We don't have building permits for Piedmont, so we can't show what has been permitted nearby.

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 Piedmont's planning department before relying on it.

Rental regulatory context (informational only — not legal advice):

California AB 1482 (Tenant Protection Act, Civ. Code § 1947.12) caps annual rent increases at 5% + local CPI (max 10%) on covered properties.

Common statutory exemption signals under AB 1482

Housing issued a certificate of occupancy within the last 15 years (rolling exemption under AB 1482).
Separately alienable single-family homes or condominiums not owned by a corporation, REIT, or LLC with a corporate member (when required statutory notice is in the lease).
Owner-occupied duplexes where the owner occupied one unit from the start of the tenancy.
