Frequently Asked Questions (FAQ)

I am looking for the standards on a full set of construction documents. I also need updated information for building codes for those projects (residential) to be built in the flight zone of LAX. I am looking at adding 1200 to 1800 s.f. to my existing home and remodeling the interior of the existing. I plan on undertaking this project as owner operator.

Thank you for contacting the County of Los Angeles Department of Public Works. There are a number of requirements, mostly related to sound insulation and construction design techniques that must be incorporated into residential design in the flight zone area you have described. You will need to contact the Building and Safety Division's Firestone District Field Office at the address shown below to obtain the details for construction.

With respect to the design, a homeowner may design his or her own home, under the condition that it is of conventional construction. A plan check engineer at the Firestone office can explain to you the details of conventional construction. However, if the addition/remodel is considered to be non-conventional, you may be required to hire a licensed architect or engineer to work with you on the design and calculations. Please feel free to address further detailed questions to our professional building plan check engineers at out Firestone district office. Thank you.
