# San Diego & Chula Vista BESO Compliance Guide: June 1 Filings & Audit Targets

**Short answer:** Commercial and multifamily landlords operating across San Diego County encounter two separate municipal ordinances running alongside [California statewide AB 802](https://bcesg.org/california-ab-802-building-energy-benchmarking-guide/): [San Diego Municipal Code Chapter 14, Article 14](https://www.sandiego.gov/planning/climate-action/benchmarking) (annual **June 1** benchmarking at **>=50,000 sq ft**) and [Chula Vista BESO (Municipal Code Ch. 15.26)](https://www.chulavistaca.gov/departments/clean/benchmarking), which sweeps smaller **>=20,000 sq ft** buildings into benchmarking plus periodic audit/efficiency upgrade duties.

Even inside the City of San Diego, matching AB 802's >=50,000 sq ft cutoff does not substitute for local compliance: property owners must share Portfolio Manager reporting templates directly with San Diego's City Planning Department every June 1, while South Bay landlords inside Chula Vista track sub-50k buildings excluded from AB 802 altogether.

### Statutory Status at a Glance
- **San Diego (Ch. 14, Art. 14 — >=50,000 sq ft):** Annual June 1 whole-building energy disclosure via Portfolio Manager for commercial and multifamily buildings; aligns date with CEC AB 802.
- **Chula Vista BESO (Ch. 15.26 — >=20,000 sq ft):** Lower floor pulls 20k–49,999 sq ft retail, office, and apartment properties into annual benchmarking plus phased audit/upgrade compliance.
- **SDG&E Automated Sync:** Setting up SDG&E aggregated electric and natural gas feeds once covers CEC AB 802, City of San Diego, and Chula Vista filings cleanly.

## Handling Jurisdictional Borders & Chula Vista Upgrade Duties

Regional asset managers with retail centers or industrial-flex parks spanning Mission Valley, Sorrento Mesa, and Eastlake/Chula Vista should verify municipal boundary lines on County parcel maps: Chula Vista's >=20,000 sq ft threshold captures dozens of medical offices and multifamily complexes invisible to statewide AB 802.

Where Chula Vista BESO identifies below-threshold performance during audit phases, owners should check whether recent HVAC, lighting, or high-performance ENERGY STAR scores qualify for compliance deferral or exemption prior to commissioning engineering studies.

- **Direct City Share Required:** Confirm separate Portfolio Manager sharing links for San Diego City Planning and Chula Vista Sustainability.
- **June 1 Combined Sprint:** Complete SDG&E data pulls in April to clear municipal and AB 802 filings on June 1 simultaneously.

## Frequently Asked Questions

### If my San Diego building >=50,000 sq ft already files California AB 802, do I still file locally?

Yes. San Diego Municipal Code Ch. 14, Art. 14 requires submitting a Portfolio Manager benchmarking report directly through the City of San Diego's municipal reporting template by June 1.

### How is Chula Vista BESO different from San Diego's benchmarking ordinance?

Chula Vista BESO (Ch. 15.26) covers smaller properties starting at >=20,000 sq ft rather than 50,000 sq ft, and adds phased energy audit or performance upgrade obligations beyond benchmarking.
