Site Assessment in Los Angeles, CA
A site assessment for an ADU in Los Angeles typically costs $450 to $1,800 depending on lot complexity, and the full report usually takes 5 to 10 business days to complete. Most LA homeowners get a clear yes-or-no answer on whether their property can support an accessory dwelling unit, plus a written breakdown of what it will take to move forward. That’s exactly what we provide at Lodgewick ADU Los Angeles, and you can call us at (213) 698-7116 to schedule yours.
Before any ADU, garage conversion, or home addition gets designed or permitted, someone has to look at the actual ground you’re building on. A site assessment is that first honest look. It tells you whether your lot can hold an ADU under Los Angeles zoning code, where it can sit, how utilities will reach it, and what constraints will shape the design. Skip this step and you risk designing a unit that can never be permitted, or burying expensive surprises in a foundation trench. Our team handles site assessments as part of the broader ADU Design & Permitting in Los Angeles process, and we do it with written findings you can take to any designer, lender, or planning counter. Russ Delmar leads every assessment personally, which means you get answers from someone who has walked hundreds of LA lots, not a checklist from a call center.
The name Lodgewick fits what we do. A lodge is a small house on a larger property. That is precisely what an ADU is, and it’s why we focus on nothing else. Homeowners in Los Angeles call us when they want to know if their backyard can become a rental unit, a place for aging parents, or a home office with a door that closes. We tell them the truth, in writing, before any design fees are spent.

When You Need Site Assessment
Not every ADU project starts with a site assessment, but most should. Here are the situations where Los Angeles homeowners consistently need one before they do anything else:
- You have a sloped lot. Much of Los Angeles sits on hillsides, terraces, or lots with a surprising amount of grade change. A slope over 10% changes foundation type, drainage requirements, and sometimes whether an ADU can be placed at all. If your yard doesn’t sit flat, get a site assessment before you fall in love with a floor plan.
- Your property predates modern utility mapping. Homes built before the 1980s often have sewer laterals, gas lines, or water service that isn’t where current records say it is. We regularly find cast-iron sewer lines running right through the only logical ADU footprint in neighborhoods like West Adams and Highland Park.
- You’re considering a prefab ADU. Companies like Abodu, Cover, and Dvele build excellent units, but their delivery and placement depend on crane access, setback clearance, and foundation pad tolerances. A site assessment confirms whether your specific lot can accept a prefab unit before you put down a deposit.
- You have protected trees or a hillside ordinance in play. Los Angeles has specific oak tree protections and Hillside Construction Regulation zones. If your lot is in one of these zones, tree root zones and slope stability will dictate what you can build and where.
- You’re not sure if your garage can become an ADU. A garage conversion is the most popular ADU path in Los Angeles. A site assessment tells you whether the existing slab, framing, and roof are worth reusing, or whether you’d be better off with a foundation-to-roof new build in the same footprint.
- Your lender or designer asked for due diligence. Some lenders require a parcel feasibility report before approving ADU construction financing. We provide a clear, lender-ready document with parcel specifics, zoning findings, and utility notes.
If any of these sound like your lot, call (213) 698-7116. We’ll tell you over the phone whether a full site assessment is warranted, and we won’t charge you for that conversation.
Our Site Assessment Process
Here is how a site assessment with Lodgewick ADU Los Angeles works, step by step. Everything gets documented in writing, and you get a copy of every finding.
- Initial parcel review. Before anyone sets foot on your lot, we pull zoning records, parcel maps, utility easements, and any existing permit history for your address. This desk review happens within 3 business days of your signed estimate and catches most disqualifying issues before we spend your money on fieldwork.
- On-site walkthrough with Russ Delmar. Russ walks the entire lot with you or your property manager. He measures setbacks, identifies the utility connection points, checks access paths for construction equipment, and photographs everything that will matter during design. This typically takes 90 minutes on a standard lot, longer on hillside or canyon properties.
- Utility and drainage verification. We locate the sewer lateral, water service, gas line, and overhead or underground electrical service. For older LA homes, we may recommend a sewer camera inspection to confirm lateral condition and depth. Drainage is mapped so the design can keep rainwater flowing away from foundations.
