Call (408) 770-5992 or request a bid.
Yes, for nearly every structure. The County requires a building permit to re-roof, except for maintenance, sealing leaks or structures under 120 square feet. Coverings must be at least Class B, and Class A in wildland-urban interface areas. Commercial and industrial re-roofs go through the County's electronic plan review instead of the online EZ permit.
A coating can't be what makes the roof compliant. The California Wildland-Urban Interface Code, applied by Santa Cruz County in WUI areas, requires a Class A roof and says coatings and paints aren't approved protection methods. Re-roofing half or more of a roof within 12 months triggers new-construction roof rules.
About 30.6 inches a year at the Santa Cruz station, per NOAA's 1991–2020 normals, with January the wettest month at 6.42 inches. That's more than twice San Jose's 13.5 inches. Watsonville averages about 22.7. Around 85% falls November through March, so fall drain and flashing checks matter here.
The California Energy Commission's ZIP list puts the Santa Cruz County ZIPs we checked in climate zone 3. Qualifying nonresidential low-slope re-roofs there need a CRRC-rated cool roof and, over conditioned space, generally R-23 continuous insulation. Confirm the zone for your address with the CEC.
