AfterFast, Reliable Home Additions & ADU Across North Lauderdale
Home additions and ADU construction in North Lauderdale typically run $45,000-$130,000 for room additions and $90,000-$220,000 for detached ADUs, with most projects taking 3-6 months from permit to final inspection. We’re familiar with what these jobs actually involve on the ground in North Lauderdale - the pre-1985 CBS construction, the flat-roof tie-ins, the Broward County permit process that reviews aggregate values carefully. Our crews work these neighborhoods regularly, and scheduling is coordinated from our South Florida office so we can respond to North Lauderdale inquiries with same-week site visits. Call (754) 714-6540 to schedule your free estimate.
Why Rowan Construction Group Pompano Beach Is North Lauderdale’s Preferred Home Additions & ADU Company
We’ve built our reputation in North Lauderdale on showing our work before we do it - written prices, documented photo records, and signed change orders that keep projects within a few percent of the agreed number. Our Home Additions & ADU team has delivered 4,000-plus projects since 2007, every one with a flat written quote before any work started.
North Lauderdale homeowners find us the same way they research appliances - they read the three-star reviews, look for specific prices, and want documentation. We deliver: a written scope, a written warranty, and a 365-Day Done Right Promise backed by The Haven Standard, not a handshake. Under Clause 1, the price is written before anyone starts.
Response time to North Lauderdale is same-week for site visits, with permits and scheduling coordinated from our South Florida office. We know the local building officials, the FEMA flood zone maps that affect substantial improvement thresholds, and the specific failure modes of 1970s-era CBS construction. That local knowledge keeps permits moving and budgets intact.
Our Home Additions & ADU Services in North Lauderdale
ADU Design & Permitting
ADU design and permitting in North Lauderdale starts at $90,000 and runs to $220,000 for a detached unit. Because North Lauderdale is fully built out and landlocked, nearly every ADU permit is a substantial improvement on a pre-1985 CBS home - and Broward County building officials review aggregate permit values carefully. Additions in the city’s FEMA-mapped flood zones can trigger full current Florida Building Code compliance, turning a simple unit into a wind-load upgrade project. We front-load this risk: our preliminary inspection identifies code-trigger conditions before design is finalized, and we write allowances into the contract for the upgrades that may be required.
Garage Conversion ADU
Garage conversion ADUs in North Lauderdale range from $30,000-$80,000. These are popular in neighborhoods like Hampton Pines and around Kimberly Boulevard, where single-story CBS ranches with attached two-car garages dominate the housing stock. The challenge is what the garage slab and walls reveal once converted: original pre-code electrical, no engineered roof-to-wall connectors, and flat-roof waterproofing that has failed after 40-plus years of South Florida UV exposure. We schedule an inspection sign-off before framing closes, so any necessary corrections are priced and approved in writing - not discovered after drywall is up.
New Detached ADU
New detached ADUs face a specific North Lauderdale condition: Broward County’s high water table, often just 2-4 feet below grade. Any footings or utility trenching demand active dewatering even on routine residential projects. This isn’t a surprise we drop mid-build; it’s a line item in our written quote, with a documented allowance for dewatering duration based on season and soil conditions. We price the foundation work honestly because we’ve done enough of these to know what the ground holds.
Junior ADU & Interior Conversion
Junior ADUs and interior conversions - splitting an existing home into a separate unit - run toward the lower end of our addition range but carry the same code-upgrade risks. On a 1978 CBS ranch off SW 81st Avenue, our crew opened the rear wall for a 400 sq ft room addition and found the original pre-code electrical panel, undersized header framing, and failed flat-roof waterproofing at the tie-in. Because we had written allowances and a scheduled inspection sign-off into the contract before demo, we priced the panel replacement, sistered framing, and secondary water barrier as documented change orders the homeowner approved in writing - no surprises, no stalled draw schedule.
Room Additions
Room additions in North Lauderdale fall in the $45,000-$130,000 range. These are the most common substantial improvement we permit here, and they trigger the same inspection discipline: we open walls early, document conditions with our standard photo record, and write allowances for pre-code electrical, undersized framing, and flat-roof membrane failure. The homeowner sees what we see before we price the fix.
ADU Site Prep & Utilities
Site prep and utility work for ADUs in North Lauderdale requires planning for active dewatering and careful coordination with Broward County utility districts. We handle the trenching, connections, and inspections as part of our flat written price, with no work proceeding until the scope is documented.
Second Story Additions
Second story additions on North Lauderdale’s single-story CBS homes require structural analysis of the original slab and load-bearing walls. Many of these homes were built without engineered connectors between roof and wall. We identify this condition in our preliminary inspection and price the structural upgrade in the original quote, not as a mid-project surprise.
Sunrooms & Enclosed Patios
Sunrooms and enclosed patios are popular additions in North Lauderdale’s established neighborhoods, but they must tie into existing flat-roof systems that have often reached end of life. We inspect the membrane condition at the connection point and write replacement allowances into the contract when our photo record shows deterioration.

We source across fifty-plus vetted brands, giving our written quotes honest numbers rather than inflated ones. For North Lauderdale ADU and addition projects, we regularly specify Kohler fixtures and Moen plumbing hardware for wet areas, and we stock common replacement items locally so material delays don’t stall permitted work.

The brands are named in your written quote, not hidden behind a generic allowance.
Common Home Additions & ADU Problems We See in North Lauderdale Homes
- Pre-code electrical panels and aluminum wiring. Opening a wall for an addition on a 1970s North Lauderdale CBS home regularly reveals original electrical that won’t carry modern loads. We catch this in our pre-demo inspection sign-off and price the panel replacement as a documented change order before framing closes.
- Failed flat-roof waterproofing at tie-in points. South Florida’s UV exposure and hurricane-season wind events destroy flat-roof membranes faster than pitched systems. When we open a wall for an addition, we inspect the membrane condition at the connection and write replacement allowances into the contract - not as a surprise after water damage appears.
- No engineered roof-to-wall connectors. Pre-Andrew construction in North Lauderdale lacks the hurricane clips and secondary water barriers that current Florida Building Code requires. Our preliminary inspection identifies whether substantial improvement thresholds will trigger full compliance, and we price the wind-mitigation upgrade in the original quote.
- High water table during excavation. Broward County’s water table at 2-4 feet below grade means footings and utility trenches for ADUs need active dewatering. We include this in our written scope based on season and site conditions, not as a mid-project add-on.

FAQs - Home Additions & ADU in North Lauderdale
It usually doesn’t, when the quote is done right. The problem is pre-1985 CBS homes with conditions you can’t see until walls open: pre-code electrical, undersized framing, failed flat-roof waterproofing. We prevent cost overruns with a preliminary inspection, written allowances for likely conditions, and signed change orders before any corrective work proceeds. Call (754) 714-6540 for an exact quote - estimates are free.
Yes, if the aggregate permit value crosses substantial improvement thresholds on a FEMA-mapped flood zone lot. Broward County building officials review this carefully. We identify flood zone status in our preliminary research and write potential code-upgrade allowances into the original contract, so the homeowner knows the full range before permitting begins. Call (754) 714-6540 for a free estimate with flood zone analysis included.
The water table at 2-4 feet below grade means any excavation for footings or utilities requires active dewatering.

Call (754) 714-6540 for an exact quote - estimates are free.
Yes, if the underlying conditions are addressed: pre-code electrical must be brought to current Florida Building Code, structural connectors may need upgrading if substantial improvement thresholds are triggered, and flat-roof waterproofing at the conversion point must be intact. We inspect these conditions before quoting and write the necessary upgrades into the scope. Call (754) 714-6540 for a free estimate.
