We read public zoning and hazard maps against state law (ADUs: Gov. Code 66314; SB 9: Gov. Code 65852.21 and 66411.7). Local rules, title, tenancy history and site conditions can change the answer. Check with Unincorporated Marin's planning department before relying on it.

ZIP & neighborhood mediansUnder California Proposition 13, the seller's historical assessed value does not carry over to a buyer. On sale, the parcel is reassessed at the purchase price: 1.00% base rate ($8,735/yr) + local voter-approved bond debt ($1,310/yr) + fixed direct levies/Mello-Roos ($450/yr).
Mapped hazard zone insurance context on this parcel:
Model adding a backyard ADU or garage conversion under California's Prop 13 blended new-construction assessment (existing house & land tax base stays intact; only ADU build cost is assessed) and SB 13 impact-fee rules.
Statutory notes: Under CA Gov. Code § 66324 (SB 13), local agencies cannot impose development impact fees on ADUs under 750 sq ft (plan-check, school district fees ≥500 sq ft, and utility connection fees still apply). Under CA Rev. & Tax. Code § 71, building an ADU triggers a supplemental assessment on the new construction value without reassessing the existing dwelling or land. Newly built ADUs also carry a rolling 15-year exemption from statewide AB 1482 rent caps from certificate of occupancy.