- Zoning and code analysis. We run your parcel against current Los Angeles ADU ordinance requirements, including setback minimums, height limits, lot coverage, and parking rules. This includes checking for any overlay districts, coastal zone boundaries, or historic preservation requirements that affect your address.
- Written feasibility report. Within 5 to 10 business days of the site walk, you receive a written report. It includes a buildable area map, utility connection plan, a list of constraints, recommended ADU types for your lot, and a preliminary cost range. This document is yours to keep and use with any designer or contractor.
- Design and permitting handoff. If you decide to move forward with Lodgewick, the site assessment findings flow directly into our ADU Design & Permitting in Los Angeles team. Nothing gets re-measured, nothing gets re-litigated, and nothing gets lost between departments. If you take the report elsewhere, it still holds up.
Every step follows The Kingswell Way: the price is written before work begins, we show up in the window we give you, we leave your property cleaner than we found it, and every commitment is in writing. That is not a slogan. It is a guarantee, and it is named on every contract we sign.

Site Assessment Pricing in Los Angeles
Site assessment pricing in Los Angeles typically runs $450 to $1,800. The range exists because no two LA lots are alike, and we would rather quote you accurately than give you a fuzzy bundle price that changes later. Here is a straightforward breakdown of what you can expect:
| Assessment Component | Typical Cost Range |
|---|---|
| Desk review (zoning, parcel, permit history) | $150 – $350 |
| On-site walkthrough and measurements | $200 – $500 |
| Utility verification (sewer lateral, water, gas, electric) | $100 – $400 |
| Full written feasibility report | $250 – $550 |
| Hillside or complex-lot surcharge | $150 – $400 |
What moves the price within that range? A flat city lot in the San Fernando Valley with recent utility records is fast and straightforward. A canyon or hillside lot with protected trees, questionable utility mapping, and difficult access takes more time and more analysis. A property with existing as-built drawings, recent surveys, or a previous site assessment can sometimes skip desk-review work entirely.
Here is the part that matters to Los Angeles homeowners who have been burned before: the price we quote is the price you pay. Before we start any assessment work, you get a written estimate. No price changes at the door. No surprise line items after the report is delivered. That is The Kingswell Guarantee, and it applies to site assessments the same as it applies to a full ADU build.
The initial parcel review is available as part of every signed site assessment contract, and our phone consultation before that is always free. Call (213) 698-7116 and ask for a site assessment estimate. You’ll get a real number, not a callback.
Why Los Angeles Lots Are Different
Site assessment is not the same in every city. Los Angeles has a specific combination of geography, regulation, and housing stock that shapes what we look for on every lot.
First, the hills. Large portions of Los Angeles sit in Hillside Construction Regulation zones, which impose stricter grading rules, foundation requirements, and drainage standards than flat-lot builds. A lot that looks buildable in a listing photo may require retaining walls, deeper footings, or a completely different foundation system once soil conditions and slope stability are measured. We see this regularly in neighborhoods like Mount Washington, Echo Park’s northern slopes, and the canyons off Mulholland.
Second, the age and condition of existing utility infrastructure. Many LA homes built between 1920 and 1970 have sewer laterals made of clay or cast iron, some of which are original. When an ADU adds a second kitchen and bathroom to the parcel, the lateral must be sized correctly, and the city may require a cleanout or a full lateral replacement. A site assessment identifies this before the design phase, which saves homeowners from a nasty surprise during trenching.
Third, Los Angeles lot shapes and sizes vary wildly. A standard 50×120 lot in Mid-City behaves very differently from a flag lot in Silver Lake or a pie-shaped lot in Leimert Park. Setbacks, buildable area, and access for construction equipment all depend on the shape of the parcel and the placement of the existing home. Our assessments account for all of it, with measurements you can actually build from.
Fourth, prefab and panelized ADU systems are increasingly common in Los Angeles, and each one has site requirements that differ from conventional stick-built construction. We have hands-on familiarity with what companies like Abodu and Cover need for crane placement and foundation tolerance, and what Dvele requires for panel delivery. If you’re leaning toward a prefab unit, our site assessment will tell you whether your lot can actually accept the unit you want, not just whether the unit fits on paper.
