Wildfire defensible space in East Bay hills: inspections, tree rules, programs

By Michael Schuck, ISA Certified Arborist WE-15750A · Updated 2026-10-20

The 1991 Oakland Hills fire is why the East Bay has the Bay Area's most developed inspection programs: Oakland inspects roughly 26,000 hills parcels every year, Berkeley requires annual inspections in its Grizzly Peak and Panoramic areas and adopted Zone 0 into its code in 2025, and Moraga-Orinda Fire has an ordinance with specific species rules. It also has the Bay Area's strictest oak protection — Oakland at 4 inches — so 'the inspector said remove it' and 'the city says you can't' happen on the same lot every week.

Who inspects, and against what

Oakland Fire Vegetation Management Unit: 2026 season began in June; 45-day correction window; re-inspection fees; lien as last resort; 510-238-7388, wildfireprevention@oaklandca.gov. Berkeley Fire WUI Division: appointment-based annual inspections in the mitigation areas and Very High zone, Zone 0 inspections since May 2026; 510-981-5620, wildfire@berkeleyca.gov. Moraga-Orinda Fire District: Ordinances 23-03 and 23-08. Contra Costa County Fire (Lafayette, unincorporated): 925-941-3300. Alameda County Fire (Castro Valley, Fairview): 510-632-3473 x1190.

Standards are the state's (PRC §4291 / Gov Code §51182) plus local ordinance. Zone 0 is not yet an enforceable state rule (status), but several agencies here already inspect to it.

Tree ordinances vs. fire removal here

Orinda is the clean case: removal required by Moraga-Orinda Fire for Fire Code compliance is exempt from the permit — document it to Planning. Lafayette waives the fee for ConFire-noticed trees and exempts trunks within 5 feet of a building, but the permit stays. Moraga exempts trees within 5 feet of a structure and has no fire clause. Oakland and Berkeley have no fire exemption at all; in Oakland, 'hazard to life or property' and vegetation management are grounds for approval, and eucalyptus and Monterey pine are unprotected. Berkeley protects only coast live oak (18 inches circumference), and its EMBER ordinance lets mature trees stay in Zone 0.

What we see most on site visits

Blue gum eucalyptus groves and Monterey pine along the ridge from Claremont to Skyline — unprotected in Oakland, but the scale makes it a scope-and-phase problem.
Coast live oaks and bays grown into roofs in Montclair, Piedmont Pines, Berkeley's Panoramic Hill, and the Orinda and Lafayette canyons — pruning with a documented clearance standard, thinning only with a report.
Juniper, acacia, and bamboo on the flat lots of Rockridge, Upper Rockridge, and north Berkeley — removal, no permit under the size thresholds (Oakland protects any species at 9 inches).
Annual grass and broom on the open slopes of Moraga and Lafayette — MOFD's 3-inch-by-June-1 rule.

Is the site visit free?

No — your fire agency's inspection is free and tells you what fails. The $375 consultation or $850 written plan is the certified-arborist judgment on the trees, the permit flags, and documentation built to what an insurer or city asks for.
