Permit counts, by the date issued (or applied, if not yet issued). Lot splits are planning cases, which we don't have.
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 Richmond's planning department before relying on it.

California AB 1482 (Tenant Protection Act, Civ. Code § 1947.12) caps annual rent increases at 5% + local CPI (max 10%) on covered properties. In Richmond: Richmond Fair Rent, Just Cause for Eviction, and Homeowner Protection Ordinance — annual cap of 60% of CPI or 3.0% (whichever is lower) for covered pre-1995 units.
