Lost exemption notice: start with what you remember
Lost exemption notice is a common problem for Concord landlords. The notice arrived with a stack of other mail, got tossed in the recycling, and now you can’t recall whether it said your duplex was exempt or just that you needed to file something. The first step isn’t to panic. It’s to reconstruct what the notice likely said based on your property type and the ordinance’s structure.
Concord’s rent ordinance exempts certain properties: single-family homes, condos, and ADUs built after a certain date. Duplexes are trickier. If you own a duplex and live in one unit, you may have an owner-occupied exemption. If you don’t live there, the duplex might be fully covered by rent control. The notice you threw away was probably telling you which category you fell into, and whether you needed to file an exemption form or were automatically exempt.
Write down everything you remember: the date it arrived, any letterhead, any reference to a form number, whether it mentioned a deadline. Even a partial memory helps the city clerk narrow it down.
The real challenge: the city’s records are not your file
Here’s what most landlords get wrong. They assume the city has a copy of the notice and can just email it over. That’s not how it works. The city’s rent program office keeps records of what they sent, but those records are organized by property address and parcel number, not by your name. If you don’t know your parcel number or the exact address format they use, the search can take days. And even when they find it, they’ll often give you a summary, not the original document.
The other mistake is calling the wrong department. Concord’s rent program is housed under the city’s community development or housing division, not the county assessor. If you call the county, you’ll get transferred three times and end up with nothing. You need the specific office that administers the rent ordinance.
And there’s a timing issue. If the notice had a filing deadline and you missed it because you lost the notice, the city may not accept a late filing. You need to know whether the deadline has passed and what the penalty is. That’s where the real work begins.
A genuine partial answer: how to get the information from Concord’s rent program office
You can recover the exact requirements without the original notice. Here’s the sequence that works in Concord, based on how the office operates.
- Find your parcel number. Go to the Contra Costa County Assessor’s parcel lookup tool online. Enter your property address. The parcel number is an eight-digit code, usually starting with a three-digit map book number. Write it down.
- Call the Concord rent program office. Ask for the rent stabilization or rent review division. Tell them you lost your exemption notice and need to confirm your property’s status. Give them the parcel number and the full street address, including any unit number.
- Ask for a written confirmation. The person on the phone can often tell you verbally whether your property is exempt or covered, but you need it in writing for your file. Request a letter or email that states the exemption status, the date the original notice was sent, and any filing requirements or deadlines.
- If they can’t find your record, ask to speak with a supervisor. Sometimes the notice was sent to a previous owner or the address format in their system doesn’t match yours. A supervisor can search by owner name or parcel number.
This process usually takes one to three business days. The key is having the parcel number ready before you call. Without it, you’ll get bounced around.
What’s left after you get the city’s answer
Once the city confirms your exemption status, you still have work to do. The city’s letter will tell you whether you’re exempt or covered, but it won’t tell you what that means for your specific situation. For example, if you’re exempt as an owner-occupied duplex, you may still need to provide proof of occupancy each year. If you’re covered, you need to know the current rent cap and how to calculate allowable increases. The city’s letter is a starting point, not a compliance plan.
And here’s the part that depends on your property. If you have a tenant in place, the exemption status affects what you can charge and when you can increase rent. If you’re buying a property, the exemption status affects your underwriting. If you’re refinancing, the lender may ask for proof of exemption. The city’s letter answers the basic question, but not the operational ones.
That’s where a property management team that knows Concord’s ordinance comes in. We’ve walked through this with owners who lost their notices, and we know which follow-up questions to ask the city. We also keep a compliance file for every property we manage, so a lost notice never becomes a crisis. If you’re handling it yourself, our property management services can take this off your plate entirely.
How we walk you through it
When you contact us about a lost exemption notice, here’s what happens. First, we pull the property’s parcel number and any records we already have. If you’re an existing client, we may have a copy of the original notice in our file. If not, we start with the city.
We call the rent program office on your behalf, with your written authorization. We ask for the written confirmation and any missing forms. We check the current ordinance for any changes since the notice was sent. Then we build a compliance file: the exemption letter, the forms, the deadlines, and a calendar of when each item needs to be renewed or filed.
If the city says you missed a deadline, we find out what the late filing process is and whether there’s any leniency. If the city says you’re covered by rent control, we calculate your maximum allowable rent based on the current rules and your rent history. We also check whether any other exemptions apply, like the ADU exemption or the single-family carve-out.

Rebuild your file before you need it
The best time to rebuild a compliance file is before you get a notice from the city asking why you didn’t file. If you’ve lost your exemption notice, don’t wait. The city’s records are accessible, but the process takes time, and if you’re up against a deadline, that time matters.
We’ve seen owners put this off and then get hit with a rent increase challenge from a tenant who knows the ordinance better than they do. Rebuilding the file now costs less than defending a challenge later. And if you’re not sure whether your property is exempt, the only way to know is to ask the city directly.

What’s the most confusing part of Concord’s exemption process for you: the forms, the deadlines, or just figuring out which category your property falls into?