The Kingswell Way is built for this reality. We never sell a one-size-fits-all assessment. We look at your specific parcel, your specific constraints, and we write down what we find. Every time.
What You Get in Writing
The written feasibility report is the centerpiece of our site assessment service. Here is what it includes:
- Buildable area map showing exactly where an ADU or garage conversion can go on your lot, with setbacks drawn to scale.
- Utility connection plan identifying where sewer, water, gas, and electrical will connect, and what upgrades are likely required.
- Zoning findings referencing the specific Los Angeles ordinance sections that apply to your parcel, including any overlays or special districts.
- Constraints list covering slope, drainage, protected trees, access limitations, and any other factor that will affect design or budget.
- Recommended ADU types matched to your lot. This might be an attached JADU, a detached stick-built unit, a garage conversion, or a prefab unit from a manufacturer like Cover or Abodu, depending on what your parcel can actually support.
- Preliminary cost range for the ADU project itself, so you know what you’re getting into before design fees accrue.
This report is yours. You can use it to solicit bids from other contractors, to present to a lender, or to move forward with Lodgewick. We stand behind its accuracy. If something in the report proves incorrect and it costs you money, our 365-Day Done Right Promise applies. We come back and make it right. That commitment is in writing on every project we do.
Site Assessment vs. Survey vs. Soil Test
Homeowners often ask whether a site assessment is the same as a property survey or a soils report. It is not, and knowing the difference keeps you from paying for the wrong thing at the wrong time.
- Site assessment is the comprehensive feasibility look: zoning, utilities, drainage, access, buildable area, and preliminary cost. It answers the question “Can I build an ADU here, and what will it take?”
- Property survey is a precise legal boundary measurement performed by a licensed surveyor. Los Angeles often requires a survey as part of the permit application, but the survey does not assess feasibility. It only establishes exact property lines.
- Soils test or geotechnical report is an engineering analysis of the ground beneath the foundation. Hillside lots, canyon properties, and some expansion projects require one. It is performed by a geotechnical engineer, not by an ADU contractor.
We arrange all three as needed, and we coordinate the timing so you don’t pay for a survey or a soils test until the site assessment has confirmed the project is feasible in the first place. That sequencing alone saves Los Angeles homeowners thousands of dollars on projects that never should have moved forward.
When you work with Lodgewick on a site assessment, we’re part of the full process from home feasibility through design, permitting, and construction. You always know who to call, and a live person answers 24 hours a day, 7 days a week.
FAQs – Site Assessment
How much does a site assessment cost in Los Angeles?
A site assessment in Los Angeles typically costs $450 to $1,800, with flat city lots on the lower end and hillside or canyon lots on the higher end. The written feasibility report is included in that price, and the phone consultation before you commit is free. Call (213) 698-7116 for an exact quote on your parcel, with no obligation.
How long does a site assessment take?
Our site assessments in Los Angeles take 5 to 10 business days from the on-site walkthrough to the delivery of your written report. The initial parcel review starts within 3 business days of your signed estimate. If you have a deadline, tell us when you call, and we’ll work with your timeline.
Do I need a site assessment before designing my ADU?
Yes, in most cases. A site assessment in Los Angeles confirms your lot can support an ADU at all, and it identifies constraints like setback limits, utility capacity, slope issues, and access problems before you spend money on design work. Skip it and you risk designing a unit that cannot be permitted or that requires expensive changes later. If you already have a designer engaged, our report slots into their process and gives them accurate site data from day one.
What if my site assessment says I can’t build an ADU?
Then we tell you that in plain writing and stop you from spending money on a design that will never get a permit. In many cases, the assessment identifies a different path: a smaller unit, a different placement on the lot, or a garage conversion instead of a detached build. In the rare case that no ADU is feasible on your parcel, you’ll know before you’ve spent thousands on design and engineering. That is the value of doing this step first. Call (213) 698-7116 to schedule your assessment and get a straight answer about your lot.
