Permits & Zoning

LADBS Permitting Guidelines for the San Fernando Valley

What San Fernando Valley homeowners need to know before starting an ADU project.

LADBS Van Nuys Plan Review
Valley residential building plans go through the LADBS Van Nuys District Office. We prepare complete structural calculations and Title 24 energy documents to secure fast plan check approvals.
Setback and Height Standards
Detached accessory units require 4-foot rear and side setbacks under California state standards. Additionally, standalone structures can reach up to 16 to 18 feet in height.
Electrical Service Upgrades
Older Valley ranch homes often feature 100-amp main service panels. Therefore, we evaluate your existing electrical capacity during our initial site audit to determine necessary 200-amp panel upgrades.
Dual Unit Opportunities
Most single-family parcels qualify for both a detached ADU and an interior Junior ADU. Consequently, homeowners can create two distinct rental units on a single parcel.

Common Questions

ADU Questions for San Fernando Valley Homeowners

How much does a San Fernando Valley ADU builder charge?
Garage conversions typically start at $95,000. Meanwhile, detached two-bedroom guest homes range between $195,000 and $295,000. We provide fixed-price contracts after completing a detailed site feasibility audit.
What is the maximum ADU size allowed in the San Fernando Valley?
LADBS permits detached secondary homes up to 1,200 square feet on single-family lots. In addition, Junior ADUs can measure up to 500 square feet within the primary residence.
How long does LADBS take to approve Valley ADU permits?
Standard plan review through the Van Nuys district office takes between 8 and 16 weeks. Furthermore, our expediting team tracks each submittal milestone to eliminate permit processing delays.
Do I need to upgrade my electrical panel for a Valley ADU?
Many older Valley residences carry 100-amp electrical panels. Because modern secondary homes require mini-split cooling and all-electric appliances, we frequently upgrade panels to 200 amps.
Can I build a two-story ADU in the San Fernando Valley?
Yes, California law allows two-story accessory units up to 18 feet in height near transit stops. However, we verify local height restrictions and privacy setbacks during your initial lot review.
Which Valley neighborhoods do your construction crews serve?
Our crews build across Sherman Oaks, Encino, Woodland Hills, Studio City, Northridge, and Tarzana. Therefore, we understand specific soil conditions and municipal requirements across the entire Valley.
Does building an ADU require adding off-street parking?
No, California state law exempts properties within one-half mile of public transit from parking requirements. Consequently, you can convert your garage without constructing replacement parking spaces.
How much monthly rental income can a Valley ADU generate?
Studio units typically rent for $2,000 to $2,400 monthly. Moreover, two-bedroom detached guest houses in neighborhoods like Encino frequently command $3,200 to $3,800 per month.
