HOA vs City Codes? Who rules?

[Gary F.]

In San Jose and per codes I’m allowed to build an accessory Dwelling unit in my backyard. But our local neighborhood HOA CCR might prevent it. This is a single family residence not condo. 4. Use of Lots. The Lots shall be occupied and used as follows: (a) No Lot (as "Lot" is defined in paragraph 1 (b) above) shall be used except for single family residential purposes. No dwelling designed for occupancy by a single family shall be occupied by more than one family, nor shall any such dwelling exceed two and one-half (2-1/2) stories in height. No structure of a temporary character, trailer, tent, garage, or outbuilding shall be used on any Lot at any time as a residence either temporarily or permanently. What’s your understanding of this bylaw as it reads?
