Built for North Hollywood Homes
Most of what we build in North Hollywood happens on tight 1920s-to-1950s lots where the house sits close to the street and the whole project lives in the back forty feet. Access is the constant: narrow side yards, alley approaches, and neighbors on both sides.
We size equipment to the gate we actually have, and we look hard at the existing panel and sewer before committing to an ADU or a pool.
Most parcels are compact rectangles with the house pushed toward the street and narrow side yards, leaving a modest but workable rear yard. Detached rear garages are common and are frequent conversion candidates.
We are a design-build team, which means the people who draw your project are the people who build it. Design, engineering, permits and construction run through one project manager and our own crews, so nothing gets lost in a handoff between a salesperson and a subcontractor. We are licensed, bonded and insured, CSLB license #1119054 .
Permits in North Hollywood: LADBS is the permitting authority, and Valley projects are plan-checked and inspected through the Van Nuys Development Services Center. No coastal or hillside overlay applies on this section of the valley floor. Where a parcel falls in a CGS-mapped liquefaction zone (ZIMAS shows it), LADBS Information Bulletin P/BC 2026-044 still exempts one- and two-family dwellings, ADUs under three stories, and pools, spas and decks from the liquefaction-zone investigation, so soils report needs are settled with plan check.
The city's protected tree and shrub ordinance covers oak, western sycamore, black walnut, California bay, Mexican elderberry and toyon at four cumulative inches of trunk diameter, and removal or encroachment needs an Urban Forestry permit. Pool barrier height, self-closing and self-latching gates and drowning-prevention features are verified at final inspection, and review durations vary.
Permit details checked September 2026 against LADBS , LA City Planning and California law . Rules change, so we confirm them again for your parcel.

Local Conditions
What to Know in North Hollywood
These local conditions change the scope, the schedule and the budget.
01
Narrow side yards decide whether an excavator reaches the rear or the dig becomes a conveyor-and-hand-load operation.
02
Alley access behind many blocks is the practical staging route for gunite, concrete and material deliveries, and overhead utility clearance has to be checked before scheduling.
03
Housing from the 1920s through the 1950s often has raised perimeter foundations with under-reinforced stem walls that need attention before a large addition ties in.
04
Mature street trees and dense rear-yard canopy limit crane picks and shade pool areas enough to change heater sizing and planting selection.

Questions
What North Hollywood Homeowners Ask
Who issues the permits for this work in North Hollywood?
Los Angeles Department of Building and Safety (LADBS). LADBS is the permitting authority, and Valley projects are plan-checked and inspected through the Van Nuys Development Services Center. No coastal or hillside overlay applies on this section of the valley floor.
Where a parcel falls in a CGS-mapped liquefaction zone (ZIMAS shows it), LADBS Information Bulletin P/BC 2026-044 still exempts one- and two-family dwellings, ADUs under three stories, and pools, spas and decks from the liquefaction-zone investigation, so soils report needs are settled with plan check.
The city's protected tree and shrub ordinance covers oak, western sycamore, black walnut, California bay, Mexican elderberry and toyon at four cumulative inches of trunk diameter, and removal or encroachment needs an Urban Forestry permit. Pool barrier height, self-closing and self-latching gates and drowning-prevention features are verified at final inspection, and review durations vary.
We prepare the drawings, make the submittal and handle plan-check corrections ourselves, so you are not the one chasing plan check.
What makes building in North Hollywood different?
Most parcels are compact rectangles with the house pushed toward the street and narrow side yards, leaving a modest but workable rear yard. Detached rear garages are common and are frequent conversion candidates. One local condition that shapes the work: Narrow side yards decide whether an excavator reaches the rear or the dig becomes a conveyor-and-hand-load operation.
Which parts of North Hollywood do you work in?
All of it, including NoHo Arts District, North Hollywood West and Toluca Woods. Our crews run every job out of our Cahuenga Pass base in Los Angeles, with our own people on site.
What does an ADU or addition cost in North Hollywood?
Detached ADU: generally $150,000 to $400,000+ across Southern California. What moves it is square footage, finish level, utility runs, and site access; garage conversions typically run well below a ground-up detached build. We give line-item pricing after seeing the site rather than quoting a number over the phone.
How long does an ADU take start to finish?
Plan a realistic year. Design and engineering typically take one to three months, city plan check and corrections add several more, and construction usually runs four to eight months depending on size and site access.
Is a garage conversion cheaper than a detached ADU?
Usually yes, and often substantially, because the foundation, walls and roof already exist. The trade-offs are that you lose the garage, and older slabs and framing sometimes need upgrading to meet current code.
Can I rent the ADU out?
California ADU law is designed to allow long-term rental, and an ADU is one of the few ways to add rentable square footage to a single-family lot. Short-term rental rules vary by city, so confirm your local ordinance before counting on that income.
Do you handle the permits?
Yes. Plans, engineering, Title 24 and the city submittal are all handled in-house, including responding to plan-check corrections. That is a service we sell on its own, so it is not something we hand off.
