How much is ADT in St. Louis: $53.99/mo*, $99 install, and the three plans people actually order
The number people want is the monthly. In St. Louis it currently starts at $53.99/mo* for ADT Secure+. Home Security Systems St Louis quotes that number on (314) 673-6003. SafeStreets installs. ADT monitors 24/7. This site is not ADT corporate. St. Louis Security Pros is the lockup. The monthly is not the whole quote. Install, term, permit desk, and backup still have to be said out loud.
Secure+ is $53.99*. Smart+ is $63.99* and is the plan most St. Louis orders pick. Complete+ is $74.99*. Many plans have a $99 install*. A new monitoring agreement is required — typically 36 months. Early termination fees apply. Credit approval applies. Offers are for homeowners. Qualifying monitoring can include a free alarm-system promo ($850 value)*. Those are the four numbers. Everything else on this page is which number fits which house.
ADT Secure+ at $53.99 is doors, windows, and 24/7
Secure+ is the honest first number if you want the house watched. Door and window sensors, a keypad, the ADT app, and 24/7 professional monitoring. It includes the garage walk-through if we count it. It does not include a doorbell. It does not include outdoor cameras. It still reaches ADT if we put cellular backup on the quote. A Soulard bungalow with a porch door and a side door is often this plan plus a leftover-keypad photo.
People skip Secure+ because they think cameras are the product. Cameras are Complete+. The product on Secure+ is a door that opens while you sit on I-64. ADT can call you. A camera you forget to check from Clayton cannot. If a Soulard board or a downtown loft board forbids cameras in the hall, Secure+ still counts. Indoor sensors plus 24/7 is still ADT monitoring.
Ask whether the $99 install applies on Secure+ for this address. Ask what equipment is in the $850 promo if you qualify. Ask whether a leftover keypad on a Kirkwood resale can be reactivated instead of replaced. Reactivate can change the install conversation. Replace is the usual path on builder leftovers. Leftover keypads is that photo article.
Secure+ at $53.99 adds smoke or carbon monoxide
Secure+ is Secure+ plus one life-safety device — smoke or carbon monoxide. South-city brick houses with boilers and west-county two-stories with attached garages are the usual step-up. It is not a fire department contract. It is a monitored detector on the same ADT watch. If you already have local smoke that is not monitored, say so. We will not pretend a battery smoke on a Hill ceiling is ADT.
St. Louis Fire Department nuisance-alarm rules are not the same as SLMPD burglar-alarm paper. Do not mix them on the quote. This site quotes burglar monitoring. If you want monitored smoke, Secure+ is the spoken step. Confirm on the call. Do not invent a fire-permit dollar. The burglar desk is still ARFAM inside the city.
Four dollars a month is the gap from Secure+ to Secure+. People pay it when they want the same 24/7 path for smoke or CO. People skip it when they only want the door. Either is a real occupancy choice. Say which.
Smart+ at $63.99 is the plan most St. Louis orders pick
Smart+ adds a lock, a thermostat, or a garage opener on the same app. That is why it is popular. You can arm from I-64, I-70, I-44, or I-55. You can grant a neighbor a lock code while you sit in Kirkwood car line. A lock is not monitoring. ADT watching the door is monitoring. Keep those jobs straight on the call.
Chesterfield and Ballwin lots with long driveways often want the garage on the app. Downtown lofts often want the lock. Soulard houses often want the garage walk-through counted first and the lock second. We will not copy a west-county garage kit onto a Lafayette Square porch. Count the openings. Then pick the Smart+ add.
Smart+ still starts with doors and windows. If you skip contacts and only buy a lock, you do not have ADT watching the house. The $63.99* number assumes the Secure+ core plus the smart add. Ask what is included. Ask whether the install stays at $99*. Ask about backup so the panel still reaches ADT if Ameren Missouri drops while you are on the highway.
Complete+ at $74.99 is video, and some installs go higher
Complete+ adds doorbell and camera options in the ADT app. Soulard, Lafayette Square, and Downtown stoops collect boxes. That is why people add a doorbell. Outdoor cameras are extra. Some camera packages have a higher install than $99. Hear that before you hang up. Do not assume twelve cameras. Count the porch. Count the driveway. Bring HOA camera rules on Chesterfield, Ballwin, Town and Country, and OFallon plats.
A doorbell lets you see a box. It does not call SLMPD. ADT watching a door contact can request help when it is appropriate after a sensor trips. If you only want the door watched, stay on Secure+. If you want eyes on the stoop and 24/7 on the door, say Complete+ and hear the install. Soulard and Lafayette Square porches is the box article. HOA cameras is the board article.
