San Jose FAQ
Do I need a permit for a 20-foot inflatable Santa?
No city permit is needed on private property. SJMC 20.120 exempts residential holiday displays from the sign code and the city has no size cap. Your HOA, if any, will likely cap height at 8-12 feet and may prohibit it altogether.
My neighbor's inflatable runs all night - is that a violation?
The display itself is fine, but the blower motor must comply with the noise ordinance (SJMC 6.20). If a measured reading exceeds 55 dBA at your property line between 10 p.m. and 7 a.m., it can be cited as a noise violation.
Sunnyvale FAQ
Can I put a giant inflatable Santa in my Sunnyvale yard?
Yes - Sunnyvale has no city ordinance limiting inflatable holiday decorations on private property. Your condo or townhome HOA may impose height, timing, and removal rules under the Davis-Stirling Act. Inflatables placed in the public right-of-way (sidewalk) are prohibited under SMC Title 12.
Can my Sunnyvale HOA ban inflatable decorations?
Yes. California Civil Code 4710 protects 'noncommercial signs, posters, flags, or banners' but specifically excludes inflatable objects, so HOA architectural rules can restrict or ban them. Fines for violations are capped at $100 per occurrence under California Civil Code 5850.
