California Permit & Code Enforcement Laws: 2026
On This Page
2026 Legislative and Regulatory Changes
California's building code and permit enforcement landscape continues to evolve. This page summarizes key changes relevant to property owners in 2026.
ADU Permitting Streamlining
California has continued to streamline ADU permitting, reducing barriers to legalizing existing structures. Many previously unpermitted garage conversions and secondary units may now be easier to legalize.
SB 37 — Attorney Advertising Transparency
Effective January 1, 2026, SB 37 requires attorney websites to include the responsible attorney's name, bar number, and bona fide office location. This site complies with SB 37.
Code Enforcement Trends
California cities continue to expand enforcement using satellite imagery, permit database cross-referencing, and complaint hotlines. Property owners should assume unpermitted work will eventually be discovered.
Impact on Property Owners
Increased enforcement and easier ADU permitting mean both more incentive and more opportunity to resolve permit issues proactively.

What changed in California permit law for 2026?
Key changes include continued ADU streamlining, SB 37 attorney advertising requirements, expanded code enforcement technology, and increased local enforcement budgets.
Are there any new amnesty programs for unpermitted work in 2026?
Some jurisdictions periodically offer amnesty or legalization programs. Check with your local building department for current programs. State-level ADU reforms have made legalization easier in many areas.
Does SB 37 affect permit violation attorneys?
SB 37 requires attorney advertising transparency (name, bar number, office location) but does not change the substance of permit violation law or property owner rights.