Video without a path is decoration. Ask about cellular backup on Complete the same way you ask on Secure+. An Ameren blink kills Wi-Fi. A camera you cannot reach is not monitoring. Indoor contacts plus 24/7 plus backup is the core. Video is extra.
The $99 install and the $850 promo, said in plain English
Many plans have a $99 customer installation charge*. That is not “activation†as a marketing word. It is the install. Complete+ with outdoor cameras may be higher. Ask. The $850 free alarm-system promo on qualifying monitoring* is equipment credit on a new 36-month agreement — not a box of sensors in the garage. Homeowners only. Credit approval applies. Early termination fees apply. Cannot be combined with other offers. Not on purchases from ADT LLC.
The spoken quote should name monthly, install, term, desk, and backup. If any of those five is missing, ask again. A banner on this site is not the offer. The number you hear on (314) 673-6003 is the offer. Prices change. Equipment changes. The four plan names on packages are the locked tiers: Secure+, Smart+, Complete+. We do not quote Traditional $36.99 or Remote $53.99 on this site.
Permit dollars are not the monthly, but they still cost money
City of St. Louis ARFAM is $25 residential. That is not the $53.99 monitoring. For a monitored system the alarm company collects the ARFAM fee. Unincorporated St. Louis County Chapter 720 bills $25 per false alarm police respond to. Chesterfield Chapter 610 is $25 / $50 / $100. St. Charles is a one-time $25 registration, waived at 60+. OFallon is warnings then $100. Those dollars sit next to the monthly. They are not ADT. They are the desk. Permits is the comparison.
False alarms also cost time. Teach the household. Cancel inside the window the specialist names. A delivery is not a reason to skip monitoring. It is a reason to teach the cancel. The monthly still starts at $53.99*. The desk still changes with the ZIP.
What a Kirkwood house costs versus a Chesterfield lot
The three plans do not change with the suburb. The opening count does. A Kirkwood craftsman with a porch door, a side door, and a garage walk-through is more contacts than a downtown loft with two doors. A Chesterfield lot with an extra unit is a second door list. Smart+ may add the garage. Complete+ may add the driveway camera if the board allows it. The monthly still sits on one of the four numbers. The install may move if cameras pile up.
Do not compare a Complete+ camera quote on a Town and Country lot to a Secure+ quote on a Soulard bungalow and call it a St. Louis price. Compare the same occupancy card. House versus condo. Leftover versus new. Cameras yes or no. Then the $53.99 / $63.99 / $74.99 ladder makes sense.
Coverage is same-day or next-day when the ZIP qualifies. We confirm the calendar on the call. Kansas City is not this line. Springfield, Columbia, and Branson are not this line. Confirm the ZIP. Then hear the number.
Ask these on the 314 call before you agree
- Which of the three plans matches the openings we just listed?
- Is the install $99, or is it higher because of cameras?
- How long is the agreement, and what is the early termination fee?
- Does this ZIP need an alarm permit, and who collects it?
- If Ameren Missouri or Wi-Fi drops, can the panel still reach ADT?
- Is the leftover keypad a reactivate or a replace?
Florissant, Ferguson, Mehlville, and Arnold are not a cheaper plan
North-county and south-county ZIPs still sit on the same four numbers. Florissant 63033, Ferguson 63135, Mehlville 63125, Oakville 63129, Affton 63123, and Arnold 63010 do not get a secret fifth plan. The opening count still decides Secure+ versus Smart+. The desk still decides the permit dollar. Unincorporated Mehlville, Oakville, and Affton lots often sit under St. Louis County Chapter 720, which bills $25 on every false alarm police respond to. That $25 is not the $53.99 monthly. Say the ZIP so we do not quote City of St. Louis ARFAM on a 63125 house.
Arnold is Jefferson County. Fox School District drop-off empties those houses toward I-55. The monthly is still $53.99* on Secure+. The desk is not SLMPD. Confirm from the ZIP. We do not invent an Arnold residential permit dollar. We still count the garage. We still ask about backup on Ameren Missouri.
What the spoken quote should include, line by line
Monthly on one of the three plans. Install, $99 or higher if cameras pile up. Term, typically 36 months, with early termination fees. Occupancy, homeowners only on the promo. Desk, ARFAM $25 inside the city or the collar-city rule. Backup, so the panel still reaches ADT if Ameren Missouri or Cuivre River drops. Leftover, reactivate versus replace. That is seven lines. If the specialist skips one, ask it. A website banner cannot hold all seven. The 314 call can.
Call (314) 673-6003. There is no form. St. Louis homeowners can trust a SafeStreets security system monitored by ADT. The monthly starts at $53.99*. The rest of the quote is the house in front of you.
