Santee bundles ADUs, JADUs, SB 9 splits, density bonus, and Essential Housing into one Housing Streamlining hub. The city's ADU fee waiver program ended in 2024 — full fees now apply.
Detailed standards in Santee Municipal Code §13.10.045. The city ADU/JADU guide covers practical numbers.
State guarantee: California requires every city to allow at least an 800 sq ft ADU exempt from local lot coverage, FAR, and front-setback rules.
Height baseline: 16 ft for detached, rising to 18 ft within ½ mile of major transit. Attached ADUs follow the primary home, capped at 25 ft.
See the SMC and ADU/JADU guide. Larger ADUs may require on-site parking unless a transit or state exemption applies.
Streamlined Housing Application Guide (2025 portal PDF). SB 330 preliminary applications accepted. Permit Ready ADU Plans (PRADU) program also available.
State backstop: A complete ADU permit must receive a decision in 60 business days. If the city stalls past 30 business days, AB 253 lets you hire a certified private plan checker to force a 10-business-day decision.
The ADU Fee Waiver Program ended September 27, 2024. Full fees now apply at issuance unless other state programs cover the project.
SB 543: No impact fees on ADUs ≤750 sq ft. Above 750 sq ft, fees scale to the ratio of ADU size vs the main home.

Standard ADUs in Santee: no owner-occupancy required (made permanent in 2023).
JADUs: limited to 500 sq ft of interior livable space within an existing single-family home. Owner occupancy is required only when sanitation facilities are shared with the main house. JADUs cannot be used as short-term rentals (AB 1154 / SB 543).
Sketch a floorplan, walk through it in 3D, and have our planners review it for size, height, and setback compliance before you submit to Santee.
Heads up: Local rules change frequently. This page summarizes publicly available state law (California Government Code §§ 66310–66342) and current local guidance for general planning purposes.
