The short answer
A 1031 exchange lets you sell a rent-regulated building and buy replacement property in another state or of another type, such as unregulated apartments, DST interests or a net-leased commercial building, with no tax on the gain. Federal law treats all US real property as like-kind, so moving from regulated housing in California, Oregon, New York City or St. Paul into commercial property elsewhere is an ordinary exchange. Three things need attention: the regulation itself shapes your price and buyer pool, the replacement may be regulated too, and some states, California in particular, keep track of the deferred gain after you leave.

| California statewide cap | 5% plus inflation or 10%, whichever is lower, per 12 months, until January 1, 2030 |
|---|---|
| California new-building exemption | Housing with a certificate of occupancy issued within the previous 15 years |
| Oregon statewide cap | 7% plus inflation or 10%, whichever is lower, published each year by September 30 |
| Oregon new-building exemption | First certificate of occupancy less than 15 years before the increase notice |
| New York City | The Rent Guidelines Board sets adjustments for about one million rent-stabilized units |
| St. Paul, Minnesota | 3% per 12 months, with exceptions the city must approve or that landlords self-certify |
| Like-kind reach | Any US real property for any US real property under section 1031 |
| California after an out-of-state exchange | Form FTB 3840 every year until the deferred gain is recognized |
Know exactly which rule covers your building, because it sets both your rents and your buyer's math
California's statewide limit in Civil Code section 1947.12 caps increases over any 12 months at 5% plus the change in the cost of living, or 10%, whichever is lower. It exempts housing with a certificate of occupancy issued within the previous 15 years, and separately saleable homes and condominiums when the owner is not a REIT, a corporation or an LLC with a corporate member and the tenants received the statutory notice. The section is repealed on January 1, 2030 unless extended. Local ordinances can be stricter, within the limits of the Costa-Hawkins Act in Civil Code section 1954.52, which lets owners set rents for units first certified for occupancy after February 1, 1995.
Oregon's ORS 90.323 and 90.324 cap annual increases at 7% plus inflation or 10%, whichever is lower, with the state publishing the figure by September 30, and exempt units whose first certificate of occupancy is less than 15 years old. In New York City the Rent Guidelines Board sets the adjustments for about one million units under the Rent Stabilization Law. In Minnesota, St. Paul's ordinance limits increases to 3% in a 12-month period, with exceptions and a new-construction exemption added by amendment.
Look at the rule from the buyer's side as well as yours. A California house exempt in your hands under the individual-owner exemption is not exempt for a corporate or REIT buyer, which narrows who can pay the most.
Regulation lowers the income a buyer can underwrite, so price on today's rents, not market rents
A buyer of a regulated building is buying the existing rent roll plus whatever increases the rule allows. An investor can count only those rents, so a below-market regulated rent roll, more than the building's condition or replacement cost, drives what a buyer can pay.
The tax arithmetic is unaffected: your gain is the sale price less adjusted basis, and an exchange defers it whatever the price. A lower price does mean less equity to reinvest, so it is worth comparing the after-tax proceeds of selling now against holding with capped increases.
California owners have one more exit: under the Ellis Act, Government Code section 7060, a public entity cannot compel an owner to keep offering residential property for rent. Withdrawing units carries local procedures and tenant protections, so speak to a landlord-tenant attorney before treating it as a way to sell vacant.
Hypothetical: a $3,000,000 California building exchanged into property outside the state
Hypothetical: you sell a 12-unit California building for $3,000,000 with an adjusted basis of $900,000, a $2,100,000 gain, and buy replacement property in other states. Run your own numbers with your CPA; depreciation, debt and state tax all matter.
- Taxable sale: escrow would withhold $100,000, 3 1/3% of the price, under the Form 593 rules, and the full gain would be taxed federally and by California.
- Full exchange: no withholding at the initial transfer of a deferred exchange, no federal or California tax now, and replacement anywhere in the US under section 1031.
- After the exchange: you file Form FTB 3840 every year until the deferred California-source gain is recognized, and a later taxable sale is taxed by California on that gain even if neither you nor the property is there.
- Cash taken out above $1,500 is boot, taxable at both levels and subject to withholding.
- Other states have their own closing-table rules; states that withhold at closing lists them, and state tax on deferred gain explains which states keep a claim after you exchange out.
Choose a replacement that is actually unregulated, or regulated in a way you accept
Moving within the same state may not escape regulation: Oregon's and California's caps are statewide, with exemptions mainly for newer buildings and certain individually owned homes. Out-of-state apartments, newer construction, or commercial property such as industrial, retail or medical office, which these residential rules do not reach, all change the exposure.
DST interests are a common route out of hands-on residential ownership. Check where each trust's property sits, because a multifamily DST in a regulated city carries the same rules you are leaving; DST asset classes compares sectors, and apartment building exchanges covers the residential-to-residential case.
Check the state you are moving into as well, using the California and Oregon state pages and the page for your destination state.
Sequence the exit: rent roll, legal review, intermediary, then the 45-day list
Assemble the rent roll with each unit's regulated status, the registration or notice filings your city requires and any pending petitions, because a buyer's lender will underwrite them. Have a landlord-tenant attorney confirm the building's status before you set a price. Pull your depreciation schedule too, so you know the adjusted basis and how much of the gain is depreciation, the part taxed at up to 25%.
Sign the exchange agreement before closing and prepare the identification list early. The 45 days start at closing, and if the plan is to diversify out of one city into several properties or DST interests, the three-property and 200% identification rules in Reg. section 1.1031(k)-1(c)(4) set how wide the list can be.
Related questions
Can I exchange a rent-controlled apartment building for a warehouse?
Yes. All US real property held for investment or business use is like-kind to all other US real property, so apartments can be exchanged for industrial, retail, land or DST interests.
Does rent control affect whether my building qualifies for a 1031?
No. Qualification depends on holding the property for investment or business use, not on the rents you are allowed to charge.
Will California tax my gain if I exchange into property in another state?
Not at the exchange. California keeps the deferred gain as California-source and taxes it when it is recognized later, and you report the exchange on Form FTB 3840 each year until then.
Is a single-family rental in California under the statewide cap?
Only if it fails the exemption: a separately saleable home owned by an individual, not a REIT, corporation or LLC with a corporate member, is exempt if the tenants received the statutory notice. Local ordinances may still apply.
Do Oregon's rules apply to every rental in the state?
The statewide cap applies broadly but exempts units whose first certificate of occupancy is less than 15 years old and certain affordable units, so a newer Oregon building can be a replacement outside the cap for a time.
