SB 721 Inspection Cost in Los Angeles
There is no meaningful universal flat price for an SB 721 inspection, because the inspection scope is set by the specific property: how many elevated elements it has, what types they are and how they are built. RetroCal quotes each apartment property as a fixed fee after reviewing the building information.
What determines the cost of an SB 721 inspection?
The fee for our SB 721 inspection service follows the time a qualified, appropriately licensed professional needs on site and the documentation each sampled element requires. These are the factors that change it.
Property size and element count
The number of buildings and dwelling units sets the overall footprint, but the count that matters most is the qualifying exterior elevated elements, by type: balconies, exterior walkways, and exterior stairs and landings. Each type is sampled separately (see how the sample works), so a property with all three types has three samples to inspect and document.
Construction and access
Wood-framing configuration matters. Where joists, ledgers and posts are visible from below, the inspector can observe them directly. Where framing is concealed behind stucco, soffits or deck coatings, the inspector has to rely on surface evidence and instruments to judge what is behind the finish, which takes more time per element. The waterproofing configuration — the coating, flashing and drainage details at each element — has to be examined too. Access also changes the time on site: an underside reachable from the ground is quicker than one that needs ladders, lifts or scaffolding. In occupied buildings, balconies reached through units require tenant and access coordination.
Investigation methods
Moisture meters, infrared imaging and borescopes help assess concealed conditions. Where the evidence suggests concealed damage, a targeted opening may be needed to establish the condition of the framing. Whether openings are likely affects the scope.
Coordination and documentation
Some local jurisdictions have their own documentation or submission requirements. In the City of Los Angeles, the Los Angeles Housing Department calls this requirement E3; see Los Angeles Housing Department E3 inspections.
Does the 15% sample determine the price?
It shapes it. Health and Safety Code §17973 requires a random sample of at least 15 percent of each type of exterior elevated element. A property with balconies, walkways and stairs therefore has three separate samples, not one 15 percent sample of everything.
The 15 percent is a minimum. The inspector may expand the scope when observed conditions warrant it, which can add elements to the inspection.

Why two buildings with the same unit count can cost differently
Consider two 20-unit buildings. The first has four identical balconies with open framing visible from the ground. It has one element type, a small sample, direct access to the underside and little concealed framing.
The second is a courtyard building with balconies, several exterior stair systems and long runs of elevated walkways. It has three element types and three samples. The walkways cover far more surface than their count suggests, the undersides may be finished with stucco soffits that conceal the framing, and reaching them can take ladders or lifts. The unit count is identical; the inspection is not.

How to compare SB 721 inspection quotes
Quotes from different inspectors can describe different scopes. Ask each inspector the same questions so you are comparing like with like:
- Is the 15% sample applied to each element type separately?
- How is the sample selected, and is that documented in the report?
- Are moisture meters, infrared imaging or borescopes used, and are targeted openings included or billed separately?
- Will the inspector expand the scope if conditions warrant it, and how is that priced?
- Is every finding tied to a specific element and location, with photos?
- Is the report signed by the inspector, and is the 45-day delivery requirement understood?
- How are immediate safety conditions handled and reported?
- Is a repair-completion confirmation available after repairs, and is it included or separate?
- Are local submission or documentation requirements handled?
- How will you receive the proposal and the report, and can you follow the project's status?
A lower per-element number can describe a narrower scope. Compare what is included, not just the total.
What a RetroCal inspection proposal covers
The proposal is a fixed fee for the defined scope. It covers:
- An inventory of the qualifying exterior elevated elements
- The statutory sample of each element type
- Inspection by a qualified, appropriately licensed professional
- Field investigation with diagnostic instruments, with targeted openings only where the evidence calls for one, closed afterward
- Photographs of the inspected elements
- A signed report with findings, condition classification and recommendations, including further inspection where applicable — see what an SB 721 inspection report contains
Repairs are separate and optional. You are not required to hire RetroCal for repairs and may take the report to any licensed contractor.
How RetroCal prepares a quote
To scope the property, we need the address, the number of units and buildings, approximate counts of balconies and staircases, the approximate length of elevated walkways, the current condition, and any Los Angeles Housing Department E3 notice and its date. If the inspection is past due, see bringing an overdue inspection current.
After you submit the form, we follow up within one business day with a fixed-fee proposal. The proposal is sent by email and can be approved online. After approval, your private portal page shows the live status of the inspection and gives access to the report and project documents, and payments can be made online.
We work across the areas we serve in Los Angeles County.

SB 721 Inspection Cost FAQ
How much does an SB 721 inspection cost in Los Angeles?
There is no reliable universal number. RetroCal quotes each apartment property as a fixed fee after reviewing the building information. The fee is driven by the number and type of exterior elevated elements, how many fall into each statutory sample, how much framing is concealed, how the elements are accessed, how occupied units are coordinated and what documentation the local jurisdiction requires.
Does the number of balconies affect inspection cost?
Yes. Balconies are one element type, and at least 15 percent of them must be sampled. More balconies means more sampled balconies, and each sampled balcony takes time on site to access, examine, photograph and document.
Does the 15% rule mean only 15% of my property is inspected?
No. The 15 percent is a minimum for each type of exterior elevated element, not for the property as a whole. The inspector may expand the scope when observed conditions warrant it, and the owner remains responsible for the condition of every elevated element on the property, sampled or not.
Do exterior stairs and walkways affect the price?
Yes. Exterior stairs and landings and exterior walkways are separate element types with their own samples. On our quote form, walkways are measured by length, because long runs of elevated walkway take more time to inspect than their count alone suggests.
Is the written report included?
Yes. The signed, photo-documented report is part of the inspection. Health and Safety Code §17973 requires the report to be presented to the owner within 45 days of completing the inspection. RetroCal clients can access the report and related documents on their private portal page.
Does RetroCal charge separately if repairs are needed?
Yes. Repairs are a separate, optional proposal. There is no obligation to use RetroCal for repairs; you may take the report to any licensed contractor.
Can a property manager request pricing for several buildings at once?
Yes. Submit the form for one property and list the others in the message field, or call (818) 900-1233.
