Do Baldwin Park's rent limits apply to your rental purchase?

You’re considering a small apartment building or a non-owner-occupied duplex in Baldwin Park, and the rent after closing matters to the purchase. Start here: effective August 1, 2026, the maximum allowable rent increase for covered units is $3.70 for every $100 of rent.

The next question is whether the units are covered. The City of Baldwin Park’s rent stabilization rules generally cover residential rental units built before January 1, 1995, with exemptions that need a separate check. Before treating a possible increase as part of your purchase calculations, confirm coverage with the Housing Division.

This guide is educational, not legal or tax advice.

How does the city calculate the annual limit?

Ordinance No. 1522 uses an April-to-April inflation measurement and an August effective adjustment month.

Under section 117.04 of the Baldwin Park Municipal Code, the allowable increase for the next twelve months is the lesser of the change in the Consumer Price Index for All Urban Consumers for the Los Angeles-Long Beach-Anaheim area or $5 for every $100 of rent. The measurement covers the twelve months from April to April. The adjustment becomes effective in August following that period and applies for the next twelve months.

If the index change falls below the code’s floor, the landlord may increase rent up to $1 for every $100 of rent.

The city’s RSO page publishes the current $3.70 limit. Its Ordinance No. 1522 Q&A explains the fixed measurement and adjustment months. Before the amendment, the code did not specify a fixed month for the index data.

The staff report and ordinance text appear on the city’s agenda portal, under December 3, 2025, item 5, with second reading and adoption under December 17, 2025, item 6.

Which rental units are covered?

Residential rental units built before January 1, 1995 are covered unless an exemption applies.

Chapter 117 calls these “controlled rental units.” An older apartment building or non-owner-occupied duplex calls for a coverage check using the year built and the exemptions.

The city’s listed exemptions include:

• Single-family residential property that can be sold independently, including condominiums and townhomes.
• A single structure with two units where the owner occupies one.
• Units constructed after October 21, 2020, except units created through conversion.
• Certain government-owned or subsidized units where state or federal law exempts them, including affordable housing and Section 8 units.

The list also includes specified mobile homes, transient lodging, hospital and similar institutional units, and units used by nonprofits for childcare or residential social services. Ask the Housing Division which exemption, if any, applies to the property.

Ordinance No. 1522 also clarifies the single-family definition. A lot with a single-family home and lawful accessory dwelling units counts as a single-family home for this chapter, including those accessory units. The presence of a lawful ADU therefore belongs in the exemption discussion.

What has to be posted before an increase?

The landlord has a duty to post the maximum allowable rent before any increase.

Section 117.04 calls for posting for each unit in a prominent place in or about the affected controlled units. If the landlord does not post within seven days of the city’s notice, the fine is $250 for each day after the seventh day.

For your purchase review, ask the seller whether the maximum allowable rent has been posted for each unit and whether the city has sent any notice about posting. Discuss the seller’s answers with the Housing Division alongside the rent history.

An increase sets a new base rent ceiling for the unit. For tenancies that qualify for a vacancy rent increase under state law, the base rent ceiling is the initial rental rate when the tenancy begins. Ask how the recorded ceiling applies to each unit’s current tenancy before assuming a rent figure can change after closing.

Can a landlord request an increase above the maximum?

A landlord may petition for an upward adjustment above the maximum, with a hearing officer deciding the request.

Sections 117.05 and 117.06 provide the petition process. The city’s rules provide for final action within 120 days of filing, and appeals go to the City Council within ten days.

A “fair and reasonable rent” petition applies where the landlord is operating with negative cash flow due to existing rents and allowable costs or expenses. It must be submitted in writing on the city’s form.

Section 117.14 separately provides a just cause route for seeking an increase above $3 for every $100 of rent. That route calls for a written request with a factual basis, a hearing officer’s decision and an appeal to the council. Ask the Housing Division how that provision relates to the current published maximum and which process fits the proposed request.

What does annual rent registration involve?

Landlords must provide rent and tenancy information annually for every rental unit subject to the ordinance.

Under Chapter 117.15, registration is complete only when outstanding registration fees are paid and the required rent, tenancy and emergency contact information is provided.

There is a deadline discrepancy to resolve with the city. The city sets the annual registration deadline, but its RSO page and registration form give different dates. The 2026 Annual Rent Registry Form listed a fee of $28 per unit. Confirm the current annual registration deadline with the city.

That form asks for each unit’s move-in date, effective date of last increase and current monthly rent. It directs mailing to City of Baldwin Park, Code Enforcement, 14403 E. Pacific Avenue.

If you’re comparing holdings across cities, the guide to Santa Ana’s rental registry and a new owner addresses that separate city’s process.

What should you ask before closing?

Ask for the year built, the rent registry form and the records supporting each unit’s current rent and last increase.

M. had built his rental-purchase budget around the idea that he could adjust the rent after taking ownership. The existing rent was below what he had seen in nearby listings, so the assumption made the investment appear comfortable. Once Baldwin Park’s rent limits came up, he went back through the numbers without that automatic increase. Buying the property would not necessarily erase rules that already applied to it. That single point changed the conversation from potential rent to the property’s actual regulatory history.

You can contact the Housing Division at [email protected] or (626) 960-4011, Ext. 462. Ask whether the units are covered, what registration remains outstanding and how the last increase date affects the next proposed increase.

The short version

Covered Baldwin Park rentals have a current maximum allowable increase of $3.70 for every $100 of rent, effective August 1, 2026.

Confirm coverage using the year built and exemptions. Review each unit’s registry information, last increase date and current rent, then ask the Housing Division about posting, registration and any proposed petition.
