Built for Los Angeles Homes
We work across the City of Los Angeles, and the practical reality is that two addresses ten minutes apart can sit under completely different rule sets. One parcel is flat R1 with a straightforward pool permit; the next is inside a hillside area, a methane zone, an HPOZ, or a very high fire hazard severity zone.
Our first move on any Los Angeles project is pulling the parcel's zoning and hazard overlays before a single line gets drawn.
Lot character varies enormously, from 5,000-square-foot flat R1 parcels in the older grid neighborhoods to steep, irregular hillside lots where usable outdoor space has to be manufactured with retaining structures and cantilevered decking.
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 Los Angeles: LADBS issues residential building, grading, plumbing, electrical and pool permits citywide, with Development Services Centers downtown and in Van Nuys, West Los Angeles, South Los Angeles and San Pedro, while zoning entitlements and design review come from Los Angeles City Planning.
Parcels in a designated hillside area fall under the Baseline Hillside Ordinance (No. 184,802), which limits residential floor area, building envelope height, and grading and import/export quantities. Protected trees and shrubs (native oaks other than scrub oak, western sycamore, Southern California black walnut, California bay, Mexican elderberry and toyon) are regulated under LAMC 46.00 at four inches of cumulative trunk diameter, and removing or relocating one needs a StreetsLA Urban Forestry Division permit. Review length varies by parcel and scope.
Permit details checked September 2026 against LADBS . Rules change, so we confirm them again for your parcel.

Local Conditions
What to Know in Los Angeles
These local conditions change the scope, the schedule and the budget.
01
Soil swings from deep alluvial fill on the valley floors to weathered bedrock and old landslide debris in the hills, so the geotechnical report drives foundation and pool shell design more than the architecture does.
02
Older neighborhoods still carry 100-amp services, clay sewer laterals and galvanized supply lines that must be upgraded before a pool, spa heater and outdoor kitchen can be added.
03
Many pre-1940 parcels have a detached rear garage off an alley, and that alley is often the only viable equipment path, deciding whether excavation is machine work or conveyor and hand work.
04
Hillside streets are narrow and frequently lack turnarounds, so staging for concrete, gunite and crane picks has to be planned around fire access requirements and neighbors.

Investment
What It Costs in Los Angeles
Real Southern California price ranges, not teaser numbers.
Plans, drawings and permit management
$4,500 to $25,000+

Detached ADU
$150,000 to $400,000+
What moves it: square footage, finish level, utility runs, and site access; garage conversions typically run well below a ground-up detached build
Retaining walls
$60 to $150 per face foot
What moves it: height, whether the wall is engineered, material choice, drainage behind the wall, and access for equipment and materials
Your lot, access and finishes set the price. We walk the site, then show you where every dollar goes.

The Process
How We Work in Los Angeles
01
Feasibility
We check zoning, setbacks, easements and utilities to confirm what the property will actually support before you spend on drawings.
02
Survey & As-Builts
The site and existing structure are measured and drawn so the permit set starts from reality, not an old plot plan.
03
Design Development
Plans and elevations developed to the level of detail plan check expects, with 3D so you can see it clearly.
04
Consultants
Structural engineering, Title 24 and, where the site needs it, a soils report are coordinated into one set.
05
Submittal
We make the submittal and act as the applicant, so correspondence with the city comes to us rather than to you.
06
Corrections & Issue
We respond to plan-check corrections, resubmit, and see the permit through to issue.
Questions
What Los Angeles Homeowners Ask
Who issues the permits for this work in Los Angeles?
Los Angeles Department of Building and Safety (LADBS). LADBS issues residential building, grading, plumbing, electrical and pool permits citywide, with Development Services Centers downtown and in Van Nuys, West Los Angeles, South Los Angeles and San Pedro, while zoning entitlements and design review come from Los Angeles City Planning.
Parcels in a designated hillside area fall under the Baseline Hillside Ordinance (No. 184,802), which limits residential floor area, building envelope height, and grading and import/export quantities. Protected trees and shrubs (native oaks other than scrub oak, western sycamore, Southern California black walnut, California bay, Mexican elderberry and toyon) are regulated under LAMC 46.00 at four inches of cumulative trunk diameter, and removing or relocating one needs a StreetsLA Urban Forestry Division permit.
Review length varies by parcel and scope. 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 Los Angeles different?
Lot character varies enormously, from 5,000-square-foot flat R1 parcels in the older grid neighborhoods to steep, irregular hillside lots where usable outdoor space has to be manufactured with retaining structures and cantilevered decking. One local condition that shapes the work: Soil swings from deep alluvial fill on the valley floors to weathered bedrock and old landslide debris in the hills, so the geotechnical report drives foundation and pool shell design more than the architecture does.
Which parts of Los Angeles do you work in?
All of it, including Hancock Park, Los Feliz, Silver Lake and Cheviot Hills. Our crews run every job out of our Cahuenga Pass base in Los Angeles, with our own people on site.
What do plans and permits cost in Los Angeles?
Plans, drawings and permit management: generally $4,500 to $25,000+ across Southern California. What moves it is project type and size, whether structural engineering, Title 24 or a soils report is required, and how many jurisdictions or review bodies are involved.
We give line-item pricing after seeing the site rather than quoting a number over the phone.
Can you do the plans without doing the build?
Yes. Plans and permits is a service we sell on its own, and plenty of clients use us for the drawing set and permit management and build with someone else. We would rather do it properly than tie it to a construction contract.
Why do permit costs vary so much?
Because the required consultants vary. A straightforward patio cover needs a modest set. An ADU on a sloped lot may need structural engineering, Title 24, a soils report and a survey, and each of those is a separate specialist fee on top of the city's own plan-check and permit charges.
What causes plan-check corrections?
Most commonly incomplete structural detail, missing Title 24 forms, drainage not shown, or a discrepancy between the site plan and the survey. Corrections are normal, not a failure. The thing that costs time is a slow response to them, which is why we act as the applicant.
Do you handle HOA approval too?
Yes, where a community requires it. HOA architectural review runs on its own calendar and its own standards, entirely separately from the city, and starting it late is one of the most common reasons a project slips.
