According to the City of Downey's website, "Generally, any new construction, additions, alterations or repairs to an existing building, including re-roofs, fireplaces, swimming pools, carports, remodels, hardscapes, etc., requires a permit". I would advise checking with the city to be sure - you can reach them at 562-904-7143.
Here is a link to their website: http://www.downeyca.org/gov/cd/building/permits.asp
Hope this helps - good luck!

Every city works different but in some cases the same. If the eclosed den was done without permit and you want to include it in the event you want to sell the property then you will need to go to the city for it and to the county to give it it's proper assessment. Be aware that some cities may have penalties for having the work done without permit. Thay may ask you to demolish the work.
Even if you do some electrical work is minor and the City will not force you to bring everything up to new codes.
You will require permits for any electrical additions, most of the time a den has adequate electrical.
If you do not do any structure work and the house was built prior to smoke detectors being required you DO NOT need to install a new system. I would at least install battery type alarms.
For a habitable sleeping space there must be a window for light and ventilation and emergency exit, about 8% is good. if the room is 12 x 12 = 144 sf then the window must be at least 3 x 4 at around 36 inches from the floor.
If you want to sell the house advertising an additional bedroom then obtain a permit at that time.
How will this sleeping room be heated? Is the room more than 75 square feet. Are there receptacles at every wall that exceeds 2-feet in width? Must have a hard-wire smoke alarm with a battery back-up (inside and outside the room). All electrical outlets must be protected by an AFCI (Arc Fault) circuit. Must have dual pane window(s) that meet the minimum requirements for egress, ventilation and light. Don't forget sheer panels and R-30 insulation.
