Dahlcore Security Guard Services provides licensed commercial real estate security guards across New York City — Manhattan, Brooklyn, Queens, the Bronx, and Staten Island — plus Long Island and New York State. Property managers and building owners hire Dahlcore to protect office towers, mixed-use developments, multi-tenant buildings, corporate campuses, and retail centers — programs built around how commercial properties actually run, not adapted from residential or event templates. Founded in 2018 and led by Ian Dahlberg, who brings over 23 years of security experience, our veteran-owned team fields officers registered under New York’s Security Guard Act (General Business Law Article 7-A), with coverage from business-hours to 24/7/365, and it all begins with a free on-site security assessment.
Security for New York Commercial Real Estate
Commercial real estate security protects a building, its tenants, and the owner’s investment — through lobby control, tenant and after-hours access, patrols, and documented response. A 40-story Class A tower in Midtown has different needs than a mixed-use development in Long Island City or a retail center on Long Island, so Dahlcore designs each program from an on-site assessment rather than a template.
What We Cover, by Property Type
- Class A & B office buildings & corporate HQ — lobby screening, visitor badging, elevator-bank and floor access, after-hours control, and tenant coordination
- Mixed-use developments — separating public and private zones, monitoring shared entrances, managing package and vendor procedures, with one point of contact across tenant groups
- Retail centers & commercial corridors — visible deterrence, patrol, closing support, and de-escalation without disrupting the shopping environment
- Coverage modes — business-hours, extended, or 24/7/365, single building or multi-property portfolio, uniformed or plainclothes, armed or unarmed
The lobby is your building’s brand
Every tenant and visitor forms an impression at the front desk. A professional officer who screens visitors, badges guests, and enforces access consistently protects the building while reflecting its brand — the balance of security and hospitality that keeps tenants confident and renewing.
Why Property Managers & Owners Hire Dahlcore
Licensed, built for commercial real estate, and consistent across a portfolio — Dahlcore protects New York buildings and the tenant relationships that keep them full.
Licensed & Insured
Every officer is registered under New York’s Security Guard Act (General Business Law Article 7-A) with the NY Department of State’s Division of Licensing Services (NYSDOLS), background-checked and trained through DCJS-approved programs. Dahlcore is licensed, insured, and bonded, carrying general-liability ($1M / $2M) and workers’-compensation coverage; documentation is available on request.
Veteran-Owned, Led by the Owner
Dahlcore is veteran-owned and operated — founded in 2018 and led by Ian Dahlberg, who brings over 23 years of security experience — and the owner personally manages guards in the office and in the field. Clients reach security management directly for scheduling, incidents, and post-order updates.
Built for Commercial Real Estate
Post orders, training, and supervision are built around how office, mixed-use, and retail properties actually run — lobby brand and front-desk conduct, tenant and after-hours access control, elevator monitoring, and vendor coordination — not a generic security template.
Portfolio-Consistent Reporting
Real-time digital patrol logs and incident reports are standardized across every property, so any building can produce a coherent security record on short notice. Field supervisors conduct unannounced site checks, and clients have a named account contact — not a call center.

How Dahlcore Designs Your Program
A clear path from first walk-through to on-post coverage — no two properties get the same plan.
Free On-Site Assessment
A Dahlcore consultant walks your property, reviews existing systems, maps access points, and documents vulnerabilities — at no charge.
Risk & Compliance Review
We provide a written summary of identified risks, applicable New York compliance requirements, and recommended coverage — post hours, officer count, and technology needs.
Custom Program Proposal
Your proposal details officer assignments, shift schedules, technology coordination, and supervision protocols, scoped to your building.
Onboarding & Launch
Dahlcore handles officer assignment, post-order creation, system coordination, and a property-manager briefing before the first shift begins.
Ongoing Supervision & Review
Field supervisors run unannounced site checks, you get real-time reporting, and post orders are updated as the property changes.
One standard across your whole portfolio
Whether you manage one building or twenty across multiple boroughs, Dahlcore applies consistent post standards, reporting formats, and supervision so every location performs to the same level. Real-time reports give you visibility into what happened on any property without having to call — and a named account contact handles changes directly.
What Shapes Your CRE Security Plan
Dahlcore scopes every property to its class, tenants, and layout. These are the factors that shape the plan.
1. Property Type & Class
Class A or B office, mixed-use development, retail center, or corporate campus — each runs differently.
2. Coverage Hours & Posts
Lobby, elevators, docks, parking, and perimeter drive how many posts and which shifts — business-hours, extended, or 24/7/365.
3. Armed or Unarmed
Unarmed suits most commercial properties; armed guards (valid NYS pistol license, Penal Law §400) are available for higher-risk buildings after assessment.
4. Tenant & Compliance Needs
Tenant mix, after-hours access, and any fire-watch or building-compliance triggers shape the program.
5. Single Building or Portfolio
One property or a multi-property portfolio with standardized post orders and reporting across sites.

Where can I hire commercial real estate security guards in New York?
Dahlcore Security Guard Services provides licensed commercial real estate security guards across New York City — Manhattan, Brooklyn, Queens, the Bronx, and Staten Island — plus Long Island and New York State. We protect office towers, mixed-use developments, multi-tenant buildings, corporate campuses, and retail centers. Request a free, no-obligation security assessment or call 212-208-0900.
Are your guards licensed to work in New York?
Yes. Every officer holds a valid New York State security guard registration under the Security Guard Act (General Business Law Article 7-A), issued through the NY Department of State’s Division of Licensing Services (NYSDOLS), and completes NYS-mandated training — an 8-hour pre-assignment course, 16 hours of on-the-job training, and 8 hours of annual in-service — through DCJS-approved programs. Documentation is available on request.
What types of commercial properties does Dahlcore protect?
Class A and Class B office buildings, corporate headquarters, mixed-use developments, retail centers and commercial corridors, and multi-tenant commercial properties across the five NYC boroughs, Long Island, and New York State. Programs are available for single buildings and multi-property portfolios.
Do you offer 24/7 security coverage?
Yes. Dahlcore designs coverage for business hours only, extended evenings and weekends, or full 24/7/365 protection including holidays. Coverage recommendations are based on your property’s occupancy patterns, risk level, and priorities, and confirmed after a free assessment.
Do you provide FDNY fire watch in New York City?
Yes. When a fire-suppression, sprinkler, or alarm system is impaired — due to construction, equipment failure, or inspection — New York City’s Fire Code requires a fire watch. Dahlcore deploys FDNY-compliant fire watch officers with documented patrol logs, rapidly and subject to availability, 24/7. Fire watch is a core Dahlcore service alongside commercial building coverage.
Can you work with our existing access-control and camera systems?
Yes. Dahlcore officers operate alongside your existing access-control, CCTV, and visitor-management systems — administering credentials, monitoring feeds, and logging visitors — and coordinate with your building-management team. We don’t require you to replace your infrastructure; our officers strengthen the systems you already run.
How do you develop a security program for our property?
Dahlcore begins with a free on-site assessment — walking the property, reviewing systems, and mapping access points and vulnerabilities. From there we deliver a written risk-and-compliance review and a custom program proposal covering officer assignments, shifts, technology coordination, and supervision, then onboard with post orders and a property-manager briefing.
How quickly can Dahlcore start?
For standard commercial assignments, coverage can begin after a signed agreement, officer assignment, and post-order creation, subject to availability. For urgent needs — such as an FDNY fire watch when a system is impaired — Dahlcore works to deploy rapidly. Call 212-208-0900 to discuss your timeline; 24/7 support stands behind every post.
