We handle property marketplace website development in Los Angeles for founders, landlords and property managers who want to earn from listings, applications and stays across the city and the county around it. Codeeo builds the owner onboarding, the rules engine that knows which city a unit sits in, the application and booking checkout, and the payout system that keeps your share and pays owners on schedule. California sets strict rules on fees, deposits and privacy, and Los Angeles adds its own, so the platform enforces them at the point of listing and payment.
A renter scrolling from Koreatown to Culver City is crossing city lines without noticing. Your marketplace has to notice, because rules that apply to a rent stabilized unit or a short stay change at those boundaries. The same is true for which owners must show a license number and which fees count as mandatory.

What we build
Los Angeles is not one rental market. It is the City of Los Angeles plus dozens of neighboring cities such as Santa Monica, West Hollywood, Pasadena, Glendale and Long Beach, each with its own housing rules, inside a state that regulates rental fees and personal data more closely than most. A good property listing marketplace platform development Los Angeles plan accepts that from the start. These are the components we usually build, beginning with the ones that control what owners can charge and what renters must be told.
Every address is matched to its city and, inside the City of Los Angeles, flagged for whether the unit may fall under the Rent Stabilization Ordinance. Listing fields, required notices and allowed listing types change with that answer, and your team can update the rules as cities amend them.
Owners cannot publish a listing that ignores where the unit is.
The City of Los Angeles Home-Sharing Ordinance requires hosts to register and platforms to display the registration number. The listing form requires the number for short stays in the city, stores proof, and blocks publication without it. Other cities in the county get their own rule sets.
Short stay listings that can stay live.
California Civil Code 1950.6 limits rental application screening fees, adjusted each year, and requires an itemized receipt. The checkout caps the fee at the current limit your team sets, issues the receipt automatically and refunds the unused portion when no screening is run.
Application revenue without fee complaints.
Since July 2024 California has limited most residential security deposits to one month's rent, with a narrow exception for some small landlords. Owners choose the rule that applies to them, the platform checks the amount against rent, and move-in funds are split between owner and platform at payment.
Deposits that match state law before money moves.
Owners verify identity through the payment provider and prove control of the unit with a deed, county assessor record or management agreement. Licensed agents add their DRE license number, which California requires on their marketing, and the platform shows it on their listings.
Renters deal with verified owners and licensed agents.
Accessory dwelling units, guesthouses and single rooms have their own listing type with shared utility notes, separate entrance details, parking and occupancy terms. Homeowners who built an ADU can list it in minutes and get paid through the same payout system as larger landlords.
A large and growing source of small landlord supply.
California's Honest Pricing Law requires mandatory fees to be included in the advertised price. Listings and checkout show the total a renter or guest will pay, including your platform fee, rather than adding it at the last step.
No surprise fees and no drip pricing exposure.
Spanish is essential across Los Angeles, and Korean, Armenian, Chinese and Tagalog speakers make up large renter groups in parts of the city. We build translated interfaces, language labels on owner descriptions and support routing by language.
More renters complete an application without leaving.
A self service page where Californians can access, correct or delete their data, opt out of sale or sharing, and limit the use of sensitive information. Requests are logged with deadlines, and the platform honors Global Privacy Control signals from browsers.
Privacy requests handled on time with a record.
Owners are paid on a schedule you set through a marketplace payment provider, with commission taken at the split. Disputes over refunds, unit condition or cancellations run through a case system with evidence and decisions, and reviews open only after a verified stay or lease.
Trust built on records rather than arguments.
Who this is for
Each of these groups faces a different mix of rules and a different first source of supply. We scope the first release around the group you serve first, then expand the rules engine and listing types as you grow into other parts of the county. Across all four, the same rule holds: the platform should enforce California's limits automatically, so owners cannot break them by accident.
Many Los Angeles homeowners have added a backyard unit and do not want a property manager. A marketplace that helps them list, screen applicants under California fee rules, collect a compliant deposit and get paid monthly is a clear offer. We focus the first release on simple onboarding, guided listing and payouts, because these owners are new to renting. Later releases can add lease templates, renewal reminders and rent collection, so the platform earns every month the unit stays rented rather than only at move-in.
Owner education screens matter as much as features here.
Students rent rooms and shared units by the academic year, often with parents paying. We build group applications, split rent among roommates, guarantor flows and term based availability. Listings near Westwood and University Park carry clear walking and transit times, and payments come from several payers per lease. Parents can pay their share without seeing other roommates' details, and every payer gets their own receipt.
You manage buildings in Hollywood, Mid City and the Valley and want small landlords to list through you for a fee. The platform keeps your managed units and outside listings separate in payouts and responsibility, and the rules engine applies the RSO flag and city rules to both. Your leasing team keeps one inbox for both kinds of inquiry, with clear labels showing which units you manage and which you only market.
Niche platforms for film production housing, medical stays or pet friendly homes can compete with the giants if they serve one audience well. We build registration checks, total price display, occupancy tax lines your adviser confirms and fast payouts, so hosts trust a smaller platform with their bookings. Hosts outside the City of Los Angeles, in Santa Monica or West Hollywood for example, get the rule set for their own city, so one platform can serve several jurisdictions without manual checks on each listing.
Short stay rules in LA change often; your rules engine must be easy to update.
How we work together
A fixed scope first release fits founders who need to launch in one area and prove the model. A monthly retainer fits live platforms adding cities, languages and listing types. A dedicated team fits operators running a long roadmap or several marketplaces. Our team works with Los Angeles clients remotely, and all discovery sessions, reviews and demos run over video call with a shared staging site and backlog. Rules work is part of every engagement: when a city amends a short stay or fee rule, we update the rule set, test the affected flows and release the change with a note your team can share with owners.
A defined build with a deadline
We agree what the product has to do, write it down with a price and a date, and build exactly that. Changes are priced before they are made, not discovered on the invoice.
A product that keeps evolving
Named engineers who work your hours, join your standups and stay on the codebase. You direct the backlog; we own the quality of what ships.
Something live that needs looking after
A monthly block of hours for improvements, fixes and the small requests that otherwise wait months. Unused hours carry for a quarter.
Technology
Commonly Next.js for fast, indexable listing pages, a Node or Laravel API, PostgreSQL with PostGIS for boundaries and map search, a marketplace payment provider and a consent management tool for California privacy signals.

More, because of the rules a California platform must enforce.
A Los Angeles marketplace needs a rules engine for city boundaries, rent stabilization flags, short stay registration and fee limits that other markets do not ask for. Privacy duties under CCPA and CPRA add a request center and consent handling. None of this is unusual for us, but it belongs in the first scope rather than being patched in after a complaint, so we plan it from discovery.
